Any idea why nmbd would be trying to read this file? I just upgraded from F17 via F18, so it's a old config. A quick Google search seems to indicate that Samba scans all mounts on startup. Well this is not a mount it is an open.But I don't see a problem with allowing it to read it. commit c095f4d547287c5354c3db9dc0e6ea50c69dc0e6

Description of problem: SELinux is preventing /usr/sbin/nmbd from 'open' accesses on the file /proc/sys/kernel/core_pattern. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that nmbd should be allowed open access on the core_pattern 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 nmbd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:nmbd_t:s0 Target Context system_u:object_r:usermodehelper_t:s0 Target Objects /proc/sys/kernel/core_pattern [ file ] Source nmbd Source Path /usr/sbin/nmbd Port <Unknown> Host (removed) Source RPM Packages samba-4.1.9-3.fc21.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-63.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.16.0-0.rc4.git3.1.fc21.x86_64 #1 SMP Fri Jul 11 17:13:44 UTC 2014 x86_64 x86_64 Alert Count 1 First Seen 2014-07-15 19:59:55 CEST Last Seen 2014-07-15 19:59:55 CEST Local ID d54173d5-12e4-4262-a188-55fb8660109a Raw Audit Messages type=AVC msg=audit(1405447195.131:160): avc: denied { open } for pid=2334 comm="nmbd" path="/proc/sys/kernel/core_pattern" dev="proc" ino=10416 scontext=system_u:system_r:nmbd_t:s0 tcontext=system_u:object_r:usermodehelper_t:s0 tclass=file permissive=0 type=SYSCALL msg=audit(1405447195.131:160): arch=x86_64 syscall=open success=no exit=EACCES a0=7fb61a12de0a a1=0 a2=0 a3=0 items=0 ppid=1 pid=2334 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=nmbd exe=/usr/sbin/nmbd subj=system_u:system_r:nmbd_t:s0 key=(null) Hash: nmbd,nmbd_t,usermodehelper_t,file,open Version-Release number of selected component: selinux-policy-3.13.1-63.fc21.noarch Additional info: reporter: libreport-2.2.3 hashmarkername: setroubleshoot kernel: 3.16.0-0.rc4.git3.1.fc21.x86_64 type: libreport
