Subject: [PATCH wireless-next 6/6] crypto: Remove michael_mic from crypto_shash API
Date: Sat,  4 Apr 2026 22:27:34 -0700	[thread overview]
Message-ID: <20260405052734.130368-7-ebiggers@kernel.org> (raw)
In-Reply-To: <20260405052734.130368-1-ebiggers@kernel.org>

Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used.  Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.

It makes sense that no other users ever appeared: Michael MIC is an
insecure algorithm that is specific to WPA TKIP, which itself was an
interim security solution to replace the broken WEP standard.
