commit 3edc22655647378dea01900f7b04e017ff96bda9 upstream.

No other platform needs CA_MACHINE_KEYRING, either.

This is policy that should be decided by the administrator, not Kconfig

Merge tag 'tpmdd-v6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd

Pull tpm updates from Jarkko Sakkinen:

- The .machine keyring, used for Machine Owner Keys (MOK), acquired the
ability to store only CA enforced keys, and put rest to the .platform
keyring, thus separating the code signing keys from the keys that are
used to sign certificates.

This essentially unlocks the use of the .machine keyring as a trust
anchor for IMA. It is an opt-in feature, meaning that the additional
contraints won't brick anyone who does not care about them.

- Enable interrupt based transactions with discrete TPM chips (tpm_tis).

There was code for this existing but it never really worked so I
consider this a new feature rather than a bug fix. Before the driver
just fell back to the polling mode.

integrity: machine keyring CA configuration

Add machine keyring CA restriction options to control the type of
keys that may be added to it. The motivation is separation of
certificate signing from code signing keys. Subsquent work will
limit certificates being loaded into the IMA keyring to code
signing keys used for signature verification.

When no restrictions are selected, all Machine Owner Keys (MOK) are added
to the machine keyring. When CONFIG_INTEGRITY_CA_MACHINE_KEYRING is
selected, the CA bit must be true. Also the key usage must contain
keyCertSign, any other usage field may be set as well.

When CONFIG_INTEGRITY_CA_MACHINE_KEYRING_MAX is selected, the CA bit must
be true. Also the key usage must contain keyCertSign and the
digitialSignature usage may not be set.
