Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

Autotools: Fix dist tarball CTest bugs Add missing CTest files to tarball. Remove the generated version.h from libclamav sources so it isn't added to the dist. version.h should be generated at build time by both autotools builds and cmake builds. When included with the dist, it may cause clamd VERSION command checks to fail because clamd is compiled with the wrong version.h header. Also bumped the minimum CMake version for Windows to accomodate the file(GET_RUNTIME_DEPENDENCIES).

CMake: Fix support for external LLVM (3.6) Have to manually link libtinfo (`-ltinfo`) because our FindLLVM didn't add it to the LLVM_LIBRARIES variable for us. See: - https://stackoverflow.com/questions/21477407/llvm-3-5-fails-to-link Have to remove the CXX_STANDARD setting at the top of CMakeLists.txt because of c++90 / c++11 ABI compatibility issues w/ LLVM. See: - https://maleadt.github.io/LLVM.jl/dev/man/troubleshooting/ Rename "llvm/Config/config.h" "llvm/Config/llvm-config.h" because LLVM renamed it in 2.8. Have to link LLVM manually with the test binaries that use the clamav object library instead of libclamav shared library. CMake does not propagate library dependencies from object files. I tested on ubuntu:16.04 with LLVM 3.6 built from source using: ``` /usr/local/bin/cmake .. -D CMAKE_INSTALL_PREFIX=/opt/llvm/3.6 \ -D LLVM_ENABLE_RTTI=ON ``` Then built clamav w/: ``` /usr/local/bin/cmake .. -D CMAKE_INSTALL_PREFIX=`pwd`/install \ -D BYTECODE_RUNTIME="llvm" \ -D LLVM_ROOT_DIR="/opt/llvm/3.6" \ -D LLVM_FIND_VERSION="3.6.0" && make && make install ```

# CMAKE_CXX_STANDARD not set because we may need to match the compiler used to build LLVM.
# There's probably a good chance this issue will go away if using modern LLVM versions.
CMake: Add CTest support to match Autotools checks An ENABLE_TESTS CMake option is provided so that users can disable testing if they don't want it. Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required. Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav).

# libtool library versioning rules: http://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html
FIPS-compliant CVD signing and verification Add X509 certificate chain based signing with PKCS7-PEM external signatures distributed alongside CVD's in a custom .cvd.sign format. This new signing and verification mechanism is primarily in support of FIPS compliance. Fixes: https://github.com/Cisco-Talos/clamav/issues/564 Add a Rust implementation for parsing, verifying, and unpacking CVD files. Now installs a 'certs' directory in the app config directory (e.g. <prefix>/etc/certs). The install location is configurable. The CMake option to configure the CVD certs directory is: `-D CVD_CERTS_DIRECTORY=PATH` New options to set an alternative CVD certs directory: - Commandline for freshclam, clamd, clamscan, and sigtool is: `--cvdcertsdir PATH` - Env variable for freshclam, clamd, clamscan, and sigtool is: `CVD_CERTS_DIR` - Config option for freshclam and clamd is: `CVDCertsDirectory PATH` Sigtool: - Add sign/verify commands. - Also verify CDIFF external digital signatures when applying CDIFFs. - Place commonly used commands at the top of --help string. - Fix up manpage. Freshclam: - Will try to download .sign files to verify CVDs and CDIFFs. - Fix an issue where making a CLD would only include the CFG file for daily and not if patching any other database. libclamav.so: - Bump version to 13:0:1 (aka 12.1.0). - Also remove libclamav.map versioning. Resolves: https://github.com/Cisco-Talos/clamav/issues/1304 - Add two new API's to the public clamav.h header: ```c extern cl_error_t cl_cvdverify_ex(const char *file, const char *certs_directory); extern cl_error_t cl_cvdunpack_ex(const char *file, const char *dir, bool dont_verify, const char *certs_directory); ``` The original `cl_cvdverify` and `cl_cvdunpack` are deprecated. - Add `cl_engine_field` enum option `CL_ENGINE_CVDCERTSDIR`. You may set this option with `cl_engine_set_str` and get it with `cl_engine_get_str`, to override the compiled in default CVD certs directory. libfreshclam.so: Bump version to 4:0:0 (aka 4.0.0). Add sigtool sign/verify tests and test certs. Make it so downloadFile doesn't throw a warning if the server doesn't have the .sign file. Replace use of md5-based FP signatures in the unit tests with sha256-based FP signatures because the md5 implementation used by Python may be disabled in FIPS mode. Fixes: https://github.com/Cisco-Talos/clamav/issues/1411 CMake: Add logic to enable the Rust openssl-sys / openssl-rs crates to build against the same OpenSSL library as is used for the C build. The Rust unit test application must also link directly with libcrypto and libssl. Fix some log messages with missing new lines. Fix missing environment variable notes in --help messages and manpages. Deconflict CONFDIR/DATADIR/CERTSDIR variable names that are defined in clamav-config.h.in for libclamav from variable that had the same name for use in clamav applications that use the optparser. The 'clamav-test' certs for the unit tests will live for 10 years. The 'clamav-beta.crt' public cert will only live for 120 days and will be replaced before the stable release with a production 'clamav.crt'.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files.

The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav).

CMake: - Renamed ENABLE_DOCS to ENABLE_MAN_PAGES. - Fixed build issue when milter isn't enabled on Linux. Changed the default to build milter on non-macOS, non-Windows operating systems. - Fix LD_LIBRARY_PATH for tests including on macOS where LD_LIBRARY_PATH and DYLD_LIBRARY_PATH must be manually propagated to subprocesses. - Use UNKNOWN IMPORTED library instead of INTERFACE IMPORTED library for pdcurses, but still use INTERFACE IMPORTED for ncurses. UNKNOWN IMPORTED appears to be required so that we can use $<TARGET_FILE_DIR:Curses::curses> to collected the pdcurses library at install time on Windows. - When building with vcpkg on Windows, CMake will automatically install your app local dependencies (aka the DLL runtime dependencies). Meanwhile, file(GET_RUNTIME_DEPENDENCIES ...) doesn't appear to work correctly with vcpkg packages. The solution is to use a custom target that has CMake perform a local install to the unit_tests directory when using vcpkg. This is in fact far easier than using GET_RUNTIME_DEPENDENCIES in the unit_tests for assembling the test environment but we can't use this method for the non-vcpkg install because it won't collect checkDynamic.dll for us because we don't install our tests. We also can't link with the static check.lib because the static check.lib has pthreads symbols linked in and will conflict with our pthread.dll. TL;DR: We'll continue to use file(GET_RUNTIME_DEPENDENCIES ...) for assembling the test enviornment on non-vcpkg builds, and use the local install method for vcpkg builds. testcase.py: Wrapped a Pathlib.unlink() call in exception handling as the missing_ok optional parameter requires a Python version too new for common use. Remove localtime_r from win32 compat lib. localtime_r may be present in libcheck when building with vcpkg and while making it a static function would also solve the issue, using localtime_s instead like we do everywhere else should work just fine. check_clamd: Limited the max # of connections for the stress test on Mac to 850, to address issues found testing on macos-latest on GitHub Actions.

Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav).

GitHub Actions testing on Ubuntu, Mac, & Windows Updates to fix issues in the CMake install instructions. Updates the README.md to indicate that CMake is now preferred Adds a GitHub Actions badge, Discord badge, and logo to the README.md. CMake: - Renamed ENABLE_DOCS to ENABLE_MAN_PAGES. - Fixed build issue when milter isn't enabled on Linux. Changed the default to build milter on non-macOS, non-Windows operating systems. - Fix LD_LIBRARY_PATH for tests including on macOS where LD_LIBRARY_PATH and DYLD_LIBRARY_PATH must be manually propagated to subprocesses. - Use UNKNOWN IMPORTED library instead of INTERFACE IMPORTED library for pdcurses, but still use INTERFACE IMPORTED for ncurses. UNKNOWN IMPORTED appears to be required so that we can use $<TARGET_FILE_DIR:Curses::curses> to collected the pdcurses library at install time on Windows. - When building with vcpkg on Windows, CMake will automatically install your app local dependencies (aka the DLL runtime dependencies). Meanwhile, file(GET_RUNTIME_DEPENDENCIES ...) doesn't appear to work correctly with vcpkg packages. The solution is to use a custom target that has CMake perform a local install to the unit_tests directory when using vcpkg. This is in fact far easier than using GET_RUNTIME_DEPENDENCIES in the unit_tests for assembling the test environment but we can't use this method for the non-vcpkg install because it won't collect checkDynamic.dll for us because we don't install our tests. We also can't link with the static check.lib because the static check.lib has pthreads symbols linked in and will conflict with our pthread.dll. TL;DR: We'll continue to use file(GET_RUNTIME_DEPENDENCIES ...) for assembling the test enviornment on non-vcpkg builds, and use the local install method for vcpkg builds. testcase.py: Wrapped a Pathlib.unlink() call in exception handling as the missing_ok optional parameter requires a Python version too new for common use. Remove localtime_r from win32 compat lib. localtime_r may be present in libcheck when building with vcpkg and while making it a static function would also solve the issue, using localtime_s instead like we do everywhere else should work just fine. check_clamd: Limited the max # of connections for the stress test on Mac to 850, to address issues found testing on macos-latest on GitHub Actions.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs.

The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

GitHub Actions testing on Ubuntu, Mac, & Windows Updates to fix issues in the CMake install instructions. Updates the README.md to indicate that CMake is now preferred Adds a GitHub Actions badge, Discord badge, and logo to the README.md. CMake: - Renamed ENABLE_DOCS to ENABLE_MAN_PAGES. - Fixed build issue when milter isn't enabled on Linux. Changed the default to build milter on non-macOS, non-Windows operating systems. - Fix LD_LIBRARY_PATH for tests including on macOS where LD_LIBRARY_PATH and DYLD_LIBRARY_PATH must be manually propagated to subprocesses. - Use UNKNOWN IMPORTED library instead of INTERFACE IMPORTED library for pdcurses, but still use INTERFACE IMPORTED for ncurses. UNKNOWN IMPORTED appears to be required so that we can use $<TARGET_FILE_DIR:Curses::curses> to collected the pdcurses library at install time on Windows. - When building with vcpkg on Windows, CMake will automatically install your app local dependencies (aka the DLL runtime dependencies). Meanwhile, file(GET_RUNTIME_DEPENDENCIES ...) doesn't appear to work correctly with vcpkg packages. The solution is to use a custom target that has CMake perform a local install to the unit_tests directory when using vcpkg. This is in fact far easier than using GET_RUNTIME_DEPENDENCIES in the unit_tests for assembling the test environment but we can't use this method for the non-vcpkg install because it won't collect checkDynamic.dll for us because we don't install our tests. We also can't link with the static check.lib because the static check.lib has pthreads symbols linked in and will conflict with our pthread.dll. TL;DR: We'll continue to use file(GET_RUNTIME_DEPENDENCIES ...) for assembling the test enviornment on non-vcpkg builds, and use the local install method for vcpkg builds. testcase.py: Wrapped a Pathlib.unlink() call in exception handling as the missing_ok optional parameter requires a Python version too new for common use. Remove localtime_r from win32 compat lib. localtime_r may be present in libcheck when building with vcpkg and while making it a static function would also solve the issue, using localtime_s instead like we do everywhere else should work just fine. check_clamd: Limited the max # of connections for the stress test on Mac to 850, to address issues found testing on macos-latest on GitHub Actions.

# Set _GNU_SOURCE for O_LARGEFILE, O_CLOEXEC, O_DIRECTORY, O_NOFOLLOW, etc flags on older systems
Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source.

Also: - We can remove the libtinfo dependency that was hardcoded for the LLVM 3.6 support, and must remove it for the build to work on Alpine, macOS. - Also, increased the libcheck default timeout from 60s to 300s after experiencing a failure while testing this. - Also made one of the valgrind suppressions more generic to account for inline optimization differences observed in testing this.

CMake: Add CTest support to match Autotools checks An ENABLE_TESTS CMake option is provided so that users can disable testing if they don't want it. Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required. Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required. Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes.

Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

CMake: Add CPack TGZ source package feature Add options to build a source tarball. This will replace Autotools' `make dist` feature. Although CMake doesn't have an autogen step, this is still necessary if we want to bundle in a local copy of the online documentation or if we want to vendor dependencies from github/etc at configure time in the tarball.

The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

CMake: Add CPack TGZ source package feature Add options to build a source tarball. This will replace Autotools' `make dist` feature. Although CMake doesn't have an autogen step, this is still necessary if we want to bundle in a local copy of the online documentation or if we want to vendor dependencies from github/etc at configure time in the tarball.

CMake: support Xcode builds Xcode (and perhaps some other generators?) do not like targets that have only object files. See: https://cmake.org/cmake/help/latest/command/add_library.html#object-libraries And: https://cmake.org/pipermail/cmake/2016-May/063479.html This issue manifests when using `-G Xcode` on macOS as the library dylibs being missing when linking with other binaries. This commit removes the object libraries for libclamav, libfreshclam, libclamunrar_iface, libclamunrar, libclammspack, and (lib)common because they were used by static or shared libs that didn't themselves have any added sources. Add getter & setter for the debug flag, so it isn't referenced by unit tests or other code that links with libclamav. This is needed because global variables are exported symbols on Windows.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32.

To build the installer, install WIX and simply run `cpack -C Release` Also removed the explicit --config option from the clamav-clamonacc.service file because it should not be required and isn't being generated correctly when using autotools anyways, especially after changes in this commit.

Windows: Enable MSI installer to upgrade between feature versions The MSI installer can find previous ClamAV installs to non-standard locations such at D:\ClamAV instead of C:\Program Files\ClamAV but only if upgrading to a new patch version of the same feature version. E.g. can find an upgrade 1.0.0 to 1.0.1, but cannot automatically find and upgrade 1.0.1 to 1.1.0. This change will make it so all minor feature versions will store the install path to the same key in the registry. A consequence of this change is that you can no longer install multiple feature versions of ClamAV using the MSI installer. If you want multiple ClamAV minor versions installed on Windows you will need to install using the ZIP package. This change will not allow the MSI installer to automatically find and upgrade across different major versions. E.g. cannot find and upgrade 0.105.2 to 1.1.0 because the former is major version 0, and the latter is major version 1. This is intentional because it is more likely that there will be breaking changes to config files and other user interfaces when we go to ClamAV 2.0.0.

cmake: Fix Windows .msi installer At present the .msi installer is only installing documentation component files and the vcredist files but fails to install clamav libraries, programs, and dependencies. It appears that explicitly installing the NEWS & README files under the documentation component before calling "include(CPack)" was causing the MSI installer to think it needed to install the documentation component but nothing else. This commit removes the component name, since we don't want to use components in the Windows MSI installer anyways. This appears to resolve the issue so that the MSI installer installs all the desired files.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c.

CMake: Support to build deb, rpm, & macOS pkg packages CMake/CPack is already used to build: - TGZ source tarball - WiX-based installer (Windows) - ZIP install packages (Windows) This commit adds support for building: - macOS PKG installer - DEB package - RPM package This should also enable building FreeBSD packages, but while I was able to build all of the static dependencies using Mussels, CMake/CPack 3.20 doesn't appear to have the the FreeBSD generator despite being in the documentation. The package names are will be in this format: clamav-<version><suffix>.<os>.<arch>.<extension> This includes changing the Windows .zip and .msi installer names. E.g.: - clamav-0.104.0-rc.macos.x86_64.pkg - clamav-0.104.0-rc.win.win32.msi - clamav-0.104.0-rc.win.win32.zip - clamav-0.104.0-rc.win.x64.msi - clamav-0.104.0-rc.linux.x86_64.deb - clamav-0.104.0-rc.linux.x86_64.rpm Notes about building the packages: I've only tested this with building ClamAV using static dependencies that I build using the clamav_deps "host-static" recipes from the "clamav" Mussels cookbook. Eg: msl build clamav_deps -t host-static Here's an example configuration to build clam in this way, installing to /usr/local/clamav: ```sh cmake .. \ -D CMAKE_FIND_PACKAGE_PREFER_CONFIG=TRUE \ -D CMAKE_PREFIX_PATH=$HOME/.mussels/install/host-static \ -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CMAKE_MODULE_PATH=$HOME/.mussels/install/host-static/lib/cmake \ -D CMAKE_BUILD_TYPE=RelWithDebInfo \ -D ENABLE_EXAMPLES=OFF \ -D JSONC_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/json-c" \ -D JSONC_LIBRARY="$HOME/.mussels/install/host-static/lib/libjson-c.a" \ -D ENABLE_JSON_SHARED=OFF \ -D BZIP2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D BZIP2_LIBRARY_RELEASE="$HOME/.mussels/install/host-static/lib/libbz2_static.a" \ -D OPENSSL_ROOT_DIR="$HOME/.mussels/install/host-static" \ -D OPENSSL_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D OPENSSL_CRYPTO_LIBRARY="$HOME/.mussels/install/host-static/lib/libcrypto.a" \ -D OPENSSL_SSL_LIBRARY="$HOME/.mussels/install/host-static/lib/libssl.a" \ -D LIBXML2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/libxml2" \ -D LIBXML2_LIBRARY="$HOME/.mussels/install/host-static/lib/libxml2.a" \ -D PCRE2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D PCRE2_LIBRARY="$HOME/.mussels/install/host-static/lib/libpcre2-8.a" \ -D CURSES_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D CURSES_LIBRARY="$HOME/.mussels/install/host-static/lib/libncurses.a" \ -D ZLIB_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D ZLIB_LIBRARY="$HOME/.mussels/install/host-static/lib/libz.a" \ -D LIBCHECK_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D LIBCHECK_LIBRARY="$HOME/.mussels/install/host-static/lib/libcheck.a" ``` Set CPACK_PACKAGING_INSTALL_PREFIX to customize the resulting package's install location. This can be different than the install prefix. E.g.: ```sh -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CPACK_PACKAGING_INSTALL_PREFIX="/usr/local/clamav" \ ``` Then `make` and then one of these, depending on the platform: ```sh cpack # macOS: productbuild is default cpack -G DEB # Debian-based cpack -G RPM # RPM-based ``` On macOS you'll need to `pip3 install markdown` so that the NEWS.md file can be converted to html so it will render in the installer. On RPM-based systems, you'll need rpmbuild (install rpm-build) This commit also fixes an issue where the html manual (if present) was not correctly added to the Windows (or now other) install packages.

CMake: support Xcode builds Xcode (and perhaps some other generators?) do not like targets that have only object files. See: https://cmake.org/cmake/help/latest/command/add_library.html#object-libraries And: https://cmake.org/pipermail/cmake/2016-May/063479.html This issue manifests when using `-G Xcode` on macOS as the library dylibs being missing when linking with other binaries. This commit removes the object libraries for libclamav, libfreshclam, libclamunrar_iface, libclamunrar, libclammspack, and (lib)common because they were used by static or shared libs that didn't themselves have any added sources. Add getter & setter for the debug flag, so it isn't referenced by unit tests or other code that links with libclamav. This is needed because global variables are exported symbols on Windows.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32.

CMake: disable CMAKE_FIND_PACKAGE_PREFER_CONFIG option for libxml2 CMake has a pretty sweet alternative to pkg-config or to the older `package-config` script that you'd run with `--libs`, `--ldflags`, etc. CMake can (optionally) install a YourPackageConfig.cmake alongside your libs under `<prefix>/lib/cmake/<pkg>/<pkg>Config.cmake`.

CMake: revert Iconv module name to match upstream I'd foolishly set the Iconv detection module to use uppercase to differentiate it from the upstream (original) module. I also kind of forgot to change the documentation to use the uppercase name. In reviewing that, I decided it's better to match the upstream FindIconv.cmake module as closely as possible in case they fix the issue described here, so that we can stop carrying a custom module without breaking the CMake options for everyone: https://github.com/Cisco-Talos/clamav-devel/commit/b26cdc54532729ecbc5e48dce51534eeb9c5497c This reverts the CMake options for setting the Iconv include and library paths back to match the upstream before 0.104 ships with stable CMake support.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system.

CMake: Add CTest support to match Autotools checks An ENABLE_TESTS CMake option is provided so that users can disable testing if they don't want it. Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required. Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

CMake: Add CTest support to match Autotools checks An ENABLE_TESTS CMake option is provided so that users can disable testing if they don't want it. Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required. Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

clamd: Fix bug reporting memory stats, used by clamdtop ClamD's STATS API reports process memory stats on systems that provide the `mallinfo()` system call. This feature is used by ClamDTOP to show process memory usage. When we switched to the CMake build system, we neglected to add the check for the `mallinfo()` system call and so broke ClamD memory usage reporting. This commit adds the CMake check for `mallinfo()` and sets HAVE_MALLINFO, if found. Fixes: https://github.com/Cisco-Talos/clamav/issues/706 Jira: CLAM-2742

Code cleanup: More accurate variable types in bytecode modules The bytecode source files largely use `int` instead of the appropriate `cl_errot_t` for clamav status codes, as well for boolean variables. This hides warnings that would indicate bugs, and makes it harder to read the code. I haven't gone as in depth as with some other code cleanups. This largely just replaces function interfactes and ret variables that use `int` with `cl_error_t`. I also swapped a couple of `int`s to `bool`s. While doing so I found that the `cli_bytecode_context_setpdf()` function was incorrectly placed in the `bytecode_api.c` file instead of the next to similar functions (`cli_bytecode_context_setpe`, etc.) in bytecode.c. It's not an API function, so I moved it to the correct location. I also eliminated a couple of compiler warnings: - LLVM's CFG.h header emits a warning about a multi-line comment, so that crops up with using LLVM for the bytecode runtime. I disabled the warning through CMake. - C doesn't like using the `inline` keyword on cli_dbgmsg in the declaration in `bytecode2llvm.c` because we're compiling the bytecode runtimes as a separate object file from the rest of libclamav. It doesn't appear to be a functional issue, but I swapped that file over to use `cli_dbgmsg_no_inline()` instead, just in case. I would hope link-time-optimization will inline it anyways.

FIPS-compliant CVD signing and verification Add X509 certificate chain based signing with PKCS7-PEM external signatures distributed alongside CVD's in a custom .cvd.sign format. This new signing and verification mechanism is primarily in support of FIPS compliance. Fixes: https://github.com/Cisco-Talos/clamav/issues/564 Add a Rust implementation for parsing, verifying, and unpacking CVD files. Now installs a 'certs' directory in the app config directory (e.g. <prefix>/etc/certs). The install location is configurable. The CMake option to configure the CVD certs directory is: `-D CVD_CERTS_DIRECTORY=PATH` New options to set an alternative CVD certs directory: - Commandline for freshclam, clamd, clamscan, and sigtool is: `--cvdcertsdir PATH` - Env variable for freshclam, clamd, clamscan, and sigtool is: `CVD_CERTS_DIR` - Config option for freshclam and clamd is: `CVDCertsDirectory PATH` Sigtool: - Add sign/verify commands. - Also verify CDIFF external digital signatures when applying CDIFFs. - Place commonly used commands at the top of --help string. - Fix up manpage. Freshclam: - Will try to download .sign files to verify CVDs and CDIFFs. - Fix an issue where making a CLD would only include the CFG file for daily and not if patching any other database. libclamav.so: - Bump version to 13:0:1 (aka 12.1.0). - Also remove libclamav.map versioning. Resolves: https://github.com/Cisco-Talos/clamav/issues/1304 - Add two new API's to the public clamav.h header: ```c extern cl_error_t cl_cvdverify_ex(const char *file, const char *certs_directory); extern cl_error_t cl_cvdunpack_ex(const char *file, const char *dir, bool dont_verify, const char *certs_directory); ``` The original `cl_cvdverify` and `cl_cvdunpack` are deprecated. - Add `cl_engine_field` enum option `CL_ENGINE_CVDCERTSDIR`. You may set this option with `cl_engine_set_str` and get it with `cl_engine_get_str`, to override the compiled in default CVD certs directory. libfreshclam.so: Bump version to 4:0:0 (aka 4.0.0). Add sigtool sign/verify tests and test certs. Make it so downloadFile doesn't throw a warning if the server doesn't have the .sign file. Replace use of md5-based FP signatures in the unit tests with sha256-based FP signatures because the md5 implementation used by Python may be disabled in FIPS mode. Fixes: https://github.com/Cisco-Talos/clamav/issues/1411 CMake: Add logic to enable the Rust openssl-sys / openssl-rs crates to build against the same OpenSSL library as is used for the C build. The Rust unit test application must also link directly with libcrypto and libssl. Fix some log messages with missing new lines. Fix missing environment variable notes in --help messages and manpages. Deconflict CONFDIR/DATADIR/CERTSDIR variable names that are defined in clamav-config.h.in for libclamav from variable that had the same name for use in clamav applications that use the optparser.

build: Allow for absolute paths for config and db paths There are some merits of having the configs in `/etc/clamav` and the databases in `/var/lib/clamav` to match the way the distros all package it and so these directories can be mounted volumes if needed. The DATABASE_DIRECTORY and APP_CONFIG_DIRECTORY variables don't support absolute paths. This patch changes that.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

CMake: improve multiarch support In testing on Alpine, I found that most libs were installing to <prefix>/lib while libclamav installed to <prefix>/lib64. Those who like multiarch will advocate for lib64, though I only actually noticed it because clamscan failed to find libclamav.so! Anyways, they should all install to lib64 by default if that's what how the system is set up. Using ${CMAKE_INSTALL_FULL_LIBDIR} instead of <prefix>/lib will do that.

CMake: Support to build deb, rpm, & macOS pkg packages CMake/CPack is already used to build: - TGZ source tarball - WiX-based installer (Windows) - ZIP install packages (Windows) This commit adds support for building: - macOS PKG installer - DEB package - RPM package This should also enable building FreeBSD packages, but while I was able to build all of the static dependencies using Mussels, CMake/CPack 3.20 doesn't appear to have the the FreeBSD generator despite being in the documentation. The package names are will be in this format: clamav-<version><suffix>.<os>.<arch>.<extension> This includes changing the Windows .zip and .msi installer names. E.g.: - clamav-0.104.0-rc.macos.x86_64.pkg - clamav-0.104.0-rc.win.win32.msi - clamav-0.104.0-rc.win.win32.zip - clamav-0.104.0-rc.win.x64.msi - clamav-0.104.0-rc.linux.x86_64.deb - clamav-0.104.0-rc.linux.x86_64.rpm Notes about building the packages: I've only tested this with building ClamAV using static dependencies that I build using the clamav_deps "host-static" recipes from the "clamav" Mussels cookbook. Eg: msl build clamav_deps -t host-static Here's an example configuration to build clam in this way, installing to /usr/local/clamav: ```sh cmake .. \ -D CMAKE_FIND_PACKAGE_PREFER_CONFIG=TRUE \ -D CMAKE_PREFIX_PATH=$HOME/.mussels/install/host-static \ -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CMAKE_MODULE_PATH=$HOME/.mussels/install/host-static/lib/cmake \ -D CMAKE_BUILD_TYPE=RelWithDebInfo \ -D ENABLE_EXAMPLES=OFF \ -D JSONC_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/json-c" \ -D JSONC_LIBRARY="$HOME/.mussels/install/host-static/lib/libjson-c.a" \ -D ENABLE_JSON_SHARED=OFF \ -D BZIP2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D BZIP2_LIBRARY_RELEASE="$HOME/.mussels/install/host-static/lib/libbz2_static.a" \ -D OPENSSL_ROOT_DIR="$HOME/.mussels/install/host-static" \ -D OPENSSL_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D OPENSSL_CRYPTO_LIBRARY="$HOME/.mussels/install/host-static/lib/libcrypto.a" \ -D OPENSSL_SSL_LIBRARY="$HOME/.mussels/install/host-static/lib/libssl.a" \ -D LIBXML2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/libxml2" \ -D LIBXML2_LIBRARY="$HOME/.mussels/install/host-static/lib/libxml2.a" \ -D PCRE2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D PCRE2_LIBRARY="$HOME/.mussels/install/host-static/lib/libpcre2-8.a" \ -D CURSES_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D CURSES_LIBRARY="$HOME/.mussels/install/host-static/lib/libncurses.a" \ -D ZLIB_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D ZLIB_LIBRARY="$HOME/.mussels/install/host-static/lib/libz.a" \ -D LIBCHECK_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D LIBCHECK_LIBRARY="$HOME/.mussels/install/host-static/lib/libcheck.a" ``` Set CPACK_PACKAGING_INSTALL_PREFIX to customize the resulting package's install location. This can be different than the install prefix. E.g.: ```sh -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CPACK_PACKAGING_INSTALL_PREFIX="/usr/local/clamav" \ ``` Then `make` and then one of these, depending on the platform: ```sh cpack # macOS: productbuild is default cpack -G DEB # Debian-based cpack -G RPM # RPM-based ``` On macOS you'll need to `pip3 install markdown` so that the NEWS.md file can be converted to html so it will render in the installer. On RPM-based systems, you'll need rpmbuild (install rpm-build) This commit also fixes an issue where the html manual (if present) was not correctly added to the Windows (or now other) install packages.

Eg: msl build clamav_deps -t host-static Here's an example configuration to build clam in this way, installing to /usr/local/clamav: ```sh cmake .. \ -D CMAKE_FIND_PACKAGE_PREFER_CONFIG=TRUE \ -D CMAKE_PREFIX_PATH=$HOME/.mussels/install/host-static \ -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CMAKE_MODULE_PATH=$HOME/.mussels/install/host-static/lib/cmake \ -D CMAKE_BUILD_TYPE=RelWithDebInfo \ -D ENABLE_EXAMPLES=OFF \ -D JSONC_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/json-c" \ -D JSONC_LIBRARY="$HOME/.mussels/install/host-static/lib/libjson-c.a" \ -D ENABLE_JSON_SHARED=OFF \ -D BZIP2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D BZIP2_LIBRARY_RELEASE="$HOME/.mussels/install/host-static/lib/libbz2_static.a" \ -D OPENSSL_ROOT_DIR="$HOME/.mussels/install/host-static" \ -D OPENSSL_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D OPENSSL_CRYPTO_LIBRARY="$HOME/.mussels/install/host-static/lib/libcrypto.a" \ -D OPENSSL_SSL_LIBRARY="$HOME/.mussels/install/host-static/lib/libssl.a" \ -D LIBXML2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/libxml2" \ -D LIBXML2_LIBRARY="$HOME/.mussels/install/host-static/lib/libxml2.a" \ -D PCRE2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D PCRE2_LIBRARY="$HOME/.mussels/install/host-static/lib/libpcre2-8.a" \ -D CURSES_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D CURSES_LIBRARY="$HOME/.mussels/install/host-static/lib/libncurses.a" \ -D ZLIB_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D ZLIB_LIBRARY="$HOME/.mussels/install/host-static/lib/libz.a" \ -D LIBCHECK_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D LIBCHECK_LIBRARY="$HOME/.mussels/install/host-static/lib/libcheck.a" ``` Set CPACK_PACKAGING_INSTALL_PREFIX to customize the resulting package's install location. This can be different than the install prefix. E.g.: ```sh -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CPACK_PACKAGING_INSTALL_PREFIX="/usr/local/clamav" \ ``` Then `make` and then one of these, depending on the platform: ```sh cpack # macOS: productbuild is default cpack -G DEB # Debian-based cpack -G RPM # RPM-based ``` On macOS you'll need to `pip3 install markdown` so that the NEWS.md file can be converted to html so it will render in the installer. On RPM-based systems, you'll need rpmbuild (install rpm-build) This commit also fixes an issue where the html manual (if present) was not correctly added to the Windows (or now other) install packages.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav).

GitHub Actions testing on Ubuntu, Mac, & Windows Updates to fix issues in the CMake install instructions. Updates the README.md to indicate that CMake is now preferred Adds a GitHub Actions badge, Discord badge, and logo to the README.md. CMake: - Renamed ENABLE_DOCS to ENABLE_MAN_PAGES. - Fixed build issue when milter isn't enabled on Linux. Changed the default to build milter on non-macOS, non-Windows operating systems. - Fix LD_LIBRARY_PATH for tests including on macOS where LD_LIBRARY_PATH and DYLD_LIBRARY_PATH must be manually propagated to subprocesses. - Use UNKNOWN IMPORTED library instead of INTERFACE IMPORTED library for pdcurses, but still use INTERFACE IMPORTED for ncurses. UNKNOWN IMPORTED appears to be required so that we can use $<TARGET_FILE_DIR:Curses::curses> to collected the pdcurses library at install time on Windows. - When building with vcpkg on Windows, CMake will automatically install your app local dependencies (aka the DLL runtime dependencies). Meanwhile, file(GET_RUNTIME_DEPENDENCIES ...) doesn't appear to work correctly with vcpkg packages. The solution is to use a custom target that has CMake perform a local install to the unit_tests directory when using vcpkg. This is in fact far easier than using GET_RUNTIME_DEPENDENCIES in the unit_tests for assembling the test environment but we can't use this method for the non-vcpkg install because it won't collect checkDynamic.dll for us because we don't install our tests. We also can't link with the static check.lib because the static check.lib has pthreads symbols linked in and will conflict with our pthread.dll. TL;DR: We'll continue to use file(GET_RUNTIME_DEPENDENCIES ...) for assembling the test enviornment on non-vcpkg builds, and use the local install method for vcpkg builds. testcase.py: Wrapped a Pathlib.unlink() call in exception handling as the missing_ok optional parameter requires a Python version too new for common use. Remove localtime_r from win32 compat lib. localtime_r may be present in libcheck when building with vcpkg and while making it a static function would also solve the issue, using localtime_s instead like we do everywhere else should work just fine. check_clamd: Limited the max # of connections for the stress test on Mac to 850, to address issues found testing on macos-latest on GitHub Actions.

CMake: Support external TomsFastMath library (libtfm) Add support for compiling with external TomsFastMath library provided by the system instead of compiling the vendored copy into libclamav. The vendored source is still built directly into libclamav instead of as a separate library the way libmspack is done. The rationale is that: A) it's more complicated to deal with possibly compiling as static or dynamic, and also B) libmspack and libunrar are compiled separately primarily because of licensing concerns. TomsFastMath public domain, so that isn't a concern. Resolves: https://bugzilla.clamav.net/show_bug.cgi?id=12562

Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter.

GitHub Actions testing on Ubuntu, Mac, & Windows Updates to fix issues in the CMake install instructions. Updates the README.md to indicate that CMake is now preferred Adds a GitHub Actions badge, Discord badge, and logo to the README.md. CMake: - Renamed ENABLE_DOCS to ENABLE_MAN_PAGES. - Fixed build issue when milter isn't enabled on Linux. Changed the default to build milter on non-macOS, non-Windows operating systems. - Fix LD_LIBRARY_PATH for tests including on macOS where LD_LIBRARY_PATH and DYLD_LIBRARY_PATH must be manually propagated to subprocesses. - Use UNKNOWN IMPORTED library instead of INTERFACE IMPORTED library for pdcurses, but still use INTERFACE IMPORTED for ncurses. UNKNOWN IMPORTED appears to be required so that we can use $<TARGET_FILE_DIR:Curses::curses> to collected the pdcurses library at install time on Windows. - When building with vcpkg on Windows, CMake will automatically install your app local dependencies (aka the DLL runtime dependencies). Meanwhile, file(GET_RUNTIME_DEPENDENCIES ...) doesn't appear to work correctly with vcpkg packages. The solution is to use a custom target that has CMake perform a local install to the unit_tests directory when using vcpkg. This is in fact far easier than using GET_RUNTIME_DEPENDENCIES in the unit_tests for assembling the test environment but we can't use this method for the non-vcpkg install because it won't collect checkDynamic.dll for us because we don't install our tests. We also can't link with the static check.lib because the static check.lib has pthreads symbols linked in and will conflict with our pthread.dll. TL;DR: We'll continue to use file(GET_RUNTIME_DEPENDENCIES ...) for assembling the test enviornment on non-vcpkg builds, and use the local install method for vcpkg builds. testcase.py: Wrapped a Pathlib.unlink() call in exception handling as the missing_ok optional parameter requires a Python version too new for common use. Remove localtime_r from win32 compat lib. localtime_r may be present in libcheck when building with vcpkg and while making it a static function would also solve the issue, using localtime_s instead like we do everywhere else should work just fine. check_clamd: Limited the max # of connections for the stress test on Mac to 850, to address issues found testing on macos-latest on GitHub Actions.

FIPS-compliant CVD signing and verification Add X509 certificate chain based signing with PKCS7-PEM external signatures distributed alongside CVD's in a custom .cvd.sign format. This new signing and verification mechanism is primarily in support of FIPS compliance. Fixes: https://github.com/Cisco-Talos/clamav/issues/564 Add a Rust implementation for parsing, verifying, and unpacking CVD files. Now installs a 'certs' directory in the app config directory (e.g. <prefix>/etc/certs). The install location is configurable. The CMake option to configure the CVD certs directory is: `-D CVD_CERTS_DIRECTORY=PATH` New options to set an alternative CVD certs directory: - Commandline for freshclam, clamd, clamscan, and sigtool is: `--cvdcertsdir PATH` - Env variable for freshclam, clamd, clamscan, and sigtool is: `CVD_CERTS_DIR` - Config option for freshclam and clamd is: `CVDCertsDirectory PATH` Sigtool: - Add sign/verify commands. - Also verify CDIFF external digital signatures when applying CDIFFs. - Place commonly used commands at the top of --help string. - Fix up manpage. Freshclam: - Will try to download .sign files to verify CVDs and CDIFFs. - Fix an issue where making a CLD would only include the CFG file for daily and not if patching any other database. libclamav.so: - Bump version to 13:0:1 (aka 12.1.0). - Also remove libclamav.map versioning. Resolves: https://github.com/Cisco-Talos/clamav/issues/1304 - Add two new API's to the public clamav.h header: ```c extern cl_error_t cl_cvdverify_ex(const char *file, const char *certs_directory); extern cl_error_t cl_cvdunpack_ex(const char *file, const char *dir, bool dont_verify, const char *certs_directory); ``` The original `cl_cvdverify` and `cl_cvdunpack` are deprecated. - Add `cl_engine_field` enum option `CL_ENGINE_CVDCERTSDIR`. You may set this option with `cl_engine_set_str` and get it with `cl_engine_get_str`, to override the compiled in default CVD certs directory. libfreshclam.so: Bump version to 4:0:0 (aka 4.0.0). Add sigtool sign/verify tests and test certs. Make it so downloadFile doesn't throw a warning if the server doesn't have the .sign file. Replace use of md5-based FP signatures in the unit tests with sha256-based FP signatures because the md5 implementation used by Python may be disabled in FIPS mode. Fixes: https://github.com/Cisco-Talos/clamav/issues/1411 CMake: Add logic to enable the Rust openssl-sys / openssl-rs crates to build against the same OpenSSL library as is used for the C build. The Rust unit test application must also link directly with libcrypto and libssl. Fix some log messages with missing new lines. Fix missing environment variable notes in --help messages and manpages. Deconflict CONFDIR/DATADIR/CERTSDIR variable names that are defined in clamav-config.h.in for libclamav from variable that had the same name for use in clamav applications that use the optparser. The 'clamav-test' certs for the unit tests will live for 10 years. The 'clamav-beta.crt' public cert will only live for 120 days and will be replaced before the stable release with a production 'clamav.crt'.

CMake: Add CTest support to match Autotools checks An ENABLE_TESTS CMake option is provided so that users can disable testing if they don't want it. Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required. Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

GitHub Actions testing on Ubuntu, Mac, & Windows Updates to fix issues in the CMake install instructions. Updates the README.md to indicate that CMake is now preferred Adds a GitHub Actions badge, Discord badge, and logo to the README.md. CMake: - Renamed ENABLE_DOCS to ENABLE_MAN_PAGES. - Fixed build issue when milter isn't enabled on Linux. Changed the default to build milter on non-macOS, non-Windows operating systems. - Fix LD_LIBRARY_PATH for tests including on macOS where LD_LIBRARY_PATH and DYLD_LIBRARY_PATH must be manually propagated to subprocesses. - Use UNKNOWN IMPORTED library instead of INTERFACE IMPORTED library for pdcurses, but still use INTERFACE IMPORTED for ncurses. UNKNOWN IMPORTED appears to be required so that we can use $<TARGET_FILE_DIR:Curses::curses> to collected the pdcurses library at install time on Windows. - When building with vcpkg on Windows, CMake will automatically install your app local dependencies (aka the DLL runtime dependencies). Meanwhile, file(GET_RUNTIME_DEPENDENCIES ...) doesn't appear to work correctly with vcpkg packages. The solution is to use a custom target that has CMake perform a local install to the unit_tests directory when using vcpkg. This is in fact far easier than using GET_RUNTIME_DEPENDENCIES in the unit_tests for assembling the test environment but we can't use this method for the non-vcpkg install because it won't collect checkDynamic.dll for us because we don't install our tests. We also can't link with the static check.lib because the static check.lib has pthreads symbols linked in and will conflict with our pthread.dll. TL;DR: We'll continue to use file(GET_RUNTIME_DEPENDENCIES ...) for assembling the test enviornment on non-vcpkg builds, and use the local install method for vcpkg builds. testcase.py: Wrapped a Pathlib.unlink() call in exception handling as the missing_ok optional parameter requires a Python version too new for common use. Remove localtime_r from win32 compat lib. localtime_r may be present in libcheck when building with vcpkg and while making it a static function would also solve the issue, using localtime_s instead like we do everywhere else should work just fine. check_clamd: Limited the max # of connections for the stress test on Mac to 850, to address issues found testing on macos-latest on GitHub Actions.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

CMake: Support to build deb, rpm, & macOS pkg packages CMake/CPack is already used to build: - TGZ source tarball - WiX-based installer (Windows) - ZIP install packages (Windows) This commit adds support for building: - macOS PKG installer - DEB package - RPM package This should also enable building FreeBSD packages, but while I was able to build all of the static dependencies using Mussels, CMake/CPack 3.20 doesn't appear to have the the FreeBSD generator despite being in the documentation. The package names are will be in this format: clamav-<version><suffix>.<os>.<arch>.<extension> This includes changing the Windows .zip and .msi installer names. E.g.: - clamav-0.104.0-rc.macos.x86_64.pkg - clamav-0.104.0-rc.win.win32.msi - clamav-0.104.0-rc.win.win32.zip - clamav-0.104.0-rc.win.x64.msi - clamav-0.104.0-rc.linux.x86_64.deb - clamav-0.104.0-rc.linux.x86_64.rpm Notes about building the packages: I've only tested this with building ClamAV using static dependencies that I build using the clamav_deps "host-static" recipes from the "clamav" Mussels cookbook. Eg: msl build clamav_deps -t host-static Here's an example configuration to build clam in this way, installing to /usr/local/clamav: ```sh cmake .. \ -D CMAKE_FIND_PACKAGE_PREFER_CONFIG=TRUE \ -D CMAKE_PREFIX_PATH=$HOME/.mussels/install/host-static \ -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CMAKE_MODULE_PATH=$HOME/.mussels/install/host-static/lib/cmake \ -D CMAKE_BUILD_TYPE=RelWithDebInfo \ -D ENABLE_EXAMPLES=OFF \ -D JSONC_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/json-c" \ -D JSONC_LIBRARY="$HOME/.mussels/install/host-static/lib/libjson-c.a" \ -D ENABLE_JSON_SHARED=OFF \ -D BZIP2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D BZIP2_LIBRARY_RELEASE="$HOME/.mussels/install/host-static/lib/libbz2_static.a" \ -D OPENSSL_ROOT_DIR="$HOME/.mussels/install/host-static" \ -D OPENSSL_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D OPENSSL_CRYPTO_LIBRARY="$HOME/.mussels/install/host-static/lib/libcrypto.a" \ -D OPENSSL_SSL_LIBRARY="$HOME/.mussels/install/host-static/lib/libssl.a" \ -D LIBXML2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include/libxml2" \ -D LIBXML2_LIBRARY="$HOME/.mussels/install/host-static/lib/libxml2.a" \ -D PCRE2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D PCRE2_LIBRARY="$HOME/.mussels/install/host-static/lib/libpcre2-8.a" \ -D CURSES_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D CURSES_LIBRARY="$HOME/.mussels/install/host-static/lib/libncurses.a" \ -D ZLIB_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D ZLIB_LIBRARY="$HOME/.mussels/install/host-static/lib/libz.a" \ -D LIBCHECK_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \ -D LIBCHECK_LIBRARY="$HOME/.mussels/install/host-static/lib/libcheck.a" ``` Set CPACK_PACKAGING_INSTALL_PREFIX to customize the resulting package's install location. This can be different than the install prefix. E.g.: ```sh -D CMAKE_INSTALL_PREFIX="/usr/local/clamav" \ -D CPACK_PACKAGING_INSTALL_PREFIX="/usr/local/clamav" \ ``` Then `make` and then one of these, depending on the platform: ```sh cpack # macOS: productbuild is default cpack -G DEB # Debian-based cpack -G RPM # RPM-based ``` On macOS you'll need to `pip3 install markdown` so that the NEWS.md file can be converted to html so it will render in the installer. On RPM-based systems, you'll need rpmbuild (install rpm-build) This commit also fixes an issue where the html manual (if present) was not correctly added to the Windows (or now other) install packages.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav).

CMake: Add CTest support to match Autotools checks An ENABLE_TESTS CMake option is provided so that users can disable testing if they don't want it. Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required. Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

Changed the hash table data integer type from long, which is poorly defined, to size_t -- which is capable of storing a pointer. Fixed a bunch of casts regarding this variable to eliminate warnings. Fixed two bugs causing utf8 encoding unit tests to fail on Windows: - The in_size variable should be the number of bytes, not the character count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8 transcoding test to only transcode half the bytes. - It turns out that the MultiByteToWideChar() API can't transcode UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer and flip the bytes on each uint16_t. This but was causing the UTF16-BE to UTF8 tests to fail. I also split up the utf8 transcoding tests into separate tests so I could see all of the failures instead of just the first one. Added a flags parameter to the unit test function to open testfiles because it turns out that on Windows if a file contains the \r\n it will replace it with just \n if you opened the file as a text file instead of as binary. However, if we open the CBC files as binary, then a bunch of bytecode tests fail. So I've changed the tests to open the CBC files in the bytecode tests as text files and open all other files as binary. Ported the feature tests from shell scripts to Python using a modified version of our QA test-framework, which is largely compatible and will allow us to migrate some QA tests into this repo. I'd like to add GitHub Actions pipelines in the future so that all public PR's get some testing before anyone has to manually review them. The clamd --log option was missing from the help string, though it definitely works. I've added it in this commit. It appears that clamd.c was never clang-format'd, so this commit also reformats clamd.c. Some of the check_clamd tests expected the path returned by clamd to match character for character with original path sent to clamd. However, as we now evaluate real paths before a scan, the path returned by clamd isn't going to match the relative (and possibly symlink-ridden) path passed to clamdscan. I fixed this test by changing the test to search for the basename: <signature> FOUND within the response instead of matching the exact path. Autotools: Link check_clamd with libclamav so we can use our utility functions in check_clamd.c.

tests: Use correct pytest command If pytest is available in the path, but wasn't found in the Python 3 installation discovered by CMake, then the test suite will fail. This can happen when two different Python 3 installations exist, eg 3.6 and 3.7 and when the newest one (prefered by CMake) doesn't have pytest. This commit will use the correct command depending on where pytest was (or wasn't) found. It will also fail more gracefully if neither pytest nor unittest was found (this happens with some wierd python installs).

CMake: Add CTest support to match Autotools checks An ENABLE_TESTS CMake option is provided so that users can disable testing if they don't want it. Instructions for how to use this included in the INSTALL.cmake.md file. If you run `ctest`, each testcase will write out a log file to the <build>/unit_tests directory. As with Autotools' make check, the test files are from test/.split and unit_tests/.split files, but for CMake these are generated at build time instead of at test time. On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled libraries can be loaded when running tests. On Windows systems, CTest will identify and collect all library dependencies and assemble a temporarily install under the build/unit_tests directory so that the libraries can be loaded when running tests. The same feature is used on Windows when using CMake to install to collect all DLL dependencies so that users don't have to install them manually afterwards. Each of the CTest tests are run using a custom wrapper around Python's unittest framework, which is also responsible for finding and inserting valgrind into the valgrind tests on Posix systems. Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by default, if Valgrind can be found. There's no need to set VG=1. CTest's memcheck module is NOT supported, because we use Python to orchestrate our tests. Added a bunch of Windows compatibility changes to the unit tests. These were primarily changing / to PATHSEP and making adjustments to use Win32 C headers and ifdef out the POSIX ones which aren't available on Windows. Also disabled a bunch of tests on Win32 that don't work on Windows, notably the mmap ones and FD-passing (i.e. FILEDES) ones. Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate warnings on Windows where json.h is included after inttypes.h because json-c's inttypes replacement relies on it. This is a it of a hack and may be removed if json-c fixes their inttypes header stuff in the future. Add preprocessor definitions on Windows to disable MSVC warnings about CRT secure and nonstandard functions. While there may be a better solution, this is needed to be able to see other more serious warnings. Add missing file comment block and copyright statement for clamsubmit.c. Also change json-c/json.h include filename to json.h in clamsubmit.c. The directory name is not required.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav).

As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

CMake: Add fuzz support. Enabled the metadata collection feature, scan heuristics, and all-match mode when fuzzing in the interest of better code coverage. Also remove deprecated STREAM command.

Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code.
