Since it is running as the login session I would figure the pam_afs_session is launching klog wihci is reading /etc/openafs/ThisCell 26418440f4bf110d3cf2ced1e9b561653934ff5b and commit ad4c99c4214f13fad48c019aa6c00340bb0e35b8 Fix this in git. Back ported. This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle. Changing version to '20'.

This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: I use "aklog" manually on this box, as well as using pam_afs_session. I'm not sure which tool (aklog on the commandline, or pam_afs_session) caused this AVC denial. SELinux is preventing /usr/bin/aklog from 'getattr' accesses on the file /etc/openafs/ThisCell. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that aklog should be allowed getattr access on the ThisCell 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 aklog /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:afs_config_t:s0 Target Objects /etc/openafs/ThisCell [ file ] Source aklog Source Path /usr/bin/aklog Port <Unknown> Host (removed) Source RPM Packages openafs-1.6.4-1.fc20.x86_64 Target RPM Packages openafs-client-1.6.4-1.fc20.x86_64 Policy RPM selinux-policy-3.12.1-66.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.10.3-300.fc19.x86_64 #1 SMP Fri Jul 26 00:00:58 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-08-07 12:06:31 EDT Last Seen 2013-08-07 12:06:31 EDT Local ID df6855a3-9f39-4d5f-a62c-d6d718700bee Raw Audit Messages type=AVC msg=audit(1375891591.558:575): avc: denied { getattr } for pid=1828 comm="aklog" path="/etc/openafs/ThisCell" dev="dm-0" ino=672536 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:afs_config_t:s0 tclass=file type=SYSCALL msg=audit(1375891591.558:575): arch=x86_64 syscall=fstat success=yes exit=0 a0=3 a1=7fff8e11e830 a2=7fff8e11e830 a3=0 items=0 ppid=1823 pid=1828 auid=4294967295 uid=42 gid=42 euid=42 suid=42 fsuid=42 egid=42 sgid=42 fsgid=42 ses=4294967295 tty=(none) comm=aklog exe=/usr/bin/aklog subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 key=(null) Hash: aklog,xdm_t,afs_config_t,file,getattr Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.10.3-300.fc19.x86_64 type: libreport
