commit 4c9a4bc8 upstream. In order to remove dropping rq->lock from the switched_{to,from}()/prio_changed() sched_class methods, run the balance callbacks after it. We need to remove dropping rq->lock because its buggy, suppose using sched_setattr()/sched_setscheduler() to change a running task from FIFO to OTHER. By the time we get to switched_from_rt() the task is already enqueued on the cfs runqueues. If switched_from_rt() does pull_rt_task() and drops rq->lock, load-balancing can come in and move our task @p to another rq. The subsequent switched_to_fair() still assumes @p is on @rq and bad things will happen. By using balance callbacks we delay the load-balancing operations {rt,dl}x{push,pull} until we've done all the important work and the task is fully set up. Furthermore, the balance callbacks do not know about @p, therefore they cannot get confused like this. Reported-by:

commit d6d86c0a upstream. Sasha Levin reported KASAN splash inside isolate_migratepages_range(). Problem is in the function __is_movable_balloon_page() which tests AS_BALLOON_MAP in page->mapping->flags. This function has no protection against anonymous pages. As result it tried to check address space flags inside struct anon_vma. Further investigation shows more problems in current implementation: * Special branch in __unmap_and_move() never works: balloon_page_movable() checks page flags and page_count. In __unmap_and_move() page is locked, reference counter is elevated, thus balloon_page_movable() always fails. As a result execution goes to the normal migration path. virtballoon_migratepage() returns MIGRATEPAGE_BALLOON_SUCCESS instead of MIGRATEPAGE_SUCCESS, move_to_new_page() thinks this is an error code and assigns newpage->mapping to NULL. Newly migrated page lose connectivity with balloon an all ability for further migration. * lru_lock erroneously required in isolate_migratepages_range() for isolation ballooned page. This function releases lru_lock periodically, this makes migration mostly impossible for some pages. * balloon_page_dequeue have a tight race with balloon_page_isolate: balloon_page_isolate could be executed in parallel with dequeue between picking page from list and locking page_lock. Race is rare because they use trylock_page() for locking. This patch fixes all of them. Instead of fake mapping with special flag this patch uses special state of page->_mapcount: PAGE_BALLOON_MAPCOUNT_VALUE = -256. Buddy allocator uses PAGE_BUDDY_MAPCOUNT_VALUE = -128 for similar purpose. Storing mark directly in struct page makes everything safer and easier. PagePrivate is used to mark pages present in page list (i.e. not isolated, like PageLRU for normal pages). It replaces special rules for reference counter and makes balloon migration similar to migration of normal pages. This flag is protected by page_lock together with link to the balloon device.

commit f436b2ac upstream. The Performance Monitors extension is an optional feature of the AArch64 architecture, therefore, in order to access Performance Monitors registers safely, the kernel should detect the architected PMU unit presence through the ID_AA64DFR0_EL1 register PMUVer field before accessing them. This patch implements a guard by reading the ID_AA64DFR0_EL1 register PMUVer field to detect the architected PMU presence and prevent accessing PMU system registers if the Performance Monitors extension is not implemented in the core.

commit 42cb14b1 upstream. clear_page_dirty_for_io() has accumulated writeback and memcg subtleties since v2.6.16 first introduced page migration; and the set_page_dirty() which completed its migration of PageDirty, later had to be moderated to __set_page_dirty_nobuffers(); then PageSwapBacked had to skip that too. No actual problems seen with this procedure recently, but if you look into what the clear_page_dirty_for_io(page)+set_page_dirty(newpage) is actually achieving, it turns out to be nothing more than moving the PageDirty flag, and its NR_FILE_DIRTY stat from one zone to another. It would be good to avoid a pile of irrelevant decrementations and incrementations, and improper event counting, and unnecessary descent of the radix_tree under tree_lock (to set the PAGECACHE_TAG_DIRTY which radix_tree_replace_slot() left in place anyway). Do the NR_FILE_DIRTY movement, like the other stats movements, while interrupts still disabled in migrate_page_move_mapping(); and don't even bother if the zone is the same. Do the PageDirty movement there under tree_lock too, where old page is frozen and newpage not yet visible: bearing in mind that as soon as newpage becomes visible in radix_tree, an un-page-locked set_page_dirty() might interfere (or perhaps that's just not possible: anything doing so should already hold an additional reference to the old page, preventing its migration; but play safe). But we do still need to transfer PageDirty in migrate_page_copy(), for those who don't go the mapping route through migrate_page_move_mapping(). Signed-off-by:

commit 23c8a812 upstream. This fixes CVE-2016-0758. In the ASN.1 decoder, when the length field of an ASN.1 value is extracted, it isn't validated against the remaining amount of data before being added to the cursor. With a sufficiently large size indicated, the check: datalen - dp < 2 may then fail due to integer overflow. Fix this by checking the length indicated against the amount of remaining data in both places a definite length is determined. Whilst we're at it, make the following changes: (1) Check the maximum size of extended length does not exceed the capacity of the variable it's being stored in (len) rather than the type that variable is assumed to be (size_t). (2) Compare the EOC tag to the symbolic constant ASN1_EOC rather than the integer 0. (3) To reduce confusion, move the initialisation of len outside of: for (len = 0; n > 0; n--) { since it doesn't have anything to do with the loop counter n. Signed-off-by:

commit 723cac48 upstream. Extent swap operations are another extent manipulation operation that we need to ensure does not race against mmap page faults. The current code returns if the file is mapped prior to the swap being done, but it could potentially race against new page faults while the swap is in progress. Hence we should use the XFS_MMAPLOCK_EXCL for this operation, too. While there, fix the error path handling that can result in double unlocks of the inodes when cancelling the swapext transaction.

commit 0f9160b4 upstream. Now that truncate locks out new page faults, we no longer need to do special writeback hacks in truncate to work around potential races between page faults, page cache truncation and file size updates to ensure we get write page faults for extending truncates on sub-page block size filesystems. Hence we can remove the code in xfs_setattr_size() that handles this and update the comments around the code tha thandles page cache truncate and size updates to reflect the new reality.

commit e8e9ad42 upstream. Now we have the i_mmap_lock being held across the page fault IO path, we now add extent manipulation operation exclusion by adding the lock to the paths that directly modify extent maps. This includes truncate, hole punching and other fallocate based operations. The operations will now take both the i_iolock and the i_mmaplock in exclusive mode, thereby ensuring that all IO and page faults block without holding any page locks while the extent manipulation is in progress. This gives us the lock order during truncate of i_iolock -> i_mmaplock -> page_lock -> i_lock, hence providing the same lock order as the iolock provides the normal IO path without involving the mmap_sem.

commit 653c60b6 upstream. Right now we cannot serialise mmap against truncate or hole punch sanely. ->page_mkwrite is not able to take locks that the read IO path normally takes (i.e. the inode iolock) because that could result in lock inversions (read - iolock - page fault - page_mkwrite - iolock) and so we cannot use an IO path lock to serialise page write faults against truncate operations. Instead, introduce a new lock that is used *only* in the ->page_mkwrite path that is the equivalent of the iolock. The lock ordering in a page fault is i_mmaplock -> page lock -> i_ilock, and so in truncate we can i_iolock -> i_mmaplock and so lock out new write faults during the process of truncation. Because i_mmap_lock is outside the page lock, we can hold it across all the same operations we hold the i_iolock for. The only difference is that we never hold the i_mmaplock in the normal IO path and so do not ever have the possibility that we can page fault inside it. Hence there are no recursion issues on the i_mmap_lock and so we can use it to serialise page fault IO against inode modification operations that affect the IO path. This patch introduces the i_mmaplock infrastructure, lockdep annotations and initialisation/destruction code. Use of the new lock will be in subsequent patches. Signed-off-by:

commit 81217683 upstream. xfs_swap_extents() holds the ilock over a call to filemap_write_and_wait(), which can then try to write data and take the ilock. That causes a self-deadlock. Fix the deadlock and clean up the code by separating the locking appropriately. Add a lockflags variable to track what locks we are holding as we gain and drop them and cleanup the error handling to always use "out_unlock" with the lockflags variable. Signed-off-by:

commit c25a1e06 upstream. Commit 702e5bc6 ("ocfs2: use generic posix ACL infrastructure") refactored code to use posix_acl_create. The problem with this function is that it is not mindful of the cluster wide inode lock making it unsuitable for use with ocfs2 inode creation with ACLs. For example, when used in ocfs2_mknod, this function can cause deadlock as follows. The parent dir inode lock is taken when calling posix_acl_create -> get_acl -> ocfs2_iop_get_acl which takes the inode lock again. This can cause deadlock if there is a blocked remote lock request waiting for the lock to be downconverted. And same deadlock happened in ocfs2_reflink. This fix is to revert back using ocfs2_init_acl. Fixes: 702e5bc6 ("ocfs2: use generic posix ACL infrastructure") Signed-off-by:

What happens is that the "current_op" gets modified and freed and parg is assigned to the new allocated argument. But after the call to collapse_tree(), parg is assigned again to the just freed "current_op", and this causes the tool to crash.
