      io_uring: fix data race to avoid potential NULL-deref · b16ef427
      Marco Elver authored
      Commit ba5ef6dc ("io_uring: fortify tctx/io_wq cleanup") introduced
      setting tctx->io_wq to NULL a bit earlier. This has caused KCSAN to
      detect a data race between accesses to tctx->io_wq:
      
        write to 0xffff88811d8df330 of 8 bytes by task 3709 on cpu 1:
         io_uring_clean_tctx                  fs/io_uring.c:9042 [inline]
         __io_uring_cancel                    fs/io_uring.c:9136

         arch_do_signal_or_restart            arch/x86/kernel/signal.c:789
         handle_signal_work                   kernel/entry/common.c:147 [inline]
         exit_to_user_mode_loop               kernel/entry/common.c:171 [inline]
         ...
        read to 0xffff88811d8df330 of 8 bytes by task 6412 on cpu 0:
         io_uring_try_cancel_iowq             fs/io_uring.c:8911 [inline]
         io_uring_try_cancel_requests         fs/io_uring.c:8933
         io_ring_exit_work                    fs/io_uring.c:8736
         process_one_work                     kernel/workqueue.c:2276
         ...
      
      With the config used, KCSAN only reports data races with value changes:
      this implies that in the case here we also know that tctx->io_wq was
      non-NULL. Therefore, depending on interleaving, we may end up with:
      
                    [CPU 0]                 |        [CPU 1]
        io_uring_try_cancel_iowq()          | io_uring_clean_tctx()
          if (!tctx->io_wq) // false        |   ...
          ...                               |   tctx->io_wq = NULL
          io_wq_cancel_cb(tctx->io_wq, ...) |   ...
            -> NULL-deref                   |
      
      Note: It is likely that thus far we've gotten lucky and the compiler
      optimizes the double-read into a single read into a register -- but this
      is never guaranteed, and can easily change with a different config!
      
      Fix the data race by restoring the previous behaviour, where both
      setting io_wq to NULL and put of the wq are _serialized_ after
      concurrent io_uring_try_cancel_iowq() via acquisition of the uring_lock
      and removal of the node in io_uring_del_task_file().

      io-wq2:worker1     | waits bit1
      io-wq1:worker3     | waits bit1

      io-wq1:worker3     | be waked up, even though wqe is freed
      
      After all iou-wrk belonging to io-wq1 have exited, remove wqe
      form hash waitqueue, it is guaranteed that there will be no more
      wqe belonging to io-wq1 in the hash waitqueue.

      io_uring/io-wq: close io-wq full-stop gap · 17a91051
      Pavel Begunkov authored
      There is an old problem with io-wq cancellation where requests should be
      killed and are in io-wq but are not discoverable, e.g. in @next_hashed
      or @linked vars of io_worker_handle_work(). It adds some unreliability
      to individual request canellation, but also may potentially get
      __io_uring_cancel() stuck. For instance:
      
      1) An __io_uring_cancel()'s cancellation round have not found any
         request but there are some as desribed.
      2) __io_uring_cancel() goes to sleep
      3) Then workers wake up and try to execute those hidden requests
         that happen to be unbound.
      
      As we already cancel all requests of io-wq there, set IO_WQ_BIT_EXIT
      in advance, so preventing 3) from executing unbound requests. The
      workers will initially break looping because of getting a signal as they
      are threads of the dying/exec()'ing user task.

      io_uring: Fix premature return from loop and memory leak · cf3770e7
      Colin Ian King authored
      Currently the -EINVAL error return path is leaking memory allocated
      to data. Fix this by not returning immediately but instead setting
      the error return variable to -EINVAL and breaking out of the loop.

      io_uring: allow empty slots for reg buffers · 6224843d
      Pavel Begunkov authored
      Allow empty reg buffer slots any request using which should fail. This
      allows users to not register all buffers in advance, but do it lazily
      and/or on demand via updates. That is achieved by setting iov_base and
      iov_len to zero for registration and/or buffer updates. Empty buffer
      can't have a non-zero tag.
      
      Implementation details: to not add extra overhead to io_import_fixed(),
      create a dummy buffer crafted to fail any request using it, and set it
      to all empty buffer slots.

      io_uring: dont overlap internal and user req flags · dddca226
      Pavel Begunkov authored
      CQE flags take one byte that we store in req->flags together with other
      REQ_F_* internal flags. CQE flags are copied directly into req and then
      verified that requires some handling on failures, e.g. to make sure that
      that copy doesn't set some of the internal flags.
      
      Move all internal flags to take bits after the first byte, so we don't
      need extra handling and make it safer overall.

      Linus Torvalds authored
      Pull xfs updates from Darrick Wong:
       "The notable user-visible addition this cycle is ability to remove
        space from the last AG in a filesystem. This is the first of many
        changes needed for full-fledged support for shrinking a filesystem.
        Still needed are (a) the ability to reorganize files and metadata away
        from the end of the fs; (b) the ability to remove entire allocation
        groups; (c) shrink support for realtime volumes; and (d) thorough
        testing of (a-c).
      
        There are a number of performance improvements in this code drop: Dave
        streamlined various parts of the buffer logging code and reduced the
        cost of various debugging checks, and added the ability to pre-create
        the xattr structures while creating files. Brian eliminated
        transaction reservations that were being held across writeback (thus
        reducing livelock potential.
      
        Other random pieces: Pavel fixed the repetitve warnings about
        deprecated mount options, I fixed online fsck to behave itself when a
        readonly remount comes in during scrub, and refactored various other
        parts of that code, Christoph contributed a lot of refactoring this
        cycle. The xfs_icdinode structure has been absorbed into the (incore)
        xfs_inode structure, and the format and flags handling around
        xfs_inode_fork structures has been simplified. Chandan provided a
        number of fixes for extent count overflow related problems that have
        been shaken out by debugging knobs added during 5.12.
      
        Summary:
      
         - Various minor fixes in online scrub.
      
         - Prevent metadata files from being automatically inactivated.
      
         - Validate btree heights by the computed per-btree limits.
      
         - Don't warn about remounting with deprecated mount options.
      
         - Initialize attr forks at create time if we suspect we're going to
           need to store them.
      
         - Reduce memory reallocation workouts in the logging code.
      
         - Fix some theoretical math calculation errors in logged buffers that
           span multiple discontig memory ranges but contiguous ondisk
           regions.
      
         - Speedups in dirty buffer bitmap handling.
      
         - Make type verifier functions more inline-happy to reduce overhead.
      
         - Reduce debug overhead in directory checking code.
      
         - Many many typo fixes.
      
         - Begin to handle the permanent loss of the very end of a filesystem.
      
         - Fold struct xfs_icdinode into xfs_inode.
      
         - Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx
           ioctl.
      
         - Remove a broken directory block format check from online scrub.
      
         - Fix a bug where we could produce an unnecessarily tall data fork
           btree when creating an attr fork.
      
         - Fix scrub and readonly remounts racing.
      
         - Fix a writeback ioend log deadlock problem by dropping the behavior
           where we could preallocate a setfilesize transaction.
      
         - Fix some bugs in the new extent count checking code.
      
         - Fix some bugs in the attr fork preallocation code.

       "Here's a collection of largely clk driver updates. The usual suspects
        are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip,
        but it feels pretty light on commits.
      
        There's only one real commit to the framework core and that's to
        consolidate code. Otherwise the diffstat is dominated by many Qualcomm
        clk driver patches that modernize the driver for the proper way of
        speciying clk parents. That's shifting data around, which could subtly
        break things so I'll be on the lookout for fixes.
      
        New Drivers:
         - Proper clk driver for Mediatek MT7621 SoCs
         - Support for the clock controller on the new Rockchip rk3568
      
        Updates:
         - Simplify Zynq Kconfig dependencies
         - Use clk_hw pointers in socfpga driver
         - Cleanup parent data in qcom clk drivers
         - Some cleanups for rk3399 modularization
         - Fix reparenting of i.MX UART clocks by initializing only the ones
           associated to stdout
         - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
         - Make i.MX LPCG and SCU clocks return on registering failure
         - Kernel doc fixes
         - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N

      Pull io_uring updates from Jens Axboe:
      
       - Support for multi-shot mode for POLL requests
      
       - More efficient reference counting. This is shamelessly stolen from
         the mm side. Even though referencing is mostly single/dual user, the
         128 count was retained to keep the code the same. Maybe this
         should/could be made generic at some point.
      
       - Removal of the need to have a manager thread for each ring. The
         manager threads only job was checking and creating new io-threads as
         needed, instead we handle this from the queue path.
      
       - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this
         thread is "just" a regular application thread, so no need to restrict
         use of it anymore.
      
       - Cleanup of how internal async poll data lifetime is managed.
      
       - Fix for syzbot reported crash on SQPOLL cancelation.
      
       - Make buffer registration more like file registrations, which includes
         flexibility in avoiding full set unregistration and re-registration.
      
       - Fix for io-wq affinity setting.
      
       - Be a bit more defensive in task->pf_io_worker setup.
