Hi, Please have a look the bug This is not an audit problem. Transferring to selinux-policy. The second SELinux denial is already addressed in BZ#1932752. I rescheduled the beaker job mentioned in comment#0 and added one of selinux-policy TCs which deals with the fcoe service: If everything goes well, we will see complete SELinux denials. Hi Same question can be reproduced with RHEL8.4 please see https://bugzilla.redhat.com/show_bug.cgi?id=1918561#c22 I don't have access to machines with FCoE HW, which means that I cannot re-run the same tests in permissive mode. If this bug should be fixed completely, we need to see SELinux denials triggered by these tests when they are executed in permissive mode. Could you re-run the same commands as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1918561#c22 in permissive mode? # setenforce 0 # fcoeadm ... # fcoeadm ... # ausearch -m avc -m user_avc -m selinux_err -i -ts today Please attach the whole output from ausearch command to the bug report. hi

SELinux is preventing fcoemon from create access on the file enabled.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that fcoemon should be allowed create access on the enabled file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'fcoemon' --raw | audit2allow -M my-fcoemon
# semodule -X 300 -i my-fcoemon.pp

Allow fcoemon create sysfs files
This permission is required when fcoemon wants to write to the
/sys/bus/fcoe/devices/ctlr_X/enabled file and this file does not exist.
