*	sighook: Return instead of re-raising for faults	Tavian Barnes	2024-11-23	1	-5/+11
\| \| \| \| \| \| \| \| \| \| \|	This makes the death look exactly like it would if we didn't handle the signal at all. Coredumps will point at the right instruction, segfaults will get logged in dmesg again, etc. Technically POSIX says this is undefined, but if we get a fault, we've already done something undefined anyway ;) Link: https://github.com/rust-lang/rust/issues/26458
*	sighook: Check for SA_RESTART before using it	Tavian Barnes	2024-11-23	1	-1/+7
\| \| \| \|	QNX doesn't support SA_RESTART.
*	sighook: Don't forget to reset list->tail on the last sigpop()	Tavian Barnes	2024-10-10	1	-0/+2
\| \| \| \| \| \| \|	This was causing a UAF if we ever unregistered the last hook for a signal and then re-registered one. Fixes: 75b7f70 ("sighook: Make sigunhook() O(1)")
*	Fix includes	Tavian Barnes	2024-08-29	1	-0/+1

*	build: Move feature test macros to prelude.h	Tavian Barnes	2024-08-28	1	-1/+0
\| \| \| \| \| \|	This replaces the explicit CPPFLAGS list in flags.mk with just `-include src/prelude.h`, shortening our compiler command lines and allowing them to be easily documented.
*	prelude: Split bfs-specific utilities into new bfs.h header	Tavian Barnes	2024-08-28	1	-0/+3

*	sighook: Fix typo in comment	Tavian Barnes	2024-08-17	1	-1/+1

*	sighook: Disable semaphores on NetBSD	Tavian Barnes	2024-08-11	1	-1/+2

*	bfstd: New sysoption() macro to check for POSIX option runtime support	Tavian Barnes	2024-08-09	1	-7/+17
\| \| \| \| \| \| \| \| \| \|	POSIX allows optional features to be supported at compile time but not necessarily at run time by defining _POSIX_OPTION to 0 and requiring users to check sysconf(_SC_OPTION) > 0. The new sysoption() macro simplifies the check. sighook() and bfs_spawn() now check for conditional runtime support for the relevant POSIX options.

*	sighook: Replace sigtables with RCU-protected linked lists	Tavian Barnes	2024-07-07	1	-148/+68
\| \| \| \| \| \| \| \|	This fixes an ABA problem where sigdispatch() could think no handlers are registered for a signal even when there are. Link: https://unix.stackexchange.com/a/779594/56202 Fixes: 375caac ("sighook: New utilities for hooking signals")
*	sighook: Shard the signal table	Tavian Barnes	2024-06-07	1	-7/+24
\|
*	sighook: Ignore sigaction() errors in atsigexit()	Tavian Barnes	2024-06-07	1	-10/+6
\| \| \| \|	This fixes bfs under Valgrind, which reserves SIGRTMAX for its own use.
*	sighook: Check that atomic size_t is lock-free	Tavian Barnes	2024-06-03	1	-0/+4
\|
*	sighook: Allow sigunhook(NULL)	Tavian Barnes	2024-05-25	1	-0/+4
\|
*	diag: New helpers to include xstrerror(errno) automatically	Tavian Barnes	2024-05-17	1	-2/+2
\|
*	sighook: New utilities for hooking signals	Tavian Barnes	2024-05-16	1	-0/+600
	This allows multiple hooks to be installed for a single signal.
