Add a driver for the ZIP engine found on Cavium ThunderX SOCs. The ZIP engine supports hardware accelerated compression and decompression. It includes 2 independent ZIP cores and supports: - DEFLATE compression and decompression (RFC 1951) - LZS compression and decompression (RFC 2395 and ANSI X3.241-1994) - ADLER32 and CRC32 checksums for ZLIB (RFC 1950) and GZIP (RFC 1952) The ZIP engine is presented as a PCI device. It supports DMA and scatter-gather. Signed-off-by:

To prevent unnecessary branching, mark the exit condition of the primary loop as likely(), given that a carry in a 32-bit counter occurs very rarely. On arm64, the resulting code is emitted by GCC as 9a8: cmp w1, #0x3 9ac: add x3, x0, w1, uxtw 9b0: b.ls 9e0 <crypto_inc+0x38> 9b4: ldr w2, [x3,#-4]! 9b8: rev w2, w2 9bc: add w2, w2, #0x1 9c0: rev w4, w2 9c4: str w4, [x3] 9c8: cbz w2, 9d0 <crypto_inc+0x28> 9cc: ret where the two remaining branch conditions (one for size < 4 and one for the carry) are statically predicted as non-taken, resulting in optimal execution in the vast majority of cases. Also, replace the open coded alignment test with IS_ALIGNED(). Cc: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by:

Currently, the bit sliced NEON AES code for ARM has a link time dependency on the scalar ARM asm implementation, which it uses as a fallback to perform CBC encryption and the encryption of the initial XTS tweak. The bit sliced NEON code is both fast and time invariant, which makes it a reasonable default on hardware that supports it. However, the ARM asm code it pulls in is not time invariant, and due to the way it is linked in, cannot be overridden by the new generic time invariant driver. In fact, it will not be used at all, given that the ARM asm code registers itself as a cipher with a priority that exceeds the priority of the fixed time cipher. So remove the link time dependency, and allocate the fallback cipher via the crypto API. Note that this requires this driver's module_init call to be replaced with late_initcall, so that the (possibly generic) fallback cipher is guaranteed to be available when the builtin test is performed at registration time.

Though the GF(2^128) byte overflow tables were named the "lle" and "bbe" tables, they are not actually tied to these element formats specifically, but rather to particular a "bit endianness". For example, the bbe table is actually used for both bbe and ble multiplication. Therefore, rename the tables to "le" and "be" and update the comment to explain this.

In most cases this wasn't fatal but when combined with some of the cipher modes (like LRW) this caused recursion - starting the new encryption (s5p_aes_crypt()) while still holding the spinlock from previous round (s5p_aes_complete()). Beside that, the s5p_aes_interrupt() error handling path could execute two completions in case of error for RX and TX blocks. Rewrite the interrupt handling routine and the completion by: 1. Splitting the operations on scatterlist copies from s5p_aes_complete() into separate s5p_sg_done(). This still should be done under lock. The s5p_aes_complete() now only calls req->base.complete() and it has to be called outside of lock. 2. Moving the s5p_aes_complete() out of spinlock critical sections. In interrupt service routine s5p_aes_interrupts(), it appeared in few places, including error paths inside other functions called from ISR. This code was not so obvious to read so simplify it by putting the s5p_aes_complete() only within ISR level. Reported-by:

Thomas Petazzoni authored
The INTMASK_REG register does not exist on EIP76. Due to this, the call: omap_rng_write(priv, RNG_INTMASK_REG, RNG_SHUTDOWN_OFLO_MASK); ends up, through the reg_map_eip76[] array, in accessing the register at offset 0, which is the RNG_OUTPUT_0_REG. This by itself doesn't cause any problem, but clearly doesn't enable the interrupt as it was expected. On EIP76, the register that allows to enable the interrupt is RNG_CONTROL_REG. And just like RNG_INTMASK_REG, it's bit 1 of this register that allows to enable the shutdown_oflo interrupt.

Commit 38321242 ("hwrng: omap - Add device variant for SafeXcel IP-76 found in Armada 8K") added support for the SafeXcel IP-76 variant of the IP. This modification included getting a reference and enabling a clock. Unfortunately, this was done *after* writing to the RNG_INTMASK_REG register. This generally works fine when the driver is built-in because the clock might have been left enabled by the bootloader, but fails short when the driver is built as a module: it causes a system hang because a register is being accessed while the clock is not enabled. This commit fixes that by making the register access *after* enabling the clock. This issue was found by the kernelci.org testing effort.

In a regular interrupt handler driver was finishing the crypt/decrypt request by calling complete on crypto request. This is disallowed since converting to skcipher in commit b286d8b1 ("crypto: skcipher - Add skcipher walk interface") and causes a warning: WARNING: CPU: 0 PID: 0 at crypto/skcipher.c:430 skcipher_walk_first+0x13c/0x14c The interrupt is marked shared but in fact there are no other users sharing it. Thus the simplest solution seems to be to just use a threaded interrupt handler, after converting it to oneshot. Signed-off-by:

Turning on crypto self-tests on a POWER8 shows: alg: hash: Test 1 failed for crc32c-vpmsum 00000000: ff ff ff ff Comparing the code with the Intel CRC32c implementation on which ours is based shows that we are doing an init with 0, not ~0 as CRC32c requires. This probably wasn't caught because btrfs does its own weird open-coded initialisation. Initialise our internal context to ~0 on init. This makes the self-tests pass, and btrfs continues to work.

With Sphinx 1.5.3 I get the warning: WARNING: primary_domain 'C' not found, ignored. It seems that domain names in Sphinx are case-sensitive and for the C domain the name must be lower case. Signed-off-by:

Pull overlayfs updates from Miklos Szeredi: "Because copy up can take a long time, serialized copy ups could be a big performance bottleneck. This update allows concurrent copy up of regular files eliminating this potential problem. There are also minor fixes" * 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs: ovl: drop CAP_SYS_RESOURCE from saved mounter's credentials ovl: properly implement sync_filesystem() ovl: concurrent copy up of regular files ovl: introduce copy up waitqueue ovl: copy up regular file using O_TMPFILE ovl: rearrange code in ovl_copy_up_locked() ovl: check if upperdir fs supports O_TMPFILE

Pull vfs 'statx()' update from Al Viro. This adds the new extended stat() interface that internally subsumes our previous stat interfaces, and allows user mode to specify in more detail what kind of information it wants. It also allows for some explicit synchronization information to be passed to the filesystem, which can be relevant for network filesystems: is the cached value ok, or do you need open/close consistency, or what? From David Howells. Andreas Dilger points out that the first version of the extended statx interface was posted June 29, 2010: https://www.spinics.net/lists/linux-fsdevel/msg33831.html * 'rebased-statx' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: statx: Add a system call to make enhanced file info available

Pull block layer fixes from Jens Axboe: "A collection of fixes for this merge window, either fixes for existing issues, or parts that were waiting for acks to come in. This pull request contains: - Allocation of nvme queues on the right node from Shaohua. This was ready long before the merge window, but waiting on an ack from Bjorn on the PCI bit. Now that we have that, the three patches can go in. - Two fixes for blk-mq-sched with nvmeof, which uses hctx specific request allocations. This caused an oops. One part from Sagi, one part from Omar. - A loop partition scan deadlock fix from Omar, fixing a regression in this merge window. - A three-patch series from Keith, closing up a hole on clearing out requests on shutdown/resume. - A stable fix for nbd from Josef, fixing a leak of sockets. - Two fixes for a regression in this window from Jan, fixing a problem with one of his earlier patches dealing with queue vs bdi life times. - A fix for a regression with virtio-blk, causing an IO stall if scheduling is used. From me. - A fix for an io context lock ordering problem. From me" * 'for-linus' of git://git.kernel.dk/linux-block: block: Move bdi_unregister() to del_gendisk() blk-mq: ensure that bd->last is always set correctly block: don't call ioc_exit_icq() with the queue lock held for blk-mq block: Initialize bd_bdi on inode initialization loop: fix LO_FLAGS_PARTSCAN hang nvme: Complete all stuck requests blk-mq: Provide freeze queue timeout blk-mq: Export blk_mq_freeze_queue_wait nbd: stop leaking sockets blk-mq: move update of tags->rqs to __blk_mq_alloc_request() blk-mq: kill blk_mq_set_alloc_data() blk-mq: make blk_mq_alloc_request_hctx() allocate a scheduler request blk-mq-sched: Allocate sched reserved tags as specified in the original queue tagset nvme: allocate nvme_queue in correct node PCI: add an API to get node from vector blk-mq: allocate blk_mq_tags and requests in correct node

Pull sched.h split-up from Ingo Molnar: "The point of these changes is to significantly reduce the <linux/sched.h> header footprint, to speed up the kernel build and to have a cleaner header structure. After these changes the new <linux/sched.h>'s typical preprocessed size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K lines), which is around 40% faster to build on typical configs. Not much changed from the last version (-v2) posted three weeks ago: I eliminated quirks, backmerged fixes plus I rebased it to an upstream SHA1 from yesterday that includes most changes queued up in -next plus all sched.h changes that were pending from Andrew. I've re-tested the series both on x86 and on cross-arch defconfigs, and did a bisectability test at a number of random points. I tried to test as many build configurations as possible, but some build breakage is probably still left - but it should be mostly limited to architectures that have no cross-compiler binaries available on kernel.org, and non-default configurations" * 'WIP.sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (146 commits) sched/headers: Clean up <linux/sched.h> sched/headers: Remove #ifdefs from <linux/sched.h> sched/headers: Remove the <linux/topology.h> include from <linux/sched.h> sched/headers, hrtimer: Remove the <linux/wait.h> include from <linux/hrtimer.h> sched/headers, x86/apic: Remove the <linux/pm.h> header inclusion from <asm/apic.h> sched/headers, timers: Remove the <linux/sysctl.h> include from <linux/timer.h> sched/headers: Remove <linux/magic.h> from <linux/sched/task_stack.h> sched/headers: Remove <linux/sched.h> from <linux/sched/init.h> sched/core: Remove unused prefetch_stack() sched/headers: Remove <linux/rculist.h> from <linux/sched.h> sched/headers: Remove the 'init_pid_ns' prototype from <linux/sched.h> sched/headers: Remove <linux/signal.h> from <linux/sched.h> sched/headers: Remove <linux/rwsem.h> from <linux/sched.h> sched/headers: Remove the runqueue_is_locked() prototype sched/headers: Remove <linux/sched.h> from <linux/sched/hotplug.h> sched/headers: Remove <linux/sched.h> from <linux/sched/debug.h> sched/headers: Remove <linux/sched.h> from <linux/sched/nohz.h> sched/headers: Remove <linux/sched.h> from <linux/sched/stat.h> sched/headers: Remove the <linux/gfp.h> include from <linux/sched.h> sched/headers: Remove <linux/rtmutex.h> from <linux/sched.h> ...
