Hi Steffen:
I received a bug report regarding poor IPComp performance over
IPv6:
https://bugzilla.redhat.com/show_bug.cgi?id=1257952
It appears to have been caused by
commit dd767856a36e00b631d65ebc4bb81b19915532d6
Author: Steffen Klassert <steffen.klass...@secunet.com>
Date: Tue Oct 11 01:44:30 2011 +0000
xfrm6: Don't call icmpv6_send on local error
which addded an MTU check without a GSO override.
Fixing it obviously isn't difficult, but I am wondering why I
can't find a corresponding patch for IPv4. Do we need that check
to be present in xfrm6_output at all? If we do why isn't it needed
for IPv4 as well?
Thanks,
--
