The driver reads xtal_calib from NVM file, but actually never uses it.

fw_running assumes that memory can be retrieved only after alive.
This assumption is no longer true as we support dump before alive.
To avoid invalid access to the NIC, check that STATUS_DEVICE_ENABLED
bit in trans status is set before dumping instead of the prior check.

These flags are not needed on 6 GHz channels, and anyway they were set
incorrectly.
This in turn resulted in alternating channel flags, preventing reg domain
rules to be merged together, so cfg80211 couldn't even send them to the
user space, as the regulatory domain was too large.
Fix it.

another active interface (e.g. associated client). Allow
the code that apply those limitations to run on BSS as well.
Also forbid uAPSD if we have an IBSS or NAN interface in

Since we are now forbidding uAPSD in any concurrency
scenario, we don't need to check the number of PHY

The logic here is rather convoluted - we cannot get here with
lq_sta being NULL as mac80211 will (no longer) call us like
that, and since I removed the rate_control_send_low() call in
this function there's no longer any point in setting priv_sta
to NULL either.
So the only thing that remains to check is if we have actually
initialized our lq_sta->drv pointer, and exit if we didn't in
which case we'll use the data mac80211 already set up for the
low rate usage.

Instead of passing the full TPE elements, in all their glory
and mixed up data formats for HE backward compatibility, parse
them fully into the right values, and pass that to the drivers.
Also introduce proper validation already in mac80211, so that
drivers don't need to do it, and parse the EHT portions.
The code now passes the values in the right order according to
the channel used by an interface, which could also be a subset
of the data advertised by the AP, if we couldn't connect with
the full bandwidth (for whatever reason.)
Also add kunit tests for the more complicated bits of it.

The chanctx can be shared, but it seems like the TPE values for
this vif should only reflect the channel that the vif uses, which
is captured in bss_conf->chanreq.oper rather than the chanctx.
Use that when calculating defaults, a similar issue is where the

The define IEEE80211_MAX_NUM_PWR_LEVEL doesn't make much
sense. Yes, that table has a maximum value of 8, and the
table will actually remain that way, but EHT introduced
a way to encode more levels for 320 MHz channels.
Remove IEEE80211_MAX_NUM_PWR_LEVEL and, for ath11k being

sense since it cannot support 320 MHz channels.

When changing the interface type we also need to update the bss_num, the
driver private data is searched based on a unique (bss_type, bss_num)
tuple, therefore every time bss_type changes, bss_num must also change.
This fixes for example an issue in which, after the mode changed, a
wireless scan on the changed interface would not finish, leading to
repeated -EBUSY messages to userspace when other scan requests were
sent.

The default netdev interface exposed by WILC1000 is registered at probe,
but the chip mac address is not known until ndo_open, which will load and
start chip firmware and then retrieve stored MAC address from it. As a
consequence, the interface has uninitialized value (00:00:00:00:00) until a
user brings up the interface.
Fix MAC address at probe by setting the following steps:
- at probe, read MAC address directly from fuse
- whenever a new netdevice is created, apply saved mac address (which can
be a user-provided address, or the eFuse Mac address if no address has
been passed by user)
- whenever an interface is brought up for the first time (and so the
firmware is loaded and started), enforce netdevice mac address to the
chip (in case user has changed it)

In order to be able to read raw registers (eg the nv mac address) in
wilc1000 during probe before the firmware is loaded and running, we need to
run the basic sdio functions initialization, but then we also need to
properly deinitialize those right after, to preserve the current driver
behavior (keeping the chip idle/unconfigured until the corresponding
interface is brought up). Calling wilc_sdio_deinit in its current form is
not enough because it merely resets an internal flag.
Implement a deinit sequence which symmetrically reset all steps performed
in wilc_sdio_init (only for parts activating/deactivating features, for the
sake of simplicity, let's ignore blocks size configuration reset)

SDIO/SPI probes functions automatically add a default wlan interface on top
of registered wiphy, through wilc_cfg80211_init which in turn calls
wilc_netdev_ifc_init. However, bus is still not fully initialized when we
register corresponding net device (for example we still miss some private
driver data pointers), which for example makes it impossible to
retrieve MAC address from chip (which is supposed to be set on net device
before its registration) before registering net device. More generally, net
device registration should not be done until driver has fully initialized
everything and is ready to handle any operation on the net device.
Prevent net device from being registered so early by doing it at the end of
probe functions. Apply this logic to both sdio and spi buses.

wireless-next patches for v6.10
The third, and most likely the last, "new features" pull request for

we disabled Wireless Extensions just like with iwlwifi earlier. Wi-Fi
7 devices will not support Wireless Extensions (WEXT) anymore so if
someone is still using the legacy WEXT interface it's time to switch
to nl80211 now!
We merged wireless into wireless-next as we decided not to send a
wireless pull request to v6.9 this late in the cycle. Also an
immutable branch with MHI subsystem was merged to get ath11k and
ath12k hibernation working.

* ieee80211-freq-limit Device Tree property support
ath10k
* firmware-name Device Tree property support

netdevsim: add NAPI support
Add NAPI support to netdevsim and register its Rx queues with NAPI
instances. Then add a selftest using the new netdev Python selftest
infra to exercise the existing Netdev Netlink API, specifically the
queue-get API.
This expands test coverage and further fleshes out netdevsim as a test
device. It's still my goal to make it useful for testing things like
flow steering and ZC Rx.

Add a selftest for netdev generic netlink. For now there is only a
single test that exercises the `queue-get` API.
The test works with netdevsim by default or with a real device by
setting NETIF.
Add a timeout param to cmd() since ethtool -L can take a long time on
real devices.

Add NAPI support to netdevim, similar to veth.
* Add a nsim_rq rx queue structure to hold a NAPI instance and a skb
queue.
* During xmit, store the skb in the peer skb queue and schedule NAPI.
* During napi_poll(), drain the skb queue and pass up the stack.
* Add assoc between rxq and NAPI instance using netif_queue_set_napi().

Run tools/testing/selftest/net/csum.c as part of drv-net.
This binary covers multiple scenarios, based on arguments given,
for both IPv4 and IPv6:
- Accept UDP correct checksum
- Detect UDP invalid checksum
- Accept TCP correct checksum
- Detect TCP invalid checksum
- Transmit UDP: basic checksum offload
- Transmit UDP: zero checksum conversion
The test direction is reversed between receive and transmit tests, so
that the NIC under test is always the local machine.
In total this adds up to 12 testcases, with more to follow. For
conciseness, I replaced individual functions with a function factory.
Also detect hardware offload feature availability using Ethtool
netlink and skip tests when either feature is off. This need may be
common for offload feature tests and eventually deserving of a thin
wrapper in lib.py.
Missing are the PF_PACKET based send tests ('-P'). These use
virtio_net_hdr to program hardware checksum offload. Which requires
looking up the local MAC address and (harder) the MAC of the next hop.
I'll have to give it some though how to do that robustly and where
that code would belong.
Tested:
make -C tools/testing/selftests/ \
TARGETS="drivers/net drivers/net/hw" \
install INSTALL_PATH=/tmp/ksft
cd /tmp/ksft
sudo NETIF=ens4 REMOTE_TYPE=ssh \
REMOTE_ARGS="root@10.40.0.2" \
LOCAL_V4="10.40.0.1" \
REMOTE_V4="10.40.0.2" \

route_dumpit() already relies on RCU, RTNL is not needed.
Also change return value at the end of a dump.
This allows NLMSG_DONE to be appended to the current
skb at the end of a dump, saving a couple of recvmsg()
system calls.

Let's make all IPVS sysctls writtable even when
network namespace is owned by non-initial user namespace.
Let's make a few sysctls to be read-only for non-privileged users:
- sync_qlen_max
- sync_sock_size
- run_estimation
- est_cpulist
- est_nice
I'm trying to be conservative with this to prevent
introducing any security issues in there. Maybe,
we can allow more sysctls to be writable, but let's
do this on-demand and when we see real use-case.
This patch is motivated by user request in the LXC
project [1]. Having this can help with running some
Kubernetes [2] or Docker Swarm [3] workloads inside the system
containers.
