All function declarations are "extern" by default, there is no need to specify it explicitly. For C99 states in 6.2.2.5: "If the declaration of an identifier for a function has no storage-class specifier, its linkage is determined exactly as if it were declared with the storage-class specifier extern."

The security offload function is performed by a cryptographic engine core attached to the 128-bit PLB (processor local bus) with builtin DMA and interrupt controllers. This, I think, satisfies the requirement for the CRYPTO_ALG_KERN_DRIVER_ONLY flag. Signed-off-by:

Arrays aesni_simd_skciphers and aesni_simd_skciphers2 are local to the source and do not need to be in global scope, so make them static.

When two adjacent TX SGL are processed and parts of both TX SGLs are pulled into the per-request TX SGL, the wrong per-request TX SGL entries were updated. This fixes a NULL pointer dereference when a cipher implementation walks the TX SGL where some of the SGL entries were NULL. Fixes: e870456d ("crypto: algif_skcipher - overhaul memory...")

Using RBP as a temporary register breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code. Use R13 instead of RBP. Both are callee-saved registers, so the substitution is straightforward. Reported-by:

Using RBP as a temporary register breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code. Mix things up a little bit to get rid of the RBP usage, without hurting performance too much. Use RDI instead of RBP for the TBL pointer. That will clobber CTX, so spill CTX onto the stack and use R12 to read it in the outer loop. R12 is used as a non-persistent temporary variable elsewhere, so it's safe to use. Also remove the unused y4 variable. Reported-by:

Using RBP as a temporary register breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code. Swap the usages of R12 and RBP. Use R12 for the TBL register, and use RBP to store the pre-aligned stack pointer. Reported-by:

Using RBP as a temporary register breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code. There's no need to use RBP as a temporary register for the TBL value, because it always stores the same value: the address of the K256 table. Instead just reference the address of K256 directly.

Using RBP as a temporary register breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code. Use R11 instead of RBP. Since R11 isn't a callee-saved register, it doesn't need to be saved and restored on the stack. Reported-by:
