Subject: [PATCH 0/2]: Fixing unkillable processes caused by SIGHUP timers
Date: Thu, 07 Feb 2019 00:42:45 -0600 [thread overview]
Message-ID: <875ztwt7yy.fsf_-_@xmission.com> (raw)
In-Reply-To: <87imxwv9jp.fsf@xmission.com> (Eric W. Biederman's message of "Wed, 06 Feb 2019 16:25:46 -0600")
Dmitry,
Can you please verify the follow two patches. The first one is a
simplification of the one you have already tested and makes the
processes killable. The second patch improves our heuristic for
detecting synchronous like SIGSEGV when the stack overflows allowing us
to process them before SIGHUP.
Eric W. Biederman (2):
signal: Always notice exiting tasks
signal: Better detection of synchronous signals
