Pull workqueue changes from Tejun Heo: "There are three major changes. - WQ_HIGHPRI has been reimplemented so that high priority work items are served by worker threads with -20 nice value from dedicated highpri worker pools. - CPU hotplug support has been reimplemented such that idle workers are kept across CPU hotplug events. This makes CPU hotplug cheaper (for PM) and makes the code simpler. - flush_kthread_work() has been reimplemented so that a work item can be freed while executing.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "The most important part of these updates is the IOMMU groups code enhancement written by Alex Williamson. It abstracts the problem that a given hardware IOMMU can't isolate any given device from any other device (e.g. 32 bit PCI devices can't usually be isolated). Devices that can't be isolated are grouped together. This code is required for the upcoming VFIO framework. Another IOMMU-API change written by me is the introduction of domain attributes. This makes it easier to handle GART-like IOMMUs with the IOMMU-API because now the start-address and the size of the domain address space can be queried. Besides that there are a few cleanups and fixes for the NVidia Tegra IOMMU drivers and the reworked init-code for the AMD IOMMU. The latter is from my patch-set to support interrupt remapping. The rest of this patch-set requires x86 changes which are not mergabe yet. So full support for interrupt remapping with AMD IOMMUs will come in a future merge window." * tag 'iommu-updates-v3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (33 commits) iommu/amd: Fix hotplug with iommu=pt iommu/amd: Add missing spin_lock initialization iommu/amd: Convert iommu initialization to state machine iommu/amd: Introduce amd_iommu_init_dma routine iommu/amd: Move unmap_flush message to amd_iommu_init_dma_ops() iommu/amd: Split enable_iommus() routine iommu/amd: Introduce early_amd_iommu_init routine iommu/amd: Move informational prinks out of iommu_enable iommu/amd: Split out PCI related parts of IOMMU initialization iommu/amd: Use acpi_get_table instead of acpi_table_parse iommu/amd: Fix sparse warnings iommu/tegra: Don't call alloc_pdir with as->lock iommu/tegra: smmu: Fix unsleepable memory allocation at alloc_pdir() iommu/tegra: smmu: Remove unnecessary sanity check at alloc_pdir() iommu/exynos: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/tegra: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/msm: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/omap: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/vt-d: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/amd: Implement DOMAIN_ATTR_GEOMETRY attribute ...

Pull networking changes from David S Miller: 1) Remove the ipv4 routing cache. Now lookups go directly into the FIB trie and use prebuilt routes cached there. No more garbage collection, no more rDOS attacks on the routing cache. Instead we now get predictable and consistent performance, no matter what the pattern of traffic we service. This has been almost 2 years in the making. Special thanks to Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who have helped along the way. I'm sure that with a change of this magnitude there will be some kind of fallout, but such things ought the be simple to fix at this point. Luckily I'm not European so I'll be around all of August to fix things :-) The major stages of this work here are each fronted by a forced merge commit whose commit message contains a top-level description of the motivations and implementation issues. 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on input. 3) TCP SYN/ACK performance tweaks from Eric Dumazet. 4) Add namespace support for netfilter L4 conntrack helpers, from Gao Feng. 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from Yuval Mintz. 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet. 7) Support for connection tracker helpers in userspace, from Pablo Neira Ayuso. 8) Allow userspace driven TX load balancing functions in TEAM driver, from Jiri Pirko. 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with embedded gotos. 10) TCP Small Queues, essentially minimize the amount of TCP data queued up in the packet scheduler layer.

2012-07-24i2c: Add SCCB supportLaurent Pinchart
SCCB is a serial communication bus developed by Omnivision. Its 2-wire mode is very similar to SMBus byte data transactions, but requires the controller to ignore the ACK bit and to insert a stop condition after each message. Add a device SCCB flag and a message stop flag to be passed to controller drivers.

2012-07-23ipv4: Prepare for change of rt->rt_iif encoding.David S. Miller
Use inet_iif() consistently, and for TCP record the input interface of cached RX dst in inet sock. rt->rt_iif is going to be encoded differently, so that we can legitimately cache input routes in the FIB info more aggressively. When the input interface is "use SKB device index" the rt->rt_iif will be set to zero. This forces us to move the TCP RX dst cache installation into the ipv4 specific code, and as well it should since doing the route caching for ipv6 is pointless at the moment since it is not inspected in the ipv6 input paths yet. Also, remove the unlikely on dst->obsolete, all ipv4 dsts have obsolete set to a non-zero value to force invocation of the check callback. Signed-off-by: David S. Miller <davem@davemloft.net>

This is similar to the Xilinx zynq platform we already support. The code is particularly clean, which is helped by the fact that the hardware doesn't do much besides the parts that are expected to get added in the FPGA. - The OMAP subarchitecture gains support for the latest generation, the OMAP5 based on the new Cortex-A15 core.

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull the big VFS changes from Al Viro: "This one is *big* and changes quite a few things around VFS. What's in there: - the first of two really major architecture changes - death to open intents. The former is finally there; it was very long in making, but with Miklos getting through really hard and messy final push in fs/namei.c, we finally have it. Unlike his variant, this one doesn't introduce struct opendata; what we have instead is ->atomic_open() taking preallocated struct file * and passing everything via its fields. Instead of returning struct file *, it returns -E... on error, 0 on success and 1 in "deal with it yourself" case (e.g. symlink found on server, etc.). See comments before fs/namei.c:atomic_open(). That made a lot of goodies finally possible and quite a few are in that pile: ->lookup(), ->d_revalidate() and ->create() do not get struct nameidata * anymore; ->lookup() and ->d_revalidate() get lookup flags instead, ->create() gets "do we want it exclusive" flag. With the introduction of new helper (kern_path_locked()) we are rid of all struct nameidata instances outside of fs/namei.c; it's still visible in namei.h, but not for long. Come the next cycle, declaration will move either to fs/internal.h or to fs/namei.c itself. [me, miklos, hch] - The second major change: behaviour of final fput(). Now we have __fput() done without any locks held by caller *and* not from deep in call stack. That obviously lifts a lot of constraints on the locking in there. Moreover, it's legal now to call fput() from atomic contexts (which has immediately simplified life for aio.c). We also don't need anti-recursion logics in __scm_destroy() anymore. There is a price, though - the damn thing has become partially asynchronous. For fput() from normal process we are guaranteed that pending __fput() will be done before the caller returns to userland, exits or gets stopped for ptrace. For kernel threads and atomic contexts it's done via schedule_work(), so theoretically we might need a way to make sure it's finished; so far only one such place had been found, but there might be more. There's flush_delayed_fput() (do all pending __fput()) and there's __fput_sync() (fput() analog doing __fput() immediately). I hope we won't need them often; see warnings in fs/file_table.c for details. [me, based on task_work series from Oleg merged last cycle] - sync series from Jan - large part of "death to sync_supers()" work from Artem; the only bits missing here are exofs and ext4 ones. As far as I understand, those are going via the exofs and ext4 trees resp.; once they are in, we can put ->write_super() to the rest, along with the thread calling it. - preparatory bits from unionmount series (from dhowells). - assorted cleanups and fixes all over the place, as usual. This is not the last pile for this cycle; there's at least jlayton's ESTALE work and fsfreeze series (the latter - in dire need of fixes, so I'm not sure it'll make the cut this cycle). I'll probably throw symlink/hardlink restrictions stuff from Kees into the next pile, too.

2012-07-23tcp: dont drop MTU reduction indicationsEric Dumazet
ICMP messages generated in output path if frame length is bigger than mtu are actually lost because socket is owned by user (doing the xmit) One example is the ipgre_tunnel_xmit() calling icmp_send(skb, ICMP_DEST_UNREACH, ICMP_FRAG_NEEDED, htonl(mtu)); We had a similar case fixed in commit a34a101e1e6 (ipv6: disable GSO on sockets hitting dst_allfrag). Problem of such fix is that it relied on retransmit timers, so short tcp sessions paid a too big latency increase price. This patch uses the tcp_release_cb() infrastructure so that MTU reduction messages (ICMP messages) are not lost, and no extra delay is added in TCP transmits.

2012-07-23Merge branch 'kill_rtcache'David S. Miller
The ipv4 routing cache is non-deterministic, performance wise, and is subject to reasonably easy to launch denial of service attacks. The routing cache works great for well behaved traffic, and the world was a much friendlier place when the tradeoffs that led to the routing cache's design were considered. What it boils down to is that the performance of the routing cache is a product of the traffic patterns seen by a system rather than being a product of the contents of the routing tables. The former of which is controllable by external entitites. Even for "well behaved" legitimate traffic, high volume sites can see hit rates in the routing cache of only ~%10. The general flow of this patch series is that first the routing cache is removed. We build a completely new rtable entry every lookup request. Next we make some simplifications due to the fact that removing the routing cache causes several members of struct rtable to become no longer necessary. Then we need to make some amends such that we can legally cache pre-constructed routes in the FIB nexthops. Firstly, we need to invalidate routes which are hit with nexthop exceptions. Secondly we have to change the semantics of rt->rt_gateway such that zero means that the destination is on-link and non-zero otherwise. Now that the preparations are ready, we start caching precomputed routes in the FIB nexthops. Output and input routes need different kinds of care when determining if we can legally do such caching or not. The details are in the commit log messages for those changes. The patch series then winds down with some more struct rtable simplifications and other tidy ups that remove unnecessary overhead. On a SPARC-T3 output route lookups are ~876 cycles. Input route lookups are ~1169 cycles with rpfilter disabled, and about ~1468 cycles with rpfilter enabled. These measurements were taken with the kbench_mod test module in the net_test_tools GIT tree: git://git.kernel.org/pub/scm/linux/kernel/git/davem/net_test_tools.git That GIT tree also includes a udpflood tester tool and stresses route lookups on packet output. For example, on the same SPARC-T3 system we can run: time ./udpflood -l 10000000 10.2.2.11 with routing cache: real 1m21.955s user 0m6.530s sys 1m15.390s without routing cache: real 1m31.678s user 0m6.520s sys 1m25.140s Performance undoubtedly can easily be improved further. For example fib_table_lookup() performs a lot of excessive computations with all the masking and shifting, some of it conditionalized to deal with edge cases. Also, Eric's no-ref optimization for input route lookups can be re-instated for the FIB nexthop caching code path. I would be really pleased if someone would work on that. In fact anyone suitable motivated can just fire up perf on the loading of the test net_test_tools benchmark kernel module. I spend much of my time going: bash# perf record insmod ./kbench_mod.ko dst=172.30.42.22 src=74.128.0.1 iif=2 bash# perf report Thanks to helpful feedback from Joe Perches, Eric Dumazet, Ben Hutchings, and others.

2012-07-22vfs: allow custom EOF in generic_file_llseek codeEric Sandeen
For ext3/4 htree directories, using the vfs llseek function with SEEK_END goes to i_size like for any other file, but in reality we want the maximum possible hash value. Recent changes in ext4 have cut & pasted generic_file_llseek() back into fs/ext4/dir.c, but replicating this core code seems like a bad idea, especially since the copy has already diverged from the vfs. This patch updates generic_file_llseek_size to accept both a custom maximum offset, and a custom EOF position. With this in place, ext4_dir_llseek can pass in the appropriate maximum hash position for both maxsize and eof, and get what it wants. As far as I know, this does not fix any bugs - nfs in the kernel doesn't use SEEK_END, and I don't know of any user who does. But some ext4 folks seem keen on doing the right thing here, and I can't really argue.

2012-07-22switch fput to task_work_addAl Viro
... and schedule_work() for interrupt/kernel_thread callers (and yes, now it *is* OK to call from interrupt). We are guaranteed that __fput() will be done before we return to userland (or exit). Note that for fput() from a kernel thread we get an async behaviour; it's almost always OK, but sometimes you might need to have __fput() completed before you do anything else. There are two mechanisms for that - a general barrier (flush_delayed_fput()) and explicit __fput_sync(). Both should be used with care (as was the case for fput() from kernel threads all along). See comments in fs/file_table.c for details. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
