         disabled because handling those in all possible cases is "essentially
         impossible"

      ext4: fix wrong return err in ext4_load_and_init_journal() · 9f2a1d9f
      Jason Yan authored
      The return value is wrong in ext4_load_and_init_journal(). The local
      variable 'err' need to be initialized before goto out. The original code
      in __ext4_fill_super() is fine because it has two return values 'ret'
      and 'err' and 'ret' is initialized as -EINVAL. After we factor out
      ext4_load_and_init_journal(), this code is broken. So fix it by directly
      returning -EINVAL in the error handler path.

      ext4: fix BUG_ON() when directory entry has invalid rec_len · 17a0bc9b

      When opened a symlink, link name is from 'inode->i_link', but it may be
      reset to a new value when revalidate the dentry. If some processes get the
      link name on the race scenario, then UAF will happen on link name.
      
      Fix this by implementing 'get_link' interface to duplicate the link name.

       "Dave and I had thought that this would be a very quiet cycle, but we
        thought wrong.
      
        At first there were the usual trickle of minor bugfixes, but then
        Zorro pulled -rc1 and noticed complaints about the stronger memcpy
        checks w.r.t. flex arrays.
      
        Analyzing how to fix that revealed a bunch of validation gaps in
        validating ondisk log items during recovery, and then a customer hit
        an infinite loop in the refcounting code on a corrupt filesystem.
      
        So. This largeish batch of fixes addresses all those problems, I hope.
      
        Summary:
      
         - Fix a UAF bug during log recovery
      
         - Fix memory leaks when mount fails
      
         - Detect corrupt bestfree information in a directory block
      
         - Fix incorrect return value type for the dax page fault handlers
      
         - Fix fortify complaints about memcpy of xfs log item objects
      
         - Strengthen inadequate validation of recovered log items
      
         - Fix incorrectly declared flex array in EFI log item structs
      
         - Log corrupt log items for debugging purposes
      
         - Fix infinite loop problems in the refcount code if the refcount
           btree node block keys are corrupt
      
         - Fix infinite loop problems in the refcount code if the refcount
           btree records suffer MSB bitflips
      
         - Add more sanity checking to continued defer ops to prevent
           overflows from one AG to the next or off EOFS"

      Pull clk fixes from Stephen Boyd:
       "Fixes in clk drivers and some clk rate range fixes in the core as
        well:
      
         - Make sure the struct clk_rate_request is more sane
      
         - Remove a WARN_ON that was triggering for clks with no parents that
           can change frequency
      
         - Fix bad i2c bus transactions on Renesas rs9
      
         - Actually return an error in clk_mt8195_topck_probe() on an error
           path
      
         - Keep the GPU memories powered while the clk isn't enabled on
           Qualcomm's sc7280 SoC
      
         - Fix the parent clk for HSCIF modules on Renesas' R-Car V4H SoC"

      tracing: kprobe: Fix memory leak in test_gen_kprobe/kretprobe_cmd() · 66f0919c
      Shang XiaoJing authored
      test_gen_kprobe_cmd() only free buf in fail path, hence buf will leak
      when there is no failure. Move kfree(buf) from fail path to common path
      to prevent the memleak. The same reason and solution in
      test_gen_kretprobe_cmd().
