Subject: [PATCH 0/2] sigaltstack: remove EPERM check
Date: Sat, 9 Jan 2016 04:00:00 +0300	[thread overview]
Message-ID: <56905B90.6060505@list.ru> (raw)

The following patches add the self-test for
sigaltstack(SS_DISABLE) inside the signal handler,
and remove the EPERM check in a sigaltstack()
syscall.
This is needed to make sigaltstack() compatible with
swapcontext(): before using swapcontext() inside
the sighandler, the sigaltstack should be disabled, or
the stack will be corrupted by the subsequent signals.
