* [NET] tun/tap: fixed hw address handlingBrian Braunstein2007-04-26
| | | | | | | | | | | | | | | | Fixed tun/tap driver's handling of hw addresses. The hw address is stored in both the net_device.dev_addr and tun.dev_addr fields. These fields were not kept synchronized, and in fact weren't even initialized to the same value. Now during both init and when performing SIOCSIFHWADDR on the tun device these values are both updated. However, if SIOCSIFHWADDR is performed on the net device directly (for instance, setting the hw address using ifconfig), the tun device does not get updated. Perhaps the tun.dev_addr field should be removed completely at some point, as it is redundant and net_device.dev_addr can be used anywhere it is used.

* [NET]: Clean up sk_buff walkers.Jean Delvare2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed recently that, in skb_checksum(), "offset" and "start" are essentially the same thing and have the same value throughout the function, despite being computed differently. Using a single variable allows some cleanups and makes the skb_checksum() function smaller, more readable, and presumably marginally faster. We appear to have many other "sk_buff walker" functions built on the exact same model, so the cleanup applies to them, too. Here is a list of the functions I found to be affected: net/appletalk/ddp.c:atalk_sum_skb() net/core/datagram.c:skb_copy_datagram_iovec() net/core/datagram.c:skb_copy_and_csum_datagram() net/core/skbuff.c:skb_copy_bits() net/core/skbuff.c:skb_store_bits() net/core/skbuff.c:skb_checksum() net/core/skbuff.c:skb_copy_and_csum_bit() net/core/user_dma.c:dma_skb_copy_datagram_iovec() net/xfrm/xfrm_algo.c:skb_icv_walk() net/xfrm/xfrm_algo.c:skb_to_sgvec() OTOH, I admit I'm a bit surprised, the cleanup is rather obvious so I'm really wondering if I am missing something. Can anyone please comment on this? Signed-off-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* [XFRM]: Export SAD info.Jamal Hadi Salim2007-04-26
| | | | | | | | | | | | | | | | On a system with a lot of SAs, counting SAD entries chews useful CPU time since you need to dump the whole SAD to user space; i.e something like ip xfrm state ls | grep -i src | wc -l I have seen taking literally minutes on a 40K SAs when the system is swapping. With this patch, some of the SAD info (that was already being tracked) is exposed to user space. i.e you do: ip xfrm state count And you get the count; you can also pass -s to the command line and get the hash info.

* [BRIDGE]: if no STP then forward all BPDUsStephen Hemminger2007-04-26
| | | | | | | | | | | | If a bridge is not running STP, then it has no way to detect a cycle in the network. But if it is not running STP and some other machine or device is running STP, then if STP BPDU's get forwarded to it can detect the cycle. This is how the old 2.4 and early 2.6 code worked.

* [BRIDGE]: don't change packet typeStephen Hemminger2007-04-26
| | | | | | | | | | The change to forward STP bpdu's (for usermode STP) through normal path, changed the packet type in the process. Since link local stuff is multicast, it should stay pkt_type = PACKET_MULTICAST. The code was probably copy/pasted incorrectly from the bridge pseudo-device receive path.

* [TIPC]: Enhancements to msg_set_bits() routineAllan Stephens2007-04-26
| | | | | | | | | | | | | | | | | | This patch makes two enhancements to msg_set_bits(): 1) It now ignores any bits of the new field value that are not covered by the mask being used. (Previously, if the new value exceeded the size of the mask the extra bits could corrupt other fields in the message header word being updated.) 2) The code has been optimized to minimize the number of run-time endianness conversion operations by leveraging the fact that the mask (and, in some cases, the value as well) is constant and the necessary conversion can be performed by the compiler.
