In the print out add permissions, it will look like:
     <...>-1042  [007] ....   201.965142: selinux_audited:
     requested=0x4000000 denied=0x4000000 audited=0x4000000
     result=-13
     scontext=system_u:system_r:cupsd_t:s0-s0:c0.c1023
     tcontext=system_u:object_r:bin_t:s0
     tclass=file permissions={ !entrypoint }

This patch is adding the "permissions={ !entrypoint }".
The permissions preceded by "!" have been denied and the permissions
without have been accepted.

Note that permission filtering is done on the audited, denied or
requested attributes.

Does this require a corresponding patch to userspace?  Otherwise, I get the following:

libtraceevent: No such file or directory
  [avc:selinux_audited] function avc_trace_perm_to_name not defined
