net/macb: fix race with RX interrupt while doing NAPI

2013-02-13T18:34:10Z

When interrupts are disabled, an RX condition can occur but it is not reported when enabling interrupts again. We need to check RSR and use napi_reschedule() if condition is met. Signed-off-by: Nicolas Ferre Signed-off-by: David S. Miller

atl1c: add error checking for pci_map_single functions

2013-02-13T18:32:37Z

it is reported that code hit DMA-API errors on 3.8-rc6+, (see https://bugzilla.redhat.com/show_bug.cgi?id=908436, and https://bugzilla.redhat.com/show_bug.cgi?id=908550) this patch just adds error handler for pci_map_single and skb_frag_dma_map. Signed-off-by: xiong Signed-off-by: David S. Miller

John W. Linville says: ==================== Here is another handful of late-breaking fixes intended for the 3.8 stream... Hopefully the will still make it! :-) There are three mac80211 fixes pulled from Johannes: "Here are three fixes still for the 3.8 stream, the fix from Cong Ding for the bad sizeof (Stephen Hemminger had pointed it out before but I'd promptly forgotten), a mac80211 managed-mode channel context usage fix where a downgrade would never stop until reaching non-HT and a bug in the channel determination that could cause invalid channels like HT40+ on channel 11 to be used." Also included is a mwl8k fix that avoids an oops when using mwl8k devices that only support the 5 GHz band. Please let me know if there are problems! ==================== Signed-off-by: David S.

ixgbe: Only set gso_type to SKB_GSO_TCPV4 as RSC does not support IPv6

2013-02-12T21:07:19Z

The original fix that was applied for setting gso_type required more change than necessary because it was assumed ixgbe does RSC on IPv6 frames and this is not correct. RSC is only supported with IPv4/TCP frames only. As such we can simplify the fix and avoid the unnecessary move of eth_type_trans. The previous patch "ixgbe: fix gso type" and this patch reduce the entire fix to one line that sets gso_type to TCPV4 if the frame is RSC. Signed-off-by: Alexander Duyck Signed-off-by: David S.

mwl8k: fix band for supported channels

2013-02-11T19:31:36Z

The band field for the supported channels were left unpopulated, making them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels. This resulted in null pointer accesses if anything tries to access wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).

bnx2x: set gso_type

2013-02-11T01:14:13Z

In LRO mode, bnx2x set gso_size but not gso type. This leads to crashes in macvtap. Commit cbf1de72324a8105ddcc3d9ce9acbc613faea17e queued for 3.9 includes a more complete fix. This is a minimal patch to avoid the crash, for 3.8. Signed-off-by: Michael S. Tsirkin Acked-by: Dmitry Kravkov Signed-off-by: David S. Miller
