2008-01-09[ATM]: Check IP header validity in mpc_send_packetHerbert Xu
Al went through the ip_fast_csum callers and found this piece of code that did not validate the IP header. While root crashing the machine by sending bogus packets through raw or AF_PACKET sockets isn't that serious, it is still nice to react gracefully. This patch ensures that the skb has enough data for an IP header and that the header length field is valid. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2008-01-09[XFRM]: xfrm_algo_clone() allocates too much memoryEric Dumazet
alg_key_len is the length in bits of the key, not in bytes. Best way to fix this is to move alg_len() function from net/xfrm/xfrm_user.c to include/net/xfrm.h, and to use it in xfrm_algo_clone() alg_len() is renamed to xfrm_alg_len() because of its global exposition.

2008-01-09[NET]: Clone the sk_buff 'iif' field in __skb_clone()Paul Moore
Both NetLabel and SELinux (other LSMs may grow to use it as well) rely on the 'iif' field to determine the receiving network interface of inbound packets. Unfortunately, at present this field is not preserved across a skb clone operation which can lead to garbage values if the cloned skb is sent back through the network stack. This patch corrects this problem by properly copying the 'iif' field in __skb_clone() and removing the 'iif' field assignment from skb_act_clone() since it is no longer needed. Also, while we are here, put the assignments in the same order as the offsets to reduce cacheline bounces. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

2008-01-04[X25]: Add missing x25_neigh_putJulia Lawall
The function x25_get_neigh increments a reference count. At the point of the second goto out, the result of calling x25_get_neigh is only stored in a local variable, and thus no one outside the function will be able to decrease the reference count. Thus, x25_neigh_put should be called before the return in this case. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * if ((E = x25_get_neigh(...)) == NULL) S ... when != x25_neigh_put(...,(T1)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != x25_neigh_put(...,(T2)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2007-12-30[TCP]: use non-delayed ACK for congestion control RTTGavin McCullagh
When a delayed ACK representing two packets arrives, there are two RTT samples available, one for each packet. The first (in order of seq number) will be artificially long due to the delay waiting for the second packet, the second will trigger the ACK and so will not itself be delayed. According to rfc1323, the SRTT used for RTO calculation should use the first rtt, so receivers echo the timestamp from the first packet in the delayed ack. For congestion control however, it seems measuring delayed ack delay is not desirable as it varies independently of congestion. The patch below causes seq_rtt and last_ackt to be updated with any available later packet rtts which should have less (and hopefully zero) delack delay. The rtt value then gets passed to ca_ops->pkts_acked(). Where TCP_CONG_RTT_STAMP was set, effort was made to supress RTTs from within a TSO chunk (!fully_acked), using only the final ACK (which includes any TSO delay) to generate RTTs. This patch removes these checks so RTTs are passed for each ACK to ca_ops->pkts_acked(). For non-delay based congestion control (cubic, h-tcp), rtt is sometimes used for rtt-scaling. In shortening the RTT, this may make them a little less aggressive. Delay-based schemes (eg vegas, veno, illinois) should get a cleaner, more accurate congestion signal, particularly for small cwnds. The congestion control module can potentially also filter out bad RTTs due to the delayed ack alarm by looking at the associated cnt which (where delayed acking is in use) should probably be 1 if the alarm went off or greater if the ACK was triggered by a packet.

2007-12-28[IPV4] Fix ip=dhcp regressionSimon Horman
David Brownell pointed out a regression in my recent "Fix ip command line processing" patch. It turns out to be a fairly blatant oversight on my part whereby ic_enable is never set, and thus autoconfiguration is never enabled. Clearly my testing was broken :-( The solution that I have is to set ic_enable to 1 if we hit ip_auto_config_setup(), which basically means that autoconfiguration is activated unless told otherwise. I then flip ic_enable to 0 if ip=off, ip=none, ip=::::::off or ip=::::::none using ic_proto_name(); The incremental patch is below, let me know if a non-incremental version is prepared, as I did as for the original patch to be reverted pending a fix.

2007-12-20[IPSEC]: Avoid undefined shift operation when testing algorithm IDHerbert Xu
The aalgos/ealgos fields are only 32 bits wide. However, af_key tries to test them with the expression 1 << id where id can be as large as 253. This produces different behaviour on different architectures. The following patch explicitly checks whether ID is greater than 31 and fails the check if that's the case. We cannot easily extend the mask to be longer than 32 bits due to exposure to user-space. Besides, this whole interface is obsolete anyway in favour of the xfrm_user interface which doesn't use this bit mask in templates (well not within the kernel anyway).

2007-12-20mac80211: fix header opsJohannes Berg
When using recvfrom() on a SOCK_DGRAM packet socket, I noticed that the MAC address passed back for wireless frames was always completely wrong. The reason for this is that the header parse function assigned to our virtual interfaces is a function parsing an 802.11 rather than 802.3 header. This patch fixes it by keeping the default ethernet header operations assigned. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

While testing the mcs7780 based IrDA USB dongle I've stumbled upon memory leak in irlmp_unregister_link(). Hashbin for lsaps is created in irlmp_register_link and should probably be freed in irlmp_unregister_link().
