Description of problem: Using screen normally. Didn't correlate it to any particular action. SELinux is preventing /usr/bin/screen from using the 'sigchld' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that screen should be allowed sigchld access on processes labeled staff_screen_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 screen /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context staff_u:staff_r:irc_t:s0-s0:c0.c1023 Target Context staff_u:staff_r:staff_screen_t:s0-s0:c0.c1023 Target Objects [ process ] Source screen Source Path /usr/bin/screen Port <Unknown> Host (removed) Source RPM Packages screen-4.1.0-0.14.20120314git3c2946.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-54.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.8-300.fc19.x86_64 #1 SMP Thu Jun 27 19:24:23 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-07-02 16:38:39 EDT Last Seen 2013-07-02 16:38:39 EDT Local ID 92dc3fb2-e13c-4121-9751-8eee2b959f35 Raw Audit Messages type=AVC msg=audit(1372797519.46:446): avc: denied { sigchld } for pid=2702 comm="screen" scontext=staff_u:staff_r:irc_t:s0-s0:c0.c1023 tcontext=staff_u:staff_r:staff_screen_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1372797519.46:446): arch=x86_64 syscall=wait4 success=yes exit=0 a0=ffffffffffffffff a1=7fff1618ba30 a2=3 a3=0 items=0 ppid=2358 pid=2702 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=84 sgid=84 fsgid=84 ses=1 tty=(none) comm=screen exe=/usr/bin/screen subj=staff_u:staff_r:staff_screen_t:s0-s0:c0.c1023 key=(null) Hash: screen,irc_t,staff_screen_t,process,sigchld Additional info: reporter: libreport-2.1.5 hashmarkername: setroubleshoot kernel: 3.9.8-300.fc19.x86_64 type: libreport
