davinci_emac.c: Fix IFF_ALLMULTI setup

2013-11-04T12:31:05Z

[ Upstream commit d69e0f7ea95fef8059251325a79c004bac01f018 ] When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't, emac_dev_mcast_set should only enable RX of multicasts and reset MACHASH registers. It does this, but afterwards it either sets up multicast MACs filtering or disables RX of multicasts and resets MACHASH registers again, rendering IFF_ALLMULTI flag useless. This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set. Tested with kernel 2.6.37.

be2net: pass if_id for v1 and V2 versions of TX_CREATE cmd

2013-11-04T12:31:04Z

[ Upstream commit 0fb88d61bc60779dde88b0fc268da17eb81d0412 ] It is a required field for all TX_CREATE cmd versions > 0. This fixes a driver initialization failure, caused by recent SH-R Firmwares (versions > 10.0.639.0) failing the TX_CREATE cmd when if_id field is not passed.

wanxl: fix info leak in ioctl

virtio-net: refill only when device is up during setting queues

2013-11-04T12:31:03Z

[ Upstream commit 35ed159bfd96a7547ec277ed8b550c7cbd9841b6 ] We used to schedule the refill work unconditionally after changing the number of queues. This may lead an issue if the device is not up. Since we only try to cancel the work in ndo_stop(), this may cause the refill work still work after removing the device. Fix this by only schedule the work when device is up.

virtio-net: fix the race between channels setting and refill

[ Upstream commit 9b9cd8024a2882e896c65222aa421d461354e3f2 ] Commit 55257d72bd1c51f25106350f4983ec19f62ed1fa (virtio-net: fill only rx queues which are being used) tries to refill on demand when changing the number of channels by call try_refill_recv() directly, this may race: - the refill work who may do the refill in the same time - the try_refill_recv() called in bh since napi was not disabled Which may led guest complain during setting channels: virtio_net virtio0: input.1:id 0 is not a head!

virtio-net: don't respond to cpu hotplug notifier if we're not ready

2013-11-04T12:31:03Z

[ Upstream commit 3ab098df35f8b98b6553edc2e40234af512ba877 ] We're trying to re-configure the affinity unconditionally in cpu hotplug callback. This may lead the issue during resuming from s3/s4 since - virt queues haven't been allocated at that time. - it's unnecessary since thaw method will re-configure the affinity. Fix this issue by checking the config_enable and do nothing is we're not ready.

bnx2x: record rx queue for LRO packets

2013-11-04T12:31:03Z

[ Upstream commit 60e66fee56b2256dcb1dc2ea1b2ddcb6e273857d ] RPS support is kind of broken on bnx2x, because only non LRO packets get proper rx queue information. This triggers reorders, as it seems bnx2x like to generate a non LRO packet for segment including TCP PUSH flag : (this might be pure coincidence, but all the reorders I've seen involve segments with a PUSH) 11:13:34.335847 IP A > B: . 415808:447136(31328) ack 1 win 457 11:13:34.335992 IP A > B: . 447136:448560(1424) ack 1 win 457 11:13:34.336391 IP A > B: . 448560:479888(31328) ack 1 win 457 11:13:34.336425 IP A > B: P 511216:512640(1424) ack 1 win 457 11:13:34.336423 IP A > B: . 479888:511216(31328) ack 1 win 457 11:13:34.336924 IP A > B: . 512640:543968(31328) ack 1 win 457 11:13:34.336963 IP A > B: . 543968:575296(31328) ack 1 win 457 We must call skb_record_rx_queue() to properly give to RPS (and more generally for TX queue selection on forward path) the receive queue information. Similar fix is needed for skb_mark_napi_id(), but will be handled in a separate patch to ease stable backports.

xen-netback: Don't destroy the netdev until the vif is shut down

2013-11-04T12:31:01Z

[ upstream commit id: 279f438e36c0a70b23b86d2090aeec50155034a9 ] Without this patch, if a frontend cycles through states Closing and Closed (which Windows frontends need to do) then the netdev will be destroyed and requires re-invocation of hotplug scripts to restore state before the frontend can move to Connected. Thus when udev is not in use the backend gets stuck in InitWait. With this patch, the netdev is left alone whilst the backend is still online and is only de-registered and freed just prior to destroying the vif (which is also nicely symmetrical with the netdev allocation and registration being done during probe) so no re-invocation of hotplug scripts is required.
