Primarily this commit fixes an issue with the size of the parameters
passed to cli_checklimits(). The parameters were "unsigned long", which
varies in size depending on platform.
I've switched them to uint64_t / u64.
While working on this, I observed some concerning warnigns on Windows,
and some less serious ones, primarily regarding inconsistencies with
`const` parameters.
Finally, in `scanmem.c`, there is a warning regarding use of `wchar_t *`
with `GetModuleFileNameEx()` instead of `GetModuleFileNameExW()`.
This made me realize this code assumes we're not defining `UNICODE`,
which would have such macros use the 'A' variant.
I have fixed it the best I can, although I'm still a little
uncomfortable with some of this code that uses `char` or `wchar_t`
instead of TCHAR.
I also remove the `if (GetModuleFileNameEx) {` conditional, because this
macro/function will always be defined. The original code was checking a
function pointer, and so this was a bug when integrating into ClamAV.
Regarding the changes to `rijndael.c`, I found that this module assumes
`unsigned long` == 32bits. It does not.
I have corrected it to use `uint32_t`.
Coverity-344508: Fix out-of-bound read in check_str test.
The len argument cannot be longer than the size of the source buffer.
The original test was attempting to test an append failure.
The updated test checks for correct behavior with two consecutive
appends.
Also added function comments to document correct use of textbuffer
functions.
Coverity-344493: Fix out-of-bounds read in check_jsnorm test.
The buffers passed to tokenizer_test must be NULL-terminated.
This commit adds a feature to find, decode, and scan each image found
within HTML <style> tags where the image data is embedded in `url()`
function parameters a base64 blob
In C in the html normalization process we extract style tag contents
to new buffer for processing. We call into a new feature in Rust code to
find and decode each image (if there are multiple).
Once extracted, the images are scanned as contained files of unknown
type, and file type identifcation will determine the actual type.
On Windows, files open()'ed without the O_BINARY flag will have new-line
LF (aka \n) converted to CRLF (aka \r\n) automatically when read from or
written to. This is undesirable for all scan targets AND temp files
because it affects pattern matching and with hashing.
This commit converts a handful of instances throughout the codebase
where it appears that O_BINARY was mistakenly omitted and could result
in unexpected behavior on Windows.
Git on Windows also converts LF -> CRLF for "text" files, for editing
purposes.
This is problematic for scan files and test files that should match
verbatim.
We can prevent this issue by marking .ref test files as "binary" in the
.gitattributes file and by always opening scan files and temp files as
binary.
In this commit I've also removed the `ChangeLog merge=cl-merge` line
that was once used to reduce ChangeLog merge conflicts by using the
gnulib git-merge-changlog tool. This project now categorizes changes in
the NEWS.md.

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.
Tests in libcheck 0.13 must have {} between START_TEST and END_TEST
else it will not compile.
Also replaced all deprecated "fail_" macros with "ck_" macros.
E.g. fail_unless() becomes ck_assert_msg()
The checks_common.h header file provided a couple of macros to
support versions older than 0.9.3. As these older versions are
no longer relevant, I've removed those compatibility macros
entirely.
by skipping checks that require it. (bb #1157)
if configure is not able to find check, you can use
--with-libcheck-prefix, instead of CHECK_CFLAGS and
CHECK_LIBS.
