Description of problem: $ sudo sealert -l 95ccd54f-1262-4147-a662-b97e4c43c94d SELinux is preventing /usr/sbin/winbindd from write access on the sock_file unexpected. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that winbindd should be allowed write access on the unexpected sock_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 winbindd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:winbind_t:s0 Target Context system_u:object_r:nmbd_var_run_t:s0 Target Objects unexpected [ sock_file ] Source winbindd Source Path /usr/sbin/winbindd Port <Unknown> Host miracle.foo.com Source RPM Packages samba-winbind-3.6.6-88.fc16.x86_64 Target RPM Packages Policy RPM selinux-policy-3.10.0-89.fc16.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name miracle.foo.com Platform Linux miracle.foo.com 3.4.2-1.fc16.x86_64 #1 SMP Thu Jun 14 20:17:26 UTC 2012 x86_64 x86_64 Alert Count 185 First Seen Thu 19 Jul 2012 05:20:07 PM CDT Last Seen Fri 20 Jul 2012 08:31:15 AM CDT Local ID 95ccd54f-1262-4147-a662-b97e4c43c94d Raw Audit Messages type=AVC msg=audit(1342791075.761:2704): avc: denied { write } for pid=20442 comm="winbindd" name="unexpected" dev="tmpfs" ino=23991 scontext=system_u:system_r:winbind_t:s0 tcontext=system_u:object_r:nmbd_var_run_t:s0 tclass=sock_file type=SYSCALL msg=audit(1342791075.761:2704): arch=x86_64 syscall=connect success=no exit=EACCES a0=20 a1=7f8c3a32b7a8 a2=6e a3=2f64626d6e2f6e75 items=0 ppid=2080 pid=20442 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=winbindd exe=/usr/sbin/winbindd subj=system_u:system_r:winbind_t:s0 key=(null) Hash: winbindd,winbind_t,nmbd_var_run_t,sock_file,write audit2allow #============= winbind_t ============== allow winbind_t nmbd_var_run_t:sock_file write; audit2allow -R #============= winbind_t ============== allow winbind_t nmbd_var_run_t:sock_file write; Version-Release number of selected component (if applicable): selinux-policy-3.10.0-89.fc16.noarch samba-winbind-3.6.6-88.fc16.x86_64 How reproducible: I do not know the operation that winbind is attempting but it occurs every couple of minutes according to the syslog denial message time stamps. Actual results: Syslog denial message, but no known problem stems from this. Domain access seems to be functioning. Expected results: No syslog message.
