| * gro: Fix illegal merging of trailer trashHerbert Xu2009-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we've merged skb's with page frags, and subsequently receive a trailer skb (< MSS) that is not completely non-linear (this can occur on Intel NICs if the packet size falls below the threshold), GRO ends up producing an illegal GSO skb with a frag_list. This is harmless unless the skb is then forwarded through an interface that requires software GSO, whereupon the GSO code will BUG. This patch detects this case in GRO and avoids merging the trailer skb. Reported-by: Mark Wagner <mwagner@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic Mode is the default mode of operation of a L2CAP entity. In this case the RFC (Retransmission and Flow Control) configuration option should not be used at all. Normally remote L2CAP implementation should just ignore this option, but it can cause various side effects with other Bluetooth stacks that are not capable of handling unknown options.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent commit 8da645e101a8c20c6073efda3c7cc74eec01b87f sctp: Get rid of an extra routing lookup when adding a transport introduced a regression in the connection setup. The behavior was different between IPv4 and IPv6. IPv4 case ended up working because the route lookup routing returned a NULL route, which triggered another route lookup later in the output patch that succeeded. In the IPv6 case, a valid route was returned for first call, but we could not find a valid source address at the time since the source addresses were not set on the association yet. Thus resulted in a hung connection. The solution is to set the source addresses on the association prior to adding peers.

| * ipip: Fix handling of DF packets when pmtudisc is OFFHerbert Xu2009-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC 2003 requires the outer header to have DF set if DF is set on the inner header, even when PMTU discovery is off for the tunnel. Our implementation does exactly that. For this to work properly the IPIP gateway also needs to engate in PMTU when the inner DF bit is set. As otherwise the original host would not be able to carry out its PMTU successfully since part of the path is only visible to the gateway. Unfortunately when the tunnel PMTU discovery setting is off, we do not collect the necessary soft state, resulting in blackholes when the original host tries to perform PMTU discovery. This problem is not reproducible on the IPIP gateway itself as the inner packet usually has skb->local_df set. This is not correctly cleared (an unrelated bug) when the packet passes through the tunnel, which allows fragmentation to occur. For hosts behind the IPIP gateway it is readily visible with a simple ping. This patch fixes the problem by performing PMTU discovery for all packets with the inner DF bit set, regardless of the PMTU discovery setting on the tunnel itself.

| * netfilter: nf_nat: fix NAT issue in 2.6.30.4+Jozsef Kadlecsik2009-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Vitezslav Samel discovered that since 2.6.30.4+ active FTP can not work over NAT. The "cause" of the problem was a fix of unacknowledged data detection with NAT (commit a3a9f79e361e864f0e9d75ebe2a0cb43d17c4272). However, actually, that fix uncovered a long standing bug in TCP conntrack: when NAT was enabled, we simply updated the max of the right edge of the segments we have seen (td_end), by the offset NAT produced with changing IP/port in the data. However, we did not update the other parameter (td_maxend) which is affected by the NAT offset. Thus that could drift away from the correct value and thus resulted breaking active FTP. The patch below fixes the issue by *not* updating the conntrack parameters from NAT, but instead taking into account the NAT offsets in conntrack in a consistent way. (Updating from NAT would be more harder and expensive because it'd need to re-calculate parameters we already calculated in conntrack.)

I'm not sure what people think of my co-opting of fid->aux here. I'd be happy to rework if there's a better way. When the size of the user supplied buffer passed to readdir is smaller than the data returned in one go by the 9P read request, v9fs_dir_readdir() currently discards extra data so that, on the next call, a 9P read request will be issued with offset < previous offset + bytes returned, which voilates the constraint described in paragraph 3 of read(5) description.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently PACKET_TX_RING forces certain amount of every frame to remain unused. This probably originates from an early version of the PACKET_TX_RING patch that in fact used the extra space when the (since removed) CONFIG_PACKET_MMAP_ZERO_COPY option was enabled. The current code does not make any use of this extra space. This patch removes the extra space reservation and lets userspace make use of the full frame size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Augment raw_send_hdrinc to correct for incorrect ip header length values A series of oopses was reported to me recently. Apparently when using AF_RAW sockets to send data to peers that were reachable via ipsec encapsulation, people could panic or BUG halt their systems. I've tracked the problem down to user space sending an invalid ip header over an AF_RAW socket with IP_HDRINCL set to 1. Basically what happens is that userspace sends down an ip frame that includes only the header (no data), but sets the ip header ihl value to a large number, one that is larger than the total amount of data passed to the sendmsg call. In raw_send_hdrincl, we allocate an skb based on the size of the data in the msghdr that was passed in, but assume the data is all valid. Later during ipsec encapsulation, xfrm4_tranport_output moves the entire frame back in the skbuff to provide headroom for the ipsec headers. During this operation, the skb->transport_header is repointed to a spot computed by skb->network_header + the ip header length (ihl). Since so little data was passed in relative to the value of ihl provided by the raw socket, we point transport header to an unknown location, resulting in various crashes. This fix for this is pretty straightforward, simply validate the value of of iph->ihl when sending over a raw socket. If (iph->ihl*4U) > user data buffer size, drop the frame and return -EINVAL. I just confirmed this fixes the reported crashes. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

| * mac80211: fix for incorrect sequence number on hostapd injected framesBjörn Smedman2009-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When hostapd injects a frame, e.g. an authentication or association response, mac80211 looks for a suitable access point virtual interface to associate the frame with based on its source address. This makes it possible e.g. to correctly assign sequence numbers to the frames. A small typo in the ethernet address comparison statement caused a failure to find a suitable ap interface. Sequence numbers on such frames where therefore left unassigned causing some clients (especially windows-based 11b/g clients) to reject them and fail to authenticate or associate with the access point. This patch fixes the typo in the address comparison statement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When the in-kernel SME gets an association failure from the AP we don't deauthenticate, and thus get into a very confused state which will lead to warnings later on. Fix this by actually deauthenticating when the AP indicates an association failure.

| * mac80211: fix ibss joiningReinette Chatre2009-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent commit "mac80211: fix logic error ibss merge bssid check" fixed joining of ibss cell when static bssid is provided. In this case ifibss->bssid is set before the cell is joined and comparing that address to a bss should thus always succeed. Unfortunately this change broke the other case of joining a ibss cell without providing a static bssid where the value of ifibss->bssid is not set before the cell is joined. Since ifibss->bssid may be set before or after joining the cell we do not learn anything by comparing it to a known bss. Remove this check.

| | | | | | | | | | | | | | | | | | | | | | | | While playing with pktgen, I realized IP ID was not filled and a random value was taken, possibly leaking 2 bytes of kernel memory.

| * net: use WARN() for the WARN_ON in commit b6b39e8f3fbbbArjan van de Ven2009-10-23
| | | | | | | | | | | | | | | | | | | | | | | | Commit b6b39e8f3fbbb (tcp: Try to catch MSG_PEEK bug) added a printk() to the WARN_ON() that's in tcp.c. This patch changes this combination to WARN(); the advantage of WARN() is that the printk message shows up inside the message, so that kerneloops.org will collect the message. In addition, this gets rid of an extra if() statement. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

While the change itself is a very good one, it can break userspace applications. For example if a userspace tool wanted to get the ID of virtio_net it used to include virtio_net.h. This does no longer work, since virtio_net.h does not include virtio_ids.h. This patch moves all "#include <linux/virtio_ids.h>" from the C files into the header files, making the header files compatible with the old ones. In addition, this patch exports virtio_ids.h to userspace.
