Better NSIG detection and fix

2022-09-05T06:59:43Z

Incredibly enough, OpenBSD defines NSIG correctly, so our workaround was not accurate. Signed-off-by: Laurent Bercot

Huge incompatible changes.

2021-07-28T23:45:20Z

- Obsolete skalibs/environ.h and skalibs/getpeereid.h removed. - rc4 and md5 removed. - All *_t types renamed to avoid treading on POSIX namespace. - subgetopt() renamed to lgetopt(). - signal functions reworked; skasigaction removed; sig_stack removed - Various functions removed: skaoffsetof(), selfpipe_untrap() - New posixplz function: munmap_void.

Explicitly unblock signals when selfpiped without signalfd

2020-02-26T17:18:47Z

This is arguably a bugfix, since selfpipe without signalfd relies on signals being actually delivered, and a process may have inherited a nonempty sigprocmask. Also use SIG_BLOCK instead of SIG_SETMASK when using selfpipe_trapset() with signalfd, because we shouldn't unblock signals that may have previously been blocked. This is also arguably a bugfix. This commit is essential for using the version of s6-linux-init that blocks SIGINT before disablecad on kernels without signalfd. Without it, SIGINT never gets unblocked, so it's never delivered to s6-svscan.

Change SKALIBS_NSIG to SKALIBS_DEFAULT_NSIG and NSIG to SKALIBS_NSIG to accommodate OpenBSD snowflakiness

Always pair skalibs/nsig.h with skalibs/nonposix.h (and screw NSIG with a chainsaw)

2017-04-28T11:16:35Z

Fix NSIG definition (max+1 instead of max)

2017-04-28T10:35:45Z

Types change: big pass on libstddjb and libunixonacid
