Export the keyring key type definition and document its availability. Add alternative types into the key's type_data union to make it more useful. Not all users necessarily want to use it as a list_head (AF_RXRPC doesn't, for example), so make it clear that it can be used in other ways. Signed-off-by:

del_timer_sync() buys nothing for cancel_delayed_work(), but it is less efficient since it locks the timer unconditionally, and may wait for the completion of the delayed_work_timer_fn(). cancel_delayed_work() == 0 means: before this patch: work->func may still be running or queued after this patch: work->func may still be running or queued, or delayed_work_timer_fn->__queue_work() in progress. The latter doesn't differ from the caller's POV, delayed_work_timer_fn() is called with _PENDING bit set. cancel_delayed_work() == 1 with this patch adds a new possibility: delayed_work->work was cancelled, but delayed_work_timer_fn is still running (this is only possible for the re-arming works on single-threaded workqueue). In this case the timer was re-started by work->func(), nobody else can do this. This in turn means that delayed_work_timer_fn has already passed __queue_work() (and wont't touch delayed_work) because nobody else can queue delayed_work->work. Signed-off-by:

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. Signed-off-by:

drivers/net/hamradio/yam.c: In function `yam_tx_byte': drivers/net/hamradio/yam.c:643: warning: passing arg 1 of `skb_copy_from_linear_data_offset' from incompatible pointer type Signed-off-by:

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:

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.

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. Signed-off-by:

Pause frames should never make it out of the network device into the stack. But if a device was misconfigured, it might happen. So drop pause frames in bridge. Signed-off-by:

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. Signed-off-by:

This patch moves the non-proc SNMP code into addrconf.c and reuses IPv4 SNMP code where applicable. As a result we can skip proc.o if /proc is disabled. Note that I've made a number of functions static since they're only used by addrconf.c for now. If they ever get used elsewhere we can always remove the static. Signed-off-by:

This patch moves the SNMP code shared between IPv4/IPv6 from proc.c into net/ipv4/af_inet.c. This makes sense because these functions aren't specific to /proc. As a result we can again skip proc.o if /proc is disabled. Signed-off-by:

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.

Now that Patrick has added the code to deal with GSO in netfilter, we no longer need the crutch that computes partial checksums just before transmission. This patch turns this into a warning again. If this goes OK, we can then turn it into a BUG_ON and remove the gso_send_check cruft. Signed-off-by:
