Thanks guys, here an updated version then, before linkwatch surgery ? In this version, I force the event to be sent synchronously. [PATCH net-next-2.6] linkwatch: linkwatch_forget_dev() to speedup device dismantle time ip link del eth3.103 ; time ip link del eth3.104 ; time ip link del eth3.105 real 0m0.266s user 0m0.000s sys 0m0.001s real 0m0.770s user 0m0.000s sys 0m0.000s real 0m1.022s user 0m0.000s sys 0m0.000s One problem of current schem in vlan dismantle phase is the holding of device done by following chain : vlan_dev_stop() -> netif_carrier_off(dev) -> linkwatch_fire_event(dev) -> dev_hold() ... And __linkwatch_run_queue() runs up to one second later... A generic fix to this problem is to add a linkwatch_forget_dev() method to unlink the device from the list of watched devices. dev->link_watch_next becomes dev->link_watch_list (and use a bit more memory), to be able to unlink device in O(1). After patch : time ip link del eth3.103 ; time ip link del eth3.104 ; time ip link del eth3.105 real 0m0.024s user 0m0.000s sys 0m0.000s real 0m0.032s user 0m0.000s sys 0m0.001s real 0m0.033s user 0m0.000s sys 0m0.000s Signed-off-by:

This new event is called once for each unique net namespace in batched unregister operations (with the argument set to a random device from that namespace) and once per device in non-batched unregister operations. It allows us to factorize some device unregister work such as clearing the routing cache. Signed-off-by:

With multi queue devices, its possible that several cpus call macvlan RX routines simultaneously for the same macvlan device. We update RX stats counter without any locking, so we can get slightly wrong counters. One possible fix is to use percpu counters, to get precise accounting and also get guarantee of no cache line ping pongs between cpus. Note: this adds 16 bytes (32 bytes on 64bit arches) of percpu data per macvlan device. Signed-off-by:

This patch removes config dependency on x86 to build vmxnet3 driver. Thus the driver can be built on big endian architectures now. Although vmxnet3 is not supported on VMs other than x86 architecture, all this code goes in to ensure correctness. If the code is not dependent on x86, it should not assume little endian architecture in any of its operations. Signed-off-by:

The netlink URELEASE notifier doesn't notify for sockets that have been used to receive multicast but it should be called for such sockets as well since they might _also_ be used for sending and not solely for receiving multicast. We will need that for nl80211 (generic netlink sockets) in the future. Signed-off-by:

ks8695_rx() will call refill_buffers() for every incoming packet. Its not necessary. We just need do it after finishing receiving thing. And the 'RX dma engine' is in the same situation. This blocks our user space application. The following patch may fix it. Signed-off-by:

ks8695 rx irq is edge-level. Before arriving at irq handler, the corresponding status bit has been clear(irq's ack). So we should not check it after that. Signed-off-by:

PPP does not correctly call pskb_may_pull() on all necessary receive paths before reading the PPP protocol, thus causing PPP to report seemingly random 'unsupported protocols' and eventually trigger BUG_ON(skb->len < skb->data_len) in skb_pull_rcsum() when receiving multilink protocol in non-linear skbs. ppp_receive_nonmp_frame() does not call pskb_may_pull() before reading the protocol number. For the non-mp receive path this is not a problem, as this check is done in ppp_receive_frame(). For the mp receive path, ppp_mp_reconstruct() usually copies the data into a new linear skb. However, in the case where the frame is made up of a single mp fragment, the mp header is pulled and the existing skb used. This skb was then passed to ppp_receive_nonmp_frame() without checking if the encapsulated protocol header could safely be read. Signed-off-by:

net: Fix the rollback test in dev_change_name() In dev_change_name() an err variable is used for storing the original call_netdevice_notifiers() errno (negative) and testing for a rollback error later, but the test for non-zero is wrong, because the err might have positive value as well - from dev_alloc_name(). It means the rollback for a netdevice with a number > 0 will never happen. (The err test is reordered btw. to make it more readable.) Signed-off-by:
