Do you have a symbolic link in /var/ that mount is trying to read? Ah. Yes. Forgot about that. mrepo -> /var/lib/libvirt/boot/ All isos in one place. You can add the rule using audit2allow. # grep var /var/log/audit/audit.log | audit2allow -M mymrepo # semodule -i mymrepo.pp |
There is a bug in the mrepo init script that prevents it from working. See bug You need to comment out the first line in the start() function: start() { # [ -x $exec ] || exit 5 Once that works, mrepo fails to start in enforcing mode. The following avc is given: type=AVC msg=audit(1273309126.732:319): avc: denied { read } for pid=1371 comm="mount" name="mrepo" dev=dm-2 ino=6347 scontext=unconfined_u:system_r:mount_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=lnk_file type=SYSCALL msg=audit(1273309126.732:319): arch=c000003e syscall=4 success=no exit=-13 a0=7fffee7b692c a1=7fffee7b45f0 a2=7fffee7b45f0 a3=7fffee7b4370 items=0 ppid=1370 pid=1371 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts1 ses=1 comm="mount" exe="/bin/mount" subj=unconfined_u:system_r:mount_t:s0 key=(null) type=AVC msg=audit(1273309126.732:320): avc: denied { read } for pid=1371 comm="mount" name="mrepo" dev=dm-2 ino=6347 scontext=unconfined_u:system_r:mount_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=lnk_file type=SYSCALL msg=audit(1273309126.732:320): arch=c000003e syscall=89 success=no exit=-13 a0=7fffee7b2550 a1=7fffee7b3560 a2=1000 a3=7fffee7b22b0 items=0 ppid=1370 pid=1371 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts1 ses=1 comm="mount" exe="/bin/mount" subj=unconfined_u:system_r:mount_t:s0 key=(null) type=AVC msg=audit(1273309126.733:321): avc: denied { read } for pid=1371 comm="mount" name="mrepo" dev=dm-2 ino=6347 scontext=unconfined_u:system_r:mount_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=lnk_file type=SYSCALL msg=audit(1273309126.733:321): arch=c000003e syscall=2 success=no exit=-13 a0=7f2d2af41880 a1=0 a2=7f2d2a365538 a3=7fffee7b3eb0 items=0 ppid=1370 pid=1371 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts1 ses=1 comm="mount" exe="/bin/mount" subj=unconfined_u:system_r:mount_t:s0 key=(null) -rwxr-xr-x. root root system_u:object_r:initrc_exec_t:s0 /etc/init.d/mrepo
