From: Roberto Sassu <roberto.sassu@xxxxxxxxxx>
Since the integrity (including IMA and EVM) functions are currently always
called by the LSM infrastructure, and always after all LSMs, formalize
these requirements by introducing a new LSM ordering called LSM_ORDER_LAST,
and set it for the 'integrity' LSM (patch 1).
Consequently, revert commit 92063f3ca73a ("integrity: double check
iint_cache was initialized"), as the double check becomes always verified
(patch 2), and remove 'integrity' from the list of LSMs in
security/Kconfig (patch 3).
Changelog:
v2:
- Fix commit message in patch 1 (suggested by Mimi)
- Bump version of patch 2 (v1 -> v3) to make one patch set
- Add patch 3 (suggested by Mimi)
v1:
- Add comment for LSM_ORDER_LAST definition (suggested by Mimi)
- Add Fixes tag (suggested by Mimi)
- Do minor corrections in the commit messages (suggested by Mimi and
Stefan)
