Subject: [PATCH 00/12] x86/crypto: Fix RBP usage in several crypto .S files
Date: Tue, 29 Aug 2017 13:05:33 -0500 [thread overview]
Message-ID: <cover.1504029132.git.jpoimboe@redhat.com> (raw)
Many of the x86 crypto functions use RBP as a temporary register. This
breaks frame pointer convention, and breaks stack traces when unwinding
from an interrupt in the crypto code.
Convert most* of them to leave RBP alone.
These pass the crypto boot tests for me. Any further testing would be
appreciated!
[*] There are still a few crypto files left that need fixing, but the
fixes weren't trivial and nobody reported unwinder warnings about
them yet, so I'm skipping them for now.
