Subject: [PATCH v1 0/1] s390/crypto: Generate iintermediate chaining value on export
Date: Fri, 14 Aug 2026 16:20:09 +0200 [thread overview]
Message-ID: <20260814142010.259918-1-dengler@linux.ibm.com> (raw)
While exporting the state of the hmac chipher, the intermediate
chaining value (CV) has to be calculated. Calling the KIMD instruction
on s390 will generate the correct value. The code already sets the
correct function code for the instruction, but it calls the wrong
instruction (KLMD). The patch just fixes this.
This series applies on top of Linus' master branch.
