The patch titled
mm: fix pagecache write deadlocks
has been removed from the -mm tree. Its filename was
mm-fix-pagecache-write-deadlocks.patch
This patch was dropped because it is obsolete
------------------------------------------------------
Subject: mm: fix pagecache write deadlocks
From: Andrew Morton <akpm@xxxxxxxx> and Nick Piggin <npiggin@xxxxxxx>
The idea is to modify the core write() code so that it won't take a
pagefault while holding a lock on the pagecache page. There are a number
of different deadlocks possible if we try to do such a thing:
1. generic_buffered_write
2. lock_page
3. prepare_write
4. unlock_page+vmtruncate
5. copy_from_user
6. mmap_sem(r)
7. handle_mm_fault
8. lock_page (filemap_nopage)
9. commit_write
1. unlock_page
b. sys_munmap / sys_mlock / others
c. mmap_sem(w)
d. make_pages_present
e. get_user_pages
f. handle_mm_fault
g. lock_page (filemap_nopage)
2,8 - recursive deadlock if page is same
2,8;2,8 - ABBA deadlock is page is different
2,6;c,g - ABBA deadlock if page is same
- Instead of copy_from_user(), use inc_preempt_count() and
copy_from_user_inatomic().
- If the copy_from_user_inatomic() hits a pagefault, it'll return a short
copy.
- if the page was not uptodate, we cannot commit the write, because the
uncopied bit could have uninitialised data. Commit zero length copy,
which should do the right thing (ie. not set the page uptodate).
- if the page was uptodate, commit the copied portion so we make some
progress.
- unlock_page()
- go back and try to fault the page in again, redo the lock_page,
prepare_write, copy_from_user_inatomic(), etc.
- Now we have a non uptodate page, and we keep faulting on a 2nd or later
iovec, this gives a deadlock, because fault_in_pages readable only faults
in the first iovec. To fix this situation, if we fault on a !uptodate page,
make the next iteration only attempt to copy a single iovec.
- This also showed up a number of buggy prepare_write / commit_write
implementations that were setting the page uptodate in the prepare_write
side: bad! this allows uninitialised data to be read. Fix these.
(also, rename maxlen to seglen, because it was confusing)
