c1ed39ec11 fs/nls: make load_nls() take a const parameter
load_nls() take a char * parameter, use it to find nls module in list or
construct the module name to load it.

This change make load_nls() take a const parameter, so we don't need do
some cast like this:

        ses->local_nls = load_nls((char *)ctx->local_nls->charset);

d11b0df7dd tcp: Reduce chance of collisions in inet6_hashfn().
For both IPv4 and IPv6 incoming TCP connections are tracked in a hash
table with a hash over the source & destination addresses and ports.
However, the IPv6 hash is insufficient and can lead to a high rate of
collisions.

The IPv6 hash used an XOR to fit everything into the 96 bits for the
fast jenkins hash, meaning it is possible for an external entity to
ensure the hash collides, thus falling back to a linear search in the
bucket, which is slow.

We take the approach of hash the full length of IPv6 address in
__ipv6_addr_jhash() so that all users can benefit from a more secure
version.

While this may look like it adds overhead, the reality of modern CPUs
means that this is unmeasurable in real world scenarios.

In simulating with llvm-mca, the increase in cycles for the hashing
code was ~16 cycles on Skylake (from a base of ~155), and an extra ~9
on Nehalem (base of ~173).

In commit dd6d2910c5e0 ("netfilter: conntrack: switch to siphash")
netfilter switched from a jenkins hash to a siphash, but even the faster
hsiphash is a more significant overhead (~20-30%) in some preliminary
testing.  So, in this patch, we keep to the more conservative approach to
ensure we don't add much overhead per SYN.

In testing, this results in a consistently even spread across the
connection buckets.  In both testing and real-world scenarios, we have
not found any measurable performance impact.

bb7a015636 net: fec: avoid tx queue timeout when XDP is enabled
According to the implementation of XDP of FEC driver, the XDP path
shares the transmit queues with the kernel network stack, so it is
possible to lead to a tx timeout event when XDP uses the tx queue
pretty much exclusively. And this event will cause the reset of the
FEC hardware.
To avoid timeout in this case, we use the txq_trans_cond_update()
interface to update txq->trans_start to jiffies so that watchdog
won't generate a transmit timeout warning.

This log shows that DA7219 AAD interrupt handler da7219_aad_irq_thread()
is unexpectedly running when DA7219 is suspended and should not generate
interrupts. As a result, the IRQ handler is trying to read AAD IRQ event
status over I2C and is hitting the I2C driver "Transfer while suspended"
failure.

Patch #1 adds synchronize_irq() when suspending DA7219, to prevent the
IRQ handler from running after suspending if there is a pending IRQ
generated before suspending. With this patch the above failure is still
reproducible, so this patch does not fix any real observed issue so far,
but at least is useful for confirming that the above issue is not caused
by a pending IRQ but rather looks like a DA7219 hardware issue with an
unexpectedly generated IRQ.

Patch #2 does not fix the above issue either, but it prevents its
potentially harmful side effects. With the existing code, if the issue
occurs and the IRQ handler fails to read the AAD IRQ events status over
I2C, it does not check that and tries to use the garbage uninitialized
value of the events status, potentially reporting bogus events. This
patch fixes that by adding missing error checking.

In fact I'm sending these patches not only to submit them for review but
also to ask Renesas folks for any hints on a possible cause of the
described DA7219 issue (AAD interrupts spuriously firing after jack
detection is already disabled) or how to debug it further.

856d8e3c63 s390/dasd: print copy pair message only for the correct error
The DASD driver has certain types of requests that might be rejected by
the storage server or z/VM because they are not supported. Since the
missing support of the command is not a real issue there is no user
visible kernel error message for this.

For copy pair setups  there is a specific error that IO is not allowed on
secondary devices. This error case is explicitly handled and an error
message is printed.

The code checking for the error did use a bitwise 'and' that is used to
check for specific bits. But in this case the whole sense byte has to
match.

This leads to the problem that the copy pair related error message is
erroneously printed for other error cases that are usually not reported.
This might heavily confuse users and lead to follow on actions that might
disrupt application processing.

Fix by checking the sense byte for the exact value and not single bits.

8a2278ce9c s390/dasd: fix hanging device after request requeue
The DASD device driver has a function to requeue requests to the
blocklayer.
This function is used in various cases when basic settings for the device
have to be changed like High Performance Ficon related parameters or copy
pair settings.

The functions iterates over the device->ccw_queue and also removes the
requests from the block->ccw_queue.
In case the device is started on an alias device instead of the base
device it might be removed from the block->ccw_queue without having it
canceled properly before. This might lead to a hanging device since the
request is no longer on a queue and can not be handled properly.

Fix by iterating over the block->ccw_queue instead of the
device->ccw_queue. This will take care of all blocklayer related requests
and handle them on all associated DASD devices.

acea28a6b7 s390/dasd: use correct number of retries for ERP requests
If a DASD request fails an error recovery procedure (ERP) request might
be built as a copy of the original request to do error recovery.

The ERP request gets a number of retries assigned.
This number is always 256 no matter what other value might have been set
for the original request. This is not what is expected when a user
specifies a certain amount of retries for the device via sysfs.

Correctly use the number of retries of the original request for ERP

05f1d8ed03 s390/dasd: fix hanging device after quiesce/resume
Quiesce and resume are functions that tell the DASD driver to stop/resume
issuing I/Os to a specific DASD.

On resume dasd_schedule_block_bh() is called to kick handling of IO
requests again. This does unfortunately not cover internal requests which
are used for path verification for example.

This could lead to a hanging device when a path event or anything else
that triggers internal requests occurs on a quiesced device.

Fix by also calling dasd_schedule_device_bh() which triggers handling of
internal requests on resume.

7b72d661f1 io_uring: gate iowait schedule on having pending requests
A previous commit made all cqring waits marked as iowait, as a way to
improve performance for short schedules with pending IO. However, for
use cases that have a special reaper thread that does nothing but
wait on events on the ring, this causes a cosmetic issue where we
know have one core marked as being "busy" with 100% iowait.

While this isn't a grave issue, it is confusing to users. Rather than
always mark us as being in iowait, gate setting of current->in_iowait
to 1 by whether or not the waiting task has pending requests.

20ea1e7d13 file: always lock position for FMODE_ATOMIC_POS
The pidfd_getfd() system call allows a caller with ptrace_may_access()
abilities on another process to steal a file descriptor from this
process. This system call is used by debuggers, container runtimes,
system call supervisors, networking proxies etc. So while it is a
special interest system call it is used in common tools.

That ability ends up breaking our long-time optimization in fdget_pos(),
which "knew" that if we had exclusive access to the file descriptor
nobody else could access it, and we didn't need the lock for the file
position.

That check for file_count(file) was always fairly subtle - it depended
on __fdget() not incrementing the file count for single-threaded
processes and thus included that as part of the rule - but it did mean
that we didn't need to take the lock in all those traditional unix
process contexts.

So it's sad to see this go, and I'd love to have some way to re-instate
the optimization. At the same time, the lock obviously isn't ever
contended in the case we optimized, so all we were optimizing away is
the atomics and the cacheline dirtying. Let's see if anybody even
notices that the optimization is gone.

d8ccbd2191 btrfs: remove BUG_ON()'s in add_new_free_space()
At add_new_free_space() we have these BUG_ON()'s that are there to deal
with any failure to add free space to the in memory free space cache.
Such failures are mostly -ENOMEM that should be very rare. However there's
no need to have these BUG_ON()'s, we can just return any error to the
caller and all callers and their upper call chain are already dealing with
errors.

So just make add_new_free_space() return any errors, while removing the
BUG_ON()'s, and returning the total amount of added free space to an
optional u64 pointer argument.

In VXLAN-GPE, there may not be an Ethernet header following the VXLAN
header. But in GRO, the vxlan driver calls eth_gro_receive
unconditionally, which means the following header is incorrectly parsed

Introduce GPE specific GRO handling.

For better performance, do not check for GPE during GRO but rather
install a different set of functions at setup time.

94d166c531 vxlan: calculate correct header length for GPE
VXLAN-GPE does not add an extra inner Ethernet header. Take that into
account when calculating header length.

This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is
cached.

In the collect_md mode (which is the only mode that VXLAN-GPE
supports), there's no magic auto-setting of the tunnel interface MTU.
It can't be, since the destination and thus the underlying interface
may be different for each packet.

So, the administrator is responsible for setting the correct tunnel
interface MTU. Apparently, the administrators are capable enough to
calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36).
They set the tunnel interface MTU to 1464. If you run a TCP stream over
such interface, it's then segmented according to the MTU 1464, i.e.
producing 1514 bytes frames. Which is okay, this still fits the lower
MTU.

However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as
the header size and thus incorrectly calculates the frame size to be
1528. This leads to ICMP too big message being generated (locally),
PMTU of 1450 to be cached and the TCP stream to be resegmented.

The fix is to use the correct actual header size, especially for
skb_tunnel_check_pmtu calculation.

The decision whether to enable a wake irq during suspend can not be done
based on the runtime PM state directly as a driver may use wake irqs
without implementing runtime PM. Such drivers specifically leave the
state set to the default 'suspended' and the wake irq is thus never
enabled at suspend.

Add a new wake irq flag to track whether a dedicated wake irq has been
enabled at runtime suspend and therefore must not be enabled at system
suspend.

Note that pm_runtime_enabled() can not be used as runtime PM is always
disabled during late suspend.

ac4436a5b2 thermal: of: fix double-free on unregistration
Since commit 3d439b1a2ad3 ("thermal/core: Alloc-copy-free the thermal
zone parameters structure"), thermal_zone_device_register() allocates
a copy of the tzp argument and frees it when unregistering, so
thermal_of_zone_register() now ends up leaking its original tzp and
double-freeing the tzp copy. Fix this by locating tzp on stack instead.

80ddce5f2d thermal: core: constify params in thermal_zone_device_register
Since commit 3d439b1a2ad3 ("thermal/core: Alloc-copy-free the thermal zone
parameters structure"), thermal_zone_device_register() allocates a copy
of the tzp argument and callers need not explicitly manage its lifetime.

This means the function no longer cares about the parameter being
mutable, so constify it.

No functional change.

9e46e4dcd9 mm,memblock: reset memblock.reserved to system init state to prevent UAF
The memblock_discard function frees the memblock.reserved.regions
array, which is good.

However, if a subsequent memblock_free (or memblock_phys_free) comes
in later, from for example ima_free_kexec_buffer, that will result in
a use after free bug in memblock_isolate_range.

When running a kernel with CONFIG_KASAN enabled, this will cause a
kernel panic very early in boot. Without CONFIG_KASAN, there is
a chance that memblock_isolate_range might scribble on memory
that is now in use by somebody else.

Avoid those issues by making sure that memblock_discard points
memblock.reserved.regions back at the static buffer.

If memblock_free is called after memblock memory is discarded, that will
print a warning in memblock_remove_region.

ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect
Add a quirk mechanism to allow specifying that active-high jack-detection
should be used on platforms where this info is not available in devicetree.

And add an entry for the Positivo CW14Q01P-V2 to the DMI table, so that
jack-detection will work properly on this laptop.

ASoC: da7219: Check for failure reading AAD IRQ events
When handling an AAD interrupt, if IRQ events read failed (for example,
due to i2c "Transfer while suspended" failure, i.e. when attempting to
read it while DA7219 is suspended, which may happen due to a spurious
AAD interrupt), the events array contains garbage uninitialized values.
So instead of trying to interprete those values and doing any actions
based on them (potentially resulting in misbehavior, e.g. reporting
bogus events), refuse to handle the interrupt.

ASoC: da7219: Flush pending AAD IRQ when suspending
da7219_aad_suspend() disables jack detection, which should prevent
generating new interrupts by DA7219 while suspended. However, there is a
theoretical possibility that there is a pending interrupt generated just
before suspending DA7219 and not handled yet, so the IRQ handler may
still run after DA7219 is suspended. To prevent that, wait until the
pending IRQ handling is done.

This patch arose as an attempt to fix the following I2C failure
occurring sometimes during system suspend or resume:

which indicates that the AAD IRQ handler is unexpectedly running when
DA7219 is suspended, and as a result, is trying to read data from DA7219
over I2C and is hitting the I2C driver "Transfer while suspended"
failure.

However, with this patch the above failure is still reproducible. So
this patch does not fix any real observed issue so far, but at least is
useful for confirming that the above issue is not caused by a pending
IRQ but rather looks like a DA7219 hardware issue with an IRQ
unexpectedly generated after jack detection is already disabled.
