SW steering, Refactor to have a device specific STE layer below dr_ste
This series introduces some improvements and refactoring by adding a new layer
below dr_ste to allow support for different devices format.
It adds a struct of device specific callbacks for STE layer below dr_ste.
Each device will implement its HW-specific function, and a common logic
from the DR code will access these functions through the new ste_ctx API.
Connect-X5-style steering format is called STE_v0.
In the next patch series we bring the Connect-X6-style format - STE_v1.

Ever since commit 2a9127fcf2 ("mm: rewrite wait_on_page_bit_common()
logic") we've had some very occasional reports of BUG_ON(PageWriteback)
in write_cache_pages(), which we thought we already fixed in commit
073861ed77 ("mm: fix VM_BUG_ON(PageTail) and BUG_ON(PageWriteback)").
But syzbot just reported another one, even with that commit in place.
And it turns out that there's a simpler way to trigger the BUG_ON() than
the one Hugh found with page re-use. It all boils down to the fact that
the page writeback is ostensibly serialized by the page lock, but that
isn't actually really true.
Yes, the people _setting_ writeback all do so under the page lock, but
the actual clearing of the bit - and waking up any waiters - happens
without any page lock.
This gives us this fairly simple race condition:
CPU1 = end previous writeback
CPU2 = start new writeback under page lock
CPU3 = write_cache_pages()
CPU1 CPU2 CPU3
---- ---- ----
end_page_writeback()
test_clear_page_writeback(page)
... delayed...
lock_page();
set_page_writeback()
unlock_page()
lock_page()
wait_on_page_writeback();
wake_up_page(page, PG_writeback);
.. wakes up CPU3 ..
BUG_ON(PageWriteback(page));
where the BUG_ON() happens because we woke up the PG_writeback bit
becasue of the _previous_ writeback, but a new one had already been
started because the clearing of the bit wasn't actually atomic wrt the
actual wakeup or serialized by the page lock.
The reason this didn't use to happen was that the old logic in waiting
on a page bit would just loop if it ever saw the bit set again.
The nice proper fix would probably be to get rid of the whole "wait for
writeback to clear, and then set it" logic in the writeback path, and
replace it with an atomic "wait-to-set" (ie the same as we have for page
locking: we set the page lock bit with a single "lock_page()", not with
"wait for lock bit to clear and then set it").
However, out current model for writeback is that the waiting for the
writeback bit is done by the generic VFS code (ie write_cache_pages()),
but the actual setting of the writeback bit is done much later by the
filesystem ".writepages()" function.
IOW, to make the writeback bit have that same kind of "wait-to-set"
behavior as we have for page locking, we'd have to change our roughly
~50 different writeback functions. Painful.
Instead, just make "wait_on_page_writeback()" loop on the very unlikely
situation that the PG_writeback bit is still set, basically re-instating
the old behavior. This is very non-optimal in case of contention, but
since we only ever set the bit under the page lock, that situation is
controlled.

This code will leak "map->debugfs_name" because the if statement is
reversed so it only frees NULL pointers instead of non-NULL. In
fact the if statement is not required and should just be removed
because kfree() accepts NULL pointers.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Missing sanitization of rateest userspace string, bug has been
triggered by syzbot, patch from Florian Westphal.
2) Report EOPNOTSUPP on missing set features in nft_dynset, otherwise
error reporting to userspace via EINVAL is misleading since this is
reserved for malformed netlink requests.
3) New binaries with old kernels might silently accept several set
element expressions. New binaries set on the NFT_SET_EXPR and
NFT_DYNSET_F_EXPR flags to request for several expressions per
element, hence old kernels which do not support for this bail out
with EOPNOTSUPP.

====================
net: dsa: lantiq_gswip: two fixes for -net/-stable
While testing the lantiq_gswip driver in OpenWrt at least one board had
a non-working Ethernet port connected to an internal 100Mbit/s PHY22F
GPHY. The problem which could be observed:
- the PHY would detect the link just fine
- ethtool stats would see the TX counter rise
- the RX counter in ethtool was stuck at zero
It turns out that two independent patches are needed to fix this:
- first we need to enable the MII data lines also for internal PHYs
- second we need to program the GSWIP_MII_CFG registers for all ports
except the CPU port
These two patches have also been tested by back-porting them on top of
Linux 5.4.86 in OpenWrt.
Special thanks to Hauke for debugging and brainstorming this on IRC
with me!

There is one GSWIP_MII_CFG register for each switch-port except the CPU
port. The register offset for the first port is 0x0, 0x02 for the
second, 0x04 for the third and so on.
Update the driver to not only restrict the GSWIP_MII_CFG registers to
ports 0, 1 and 5. Handle ports 0..5 instead but skip the CPU port. This
means we are not overwriting the configuration for the third port (port
two since we start counting from zero) with the settings for the sixth
port (with number five) anymore.
The GSWIP_MII_PCDU(p) registers are not updated because there's really
only three (one for each of the following ports: 0, 1, 5).

Enable GSWIP_MII_CFG_EN also for internal PHYs to make traffic flow.
Without this the PHY link is detected properly and ethtool statistics
for TX are increasing but there's no RX traffic coming in.

In lapb_device_event, lapb_devtostruct is called to get a reference to
an object of "struct lapb_cb". lapb_devtostruct increases the refcount
of the object and returns a pointer to it. However, we didn't decrease
the refcount after we finished using the pointer. This patch fixes this
problem.
