This reverts commit 73ce7b01. After discovering that we don't listen to gratuitious arps in 2.6.30 I tracked the failure down to this commit. The patch makes absolutely no sense. RFC2131 RFC3927 and RFC5227. are all in agreement that an arp request with sip == 0 should be used for the probe (to prevent learning) and an arp request with sip == tip should be used for the gratitous announcement that people can learn from. It appears the author of the broken patch got those two cases confused and modified the code to drop all gratuitous arp traffic. Ouch! Cc: stable@kernel.org Signed-off-by:

This patch addresses three WARN_ON statements from DMA-API debug code ixgbe is mapping more than it unmaps, reduce the length of the map call and remove the "used once" local variable. found by Joerg Roedel <joerg.roedel@amd.com> in 2.6.30, so is a candidate for -stable. in addition, fix missing ->dma = 0 after unmap to prevent double free with pci_unmap_single and lastly, don't unmap (half) pages that aren't mapped.

If a socket starts out on a non-TSO route, and then switches to a TSO route, then we will tack on data to the tail of the tx queue even if it started out life as non-TSO. This is suboptimal because all of it will then be copied and checksummed unnecessarily. This patch fixes this by ensuring that skb->ip_summed is set to CHECKSUM_PARTIAL before appending extra data beyond the MSS. Signed-off-by:

If a socket starts out on a non-TSO route, and then switches to a TSO route, then the tail on the tx queue can morph into a TSO packet, causing mischief because the rest of the stack does not expect a partially linear TSO packet. This patch fixes this by ensuring that skb->ip_summed is set to CHECKSUM_PARTIAL before declaring a packet as TSO. Reported-by:

When NAT helpers change the TCP packet size, the highest seen sequence number needs to be corrected. This is currently only done upwards, when the packet size is reduced the sequence number is unchanged. This causes TCP conntrack to falsely detect unacknowledged data and decrease the timeout. Fix by updating the highest seen sequence number in both directions after packet mangling. Tested-by:

While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames. With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[]. Now we coalesce the frags from the same physical page into one slot in skb_shinfo(skb)->frags[] and go to the next index when the frag is from different physical page. This patch is against the net-2.6 tree. Signed-off-by:

When NAPI is disabled while we're in net_rx_action, we end up calling __napi_complete without flushing GRO packets. This is a bug as it would cause the GRO packets to linger, of course it also literally BUGs to catch error like this :) This patch changes it to napi_complete, with the obligatory IRQ reenabling. This should be safe because we've only just disabled IRQs and it does not materially affect the test conditions in between. Signed-off-by:

As transparent proxying looks up the socket early and assigns it to the skb for later processing, we must drop any existing socket ownership prior to that in order to distinguish between the case where tproxy is active and where it is not. Signed-off-by:

The mac80211 module uses rcu_call() thus it should use rcu_barrier() on module unload. The rcu_barrier() is placed in mech.c ieee80211_stop_mesh() which is invoked from ieee80211_stop() in case vif.type == NL80211_IFTYPE_MESH_POINT. Acked-by:

As a hint for checking, the functions calling call_rcu() (unx_destroy_cred and generic_destroy_cred) are registered as crdestroy function pointer in struct rpc_credops. Acked-by:
