2010-02-22af_key: locking changestephen hemminger1-60/+16
Get rid of custom locking that was using wait queue, lock, and atomic to basically build a queued mutex. Use RCU for read side. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-22packet: convert socket list to RCU (v3)stephen hemminger3-33/+43
Convert AF_PACKET to use RCU, eliminating one more reader/writer lock. There is no need for a real sk_del_node_init_rcu(), because sk_del_node_init is doing the equivalent thing to hlst_del_init_rcu already; but added some comments to try and make that obvious.

2010-02-22isdn: fix a few Kconfig imperfectionsTilman Schmidt2-22/+28
1. Rewrite the outdated help texts for config options ISDN and ISDN_CAPI. 2. The MISDN config option appeared between ISDN_I4L and the I4L hardware driver options; move it to a less irritating place. 3. HYSDN is not in fact an I4L driver, and needn't depend on ISDN_I4L, so move it from the I4L section to the general section. 4. ISDN_HDLC is now also used by drivers outside I4L. Move it from the I4L section to the general section, too. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-02-22ixgbe: prevent speculative processing of descriptors before readyMilton Miller1-0/+1
The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it.

2010-02-19r8169: enable 64-bit DMA by default for PCI Express devices (v2)Robert Hancock1-7/+14
Currently use of 64-bit DMA is disabled in r8169 unless the user passes the use_dac module option. This is reasonable for conventional PCI devices where broken chipsets may not handle dual-address-cycle transfers properly for 32-bit slots and so this may not be safe. However, PCI Express should not have this problem and not using 64-bit DMA results in DMA transfers needlessly using the IOMMU or SWIOTLB. Set the use_dac module parameter to a new default value of -1 which results in 64-bit DMA being enabled by default for PCI Express devices only.

2010-02-19mlx4: replace the dma_sync_single_range_for_cpu/device APIFUJITA Tomonori1-4/+4
There are only two users of the dma_sync_single_range_for_cpu/device API in mainline (mlx4 and ssb). The dma_sync_single_range_for_cpu/device API has never been documented and the dma_sync_single_for_cpu/device API also support a partial sync. This converts mlx4 to use the dma_sync_single_for_cpu/device API (preparations for the removal of the dma_sync_single_range_for_cpu/device API).

To see the effect make sure you have an empty SPD. On window1 "ip xfrm mon" and on window2 issue "ip xfrm policy flush" You get prompt back in window2 and you see the flush event on window1.

2010-02-19pfkey: fix SA and SP flush sequenceJamal Hadi Salim1-6/+27
RFC 2367 says flushing behavior should be: 1) user space -> kernel: flush 2) kernel: flush 3) kernel -> user space: flush event to ALL listeners This is not realistic today in the presence of selinux policies which may reject the flush etc. So we make the sequence become: 1) user space -> kernel: flush 2) kernel: flush 3) kernel -> user space: flush response to originater from #1 4) if there were no errors then: kernel -> user space: flush event to ALL listeners Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S.

2010-02-19netfilter: ctnetlink: fix creation of conntrack with helpersPablo Neira Ayuso1-11/+11
This patch fixes a bug that triggers an assertion if you create a conntrack entry with a helper and netfilter debugging is enabled. Basically, we hit the assertion because the confirmation flag is set before the conntrack extensions are added. To fix this, we move the extension addition before the aforementioned flag is set. This patch also removes the possibility of setting a helper for existing conntracks. This operation would also trigger the assertion since we are not allowed to add new extensions for existing conntracks. We know noone that could benefit from this operation sanely. Thanks to Eric Dumazet for initial posting a preliminary patch to address this issue.

Due to lack of time, space, motivation, hardware and probably expertise, I have reluctantly decided to orphan the DECnet code in the kernel.

2010-02-18net: TCP thin dupackAndreas Petlund6-1/+42
This patch enables fast retransmissions after one dupACK for TCP if the stream is identified as thin. This will reduce latencies for thin streams that are not able to trigger fast retransmissions due to high packet interarrival time.

This patch will make TCP use only linear timeouts if the stream is thin. This will help to avoid the very high latencies that thin stream suffer because of exponential backoff. This mechanism is only active if enabled by iocontrol or syscontrol and the stream is identified as thin. A maximum of 6 linear timeouts is tried before exponential backoff is resumed.
