Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information.

Implement basic sys$kill() and add a /bin/kill All it can do right now is send SIGKILL which just murders the target task.

LibC: Add most of the "header may make visible" dependencies from POSIX

Kernel+LibC: Share definitions for signal.h
2021-08-14 17:05:53 +02:00
#include <Kernel/API/POSIX/signal.h>
Kernel: Add support for SA_SIGINFO We currently don't really populate most of the fields, but that can wait :^)
2022-02-26 00:58:06 +03:30
#include <Kernel/API/POSIX/ucontext.h>
LibC: Move SIG_* definitions for sigprocmask into bits/sighow.h
2021-08-14 00:30:53 +02:00
#include <bits/sighow.h>
LibC: Add missing sys/cdefs.h include Some header files use __BEGIN_DECLS without including sys/cdefs.h. This causes issues for C code that compiles against these headers, which may occur with Ports.
2022-08-16 01:57:43 +10:00
#include <sys/cdefs.h>
Add clang-format file Also run it across the whole tree to get everything using the One True Style. We don't yet run this in an automated fashion as it's a little slow, but there is a snippet to do so in makeall.sh.

A bunch of LibC boilerplate stuff added while trying to get figlet to build.

int kill(pid_t, int sig);
A bunch of compat work (mostly stubs but some real implementations, too.) Another pass at getting bash-1.14.7 to build. Not that many symbols remain.
2018-11-11 00:20:53 +01:00
int killpg(int pgrp, int sig);
More random compat hacking towards getting bash to build. I'm now at the build stage where it complains about a bajillion missing symbols. This is a good place to be!

sighandler_t signal(int sig, sighandler_t);
Everywhere: Run clang-format
2022-04-01 20:58:27 +03:00
int pthread_sigmask(int how, sigset_t const* set, sigset_t* old_set);
Add sigset_t helper functions to LibC.
2018-11-06 12:02:58 +01:00
int sigaction(int sig, const struct sigaction* act, struct sigaction* old_act);
int sigemptyset(sigset_t*);
int sigfillset(sigset_t*);
int sigaddset(sigset_t*, int sig);
Everywhere: Run clang-format
2022-04-01 20:58:27 +03:00
int sigaltstack(stack_t const* ss, stack_t* old_ss);
Add sigset_t helper functions to LibC.
2018-11-06 12:02:58 +01:00
int sigdelset(sigset_t*, int sig);
LibC: Implement siginterrupt() This is just a simple wrapper around the more-modern sigaction.
2023-12-25 15:43:56 +02:00
int siginterrupt(int sig, int flag);
Everywhere: Run clang-format
2022-04-01 20:58:27 +03:00
int sigismember(sigset_t const*, int sig);
int sigprocmask(int how, sigset_t const* set, sigset_t* old_set);
Some improvements to signals. - Add sigprocmask() and sigpending(). - Forked children inherit signal dispositions and masks. - Exec clears signal dispositions and masks.
2018-11-10 23:29:07 +01:00
int sigpending(sigset_t*);
Everywhere: Run clang-format
2022-04-01 20:58:27 +03:00
int sigsuspend(sigset_t const*);
Kernel+LibC: Implement sigtimedwait() This includes a new Thread::Blocker called SignalBlocker which blocks until a signal of a matching type is pending. The current Blocker implementation in the Kernel is very complicated, but cleaning it up is a different yak for a different day.
2021-12-12 01:01:42 +02:00
int sigtimedwait(sigset_t const*, siginfo_t*, struct timespec const*);
LibC: Implement sigwait() This is done internally by just calling the more modern sigtimedwait syscall and then massaging the results to fit sigwait's interface.
2021-12-11 21:21:47 +02:00
int sigwait(sigset_t const*, int*);
LibC: Implement sigwaitinfo() This is implemented as a simple wrapper around sigtimedwait()
2021-12-12 01:02:08 +02:00
int sigwaitinfo(sigset_t const*, siginfo_t*);
LibC: Enough compat work to make binutils-2.32 build and run.
2019-02-23 17:24:50 +01:00
int raise(int sig);
Everywhere: Run clang-format
