2008-07-21netfilter: nf_nat_sip: c= is optional for sessionHerbert Xu
According to RFC2327, the connection information is optional in the session description since it can be specified in the media description instead. My provider does exactly that and does not provide any connection information in the session description. As a result the new kernel drops all invite responses.

2008-07-21netfilter: accounting rework: ct_extend + 64bit counters (v4)Krzysztof Piotr Oledzki
Initially netfilter has had 64bit counters for conntrack-based accounting, but it was changed in 2.6.14 to save memory. Unfortunately in-kernel 64bit counters are still required, for example for "connbytes" extension. However, 64bit counters waste a lot of memory and it was not possible to enable/disable it runtime. This patch: - reimplements accounting with respect to the extension infrastructure, - makes one global version of seq_print_acct() instead of two seq_print_counters(), - makes it possible to enable it at boot time (for CONFIG_SYSCTL/CONFIG_SYSFS=n), - makes it possible to enable/disable it at runtime by sysctl or sysfs, - extends counters from 32bit to 64bit, - renames ip_conntrack_counter -> nf_conn_counter, - enables accounting code unconditionally (no longer depends on CONFIG_NF_CT_ACCT), - set initial accounting enable state based on CONFIG_NF_CT_ACCT - removes buggy IPCT_COUNTER_FILLING event handling. If accounting is enabled newly created connections get additional acct extend. Old connections are not changed as it is not possible to add a ct_extend area to confirmed conntrack. Accounting is performed for all connections with acct extend regardless of a current state of "net.netfilter.nf_conntrack_acct".

2008-07-21hdlcdrv: Fix CRC calculation.Micah Dowty
This is a trivial patch against the hdlcdrv module that fixes its CRC calculation. The finished CRC was overwriting the first two bytes of each packet rather than being appended to the end. I've tested this with 2.6.8 and 2.6.10-rc1, but hdlcdrv hasn't changed much recently so it should work with many other kernel versions.

2008-07-21atl1: Do not wake queue before queue has been started.David S. Miller
Based upon a bug report by Alexey Dobriyan, the patch is also tested by him and confirmed to fix the problem. Packet flow during link state events should not be done by waking and stopping the TX queue anyways, that is handled transparently by netif_carrier_{on,off}(). So, remove the netif_{wake,stop}_queue() calls in the link check code, and add the necessary netif_start_queue() call to atl1_up(). Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-21dm: introduce merge_bvec_fnMilan Broz
Introduce a bvec merge function for device mapper devices for dynamic size restrictions. This code ensures the requested biovec lies within a single target and then calls a target-specific function to check against any constraints imposed by underlying devices.

2008-07-21dm snapshot: use per device mempoolsMikulas Patocka
Change snapshot per-module mempool to per-device mempool. Per-module mempools could cause a deadlock if multiple snapshot devices are stacked above each other. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-07-21dm snapshot: fix race during exception creationMikulas Patocka
Fix a race condition that returns incorrect data when a write causes an exception to be allocated whilst a read is still in flight. The race condition happens as follows: * A read to non-reallocated sector in the snapshot is submitted so that the read is routed to the original device. * A write to the original device is submitted. The write causes an exception that reallocates the block. The write proceeds. * The original read is dequeued and reads the wrong data. This race can be triggered with CFQ scheduler and one thread writing and multiple threads reading simultaneously. (This patch relies upon the earlier dm-kcopyd-per-device.patch to avoid a deadlock.)

2008-07-21dm snapshot: track snapshot readsMikulas Patocka
Whenever a snapshot read gets mapped through to the origin, track it in a per-snapshot hash table indexed by chunk number, using memory allocated from a new per-snapshot mempool. We need to track these reads to avoid race conditions which will be fixed by patches that follow.

The problem is that 'push' will default to 32-bit, which is not wide enough as a fixup address. (and which would crash on any real fixup event even if it was wide enough) Introduce KVM_EX_PUSH to get the proper address push width on 64-bit too. Signed-off-by: Ingo Molnar <mingo@elte.hu>
