Station structure is considered as not uploaded
(to driver) until drv_sta_state() finishes. This
call is however done after the structure is
attached to mac80211 internal lists and hashes.
This means mac80211 can lookup (and use) station
structure before it is uploaded to a driver.
If this happens (structure exists, but
sta->uploaded is false) fast_tx path can still be
taken. Deep in the fastpath call the sta->uploaded
is checked against to derive "pubsta" argument for
ieee80211_get_txq(). If sta->uploaded is false
(and sta is actually non-NULL) ieee80211_get_txq()
effectively downgraded to vif->txq.
At first glance this may look innocent but coerces
mac80211 into a state that is almost guaranteed
(codel may drop offending skb) to crash because a
station-oriented skb gets queued up on
vif-oriented txq. The ieee80211_tx_dequeue() ends
up looking at info->control.flags and tries to use
txq->sta which in the fail case is NULL.
It's probably pointless to pretend one can
downgrade skb from sta-txq to vif-txq.
Since downgrading unicast traffic to vif->txq must
not be done there's no txq to put a frame on if
sta->uploaded is false. Therefore the code is made
to fall back to regular tx() op path if the
described condition is hit.
Only drivers using wake_tx_queue were affected.

Recently we started using ipmr with thousands of entries and easily hit
soft lockups on smaller devices. The reason is that the hash function
uses the high order bits from the src and dst, but those don't change in
many common cases, also the hash table is only 64 elements so with
thousands it doesn't scale at all.
This patch migrates the hash table to rhashtable, and in particular the
rhl interface which allows for duplicate elements to be chained because
of the MFC_PROXY support (*,G; *,*,oif cases) which allows for multiple
duplicate entries to be added with different interfaces (IMO wrong, but
it's been in for a long time).
And here are some results from tests I've run in a VM:
mr_table size (default, allocated for all namespaces):
Before After
49304 bytes 2400 bytes
Add 65000 routes (the diff is much larger on smaller devices):
Before After
1m42s 58s
Forwarding 256 byte packets with 65000 routes (test done in a VM):
Before After

If a file is renamed, but stays in the same directory, we will still receive
2 change_info4 structures describing the change to that directory, but we
only want to apply it once.

We don't want to invalidate the directory attribute and data cache unless we
know that a file was created, or the change attribute differs from the one
in our cache.

Remove code that's no longer needed. It used to serve a purpose, which was
to fix a link-related bug. For a while now, the NIC firmware has had a
more elegant fix for that bug.

rtm_table is an 8-bit field while table ids are allowed up to u32. Commit
709772e6e0 ("net: Fix routing tables with id > 255 for legacy software")
added the preference to set rtm_table in dumps to RT_TABLE_COMPAT if the
table id is > 255. The table id returned on get route requests should do
the same.

Commit 6ffe1c4cd0 ("net: qcom/emac: fix of_node and phydev leaks")
fixed the problem with reference leaks on phydev, but the fix is
device-tree specific. When the driver unloads, the reference is
dropped only on DT systems.
Instead, it's cleaner if up grab an reference on ACPI systems.
When the driver unloads, we can drop the reference without having
to check whether we're on a DT system.

net: mdio-gpio: Use modern GPIO helpers
This patch series modernizes the mdio-gpio and makes it switch to the
latest and greatest API for manipulating GPIO lines, thus allowing
some simplifications in the driver.

gpiod functions support handling low-active pins, so we can move

Using gpiod functions lets us use functionality which is not available
with gpio functions.
There is no gpiod function to match devm_gpio_request_one, so leave it
in place and use gpio_to_desc() to convert absolute pin numbers to gpio
descriptors.

On AMD's SB800 and upwards, the SMBus is shared with the Integrated
Micro Controller (IMC).
The platform provides a hardware semaphore to avoid race conditions
among them. (Check page 288 of the SB800-Series Southbridges Register
Reference Guide http://support.amd.com/TechDocs/45482.pdf)
Without this patch, many access to the SMBus end with an invalid
transaction or even with the bus stalled.
