Subject: [PATCH v1 0/2] cleanup stackprotector canary generation
Date: Sun, 23 Oct 2022 22:32:06 +0200 [thread overview]
Message-ID: <20221023203208.118919-1-Jason@zx2c4.com> (raw)
Stack canary generation currently lives partially in random.h, where it
doesn't belong, and is in general a bit overcomplicated. This small
patchset fixes up both issues. I'll take these in my tree, unless
somebody else prefers to do so.
