Subject: PATCH: mips64 bogus setsockopt translation
Date: Sat, 19 Jul 2003 18:33:10 -0700 [thread overview]
Message-ID: <20030720013310.GB3093@foobazco.org> (raw)
DaveM recently nuked this translation that breaks icmpv6 filters from
sparc64. We have a copy of it, and ours is surely just as wrong.
Here's a patch.
