2012-05-02tcp: change tcp_adv_win_scale and tcp_rmem[2]Eric Dumazet1-2/+2
tcp_adv_win_scale default value is 2, meaning we expect a good citizen skb to have skb->len / skb->truesize ratio of 75% (3/4) In 2.6 kernels we (mis)accounted for typical MSS=1460 frame : 1536 + 64 + 256 = 1856 'estimated truesize', and 1856 * 3/4 = 1392. So these skbs were considered as not bloated. With recent truesize fixes, a typical MSS=1460 frame truesize is now the more precise : 2048 + 256 = 2304. But 2304 * 3/4 = 1728. So these skb are not good citizen anymore, because 1460 < 1728 (GRO can escape this problem because it build skbs with a too low truesize.) This also means tcp advertises a too optimistic window for a given allocated rcvspace : When receiving frames, sk_rmem_alloc can hit sk_rcvbuf limit and we call tcp_prune_queue()/tcp_collapse() too often, especially when application is slow to drain its receive queue or in case of losses (netperf is fast, scp is slow). This is a major latency source. We should adjust the len/truesize ratio to 50% instead of 75% This patch : 1) changes tcp_adv_win_scale default to 1 instead of 2 2) increase tcp_rmem[2] limit from 4MB to 6MB to take into account better truesize tracking and to allow autotuning tcp receive window to reach same value than before. Note that same amount of kernel memory is consumed compared to 2.6 kernels.

2012-05-01USB: Add driver for NXP ISP1301 USB transceiverRoland Stigge1-0/+25
This new driver registers the NXP ISP1301 chip via the I2C subsystem. The chip is the USB transceiver shared by ohci-nxp, lpc32xx_udc (gadget) and isp1301_omap. ISP1301 is a very low-level driver that primarily separates out the I2C client registration of the ISP1301 chip (including instantiation via DT), used by other drivers, and declares the chip's registers. It's only a helper driver for some OHCI and USB device drivers. The driver can be considered as a register set extension of ohci-nxp, lpc32xx-udc and isp1301_omap, which in turn know best what to do with the low level functionality (individual ISP1301 registers and timing, see the different initialization strategies in those drivers). Those drivers previously internally duplicated ISP1301 register definitions which is solved by this new isp1301 driver. The ISP1301 registers exposed via isp1301.h can be accessed by other drivers using it with standard i2c_smbus_*() accesses. Following patches let the respective USB host and gadget drivers use this driver, instead of duplicating ISP1301 handling.

Pull networking updates from David Miller: 1) Fix inaccuracies in network driver interface documentation, from Ben Hutchings. 2) Fix handling of negative offsets in BPF JITs, from Jan Seiffert. 3) Compile warning, locking, and refcounting fixes in netfilter's xt_CT, from Pablo Neira Ayuso. 4) phonet sendmsg needs to validate user length just like any other datagram protocol, fix from Sasha Levin. 5) Ipv6 multicast code uses wrong loop index, from RongQing Li. 6) Link handling and firmware fixes in bnx2x driver from Yaniv Rosner and Yuval Mintz. 7) mlx4 erroneously allocates 4 pages at a time, regardless of page size, fix from Thadeu Lima de Souza Cascardo. 8) SCTP socket option wasn't extended in a backwards compatible way, fix from Thomas Graf. 9) Add missing address change event emissions to bonding, from Shlomo Pongratz. 10) /proc/net/dev regressed because it uses a private offset to track where we are in the hash table, but this doesn't track the offset pullback that the seq_file code does resulting in some entries being missed in large dumps. Fix from Eric Dumazet. 11) do_tcp_sendpage() unloads the send queue way too fast, because it invokes tcp_push() when it shouldn't. Let the natural sequence generated by the splice paths, and the assosciated MSG_MORE settings, guide the tcp_push() calls. Otherwise what goes out of TCP is spaghetti and doesn't batch effectively into GSO/TSO clusters. From Eric Dumazet. 12) Once we put a SKB into either the netlink receiver's queue or a socket error queue, it can be consumed and freed up, therefore we cannot touch it after queueing it like that. Fixes from Eric Dumazet. 13) PPP has this annoying behavior in that for every transmit call it immediately stops the TX queue, then calls down into the next layer to transmit the PPP frame. But if that next layer can take it immediately, it just un-stops the TX queue right before returning from the transmit method. Besides being useless work, it makes several facilities unusable, in particular things like the equalizers. Well behaved devices should only stop the TX queue when they really are full, and in PPP's case when it gets backlogged to the downstream device. David Woodhouse therefore fixed PPP to not stop the TX queue until it's downstream can't take data any more. 14) IFF_UNICAST_FLT got accidently lost in some recent stmmac driver changes, re-add. From Marc Kleine-Budde. 15) Fix link flaps in ixgbe, from Eric W. Multanen. 16) Descriptor writeback fixes in e1000e from Matthew Vick. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (47 commits) net: fix a race in sock_queue_err_skb() netlink: fix races after skb queueing doc, net: Update ndo_start_xmit return type and values doc, net: Remove instruction to set net_device::trans_start doc, net: Update netdev operation names doc, net: Update documentation of synchronisation for TX multiqueue doc, net: Remove obsolete reference to dev->poll ethtool: Remove exception to the requirement of holding RTNL lock MAINTAINERS: update for Marvell Ethernet drivers bonding: properly unset current_arp_slave on slave link up phonet: Check input from user before allocating tcp: tcp_sendpages() should call tcp_push() once ipv6: fix array index in ip6_mc_add_src() mlx4: allocate just enough pages instead of always 4 pages stmmac: re-add IFF_UNICAST_FLT for dwmac1000 bnx2x: Clear MDC/MDIO warning message bnx2x: Fix BCM57711+BCM84823 link issue bnx2x: Clear BCM84833 LED after fan failure bnx2x: Fix BCM84833 PHY FW version presentation bnx2x: Fix link issue for BCM8727 boards. ...

git://git.linaro.org/people/mszyprowski/linux-dma-mapping Pull DMA mapping branch from Marek Szyprowski: "Short summary for the whole series: A few limitations have been identified in the current dma-mapping design and its implementations for various architectures. There exist more than one function for allocating and freeing the buffers: currently these 3 are used dma_{alloc, free}_coherent, dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent. For most of the systems these calls are almost equivalent and can be interchanged. For others, especially the truly non-coherent ones (like ARM), the difference can be easily noticed in overall driver performance. Sadly not all architectures provide implementations for all of them, so the drivers might need to be adapted and cannot be easily shared between different architectures. The provided patches unify all these functions and hide the differences under the already existing dma attributes concept. The thread with more references is available here: http://www.spinics.net/lists/linux-sh/msg09777.html These patches are also a prerequisite for unifying DMA-mapping implementation on ARM architecture with the common one provided by dma_map_ops structure and extending it with IOMMU support. More information is available in the following thread: http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819 More works on dma-mapping framework are planned, especially in the area of buffer sharing and managing the shared mappings (together with the recently introduced dma_buf interface: commit d15bd7ee445d "dma-buf: Introduce dma buffer sharing mechanism"). The patches in the current set introduce a new alloc/free methods (with support for memory attributes) in dma_map_ops structure, which will later replace dma_alloc_coherent and dma_alloc_writecombine functions." People finally started piping up with support for merging this, so I'm merging it as the last of the pending stuff from the merge window. Looks like pohmelfs is going to wait for 3.5 and more external support for merging. * 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: common: DMA-mapping: add NON-CONSISTENT attribute common: DMA-mapping: add WRITE_COMBINE attribute common: dma-mapping: introduce mmap method common: dma-mapping: remove old alloc_coherent and free_coherent methods Hexagon: adapt for dma_map_ops changes Unicore32: adapt for dma_map_ops changes Microblaze: adapt for dma_map_ops changes SH: adapt for dma_map_ops changes Alpha: adapt for dma_map_ops changes SPARC: adapt for dma_map_ops changes PowerPC: adapt for dma_map_ops changes MIPS: adapt for dma_map_ops changes X86 & IA64: adapt for dma_map_ops changes common: dma-mapping: introduce generic alloc() and free() methods
