2020-04-04 bugfix: sigprocmask invocation on non-signalfd systemsLaurent Bercot
2020-02-26 Explicitly unblock signals when selfpiped without signalfdLaurent Bercot
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.
