The relevant packages would be: bind-9.8.0-5.P2.fc15.x86_64 bind-chroot-9.8.0-5.P2.fc15.x86_64 The relevant mount call is probably from /etc/init.d/named Is this bind mounting from the real rndc.key? Fixed in selinux-policy-3.9.16-30.fc15 (In reply to comment #2) > Is this bind mounting from the real rndc.key?

SELinux is preventing /bin/mount from 'mounton' accesses on the arquivo /var/named/chroot/etc/rndc.key. ***** Plugin mounton (91.4 confidence) suggests **************************** If you want to allow mount to mount on rndc.key. Then you must change the labeling on /var/named/chroot/etc/rndc.key. Do # semanage fcontext -a -t mnt_t '/var/named/chroot/etc/rndc.key' # restorecon -v /var/named/chroot/etc/rndc.key ***** Plugin catchall (9.59 confidence) suggests *************************** If you believe that mount should be allowed mounton access on the rndc.key 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: # grep mount /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:mount_t:s0 Target Context system_u:object_r:dnssec_t:s0 Target Objects /var/named/chroot/etc/rndc.key [ file ] Source mount Source Path /bin/mount Port <Desconhecido> Host (removed) Source RPM Packages util-linux-2.19.1-1.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-26.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.38.7-30.fc15.x86_64 #1 SMP Fri May 27 05:15:53 UTC 2011 x86_64 x86_64 Alert Count 4 First Seen Qua 15 Jun 2011 19:46:28 BRT Last Seen Qui 16 Jun 2011 21:01:25 BRT Local ID be61e7e0-aa30-4bf9-a6ac-855794cf8329 Raw Audit Messages type=AVC msg=audit(1308268885.471:205): avc: denied { mounton } for pid=8055 comm="mount" path="/var/named/chroot/etc/rndc.key" dev=dm-2 ino=233370 scontext=system_u:system_r:mount_t:s0 tcontext=system_u:object_r:dnssec_t:s0 tclass=file type=SYSCALL msg=audit(1308268885.471:205): arch=x86_64 syscall=mount success=no exit=EACCES a0=7f8094538630 a1=7f8094545910 a2=7f8093183eef a3=ffffffffc0ed1001 items=0 ppid=8035 pid=8055 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=mount exe=/bin/mount subj=system_u:system_r:mount_t:s0 key=(null) Hash: mount,mount_t,dnssec_t,file,mounton audit2allow #============= mount_t ============== allow mount_t dnssec_t:file mounton; audit2allow -R #============= mount_t ============== allow mount_t dnssec_t:file mounton;
