dm writecache: remove BUG() and fail gracefully instead
Building on arch/s390/ results in this build error:
cc1: some warnings being treated as errors
../drivers/md/dm-writecache.c: In function 'persistent_memory_claim':
../drivers/md/dm-writecache.c:323:1: error: no return statement in function returning non-void [-Werror=return-type]
Fix this by replacing the BUG() with an -EOPNOTSUPP return.

dm table: Remove BUG_ON(in_interrupt())
The BUG_ON(in_interrupt()) in dm_table_event() is a historic leftover from a rework of the dm table code which changed the calling context. Issuing a BUG for a wrong calling context is frowned upon and in_interrupt() is deprecated and only covering parts of the wrong contexts. The sanity check for the context is covered by CONFIG_DEBUG_ATOMIC_SLEEP and other debug facilities already.

dm: fix bug with RCU locking in dm_blk_report_zones
The dm_get_live_table() function makes RCU read lock so
dm_put_live_table() must be called even if dm_table map is not found.

kvm: mmu: fix is_tdp_mmu_check when the TDP MMU is not in use
In some cases where shadow paging is in use, the root page will be either mmu->pae_root or vcpu->arch.mmu->lm_root. Then it will not have an associated struct kvm_mmu_page, because it is allocated with alloc_page instead of kvm_mmu_alloc_page. Just return false quickly from is_tdp_mmu_root if the TDP MMU is not in use, which also includes the case where shadow paging is enabled. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

afs: Fix afs_write_end() when called with copied == 0 [ver #3]
When afs_write_end() is called with copied == 0, it tries to set the
dirty region, but there's no way to actually encode a 0-length region in
the encoding in page->private.
"0,0", for example, indicates a 1-byte region at offset 0. The maths
miscalculates this and sets it incorrectly.
Fix it to just do nothing but unlock and put the page in this case. We
don't actually need to mark the page dirty as nothing presumably
changed.

ocfs2: initialize ip_next_orphan
Though problem if found on a lower 4.1.12 kernel, I think upstream has same issue. In one node in the cluster, there is the following callback trace: # cat /proc/21473/stack __ocfs2_cluster_lock.isra.36+0x336/0x9e0 [ocfs2] ocfs2_inode_lock_full_nested+0x121/0x520 [ocfs2] ocfs2_evict_inode+0x152/0x820 [ocfs2] evict+0xae/0x1a0 iput+0x1c6/0x230 ocfs2_orphan_filldir+0x5d/0x100 [ocfs2] ocfs2_dir_foreach_blk+0x490/0x4f0 [ocfs2] ocfs2_dir_foreach+0x29/0x30 [ocfs2] ocfs2_recover_orphans+0x1b6/0x9a0 [ocfs2] ocfs2_complete_recovery+0x1de/0x5c0 [ocfs2] process_one_work+0x169/0x4a0 worker_thread+0x5b/0x560 kthread+0xcb/0xf0 ret_from_fork+0x61/0x90 The above stack is not reasonable, the final iput shouldn't happen in ocfs2_orphan_filldir() function. Looking at the code, 2067 /* Skip inodes which are already added to recover list, since dio may 2068 * happen concurrently with unlink/rename */ 2069 if (OCFS2_I(iter)->ip_next_orphan) { 2070 iput(iter); 2071 return 0; 2072 } 2073 The logic thinks the inode is already in recover list on seeing ip_next_orphan is non-NULL, so it skip this inode after dropping a reference which incremented in ocfs2_iget(). While, if the inode is already in recover list, it should have another reference and the iput() at line 2070 should not be the final iput (dropping the last reference). So I don't think the inode is really in the recover list (no vmcore to confirm). Note that ocfs2_queue_orphans(), though not shown up in the call back trace, is holding cluster lock on the orphan directory when looking up for unlinked inodes. The on disk inode eviction could involve a lot of IOs which may need long time to finish. That means this node could hold the cluster lock for very long time, that can lead to the lock requests (from other nodes) to the orhpan directory hang for long time. Looking at more on ip_next_orphan, I found it's not initialized when allocating a new ocfs2_inode_info structure. This causes te reflink operations from some nodes hang for very long time waiting for the cluster lock on the orphan directory. Fix: initialize ip_next_orphan as NULL.

hugetlbfs: fix anon huge page migration race

entry_SYSCALL_64_after_hwframe+0x44/0xa9
Hugh Dickins diagnosed this as a migration bug caused by code introduced
to use i_mmap_rwsem for pmd sharing synchronization. Specifically, the
routine unmap_and_move_huge_page() is always passing the TTU_RMAP_LOCKED
flag to try_to_unmap() while holding i_mmap_rwsem. This is wrong for
anon pages as the anon_vma_lock should be held in this case. Further
analysis suggested that i_mmap_rwsem was not required to he held at all
when calling try_to_unmap for anon pages as an anon page could never be
part of a shared pmd mapping.
Discussion also revealed that the hack in hugetlb_page_mapping_lock_write
to drop page lock and acquire i_mmap_rwsem is wrong. There is no way to
keep mapping valid while dropping page lock.
This patch does the following:
- Do not take i_mmap_rwsem and set TTU_RMAP_LOCKED for anon pages when
calling try_to_unmap.
- Remove the hacky code in hugetlb_page_mapping_lock_write. The routine
will now simply do a 'trylock' while still holding the page lock. If
the trylock fails, it will return NULL. This could impact the
callers:
- migration calling code will receive -EAGAIN and retry up to the
hard coded limit (10).
- memory error code will treat the page as BUSY. This will force
killing (SIGKILL) instead of SIGBUS any mapping tasks.
Do note that this change in behavior only happens when there is a
race. None of the standard kernel testing suites actually hit this
race, but it is possible.

mm/gup: use unpin_user_pages() in __gup_longterm_locked()
When FOLL_PIN is passed to __get_user_pages() the page list must be put
back using unpin_user_pages() otherwise the page pin reference persists
in a corrupted state.
There are two places in the unwind of __gup_longterm_locked() that put
the pages back without checking. Normally on error this function would
return the partial page list making this the caller's responsibility,
but in these two cases the caller is not allowed to see these pages at
all.

Thus checking for the page pointer is required too. The cache flush is done through an inter processor interrupt when a piece of memory is off-lined. That interrupt is triggered when a memory hot-unplug operation is initiated and offline_pages() is calling the slub's MEM_GOING_OFFLINE callback slab_mem_going_offline_callback() which is calling flush_cpu_slab(). If that interrupt is caught between the reading of c->freelist and the reading of c->page, this could lead to such a situation. That situation is expected and the later call to this_cpu_cmpxchg_double() will detect the change to c->freelist and redo the whole operation. In commit |

mm/compaction: stop isolation if too many pages are isolated and we have pages to migrate
In isolate_migratepages_block, if we have too many isolated pages and
nr_migratepages is not zero, we should try to migrate what we have
without wasting time on isolating.
In theory it's possible that multiple parallel compactions will cause
too_many_isolated() to become true even if each has isolated less than
COMPACT_CLUSTER_MAX, and loop forever in the while loop. Bailing
immediately prevents that.

mm/compaction: count pages and stop correctly during page isolation
In isolate_migratepages_block, when cc->alloc_contig is true, we are
able to isolate compound pages. But nr_migratepages and nr_isolated did
not count compound pages correctly, causing us to isolate more pages
than we thought.
So count compound pages as the number of base pages they contain.
Otherwise, we might be trapped in too_many_isolated while loop, since
the actual isolated pages can go up to COMPACT_CLUSTER_MAX*512=16384,
where COMPACT_CLUSTER_MAX is 32, since we stop isolation after
cc->nr_migratepages reaches to COMPACT_CLUSTER_MAX.
In addition, after we fix the issue above, cc->nr_migratepages could
never be equal to COMPACT_CLUSTER_MAX if compound pages are isolated,
thus page isolation could not stop as we intended. Change the isolation
stop condition to '>='.
The issue can be triggered as follows:
In a system with 16GB memory and an 8GB CMA region reserved by
hugetlb_cma, if we first allocate 10GB THPs and mlock them (so some THPs
are allocated in the CMA region and mlocked), reserving 6 1GB hugetlb
pages via /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages will
get stuck (looping in too_many_isolated function) until we kill either
task. With the patch applied, oom will kill the application with 10GB
THPs and let hugetlb page reservation finish.

drm/nouveau/ttm: avoid using nouveau_drm.ttm.type_vram prior to nv50
Pre-NV50 chipsets don't currently use the MMU subsystem that later
chipsets use, and type_vram is negative here, leading to an OOB memory
access.
This was previously guarded by a chipset check, restore that.

A very long time ago, a hack was added to the vfs fs freeze protection code to work around lockdep complaints about XFS, which would try to run a transaction (which requires intwrite protection) to finalize an xfs freeze (by which time the vfs had already taken intwrite). Fast forward a few years, and XFS fixed the recursive intwrite problem on its own, and the hack became unnecessary. Fast forward almost a decade, and latent bugs in the code converting this hack from freeze flags to freeze locks combine with lockdep bugs to make this reproduce frequently enough to notice page faults racing with freeze. Since the hack is unnecessary and causes thread race errors, just get rid of it completely. Making this kind of vfs change midway through a cycle makes me nervous, but a large enough number of the usual VFS/ext4/XFS/btrfs suspects have said this looks good and solves a real problem vector. And once that removal is done, __sb_start_write is now simple enough that it becomes possible to refactor the function into smaller, simpler static inline helpers in linux/fs.h. The cleanup is straightforward. Summary: - Finally remove the "convert to trylock" weirdness in the fs freezer code. It was necessary 10 years ago to deal with nested transactions in XFS, but we've long since removed that; and now this is causing subtle race conditions when lockdep goes offline and sb_start_* aren't prepared to retry a trylock failure. - Minor cleanups of the sb_start_* fs freeze helpers" * tag 'vfs-5.10-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: vfs: move __sb_{start,end}_write* to fs.h vfs: separate __sb_start_write into blocking and non-blocking helpers vfs: remove lockdep bogosity in __sb_start_write |
