It is reported that in some cases, write_space may be called in
do_tcp_sendpages, such that we recursively invoke do_tcp_sendpages again:
[ 660.468802] ? do_tcp_sendpages+0x8d/0x580
[ 660.468826] ? tls_push_sg+0x74/0x130 [tls]
[ 660.468852] ? tls_push_record+0x24a/0x390 [tls]
[ 660.468880] ? tls_write_space+0x6a/0x80 [tls]
...
tls_push_sg already does a loop over all sending sg's, so ignore
any tls_write_space notifications until we are done sending.
We then have to call the previous write_space to wake up
poll() waiters after we are done with the send loop.

Commit af503716ac14 ("i2c: core: report OF style module alias for devices
registered via OF") fixed how the I2C core reports the module alias when
devices are registered via OF.
But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its
OF device ID table, so if a Device Tree is using a different one, autoload
won't be working for the module (the matching works because the I2C device
ID table is used as a fallback).
So add compatible strings for each of the entries in the I2C device table.

The automatic update mechanism will trigger an update if the
info block CRCs are different between maxtouch configuration
file (maxtouch.cfg) and chip.
The driver compared the CRCs without retrieving the chip CRC,
resulting always in a failure and firmware flashing action
triggered. Fix this issue by retrieving the chip info block
CRC before the check.
Note that this solution has the benefit that by reading the
information block and the object table into a contiguous region
of memory, we can verify the checksum at probe time. This means
we make sure that we are indeed talking to a chip that supports
object protocol correctly.
Using this patch on a kevin chromebook, the touchscreen and
touchpad drivers are able to match the CRC:

In ethtool_get_rxnfc(), the object "info" is firstly copied from
user-space. If the FLOW_RSS flag is set in the member field flow_type of
"info" (and cmd is ETHTOOL_GRXFH), info needs to be copied again from
user-space because FLOW_RSS is newer and has new definition, as mentioned
in the comment. However, given that the user data resides in user-space, a
malicious user can race to change the data after the first copy. By doing
so, the user can inject inconsistent data. For example, in the second
copy, the FLOW_RSS flag could be cleared in the field flow_type of "info".
In the following execution, "info" will be used in the function
ops->get_rxnfc(). Such inconsistent data can potentially lead to unexpected
information leakage since ops->get_rxnfc() will prepare various types of
data according to flow_type, and the prepared data will be eventually
copied to user-space. This inconsistent data may also cause undefined
behaviors based on how ops->get_rxnfc() is implemented.
This patch simply re-verifies the flow_type field of "info" after the
second copy. If the value is not as expected, an error code will be
returned.

- Fix file size checks when doing INSERT_RANGE that could cause files
to end up negative size if there previously was an extent mapped at
s_maxbytes.
- Fix a bug when doing a remove-then-add ATTR_REPLACE xattr update

causes the attr to be lost and the fs to shut down due to (what it

Pull errseq infrastructure fix from Jeff Layton:
"The PostgreSQL developers recently had a spirited discussion about the
writeback error handling in Linux, and reached out to us about a
behavoir change to the code that bit them when the errseq_t changes
were merged.
When we changed to using errseq_t for tracking writeback errors, we
lost the ability for an application to see a writeback error that
occurred before the open on which the fsync was issued. This was
problematic for PostgreSQL which offloads fsync calls to a completely
separate process from the DB writers.
This patch restores that ability. If the errseq_t value in the inode
does not have the SEEN flag set, then we just return 0 for the sample.
That ensures that any recorded error is always delivered at least
once.
Note that we might still lose the error if the inode gets evicted from
the cache before anything can reopen it, but that was the case before
errseq_t was merged. At LSF/MM we had some discussion about keeping
inodes with unreported writeback errors around in the cache for longer
(possibly indefinitely), but that's really a separate problem"

Tracepoint should only warn when a kernel API user does not respect the
required preconditions (e.g. same tracepoint enabled twice, or called
to remove a tracepoint that does not exist).
Silence warning in out-of-memory conditions, given that the error is
returned to the caller.
This ensures that out-of-memory error-injection testing does not trigger
warnings in tracepoint.c, which were seen by syzbot.

Add support to specify platform specific transition_delay_us instead
of using the transition delay derived from PCC.
With commit 3d41386d556d (cpufreq: CPPC: Use transition_delay_us
depending transition_latency) we are setting transition_delay_us
directly and not applying the LATENCY_MULTIPLIER. Because of that,
on Qualcomm Centriq we can end up with a very high rate of frequency
change requests when using the schedutil governor (default
rate_limit_us=10 compared to an earlier value of 10000).
The PCC subspace describes the rate at which the platform can accept
commands on the CPPC's PCC channel. This includes read and write
command on the PCC channel that can be used for reasons other than
frequency transitions. Moreover the same PCC subspace can be used by
multiple freq domains and deriving transition_delay_us from it as we
do now can be sub-optimal.
Moreover if a platform does not use PCC for desired_perf register then
there is no way to compute the transition latency or the delay_us.
CPPC does not have a standard defined mechanism to get the transition
rate or the latency at the moment.
Given the above limitations, it is simpler to have a platform specific
transition_delay_us and rely on PCC derived value only if a platform
specific value is not available.

- Address an annoying sparse warning due to lost type qualifiers of

the wrong perception that crash kernels actually work there which

for array index
At a commit f91c9d7610a ('ALSA: firewire-lib: cache maximum length of
payload to reduce function calls'), maximum size of payload for tx
isochronous packet is cached to reduce the number of function calls.
This cache was programmed to updated at a first callback of ohci1394 IR
context. However, the maximum size is required to queueing packets before
starting the isochronous context.
As a result, the cached value is reused to queue packets in next time to
starting the isochronous context. Then the cache is updated in a first
callback of the isochronous context. This can cause kernel NULL pointer
dereference in a below call graph:
(sound/firewire/amdtp-stream.c)
amdtp_stream_start()
->queue_in_packet()
->queue_packet()
(drivers/firewire/core-iso.c)
->fw_iso_context_queue()
->struct fw_card_driver.queue_iso()
(drivers/firewire/ohci.c)
= ohci_queue_iso()
->queue_iso_packet_per_buffer()
buffer->pages[page]
The issued dereference occurs in a case that:
- target unit supports different stream formats for sampling transmission
frequency.
- maximum length of payload for tx stream in a first trial is bigger
than the length in a second trial.
In this case, correct number of pages are allocated for DMA and the 'pages'
array has enough elements, while index of the element is wrongly calculated
according to the old value of length of payload in a call of
'queue_in_packet()'. Then it causes the issue.
This commit fixes the critical bug. This affects all of drivers in ALSA
firewire stack in Linux kernel v4.12 or later.

The comment claims that this helper will try not to loose bits, but for
64bit long it looses the high bits before hashing 64bit long into 32bit
int. Use the helper hash_long() to do the right thing for 64bit long.
For 32bit long, there is no change.
All the callers of end_name_hash() either assign the result to
qstr->hash, which is u32 or return the result as an int value (e.g.
full_name_hash()). Change the helper return type to int to conform to
its users.
[ It took me a while to apply this, because my initial reaction to it
was - incorrectly - that it could make for slower code.
After having looked more at it, I take back all my complaints about
the patch, Amir was right and I was mis-reading things or just being
stupid.
I also don't worry too much about the possible performance impact of
this on 64-bit, since most architectures that actually care about
performance end up not using this very much (the dcache code is the
most performance-critical, but the word-at-a-time case uses its own
hashing anyway).
So this ends up being mostly used for filesystems that do their own
degraded hashing (usually because they want a case-insensitive
comparison function).
A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS,
and then this potentially makes things more expensive on 64-bit
architectures with slow or lacking multipliers even for the normal
case.
That said, realistically the only such architecture I can think of is
PA-RISC. Nobody really cares about performance on that, it's more of a
"look ma, I've got warts^W an odd machine" platform.
So the patch is fine, and all my initial worries were just misplaced
from not looking at this properly. - Linus ]

The AFFS filesystem is still in use by m68k community (Link #2), but as
there was no code activity and no maintainer, the filesystem appeared on
the list of candidates for staging/removal (Link #1).
I volunteer to act as a maintainer of AFFS to collect any fixes that
might show up and to guard fs/affs/ against another spring cleaning.

"A bunch of fixes, mostly for existing code and going to stable.
Our memory hot-unplug path wasn't flushing the cache before removing
memory. That is a problem now that we are doing memory hotplug on bare

Three fixes for the NPU code that supports devices connected via
NVLink (ie. GPUs). The main one tweaks the TLB flush algorithm to
avoid soft lockups for large flushes.
A fix for our memory error handling where we would loop infinitely,
returning back to the bad access and hard lockup the CPU.
Fixes for the OPAL RTC driver, which wasn't handling some error cases
correctly.
A fix for a hardlockup in the powernv cpufreq driver.
And finally two fixes to our smp_send_stop(), required due to a recent

efx->type->filter_insert() returns an ID rather than the index that
efx->type->filter_async_insert() used to, which causes it to exceed
efx->type->max_rx_ip_filters on some EF10 configurations, leading to out-
of-bounds array writes.
So, in efx_filter_rfs_work(), convert this back into an index (which is
what the remove call in the expiry path expects, anyway).

For the x32 ABI, struct timeval has two 64-bit fields. However
the kernel currently interprets the user-space values used for
the SO_RCVTIMEO and SO_SNDTIMEO socket options as having a pair
of 32-bit fields.
When the seconds portion of the requested timeout is less than 2**32,
the seconds portion of the effective timeout is correct but the
microseconds portion is zero. When the seconds portion of the
requested timeout is zero and the microseconds portion is non-zero,
the kernel interprets the timeout as zero (never timeout).
Fix by using 64-bit time for SO_RCVTIMEO/SO_SNDTIMEO as required
for the ABI.
The code included below demonstrates the problem.

Pull arm64 fixes from Will Deacon:
"Nothing too bad, but the spectre updates to smatch identified a few
places that may need sanitising so we've got those covered.
Details:
- Close some potential spectre-v1 vulnerabilities found by smatch
- Add missing list sentinel for CPUs that don't require KPTI
- Removal of unused 'addr' parameter for I/D cache coherency
- Removal of redundant set_fs(KERNEL_DS) calls in ptrace
- Fix single-stepping state machine handling in response to kernel
traps
- Clang support for 128-bit integers
- Avoid instrumenting our out-of-line atomics in preparation for
enabling LSE atomics by default in 4.18"
