H A D | pkey.h | diff f370f45c6475ad0058277ae111f28fb32f58aa46 Sat Apr 01 14:32:08 CEST 2023 Harald Freudenberger <freude@linux.ibm.com> s390/pkey: do not use struct pkey_protkey
This is an internal rework of the pkey code to not use the struct pkey_protkey internal any more. This struct has a hard coded protected key buffer with MAXPROTKEYSIZE = 64 bytes. However, with support for ECC protected key, this limit is too short and thus this patch reworks all the internal code to use the triple u8 *protkey, u32 protkeylen, u32 protkeytype instead. So the ioctl which still has to deal with this struct coming from userspace and/or provided to userspace invoke all the internal functions now with the triple instead of passing a pointer to struct pkey_protkey.
Also the struct pkey_clrkey has been internally replaced in a similar way. This struct also has a hard coded clear key buffer of MAXCLRKEYSIZE = 32 bytes and thus is not usable with e.g. ECC clear key material.
This is a transparent rework for userspace applications using the pkey API. The internal kernel API used by the PAES crypto ciphers has been adapted to this change to make it possible to provide ECC protected keys via this interface in the future.
