      afs: Fix infinite loop found by xfstest generic/676 · 17eabd42
      David Howells authored
      In AFS, a directory is handled as a file that the client downloads and
      parses locally for the purposes of performing lookup and getdents
      operations.  The in-kernel afs filesystem has a number of functions that
      do this.
      
      A directory file is arranged as a series of 2K blocks divided into
      32-byte slots, where a directory entry occupies one or more slots, plus
      each block starts with one or more metadata blocks.
      
      When parsing a block, if the last slots are occupied by a dirent that
      occupies more than a single slot and the file position points at a slot
      that's not the initial one, the logic in afs_dir_iterate_block() that
      skips over it won't advance the file pointer to the end of it.  This
      will cause an infinite loop in getdents() as it will keep retrying that
      block and failing to advance beyond the final entry.
      
      Fix this by advancing the file pointer if the next entry will be beyond
      it when we skip a block.
      
      This was found by the generic/676 xfstest but can also be triggered with
      something like:
      
      	~/xfstests-dev/src/t_readdir_3 /xfstest.test/z 4000 1

        It introduces support for controlling the audio DSP on Qualcomm
        MSM8226, as well as audio and compute DSPs on Qualcomm SC8280XP.
      
        It makes it possible to specify the firmware path for Mediatek's
        remote processors, fixes a double free in the SCP driver and addresses
        an issue with the SRAM initialization on MT8195.

      Linus Torvalds authored
      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've refactored the existing atomic write support
        implemented by in-memory operations to have storing data in disk
        temporarily, which can give us a benefit to accept more atomic writes.
      
        At the same time, we removed the existing volatile write support.
      
        We've also revisited the file pinning and GC flows and found some
        corner cases which contributeed abnormal system behaviours.
      
        As usual, there're several minor code refactoring for readability,
        sanity check, and clean ups.
      
        Enhancements:
      
         - allow compression for mmap files in compress_mode=user
      
         - kill volatile write support
      
         - change the current atomic write way
      
         - give priority to select unpinned section for foreground GC
      
         - introduce data read/write showing path info
      
         - remove unnecessary f2fs_lock_op in f2fs_new_inode
      
        Bug fixes:
      
         - fix the file pinning flow during checkpoint=disable and GCs
      
         - fix foreground and background GCs to select the right victims and
           get free sections on time
      
         - fix GC flags on defragmenting pages
      
         - avoid an infinite loop to flush node pages

      commit 233c1e6c319c ("kexec_file: drop weak attribute from

      This currently happens in next-20220527.
      
      Prepare the RISC-V similar to the s390 adaption done in 233c1e6c319c.

      video: fbdev: omap: Add prototype for hwa742_update_window_async() · 79b66128
      Helge Deller authored
      The symbol hwa742_update_window_async() is exported, but there is no
      prototype defined for it. That's why gcc complains:
      
      drivers-video-fbdev-omap-hwa742.c:warning:no-previous-prototype-for-hwa742_update_window_async
      
      Add the prototype, but I wonder if we couldn't drop exporting the symbol
      instead. Since omapfb_update_window_async() is exported the same way,
      are there any users outside of the tree?
