b01537b Linus Torvalds 29 November 2013, 17:27:19 UTC Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull vfs dentry reference count fix from Al Viro. This fixes a possible inode_permission NULL pointer dereference (and other problems) that were due to the root dentry count being decremented too much. In commit 48a066e72d97 ("RCU'd vfsmounts") the placement of clearing the LOOKUP_RCU bit changed, and we then returned failure of incrementing the lockref on the parent dentry with LOOKUP_RCU cleared. But that meant we needed to go through the same cleanup routines that the later failures did wrt LOOKUP_ROOT and nd->root. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fix bogus path_put() of nd->root after some unlazy_walk() failures 29 November 2013, 17:27:19 UTC

3676f9e Catalin Marinas 27 November 2013, 16:59:27 UTC arm64: Move PTE_PROT_NONE higher up PTE_PROT_NONE means that a pte is present but does not have any read/write attributes. However, setting the memory type like pgprot_writecombine() is allowed and such bits overlap with PTE_PROT_NONE. This causes mmap/munmap issues in drivers that change the vma->vm_pg_prot on PROT_NONE mappings. This patch reverts the PTE_FILE/PTE_PROT_NONE shift in commit 59911ca4325d (ARM64: mm: Move PTE_PROT_NONE bit) and moves PTE_PROT_NONE together with the other software bits.

d870b4a Al Viro 29 November 2013, 06:48:32 UTC fix bogus path_put() of nd->root after some unlazy_walk() failures Failure to grab reference to parent dentry should go through the same cleanup as nd->seq mismatch. As it is, we might end up with caller thinking it needs to path_put() nd->root, with obvious nasty results once we'd hit that bug enough times to drive the refcount of root dentry all the way to zero...

2ded3e5 Takashi Iwai 28 November 2013, 10:05:28 UTC ALSA: hda - Check leaf nodes to find aamix amps The current generic parser assumes blindly that the volume and mute amps are found in the aamix node itself. But on some codecs, typically Analog Devices ones, the aamix amps are separately implemented in each leaf node of the aamix node, and the current driver can't establish the correct amp controls. This is a regression compared with the previous static quirks. This patch extends the search for the amps to the leaf nodes for allowing the aamix controls again on such codecs. In this implementation, I didn't code to loop through the whole paths, since usually one depth should suffice, and we can't search too deeply, as it may result in the conflicting control assignments.

6d183de NeilBrown 27 November 2013, 23:55:27 UTC md/raid5: fix newly-broken locking in get_active_stripe. commit 566c09c53455d7c4f1 raid5: relieve lock contention in get_active_stripe() modified the locking in get_active_stripe() reducing the range protected by the (highly contended) device_lock. Unfortunately it reduced the range too much opening up some races. One race can occur if get_priority_stripe runs between the test on sh->count and device_lock being taken. This will mean that sh->lru is not empty while get_active_stripe thinks ->count is zero resulting in a 'BUG' firing. Another race happens if __release_stripe is called immediately after sh->count is tested and found to be non-zero. If STRIPE_HANDLE is not set, get_active_stripe should increment ->active_stripes when it increments ->count from 0, but as it didn't think it was 0, it doesn't. Extending device_lock to cover the test on sh->count close these races. While we are here, fix the two BUG tests: -If count is zero, then lru really must not be empty, or we've lock the stripe_head somehow - no other tests are relevant. -STRIPE_ON_RELEASE_LIST is completely independent of ->lru so testing it is pointless.

e605b36 Tejun Heo 27 November 2013, 23:16:21 UTC cgroup: fix cgroup_subsys_state leak for seq_files If a cgroup file implements either read_map() or read_seq_string(), such file is served using seq_file by overriding file->f_op to cgroup_seqfile_operations, which also overrides the release method to single_release() from cgroup_file_release(). Because cgroup_file_open() didn't use to acquire any resources, this used to be fine, but since f7d58818ba42 ("cgroup: pin cgroup_subsys_state when opening a cgroupfs file"), cgroup_file_open() pins the css (cgroup_subsys_state) which is put by cgroup_file_release(). The patch forgot to update the release path for seq_files and each open/release cycle leaks a css reference. Fix it by updating cgroup_file_release() to also handle seq_files and using it for seq_file release path too.

Now, after commit bcdde7e221a8, the sysfs directory is removed along with all of its subdirectories that include the SCSI host's sysfs directory and its subdirectories at this point. Consequently, when device_del() is finally called for any child device of the SCSI host and tries to remove its "power" group (which is already gone then), it triggers the above warning. To make the warnings go away, change the removal ordering in ata_port_detach() so that the SCSI host is removed from the port before ata_tport_delete() is called.

ced4cef Takashi Iwai 26 November 2013, 07:33:45 UTC ALSA: hda - Create Headhpone Mic Jack Mode when really needed When a headphone jack is configurable as input, the generic parser tries to make it retaskable as Headphone Mic. The switching can be done smoothly if Capture Source control exists (i.e. there is another input source). Or when user explicitly enables the creation of jack mode controls, "Headhpone Mic Jack Mode" will be created accordingly. However, if the headphone mic is the only input source, we have to create "Headphone Mic Jack Mode" control because there is no capture source selection. Otherwise, the generic parser assumes that the input is constantly enabled, thus the headphone is permanently set as input. This situation happens on the old MacBook Airs where no input is supported properly, for example. This patch fixes the problem: now "Headphone Mic Jack Mode" is created when such an input selection isn't possible.

I had some problem reproducing the crash, as the devm_kzalloc():ed zeroed memory would seemingly mask the spinlock as something OK, but by poisoning the lock like this: u32 *dum; dum = (u32 *) &chip->lock; *dum = 0xaaaaaaaaU; I could reproduce, fix and test the patch.

Well, it covered the function tracer by adding checks in __register_ftrace_function(). The problem is that the function graph tracer circumvents that (for a slight efficiency gain when function graph trace is running with a function tracer. The gain was not worth this). The problem came with ftrace_startup() which should always be called after __register_ftrace_function(), if you want this bug to be completely fixed. Anyway, this solution moves __register_ftrace_function() inside of ftrace_startup() and removes the need to call them both.

Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

33cb667 Dave Martin 25 November 2013, 16:16:25 UTC ARM: vexpress/TC2: Implement MCPM power_down_finish() This patch implements the power_down_finish() method for TC2, to enable the kernel to confirm when CPUs are safely powered down. The information required for determining when a CPU is parked cannot be obtained from any single place, so a few sources of information must be combined: * mcpm_cpu_power_down() must be pending for the CPU, so that we don't get confused by false STANDBYWFI positives arising from CPUidle. This is detected by waiting for the tc2_pm use count for the target CPU to reach 0. * Either the SPC must report that the CPU has asserted STANDBYWFI, or the TC2 tile's reset control logic must be holding the CPU in reset. Just checking for STANDBYWFI is not sufficient, because this signal is not latched when the the cluster is clamped off and powered down: the relevant status bits just drop to zero. This means that STANDBYWFI status cannot be used for reliable detection of the last CPU in a cluster reaching WFI. This patch is required in order for kexec to work with MCPM on TC2. MCPM code was changed in commit 0de0d6467525 ('ARM: 7848/1: mcpm: Implement cpu_kill() to synchronise on powerdown'), and since then it will hit a WARN_ON_ONCE() due to power_down_finish not being implemented on the TC2 platform.

The usual mixed bag of fixes. * 3 cases where kconfig dependencies were missing. We need to keep a closer eye on this in new drivers. * hid_sensors was abusing the iio_dev->trigger pointer. We had a round of clearing this out some time ago but this driver clearly slipped through. * A misuse of the IIO_ST macro, in mcp3422, which we should really make a concertive effort to finish removing. * Avoid a double free introduced by recent buffer reference counting in the one driver that (quite reasonably!) does things differently (am335x) * A missing mutex_unlock in kxsd9 that means that driver has been non functional for some time and no one noticed (including me who for once actually has one of the supported devices). * An incorrect assumption about the parameters of sign_extend32 in mcp3422. So nothing controversial. The only substantial patch is the hid_sensors one and that is actually just adding a new pointer to the devices private state then moving the code over to it. 25 November 2013, 20:50:11 UTC
