      Pull SafeSetID update from Micah Morton:
       "Add additional LSM hooks for SafeSetID
      
        SafeSetID is capable of making allow/deny decisions for set*uid calls
        on a system, and we want to add similar functionality for set*gid
        calls.
      
        The work to do that is not yet complete, so probably won't make it in
        for v5.8, but we are looking to get this simple patch in for v5.8
        since we have it ready.
      
        We are planning on the rest of the work for extending the SafeSetID
        LSM being merged during the v5.9 merge window"

      security: Add LSM hooks to set*gid syscalls · 39030e13
      Thomas Cedeno authored
      The SafeSetID LSM uses the security_task_fix_setuid hook to filter
      set*uid() syscalls according to its configured security policy. In
      preparation for adding analagous support in the LSM for set*gid()
      syscalls, we add the requisite hook here. Tested by putting print
      statements in the security_task_fix_setgid hook and seeing them get hit
      during kernel boot.

      Pull btrfs updates from David Sterba:
       "This reverts the direct io port to iomap infrastructure of btrfs
        merged in the first pull request. We found problems in invalidate page
        that don't seem to be fixable as regressions or without changing iomap
        code that would not affect other filesystems.
      
        There are four reverts in total, but three of them are followup
        cleanups needed to revert a43a67a2 cleanly. The result is the
        buffer head based implementation of direct io.
      
        Reverts are not great, but under current circumstances I don't see
        better options"

      Revert "btrfs: switch to iomap_dio_rw() for dio" · 55e20bd1
      David Sterba authored
      This reverts commit a43a67a2.
      
      This patch reverts the main part of switching direct io implementation
      to iomap infrastructure. There's a problem in invalidate page that
      couldn't be solved as regression in this development cycle.
      
      The problem occurs when buffered and direct io are mixed, and the ranges
      overlap. Although this is not recommended, filesystems implement
      measures or fallbacks to make it somehow work. In this case, fallback to
      buffered IO would be an option for btrfs (this already happens when
      direct io is done on compressed data), but the change would be needed in
      the iomap code, bringing new semantics to other filesystems.
      
      Another problem arises when again the buffered and direct ios are mixed,
      invalidation fails, then -EIO is set on the mapping and fsync will fail,
      though there's no real error.
      
      There have been discussions how to fix that, but revert seems to be the
      least intrusive option.

      net: ethernet: ti: ale: fix allmulti for nu type ale · bc139119
      Grygorii Strashko authored
      On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
      unregistered mcast packets to pass.
      
      This happens, because ALE VLAN entries on these SoCs do not contain port
      masks for reg/unreg mcast packets, but instead store indexes of
      ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
      reg/unreg mcast packets.
      This path was missed by commit 9d1f6447 ("net: ethernet: ti: ale: fix
      seeing unreg mcast packets with promisc and allmulti disabled").
      
      Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

      The ALE parameters structure is created on stack, so it has to be reset
      before passing to cpsw_ale_create() to avoid garbage values.
