Dear Maintainer,

chcon doesn't setfilecon() when the current context is already the one
requested, mirroring chgrp.

Observe, however chgrp -v:
  $ chgrp -v users fips180-2withchangenotice.pdf fips180-3_final.pdf
  group of 'fips180-2withchangenotice.pdf' retained as users
  changed group of 'fips180-3_final.pdf' from nabijaczleweli to users
as contrasted with chcon -v:
  # ls -Z /mnt/*_t | cat
        unconfined_u:object_r:tmp_t:s0 /mnt/tmp_t
  unconfined_u:object_r:unlabeled_t:s0 /mnt/unlabeled_t
  # chcon -v -t tmp_t /mnt/*_t
  changing security context of '/mnt/tmp_t'
  changing security context of '/mnt/unlabeled_t'

A re-run confirms this is a lie:
  # strace chcon -v -t tmp_t /mnt/*_t  2>&1 | grep xattr
  getxattr("/mnt/tmp_t", "security.selinux", "unconfined_u:object_r:tmp_t:s0", 
255) = 31
  getxattr("/mnt/unlabeled_t", "security.selinux", 
"unconfined_u:object_r:unlabeled_"..., 255) = 37
  setxattr("/mnt/unlabeled_t", "security.selinux", 
"unconfined_u:object_r:tmp_t:s0", 31, 0) = 0

Best,
наб
