      io_uring: use fget/fput consistently · 73363c26
      Jens Axboe authored
      Normally within a syscall it's fine to use fdget/fdput for grabbing a
      file from the file table, and it's fine within io_uring as well. We do
      that via io_uring_enter(2), io_uring_register(2), and then also for
      cancel which is invoked from the latter. io_uring cannot close its own
      file descriptors as that is explicitly rejected, and for the cancel
      side of things, the file itself is just used as a lookup cookie.
      
      However, it is more prudent to ensure that full references are always
      grabbed. For anything threaded, either explicitly in the application
      itself or through use of the io-wq worker threads, this is what happens
      anyway. Generalize it and use fget/fput throughout.
      
      Also see the below link for more details.

      io_uring: free io_buffer_list entries via RCU · 5cf4f52e
      Jens Axboe authored
      mmap_lock nests under uring_lock out of necessity, as we may be doing
      user copies with uring_lock held. However, for mmap of provided buffer
      rings, we attempt to grab uring_lock with mmap_lock already held from
      do_mmap(). This makes lockdep, rightfully, complain:

      From that mmap(2) path, we really just need to ensure that the buffer
      list doesn't go away from underneath us. For the lower indexed entries,
      they never go away until the ring is freed and we can always sanely
      reference those as long as the caller has a file reference. For the
      higher indexed ones in our xarray, we just need to ensure that the
      buffer list remains valid while we return the address of it.
      
      Free the higher indexed io_buffer_list entries via RCU. With that we can
      avoid needing ->uring_lock inside mmap(2), and simply hold the RCU read
      lock around the buffer list lookup and address check.
      
      To ensure that the arrayed lookup either returns a valid fully formulated
      entry via RCU lookup, add an 'is_ready' flag that we access with store
      and release memory ordering. This isn't needed for the xarray lookups,
      but doesn't hurt either. Since this isn't a fast path, retain it across
      both types. Similarly, for the allocated array inside the ctx, ensure
      we use the proper load/acquire as setup could in theory be running in
      parallel with mmap.
      
      While in there, add a few lockdep checks for documentation purposes.

      io_uring/kbuf: prune deferred locked cache when tearing down · 07d6063d
      Jens Axboe authored
      We used to just use our page list for final teardown, which would ensure
      that we got all the buffers, even the ones that were not on the normal
      cached list. But while moving to slab for the io_buffers, we know only
      prune this list, not the deferred locked list that we have. This can
      cause a leak of memory, if the workload ends up using the intermediate
      locked list.
      
      Fix this by always pruning both lists when tearing down.

      io_uring/kbuf: recycle freed mapped buffer ring entries · b10b73c1
      Jens Axboe authored
      Right now we stash any potentially mmap'ed provided ring buffer range
      for freeing at release time, regardless of when they get unregistered.
      Since we're keeping track of these ranges anyway, keep track of their
      registration state as well, and use that to recycle ranges when
      appropriate rather than always allocate new ones.
      
      The lookup is a basic scan of entries, checking for the best matching
      free entry.

      io_uring/kbuf: defer release of mapped buffer rings · c392cbec
      Jens Axboe authored
      If a provided buffer ring is setup with IOU_PBUF_RING_MMAP, then the
      kernel allocates the memory for it and the application is expected to
      mmap(2) this memory. However, io_uring uses remap_pfn_range() for this
      operation, so we cannot rely on normal munmap/release on freeing them
      for us.
      
      Stash an io_buf_free entry away for each of these, if any, and provide
      a helper to free them post ->release().

      io_uring: don't allow discontig pages for IORING_SETUP_NO_MMAP · 820d070f
      Jens Axboe authored
      io_sqes_map() is used rather than io_mem_alloc(), if the application
      passes in memory for mapping rather than have the kernel allocate it and
      then mmap(2) the ranges. This then calls __io_uaddr_map() to perform the
      page mapping and pinning, which checks if we end up with the same pages,
      if more than one page is mapped. But this check is incorrect and only
      checks if the first and last pages are the same, where it really should
      be checking if the mapped pages are contigous. This allows mapping a
      single normal page, or a huge page range.
      
      Down the line we can add support for remapping pages to be virtually
      contigous, which is really all that io_uring cares about.

      io_uring/fdinfo: remove need for sqpoll lock for thread/pid retrieval · a0d45c3f
      Jens Axboe authored
      A previous commit added a trylock for getting the SQPOLL thread info via
      fdinfo, but this introduced a regression where we often fail to get it if
      the thread is busy. For that case, we end up not printing the current CPU
      and PID info.
      
      Rather than rely on this lock, just print the pid we already stored in
      the io_sq_data struct, and ensure we update the current CPU every time
      we've slept or potentially rescheduled. The latter won't potentially be
      100% accurate, but that wasn't the case before either as the task can
      get migrated at any time unless it has been pinned at creation time.
      
      We retain keeping the io_sq_data dereference inside the ctx->uring_lock,
      as it has always been, as destruction of the thread and data happen below
      that. We could make this RCU safe, but there's little point in doing that.
      
      With this, we always print the last valid information we had, rather than
      have spurious outputs with missing information.

      Pull ceph updates from Ilya Dryomov:
      
       - support for idmapped mounts in CephFS (Christian Brauner, Alexander
         Mikhalitsyn).
      
         The series was originally developed by Christian and later picked up
         and brought over the finish line by Alexander, who also contributed
         an enabler on the MDS side (separate owner_{u,g}id fields on the
         wire).
      
         The required exports for mnt_idmap_{get,put}() in VFS have been acked
         by Christian and received no objection from Christoph.
      
       - a churny change in CephFS logging to include cluster and client
         identifiers in log and debug messages (Xiubo Li).
      
         This would help in scenarios with dozens of CephFS mounts on the same
         node which are getting increasingly common, especially in the
         Kubernetes world.
