The ->writepage() and ->writepages() operations are supposed to write
entire pages. However, on filesystems with a block size smaller than
PAGE_SIZE, __gfs2_jdata_writepage() only adds the first block to the
current transaction instead of adding the entire page. Fix that.

In gfs2_make_fs_rw(), make sure to call gfs2_consist() to report an
inconsistency and mark the filesystem as withdrawn when
gfs2_find_jhead() fails.
At the end of gfs2_make_fs_rw(), when we discover that the filesystem
has been withdrawn, make sure we report an error. This also replaces
the gfs2_withdrawn() check after gfs2_find_jhead().

This reverts commit 970343cd49 ("GFS2: free disk inode which is
deleted by remote node -V2").
The original intent behind commit 970343cd49 was to cull dentries when a
remote node requests to demote an iopen glock, which happens when the
remote node tries to delete the inode. This is now handled by
gfs2_try_evict(), which is called via iopen_go_callback() ->
gfs2_queue_try_to_evict().

In gfs2_kill_sb(), flush the delete work queue after setting the
SDF_DEACTIVATING flag. This ensures that no new inodes will be
instantiated anymore, and the inode cache will be empty after the
following kill_block_super() -> generic_shutdown_super() ->
evict_inodes() call.
With that, function gfs2_make_fs_ro() now calls gfs2_flush_delete_work()
after the workqueue has been destroyed. Skip that by checking for the
presence of the SDF_DEACTIVATING flag.

Add a check to delete_work_func() so that it quits when it finds that

delete work while the filesystem is deactivating.

Function gfs2_clear_rgrpd() is called during unmount to free all rgrps
and their sub-objects. If the rgrp glock is held (e.g. in SH) it calls
gfs2_glock_cb() to unlock, then calls flush_delayed_work() to make
sure any glock work is finished. However, there is a race with other
cluster nodes who may request the rgrp glock in another mode (say, EX).
Func gfs2_clear_rgrpd() calls glock_clear_object() which sets gl_object
to NULL but that's done without holding the gl_lockref spin_lock.
While the lock is not held Another node's demote request can cause the
state machine to run again, and since the gl_lockref is released in
do_xmote, the second process's call to do_xmote can call go_inval
(rgrp_go_inval) after the gl_object has been cleared, which results in
NULL pointer reference of the rgrp glock's gl_object.
Other go_inval glops functions don't require the gl_object to exist, as
evidenced by function inode_go_inval() which explicitly checks for if
(ip) before referencing gl_object. This patch does the same thing
for rgrp glocks. Both the go_inval and go_sync ops are patched to check
the existence of gl_object (rgd) before trying to dereference it.

Function delete_work_func() is used for two purposes:
* to immediately try to evict the glock's inode, and
* to verify after a little while that the inode has been deleted as
expected, and didn't just get skipped.
These two operations are not separated very well, so introduce two new
glock flags to improved that. Split gfs2_queue_delete_work() into
gfs2_queue_try_to_evict and gfs2_queue_verify_evict().

Get rid of the GLF_PENDING_DELETE glock flag introduced by commit
a0e3cc65fa ("gfs2: Turn gl_delete into a delayed work"). The only use
of that flag is to prevent the iopen glock from being demoted (i.e.,
unlocked) while delete work is pending. It turns out that demoting the
iopen glock while delete work is pending is perfectly fine; we only need
to make sure that the glock isn't being freed while still in use. This
is ensured by the previous patch because delete_work_func() owns a
reference while the work is queued or running.
With these changes, gfs2_queue_delete_work() no longer takes the glock
spin lock, so we can use it in iopen_go_callback() instead of
open-coding it there.

In __gfs2_glock_put(), remove the glock from the lru list *after*
dropping the glock lock. This prevents deadlocks against
gfs2_scan_glock_lru().
In gfs2_scan_glock_lru(), make sure that the glock's reference count is
zero before moving the glock to the dispose list. This skips glocks
that are marked dead as well as glocks that are still in use.
Additionally, switch to spin_trylock() as we already do in
gfs2_dispose_glock_lru(); this alone would also be enough to prevent
deadlocks against __gfs2_glock_put().

Improve the comment describing the inode and iopen glock interactions
and the glock poking related to inode evict.
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
Function glock_clear_object() checks if the specified glock is still
pointing at the right object and clears the gl_object pointer. To
handle the case of incompletely constructed inodes, glock_clear_object()
also allows gl_object to be NULL.
However, in the teardown case, when iget_failed() is called and the
inode is removed from the inode hash, by the time we get to the
glock_clear_object() calls in gfs2_put_super() and its helpers, we don't
have exclusion against concurrent gfs2_inode_lookup() and
gfs2_create_inode() calls, and the inode and iopen glocks may already be
pointing at another inode, so the checks in glock_clear_object() are
incorrect.
To better handle this case, always completely disassociate an inode from
its glocks before tearing it down. In addition, get rid of a duplicate
glock_clear_object() call in gfs2_evict_inode(). That way,
glock_clear_object() will only ever be called when the glock points at
the current inode, and the NULL check in glock_clear_object() can be
removed.

Revert "gfs2: stop using generic_writepages in gfs2_ail1_start_one"
Commit b2b0a5e978 switched from generic_writepages() to
filemap_fdatawrite_wbc() in gfs2_ail1_start_one() on the path to
replacing ->writepage() with ->writepages() and eventually eliminating
the former. Function gfs2_ail1_start_one() is called from
gfs2_log_flush(), our main function for flushing the filesystem log.
Unfortunately, at least as implemented today, ->writepage() and
->writepages() are entirely different operations for journaled data
inodes: while the former creates and submits transactions covering the
data to be written, the latter flushes dirty buffers out to disk.
With gfs2_ail1_start_one() now calling ->writepages(), we end up
creating filesystem transactions while we are in the course of a log
flush, which immediately deadlocks on the sdp->sd_log_flush_lock
semaphore.
Work around that by going back to how things used to work before commit
b2b0a5e978 for now; figuring out a superior solution will take time we
don't have available right now. However ...
Since the removal of generic_writepages() is imminent, open-code it
here. We're already inside a blk_start_plug() ... blk_finish_plug()
section here, so skip that part of the original generic_writepages().
This reverts commit b2b0a5e978.

We potentially have old hashes of the xattr names generated on systems
with signed 'char' types. Now that everybody uses '-funsigned-char',
those hashes will no longer match.
This only happens if you use xattrs names that have the high bit set,
which probably doesn't happen in practice, but the xfstest generic/454
shows it.
Instead of adding a new "signed xattr hash filesystem" bit and having to
deal with all the possible combinations, just calculate the hash both
ways if the first one fails, and always generate new hashes with the
proper unsigned char version.

do_prlimit() adds the user-controlled resource value to a pointer that
will subsequently be dereferenced. In order to help prevent this
codepath from being used as a spectre "gadget" a barrier needs to be
added after checking the range.

A previous commit fixed a poll race that can occur, but it's only
applicable for multishot requests. For a multishot request, we can safely
ignore a spurious wakeup, as we never leave the waitqueue to begin with.
A blunt reissue of a multishot armed request can cause us to leak a
buffer, if they are ring provided. While this seems like a bug in itself,
it's not really defined behavior to reissue a multishot request directly.
It's less efficient to do so as well, and not required to rearm anything
like it is for singleshot poll requests.

Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
including:
- A regression fix for SDHCI controllers on Inforce 6540, and
another SDHCI fix on SM8350
- Reenable cluster idle on sm8250 after the the code fix is upstream
- multiple fixes for the QMP PHY binding, needing an incompatible
dt change
- The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
6P, to avoid instabilities caused by use of protected memory regions
- Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
clock error
- A couple of verdin-imx8mm DT fixes for audio playback support
- Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees
- Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
eMMC CMD8 CRC error in HS400ES/HS400 mode
The remaining ARM and RISC-V platforms only have very few
smaller dts bugfixes this time:
- A fix for the SiFive unmatched board's PCI memory space
- A revert to fix a regression with GPIO on Marvell Armada
- A fix for the UART address on Marvell AC5
- Missing chip-select phandles for stm32 boards
- Selecting the correct clock for the sam9x60 memory controller
- Amlogic based Odroid-HC4 needs a revert to restore USB
functionality.
And finally, there are some minor code fixes:
- Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
firmware
- memory controller driver fixes for an OMAP regression and older bugs
on tegra, atmel and mvebu
- reset controller fixes for ti-sci and uniphier platforms
- ARM SCMI firmware fixes for a couple of rare corner cases
- Qualcomm platform driver fixes for incorrect error handling and a
backwards compatibility fix for the apr driver using older dtb
- NXP i.MX SoC driver fixes for HDMI output, error handling in the imx8
soc-id and missing reference counting on older cpuid code

IORING_SETUP_R_DISABLED rings don't have the submitter task set, so
it's not always safe to use ->submitter_task. Disallow posting msg_ring
messaged to disabled rings. Also add task NULL check for loosy sync
around testing for IORING_SETUP_R_DISABLED.

There is a couple of problems with queueing a tw in io_msg_ring_data()
for remote execution. First, once we queue it the target ring can
go away and so setting IORING_SQ_TASKRUN there is not safe. Secondly,
the userspace might not expect IORING_SQ_TASKRUN.
Extract a helper and uniformly use TWA_SIGNAL without TWA_SIGNAL_NO_IPI
tricks for now, just as it was done in the original patch.
