#1555407 — [PATCH 4.9 188/206] xfs: pass post-eof speculative prealloc blocks to bmapi

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Brian Foster <bfoster@redhat.com>

commit f782088c9e5d08e9494c63e68b4e85716df3e5f8 upstream.

xfs_file_iomap_begin_delay() implements post-eof speculative
preallocation by extending the block count of the requested delayed
allocation. Now that xfs_bmapi_reserve_delalloc() has been updated to
handle prealloc blocks separately and tag the inode, update
xfs_file_iomap_begin_delay() to use the new parameter and rely on the
former to tag the inode.

Note that this patch does not change behavior.

#1555408 — [PATCH 4.9 198/206] xfs: dont cap maximum dedupe request length

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit 1bb33a98702d8360947f18a44349df75ba555d5d upstream.

After various discussions on linux-fsdevel, it has been decided that it
is not necessary to cap the length of a dedupe request, and that
correctly-written userspace client programs will be able to absorb the
change.  Therefore, remove the length clamping behavior.

#1555409 — [PATCH 4.9 203/206] xfs: fix crash and data corruption due to removal of busy COW extents

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


commit a1b7a4dea6166cf46be895bce4aac67ea5160fe8 upstream.

There is a race window between write_cache_pages calling
clear_page_dirty_for_io and XFS calling set_page_writeback, in which
the mapping for an inode is tagged neither as dirty, nor as writeback.

If the COW shrinker hits in exactly that window we'll remove the delayed
COW extents and writepages trying to write it back, which in release
kernels will manifest as corruption of the bmap btree, and in debug
kernels will trip the ASSERT about now calling xfs_bmapi_write with the
COWFORK flag for holes.  A complex customer load manages to hit this
window fairly reliably, probably by always having COW writeback in flight
while the cow shrinker runs.

This patch adds another check for having the I_DIRTY_PAGES flag set,
which is still set during this race window.  While this fixes the problem
I'm still not overly happy about the way the COW shrinker works as it
still seems a bit fragile.

#1555412 — [PATCH 4.9 112/206] clk: qcom: ipq806x: Fix board clk rates

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stephen Boyd <sboyd@codeaurora.org>

commit cbf2e548ca8ad4bb274d014e9a70bd841d29948e upstream.

The clocks on these boards run at 25 MHz, not 19.2 and 27 like
other platforms. Unfortunately I copy/pasted from other similar
SoCs but forgot this one is different. Fix it.

#1555413 — [PATCH 4.9 179/206] xfs: fix unbalanced inode reclaim flush locking

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Brian Foster <bfoster@redhat.com>

commit 98efe8af1c9ffac47e842b7a75ded903e2f028da upstream.

Filesystem shutdown testing on an older distro kernel has uncovered an
imbalanced locking pattern for the inode flush lock in
xfs_reclaim_inode(). Specifically, there is a double unlock sequence
between the call to xfs_iflush_abort() and xfs_reclaim_inode() at the
"reclaim:" label.

This actually does not cause obvious problems on current kernels due to
the current flush lock implementation. Older kernels use a counting
based flush lock mechanism, however, which effectively breaks the lock
indefinitely when an already unlocked flush lock is repeatedly unlocked.
Though this only currently occurs on filesystem shutdown, it has
reproduced the effect of elevating an fs shutdown to a system-wide crash
or hang.

As it turns out, the flush lock is not actually required for the reclaim
logic in xfs_reclaim_inode() because by that time we have already cycled
the flush lock once while holding ILOCK_EXCL. Therefore, remove the
additional flush lock/unlock cycle around the 'reclaim:' label and
update branches into this label to release the flush lock where
appropriate. Add an assert to xfs_ifunlock() to help prevent future
occurences of the same problem.

4.9-stable review patch.  If anyone has any objections, please let me know.

commit 6b7df3ce92ac82ec3f4a2953b6fed77da7b38aaa upstream.

__s390_dma_map_sg maps a dma-contiguous area. Although we only map
whole pages we have to take into account that the area doesn't start
or stop at a page boundary because we use the dma address to loop
over the individual sg entries. Failing to do that might lead to an
access of the wrong sg entry.

#1555415 — [PATCH 4.9 189/206] xfs: Move AGI buffer type setting to xfs_read_agi

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Eric Sandeen <sandeen@sandeen.net>

commit 200237d6746faaeaf7f4ff4abbf13f3917cee60a upstream.

We've missed properly setting the buffer type for
an AGI transaction in 3 spots now, so just move it
into xfs_read_agi() and set it if we are in a transaction
to avoid the problem in the future.

This is similar to how it is done in i.e. the dir3
and attr3 read functions.

#1555419 — [PATCH 4.9 176/206] xfs: dont BUG() on mixed direct and mapped I/O

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Brian Foster <bfoster@redhat.com>

commit 04197b341f23b908193308b8d63d17ff23232598 upstream.

We've had reports of generic/095 causing XFS to BUG() in
__xfs_get_blocks() due to the existence of delalloc blocks on a
direct I/O read. generic/095 issues a mix of various types of I/O,
including direct and memory mapped I/O to a single file. This is
clearly not supported behavior and is known to lead to such
problems. E.g., the lack of exclusion between the direct I/O and
write fault paths means that a write fault can allocate delalloc
blocks in a region of a file that was previously a hole after the
direct read has attempted to flush/inval the file range, but before
it actually reads the block mapping. In turn, the direct read
discovers a delalloc extent and cannot proceed.

While the appropriate solution here is to not mix direct and memory
mapped I/O to the same regions of the same file, the current
BUG_ON() behavior is probably overkill as it can crash the entire
system.  Instead, localize the failure to the I/O in question by
returning an error for a direct I/O that cannot be handled safely
due to delalloc blocks. Be careful to allow the case of a direct
write to post-eof delalloc blocks. This can occur due to speculative
preallocation and is safe as post-eof blocks are not accompanied by
dirty pages in pagecache (conversely, preallocation within eof must
have been zeroed, and thus dirtied, before the inode size could have
been increased beyond said blocks).

Finally, provide an additional warning if a direct I/O write occurs
while the file is memory mapped. This may not catch all problematic
scenarios, but provides a hint that some known-to-be-problematic I/O
methods are in use.

It turns out that btrfs and xfs had differing interpretations of what
to do when the dedupe length is zero.  Change xfs to follow btrfs'
semantics so that the userland interface is consistent.

#1555425 — [PATCH 4.9 121/206] iommu/vt-d: Fix pasid table size encoding

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jacob Pan <jacob.jun.pan@linux.intel.com>

commit 65ca7f5f7d1cdde6c25172fe6107cd16902f826f upstream.

Different encodings are used to represent supported PASID bits
and number of PASID table entries.
The current code assigns ecap_pss directly to extended context
table entry PTS which is wrong and could result in writing
non-zero bits to the reserved fields. IOMMU fault reason
11 will be reported when reserved bits are nonzero.
This patch converts ecap_pss to extend context entry pts encoding
based on VT-d spec. Chapter 9.4 as follows:
 - number of PASID bits = ecap_pss + 1
 - number of PASID table entries = 2^(pts + 5)
Software assigned limit of pasid_max value is also respected to
match the allocation limitation of PASID table.

#1555426 — [PATCH 4.9 184/206] xfs: track preallocation separately in xfs_bmapi_reserve_delalloc()

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Brian Foster <bfoster@redhat.com>

commit 974ae922efd93b07b6cdf989ae959883f6f05fd8 upstream.

Speculative preallocation is currently processed entirely by the callers
of xfs_bmapi_reserve_delalloc(). The caller determines how much
preallocation to include, adjusts the extent length and passes down the
resulting request.

While this works fine for post-eof speculative preallocation, it is not
as reliable for COW fork preallocation. COW fork preallocation is
implemented via the cowextszhint, which aligns the start offset as well
as the length of the extent. Further, it is difficult for the caller to
accurately identify when preallocation occurs because the returned
extent could have been merged with neighboring extents in the fork.

To simplify this situation and facilitate further COW fork preallocation
enhancements, update xfs_bmapi_reserve_delalloc() to take a separate
preallocation parameter to incorporate into the allocation request. The
preallocation blocks value is tacked onto the end of the request and
adjusted to accommodate neighboring extents and extent size limits.
Since xfs_bmapi_reserve_delalloc() now knows precisely how much
preallocation was included in the allocation, it can also tag the inodes
appropriately to support preallocation reclaim.

Note that xfs_bmapi_reserve_delalloc() callers are not yet updated to
use the preallocation mechanism. This patch should not change behavior
outside of correctly tagging reflink inodes when start offset
preallocation occurs (which the caller does not handle correctly).

#1555427 — [PATCH 4.9 175/206] xfs: dont skip cow forks w/ delalloc blocks in cowblocks scan

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Brian Foster <bfoster@redhat.com>

commit 399372349a7f9b2d7e56e4fa4467c69822d07024 upstream.

The cowblocks background scanner currently clears the cowblocks tag
for inodes without any real allocations in the cow fork. This
excludes inodes with only delalloc blocks in the cow fork. While we
might never expect to clear delalloc blocks from the cow fork in the
background scanner, it is not necessarily correct to clear the
cowblocks tag from such inodes.

For example, if the background scanner happens to process an inode
between a buffered write and writeback, the scanner catches the
inode in a state after delalloc blocks have been allocated to the
cow fork but before the delalloc blocks have been converted to real
blocks by writeback. The background scanner then incorrectly clears
the cowblocks tag, even if part of the aforementioned delalloc
reservation will not be remapped to the data fork (i.e., extra
blocks due to the cowextsize hint). This means that any such
additional blocks in the cow fork might never be reclaimed by the
background scanner and could persist until the inode itself is
reclaimed.

To address this problem, only skip and clear inodes without any cow
fork allocations whatsoever from the background scanner. While we
generally do not want to cancel delalloc reservations from the
background scanner, the pagecache dirty check following the
cowblocks check should prevent that situation. If we do end up with
delalloc cow fork blocks without a dirty address space mapping, this
is probably an indication that something has gone wrong and the
blocks should be reclaimed, as they may never be converted to a real
allocation.

#1555429 — [PATCH 4.9 180/206] xfs: new inode extent list lookup helpers

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


commit 93533c7855c3c78c8a900cac65c8d669bb14935d upstream.

xfs_iext_lookup_extent looks up a single extent at the passed in offset,
and returns the extent covering the area, or the one behind it in case
of a hole, as well as the index of the returned extent in arguments,
as well as a simple bool as return value that is set to false if no
extent could be found because the offset is behind EOF.  It is a simpler
replacement for xfs_bmap_search_extent that leaves looking up the rarely
needed previous extent to the caller and has a nicer calling convention.

xfs_iext_get_extent is a helper for iterating over the extent list,
it takes an extent index as input, and returns the extent at that index
in it's expanded form in an argument if it exists.  The actual return
value is a bool whether the index is valid or not.

#1555441 — [PATCH 4.9 150/206] crypto: arm64/sha1-ce - fix for big endian

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ard Biesheuvel <ard.biesheuvel@linaro.org>

commit ee71e5f1e7d25543ee63a80451871f8985b8d431 upstream.

The SHA1 digest is an array of 5 32-bit quantities, so we should refer
to them as such in order for this code to work correctly when built for
big endian. So replace 16 byte scalar loads and stores with 4x4 vector
ones where appropriate.
