H A D | zcrypt_ep11misc.h | diff 386cb81e4ba7811573765aaaeb91b472639c2bae Fri Aug 11 09:56:20 CDT 2023 Holger Dengler <dengler@linux.ibm.com> s390/zcrypt_ep11misc: support API ordinal 6 with empty pin-blob
Secure execution guest environments require an empty pinblob in all key generation and unwrap requests. Empty pinblobs are only available in EP11 API ordinal 6 or higher.
Add an empty pinblob to key generation and unwrap requests, if the AP secure binding facility is available. In all other cases, stay with the empty pin tag (no pinblob) and the current API ordinals.
The EP11 API ordinal also needs to be considered when the pkey module tries to figure out the list of eligible cards for key operations with protected keys in secure execution environment.
These changes are transparent to userspace but required for running an secure execution guest with handling key generate and key derive (e.g. secure key to protected key) correct. Especially using EP11 secure keys with the kernel dm-crypt layer requires this patch.
