git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull vfs update from Al Viro: - big one - consolidation of descriptor-related logics; almost all of that is moved to fs/file.c (BTW, I'm seriously tempted to rename the result to fd.c. As it is, we have a situation when file_table.c is about handling of struct file and file.c is about handling of descriptor tables; the reasons are historical - file_table.c used to be about a static array of struct file we used to have way back). A lot of stray ends got cleaned up and converted to saner primitives, disgusting mess in android/binder.c is still disgusting, but at least doesn't poke so much in descriptor table guts anymore. A bunch of relatively minor races got fixed in process, plus an ext4 struct file leak. - related thing - fget_light() partially unuglified; see fdget() in there (and yes, it generates the code as good as we used to have). - also related - bits of Cyrill's procfs stuff that got entangled into that work; _not_ all of it, just the initial move to fs/proc/fd.c and switch of fdinfo to seq_file. - Alex's fs/coredump.c spiltoff - the same story, had been easier to take that commit than mess with conflicts. The rest is a separate pile, this was just a mechanical code movement. - a few misc patches all over the place. Not all for this cycle, there'll be more (and quite a few currently sit in akpm's tree)." Fix up trivial conflicts in the android binder driver, and some fairly simple conflicts due to two different changes to the sock_alloc_file() interface ("take descriptor handling from sock_alloc_file() to callers" vs "net: Providing protocol type via system.sockprotoname xattr of /proc/PID/fd entries" adding a dentry name to the socket) * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (72 commits) MAX_LFS_FILESIZE should be a loff_t compat: fs: Generic compat_sys_sendfile implementation fs: push rcu_barrier() from deactivate_locked_super() to filesystems btrfs: reada_extent doesn't need kref for refcount coredump: move core dump functionality into its own file coredump: prevent double-free on an error path in core dumper usb/gadget: fix misannotations fcntl: fix misannotations ceph: don't abuse d_delete() on failure exits hypfs: ->d_parent is never NULL or negative vfs: delete surplus inode NULL check switch simple cases of fget_light to fdget new helpers: fdget()/fdput() switch o2hb_region_dev_write() to fget_light() proc_map_files_readdir(): don't bother with grabbing files make get_file() return its argument vhost_set_vring(): turn pollstart/pollstop into bool switch prctl_set_mm_exe_file() to fget_light() switch xfs_find_handle() to fget_light() switch xfs_swapext() to fget_light() ...

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull user namespace changes from Eric Biederman: "This is a mostly modest set of changes to enable basic user namespace support. This allows the code to code to compile with user namespaces enabled and removes the assumption there is only the initial user namespace. Everything is converted except for the most complex of the filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs, nfs, ocfs2 and xfs as those patches need a bit more review. The strategy is to push kuid_t and kgid_t values are far down into subsystems and filesystems as reasonable. Leaving the make_kuid and from_kuid operations to happen at the edge of userspace, as the values come off the disk, and as the values come in from the network. Letting compile type incompatible compile errors (present when user namespaces are enabled) guide me to find the issues. The most tricky areas have been the places where we had an implicit union of uid and gid values and were storing them in an unsigned int. Those places were converted into explicit unions. I made certain to handle those places with simple trivial patches. Out of that work I discovered we have generic interfaces for storing quota by projid. I had never heard of the project identifiers before. Adding full user namespace support for project identifiers accounts for most of the code size growth in my git tree. Ultimately there will be work to relax privlige checks from "capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing root in a user names to do those things that today we only forbid to non-root users because it will confuse suid root applications. While I was pushing kuid_t and kgid_t changes deep into the audit code I made a few other cleanups. I capitalized on the fact we process netlink messages in the context of the message sender. I removed usage of NETLINK_CRED, and started directly using current->tty. Some of these patches have also made it into maintainer trees, with no problems from identical code from different trees showing up in linux-next. After reading through all of this code I feel like I might be able to win a game of kernel trivial pursuit."

2012-10-02Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wqLinus Torvalds5-5/+5
Pull workqueue changes from Tejun Heo: "This is workqueue updates for v3.7-rc1. A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc cleanups, part 2 from Olof Johansson: "A shorter cleanup branch submitted separately due to dependencies with some of the previous topics. Major thing here is that the Broadcom bcmring platform is removed. It's an SoC that's used on some stationary VoIP platforms, and is in desperate need of some cleanup. Broadcom came back and suggested that we just deprecate the platform for now, since they aren't going to spend the resources needed on cleaning it up, and there are no users of the platform directly from mainline."

This is a series from Rob Herring that restructures how all pci devices allocate I/O space, and it's part of the work to allow multiplatform kernels. - A number of cleanup series for OMAP, moving and removing some headers, sparse irq rework and in general preparation for multiplatform. - Final removal of all non-DT boards for Tegra, it is now device-tree-only! - Removal of a stale platform, nxp4008. It's an old mobile chipset that is no longer in use, and was very likely never really used with a mainline kernel. We have not been able to find anyone interested in keeping it around in the kernel. - Removal of the legacy dmaengine driver on tegra + A handful of other things that I haven't described above."

2012-09-27USB: Fix race condition when removing host controllersAlan Stern2-5/+3
This patch (as1607) fixes a race that can occur if a USB host controller is removed while a process is reading the /sys/kernel/debug/usb/devices file. The usb_device_read() routine uses the bus->root_hub pointer to determine whether or not the root hub is registered. The is not a valid test, because the pointer is set before the root hub gets registered and remains set even after the root hub is unregistered and deallocated. As a result, usb_device_read() or usb_device_dump() can access freed memory, causing an oops. The patch changes the test to use the hcd->rh_registered flag, which does get set and cleared at the appropriate times. It also makes sure to hold the usb_bus_list_lock mutex while setting the flag, so that usb_device_read() will become aware of new root hubs as soon as they are registered.

2012-09-26USB: Fix race condition when removing host controllersAlan Stern2-5/+3
This patch (as1607) fixes a race that can occur if a USB host controller is removed while a process is reading the /sys/kernel/debug/usb/devices file. The usb_device_read() routine uses the bus->root_hub pointer to determine whether or not the root hub is registered. The is not a valid test, because the pointer is set before the root hub gets registered and remains set even after the root hub is unregistered and deallocated. As a result, usb_device_read() or usb_device_dump() can access freed memory, causing an oops. The patch changes the test to use the hcd->rh_registered flag, which does get set and cleared at the appropriate times. It also makes sure to hold the usb_bus_list_lock mutex while setting the flag, so that usb_device_read() will become aware of new root hubs as soon as they are registered.

2012-09-25xhci: Intel Panther Point BEI quirk.Sarah Sharp3-1/+5
When a device with an isochronous endpoint is behind a hub plugged into the Intel Panther Point xHCI host controller, and the driver submits multiple frames per URB, the xHCI driver will set the Block Event Interrupt (BEI) flag on all but the last TD for the URB. This causes the host controller to place an event on the event ring, but not send an interrupt. When the last TD for the URB completes, BEI is cleared, and we get an interrupt for the whole URB. However, under a Panther Point xHCI host controller, if the parent hub is unplugged when one or more events from transfers with BEI set are on the event ring, a port status change event is placed on the event ring, but no interrupt is generated. This means URBs stop completing, and the USB device disconnect is not noticed. Something like a USB headset will cause mplayer to hang when the device is disconnected. If another transfer is sent (such as running `sudo lsusb -v`), the next transfer event seems to "unstick" the event ring, the xHCI driver gets an interrupt, and the disconnect is reported to the USB core. The fix is not to use the BEI flag under the Panther Point xHCI host. This will impact power consumption and system responsiveness, because the xHCI driver will receive an interrupt for every frame in all isochronous URBs instead of once per URB. Intel chipset developers confirm that this bug will be hit if the BEI flag is used on any endpoint, not just ones that are behind a hub. This patch should be backported to kernels as old as 3.0, that contain the commit 69e848c2090aebba5698a1620604c7dccb448684 "Intel xhci: Support EHCI/xHCI port switching."

2012-09-21USB: EHCI: convert warning messages to debug-levelAlan Stern1-2/+4
This patch (as1606) converts two warning messages in the ehci-hcd driver to debug messages, and adds a little extra information to each. The log messages occur when an EHCI controller takes too long (more than 20 ms) to turn its async or periodic schedule on or off. If this happens at all, it's liable to happen quite often and there's no point spamming the system log with these warnings. Furthermore, there's nothing much we can do about it when the problem happens.

git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/cleanup2 ARM: tegra: second round of cleanups This branch mainly removes dead code following the removal of all board files. The removals depend on various changes in other branches, so they are all merged together and form the basis of this branch, as enumerated below. Finally, there are no remaining users of pinconf-tegra.h outside the pinctrl subsystem, so that header is incorporated into an existing file there. This reduces the number of headers in mach-tegra/include, and so helps move towards single zImage.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into next/cleanup2 usb: xceiv: patches for v3.7 merge window nop xceiv got its own header to avoid polluting otg.h. It has also learned to work as USB2 and USB3 phys so we can use it on USB3 controllers. Together with those two changes to nop xceiv, we're adding basic PHY support to dwc3 driver, this is to allow platforms which actually have a SW-controllable PHY talk to them through dwc3 driver. We're adding a new phy driver for the OMAP architecture. This driver is for the PHY found in OMAP4 SoCs, and a new phy driver for the marvell architecture. An extra phy driver - for Tegra SoCs - is now moving from arch/arm/mach-tegra* to drivers/usb/phy. Also here, there's the creation of <linux/usb/phy.h> which should be used from now on for PHY drivers, even those which don't support OTG. * tag 'xceiv-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb: usb: otg: mxs-phy: Fix mx23 operation usb: dwc3: add basic PHY support usb: dwc3: exynos: add nop transceiver support usb: dwc3: omap: add nop transceiver support usb: dwc3: pci: add nop transceiver support usb: otg: move the dereference below the NULL test arm: omap: phy: remove unused functions from omap-phy-internal.c usb: twl4030: Add device tree support for twl4030 usb usb: twl6030: Add dt support for twl6030 usb usb: otg: make twl6030_usb as a comparator driver to omap_usb2 usb: phy: add a new driver for omap usb2 phy usb: phy: fix build break usb: move phy driver from mach-tegra to drivers/usb usb: otg: Move phy interface to separate file. usb: phy: isp1301: Remove unused static array and define usb: phy: mv_u3d: Add usb phy driver for mv_u3d usb: otg: Remove the unneeded NULL check usb: xceiv: nop: let it work as USB2 and USB3 phy usb: xceiv: create nop-usb-xceiv.h and avoid pollution on otg.h Signed-off-by: Olof Johansson <olof@lixom.net>

This patch adds new functions to upload firmware to the controller. The drivers currently using ezusb are adapted to use these new functions. This also fixes a bug occuring during firmware loading in the whiteheat-driver: The driver iterates over an ihex-formatted firmware using ++ on a "const struct ihex_binrec*" which leads to faulty results, because ihex data is read as length. The function "ihex_next_binrec(record)" has so be used to work correctly Signed-off-by: René Bürgel <rene.buergel@sohard.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
