When convert char array with signed int, if the inbuf[x] is negative then upper bits will be set to 1. Fix this by using u8 instead of char. ret_size has to be at least 3, hid_input_report use it after minus 2 bytes.

Pull GPIO updates from Linus Walleij: "The is the bulk of GPIO changes for the v4.16 kernel cycle. It is pretty calm this time around I think. I even got time to get to things like starting to clean up header includes. Core changes: - Disallow open drain and open source flags to be set simultaneously. This doesn't make electrical sense, and would the hardware actually respond to this setting, the result would be short circuit. - ACPI GPIO has a new core infrastructure for handling quirks. The quirks are there to deal with broken ACPI tables centrally instead of pushing the work to individual drivers. In the world of BIOS writers, the ACPI tables are perfect. Until they find a mistake in it. When such a mistake is found, we can patch it with a quirk. It should never happen, the problem is that it happens. So we accomodate for it. - Several documentation updates. - Revert the patch setting up initial direction state from reading the device. This was causing bad things for drivers that can't read status on all its pins. It is only affecting debugfs information quality. - Label descriptors with the device name if no explicit label is passed in. - Pave the ground for transitioning SPI and regulators to use GPIO descriptors by implementing some quirks in the device tree GPIO parsing code. New drivers: - New driver for the Access PCIe IDIO 24 family. Other: - Major refactorings and improvements to the GPIO mockup driver used for test and verification. - Moved the AXP209 driver over to pin control since it gained a pin control back-end. These patches will appear (with the same hashes) in the pin control pull request as well. - Convert the onewire GPIO driver w1-gpio to use descriptors. This is merged here since the W1 maintainers send very few pull requests and he ACKed it. - Start to clean up driver headers using <linux/gpio.h> to just use <linux/gpio/driver.h> as appropriate" * tag 'gpio-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (103 commits) gpio: Timestamp events in hardirq handler gpio: Fix kernel stack leak to userspace gpio: Fix a documentation spelling mistake gpio: Documentation update gpiolib: remove redundant initialization of pointer desc gpio: of: Fix NPE from OF flags gpio: stmpe: Delete an unnecessary variable initialisation in stmpe_gpio_probe() gpio: stmpe: Move an assignment in stmpe_gpio_probe() gpio: stmpe: Improve a size determination in stmpe_gpio_probe() gpio: stmpe: Use seq_putc() in stmpe_dbg_show() gpio: No NULL owner gpio: stmpe: i2c transfer are forbiden in atomic context gpio: davinci: Include proper header gpio: da905x: Include proper header gpio: cs5535: Include proper header gpio: crystalcove: Include proper header gpio: bt8xx: Include proper header gpio: bcm-kona: Include proper header gpio: arizona: Include proper header gpio: amd8111: Include proper header ...

Pull RDMA subsystem updates from Jason Gunthorpe: "Overall this cycle did not have any major excitement, and did not require any shared branch with netdev. Lots of driver updates, particularly of the scale-up and performance variety. The largest body of core work was Parav's patches fixing and restructing some of the core code to make way for future RDMA containerization.

Pull xfs updates from Darrick Wong: "This merge cycle, we're again some substantive changes to XFS. Metadata verifiers have been restructured to provide more detail about which part of a metadata structure failed checks, and we've enhanced the new online fsck feature to cross-reference extent allocation information with the other metadata structures. With this pull, the metadata verification part of online fsck is more or less finished, though the feature is still experimental and still disabled by default. We're also preparing to remove the EXPERIMENTAL tag from a couple of features this cycle. This week we're committing a bunch of space accounting fixes for reflink and removing the EXPERIMENTAL tag from reflink; I anticipate that we'll be ready to do the same for the reverse mapping feature next week. (I don't have any pending fixes for rmap; however I wish to remove the tags one at a time.) This giant pile of patches has been run through a full xfstests run over the weekend and through a quick xfstests run against this morning's master, with no major failures reported. Let me know if there's any merge problems -- git merge reported that one of our patches touched the same function as the i_version series, but it resolved things cleanly. Summary: - Log faulting code locations when verifiers fail, for improved diagnosis of corrupt filesystems. - Implement metadata verifiers for local format inode fork data. - Online scrub now cross-references metadata records with other metadata. - Refactor the fs geometry ioctl generation functions. - Harden various metadata verifiers. - Fix various accounting problems. - Fix uncancelled transactions leaking when xattr functions fail. - Prevent the copy-on-write speculative preallocation garbage collector from racing with writeback. - Emit log reservation type information as trace data so that we can compare against xfsprogs. - Fix some erroneous asserts in the online scrub code. - Clean up the transaction reservation calculations. - Fix various minor bugs in online scrub. - Log complaints about mixed dio/buffered writes once per day and less noisily than before. - Refactor buffer log item lists to use list_head. - Break PNFS leases before reflinking blocks. - Reduce lock contention on reflink source files. - Fix some quota accounting problems with reflink. - Fix a serious corruption problem in the direct cow write code where we fed bad iomaps to the vfs iomap consumers. - Various other refactorings. - Remove EXPERIMENTAL tag from reflink!" * tag 'xfs-4.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (94 commits) xfs: remove experimental tag for reflinks xfs: don't screw up direct writes when freesp is fragmented xfs: check reflink allocation mappings iomap: warn on zero-length mappings xfs: treat CoW fork operations as delalloc for quota accounting xfs: only grab shared inode locks for source file during reflink xfs: allow xfs_lock_two_inodes to take different EXCL/SHARED modes xfs: reflink should break pnfs leases before sharing blocks xfs: don't clobber inobt/finobt cursors when xref with rmap xfs: skip CoW writes past EOF when writeback races with truncate xfs: preserve i_rdev when recycling a reclaimable inode xfs: refactor accounting updates out of xfs_bmap_btalloc xfs: refactor inode verifier corruption error printing xfs: make tracepoint inode number format consistent xfs: always zero di_flags2 when we free the inode xfs: call xfs_qm_dqattach before performing reflink operations xfs: bmap code cleanup Use list_head infra-structure for buffer's log items list Split buffer's b_fspriv field Get rid of xfs_buf_log_item_t typedef ...

Pull GFS2 updates from Bob Peterson: "We've got 30 patches for this merge window. These generally fall into five categories: - code cleanups - patches related to adding PUNCH_HOLE support to GFS2 - support for new fields in resource group headers - a few bug fixes - support for new fields in journal log headers. These new fields, which were previously unused, are designed to make it easier to track down file system corruption, and allow fsck.gfs2 to make more intelligent decisions when finding and fixing file system corruption. Details: - Two patches from Abhi Das, to trim the ordered writes list, which used to grow uncontrollably until unmount. - Several patches from Andreas Gruenbacher: remove an unused parameter from function gfs2_write_jdata_pagevec, remove a pointless BUG_ON, clean up an error patch in trunc_start, remove some unused parameters from truncate, make gfs2_journaled_truncate more efficient, clean up the support functions for truncate, fix metadata read-ahead for truncate to make it faster, fix up the non-recursive truncate code, rework and rename gfs2_block_truncate_page, generalize the non-recursive truncate code so it can take a range of values for punch_hole support, introduce new PUNCH_HOLE support that take advantage of the previous patches, add fallocate support with PUNCH_HOLE, fix some typos in the comments, add the function gfs2_max_stuffed_size to replace a piece of code that was needlessly repeated throughout GFS2, a minor cleanup to function gfs2_page_add_databufs, get rid of function gfs2_log_header_in in preparation for the new log header fields, and also fix up some missing newlines in kernel messages. - Andy Price added a new field to resource groups to indicate where the next one should be, to allow fsck.gfs2 to make better repairs. He also added new rindex fields for consistency checking, and added a crc field to resource group headers for consistency checking. - I reduced redundancy in functions common to freeing dinodes, and when writing log headers between the journalling code and journal recovery code. Also added new fields to journal log headers based on a prototype from Steve Whitehouse, and log the source of journal log headers so we can better track down journal corruption. Minor comment typo fix and a fix for a BUG in an unlink error path. - Steve Whitehouse contributed a patch to fix an incorrect use of the gfs2_blk2rgrpd function. - Tetsuo Handa contributed a patch that fixes incorrect error handling in function init_gfs2_fs" * tag 'gfs2-4.16.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: (30 commits) gfs2: Add a few missing newlines in messages gfs2: Remove inode from ordered write list in gfs2_write_inode() GFS2: Don't try to end a non-existent transaction in unlink GFS2: Fix minor comment typo GFS2: Log the reason for log flushes in every log header GFS2: Introduce new gfs2_log_header_v2 gfs2: Get rid of gfs2_log_header_in gfs2: Minor gfs2_page_add_databufs cleanup gfs2: Add gfs2_max_stuffed_size gfs2: Typo fixes gfs2: Implement fallocate(FALLOC_FL_PUNCH_HOLE) gfs2: Turn trunc_dealloc into punch_hole gfs2: Generalize truncate code Turn gfs2_block_truncate_page into gfs2_block_zero_range gfs2: Improve non-recursive delete algorithm gfs2: Fix metadata read-ahead during truncate gfs2: Clean up {lookup,fillup}_metapath gfs2: Remove minor gfs2_journaled_truncate inefficiencies gfs2: truncate: Remove unnecessary oldsize parameters gfs2: Clean up trunc_start error path ...

If devpts_ptmx_path() returns an error code, then devpts_mntget() dereferences an ERR_PTR(): BUG: unable to handle kernel paging request at fffffffffffffff5 IP: devpts_mntget+0x13f/0x280 fs/devpts/inode.c:173 Fix it by returning early in the error paths.

As Linus points out: The inode_cmp_iversion{+raw}() functions are pure and utter crap. Why? You say that they return 0/negative/positive, but they do so in a completely broken manner. They return that ternary value as the sequence number difference in a 's64', which means that if you actually care about that ternary value, and do the *sane* thing that the kernel-doc of the function implies is the right thing, you would do int cmp = inode_cmp_iversion(inode, old); if (cmp < 0 ... and as a result you get code that looks sane, but that doesn't actually *WORK* right. Since none of the callers actually care about the ternary value here, convert the inode_cmp_iversion{+raw} functions to just return a boolean value (false for matching, true for non-matching). This matches the existing use of these functions just fine, and makes it simple to convert them to return a ternary value in the future if we grow callers that need it. With this change we can also reimplement inode_cmp_iversion in a simpler way using inode_peek_iversion.
