2012-05-10codel: Controlled Delay AQMEric Dumazet
An implementation of CoDel AQM, from Kathleen Nichols and Van Jacobson. http://queue.acm.org/detail.cfm?id=2209336 This AQM main input is no longer queue size in bytes or packets, but the delay packets stay in (FIFO) queue. As we don't have infinite memory, we still can drop packets in enqueue() in case of massive load, but mean of CoDel is to drop packets in dequeue(), using a control law based on two simple parameters : target : target sojourn time (default 5ms) interval : width of moving time window (default 100ms) Based on initial work from Dave Taht. Refactored to help future codel inclusion as a plugin for other linux qdisc (FQ_CODEL, ...), like RED. include/net/codel.h contains codel algorithm as close as possible than Kathleen reference. net/sched/sch_codel.c contains the linux qdisc specific glue. Separate structures permit a memory efficient implementation of fq_codel (to be sent as a separate work) : Each flow has its own struct codel_vars. timestamps are taken at enqueue() time with 1024 ns precision, allowing a range of 2199 seconds in queue, and 100Gb links support. iproute2 uses usec as base unit. Selected packets are dropped, unless ECN is enabled and packets can get ECN mark instead. Tested from 2Mb to 10Gb speeds with no particular problems, on ixgbe and tg3 drivers (BQL enabled). Usage: tc qdisc ... codel [ limit PACKETS ] [ target TIME ] [ interval TIME ] [ ecn ] qdisc codel 10: parent 1:1 limit 2000p target 3.0ms interval 60.0ms ecn Sent 13347099587 bytes 8815805 pkt (dropped 0, overlimits 0 requeues 0) rate 202365Kbit 16708pps backlog 113550b 75p requeues 0 count 116 lastcount 98 ldelay 4.3ms dropping drop_next 816us maxpacket 1514 ecn_mark 84399 drop_overlimit 0 CoDel must be seen as a base module, and should be used keeping in mind there is still a FIFO queue. So a typical setup will probably need a hierarchy of several qdiscs and packet classifiers to be able to meet whatever constraints a user might have. One possible example would be to use fq_codel, which combines Fair Queueing and CoDel, in replacement of sfq / sfq_red.

2012-05-10l2tp: fix data packet sequence number handlingJames Chapman
If enabled, L2TP data packets have sequence numbers which a receiver can use to drop out of sequence frames or try to reorder them. The first frame has sequence number 0, but the L2TP code currently expects it to be 1. This results in the first data frame being handled as out of sequence. This one-line patch fixes the problem.

2012-05-10l2tp: fix reorder timeout recoveryJames Chapman
When L2TP data packet reordering is enabled, packets are held in a queue while waiting for out-of-sequence packets. If a packet gets lost, packets will be held until the reorder timeout expires, when we are supposed to then advance to the sequence number of the next packet but we don't currently do so. As a result, the data channel is stuck because we are waiting for a packet that will never arrive - all packets age out and none are passed. The fix is to add a flag to the session context, which is set when the reorder timeout expires and tells the receive code to reset the next expected sequence number to that of the next packet in the queue. Tested in a production L2TP network with Starent and Nortel L2TP gear. Signed-off-by: James Chapman <jchapman@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This reverts commit 8a83a00b0735190384a348156837918271034144. It causes regressions for S390 devices, because it does an unconditional DST drop on SKBs for vlans and the QETH device needs the neighbour entry hung off the DST for certain things on transmit.

2012-05-10vfs: make it possible to access the dentry hash/len as one 64-bit entryLinus Torvalds
This allows comparing hash and len in one operation on 64-bit architectures. Right now only __d_lookup_rcu() takes advantage of this, since that is the case we care most about. The use of anonymous struct/unions hides the alternate 64-bit approach from most users, the exception being a few cases where we initialize a 'struct qstr' with a static initializer. This makes the problematic cases use a new QSTR_INIT() helper function for that (but initializing just the name pointer with a "{ .name = xyzzy }" initializer remains valid, as does just copying another qstr structure).

2012-05-09netfilter: hashlimit: byte-based limit modeFlorian Westphal
can be used e.g. for ingress traffic policing or to detect when a host/port consumes more bandwidth than expected. This is done by optionally making cost to mean "cost per 16-byte-chunk-of-data" instead of "cost per packet".

2012-05-09netfilter: add xt_hmark target for hash-based skb markingHans Schillstrom
The target allows you to create rules in the "raw" and "mangle" tables which set the skbuff mark by means of hash calculation within a given range. The nfmark can influence the routing method (see "Use netfilter MARK value as routing key") and can also be used by other subsystems to change their behaviour.

2012-05-09netfilter: ip6_tables: add flags parameter to ipv6_find_hdr()Hans Schillstrom
This patch adds the flags parameter to ipv6_find_hdr. This flags allows us to: * know if this is a fragment. * stop at the AH header, so the information contained in that header can be used for some specific packet handling. This patch also adds the offset parameter for inspection of one inner IPv6 header that is contained in error messages.

2012-05-09Bluetooth: Refactor L2CAP ERTM and streaming transmit segmentationMat Martineau
Use more common code for ERTM and streaming mode segmentation and transmission, and begin using skb control block data for delaying extended or enhanced header generation until just before the packet is transmitted. This code is also better suited for resegmentation, which is needed when L2CAP links are reconfigured after an AMP channel move.
