SELinux is preventing /usr/sbin/postdrop from write access on the fifo_file fifo_file. ***** Plugin leaks (86.2 confidence) suggests ***************************** If you want to ignore postdrop 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/postdrop /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (14.7 confidence) suggests ************************** If you believe that postdrop 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 postdrop /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:postfix_postdrop_t:s0 Target Context system_u:system_r:postfix_master_t:s0 Target Objects fifo_file [ fifo_file ] Source postdrop Source Path /usr/sbin/postdrop Port <Unknown> Host server.interlinx.bc.ca Source RPM Packages postfix-2.10.1-6.el7.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-60.el7_2.9.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name server.interlinx.bc.ca Platform Linux server.interlinx.bc.ca 3.10.0-327.28.3.el7.x86_64 #1 SMP Thu Aug 18 19:05:49 UTC 2016 x86_64 x86_64 Alert Count 87 First Seen 2016-09-26 14:10:10 EDT Last Seen 2016-09-27 10:27:44 EDT Local ID 7d4f745a-0a10-4c8c-a27b-ca554bb5f271 Raw Audit Messages type=AVC msg=audit(1474986464.478:4114): avc: denied { write } for pid=17279 comm="postdrop" path="pipe:[27058]" dev="pipefs" ino=27058 scontext=system_u:system_r:postfix_postdrop_t:s0 tcontext=system_u:system_r:postfix_master_t:s0 tclass=fifo_file Hash: postdrop,postfix_postdrop_t,postfix_master_t,fifo_file,write This seems to be the EL7 version of bug #828739.
