Subject: [PATCH 0/2] coredump: Allow io_uring using apps to dump to pipes.
Date: Wed, 20 Jul 2022 11:49:31 -0500 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]> (Jens Axboe's message of "Tue, 31 May 2022 21:15:57 -0600")
Folks who have been suffering from io_uring coredumping issues please
give this a spin. I have lightly tested this version and more heavily
tested an earlier version which had more dependencies.
Unless I have missed something in cleaning up the code this should
be a comprehensive fix to the coredumping issues when using io_uring.
But folks please test and verify this. It has taken me long enough to
get back to this point I don't properly remember how the reproducer I
have was supposed to fail. All I can say with certainty is set of
changes has what looks like a positive effect.
Eric W. Biederman (2):
signal: Move stopping for the coredump from do_exit into get_signal
coredump: Allow coredumps to pipes to work with io_uring
