commit 1539d4f8 upstream. When recording at 176.2KHz or 192Khz, the device adds a 32-bit length header to the capture packets, which obviously needs to be ignored for recording to work properly. Userspace expected: L0 L1 L2 R0 R1 R2 ...but actually got: R2 L0 L1 L2 R0 R1 Also, the last byte of the length header being interpreted as L0 of the first sample caused spikes every 0.5ms, resulting in a loud 16KHz tone (about the highest 'B' on a piano) being present throughout captures. Tested at all sample rates on an E-Mu 0404USB, and tested for regressions on a generic USB headset.

commit 80da2e0d upstream. When a whole class of devices (possibly from a specific vendor, or across multiple vendors) require a quirk, explictly listing all devices in the class make the quirks table unnecessarily large.

commit 2656a9ab upstream. This patch (as1632b) fixes a bug in ehci-hcd. The USB core uses urb->hcpriv to determine whether or not an URB is active; host controller drivers are supposed to set this pointer to a non-NULL value when an URB is queued. However ehci-hcd sets it to NULL for isochronous URBs, which defeats the check in usbcore. In itself this isn't a big deal. But people have recently found that certain sequences of actions will cause the snd-usb-audio driver to reuse URBs without waiting for them to complete. In the absence of proper checking by usbcore, the URBs get added to their endpoint list twice. This leads to list corruption and a system freeze. The patch makes ehci-hcd assign a meaningful value to urb->hcpriv for isochronous URBs. Improving robustness always helps. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Reported-by: Artem S.

commit 838f4279 upstream. The ath9k commit 2ef16755 (ath9k: fix signal strength reporting issues) fixed an issue where the reported per-frame signal strength reported to mac80211 was being overwritten with an internal average. The same issue is also present in ath9k_htc. In addition to preventing the driver from overwriting the value, this commit also ensures that the internal average (which is used for ANI) only tracks beacons of the AP that we're connected to.

commit 696df785 upstream. The commits, "ath9k: Fix regression in channelwidth switch at the same channel" "ath9k: Fix invalid noisefloor reading due to channel update" attempted to fix noisefloor calibration when a channel switch happens due to HT20/HT40 bandwidth change. This is causing invalid readings resulting in messages like: "ath: phy16: NF[0] (-45) > MAX (-95), correcting to MAX". This results in an incorrect noise being used initially for reporting the signal level of received packets, until NF calibration is done and the history buffer is updated via the ANI timer, which happens much later. When a bandwidth change happens, it is appropriate to reset the internal history data for the channel. Do this correctly in the reset() routine by checking the "chanmode" variable.

commit acfdd4b1 upstream. a.out support on ARM requires that argc, argv and envp are passed in r0-r2 respectively, which requires hacking load_aout_binary to prevent argc being clobbered by the return code. Whilst mainline kernels do set the registers up in start_thread, the aout loader has never carried the hack in mainline. Initialising the registers in this way actually goes against the libc expectations for ELF binaries, where argc, argv and envp are passed on the stack, with r0 being used to hold a pointer to an exit function for cleaning up after the dynamic linker if required. If the pointer is NULL, then it is ignored. When execing an ELF binary, Linux currently zeroes r0, then sets it to argc and then finally clobbers it with the return value of the execve syscall, so we actually end up with: r0 = 0 stack[0] = argc r1 = stack[1] = argv r2 = stack[2] = envp libc treats r1 and r2 as undefined. The clobbering of r0 by sys_execve works for user-spawned threads, but when executing an ELF binary from a kernel thread (via call_usermodehelper), the execve is performed on the ret_from_fork path, which restores r0 from the saved pt_regs, resulting in argc being presented to the C library. This has horrible consequences when the application exits, since we have an exit function registered using argc, resulting in a jump to hyperspace. This patch solves the problem by removing the partial a.out support from arch/arm/ altogether.

commit 6f16f499 upstream. We currently use a temporary 1MB section aligned to a 1MB boundary for mapping the provided device tree until the final page table is created. However, if the device tree happens to cross that 1MB boundary, the end of it remains unmapped and the kernel crashes when it attempts to access it. Given no restriction on the location of that DTB, it could end up with only a few bytes mapped at the end of a section. Solve this issue by mapping two consecutive sections.

commit ff88b472 upstream. Erratum 71 of PXA270M Processor Family Specification Update (April 19, 2010) explains that watchdog reset time is just 8us insead of 10ms in EMTS. If SDRAM is not reset, it causes memory bus congestion and the device hangs. We put SDRAM in selfresh mode before watchdog reset, removing potential freezes. Without this patch PXA270-based ICP DAS LP-8x4x hangs after up to 40 reboots. With this patch it has successfully rebooted 500 times.

commit da94a829 upstream. In August 2012, Matthew Gretton-Dann checked a change into binutils labelled "Error on obsolete & warn on deprecated registers", apparently as part of ARMv8 support. Apparently, this was supposed to emit the message "Warning: This coprocessor register access is deprecated in ARMv8" when using certain mcr/mrc instructions and building for ARMv8. Unfortunately, the message that is actually emitted appears to be '(null)', which is less helpful in comparison. Even more unfortunately, this is biting us on every single kernel build with a new gas, because arch/arm/boot/compressed/head.S and some other files in that directory are built with -march=all since kernel commit 80cec14a "[ARM] Add -march=all to assembly file build in arch/arm/boot/compressed" back in v2.6.28. This patch reverts Russell's nice solution and instead marks the head.S file to be built for armv7-a, which fortunately lets us build all instructions in that file without warnings even on the broken binutils. Without this patch, building anything results in: arch/arm/boot/compressed/head.S: Assembler messages: arch/arm/boot/compressed/head.S:565: Warning: (null) arch/arm/boot/compressed/head.S:676: Warning: (null) arch/arm/boot/compressed/head.S:698: Warning: (null) arch/arm/boot/compressed/head.S:722: Warning: (null) arch/arm/boot/compressed/head.S:726: Warning: (null) arch/arm/boot/compressed/head.S:957: Warning: (null) arch/arm/boot/compressed/head.S:996: Warning: (null) arch/arm/boot/compressed/head.S:997: Warning: (null) arch/arm/boot/compressed/head.S:1027: Warning: (null) arch/arm/boot/compressed/head.S:1035: Warning: (null) arch/arm/boot/compressed/head.S:1046: Warning: (null) arch/arm/boot/compressed/head.S:1060: Warning: (null) arch/arm/boot/compressed/head.S:1092: Warning: (null) arch/arm/boot/compressed/head.S:1094: Warning: (null) arch/arm/boot/compressed/head.S:1095: Warning: (null) arch/arm/boot/compressed/head.S:1102: Warning: (null) arch/arm/boot/compressed/head.S:1134: Warning: (null) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Matthew Gretton-Dann <matthew.gretton-dann@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> [bwh: Backported to 3.2: - Adjust context - Remove definition of asflags-y as it is now empty] Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Cc: Yang Yingliang <yangyingliang@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

When a device is unplugged, wait for all processes that have opened the device to close before deallocating the device. This commit was solving kernel crash because of the corruption in rb tree of vmalloc. The rootcause was the device data pointer was geting excessed after the memory associated with hidraw was freed. The commit 4fe9f8e2 was buggy as it was also freeing the hidraw first and then calling delete operation on the list associated with that hidraw leading to slab corruption.

commit a4649184 upstream. Some Vaio desktop computers, among them the VGC-LN51JGB multimedia PC, have a RF receiver, multi-interface USB device 054c:0374, that is used to connect a wireless keyboard and a wireless mouse. The keyboard works flawlessly, but the mouse (VGP-WMS3 in my case) does not seem to be generating any pointer events. The problem is that the mouse pointer is wrongly declared as a constant non-data variable in the report descriptor (see lsusb and usbhid-dump output below), with the consequence that it is ignored by the HID code. Add this device to the have-special-driver list and fix up the report descriptor in the Sony-specific driver which happens to already have a fixup for a similar firmware bug. # lsusb -vd 054C:0374 Bus 003 Device 002: ID 054c:0374 Sony Corp.

commit f64410ec upstream. This patch is based on an earlier patch by Eric Paris, he describes the problem below: "If an inode is accessed before policy load it will get placed on a list of inodes to be initialized after policy load. After policy load we call inode_doinit() which calls inode_doinit_with_dentry() on all inodes accessed before policy load. In the case of inodes in procfs that means we'll end up at the bottom where it does: /* Default to the fs superblock SID. */ isec->sid = sbsec->sid; if ((sbsec->flags & SE_SBPROC) && !S_ISLNK(inode->i_mode)) { if (opt_dentry) { isec->sclass = inode_mode_to_security_class(...) rc = selinux_proc_get_sid(opt_dentry, isec->sclass, &sid); if (rc) goto out_unlock; isec->sid = sid; } } Since opt_dentry is null, we'll never call selinux_proc_get_sid() and will leave the inode labeled with the label on the superblock. I believe a fix would be to mimic the behavior of xattrs. Look for an alias of the inode. If it can't be found, just leave the inode uninitialized (and pick it up later) if it can be found, we should be able to call selinux_proc_get_sid() ..." On a system exhibiting this problem, you will notice a lot of files in /proc with the generic "proc_t" type (at least the ones that were accessed early in the boot), for example: # ls -Z /proc/sys/kernel/shmmax | awk '{ print $4 " " $5 }' system_u:object_r:proc_t:s0 /proc/sys/kernel/shmmax However, with this patch in place we see the expected result: # ls -Z /proc/sys/kernel/shmmax | awk '{ print $4 " " $5 }' system_u:object_r:sysctl_kernel_t:s0 /proc/sys/kernel/shmmax Cc: Eric Paris <eparis@redhat.com> Signed-off-by: Paul Moore <pmoore@redhat.com> Acked-by: Eric Paris <eparis@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit d953e0e8 upstream. Remove the cdev from the system (with cdev_del) *before* deallocating it (in pps_device_destruct, called via kobject_put from device_destroy). Also prevent deallocating a device with open file handles. A better long-term fix is probably to remove the cdev from the pps_device entirely, and instead have all devices reference one global cdev. Then the deallocation ordering becomes simpler. But that's more complex and invasive change, so we leave that for later.
