2009-10-30bond: Simplify bond_create.Eric W. Biederman
Stop calling dev_get_by_name to see if the bond device already exists. register_netdevice already does that. Stop calling bond_deinit if register_netdevice fails as bond_uninit is guaranteed to be called if bond_init succeeds. Signed-off-by: Eric W.

2009-10-30bond: Simply bond sysfs group creationEric W. Biederman
This patch delegates the work of creating the sysfs groups to the netdev layer and ultimately to the device layer. This closes races between uevents. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-30net: Allow devices to specify a device specific sysfs group.Eric W. Biederman
This isn't beautifully abstracted, but it is simple, simplifies uses and so far is only needed for the bonding driver. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-30net: use hlist_for_each_entry()Eric Dumazet

2009-10-30veth: Fix veth_dellink methodEric Dumazet
In commit 23289a37e2b127dfc4de1313fba15bb4c9f0cd5b (net: add a list_head parameter to dellink() method), I forgot to actually use this parameter in veth_dellink. I remember feeling a bit uncomfortable about veth_close(), because it does : netif_carrier_off(dev); netif_carrier_off(priv->peer); Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-29vlan: cleanup multiple unregistrationsPatrick McHardy
The temporary copy of the VLAN group is not neccessary since the lower device is already in the process of being unregistered, if it was neccessary the memset of the global group would introduce a race condition. With this removed, the changes to the original code are only a few lines, so remove the new function and move the code back into vlan_device_event().

2009-10-29sfc: Feed GRO result into RX allocation policy and interrupt moderationBen Hutchings
When GRO is successfully merging received packets, we should allocate raw page buffers rather than skbs that will be discarded by GRO. Otherwise, we should allocate skbs. GRO also benefits from higher interrupt moderation, so increase the score for mergeable RX packets. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-29gro: Change all receive functions to return GRO result codesBen Hutchings

2009-10-29net: Fix 'Re: PACKET_TX_RING: packet size is too long'Gabor Gombas
Currently PACKET_TX_RING forces certain amount of every frame to remain unused. This probably originates from an early version of the PACKET_TX_RING patch that in fact used the extra space when the (since removed) CONFIG_PACKET_MMAP_ZERO_COPY option was enabled. The current code does not make any use of this extra space. This patch removes the extra space reservation and lets userspace make use of the full frame size.

2009-10-29net,socket: introduce DECLARE_SOCKADDR helper to catch overflow at build timeCyrill Gorcunov
proto_ops->getname implies copying protocol specific data into storage unit (particulary to __kernel_sockaddr_storage). So when we implement new protocol support we should keep such a detail in mind (which is easy to forget about). Lets introduce DECLARE_SOCKADDR helper which check if storage unit is not overfowed at build time. Eventually inet_getname is switched to use DECLARE_SOCKADDR (to show example of usage).

Some workloads hit dev_base_lock rwlock pretty hard. We can use RCU lookups to avoid touching this rwlock. netdevices are already freed after a RCU grace period, so this patch adds no penalty at device dismantle time. dev_ifname() converted to dev_get_by_index_rcu() Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-10-29gigaset: fix bad assumptions about CAPI skbuffsTilman Schmidt
The CAPI interface incorrectly assumed that CAPI messages would always start at the beginning of the data buffer: fix by treating DATA_B3 messages as the link layer header to their payload data. This fix changes the way acknowledgement information is propagated through the hardware specific modules and thereby impacts the ISDN4Linux variant of the driver, too. Also some assumptions about methods not being called from interrupt context turned out to be unwarranted; fix by using dev_kfree_skb_any() wherever non-interrupt context isn't guaranteed.

I found that the current version of drivers/net/usb/dm9601.c can be used to successfully drive a low-power, low-cost network adapter with USB ID 0a46:9000, based on a DM9000E chipset. As no device with this ID is yet present in the kernel, I have created a patch that adds support for the device to the dm9601 driver. Created and tested against linux-2.6.32-rc5.
