When a new station is added to AP/GO interfaces the default behaviour
is for it to be added authenticated and associated, due to backwards
compatibility. To prevent that, the driver must be able to do that
(setting the NL80211_FEATURE_FULL_AP_CLIENT_STATE feature flag) and
userspace must set the flag mask to auth|assoc and clear the set.
Handle this quirk in the API entirely in nl80211, and always push the
full flags to the drivers. NL80211_FEATURE_FULL_AP_CLIENT_STATE is
still required for userspace to be allowed to set the mask including
those bits, but after checking that add both flags to the mask and
set in case userspace didn't set them otherwise.
This obsoletes the mac80211 code handling this difference, no other
driver is currently using these flags.

add ieee80211_iter_keys_rcu() to iterate over uploaded
keys in atomic context (when rcu is locked)
The station removal code removes the keys only after
calling synchronize_net(), so it's not safe to iterate
the keys at this point (and postponing the actual key
deletion with call_rcu() might result in some
badly-ordered ops calls).
Add a flag to indicate a station is being removed,
and skip the configured keys if it's set.

This can happen when the driver needs to send less frames
than expected and then needs to close the SP.
Mac80211 still needs to set the more_data properly based
on its buffer state (ps_tx_buffer and buffered frames on
other TIDs).
To that end, refactor the code that delivers frames upon
uAPSD trigger frames to be able to get only the more_data
bit without actually delivering those frames in case the
driver is just asking to set a NDP with EOSP and MORE_DATA
bit properly set.

This really should never happen except very early in the process
of bringing up a new driver, at which point you'll have to add

This indicates a driver key selection issue, but even then there's
no point in printing it all the time, so ratelimit it. Also remove
the priv pointer from it -- people debugging will only have a single
device anyway and it's useless as anything but a cookie.

In the last change here, I neglected to update the cookie in one code
path: when a mgmt-tx has no real cookie sent to userspace as it doesn't
wait for a response, but is off-channel. The original code used the SKB
pointer as the cookie and always assigned the cookie to the TX SKB in
ieee80211_start_roc_work(), but my change turned this around and made
the code rely on a valid cookie being passed in.
Unfortunately, the off-channel no-wait TX path wasn't assigning one at
all, resulting in an uninitialized stack value being used. This wasn't
handed back to userspace as a cookie (since in the no-wait case there
isn't a cookie), but it was tested for non-zero to distinguish between
mgmt-tx and off-channel.
Fix this by assigning a dummy non-zero cookie unconditionally, and get
rid of a misleading comment and some dead code while at it. I'll clean
up the ACK SKB handling separately later.

DFS channels should not be actively scanned as we can't be sure
if we are allowed or not.
If the current channel is in the DFS band, active scan might be
performed after CSA, but we have no guarantee about other channels,
therefore it is safer to prevent active scanning at all.

However, p2p device is being torn down when stopped,

Commit 09605cc12c078306 ("net ipv4: use preferred log methods") replaced
a few calls of pr_cont() after a console print without a trailing
newline by pr_info(), causing lines to be split during IP
autoconfiguration, like:
.
,
OK
IP-Config: Got DHCP answer from 192.168.97.254,
my address is 192.168.97.44
Convert these back to using pr_cont(), so it prints again:
., OK
IP-Config: Got DHCP answer from 192.168.97.254, my address is 192.168.97.44
Absorb the printing of "my address ..." into the previous call to
pr_info(), as there's no reason to use a continuation there.
Convert one more pr_info() to print nameservers while we're at it.

After the introduction of the switch gpio reset API, I'm getting
build errors in configurations that disable CONFIG_GPIOLIB:
net/dsa/dsa.c:783:16: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration]
The reason is that linux/gpio/consumer.h is not automatically
included without gpiolib support. This adds an explicit #include
statement to make it compile in all configurations. The reset
functionality will not work without gpiolib, which is what you
get when disabling the feature.
As far as I can tell, gpiolib is supported on all architectures
on which you can have DSA at the moment.

Add the helper pimsm_enabled() which replaces the old CONFIG_IP_PIMSM

Use a single if defined(CONFIG_IP_PIMSM_V1) || defined(CONFIG_IP_PIMSM_V2)
for the pim-sm shared code. This is okay w.r.t IGMPMSG_WHOLEPKT because
only a VIFF_REGISTER device can send such packet, and it can't be

In order to enable advertising with privacy enabled, SMP has to be
registered in order to generate new RPA. During power on, it will be
registered at the very end which is the reason why advertising is not
enabled and it's not possible to enable it anymore due to mismatch
between hci_dev settings and actual controller state.
This fixes this problem by moving SMP registration earlier, just after
controller is powered (which is ok, because LE SMP will be already able
to decide on identity address to be used), but before advertising is
enabled.

In our effort to have less code and include dependencies between
entities such as node, link and bearer, we try to narrow down
the exposed interface towards the node as much as possible.
In this commit, we move the definition of struct tipc_node, along
with many of its associated function declarations, from node.h to
node.c. We also move some function definitions from link.c and
name_distr.c to node.c, since they access fields in struct tipc_node
that should not be externally visible. The moved functions are renamed
according to new location, and made static whenever possible.
