Created attachment 327637 [details] patch fixing problems described herein Description of problem: We've been doing IDS work and noticed that less is calling fsync on the tty device. This is unsupported and produces EINVAL return codes. How reproducible: always Steps to Reproduce: 1. add this to audit rules: -a always,exit -F fsync -F exit=-EINVAL -k einval 2. open a file with less 3. run ausearch --start recent -k einval Attaching a patch that fixes the problem by testing in autoconf if fsync produces EINVAL when called against the tty descriptor. This requires adding autoreconf to the build section.
