2016-01-25btrfs: async-thread: Fix a use-after-free error for traceQu Wenruo
Parameter of trace_btrfs_work_queued() can be freed in its workqueue. So no one use use that pointer after queue_work(). Fix the user-after-free bug by move the trace line before queue_work().

2016-01-25Btrfs: fix race between fsync and lockless direct IO writesFilipe Manana
An fsync, using the fast path, can race with a concurrent lockless direct IO write and end up logging a file extent item that points to an extent that wasn't written to yet. This is because the fast fsync path collects ordered extents into a local list and then collects all the new extent maps to log file extent items based on them, while the direct IO write path creates the new extent map before it creates the corresponding ordered extent (and submitting the respective bio(s)). So fix this by making the direct IO write path create ordered extents before the extent maps and make the fast fsync path collect any new ordered extents after it collects the extent maps. Note that making the fsync handler call inode_dio_wait() (after acquiring the inode's i_mutex) would not work and lead to a deadlock when doing AIO, as through AIO we end up in a path where the fsync handler is called (through dio_aio_complete_work() -> dio_complete() -> vfs_fsync_range()) before the inode's dio counter is decremented (inode_dio_wait() waits for this counter to have a value of zero).

2016-01-25ALSA: compress: Disable GET_CODEC_CAPS ioctl for some architecturesTakashi Iwai
Some architectures like PowerPC can handle the maximum struct size in an ioctl only up to 13 bits, and struct snd_compr_codec_caps used by SNDRV_COMPRESS_GET_CODEC_CAPS ioctl overflows this limit. This problem was revealed recently by a powerpc change, as it's now treated as a fatal build error. This patch is a stop-gap for that: for architectures with less than 14 bit ioctl struct size, get rid of the handling of the relevant ioctl. We should provide an alternative equivalent ioctl code later, but for now just paper over it. Luckily, the compress API hasn't been used on such architectures, so the impact must be effectively zero.

2016-01-25arm64: Honour !PTE_WRITE in set_pte_at() for kernel mappingsCatalin Marinas
Currently, set_pte_at() only checks the software PTE_WRITE bit for user mappings when it sets or clears the hardware PTE_RDONLY accordingly. The kernel ptes are written directly without any modification, relying solely on the protection bits in macros like PAGE_KERNEL. However, modifying kernel pte attributes via pte_wrprotect() would be ignored by set_pte_at(). Since pte_wrprotect() does not set PTE_RDONLY (it only clears PTE_WRITE), the new permission is not taken into account. This patch changes set_pte_at() to adjust the read-only permission for kernel ptes as well. As a side effect, existing PROT_* definitions used for kernel ioremap*() need to include PTE_DIRTY | PTE_WRITE.

2016-01-25arm64: hide __efistub_ aliases from kallsymsArd Biesheuvel
Commit e8f3010f7326 ("arm64/efi: isolate EFI stub from the kernel proper") isolated the EFI stub code from the kernel proper by prefixing all of its symbols with __efistub_, and selectively allowing access to core kernel symbols from the stub by emitting __efistub_ aliases for functions and variables that the stub can access legally. As an unintended side effect, these aliases are emitted into the kallsyms symbol table, which means they may turn up in backtraces, e.g., ... PC is at __efistub_memset+0x108/0x200 LR is at fixup_init+0x3c/0x48 ... [<ffffff8008328608>] __efistub_memset+0x108/0x200 [<ffffff8008094dcc>] free_initmem+0x2c/0x40 [<ffffff8008645198>] kernel_init+0x20/0xe0 [<ffffff8008085cd0>] ret_from_fork+0x10/0x40 The backtrace in question has nothing to do with the EFI stub, but simply returns one of the several aliases of memset() that have been recorded in the kallsyms table. This is undesirable, since it may suggest to people who are not aware of this that the issue they are seeing is somehow EFI related. So hide the __efistub_ aliases from kallsyms, by emitting them as absolute linker symbols explicitly. The distinction between those and section relative symbols is completely irrelevant to these definitions, and to the final link we are performing when these definitions are being taken into account (the distinction is only relevant to symbols defined inside a section definition when performing a partial link), and so the resulting values are identical to the original ones. Since absolute symbols are ignored by kallsyms, this will result in these values to be omitted from its symbol table. After this patch, the backtrace generated from the same address looks like this: ... PC is at __memset+0x108/0x200 LR is at fixup_init+0x3c/0x48 ... [<ffffff8008328608>] __memset+0x108/0x200 [<ffffff8008094dcc>] free_initmem+0x2c/0x40 [<ffffff8008645198>] kernel_init+0x20/0xe0 [<ffffff8008085cd0>] ret_from_fork+0x10/0x40 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Will Deacon <will.deacon@arm.com>

Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS for 4.5 plus some 4.4 fixes. The executive summary: - ATH79 platform improvments, use DT bindings for the ATH79 USB PHY. - Avoid useless rebuilds for zboot. - jz4780: Add NEMC, BCH and NAND device tree nodes - Initial support for the MicroChip's DT platform. As all the device drivers are missing this is still of limited use. - Some Loongson3 cleanups. - The unavoidable whitespace polishing. - Reduce clock skew when synchronizing the CPU cycle counters on CPU startup. - Add MIPS R6 fixes. - Lots of cleanups across arch/mips as fallout from KVM. - Lots of minor fixes and changes for IEEE 754-2008 support to the FPU emulator / fp-assist software. - Minor Ralink, BCM47xx and bcm963xx platform support improvments. - Support SMP on BCM63168" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (84 commits) MIPS: zboot: Add support for serial debug using the PROM MIPS: zboot: Avoid useless rebuilds MIPS: BMIPS: Enable ARCH_WANT_OPTIONAL_GPIOLIB MIPS: bcm63xx: nvram: Remove unused bcm63xx_nvram_get_psi_size() function MIPS: bcm963xx: Update bcm_tag field image_sequence MIPS: bcm963xx: Move extended flash address to bcm_tag header file MIPS: bcm963xx: Move Broadcom BCM963xx image tag data structure MIPS: bcm63xx: nvram: Use nvram structure definition from header file MIPS: bcm963xx: Add Broadcom BCM963xx board nvram data structure MAINTAINERS: Add KVM for MIPS entry MIPS: KVM: Add missing newline to kvm_err() MIPS: Move KVM specific opcodes into asm/inst.h MIPS: KVM: Use cacheops.h definitions MIPS: Break down cacheops.h definitions MIPS: Use EXCCODE_ constants with set_except_vector() MIPS: Update trap codes MIPS: Move Cause.ExcCode trap codes to mipsregs.h MIPS: KVM: Make kvm_mips_{init,exit}() static MIPS: KVM: Refactor added offsetof()s MIPS: KVM: Convert EXPORT_SYMBOL to _GPL ...

2016-01-24ideapad-laptop: Add Lenovo Yoga 700 to no_hw_rfkill dmi listJosh Boyer
Like the Yoga 900 models the Lenovo Yoga 700 does not have a hw rfkill switch, and trying to read the hw rfkill switch through the ideapad module causes it to always reported blocking breaking wifi. This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing the wifi breakage.
