      kbuild: explicitly run mksysmap as sed script from link-vmlinux.sh · 96c96566
      Richard Acayan authored 
      In commit b18b0470 ("kbuild: change scripts/mksysmap into sed
script"), the mksysmap script was transformed into a sed script,
made directly executable with "#!/bin/sed -f". Apparently, the path to
sed is different on NixOS.

The shebang can't use the env command, otherwise the "sed -f" command
would be treated as a single argument. This can be solved with the -S
flag, but that is a GNU extension. Explicitly use sed instead of relying
on the executable shebang to fix NixOS builds without breaking build
environments using Busybox.

Fixes: b18b0470 ("kbuild: change scripts/mksysmap into sed script")

      btrfs: protect folio::private when attaching extent buffer folios · f3a5367c
      Qu Wenruo authored 
      [BUG]
Since v6.8 there are rare kernel crashes reported by various people,
the common factor is bad page status error messages like this:

  page dumped because: non-NULL mapping

[CAUSE]
Commit 09e6cef1 ("btrfs: refactor alloc_extent_buffer() to
allocate-then-attach method") changes the sequence when allocating a new
extent buffer.

Previously we always called grab_extent_buffer() under
mapping->i_private_lock, to ensure the safety on modification on
folio::private (which is a pointer to extent buffer for regular
sectorsize).

This can lead to the following race:

Thread A is trying to allocate an extent buffer at bytenr X, with 4
4K pages, meanwhile thread B is trying to release the page at X + 4K
(the second page of the extent buffer at X).

           Thread A                |                 Thread B
-----------------------------------+-------------------------------------
                                   | btree_release_folio()
				   | | This is for the page at X + 4K,
				   | | Not page X.
				   | |
alloc_extent_buffer()              | |- release_extent_buffer()
|- filemap_add_folio() for the     | |  |- atomic_dec_and_test(eb->refs)
|  page at bytenr X (the first     | |  |
|  page).                          | |  |
|  Which returned -EEXIST.         | |  |
|                                  | |  |
|- filemap_lock_folio()            | |  |
|  Returned the first page locked. | |  |
|                                  | |  |
|- grab_extent_buffer()            | |  |
|  |- atomic_inc_not_zero()        | |  |
|  |  Returned false               | |  |
|  |- folio_detach_private()       | |  |- folio_detach_private() for X
|     |- folio_test_private()      | |     |- folio_test_private()
      |  Returned true             | |     |  Returned true
      |- folio_put()               |       |- folio_put()

Now there are two puts on the same folio at folio X, leading to refcount
underflow of the folio X, and eventually causing the BUG_ON() on the
page->mapping.

The condition is not that easy to hit:

- The release must be triggered for the middle page of an eb
  If the release is on the same first page of an eb, page lock would kick
  in and prevent the race.

- folio_detach_private() has a very small race window
  It's only between folio_test_private() and folio_clear_private().

That's exactly when mapping->i_private_lock is used to prevent such race,
and commit 09e6cef1 ("btrfs: refactor alloc_extent_buffer() to
allocate-then-attach method") screwed that up.

At that time, I thought the page lock would kick in as
filemap_release_folio() also requires the page to be locked, but forgot
the filemap_release_folio() only locks one page, not all pages of an
extent buffer.

[FIX]
Move all the code requiring i_private_lock into
attach_eb_folio_to_filemap(), so that everything is done with proper
lock protection.

Furthermore to prevent future problems, add an extra
lockdep_assert_locked() to ensure we're holding the proper lock.

To reproducer that is able to hit the race (takes a few minutes with
instrumented code inserting delays to alloc_extent_buffer()):

  #!/bin/sh
  drop_caches () {
	  while(true); do
		  echo 3 > /proc/sys/vm/drop_caches
		  echo 1 > /proc/sys/vm/compact_memory
	  done
  }

  run_tar () {
	  while(true); do
		  for x in `seq 1 80` ; do
			  tar cf /dev/zero /mnt > /dev/null &
		  done
		  wait
	  done
  }

  mkfs.btrfs -f -d single -m single /dev/vda
  mount -o noatime /dev/vda /mnt
  # create 200,000 files, 1K each
  ./simoop -n 200000 -E -f 1k /mnt
