[ Upstream commit 26a22194927e8521e304ed75c2f38d8068d55fc7 ]
If cls_bpf_offload errors out, we must also undo tcf_bind_filter that
was done before the error.
Fix that by calling tcf_unbind_filter in errout_parms.

[ Upstream commit 1d6d537dc55d1f42d16290f00157ac387985b95b ]
Move the call to of_get_ethdev_address to mtk_add_mac which is part of
the probe function and can hence itself return -EPROBE_DEFER should
of_get_ethdev_address return -EPROBE_DEFER. This allows us to entirely
get rid of the mtk_init function.
The problem of of_get_ethdev_address returning -EPROBE_DEFER surfaced
in situations in which the NVMEM provider holding the MAC address has
not yet be loaded at the time mtk_eth_soc is initially probed. In this
case probing of mtk_eth_soc should be deferred instead of falling back
to use a random MAC address, so once the NVMEM provider becomes
available probing can be repeated.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount

up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
There are roughly 40 places where netdev->dev_addr is passed
as the destination to a of_get_mac_address() call. Add a helper
which takes a dev pointer instead, so it can call an appropriate
helper.
Note that of_get_mac_address() already assumes the address is
6 bytes long (ETH_ALEN) so use eth_hw_addr_set().

On ASUS TUF A16 it is reported that the ITE5570 ACPI device connected to
GPIO 7 is causing an interrupt storm. This issue doesn't happen on
Windows.
Comparing the GPIO register configuration between Windows and Linux
bit 20 has been configured as a pull up on Windows, but not on Linux.
Checking GPIO declaration from the firmware it is clear it *should* have
been a pull up on Linux as well.
```
GpioInt (Level, ActiveLow, Exclusive, PullUp, 0x0000,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,)
{ // Pin list
0x0007
}
```
On Linux amd_gpio_set_config() is currently only used for programming
the debounce. Actually the GPIO core calls it with all the arguments
that are supported by a GPIO, pinctrl-amd just responds `-ENOTSUPP`.
To solve this issue expand amd_gpio_set_config() to support the other
arguments amd_pinconf_set() supports, namely `PIN_CONFIG_BIAS_PULL_DOWN`,
`PIN_CONFIG_BIAS_PULL_UP`, and `PIN_CONFIG_DRIVE_STRENGTH`.

[ Upstream commit 1feece2780ac2f8de45177fe53979726cee4b3d1 ]
-L only specifies the search path for libraries directly provided in the
link line with -l. Because -lopencsd isn't specified, it's only linked
because it's a dependency of -lopencsd_c_api. Dependencies like this are
resolved using the default system search paths or -rpath-link=... rather
than -L. This means that compilation only works if OpenCSD is installed
to the system rather than provided with the CSLIBS (-L) option.
This could be fixed by adding -Wl,-rpath-link=$(CSLIBS) but that is less
conventional than just adding -lopencsd to the link line so that it uses
-L. -lopencsd seems to have been removed in commit ed17b1914978eddb
("perf tools: Drop requirement for libstdc++.so for libopencsd check")
because it was thought that there was a chance compilation would work
even if it didn't exist, but I think that only applies to libstdc++ so
there is no harm to add it back. libopencsd.so and libopencsd_c_api.so
would always exist together.

commit 6909cf5c4101214f4305a62d582a5b93c7e1eb9a upstream.
When run on a file system where the inline_data feature has been
enabled, xfstests generic/269, generic/270, and generic/476 cause ext4
to emit error messages indicating that inline directory entries are
corrupted. This occurs because the inline offset used to locate
inline directory entries in the inode body is not updated when an
xattr in that shared region is deleted and the region is shifted in
memory to recover the space it occupied. If the deleted xattr precedes
the system.data attribute, which points to the inline directory entries,
that attribute will be moved further up in the region. The inline
offset continues to point to whatever is located in system.data's former
location, with unfortunate effects when used to access directory entries
or (presumably) inline data in the inode body.

commit a460beefe77d780ac48f19d39333852a7f93ffc1 upstream.
[WHY]
All of pipes will be used when the MPC split enable on the dcn
which just has 2 pipes. Then MPO enter will trigger the minimal
transition which need programe dcn from 2 pipes MPC split to 2
pipes MPO. This action will cause lag if happen frequently.
[HOW]
Disable the MPC split for the platform which dcn resource is limited

Could not match regex pattern. Verify command output:

It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

commit 0c9d2eb5e94792fe64019008a04d4df5e57625af upstream.
The SMBus I2C buses have limits on the size of transfers they can do but
do not factor in the register length meaning we may try to do a transfer
longer than our length limit, the core will not take care of this.
Future changes will factor this out into the core but there are a number
of users that assume current behaviour so let's just do something
conservative here.
This does not take account padding bits but practically speaking these
are very rarely if ever used on I2C buses given that they generally run
slowly enough to mean there's no issue.

When problems were noticed with the register address not being taken
into account when limiting raw transfers with I2C devices we fixed this
in the core. Unfortunately it has subsequently been realised that a lot
of buses were relying on the prior behaviour, partly due to unclear
documentation not making it obvious what was intended in the core. This
is all more involved to fix than is sensible for a fix commit so let's
just drop the original fixes, a separate commit will fix the originally
observed problem in an I2C specific way

When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:
not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds
The timeout had been introduced 3 years ago, see the Fixes commit below.
This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.
The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

Fuse shouldn't return ENOSYS from its ioctl implementation. If userspace
responds with ENOSYS it should be translated to ENOTTY.
There are two ways to return an error from the IOCTL request:
- fuse_out_header.error

commit d55901522f96082a43b9842d34867363c0cdbac5 upstream.
When making a DNS query inside the kernel using dns_query(), the request
code can in rare cases end up creating a duplicate index key in the
assoc_array of the destination keyring. It is eventually found by
a BUG_ON() check in the assoc_array implementation and results in
a crash.

The situation occurs as follows:
* Some kernel facility invokes dns_query() to resolve a hostname, for
example, "abcdef". The function registers its global DNS resolver
cache as current->cred.thread_keyring and passes the query to
request_key_net() -> request_key_tag() -> request_key_and_link().
* Function request_key_and_link() creates a keyring_search_context
object. Its match_data.cmp method gets set via a call to
type->match_preparse() (resolves to dns_resolver_match_preparse()) to
dns_resolver_cmp().
* Function request_key_and_link() continues and invokes
search_process_keyrings_rcu() which returns that a given key was not
found. The control is then passed to request_key_and_link() ->
construct_alloc_key().
* Concurrently to that, a second task similarly makes a DNS query for
"abcdef." and its result gets inserted into the DNS resolver cache.
* Back on the first task, function construct_alloc_key() first runs
__key_link_begin() to determine an assoc_array_edit operation to
insert a new key. Index keys in the array are compared exactly as-is,
using keyring_compare_object(). The operation finds that "abcdef" is
not yet present in the destination keyring.
* Function construct_alloc_key() continues and checks if a given key is
already present on some keyring by again calling
search_process_keyrings_rcu(). This search is done using
dns_resolver_cmp() and "abcdef" gets matched with now present key
"abcdef.".
* The found key is linked on the destination keyring by calling
__key_link() and using the previously calculated assoc_array_edit
operation. This inserts the "abcdef." key in the array but creates
a duplicity because the same index key is already present.
Fix the problem by postponing __key_link_begin() in
construct_alloc_key() until an actual key which should be linked into
the destination keyring is determined.
