Subjectunix_getname buglet - > 2.5.4(?)
From
Date
Hi there,

Evolution is non-functioning on recent 2.5.X kernels, due to
mal-performance in getpeername => net/unix/af_unix.c (unix_getname),
where it seems we switch 'sk' on 'peer', but not the (previously)
typecast pointer to it; this fixes it.

Thanks Joaquim Fellmann (AFAIR) who chased this down to bitkeeper
changeset 1.262.2.2. Sadly I didn't have time to read the rest of that
changeset to see if the mistake pops up elsewhere as well. Please CC me
with replies, not on linux-kernel.

HTH,

Michael Meeks.
