The AES-CTR glue code avoids calling into the blkcipher API for the tail portion of the walk, by comparing the remainder of walk.nbytes modulo AES_BLOCK_SIZE with the residual nbytes, and jumping straight into the tail processing block if they are equal. This tail processing block checks whether nbytes != 0, and does nothing otherwise. However, in case of an allocation failure in the blkcipher layer, we may enter this code with walk.nbytes == 0, while nbytes > 0. In this case, we should not dereference the source and destination pointers, since they may be NULL. So instead of checking for nbytes != 0, check for (walk.nbytes % AES_BLOCK_SIZE) != 0, which implies the former in non-error conditions.

When we need to allocate a temporary blkcipher_walk_next and it fails, the code is supposed to take the slow path of processing the data block by block. However, due to an unrelated change we instead end up dereferencing the NULL pointer. This patch fixes it by moving the unrelated bsize setting out of the way so that we enter the slow path as inteded.

To be able to generate shared descriptors for AEAD, the authentication size needs to be known. However, there is no imposed order of calling .setkey, .setauthsize callbacks.

There are a few things missed by the conversion to the new AEAD interface: 1 - echainiv(authenc) encrypt shared descriptor The shared descriptor is incorrect: due to the order of operations, at some point in time MATH3 register is being overwritten. 2 - buffer used for echainiv(authenc) encrypt shared descriptor Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually exclusive and thus use the same buffer in context state: sh_desc_enc. However, there's one place missed by s/sh_desc_givenc/sh_desc_enc, leading to errors when echainiv(authenc(...)) algorithms are used: DECO: desc idx 14: Header Error. Invalid length or parity, or certain other problems. While here, also fix a typo: dma_mapping_error() is checking for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

Commit abf54548 changed it from an 'rw' flags type to the newer ops based interface, but now we're effectively leaking some bdev internals to the rest of the kernel. Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead.

Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs Pull more xfs updates from Dave Chinner: "This is the second part of the XFS updates for this merge cycle, and contains the new reverse block mapping feature for XFS. Reverse mapping allows us to track the owner of a specific block on disk precisely. It is implemented as a set of btrees (one per allocation group) that track the owners of allocated extents. Effectively it is a "used space tree" that is updated when we allocate or free extents. i.e. it is coherent with the free space btrees we already maintain and never overlaps with them. This reverse mapping infrastructure is the building block of several upcoming features - reflink, copy-on-write data, dedupe, online metadata and data scrubbing, highly accurate bad sector/data loss reporting to users, and significantly improved reconstruction of damaged and corrupted filesystems. There's a lot of new stuff coming along in the next couple of cycles,a nd it all builds in the rmap infrastructure. As such, it's a huge chunk of new code with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time kernel with this code in it is released. The new rmap enabled code regresses 3 xfstests - all are ENOSPC related corner cases, one of which Darrick posted a fix for a few hours ago. The other two are fixed by infrastructure that is part of the upcoming reflink patchset. This new ENOSPC infrastructure requires a on-disk format tweak required to keep mount times in check - we need to keep an on-disk count of allocated rmapbt blocks so we don't have to scan the entire btrees at mount time to count them. This is currently being tested and will be part of the fixes sent in the next week or two so users will not be exposed to this change" * tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (52 commits) xfs: move (and rename) the deferred bmap-free tracepoints xfs: collapse single use static functions xfs: remove unnecessary parentheses from log redo item recovery functions xfs: remove the extents array from the rmap update done log item xfs: in btree_lshift, only allocate temporary cursor when needed xfs: remove unnecesary lshift/rshift key initialization xfs: remove the get*keys and update_keys btree ops pointers xfs: enable the rmap btree functionality xfs: don't update rmapbt when fixing agfl xfs: disable XFS_IOC_SWAPEXT when rmap btree is enabled xfs: add rmap btree block detection to log recovery xfs: add rmap btree geometry feature flag xfs: propagate bmap updates to rmapbt xfs: enable the xfs_defer mechanism to process rmaps to update xfs: log rmap intent items xfs: create rmap update intent log items xfs: add rmap btree insert and delete helpers xfs: convert unwritten status of reverse mappings xfs: remove an extent from the rmap btree xfs: add an extent to the rmap btree ...

David says, there are no compatibility issues raised by this fix. - Move some signal code around. - Rewrite r4k count/compare clockevent device registration such that min_delta_ticks/max_delta_ticks files are guaranteed to be initialized. - Only register r4k count/compare as clockevent device if we can assume the clock to be constant. - Fix MSA asm warnings in control reg accessors - uasm and tlbex fixes and tweaking. - Print segment physical address when EU=1. - Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO. - CP: Allow booting by VP other than VP 0 - Cache handling fixes and optimizations for r4k class caches - Add hotplug support for R6 processors - Cleanup hotplug bits in kconfig - traps: return correct si code for accessing nonmapped addresses - Remove cpu_has_safe_index_cacheops Lantiq: - Register IRQ handler for virtual IRQ number - Fix EIU interrupt loading code - Use the real EXIN count - Fix build error. Loongson 3: - Increase HPET_MIN_PROG_DELTA and decrease HPET_MIN_CYCLES Octeon: - Delete built-in DTB pruning code for D-Link DSR-1000N. - Clean up GPIO definitions in dlink_dsr-1000n.dts. - Add more LEDs to the DSR-100n DTS - Fix off by one in octeon_irq_gpio_map() - Typo fixes - Enable SATA by default in cavium_octeon_defconfig - Support readq/writeq() - Remove forced mappings of USB interrupts. - Ensure DMA descriptors are always in the low 4GB - Improve USB reset code for OCTEON II. Pistachio: - Add maintainers entry for pistachio SoC Support - Remove plat_setup_iocoherency Ralink: - Fix pwm UART in spis group pinmux. SSB: - Change bare unsigned to unsigned int to suit coding style Tools: - Fix reloc tool compiler warnings. Other: - Delete use of ARCH_WANT_OPTIONAL_GPIOLIB" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (61 commits) MIPS: mm: Fix definition of R6 cache instruction MIPS: tools: Fix relocs tool compiler warnings MIPS: Cobalt: Fix typo MIPS: Octeon: Fix typo MIPS: Lantiq: Fix build failure MIPS: Use CPHYSADDR to implement mips32 __pa MIPS: Octeon: Dlink_dsr-1000n.dts: add more leds.
