If anyone has any objections, please let me know. ------------------ From: Harald Freudenberger [ Upstream commit 80c20b2c6dc09296f2cfb438a7b919a55f31237e ] Introduce a new flag parameter for the both cprb send functions zcrypt_send_cprb() and zcrypt_send_ep11_cprb(). This new xflags parameter ("execution flags") shall be used to provide execution hints and flags for this crypto request. There are two flags implemented to be used with these functions: * ZCRYPT_XFLAG_USERSPACE - indicates to the lower layers that all the ptrs address userspace. So when construction the ap msg copy_from_user() is to be used. If this flag is NOT set, the ptrs address kernel memory and thus memcpy() is to be used. * ZCRYPT_XFLAG_NOMEMALLOC - indicates that this task must not allocate memory which may be allocated with io operations. For the AP bus and zcrypt message layer this means: * The ZCRYPT_XFLAG_USERSPACE is mapped to the already existing bool variable "userspace" which is propagated to the zcrypt proto implementations. * The ZCRYPT_XFLAG_NOMEMALLOC results in setting the AP flag AP_MSG_FLAG_MEMPOOL when the AP msg buffer is initialized.
