Description kyoneyama 2018-07-09 01:49:21 UTC
Description of problem:

When there is "/etc/selinux/fixfiles_exclude_dirs", it doesn't label the rule added by "semanage fcontext" during autorelabel on boot.

Autorelabel on boot runs "fixfiles restore".

If there is fixfiles_exclude_dirs, fixfiles performs the operations below, that creates a temporary `file_contexts` files and executes setfiles based on a temporary files.

  # cd /etc/selinux/targeted/contexts/files/
  # mktemp file_contexts.XXXXXXXXX
  # cp -p /etc/selinux/targeted/contexts/files/file_contexts file_contexts.WniqAxMKPP
  # cp -p /etc/selinux/targeted/contexts/files/file_contexts.subs_dist file_contexts.WniqAxMKPP.subs_dist
  # cp -p /etc/selinux/targeted/contexts/files/file_contexts.subs file_contexts.WniqAxMKPP.subs
  # cp -p /etc/selinux/targeted/contexts/files/file_contexts.homedirs file_contexts.WniqAxMKPP.homedirs
  # setfiles -v -e /boot/efi -q /etc/selinux/targeted/contexts/files/file_contexts.WniqAxMKPP /


However, a temporary file of /etc/selinux/targeted/contexts/files/file_contexts.local isn't created, which additional rules are logged.
That's why fixfiles can't label additional rules.


Version-Release number of selected component (if applicable):

  - Red Hat Enterprise Linux 7.5
  - policycoreutils-2.5-22.el7

How reproducible:

  - Always

Steps to Reproduce:

1. Add local labeling rule with "semanage fcontext"

  # mkdir /share
  # semanage fcontext -a -t samba_share_t /share

2. Create /etc/selinux/fixfiles_exclude_dirs

  # echo "/boot/efi" > /etc/selinux/fixfiles_exclude_dirs

3. Execute "fixfiles restore"

  # fixfiles -v restore

4. Ensure the file context of /share

  # ls -ldZ /share

Actual results:

  - It doesn't label additional labels.

Expected results:

  - It can label additional labels.
