      JFS: more checks for invalid superblock · 3bef198f
      Randy Dunlap authored
      syzbot is feeding invalid superblock data to JFS for mount testing.
      JFS does not check several of the fields -- just assumes that they
      are good since the JFS_MAGIC and version fields are good.
      
      In this case (syzbot reproducer), we have s_l2bsize == 0xda0c,
      pad == 0xf045, and s_state == 0x50, all of which are invalid IMO.
      Having s_l2bsize == 0xda0c causes this UBSAN warning:
        UBSAN: shift-out-of-bounds in fs/jfs/jfs_mount.c:373:25
        shift exponent -9716 is negative
      
      s_l2bsize can be tested for correctness. pad can be tested for non-0
      and punted. s_state can be tested for its valid values and punted.
      
      Do those 3 tests and if any of them fails, report the superblock as
      invalid/corrupt and let fsck handle it.
      
      With this patch, chkSuper() says this when JFS_DEBUG is enabled:
        jfs_mount: Mount Failure: superblock is corrupt!
        Mount JFS Failure: -22
        jfs_mount failed w/return code = -22
      
      The obvious problem with this method is that next week there could
      be another syzbot test that uses different fields for invalid values,
      this making this like a game of whack-a-mole.

      Linus Torvalds authored
      Pull xfs updates from Darrick Wong:
       "In this release we add the ability to set a 'needsrepair' flag
        indicating that we /know/ the filesystem requires xfs_repair, but
        other than that, it's the usual strengthening of metadata validation
        and miscellaneous cleanups.
      
        Summary:
      
         - Introduce a "needsrepair" "feature" to flag a filesystem as needing
           a pass through xfs_repair. This is key to enabling filesystem
           upgrades (in xfs_db) that require xfs_repair to make minor
           adjustments to metadata.
      
         - Refactor parameter checking of recovered log intent items so that
           we actually use the same validation code as them that generate the
           intent items.
      
         - Various fixes to online scrub not reacting correctly to directory
           entries pointing to inodes that cannot be igetted.
      
         - Refactor validation helpers for data and rt volume extents.
      
         - Refactor XFS_TRANS_DQ_DIRTY out of existence.
      
         - Fix a longstanding bug where mounting with "uqnoenforce" would
           start user quotas in non-enforcing mode but /proc/mounts would
           display "usrquota", implying that they are being enforced.
      
         - Don't flag dax+reflink inodes as corruption since that is a valid
           (but not fully functional) combination right now.
      
         - Clean up raid stripe validation functions.
      
         - Refactor the inode allocation code to be more straightforward.
      
         - Small prep cleanup for idmapping support.
      
         - Get rid of the xfs_buf_t typedef"

        I'm being a bit conservative on the cutoff for this round due to the
        timing, so this is all the new development I'm going to take for this
        cycle (even if some of it probably normally would have been OK). There

        (PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of
        the .text.init alignment patch.
      
        With any luck we'll sort out the issue, but given how many bugs get
        fixed all over the place and how unrelated those features seem my
        guess is that we're just running into something that's been lurking
        for a while and has already been fixed in the newer QEMU (though I
        wouldn't be surprised if it's one of these implicit assumptions we
        have in the boot flow). If it was hardware I'd be strongly inclined to

      drm/i915: Fix mismatch between misplaced vma check and vma insert · 0e53656a
      Chris Wilson authored
      When inserting a VMA, we restrict the placement to the low 4G unless the
      caller opts into using the full range. This was done to allow usersapce
      the opportunity to transition slowly from a 32b address space, and to
      avoid breaking inherent 32b assumptions of some commands.
      
      However, for insert we limited ourselves to 4G-4K, but on verification
      we allowed the full 4G. This causes some attempts to bind a new buffer
      to sporadically fail with -ENOSPC, but at other times be bound
      successfully.
      
      commit 48ea1e32 ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1
      page") suggests that there is a genuine problem with stateless addressing
      that cannot utilize the last page in 4G and so we purposefully excluded
      it. This means that the quick pin pass may cause us to utilize a buggy
      placement.

      We now use ilk_hpd_irq_setup for all GMCH platforms that do not have
      hotplug. These are early gen3 and gen2 devices that now explode on boot
      as they try to access non-existent registers.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of the GPIO changes for the v5.11 kernel cycle:
      
        Core changes:
      
         - Retired the old set-up function for GPIO IRQ chips. All chips now
           use the template struct gpio_irq_chip and pass that to the core to
           be set up alongside the gpio_chip. We can finally get rid of the
           old cruft.
      
         - Some refactoring and clean up of the core code.
      
         - Support edge event timestamps to be stamped using REALTIME (wall
           clock) timestamps. We have found solid use cases for this, so we
           support it.
      
        New drivers:
      
         - MStar MSC313 GPIO driver.
      
         - HiSilicon GPIO driver.
      
        Driver improvements:
      
         - The PCA953x driver now also supports the NXP PCAL9554B/C chips.
      
         - The mockup driver can now be probed from the device tree which is
           pretty useful for virtual prototyping of devices.
      
         - The Rcar driver now supports .get_multiple()
      
         - The MXC driver dropped some legacy and became a pure device tree
           client.
      
         - The Exar driver was moved over to the IDA interface for
           enumerating, and also switched over to using regmap for register
           access"

        This series also includes addition of support for the SMB3 witness
        protocol which can provide important notifications from the server to
        client on server address or export or network changes. This can be
        useful for example in order to be notified before the failure - when a

        server notifications of when a share is moved).

      Pull tracing updates from Steven Rostedt:
       "The major update to this release is that there's a new arch config
        option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS.
      
        Currently, only x86_64 enables it. All the ftrace callbacks now take a
        struct ftrace_regs instead of a struct pt_regs. If the architecture
        has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will
        have enough information to read the arguments of the function being
        traced, as well as access to the stack pointer.
      
        This way, if a user (like live kernel patching) only cares about the
        arguments, then it can avoid using the heavier weight "regs" callback,
        that puts in enough information in the struct ftrace_regs to simulate
        a breakpoint exception (needed for kprobes).
      
        A new config option that audits the timestamps of the ftrace ring
        buffer at most every event recorded.
      
        Ftrace recursion protection has been cleaned up to move the protection
        to the callback itself (this saves on an extra function call for those
        callbacks).
      
        Perf now handles its own RCU protection and does not depend on ftrace
        to do it for it (saving on that extra function call).
      
        New debug option to add "recursed_functions" file to tracefs that
        lists all the places that triggered the recursion protection of the
        function tracer. This will show where things need to be fixed as
        recursion slows down the function tracer.
      
        The eval enum mapping updates done at boot up are now offloaded to a
        work queue, as it caused a noticeable pause on slow embedded boards.

      Pull modules updates from Jessica Yu:
       "Summary of modules changes for the 5.11 merge window:
      
         - Fix a race condition between systemd/udev and the module loader.
      
           The module loader was sending a uevent before the module was fully
           initialized (i.e., before its init function has been called). This
           means udev can start processing the module uevent before the module
           has finished initializing, and some udev rules expect that the
           module has initialized already upon receiving the uevent.
      
           This resulted in some systemd mount units failing if udev processes
           the event faster than the module can finish init. This is fixed by
           delaying the uevent until after the module has called its init
           routine.
      
         - Make the linker array sections for kernel params and module version
           attributes more robust by switching to use the alignment of the
           type in question.
      
           Namely, linker section arrays will be constructed using the
           alignment required by the struct (using __alignof__()) as opposed
           to a specific value such as sizeof(void *) or sizeof(long). This is
           less likely to cause breakages should the size of the type ever
           change (Johan Hovold)
      
         - Fix module state inconsistency by setting it back to GOING when a
           module fails to load and is on its way out (Miroslav Benes)
      
         - Some comment and code cleanups (Sergey Shtylyov)"
      
      * tag 'modules-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux:

      Pull overlayfs updates from Miklos Szeredi:
      
       - Allow unprivileged mounting in a user namespace.
      
         For quite some time the security model of overlayfs has been that
         operations on underlying layers shall be performed with the
         privileges of the mounting task.
      
         This way an unprvileged user cannot gain privileges by the act of
         mounting an overlayfs instance. A full audit of all function calls
         made by the overlayfs code has been performed to see whether they
         conform to this model, and this branch contains some fixes in this
         regard.

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've made more work into per-file compression support.
      
        For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
        change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
        DECOMPRESS_FILE provides a way to compress and decompress the existing
        normal files manually.
      
        There is also a new mount option, compress_mode=fs|user, which can
        control who compresses the data.
      
        Chao also added a checksum feature with a mount option so that
        we are able to detect any corrupted cluster.
      
        In addition, Daniel contributed casefolding with encryption patch,
        which will be used for Android devices.
      
        Summary:
      
        Enhancements:
         - add ioctls and mount option to manage per-file compression feature
         - support casefolding with encryption
         - support checksum for compressed cluster
         - avoid IO starvation by replacing mutex with rwsem
         - add sysfs, max_io_bytes, to control max bio size

         - fix use-after-free issue when compression and fsverity are enabled
         - fix consistency corruption during fault injection test
         - fix data offset for lseek

      nfp: move indirect block cleanup to flower app stop callback · 5b33afee
      Simon Horman authored
      The indirect block cleanup may cause control messages to be sent
      if offloaded flows are present. However, by the time the flower app
      cleanup callback is called txbufs are no longer available and attempts
      to send control messages result in a NULL-pointer dereference in
      nfp_ctrl_tx_one().
      
      This problem may be resolved by moving the indirect block cleanup
      to the stop callback, where txbufs are still available.
      
      As suggested by Jakub Kicinski and Louis Peens.

      octeontx2-af: Fix undetected unmap PF error check · d8a4ea35
      Colin Ian King authored
      Currently the check for an unmap PF error is always going to be false
      because intr_val is a 32 bit int and is being bit-mask checked against
      1ULL << 32.  Fix this by making intr_val a u64 to match the type at it
      is copied from, namely npa_event_context->npa_af_rvu_ge.
