Description Steve Dickson 2017-06-12 13:47:49 UTC 
Description of problem:
When /run/rpcbind does not exist when rpcbind starts, it
will use the following command to create the directory:

/usr/bin/systemd-tmpfiles --create rpcbind.conf


SELinux is denying it:

audit[3813]: AVC avc:  denied  { execute } for  pid=3813 comm="sh" name="systemd-tmpfiles" dev="dm-1" ino=33591631 scontext=system_u:system_r:rpcbind_t:s0 tcontext=system_u:object_r:systemd_tmpfiles_exec_t:s0 tclass=file permissive=0

audit[3813]: AVC avc:  denied  { getattr } for  pid=3813 comm="sh" path="/usr/bin/systemd-tmpfiles" dev="dm-1" ino=33591631 scontext=system_u:system_r:rpcbind_t:s0 tcontext=system_u:object_r:systemd_tmpfiles_exec_t:s0 tclass=file permissive=0

audit[3813]: AVC avc:  denied  { getattr } for  pid=3813 comm="sh" path="/usr/bin/systemd-tmpfiles" dev="dm-1" ino=33591631 scontext=system_u:system_r:rpcbind_t:s0 tcontext=system_u:object_r:systemd_tmpfiles_exec_t:s0 tclass=file permissive=0


rpcbind[3812]: sh: /usr/bin/systemd-tmpfiles: Permission denied
rpcbind[3812]: rpcbind: /run/rpcbind/rpcbind.lock: No such file or directory
systemd[1]: rpcbind.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: Failed to start RPC Bind.

Comment 1 Francesco Simula 2017-06-12 17:01:59 UTC 
Created attachment 1287077 [details]
output of "sudo grep -i avc /var/log/audit/audit.log | ausearch -i"

I've attached the output of "sudo grep -i avc /var/log/audit/audit.log | ausearch -i", I hope it is enough to diagnose the problem.

I must add that other (identical, maybe a little fresher) installations here have accepted the update without problems, while other ones (like the one the output comes from) have not, so it must be something specific to the installation but I cannot fathom what...
Comment 2 Daniel Walsh 2017-06-12 20:15:09 UTC 
Looks like we should just add
systemd_tmpfiles_exec(rpcbind_t)
