      selftests: vDSO: add --cflags for pkg-config command querying libsodium · 1e661b34
      Xi Ruoyao authored 
      When libsodium is installed into its own prefix, the --cflags output is
needed for the compiler to find libsodium headers.

      selftests: vDSO: look for arch-specific function name in getrandom test · e1bbcab4
      Christophe Leroy authored 
      Don't hard-code x86 specific names. Rather, use vdso_config definitions
to find the correct function matching the architecture.

Add random VDSO function names in names[][]. Remove the #ifdef
CONFIG_VDSO32, as having the name there all the time is harmless and
guaranties a steady index for following strings.

This is due to kernel include/linux/limits.h being included instead of
libc's limits.h.

This is because directory include/ is added through option -isystem so
it goes prior to glibc's include directory.

Replace -isystem by -idirafter.

But this implies that now tools/include/linux/linkage.h is included
instead of include/linux/linkage.h, so define a stub for
SYM_FUNC_START() and SYM_FUNC_END().

      selftests: vDSO: don't hard-code location of vDSO sources · 20a9af05

Don't hard-code vdso sources location in selftest Makefile. Instead
create a vdso/ symbolic link in tools/arch/$arch/ and update Makefile
accordingly.

      selftests: vDSO: simplify getrandom thread local storage and structs · 01b52f01
      Jason A. Donenfeld authored 
      Rather than using pthread_get/set_specific, just use gcc's __thread
annotation, which is noticeably faster and makes the code more obvious.

Also, just have one simplified struct called vgrnd, instead of trying to
split things up semantically. Those divisions were useful when this code
was split across several commit *messages*, but doesn't make as much
sense within a single file. This should make the code more clear and
provide a better example for implementers.

      Pull random number generator fix from Jason Donenfeld:
 "Reject invalid flags passed to vgetrandom() in the same way that
  getrandom() does, so that the behavior is the same, from Yann.

  The flags argument to getrandom() only has a behavioral effect on the
  function if the RNG isn't initialized yet, so vgetrandom() falls back
  to the syscall in that case. But if the RNG is initialized, all of the
  flags behave the same way, so vgetrandom() didn't bother checking
  them, and just ignored them entirely.

  But that doesn't account for invalid flags passed in, which need to be
  rejected so we can use them later"

CONFIG_TCG_TPM2_HMAC. When this option is enabled on ppc64 then the
following message appears in the kernel log due to a missing call to
tpm2_sessions_init().

      btrfs: fix uninitialized return value from btrfs_reclaim_sweep() · ecb54277
      Filipe Manana authored 
      The return variable 'ret' at btrfs_reclaim_sweep() is never assigned if
none of the space infos is reclaimable (for example if periodic reclaim
is disabled, which is the default), so we return an undefined value.

This can be fixed my making btrfs_reclaim_sweep() not return any value
as well as do_reclaim_sweep() because:

1) do_reclaim_sweep() always returns 0, so we can make it return void;

2) The only caller of btrfs_reclaim_sweep() (btrfs_reclaim_bgs()) doesn't
   care about its return value, and in its context there's nothing to do
   about any errors anyway.

Therefore remove the return value from btrfs_reclaim_sweep() and
do_reclaim_sweep().

  netfs:

   - Revert the removal of PG_private_2 from netfs_release_folio() as

   - When AS_RELEASE_ALWAYS is set on a mapping the folio needs to
     always be invalidated during truncation

   - Fix losing untruncated data in a folio by making letting
     netfs_release_folio() return false if the folio is dirty

   - Fix trimming of streaming-write folios in netfs_inval_folio()

   - Reset iterator before retrying a short read

   - Fix interaction of streaming writes with zero-point tracker

  afs:

   - During truncation afs currently calls truncate_setsize() which sets
     i_size, expands the pagecache and truncates it. The first two
     operations aren't needed because they will have already been done.
     So call truncate_pagecache() instead and skip the redundant parts

  overlayfs:

   - Fix checking of the number of allowed lower layers so 500 layers
     can actually be used instead of just 499

   - Add missing '\n' to pr_err() output

   - Pass string to ovl_parse_layer() and thus allow it to be used for
     Opt_lowerdir as well

  pidfd:

   - Revert blocking the creation of pidfds for kthread as apparently
     userspace relies on this. Specifically, it breaks systemd during
     shutdown
