This problem happens again in selinux-policy-targeted-1.21.3-6. ---- in dmesg [...] audit(1106839801.270:0): avc: denied { transition } for pid=3881 exe=/usr/sbin/crond path=/bin/bash dev=hda8 ino=926648 scontext=user_u:system_r:system_crond_t tcontext=system_u:system_r:unconfined_t tclass=process
I get the same here, with yesterday's rawhide, even after relabeling / (containing usr, var, etc, etc :-) and rebooting. I get hourly e-mails indicating permission denied to run /bin/bash or /bin/sh, with subjects such as: Cron <root@$host> run-parts /etc/cron.hourly Cron <root@$host> /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok Cron <root@$host> /usr/lib/sa/sa1 1 1 Quite annoying :-( I see there are special provisions for cron in crond.te, but I don't see any of them making to file_contexts or policy, is that intentional?
1.21.5-4 should fix that. Available now on ftp://people.redhat.com/dwalsh/SELinux/Fedora or tomorrow via Rawhide.
