On boards with LAN9514 and no preconfigured MAC address we don't get an
ip address from DHCP after commit a049a30fc27c ("net: usb: Correct PHY handling
of smsc95xx") anymore. Adding an explicit reset before starting the phy
fixes the issue.

The driver neglects to check the result of platform_get_irq_optional()'s
call and blithely passes the negative error codes to devm_request_irq()
(which takes *unsigned* IRQ #), causing it to fail with -EINVAL.
Stop calling devm_request_irq() with the invalid IRQ #s.

- Update drivers to use common helpers for GUIDs, pkeys, bitmaps,
memset_startat, and others
- General code cleanups from bots
- Simplify some of the rxe pool code in preparation for a larger
rework
- Clean out old stuff from hns, including all support for hip06

Since commit b39648079db4 ("net: mscc: ocelot: disable flow control on
NPI interface"), flow control should be disabled on the DSA CPU port
when used in NPI mode.
However, the commit blamed in the Fixes: tag below broke this, because
it allowed felix_phylink_mac_link_up() to overwrite SYS_PAUSE_CFG_PAUSE_ENA
for the DSA CPU port.
This issue became noticeable since the device tree update from commit
8fcea7be5736 ("arm64: dts: ls1028a: mark internal links between Felix
and ENETC as capable of flow control").
The solution is to check whether this is the currently configured NPI
port from ocelot_phylink_mac_link_up(), and to not modify the statically
disabled PAUSE frame transmission if it is.
When the port is configured for lossless mode as opposed to tail drop
mode, but the link partner (DSA master) doesn't observe the transmitted
PAUSE frames, the switch termination throughput is much worse, as can be
seen below.

In Linux bonding scenario, one packet is copied to several copies and sent
by all slave device of bond0 in mode 3(broadcast mode). The mode 3 xmit
function bond_xmit_broadcast() only ueses the last slave device's tx result
as the final result. In this case, if the last slave device is down, then
it always return NET_XMIT_DROP, even though the other slave devices xmit
success. It may cause the tx statistics error, and cause the application
(e.g. scp) consider the network is unreachable.
For example, use the following command to configure server A.
echo 3 > /sys/class/net/bond0/bonding/mode
ifconfig bond0 up
ifenslave bond0 eth0 eth1
ifconfig bond0 192.168.1.125
ifconfig eth0 up
ifconfig eth1 down
The slave device eth0 and eth1 are connected to server B(192.168.1.107).
Run the ping 192.168.1.107 -c 3 -i 0.2 command, the following information
is displayed.
PING 192.168.1.107 (192.168.1.107) 56(84) bytes of data.
64 bytes from 192.168.1.107: icmp_seq=1 ttl=64 time=0.077 ms
64 bytes from 192.168.1.107: icmp_seq=2 ttl=64 time=0.056 ms
64 bytes from 192.168.1.107: icmp_seq=3 ttl=64 time=0.051 ms
192.168.1.107 ping statistics
0 packets transmitted, 3 received
Actually, the slave device eth0 of the bond successfully sends three
ICMP packets, but the result shows that 0 packets are transmitted.
Also if we use scp command to get remote files, the command end with the
following printings.
ssh_exchange_identification: read: Connection timed out
So this patch modifies the bond_xmit_broadcast to return NET_XMIT_SUCCESS
if one slave device in the bond sends packets successfully. If all slave
devices send packets fail, the discarded packets stats is increased. The
skb is released when there is no slave device in the bond or the last slave
device is down.

We have seen cases where an endpoint RX completion interrupt arrives
while replenishing for the endpoint is underway. This causes another
instance of replenishing to begin as part of completing the receive
transaction. If this occurs it can lead to transaction corruption.
Use a new flag to ensure only one replenish instance for an endpoint
executes at a time.

Define a new replenish_flags bitmap to contain Boolean flags
associated with an endpoint's replenishing state. Replace the
replenish_enabled field with a flag in that bitmap. This is to
prepare for the next patch, which adds another flag.

In ipa_endpoint_replenish(), if an error occurs when attempting to
replenish a receive buffer, we just quit and try again later. In
that case we increment the backlog count to reflect that the attempt
was unsuccessful. Then, if the add_one flag was true we increment
the backlog again.
This second increment is not included in the backlog local variable
though, and its value determines whether delayed work should be
scheduled. This is a bug.
Fix this by determining whether 1 or 2 should be added to the
backlog before adding it in a atomic_add_return() call.

The bug was found during fuzzing. Stacktrace locates it in
ath5k_eeprom_convert_pcal_info_5111.
When none of the curve is selected in the loop, idx can go
up to AR5K_EEPROM_N_PD_CURVES. The line makes pd out of bound.
pd = &chinfo[pier].pd_curves[idx];
There are many OOB writes using pd later in the code. So I
added a sanity check for idx. Checks for other loops involving
AR5K_EEPROM_N_PD_CURVES are not needed as the loop index is not
used outside the loops.
The patch is NOT tested with real device.
The following is the fuzzing report

Commit b4a0f54156ac ("ath11k: move peer delete after vdev stop of station
for QCA6390 and WCN6855") is to fix firmware crash by changing the WMI
command sequence, but actually skip all the peer delete operation, then
it lead commit 58595c9874c6 ("ath11k: Fixing dangling pointer issue upon
peer delete failure") not take effect, and then happened a use-after-free
warning from KASAN. because the peer->sta is not set to NULL and then used
later.
Change to only skip the WMI_PEER_DELETE_CMDID for QCA6390/WCN6855.

Mask the ECN bits before calling mlx5e_route_lookup_ipv4_get(). The
tunnel key might have the last ECN bit set. This interferes with the
route lookup process as ip_route_output_key_hash() interpretes this bit
specially (to restrict the route scope).
Found by code inspection, compile tested only.

When there is an error in peer create process from
ath11k_peer_find(), the code attempts to handle a fallback
for peer create. When this fallback fails, the driver returns
the fallback return code rather than actual error code
(-ENOENT). So refactor the fallback routine to return
the actual error code.

Currently, ath11k_core_alloc() creates a single thread workqueue.
This workqueue is not detroyed during clean up when ath11k modules
are unloaded from the kernel and is left as it is.
If workqueue is not destroyed, it could lead to kernel
memory scarcity in a longer run. This could affect self and
other drivers workability as well.
Add destroy workqueue in ath11k_core_free().

In function ath10k_wow_convert_8023_to_80211(), it will do memcpy for
the new->pattern, and currently the new->pattern and new->mask is same
with the old, then the memcpy of new->pattern will also overwrite the
old->pattern, because the header format of new->pattern is 802.11,
its length is larger than the old->pattern which is 802.3. Then the
operation of "Copy frame body" will copy a mistake value because the

"The most signigicant change here is the addition of a new cpufreq
'P-state' driver for AMD processors as a better replacement for the
venerable acpi-cpufreq driver.
There are also other cpufreq updates (in the core, intel_pstate, ARM
drivers), PM core updates (mostly related to adding new macros for
declaring PM operations which should make the lives of driver
developers somewhat easier), and a bunch of assorted fixes and
cleanups.
Summary:
- Add new P-state driver for AMD processors (Huang Rui).
- Fix initialization of min and max frequency QoS requests in the
cpufreq core (Rafael Wysocki).
- Fix EPP handling on Alder Lake in intel_pstate (Srinivas
Pandruvada).

- Make cpuidle use default_groups in kobj_type (Greg Kroah-Hartman).
- Fix two comments in cpuidle code (Jason Wang, Yang Li).
- Allow model-specific normal EPB value to be used in the intel_epb
sysfs attribute handling code (Srinivas Pandruvada).
- Simplify locking in pm_runtime_put_suppliers() (Rafael Wysocki).
- Add safety net to supplier device release in the runtime PM core
code (Rafael Wysocki).
- Capture device status before disabling runtime PM for it (Rafael
Wysocki).
- Add new macros for declaring PM operations to allow drivers to
avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
update some drivers to use these macros (Paul Cercueil).
- Allow ACPI hardware signature to be honoured during restore from
hibernation (David Woodhouse).
- Update outdated operating performance points (OPP) documentation
(Tang Yizhou).

Old USB API is prone to uninit value bugs if error handling is not
correct. Let's move atusb to use new USB API to
1) Make code more simple, since new API does not require memory
to be allocates via kmalloc()
2) Defend driver from usb-related uninit value bugs.
3) Make code more modern and simple
This patch removes atusb usb wrappers as Greg suggested [0], this will make
code more obvious and easier to understand over time, and replaces old
API calls with new ones.
Also this patch adds and updates usb related error handling to prevent
possible uninit value bugs in future

So, if dma_set_mask_and_coherent() succeeds, 'pci_using_dac' is known to be
1.
Simplify code and remove some dead code accordingly.

As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.
Moreover, dma_set_mask_and_coherent() returns 0 or -EIO, so the return
code of the function can be used directly.
Finally, inline bnx2x_set_coherency_mask() because it is now only a wrapper
for a single dma_set_mask_and_coherent() call.
Simplify code and remove some dead code accordingly.

So if dma_set_mask_and_coherent() succeeds, 'netdev->features' will have
NETIF_F_HIGHDMA in all cases. Move the assignment of this feature in
be_netdev_init() instead be_probe() which is a much logical place.
