* ipv6: Copy cork options in ip6_append_dataHerbert Xu2009-02-051-15/+52

* udp: Fix UDP short packet false positiveJesper Dangaard Brouer2009-02-051-1/+2
| | | | | | | | | | | | | The UDP header pointer assignment must happen after calling pskb_may_pull(). As pskb_may_pull() can potentially alter the SKB buffer. This was exposted by running multicast traffic through the NIU driver, as it won't prepull the protocol headers into the linear area on receive.

These definitions are always needed if debug is enabled at compile time (independently of DEBUG_FS being or not enabled), so moving them to a file that is always compiled fixes the issue.

This caused the kernel panic. if (abs_offset < block_limit) { - *data = st->cur_skb->data + abs_offset; + *data = st->cur_skb->data + (abs_offset - st->stepped_offset); I enabled the debug_tcp and with a few printks found that the code did not go to the next_skb label and could find that the sequence being followed was this - It hit this if condition - if (st->cur_skb->next) { st->cur_skb = st->cur_skb->next; st->frag_idx = 0; goto next_skb; And so, now the st pointer is shifted to the next skb whereas actually it should have hit the second else if first since the data is in the frag_list. else if (st->root_skb == st->cur_skb && skb_shinfo(st->root_skb)->frag_list) { st->cur_skb = skb_shinfo(st->root_skb)->frag_list; goto next_skb; } Reversing the two conditions the attached patch fixes the issue for me on top of Herbert's patches.

* | tcp: Fix length tcp_splice_data_recv passes to skb_splice_bits.Dimitris Michailidis2009-01-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tcp_splice_data_recv has two lengths to consider: the len parameter it gets from tcp_read_sock, which specifies the amount of data in the skb, and rd_desc->count, which is the amount of data the splice caller still wants. Currently it passes just the latter to skb_splice_bits, which then splices min(rd_desc->count, skb->len - offset) bytes. Most of the time this is fine, except when the skb contains urgent data. In that case len goes only up to the urgent byte and is less than skb->len - offset. By ignoring len tcp_splice_data_recv may a) splice data tcp_read_sock told it not to, b) return to tcp_read_sock a value > len. Now, tcp_read_sock doesn't handle used > len and leaves the socket in a bad state (both sk_receive_queue and copied_seq are bad at that point) resulting in duplicated data and corruption. Fix by passing min(rd_desc->count, len) to skb_splice_bits. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Acked-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

|/ | | | | | | | | | | | | | | | | | | | | commit 9088c5609584684149f3fb5b065aa7f18dcb03ff (udp: Improve port randomization) introduced a regression for UDP bind() syscall to null port (getting a random port) in case lot of ports are already in use. This is because we do about 28000 scans of very long chains (220 sockets per chain), with many spin_lock_bh()/spin_unlock_bh() calls. Fix this using a bitmap (64 bytes for current value of UDP_HTABLE_SIZE) so that we scan chains at most once.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * gro: Fix merging of paged packetsHerbert Xu2009-01-201-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | The previous fix to paged packets broke the merging because it reset the skb->len before we added it to the merged packet. This wasn't detected because it simply resulted in the truncation of the packet while the missing bit is subsequently retransmitted. The fix is to store skb->len before we clobber it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The country IE number of channels on 5 GHz specifies the number of 5 GHz channels, not the number of sequential channel numbers. For example, if in a country IEs if the first channel given is 36 and the number of channels passed is 4 then the individual channel numbers defined for the 5 GHz PHY by these parameters are: 36, 40, 44, 48 not: 36, 37, 38, 39 See: http://tinyurl.com/11d-clarification Signed-off-by: Luis R.

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 Poplawski2009-01-191-32/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
