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:

Because ndisc_send_na(), ndisc_send_ns() and ndisc_send_rs() are almost identical, so let's unify their common part.

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:

Do some simple changes to make congestion control API faster/cleaner. * use ktime_t rather than timeval * merge rtt sampling into existing ack callback this means one indirect call versus two per ack. * use flags bits to store options/settings Signed-off-by:

This patch creates the core cfg80211 code along with some sysfs bits. This is a stripped down version to allow mac80211 to function, but doesn't include any configuration yet except for creating and removing virtual interfaces. This patch includes the nl80211 header file but it only contains the interface types which the cfg80211 interface for creating virtual interfaces relies on. Signed-off-by:

This patch silences an IRDA_ASSERT in irda_recvmsg_stream, as described in http://bugzilla.kernel.org/show_bug.cgi?id=7512 irda_disconnect_indication would set sk->sk_err to ECONNRESET, and a subsequent call to recvmsg would print an irritating kernel message and return -1. When a connected socket is closed by the peer, recvmsg should return 0 rather than an error. This patch fixes this. Signed-off-by:
