Description Karel Srot 2020-10-22 10:06:12 UTC

Description of problem:

I have accidentally provided wrong module file. After that p11-kit got stuck. And not just p11-kit itself but also other utilities using it.

Version-Release number of selected component (if applicable):
p11-kit-0.23.14-5.el8_0.x86_64

How reproducible:
always

Steps to Reproduce:
# echo 'module:' > /usr/share/p11-kit/modules/test.module
# p11-kit list-modules

Actual results:
p11-kit command got stuck. And not just p11-kit cmd but also subsequent calls like modutil got stuck since they interact with p11-kit (through proxy?)
no error reported in logs

Expected results:
error on stderr, error logged in /var/log/messages
non-critical module could be probably ignored/skipped
