Subject: [PATCHv2-net-3.8 0/3] fix kernel crash with macvtap on top of LRO
Date: Thu, 7 Feb 2013 15:12:56 +0200 [thread overview]
Message-ID: <cover.1360236441.git.mst@redhat.com> (raw)
At the moment, macvtap crashes are observed if macvtap is attached
to an interface with LRO enabled.
The crash in question is BUG() in macvtap_skb_to_vnet_hdr.
This happens because several drivers set gso_size but not gso_type
in incoming skbs.
This didn't use to be the case: with intel cards on 3.2 and older
kernels, with qlogic - on 3.4 and older kernels, so it's a regression if
not a recent one.
The following patches fix this for qlogic, broadcom and intel drivers.
I tested that the patch fixes the crash for ixgbe but
don't have qlogic/broadcom hardware to test.
I also only tested TCPv4.
Please review, and consider for 3.8.
Changes from v1:
- added missing htons as suggested by Eric
- backported the relevant bits from
cbf1de72324a8105ddcc3d9ce9acbc613faea17e for bnx2x
