The linux/export.h include was introduced in commit 9bcb94c861
("batman-adv: Introduce missing headers for genetlink restructure") to have
access to THIS_MODULE. But with commit 5b20755b77 ("init: move
THIS_MODULE from <linux/export.h> to <linux/init.h>"), it was moved and the
include for export.h is no longer needed.

The batman-adv multicast tracker TVLV handler is registered for the
new batman-adv multicast packet type upon creating a batman-adv interface,
but not unregistered again upon the interface's deletion, leading to a
memory leak.
Fix this memory leak by calling the according TVLV handler unregister
routine for the multicast tracker TVLV upon batman-adv interface
deletion.

When a node which does not have the new batman-adv multicast packet type
capability vanishes then the according, global counter erroneously would
not be reduced in response on other nodes. Which in turn leads to the mesh
never switching back to sending with the new multicast packet type.
Fix this by reducing the according counter when such a node times out.

Correct the PHY loopback bit handling in the ksz8_w_phy_bmcr and
ksz8_r_phy_bmcr functions for KSZ8794 and KSZ8873 variants in the ksz8795
driver. Previously, the code erroneously used Bit 7 of port register 0xD
for both chip variants, which is actually for LED configuration. This
update ensures the correct registers and bits are used for the PHY
loopback feature:
- For KSZ8794: Use 0xF / Bit 7.
- For KSZ8873: Use 0xD / Bit 0.
The lack of loopback support was seen on KSZ8873 system by using
"ethtool -t lanX". After this patch, the ethtool selftest will work,
but only if port is not part of a bridge.

net: phy: generic polarity + LED support for qca808x
This small series add LEDs support for qca808x.
QCA808x apply on PHY reset a strange polarity settings and require
some tweak to apply a more common configuration found on devices.
On adding support for it, it was pointed out that a similar
feature is also being implemented for a marvell PHY where
LED polarity is set per LED (and not global) and also have
a special mode where the LED is tristated.
The first 3 patch are to generalize this as we expect more PHY
in the future to have a similar configuration.
The implementation is extensible to support additional special
mode in the future with minimal changes and don't create regression
on already implemented PHY drivers.

Add LED support for QCA8081 PHY.
Documentation for this LEDs PHY is very scarce even with NDA access
to Documentation for OEMs. Only the blink pattern are documented and are
very confusing most of the time. No documentation is present about
forcing the LED on/off or to always blink.
Those settings were reversed by poking the regs and trying to find the
correct bits to trigger these modes. Some bits mode are not clear and
maybe the documentation option are not 100% correct. For the sake of LED
support the reversed option are enough to add support for current LED
APIs.
Supported HW control modes are:
- tx
- rx
- link_10
- link_100
- link_1000
- link_2500
- half_duplex
- full_duplex
Also add support for LED polarity set to set LED polarity to active
high or low. QSDK sets this value to high by default but PHY reset value
doesn't have this enabled by default.
QSDK also sets 2 additional bits but their usage is not clear, info about
this is added in the header. It was verified that for correct function
of the LED if active high is needed, only BIT 6 is needed.

Add support for PHY LEDs polarity modes. Some PHY require LED to be set

active-low property in DT.
PHY driver needs to declare .led_polarity_set() to configure LED
polarity modes. Function will pass the index with the LED index and a
bitmap with all the required modes to set.
Current supported modes are:
- active-low with the flag PHY_LED_ACTIVE_LOW. LED is set to active-low
to turn it ON.
- inactive-high-impedance with the flag PHY_LED_INACTIVE_HIGH_IMPEDANCE.
LED is set to high impedance to turn it OFF.

A potential string truncation was reported in bnx2x_fill_fw_str(),
when a long bp->fw_ver and a long phy_fw_ver might coexist, but seems
unlikely with real-world hardware.
Use scnprintf() to indicate the intent that truncations are tolerated.
While reading this code, I found a collection of various buffer size
counting issues. None looked like they might lead to a buffer overflow
with current code (the small buffers are 20 bytes and might only ever
consume 10 bytes twice with a trailing %NUL). However, early truncation
(due to a %NUL in the middle of the string) might be happening under
likely rare conditions. Regardless fix the formatters and related
functions:
- Switch from a separate strscpy() to just adding an additional "%s" to
the format string that immediately follows it in bnx2x_fill_fw_str().
- Use sizeof() universally instead of using unbound defines.
- Fix bnx2x_7101_format_ver() and bnx2x_null_format_ver() to report the
number of characters written, not including the trailing %NUL (as
already done with the other firmware formatting functions).
- Require space for at least 1 byte in bnx2x_get_ext_phy_fw_version()
for the trailing %NUL.
- Correct the needed buffer size in bnx2x_3_seq_format_ver().

If more than 16000 inflight AF_UNIX sockets exist and the garbage
collector is not running, unix_(dgram|stream)_sendmsg() call unix_gc().
Also, they wait for unix_gc() to complete.
In unix_gc(), all inflight AF_UNIX sockets are traversed at least once,
and more if they are the GC candidate. Thus, sendmsg() significantly
slows down with too many inflight AF_UNIX sockets.
However, if a process sends data with no AF_UNIX FD, the sendmsg() call
does not need to wait for GC. After this change, only the process that
meets the condition below will be blocked under such a situation.
1) cmsg contains AF_UNIX socket
2) more than 32 AF_UNIX sent by the same user are still inflight
Note that even a sendmsg() call that does not meet the condition but has
AF_UNIX FD will be blocked later in unix_scm_to_skb() by the spinlock,
but we allow that as a bonus for sane users.
The results below are the time spent in unix_dgram_sendmsg() sending 1
byte of data with no FD 4096 times on a host where 32K inflight AF_UNIX
sockets exist.
Without series: the sane sendmsg() needs to wait gc unreasonably.

In unix_gc(), all inflight AF_UNIX sockets are traversed at least once,

There is a small window to invoke multiple unix_gc() instances, which

Make MediaTek MT753x DSA driver enable MediaTek Gigabit PHYs driver to
properly control MT7530 and MT7531 switch PHYs.
A noticeable change is that the behaviour of switchport interfaces going
up-down-up-down is no longer there.
Now, the switch can be used without the PHYs but, at the moment, every
hardware design out there that I have seen uses them. For that, it would
make the most sense to force the selection of MEDIATEK_GE_PHY for the MDIO
interface which currently controls the MT7530 and MT7531 switches.

Even with inplace decompression, sometimes very few temporary buffers
may be still needed for a single decompression shot (e.g. 16 pages for
64k sliding window or 4 pages for 16k sliding window). In low-memory
scenarios, it would be better to try to allocate with GFP_NOWAIT on
readahead first. That can help reduce the time spent on page allocation
under durative memory pressure.
Here are detailed performance numbers under multi-app launch benchmark
workload [1] on ARM64 Android devices (8-core CPU and 8GB of memory)
running a 5.15 LTS kernel with EROFS of 4k pclusters:
+----------------------------------------------+
| LZ4 | vanilla | patched | diff |
|----------------+---------+---------+---------|
| Average (ms) | 3364 | 2684 | -20.21% | [64k sliding window]
|----------------+---------+---------+---------|
| Average (ms) | 2079 | 1610 | -22.56% | [16k sliding window]
+----------------------------------------------+
The total size of system images for 4k pclusters is almost unchanged:
(64k sliding window) 9,117,044 KB
(16k sliding window) 9,113,096 KB
Therefore, in addition to switch the sliding window from 64k to 16k,
after applying this patch, it can eventually save 52.14% (3364 -> 1610)
on average with no memory reservation. That is particularly useful for
embedded devices with limited resources.

Use the device lifecycle managed get function. This helps prevent
mistakes like releasing out of order in cleanup functions and
forgetting to release on error paths.

This value only needs read once. Move that read into the function
that returns the value to keep the logic all in one place. This
also avoids doing this check every time we read in values in
the device update poll worker.
While here, correct this function's error message.
