We do have two small incrementals queued up, but I wanted to get this bunch out the door before I hop on an airplane.

It closes a long standing performance issue that was built in to the disk format. Mark Fasheh's offline dedup work is also here. In this case offline means the FS is mounted and active, but the dedup work is not done inline during file IO. This is a building block where utilities are able to ask the FS to dedup a series of extents. The kernel takes care of verifying the data involved really is the same.

fs: bump inode and dentry counters to long
This series reworks our current object cache shrinking infrastructure in two main ways: * Noticing that a lot of users copy and paste their own version of LRU lists for objects, we put some effort in providing a generic version. It is modeled after the filesystem users: dentries, inodes, and xfs (for various tasks), but we expect that other users could benefit in the near future with little or no modification. Let us know if you have any issues. * The underlying list_lru being proposed automatically and transparently keeps the elements in per-node lists, and is able to manipulate the node lists individually. Given this infrastructure, we are able to modify the up-to-now hammer called shrink_slab to proceed with node-reclaim instead of always searching memory from all over like it has been doing. Per-node lru lists are also expected to lead to less contention in the lru locks on multi-node scans, since we are now no longer fighting for a global lock. The locks usually disappear from the profilers with this change. Although we have no official benchmarks for this version - be our guest to independently evaluate this - earlier versions of this series were performance tested (details at http://permalink.gmane.org/gmane.linux.kernel.mm/100537) yielding no visible performance regressions while yielding a better qualitative behavior in NUMA machines. With this infrastructure in place, we can use the list_lru entry point to provide memcg isolation and per-memcg targeted reclaim. Historically, those two pieces of work have been posted together. This version presents only the infrastructure work, deferring the memcg work for a later time, so we can focus on getting this part tested. You can see more about the history of such work at http://lwn.net/Articles/552769/ Dave Chinner (18): dcache: convert dentry_stat.nr_unused to per-cpu counters dentry: move to per-sb LRU locks dcache: remove dentries from LRU before putting on dispose list mm: new shrinker API shrinker: convert superblock shrinkers to new API list: add a new LRU list type inode: convert inode lru list to generic lru list code. dcache: convert to use new lru list infrastructure list_lru: per-node list infrastructure shrinker: add node awareness fs: convert inode and dentry shrinking to be node aware xfs: convert buftarg LRU to generic code xfs: rework buffer dispose list tracking xfs: convert dquot cache lru to list_lru fs: convert fs shrinkers to new scan/count API drivers: convert shrinkers to new count/scan API shrinker: convert remaining shrinkers to count/scan API shrinker: Kill old ->shrink API. Glauber Costa (7): fs: bump inode and dentry counters to long super: fix calculation of shrinkable objects for small numbers list_lru: per-node API vmscan: per-node deferred work i915: bail out earlier when shrinker cannot acquire mutex hugepage: convert huge zero page shrinker to new shrinker API list_lru: dynamically adjust node arrays This patch: There are situations in very large machines in which we can have a large quantity of dirty inodes, unused dentries, etc. This is particularly true when umounting a filesystem, where eventually since every live object will eventually be discarded. Dave Chinner reported a problem with this while experimenting with the shrinker revamp patchset. So we believe it is time for a change. This patch just moves int to longs. Machines where it matters should have a big long anyway.

VFIO updates include safer default file flags for VFIO device fds,
an external user interface exported to allow other modules to hold references to VFIO groups, a fix to test for extended config space on PCIe and PCI-x, and new hot reset interfaces for PCI devices which allows the user to do PCI bus/slot resets when all of the devices affected by the reset are owned by the user. For this last feature, the PCI bus reset interface, I depend on changes already merged from Bjorn's PCI pull request. I therefore merged my tree up to commit |

Input: evdev - add EVIOCREVOKE ioctl
If we have multiple sessions on a system, we normally don't want background sessions to read input events. Otherwise, it could capture passwords and more entered by the user on the foreground session. This is a real world problem as the recent XMir development showed: http://mjg59.dreamwidth.org/27327.html We currently rely on sessions to release input devices when being deactivated. This relies on trust across sessions. But that's not given on usual systems. We therefore need a way to control which processes have access to input devices. With VTs the kernel simply routed them through the active /dev/ttyX. This is not possible with evdev devices, though. Moreover, we want to avoid routing input-devices through some dispatcher-daemon in userspace (which would add some latency). This patch introduces EVIOCREVOKE. If called on an evdev fd, this revokes device-access irrecoverably for that *single* open-file. Hence, once you call EVIOCREVOKE on any dup()ed fd, all fds for that open-file will be rather useless now (but still valid compared to close()!). This allows us to pass fds directly to session-processes from a trusted source. The source keeps a dup()ed fd and revokes access once the session-process is no longer active. Compared to the EVIOCMUTE proposal, we can avoid the CAP_SYS_ADMIN restriction now as there is no way to revive the fd again. Hence, a user is free to call EVIOCREVOKE themself to kill the fd. Additionally, this ioctl allows multi-layer access-control (again compared to EVIOCMUTE which was limited to one layer via CAP_SYS_ADMIN). A middle layer can simply request a new open-file from the layer above and pass it to the layer below. Now each layer can call EVIOCREVOKE on the fds to revoke access for all layers below, at the expense of one fd per layer. There's already ongoing experimental user-space work which demonstrates how it can be used: http://lists.freedesktop.org/archives/systemd-devel/2013-August/012897.html Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> |

dm: add statistics support
Support the collection of I/O statistics on user-defined regions of a DM device. If no regions are defined no statistics are collected so there isn't any performance impact. Only bio-based DM devices are currently supported. Each user-defined region specifies a starting sector, length and step. Individual statistics will be collected for each step-sized area within the range specified. The I/O statistics counters for each step-sized area of a region are in the same format as /sys/block/*/stat or /proc/diskstats but extra counters (12 and 13) are provided: total time spent reading and writing in milliseconds. All these counters may be accessed by sending the @stats_print message to the appropriate DM device via dmsetup. The creation of DM statistics will allocate memory via kmalloc or fallback to using vmalloc space. At most, 1/4 of the overall system memory may be allocated by DM statistics. The admin can see how much memory is used by reading /sys/module/dm_mod/parameters/stats_current_allocated_bytes See Documentation/device-mapper/statistics.txt for more details.

New features for 3.12:
* Added aggressive extent caching using the extent status tree.

vfio-pci: PCI hot reset interface
The current VFIO_DEVICE_RESET interface only maps to PCI use cases where we can isolate the reset to the individual PCI function. This means the device must support FLR (PCIe or AF), PM reset on D3hot->D0 transition, device specific reset, or be a singleton device on a bus for a secondary bus reset. FLR does not have widespread support, PM reset is not very reliable, and bus topology is dictated by the system and device design. We need to provide a means for a user to induce a bus reset in cases where the existing mechanisms are not available or not reliable. This device specific extension to VFIO provides the user with this ability. Two new ioctls are introduced: - VFIO_DEVICE_PCI_GET_HOT_RESET_INFO - VFIO_DEVICE_PCI_HOT_RESET The first provides the user with information about the extent of devices affected by a hot reset. This is essentially a list of devices and the IOMMU groups they belong to. The user may then initiate a hot reset by calling the second ioctl. We must be careful that the user has ownership of all the affected devices found via the first ioctl, so the second ioctl takes a list of file descriptors for the VFIO groups affected by the reset. Each group must have IOMMU protection established for the ioctl to succeed. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> |

net: sync some IP headers with glibc
Solution: ========= - Synchronize linux's `include/uapi/linux/in6.h' with glibc's `inet/netinet/in.h'. - Synchronize glibc's `inet/netinet/in.h with linux's `include/uapi/linux/in6.h'. - Allow including the headers in either other. - First header included defines the structures and macros. Details: ======== The kernel promises not to break the UAPI ABI so I don't see why we can't just have the two userspace headers coordinate? If you include the kernel headers first you get those, and if you include the glibc headers first you get those, and the following patch arranges a coordination and synchronization between the two. Let's handle `include/uapi/linux/in6.h' from linux, and `inet/netinet/in.h' from glibc and ensure they compile in any order and preserve the required ABI. These two patches pass the following compile tests: cat >> test1.c <<EOF int main (void) { return 0; } EOF gcc -c test1.c cat >> test2.c <<EOF int main (void) { return 0; } EOF gcc -c test2.c One wrinkle is that the kernel has a different name for one of the members in ipv6_mreq. In the kernel patch we create a macro to cover the uses of the old name, and while that's not entirely clean it's one of the best solutions (aside from an anonymous union which has other issues). I've reviewed the code and it looks to me like the ABI is assured and everything matches on both sides. Notes: - You want netinet/in.h to include bits/in.h as early as possible, but it needs in_addr so define in_addr early. - You want bits/in.h included as early as possible so you can use the linux specific code to define __USE_KERNEL_DEFS based on the _UAPI_* macro definition and use those to cull in.h. - glibc was missing IPPROTO_MH, added here. Compile tested and inspected.

Input: introduce BTN/ABS bits for drums and guitars
There are a bunch of guitar and drums devices out there that all report similar data. To avoid reporting this as BTN_MISC or ABS_MISC, we allocate some proper namespace for them. Note that most of these devices are toys and we cannot report any sophisticated physics via this API. I did some google-images research and tried to provide definitions that work with all common devices. That's why I went with 4 toms, 4 cymbals, one bass, one hi-hat. I haven't seen other drums and I doubt that we need any additions to that. Anyway, the naming-scheme is intentionally done in an extensible way. For guitars, we support 5 frets (normally aligned vertically, compared to the real horizontal layouts), a single strum-bar with up/down directions, an optional fret-board and a whammy-bar. Most of the devices provide pressure values so I went with ABS_* bits. If we ever support devices which only provide digital input, we have to decide whether to emulate pressure data or add additional BTN_* bits. If someone is not familiar with these devices, here are two pictures which provide almost all introduced interfaces (or try the given keywords with a google-image search): Guitar: ("guitar hero world tour guitar") http://images1.wikia.nocookie.net/__cb20120911023442/applezone/es/images/f/f9/Wii_Guitar.jpg Drums: ("guitar hero drums") http://oyster.ignimgs.com/franchises/images/03/55/35526_band-hero-drum-set-hands-on-20090929040735768.jpg Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> |

ICMPv6: treat dest unreachable codes 5 and 6 as EACCES, not EPROTO
RFC 4443 has defined two additional codes for ICMPv6 type 1 (destination unreachable) messages: 5 - Source address failed ingress/egress policy 6 - Reject route to destination Now they are treated as protocol error and icmpv6_err_convert() converts them to EPROTO. RFC 4443 says: "Codes 5 and 6 are more informative subsets of code 1."

John W. Linville says: ==================== Please accept this batch of updates intended for the 3.12 stream. For the mac80211 bits, Johannes says this: "This time I have various improvements all over the place: IBSS, mesh, testmode, AP client powersave handling, one of the rare rfkill patches and some code cleanup." Also for mac80211: "And I also have some more changes for -next, just a few small fixes and improvements, nothing really stands out." And for iwlwifi: "This time I have some powersave work (notably uAPSD support), CQM offloads, support for a new firmware API and various code cleanups." Regarding the Bluetooth bits, Gustavo says: "Patches to 3.12, here we have: * implementation of a proper tty_port for RFCOMM devices, this fixes some issues people were seeing lately in the kernel. * Add voice_setting option for SCO, it is used for SCO Codec selection * bugfixes, small improvements and clean ups" For the NFC bits, Samuel says: "With this one we have: - A few pn533 improvements and minor fixes. Testing our pn533 driver against Google's NCI stack triggered a few issues that we fixed now. We also added Tx fragmentation support to this driver. - More NFC secure element handling. We added a GET_SE netlink command for getting all the discovered secure elements, and we defined 2 additional secure element netlink event (transaction and connectivity). We also fixed a couple of typos and copy-paste bugs from the secure element handling code. - Firmware download support for the pn544 driver. This chipset can enter a special mode where it's waiting for firmware blobs to replace the already flashed one. We now support that mode." With repect to the ath tree, Kalle says: "New features in ath10k are rx/tx checsumming in hw and survey scan implemented by Michal. Also he made fixes to different areas of the driver, most notable being fixing the case when using two streams and reducing the number of interface combinations to avoid firmware crashes. Bartosz did a clean related to how we handle SoC power save in PCI layer. For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent crashes." I also pulled the wireless tree into wireless-next to support a request from Johannes. On top of all that, there are the usual sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k, and rt2x00 drivers all get some attention, as does the bcma bus and a few other random bits here and there. ==================== Signed-off-by: David S.

TTY/Serial driver patches for 3.12-rc1
Here's the big tty/serial driver pull request for 3.12-rc1. Lots of n_tty reworks to resolve some very long-standing issues, removing the 3-4 different locks that were taken for every character. This code has been beaten on for a long time in linux-next with no reported regressions. Other than that, a range of serial and tty driver updates and revisions. Full details in the shortlog.

perf: Add a dummy software event to keep tracking
When an event is disabled the "tracking" events selected by the 'mmap', 'comm' and 'task' bits of struct perf_event_attr, are also disabled. However, the information those events provide is necessary to resolve symbols for when the main event is re-enabled. The "tracking" events can be kept enabled by putting them on another event, but that requires an event that otherwise does nothing. A new software event PERF_COUNT_SW_DUMMY is added for that purpose.
