'restorecon -FR /lib/modules' has fixed the issue for me Ok, the question is how it got mislabeling. Is it a fresh install? The fresh install of F19 RC4 (that was subsequently declared beta) was fine, the problem occurred after I updated the system yesterday (with updates-testing enabled IIRC). I'll attach full yum.log for reference. Created attachment 754275 [details]
full yum.log
I guess the other question is there a reason they are labeled incorrectly. Rebuilding a kernel could cause the problem. Milos, AFAIK we had this issue on RHEL and we have reproducer for this? David, are you able to get it again? I didn't get it again on the same machine, should I try to reproduce with another one, including the installation of Beta and upgrade? Yes, please. Thank you. #============= iscsid_t ============== #!!!! This avc is allowed in the current policy allow iscsid_t modules_object_t:dir search; |
Description of problem: The problem occurs when iscsid is logging to a target. Discovery works OK. F19 Beta was not affected by this bug. SELinux is preventing /usr/sbin/iscsid from 'search' accesses on the directory /usr/lib/modules. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that iscsid should be allowed search access on the modules directory 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 iscsid /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:iscsid_t:s0 Target Context system_u:object_r:modules_object_t:s0 Target Objects /usr/lib/modules [ dir ] Source iscsid Source Path /usr/sbin/iscsid Port <Unknown> Host (removed) Source RPM Packages iscsi-initiator-utils-6.2.0.873-5.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-44.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.4-300.fc19.x86_64 #1 SMP Fri May 24 22:17:06 UTC 2013 x86_64 x86_64 Alert Count 7 First Seen 2013-05-28 11:28:17 CEST Last Seen 2013-05-28 12:05:31 CEST Local ID 261d9b42-ed9b-4728-91f2-7e44b5ec6773 Raw Audit Messages type=AVC msg=audit(1369735531.305:591): avc: denied { search } for pid=3221 comm="iscsid" name="modules" dev="dm-0" ino=538740 scontext=system_u:system_r:iscsid_t:s0 tcontext=system_u:object_r:modules_object_t:s0 tclass=dir type=SYSCALL msg=audit(1369735531.305:591): arch=x86_64 syscall=open success=no exit=EACCES a0=7fffbec30ea0 a1=80000 a2=1b6 a3=0 items=0 ppid=1 pid=3221 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=iscsid exe=/usr/sbin/iscsid subj=system_u:system_r:iscsid_t:s0 key=(null) Hash: iscsid,iscsid_t,modules_object_t,dir,search Additional info: reporter: libreport-2.1.4 hashmarkername: setroubleshoot kernel: 3.9.4-300.fc19.x86_64 type: libreport
