Description of problem: Just appeared on boot of today's F22. SELinux is preventing /usr/sbin/load_policy from 'write' accesses on the fifo_file fifo_file. ***** Plugin leaks (86.2 confidence) suggests ***************************** If you want to ignore load_policy trying to write access the fifo_file fifo_file, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do # grep /usr/sbin/load_policy /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (14.7 confidence) suggests ************************** If you believe that load_policy should be allowed write access on the fifo_file fifo_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 load_policy /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:load_policy_t:s0 Target Context system_u:system_r:sssd_t:s0 Target Objects fifo_file [ fifo_file ] Source load_policy Source Path /usr/sbin/load_policy Port <Unknown> Host (removed) Source RPM Packages policycoreutils-2.3-15.fc22.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-112.fc22.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.20.0-0.rc0.git7.2.fc23.x86_64 #1 SMP Tue Feb 17 16:52:19 UTC 2015 x86_64 x86_64 Alert Count 202 First Seen 2015-01-12 18:00:28 PST Last Seen 2015-02-19 14:46:47 PST Local ID 4d17b490-bad0-4067-9a83-5d990b617cac Raw Audit Messages type=AVC msg=audit(1424386007.808:728): avc: denied { write } for pid=3481 comm="load_policy" path="pipe:[61012]" dev="pipefs" ino=61012 scontext=system_u:system_r:load_policy_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=fifo_file permissive=0 type=AVC msg=audit(1424386007.808:728): avc: denied { read } for pid=3481 comm="load_policy" path="pipe:[16122]" dev="pipefs" ino=16122 scontext=system_u:system_r:load_policy_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=fifo_file permissive=0 type=AVC msg=audit(1424386007.808:728): avc: denied { write } for pid=3481 comm="load_policy" path="pipe:[16122]" dev="pipefs" ino=16122 scontext=system_u:system_r:load_policy_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=fifo_file permissive=0 type=AVC msg=audit(1424386007.808:728): avc: denied { read } for pid=3481 comm="load_policy" path="pipe:[18162]" dev="pipefs" ino=18162 scontext=system_u:system_r:load_policy_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=fifo_file permissive=0 type=AVC msg=audit(1424386007.808:728): avc: denied { write } for pid=3481 comm="load_policy" path="pipe:[18162]" dev="pipefs" ino=18162 scontext=system_u:system_r:load_policy_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=fifo_file permissive=0 type=AVC msg=audit(1424386007.808:728): avc: denied { write } for pid=3481 comm="load_policy" path="pipe:[61012]" dev="pipefs" ino=61012 scontext=system_u:system_r:load_policy_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=fifo_file permissive=0 type=AVC msg=audit(1424386007.808:728): avc: denied { read } for pid=3481 comm="load_policy" path="pipe:[61013]" dev="pipefs" ino=61013 scontext=system_u:system_r:load_policy_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=fifo_file permissive=0 type=SYSCALL msg=audit(1424386007.808:728): arch=x86_64 syscall=execve success=yes exit=0 a0=7f3758f53040 a1=7f3759c00de0 a2=0 a3=58c items=0 ppid=3480 pid=3481 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=load_policy exe=/usr/sbin/load_policy subj=system_u:system_r:load_policy_t:s0 key=(null) Hash: load_policy,load_policy_t,sssd_t,fifo_file,write Version-Release number of selected component: selinux-policy-3.13.1-112.fc22.noarch Additional info: reporter: libreport-2.3.0 hashmarkername: setroubleshoot kernel: 3.20.0-0.rc0.git7.2.fc23.x86_64 type: libreport Potential duplicate: bug 1185577
