      Pull vfs fix from Christian Brauner:
       "Beginning of the merge window we introduced the vfs{g,u}id_t types in
        b27c82e1 ("attr: port attribute changes to new types") and changed
        various codepaths over including chown_common().
      
        When userspace passes -1 for an ownership change the ownership fields
        in struct iattr stay uninitialized. Usually this is fine because any
        code making use of any fields in struct iattr must check the
        ->ia_valid field whether the value of interest has been initialized.
        That's true for all struct iattr passing code.
      
        However, over the course of the last year with more heavy use of KMSAN
        we found quite a few places that got this wrong. A recent one I fixed
        was 3cb6ee99 ("9p: only copy valid iattrs in 9P2000.L setattr
        implementation").
      
        But we also have LSM hooks. Actually we have two. The first one is
        security_inode_setattr() in notify_change() which does the right thing
        and passes the full struct iattr down to LSMs and thus LSMs can check
        whether it is initialized.
      
        But then we also have security_path_chown() which passes down a path
        argument and the target ownership as the filesystem would see it. For
        the latter we now generate the target values based on struct iattr and
        pass it down. However, when userspace passes -1 then struct iattr
        isn't initialized.
      
        This patch simply initializes ->ia_vfs{g,u}id with INVALID_VFS{G,U}ID
        so the hook continue to see invalid ownership when -1 is passed from
        userspace. The only LSM that cares about the actual values is Tomoyo.
      
        The vfs codepaths don't look at these fields without ->ia_valid being
        set so there's no harm in initializing ->ia_vfs{g,u}id. Arguably this
        is also safer since we can't end up copying valid ownership values
        when invalid ownership values should be passed.
      
        This only affects mainline. No kernel has been released with this and
        thus no backport is needed. The commit is thus marked with a Fixes:
        tag but annotated with "# mainline only" (I didn't quite remember what
        Greg said about how to tell stable autoselect to not bother with fixes
        for mainline only)"

      Takashi Iwai authored
      This reverts commit ff878b40.
      
      Unfortunately the recent fix seems bringing another regressions with
      PulseAudio / pipewire, at least for Steinberg and MOTU devices.
      
      As a temporary solution, do a straight revert.  The issue for Android
      will be revisited again later by another different fix (if any).

      open: always initialize ownership fields · f52d74b1
      Tetsuo Handa authored
      Beginning of the merge window we introduced the vfs{g,u}id_t types in
      b27c82e1 ("attr: port attribute changes to new types") and changed
      various codepaths over including chown_common().
      
      During that change we forgot to account for the case were the passed
      ownership value is -1. In this case the ownership fields in struct iattr
      aren't initialized but we rely on them being initialized by the time we
      generate the ownership to pass down to the LSMs. All the major LSMs
      don't care about the ownership values at all. Only Tomoyo uses them and
      so it took a while for syzbot to unearth this issue.
      
      Fix this by initializing the ownership fields and do it within the
      retry_deleg block. While notify_change() doesn't alter the ownership
      fields currently we shouldn't rely on it.
      
      Since no kernel has been released with these changes this does not
      needed to be backported to any stable kernels.

      ALSA: hda/hdmi: Fix the converter reuse for the silent stream · 5f80d6bd
      Jaroslav Kysela authored
      When the user space pcm stream uses the silent stream converter,
      it is no longer allocated for the silent stream. Clear the appropriate
      flag in the hdmi_pcm_open() function. The silent stream setup may
      be applied in hdmi_pcm_close() (and the error path - open fcn) again.
      
      If the flag is not cleared, the reuse conditions for the silent
      stream converter in hdmi_choose_cvt() may improperly share
      this converter.
