Hi Linus,

The large majority of the changes are EVM portable & immutable
signature related: removing a dependency on loading an HMAC key, safely
allowing file metadata included in the EVM portable & immutable
signatures to be modified, allowing EVM signatures to fulfill IMA file
signature policy requirements, including the EVM file metadata
signature in lieu of an IMA file data signature in the measurement
list, and adding dynamic debugging of EVM file metadata.

In addition, in order to detect critical data or file change
reversions, duplicate measurement records are permitted in the IMA
measurement list.  The remaining patches address compiler, sparse, and
doc warnings.



The following changes since commit d07f6ca923ea0927a1024dfccafc5b53b61cfecc:

  Linux 5.13-rc2 (2021-05-16 15:27:44 -0700)
