2006-03-19[AX.25]: Fix potencial memory hole.Ralf Baechle DL5RB
If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3 (or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall through the switch statement without calling ax25_send_iframe() or any other function that would eventually free skbn thus leaking the packet. Fix by restricting the sysctl inferface to allow only actually supported AX.25 dialects. The system administration mistake needed for this to happen is rather unlikely, so this is an uncritical hole.

2006-03-17[PATCH] ieee80211: Don't update network statistics from off-channel packets.James Ketrenos
This patch fixes a problem in the ieee80211 probe response and beacon reception code that would use the packet statistics for a network even if they were received on a channel other than that which the network exists on. This causes a problem in overlapping channels where, for example, a strong AP on channel 2 could have its beacons received on channels 1 and 3, but at much lower signal levels. If scanning was done sequentially, this means the beacon received on channel 3 would update the AP's signal level as being much lower than it really is, which subsequently could cause that AP to be passed over and an alternate AP selected.

2006-03-15[PATCH] ieee80211: Fix QoS is not active problemHong Liu
Fix QoS is not active even the network and the card is QOS enabled. The problem is we pass the wrong ieee80211_network address to ipw_handle_beacon/ipw_handle_probe_response, thus the ieee80211_network->qos_data.active will not be set, causing the driver not sending QoS frames at all.

2006-03-08[PATCH] fix file countingDipankar Sarma
I have benchmarked this on an x86_64 NUMA system and see no significant performance difference on kernbench. Tested on both x86_64 and powerpc. The way we do file struct accounting is not very suitable for batched freeing. For scalability reasons, file accounting was constructor/destructor based. This meant that nr_files was decremented only when the object was removed from the slab cache. This is susceptible to slab fragmentation. With RCU based file structure, consequent batched freeing and a test program like Serge's, we just speed this up and end up with a very fragmented slab - llm22:~ # cat /proc/sys/fs/file-nr 587730 0 758844 At the same time, I see only a 2000+ objects in filp cache. The following patch I fixes this problem. This patch changes the file counting by removing the filp_count_lock. Instead we use a separate percpu counter, nr_files, for now and all accesses to it are through get_nr_files() api. In the sysctl handler for nr_files, we populate files_stat.nr_files before returning to user. Counting files as an when they are created and destroyed (as opposed to inside slab) allows us to correctly count open files with RCU. Signed-off-by: Dipankar Sarma <dipankar@in.ibm.com> Cc: "Paul E.

2006-03-07[NETFILTER] ip_queue: Fix wrong skb->len == nlmsg_len assumptionThomas Graf
The size of the skb carrying the netlink message is not equivalent to the length of the actual netlink message due to padding. ip_queue matches the length of the payload against the original packet size to determine if packet mangling is desired, due to the above wrong assumption arbitary packets may not be mangled depening on their original size.

2006-03-03[PATCH] bonding: suppress duplicate packetsJay Vosburgh
Originally submitted by Kenzo Iwami; his original description is: The current bonding driver receives duplicate packets when broadcast/ multicast packets are sent by other devices or packets are flooded by the switch. In this patch, new flags are added in priv_flags of net_device structure to let the bonding driver discard duplicate packets in dev.c:skb_bond(). Modified by Jay Vosburgh to change a define name, update some comments, rearrange the new skb_bond() for clarity, clear all bonding priv_flags on slave release, and update the driver version.

2006-02-27[PATCH] ieee80211_geo.c: remove frivolous BUG_ON'sPete Zaitcev
I have come to consider BUG_ON generally harmful. The idea of an assert is to prevent a program to execute past a point where its state is known erroneous, thus preventing it from dealing more damage to the data (or hiding the traces of malfunction). The problem is, in kernel this harm has to be balanced against the harm of forced reboot. The last straw was our softmac tree, where "iwlist eth1 scan" causes a lockup. It is absolutely frivolus and provides no advantages a normal assert has to provide. In fact, doing this impedes debugging. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: John W.

2006-02-27[IPSEC]: Kill post_input hook and do NAT-T in esp_input directlyHerbert Xu
The only reason post_input exists at all is that it gives us the potential to adjust the checksums incrementally in future which we ought to do. However, after thinking about it for a bit we can adjust the checksums without using this post_input stuff at all. The crucial point is that only the inner-most NAT-T SA needs to be considered when adjusting checksums. What's more, the checksum adjustment comes down to a single u32 due to the linearity of IP checksums. We just happen to have a spare u32 lying around in our skb structure :) When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum is currently unused. All we have to do is to make that the checksum adjustment and voila, there goes all the post_input and decap structures! I've left in the decap data structures for now since it's intricately woven into the sec_path stuff. We can kill them later too.
