Description of problem: SELinux is preventing /usr/bin/kdm from using the 'signull' accesses on a process. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that kdm should be allowed signull access on processes labeled remote_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 kdm /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:system_r:remote_login_t:s0 Target Objects [ process ] Source kdm Source Path /usr/bin/kdm Port <Unknown> Host (removed) Source RPM Packages kdm-4.11.7-1.fc20.i686 Target RPM Packages Policy RPM selinux-policy-3.12.1-135.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.13.6-200.fc20.i686 #1 SMP Fri Mar 7 17:28:21 UTC 2014 i686 i686 Alert Count 2 First Seen 2014-03-26 16:22:08 IST Last Seen 2014-03-26 16:45:54 IST Local ID 1abd89b5-21b1-4707-be6a-e32993d63a76 Raw Audit Messages type=AVC msg=audit(1395832554.572:482): avc: denied { signull } for pid=680 comm="kdm" scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:system_r:remote_login_t:s0 tclass=process type=SYSCALL msg=audit(1395832554.572:482): arch=i386 syscall=kill success=no exit=EACCES a0=5d65 a1=0 a2=b77c5bd8 a3=b80f7378 items=0 ppid=1 pid=680 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=kdm exe=/usr/bin/kdm subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 key=(null) Hash: kdm,xdm_t,remote_login_t,process,signull Additional info: reporter: libreport-2.2.0 hashmarkername: setroubleshoot kernel: 3.13.6-200.fc20.i686 type: libreport
