[PATCH 4/4] huegtlbfs: handle page fault/truncate races

by Mike Kravetz

A huegtlb page fault can race with page truncation. Make the code identifying and handling these races more robust. Page fault handling needs to back out pages added to page cache beyond file size (i_size). When backing out the page, take care to restore reserve map entries and counts as necessary. File truncation (remove_inode_hugepages) needs to handle page mapping changes before locking the page. This could happen if page was added to page cache and later backed out in fault processing.

[PATCH 3/4] hugetlbfs: use hinode_rwsem for pmd sharing synchronization

by Mike Kravetz

Commit c0d0381ade79 ("hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization") required changes to mm locking order that are hugetlb specific. Specifically, i_mmap_rwsem had to be taken before the page lock. This is not a big issue in hugetlb specific code, but becomes more problematic in the areas of page migration and memory failure where generic mm code had to deal with this change to lock ordering. An ugly routine 'hugetlb_page_mapping_lock_write' was added to help with these issues. Recently, Hugh Dickins diagnosed a migration BUG as caused by code introduced with hugetlb i_mmap_rwsem synchronization [1]. Subsequent discussion in that thread pointed out additional problems in the code. In the previous patch, a rw_semaphore (hinode_rwsem) was added to the hugetlbfs inode. Using hinode_rwsem instead of i_mmap_rwsem is actually a 'cleaner' approach to this problem as it can be inserted in the lock hierarchy where needed. And, there is no issue with other parts of the mm using this rw_semaphore. Change code to use hinode_rwsem instead of i_mmap_rwsem.

[PATCH 2/4] hugetlbfs: add hinode_rwsem to hugetlb specific inode

by Mike Kravetz

The hugetlb pmd sharing code needs additional synchronization. This is because sharing established via a call huge_pte_alloc, could be undone before control is returned to the caller. As a result, the returned value may be invalid. Ideally, i_mmap_rwsem would be used for this type of synchronization. However, previous attempts at using i_mmap_rwsem have failed. This is partly due to conflicts with the existing uses of i_mmap_rwsem that force a locking order not compatible with it's use for pmd sharing. Introduce a rwsem (hinode_rwsem) that resides in the hugetlb specific inode for the purpose of pmd sharing synchronization. This patch adds the semaphore to the inode and also provides routines for using the semaphore. To minimize performance impacts, the routines only acquire the semaphore if pmd sharing is possible. In addition, routines which can be used with lockdep to help ensure proper locking are also added. Use of the new semaphore and supporting routines will be provided in a later patch.

[PATCH 1/4] Revert hugetlbfs: Use i_mmap_rwsem to address page fault/truncate race

by Mike Kravetz

Commit 87bf91d39bb5 ("hugetlbfs: Use i_mmap_rwsem to address page fault/truncate race") was made possible because a prior commit c0d0381ade79 ("hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization") took i_mmap_rwsem in read mode during huge page faults. Using i_mmap_rwsem for pmd sharing synchronization has proven problematic and will be removed in later patches. As a result, the assumptions upon which this patch was based will no longer be true. This reverts commit 87bf91d39bb52b688fb411d668fbe7df278b29ae Fixes 7bf91d39bb5 ("hugetlbfs: Use i_mmap_rwsem to address page fault/truncate race") Cc: <stable(a)vger.kernel.org> Signed-off-by: Mike Kravetz <mike.kravetz(a)oracle.com> --- fs/hugetlbfs/inode.c | 28 ++++++++-------------------- mm/hugetlb.c | 23 ++++++++++++----------- 2 files changed, 20 insertions(+), 31 deletions(-) diff --git a/fs/hugetlbfs/inode.c b/fs/hugetlbfs/inode.c index b5c109703daa..c1057378dbf4 100644 --- a/fs/hugetlbfs/inode.c +++ b/fs/hugetlbfs/inode.c @@ -444,9 +444,10 @@ hugetlb_vmdelete_list(struct rb_root_cached *root, pgoff_t start, pgoff_t end) * In this case, we first scan the range and release found pages. * After releasing pages, hugetlb_unreserve_pages cleans up region/reserv * maps and global counts.
