[0/1] selinux-testsuite: Add filesystem tests

Message

Richard Haines Dec. 20, 2019, 10:11 a.m. UTC

These tests should cover all the areas in selinux/hooks.c that touch
the 'filesystem' class. Each hooks.c function is listed in the 'test'
script as there are some permissions that are checked in multiple places.

Tested on Fedora 31 and Rawhide (5.5 for the new watch perm).

To test fanotify fs watch perm on 5.5+:
1) Build the testsuite policy first:
make -C policy load

2) Add the following CIL statements to watch.cil and install:
semodule -i watch.cil

(common filesystem (watch))
(classcommon filesystem filesystem)
(allow test_filesystem_t self(filesystem (watch)))
; Until 'fs_watch_all_fs(test_filesystem_t)' in Policy use:
(allow test_filesystem_t fs_t (filesystem (watch)))
; Required if notify policy enabled
;(allow test_filesystem_t self (dir (watch_sb)))

3) Edit /usr/share/selinux/devel/include/support/all_perms.spt
   and insert the 'watch' permission at:

define(`all_filesystem_perms',`{ mount remount ..... watch }')

Changes from RFC Patch:
1) Rename mount to filesystem as it is testing the fs permissions
2) Add tests for context=, rootcontext=, fscontext= and defcontext=
3) Add setfscreatecon(3) tests
4) Add tests to build fanotify on 5.5 and travis (not tested)
