Vlad Buslov says:
====================
net: Allow offloading of UDP NEW connections via act_ct
Currently only bidirectional established connections can be offloaded
via act_ct. Such approach allows to hardcode a lot of assumptions into
act_ct, flow_table and flow_offload intermediate layer codes. In order
to enabled offloading of unidirectional UDP NEW connections start with
incrementally changing the following assumptions:
- Drivers assume that only established connections are offloaded and
don't support updating existing connections. Extract ctinfo from meta
action cookie and refuse offloading of new connections in the drivers.
- Fix flow_table offload fixup algorithm to calculate flow timeout
according to current connection state instead of hardcoded
"established" value.
- Add new flow_table flow flag that designates bidirectional connections
instead of assuming it and hardcoding hardware offload of every flow
in both directions.
- Add new flow_table flow flag that designates connections that are
offloaded to hardware as "established" instead of assuming it. This
allows some optimizations in act_ct and prevents spamming the
flow_table workqueue with redundant tasks.
With all the necessary infrastructure in place modify act_ct to offload
UDP NEW as unidirectional connection. Pass reply direction traffic to CT
and promote connection to bidirectional when UDP connection state
changes to "assured". Rely on refresh mechanism to propagate connection
state change to supporting drivers.
Note that early drop algorithm that is designed to free up some space in
connection tracking table when it becomes full (by randomly deleting up
to 5% of non-established connections) currently ignores connections
marked as "offloaded". Now, with UDP NEW connections becoming
"offloaded" it could allow malicious user to perform DoS attack by
filling the table with non-droppable UDP NEW connections by sending just
one packet in single direction. To prevent such scenario change early
drop algorithm to also consider "offloaded" connections for deletion.

net/sched: act_ct: offload UDP NEW connections
Modify the offload algorithm of UDP connections to the following:
- Offload NEW connection as unidirectional.
- When connection state changes to ESTABLISHED also update the hardware
flow. However, in order to prevent act_ct from spamming offload add wq for
every packet coming in reply direction in this state verify whether
connection has already been updated to ESTABLISHED in the drivers. If that
it the case, then skip flow_table and let conntrack handle such packets
which will also allow conntrack to potentially promote the connection to
ASSURED.
- When connection state changes to ASSURED set the flow_table flow
NF_FLOW_HW_BIDIRECTIONAL flag which will cause refresh mechanism to offload
the reply direction.
All other protocols have their offload algorithm preserved and are always
offloaded as bidirectional.
Note that this change tries to minimize the load on flow_table add
workqueue. First, it tracks the last ctinfo that was offloaded by using new
flow 'NF_FLOW_HW_ESTABLISHED' flag and doesn't schedule the refresh for
reply direction packets when the offloads have already been updated with
current ctinfo. Second, when 'add' task executes on workqueue it always
update the offload with current flow state (by checking 'bidirectional'
flow flag and obtaining actual ctinfo/cookie through meta action instead of
caching any of these from the moment of scheduling the 'add' work)
preventing the need from scheduling more updates if state changed
concurrently while the 'add' work was pending on workqueue.

468ba54bd616 ("fec: convert
to gpio descriptor") clashed with gpiolib applying the same quirk to the
reset GPIO polarity (introduced in commit
b02c85c9458c). This results in
the reset line being left active/device being left in reset state when
reset line is "active low".
Remove handling of 'phy-reset-active-high' property from the driver and
rely on gpiolib to apply needed adjustments to avoid ending up with the
double inversion/flipped logic.

net: fec: restore handling of PHY reset line as optional
Conversion of the driver to gpiod API done in
468ba54bd616 ("fec:
convert to gpio descriptor") incorrectly made reset line mandatory and
resulted in aborting driver probe in cases where reset line was not
specified (note: this way of specifying PHY reset line is actually
deprecated).
Switch to using devm_gpiod_get_optional() and skip manipulating reset
line if it can not be located.

Pull s390 fixes from Heiko Carstens:
- With CONFIG_VMAP_STACK enabled it is not possible to load the s390
specific diag288_wdt watchdog module. The reason is that a pointer to
a string is passed to an inline assembly; this string however is
located on the stack, while the instruction within the inline
assembly expects a physicial address. Fix this by copying the string
to a kmalloc'ed buffer.
- The diag288_wdt watchdog module does not indicate that it accesses
memory from an inline assembly, which it does. Add "memory" to the
clobber list to prevent the compiler from optimizing code incorrectly
away.
- Pass size of the uncompressed kernel image to __decompress() call.
Otherwise the kernel image decompressor may corrupt/overwrite an
initrd. This was reported to happen on s390 after commit
2aa14b1ab2c4
("zstd: import usptream v1.5.2").

The code expect the PHY to be in power down which is only true after reset.
Allow changes of the SGMII parameters more than once.
Only power down when reconfiguring to avoid bouncing the link when there's
no reason to - based on code from Russell King.
There are cases when the SGMII_PHYA_PWD register contains 0x9 which
prevents SGMII from working. The SGMII still shows link but no traffic
can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
taken from a good working state of the SGMII interface.
