git:// Pull ktest confusion fix from Steven Rostedt: "With the v3.7-rc2 kernel, the network cards on my target boxes were not being brought up. I found that the modules for the network was not being installed. This was due to the config CONFIG_MODULES_USE_ELF_RELA that came before CONFIG_MODULES, and confused ktest in thinking that CONFIG_MODULES=y was not found. Ktest needs to test all configs and not just stop if something starts with CONFIG_MODULES." * tag 'ktest-v3.7-rc2' of git:// ktest: Fix ktest confusion with CONFIG_MODULES_USE_ELF_RELA

2012-10-28Lock splice_read and splice_write functionsMikulas Patocka1-2/+35
Functions generic_file_splice_read and generic_file_splice_write access the pagecache directly. For block devices these functions must be locked so that block size is not changed while they are in progress. This patch is an additional fix for commit b87570f5d349 ("Fix a crash when block device is read and block size is changed at the same time") that locked aio_read, aio_write and mmap against block size change.

2012-10-28percpu-rw-semaphores: use rcu_read_lock_schedMikulas Patocka1-4/+4
Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu. This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

2012-10-28percpu-rw-semaphores: use light/heavy barriersMikulas Patocka1-13/+7
This patch introduces new barrier pair light_mb() and heavy_mb() for percpu rw semaphores. This patch fixes a bug in percpu-rw-semaphores where a barrier was missing in percpu_up_write. This patch improves performance on the read path of percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in percpu_up_read. This patch changes it to a compiler barrier and removes the "#if defined(X86) ..." condition. From: Lai Jiangshan <> Signed-off-by: Mikulas Patocka <> Signed-off-by: Linus Torvalds <>

2012-10-26VFS: don't do protected {sym,hard}links by defaultLinus Torvalds1-2/+2
In commit 800179c9b8a1 ("This adds symlink and hardlink restrictions to the Linux VFS"), the new link protections were enabled by default, in the hope that no actual application would care, despite it being technically against legacy UNIX (and documented POSIX) behavior. However, it does turn out to break some applications. It's rare, and it's unfortunate, but it's unacceptable to break existing systems, so we'll have to default to legacy behavior. In particular, it has broken the way AFD distributes files, see along with some legacy scripts. Distributions can end up setting this at initrd time or in system scripts: if you have security problems due to link attacks during your early boot sequence, you have bigger problems than some kernel sysctl setting. Do: echo 1 > /proc/sys/fs/protected_symlinks echo 1 > /proc/sys/fs/protected_hardlinks to re-enable the link protections. Alternatively, we may at some point introduce a kernel config option that sets these kinds of "more secure but not traditional" behavioural options automatically.

2012-10-26net: usb: Fix memory leak on Tx data pathHemant Kumar1-0/+3
Driver anchors the tx urbs and defers the urb submission if a transmit request comes when the interface is suspended. Anchoring urb increments the urb reference count. These deferred urbs are later accessed by calling usb_get_from_anchor() for submission during interface resume. usb_get_from_anchor() unanchors the urb but urb reference count remains same. This causes the urb reference count to remain non-zero after usb_free_urb() gets called and urb never gets freed. Hence call usb_put_urb() after anchoring the urb to properly balance the reference count for these deferred urbs. Also, unanchor these deferred urbs during disconnect, to free them up.

2012-10-26net/mlx4_en: Fix double-release-range in tx-ringsJack Morgenstein1-1/+0
The QP range is reserved as a single block. However, when freeing the en resources, the tx-ring QPs are released both in mlx4_en_destroy_tx_ring (one at a time) and in mlx4_en_free_resources (as a block release). Fix by eliminating the one-at-a-time release in mlx4_en_destroy_tx_ring. Signed-off-by: Jack Morgenstein <> Signed-off-by: Or Gerlitz <> Signed-off-by: David S. Miller <>
2012-10-26bas_gigaset: fix pre_reset handlingTilman Schmidt1-3/+16
The delayed work function int_in_work() may call usb_reset_device() and thus, indirectly, the driver's pre_reset method. Trying to cancel the work synchronously in that situation would deadlock. Fix by avoiding cancel_work_sync() in the pre_reset method. If the reset was NOT initiated by int_in_work() this might cause int_in_work() to run after the post_reset method, with urb_int_in already resubmitted, so handle that case gracefully.

2012-10-26ktest: Fix ktest confusion with CONFIG_MODULES_USE_ELF_RELASteven Rostedt1-2/+4
In order to decide if ktest should bother installing modules on the target box, it checks if the config file has CONFIG_MODULES=y. But it also checks if the '=y' part exists. It only will install modules if the config exists and is set with '=y'. But as the regex that was used tests: /^CONFIG_MODULES(=y)?/ this will also match: CONFIG_MODULES_USE_ELF_RELA as the '=y' part was optional and it did not test the rest of the line. When this happens, ktest will stop checking the rest of the configs but it will also think that no modules are needed to be installed. What it should do is only jump out of the loop if it actually found a CONFIG_MODULES that is set to true. Otherwise, ktest wont install the necessary modules needed for proper booting of the test target. Signed-off-by: Steven Rostedt <>

2012-10-25Input: wacom - handle split-sensor devices with internal hubsJason Gerecke3-2/+35
Like our other pen-and-touch products, the Cintiq 24HD touch needs data to be shared between its two sensors to facilitate proximity-based palm rejection. Unlike other tablets that report sensor data through separate interfaces of the same USB device, the Cintiq 24HD touch has separate USB devices that are connected to an internal USB hub. This patch makes it possible to designate the USB VID/PID of the other device so that the two may share data. To ensure we don't accidentally link to a sensor from a physically separate device (if several have been plugged in), we limit the search to siblings (i.e., devices directly connected to the same hub).

2012-10-25Makefile: Documentation for external tool should be correctH. Peter Anvin1-4/+2
If one includes documentation for an external tool, it should be correct. This is not: 1. Overriding the input to rngd should typically be neither necessary nor desired. This is especially so since newer versions of rngd support a number of different *types* of sources. 2. The default kernel-exported device is called /dev/hwrng not /dev/hwrandom nor /dev/hw_random (both of which were used in the past; however, kernel and udev seem to have converged on /dev/hwrng.) Overall it is better if the documentation for rngd is kept with rngd rather than in a kernel Makefile. Signed-off-by: H.
