2016-07-28Merge branch 'salted-string-hash'Linus Torvalds
This changes the vfs dentry hashing to mix in the parent pointer at the _beginning_ of the hash, rather than at the end. That actually improves both the hash and the code generation, because we can move more of the computation to the "static" part of the dcache setup, and do less at lookup runtime. It turns out that a lot of other hash users also really wanted to mix in a base pointer as a 'salt' for the hash, and so the slightly extended interface ends up working well for other cases too. Users that want a string hash that is purely about the string pass in a 'salt' pointer of NULL. * merge branch 'salted-string-hash': fs/dcache.c: Save one 32-bit multiply in dcache lookup vfs: make the string hashes salt the hash
2016-07-28pNFS: Actively set attributes as invalid if LAYOUTCOMMIT is outstandingBenjamin Coddington
A LAYOUTCOMMIT then subsequent GETATTR may both return the same attributes, and in that case NFS_INO_INVALID_ATTR is never set on the second pass through nfs_update_inode(). The existing check to skip the clearing of NFS_INO_INVALID_ATTR if a LAYOUTCOMMIT is outstanding does not help in this case (see commit 10b7e9ad4488: "pNFS: Don't mark the inode as revalidated if a LAYOUTCOMMIT is outstanding"). We know that if a LAYOUTCOMMIT is outstanding then attributes will need upating, so always set NFS_INO_INVALID_ATTR.

2016-07-28crypto: marvell - Update cache with input sg only when it is unmappedRomain Perier
So far, the cache of the ahash requests was updated from the 'complete' operation. This complete operation is called from mv_cesa_tdma_process before the cleanup operation, which means that the content of req->src can be read and copied when it is still mapped. This commit fixes the issue by moving this cache update from mv_cesa_ahash_complete to mv_cesa_ahash_req_cleanup, so the copy is done once the sglist is unmapped.

2016-07-27Add braces to avoid "ambiguous ‘else’" compiler warningsLinus Torvalds
Some of our "for_each_xyz()" macro constructs make gcc unhappy about lack of braces around if-statements inside or outside the loop, because the loop construct itself has a "if-then-else" statement inside of it. The resulting warnings look something like this: drivers/gpu/drm/i915/i915_debugfs.c: In function ‘i915_dump_lrc’: drivers/gpu/drm/i915/i915_debugfs.c:2103:6: warning: suggest explicit braces to avoid ambiguous ‘else’ [-Wparentheses] if (ctx != dev_priv->kernel_context) ^ even if the code itself is fine. Since the warning is fairly easy to avoid by adding a braces around the if-statement near the for_each_xyz() construct, do so, rather than disabling the otherwise potentially useful warning. (The if-then-else statements used in the "for_each_xyz()" constructs are designed to be inherently safe even with no braces, but in this case it's quite understandable that gcc isn't really able to tell that). This finally leaves the standard "allmodconfig" build with just a handful of remaining warnings, so new and valid warnings hopefully will stand out.

2016-07-27Disable "frame-address" warningLinus Torvalds
Newer versions of gcc warn about the use of __builtin_return_address() with a non-zero argument when "-Wall" is specified: kernel/trace/trace_irqsoff.c: In function ‘stop_critical_timings’: kernel/trace/trace_irqsoff.c:433:86: warning: calling ‘__builtin_return_address’ with a nonzero argument is unsafe [-Wframe-address] stop_critical_timing(CALLER_ADDR0, CALLER_ADDR1); [ .. repeats a few times for other similar cases .. ] It is true that a non-zero argument is somewhat dangerous, and we do not actually have very many uses of that in the kernel - but the ftrace code does use it, and as Stephen Rostedt says: "We are well aware of the danger of using __builtin_return_address() of > 0. In fact that's part of the reason for having the "thunk" code in x86 (See arch/x86/entry/thunk_{64,32}.S). [..] it adds extra frames when tracking irqs off sections, to prevent __builtin_return_address() from accessing bad areas. In fact the thunk_32.S states: 'Trampoline to trace irqs off. (otherwise CALLER_ADDR1 might crash)'." For now, __builtin_return_address() with a non-zero argument is the best we can do, and the warning is not helpful and can end up making people miss other warnings for real problems. So disable the frame-address warning on compilers that need it. Acked-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2016-07-27sparc: Don't leak context bits into thread->fault_addressDavid S. Miller
On pre-Niagara systems, we fetch the fault address on data TLB exceptions from the TLB_TAG_ACCESS register. But this register also contains the context ID assosciated with the fault in the low 13 bits of the register value. This propagates into current_thread_info()->fault_address and can cause trouble later on. So clear the low 13-bits out of the TLB_TAG_ACCESS value in the cases where it matters.

git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random Pull random driver updates from Ted Ts'o: "A number of improvements for the /dev/random driver; the most important is the use of a ChaCha20-based CRNG for /dev/urandom, which is faster, more efficient, and easier to make scalable for silly/abusive userspace programs that want to read from /dev/urandom in a tight loop on NUMA systems. This set of patches also improves entropy gathering on VM's running on Microsoft Azure, and will take advantage of a hw random number generator (if present) to initialize the /dev/urandom pool" (It turns out that the random tree hadn't been in linux-next this time around, because it had been dropped earlier as being too quiet.

Confusion between these two caused us to have scenarios where we were dropping locks. These are fixed by splitting into two separate locks like should have been done originally, making everything much clearer and correct. - Support for DMA in spi_flash_read(). - Support for instantiating spidev on ACPI systems, including some test devices used in Windows validation. - Use of the core DMA mapping functionality in the McSPI driver. - Start of support for ThunderX SPI controllers, involving a very big set of changes to the Cavium driver. - Support for Braswell, Exynos 5433, Kaby Lake, Merrifield, RK3036, RK3228, RK3368 controllers" * tag 'spi-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (64 commits) spi: Split bus and I/O locking spi: octeon: Split driver into Octeon specific and common parts spi: octeon: Move include file from arch/mips to drivers/spi spi: octeon: Put register offsets into a struct spi: octeon: Store system clock freqency in struct octeon_spi spi: octeon: Convert driver to use readq()/writeq() functions spi: pic32-sqi: fixup wait_for_completion_timeout return handling spi: pic32: fixup wait_for_completion_timeout return handling spi: rockchip: limit transfers to (64K - 1) bytes spi: xilinx: Return IRQ_NONE if no interrupts were detected spi: xilinx: Handle errors from platform_get_irq() spi: s3c64xx: restore removed comments spi: s3c64xx: add Exynos5433 compatible for ioclk handling spi: s3c64xx: use error code from clk_prepare_enable() spi: s3c64xx: rename goto labels to meaningful names spi: s3c64xx: document the clocks and the clock-name property spi: s3c64xx: add exynos5433 spi compatible spi: s3c64xx: fix reference leak to master in s3c64xx_spi_remove() spi: spi-sh: Remove deprecated create_singlethread_workqueue spi: spi-topcliff-pch: Remove deprecated create_singlethread_workqueue ...
