| * vlan: Export symbols as non GPL symbols.Ben Greear2009-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In previous kernels, any kernel module could get access to the 'real-device' and the VLAN-ID for a particular VLAN. In more recent kernels, the code was restructured such that this is hard to do without accessing private .h files for any module that cannot use GPL-only symbols. Attached is a patch to once again allow non-GPL modules the ability to access the real-device and VLAN id for VLANs.

| * sctp: Fix another socket race during accept/peeloffVlad Yasevich2009-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race between sctp_rcv() and sctp_accept() where we have moved the association from the listening socket to the accepted socket, but sctp_rcv() processing cached the old socket and continues to use it. The easy solution is to check for the socket mismatch once we've grabed the socket lock. If we hit a mis-match, that means that were are currently holding the lock on the listening socket, but the association is refrencing a newly accepted socket. We need to drop the lock on the old socket and grab the lock on the new one. A more proper solution might be to create accepted sockets when the new association is established, similar to TCP. That would eliminate the race for 1-to-1 style sockets, but it would still existing for 1-to-many sockets where a user wished to peeloff an association. For now, we'll live with this easy solution as it addresses the problem.

| * sctp: Properly timestamp outgoing data chunks for rtx purposesVlad Yasevich2009-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes to the retransmit code exposed a long standing bug where it was possible for a chunk to be time stamped after the retransmit timer was reset. This caused a rare situation where the retrnamist timer has expired, but nothing was marked for retrnasmission because all of timesamps on data were less then 1 rto ago. As result, the timer was never restarted since nothing was retransmitted, and this resulted in a hung association that did couldn't complete the data transfer. The solution is to timestamp the chunk when it's added to the packet for transmission purposes. After the packet is trsnmitted the rtx timer is restarted. This guarantees that when the timer expires, there will be data to retransmit. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The issue is that IEEE-802.11 allows APs to send a subset of what a country regulatory domain defines. This was clarified in this document: http://tinyurl.com/11d-clarification As such it is possible, and this is what is done in practice, that a single band 2.4 GHz AP will only send 2.4 GHz band regulatory information through the 802.11 country information element and then the current intersection with what CRDA provided yields a regulatory domain with no 5 GHz information -- even though that country may actually allow 5 GHz operation. We correct this by only applying the intersection rules on a channel if the the intersection yields a regulatory rule on the same band the channel is on. Signed-off-by: Luis R.

| * | net: Fix data corruption when splicing from sockets.Jarek Poplawski2009-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trick in socket splicing where we try to convert the skb->data into a page based reference using virt_to_page() does not work so well. The idea is to pass the virt_to_page() reference via the pipe buffer, and refcount the buffer using a SKB reference. But if we are splicing from a socket to a socket (via sendpage) this doesn't work. The from side processing will grab the page (and SKB) references. The sendpage() calls will grab page references only, return, and then the from side processing completes and drops the SKB ref. The page based reference to skb->data is not enough to keep the kmalloc() buffer backing it from being reused. Yet, that is all that the socket send side has at this point. This leads to data corruption if the skb->data buffer is reused by SLAB before the send side socket actually gets the TX packet out to the device. The fix employed here is to simply allocate a page and copy the skb->data bytes into that page. This will hurt performance, but there is no clear way to fix this properly without a copy at the present time, and it is important to get rid of the data corruption. With fixes from Herbert Xu.

| * tcp: splice as many packets as possible at onceWilly Tarreau2009-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As spotted by Willy Tarreau, current splice() from tcp socket to pipe is not optimal. It processes at most one segment per call. This results in low performance and very high overhead due to syscall rate when splicing from interfaces which do not support LRO. Willy provided a patch inside tcp_splice_read(), but a better fix is to let tcp_read_sock() process as many segments as possible, so that tcp_rcv_space_adjust() and tcp_cleanup_rbuf() are called less often. With this change, splice() behaves like tcp_recvmsg(), being able to consume many skbs in one system call. With typical 1460 bytes of payload per frame, that means splice(SPLICE_F_NONBLOCK) can return 16*1460 = 23360 bytes.

Therefore rate_lowest_index returns 4 (= 6Mbit, instead of usual 0 = 1Mbit). Since mi->r array is initialized with zeros in minstrel_alloc_sta, rix_to_ndx has a hard time to find the 6Mbit entry and will trigged the WARNING.

| * | pkt_sched: sch_htb: Break all htb_do_events() after 2 jiffiesJarek Poplawski2009-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently htb_do_events() breaks events recounting for a level after 2 jiffies, but there is no reason to repeat this for next levels and increase delays even more (with softirqs disabled). htb_dequeue_tree() can add to this too, btw. In such a case q->now time is invalid anyway. Thanks to Patrick McHardy for spotting an error around earlier version of this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Next event time should consider jiffies used for recounting. Otherwise qdisc_watchdog_schedule() triggers hrtimer immediately with the event in the past, and may cause very high ksoftirqd cpu usage (if highres is on). There is also removed checking "event" for zero in htb_dequeue(): it's always true in this place. Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S.

The VLAN tag and the PPPOE session ID are an integral part of the packet flow information, yet they're completely ignored by the bridge netfilter. This is potentially a security hole as it treats all VLANs and PPPOE sessions as the same. What's more, it's actually broken for PPPOE as the bridge netfilter tries to trim the packets to the IP length without adjusting the PPPOE header (and adjusting the PPPOE header isn't much better since the PPPOE peer may require the padding to be present). Therefore we should disable this by default. It does mean that people relying on this feature may lose networking depending on how their bridge netfilter rules are configured. However, IMHO the problems this code causes are serious enough to warrant this.

* | 9p: disallow RDMA if RDMA CM isn't availableRoland Dreier2009-01-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If INET=y and INFINIBAND=y, but IPV6=m then INFINIBAND_ADDR_TRANS is set to n and the RDMA CM functions rdma_connect() et al are not built. However, the current config dependencies allow NET_9P_RDMA to be selected in this, which leads to a build failure. Fix this by adding a dependency on INFINIBAND_ADDR_TRANS to disallow NET_9P_RDMA in this case.
