Description of problem: SELinux is preventing /usr/sbin/sshd from using the 'dyntransition' accesses on a process. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that sshd should be allowed dyntransition access on processes labeled unconfined_t 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 sshd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:initrc_t:s0 Target Context unconfined_u:unconfined_r:unconfined_t:s0 Target Objects [ process ] Source sshd Source Path /usr/sbin/sshd Port <Unknown> Host (removed) Source RPM Packages openssh-server-6.2p2-5.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-70.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.11.0-0.rc6.git0.2.fc20.x86_64 #1 SMP Mon Aug 19 14:58:14 UTC 2013 x86_64 x86_64 Alert Count 3 First Seen 2013-08-27 11:01:58 PDT Last Seen 2013-08-28 14:42:30 PDT Local ID 4101b7b5-5e57-4f2a-abc2-72c03e87ee72 Raw Audit Messages type=AVC msg=audit(1377726150.555:677): avc: denied { dyntransition } for pid=4710 comm="sshd" scontext=system_u:system_r:initrc_t:s0 tcontext=unconfined_u:unconfined_r:unconfined_t:s0 tclass=process type=SYSCALL msg=audit(1377726150.555:677): arch=x86_64 syscall=write success=no exit=EACCES a0=7 a1=7f5864365240 a2=2a a3=666e6f636e753a72 items=0 ppid=4689 pid=4710 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 ses=6 tty=(none) comm=sshd exe=/usr/sbin/sshd subj=system_u:system_r:initrc_t:s0 key=(null) Hash: sshd,initrc_t,unconfined_t,process,dyntransition Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.11.0-0.rc7.git1.2.fc21.x86_64 type: libreport
You sshd service running as initrc_t. Basically there is an issue with labeling after upgrade. You will need to fix labeling on your system # touch /.autorelabel # reboot to make sure all files/dirs are labeled correctly after boot. We have opened bug on this issue related to the yum component.
