[pkg-cryptsetup-devel] Bug#1034767: cryptsetup: askpass goes to 100% CPU utilisation when it's terminal HUPs

[Christoph Anton Mitterer]

Package: cryptsetup
Version: 2:2.6.1-4
Severity: normal


Hey.

When askpass is running (and waiting) while it's terminal gets somehow
killed/HUPed/etc. ... it's process goes to 100% utilisation from where
it doesn't seem to recover anymore.

Reproducer:
Shell 1:
	echo $$
	/lib/cryptsetup/askpass foo
Shell 2:
	kill -HUP <the $$ from Shell 1>


Haven't tried it yet, but perhaps my waiting-forever PR at:
   https://salsa.debian.org/cryptsetup-team/cryptsetup/-/merge_requests/26
might fix that ;-)


Cheers,
Chris.
