The phylink_expects_phy() function allows MAC drivers to check if they are
expecting a PHY to attach. The checking condition in phylink_expects_phy()
aims to achieve the same result as the checking condition in
phylink_attach_phy().
However, the checking condition in phylink_expects_phy() uses
pl->link_config.interface, while phylink_attach_phy() uses
pl->link_interface.
Initially, both pl->link_interface and pl->link_config.interface are set
to SGMII, and pl->cfg_link_an_mode is set to MLO_AN_INBAND.
When the interface switches from SGMII to 2500BASE-X,
pl->link_config.interface is updated by phylink_major_config().
At this point, pl->cfg_link_an_mode remains MLO_AN_INBAND, and
pl->link_config.interface is set to 2500BASE-X.
Subsequently, when the STMMAC interface is taken down
administratively and brought back up, it is blocked by
phylink_expects_phy().
Since phylink_expects_phy() and phylink_attach_phy() aim to achieve the
same result, phylink_expects_phy() should check pl->link_interface,
which never changes, instead of pl->link_config.interface, which is
updated by phylink_major_config().

snd_seq_poll() calls snd_seq_write_pool_allocated() that reads out a
field in client->pool object, while it can be updated concurrently via
ioctls, as reported by syzbot. The data race itself is harmless, as
it's merely a poll() call, and the state is volatile. OTOH, the read
out of poll object info from the caller side is fragile, and we can
leave it better in snd_seq_pool_poll_wait() alone.
A similar pattern is seen in snd_seq_kernel_client_write_poll(), too,
which is called from the OSS sequencer.
This patch drops the pool checks from the caller side and add the
pool->lock in snd_seq_pool_poll_wait() for better data consistency.

Others => Other reset events, e.g., power on reset.
On ASPEED platforms, boot status is recorded in the SCU registers.
- AST2400: Only a bit is used to represent system reset triggered by
any WDT controller.
- AST2500/AST2600: System reset triggered by different WDT controllers

When spanning datagram construction over multiple send calls using
MSG_MORE, per datagram settings are configured on the first send.
That is when ip(6)_setup_cork stores these settings for subsequent use
in __ip(6)_append_data and others.
The only flag that escaped this was dontfrag. As a result, a datagram
could be constructed with df=0 on the first sendmsg, but df=1 on a
next. Which is what cmsg_ip.sh does in an upcoming MSG_MORE test in
the "diff" scenario.
Changing datagram conditions in the middle of constructing an skb
makes this already complex code path even more convoluted. It is here
unintentional. Bring this flag in line with expected sockopt/cmsg
behavior.
And stop passing ipc6 to __ip6_append_data, to avoid such issues
in the future. This is already the case for __ip_append_data.
inet6_cork had a 6 byte hole, so the 1B flag has no impact.

When the device stalls an endpoint, current TD is assigned -EPIPE
status and Reset Endpoint is queued. If a Stop Endpoint is pending
at the time, it will run before Reset Endpoint and fail due to the

Endpoint handler runs and initiates giveback.
Check if the stall has already been handled and don't try to do it

not overwriting td->status is the only difference.
I haven't seen this case yet, but I have seen a related one where
the xHC has already executed Reset Endpoint, EP Context state is

nf_conntrack_max and nf_conntrack_expect_max sysctls were authorized to
be written any negative value, which would then be stored in the
unsigned int variables nf_conntrack_max and nf_ct_expect_max variables.
While the do_proc_dointvec_conv function is supposed to limit writing
handled by proc_dointvec proc_handler to INT_MAX. Such a negative value
being written in an unsigned int leads to a very high value, exceeding
this limit.
Moreover, the nf_conntrack_expect_max sysctl documentation specifies the
minimum value is 1.
The proc_handlers have thus been updated to proc_dointvec_minmax in
order to specify the following write bounds :
* Bound nf_conntrack_max sysctl writings between SYSCTL_ZERO
and SYSCTL_INT_MAX.
* Bound nf_conntrack_expect_max sysctl writings between SYSCTL_ONE
and SYSCTL_INT_MAX as defined in the sysctl documentation.
With this patch applied, sysctl writes outside the defined in the bound
will thus lead to a write error :

This reverts commit f590308536 ("timer debug: Hide kernel addresses via
%pK in /proc/timer_list")
The timer list helper SEQ_printf() uses either the real seq_printf() for
procfs output or vprintk() to print to the kernel log, when invoked from
SysRq-q. It uses %pK for printing pointers.
In the past %pK was prefered over %p as it would not leak raw pointer
values into the kernel log. Since commit ad67b74d24 ("printk: hash
addresses printed with %p") the regular %p has been improved to avoid this
issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping looks in atomic contexts.
Switch to the regular pointer formatting which is safer, easier to reason
about and sufficient here.

Currently, the IB uverbs API calls uobj_get_uobj_read(), which in turn
uses the rdma_lookup_get_uobject() helper to retrieve user objects.
In case of failure, uobj_get_uobj_read() returns NULL, overriding the
error code from rdma_lookup_get_uobject(). The IB uverbs API then
translates this NULL to -EINVAL, masking the actual error and
complicating debugging. For example, applications calling ibv_modify_qp
that fails with EBUSY when retrieving the QP uobject will see the
overridden error code EINVAL instead, masking the actual error.
Furthermore, based on rdma-core commit:
"2a22f1ced5f3 ("Merge pull request #1568 from jakemoroni/master")"
Kernel's IB uverbs return values are either ignored and passed on as is
to application or overridden with other errnos in a few cases.
Thus, to improve error reporting and debuggability, propagate the
original error from rdma_lookup_get_uobject() instead of replacing it
with EINVAL.

When dioread_nolock is turned on (the default), it will convert unwritten
extents to written at ext4_end_io_end(), even if the data writeback fails.
It leads to the possibility that stale data may be exposed when the
physical block corresponding to the file data is read-only (i.e., writes
return -EIO, but reads are normal).
Therefore a new ext4_io_end->flags EXT4_IO_END_FAILED is added, which
indicates that some bio write-back failed in the current ext4_io_end.
When this flag is set, the unwritten to written conversion is no longer
performed. Users can read the data normally until the caches are dropped,
after that, the failed extents can only be read to all 0.

a corresponding device tree node, and enable jack detection in a new
machine init function if described.

[ Upstream commit 76b58d5111fdcffce615beb71520bc7a6f1742c9 ]
The chipid macro/variable and regmap_read function call is not needed
because the TPS65219_REG_TI_DEV_ID register value is not a consistent value
across TPS65219 PMIC config versions. Reading from the DEV_ID register
without a consistent value to compare it to isn't useful. There isn't a
way to verify the match data ID is the same ID read from the DEV_ID device
register. 0xF0 isn't a DEV_ID value consistent across TPS65219 NVM
configurations.
For TPS65215, there is a consistent value in bits 5-0 of the DEV_ID
register. However, there are other error checks in place within probe()
that apply to both PMICs rather than keeping this isolated check for one
PMIC.

[ Upstream commit c12bfa0fee65940b10ff5187349f76c6f6b1df9c ]
Each pin can be configured as a Special Function IO (SFIO) or GPIO,
where the SFIO enables the pin to operate in alternative modes such as
I2C, SPI, etc.
The current implementation sets all the pins back to SFIO mode
even if they were initially in GPIO mode. This can cause glitches
on the pins when pinctrl_gpio_free() is called.
Avoid these undesired glitches by storing the pin's SFIO/GPIO
state on GPIO request and restoring it on GPIO free.

[ Upstream commit 2356f15caefc0cc63d9cc5122641754f76ef9b25 ]
On XenServer on Windows machine a platform device with ID 2 instead of
1 is used.
This device is mainly identical to device 1 but due to some Windows
update behaviour it was decided to use a device with a different ID.
This causes compatibility issues with Linux which expects, if Xen
is detected, to find a Xen platform device (5853:0001) otherwise code
will crash due to some missing initialization (specifically grant
tables). Specifically from dmesg
