Description of problem: SELinux is preventing /usr/bin/who from using the 'signull' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that who should be allowed signull access on processes labeled local_login_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 who /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:fsdaemon_t:s0 Target Context system_u:system_r:local_login_t:s0-s0:c0.c1023 Target Objects [ process ] Source who Source Path /usr/bin/who Port <Unknown> Host (removed) Source RPM Packages coreutils-8.17-8.fc18.i686 Target RPM Packages Policy RPM selinux-policy-3.11.1-86.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.8.5-201.fc18.i686 #1 SMP Thu Mar 28 21:59:40 UTC 2013 i686 i686 Alert Count 1 First Seen 2013-04-05 20:57:37 IRDT Last Seen 2013-04-05 20:57:37 IRDT Local ID 59945eef-2bd3-4a54-9c37-6e71dea021e8 Raw Audit Messages type=AVC msg=audit(1365179257.244:867): avc: denied { signull } for pid=30777 comm="who" scontext=system_u:system_r:fsdaemon_t:s0 tcontext=system_u:system_r:local_login_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1365179257.244:867): arch=i386 syscall=kill success=no exit=EACCES a0=77c6 a1=0 a2=8055000 a3=92e1860 items=0 ppid=30776 pid=30777 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=who exe=/usr/bin/who subj=system_u:system_r:fsdaemon_t:s0 key=(null) Hash: who,fsdaemon_t,local_login_t,process,signull audit2allow #============= fsdaemon_t ============== allow fsdaemon_t local_login_t:process signull; audit2allow -R require { type fsdaemon_t; } #============= fsdaemon_t ============== locallogin_signull(fsdaemon_t) Additional info: hashmarkername: setroubleshoot kernel: 3.8.5-201.fc18.i686 type: libreport Potential duplicate: bug 837723
