[PATCH 0/4] Code improvements in integrity and IMA

[Thiago Jung Bauermann]

Hello,

These patches come from the "appended signatures support for IMA appraisal"
series. They are code improvements and cleanups and I decided to submit
them separately for a couple of reasons:

1. they stand on their own and could be included in v4.17;

2. this will simplify the original patch series a bit, by having it contain
   only the patches actually necessary to implement the feature.

These are the changes made to them since v5 of the modsig series:

- Patch "integrity: Remove unused macro IMA_ACTION_RULE_FLAGS"
  - New patch.

- Patch "ima: Improvements in ima_appraise_measurement()"
  - Moved is_ima_sig() to its own patch (not in this series).

Mimi Zohar (1):
  ima: Improvements in ima_appraise_measurement()

Thiago Jung Bauermann (3):
  integrity: Remove unused macro IMA_ACTION_RULE_FLAGS
  ima: Simplify ima_eventsig_init()
  integrity: Introduce struct evm_xattr
