When using the wext compatibility code in cfg80211, part of the IEs
can be truncated if the passed user buffer is large enough for part
of the BSS but not large enough for all of the IEs. This can cause
an EAP network to show up as a PSK network.
Always return -E2BIG in this case to avoid truncating data.
Since this changes the control flow, use an on-stack variable for
a small buffer instead of allocating it.

Revert commit ad38bfc916 ("mac80211: Tx frame latency statistics")
(along with some follow-up fixes).
This code turned out not to be as useful in the current form as we
thought, and we've internally hacked it up more, but that's not
very suitable for upstream (for now), and we might just do that
with tracing instead.
Therefore, for now at least, remove this code. We might also need
to use the skb->tstamp field for the TCP performance issue, which
is more important than the debugging.

Both wpa_supplicant and mac80211 have and inactivity timer. By default
wpa_supplicant will be timed out in 5 minutes and mac80211's it is 30
minutes. If wpa_supplicant uses a longer timer than mac80211, it will
get unexpected disconnection by mac80211.
Using 0xffffffff instead as the configured value could solve this w/o
changing the code, but due to integer overflow in the expression used
this doesn't work. The expression is:
(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)
On 32bit system, the right side would overflow and be a very small
value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large,
causing unexpectedly early disconnections.
Instead allow disabling the inactivity timer to avoid this situation,
by passing the (previously invalid and useless) value 0.

Due to the checks in get_hwsim_data_ref_from_addr, wmediumd

When a fully converted cfg80211 driver needs cfg80211-wext for
userspace API purposes, the symbols need not be exported. When
other drivers (orinoco/hermes or ipw2200) are enabled, they do
need the symbols exported as they use them directly.
Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig
symbol (instead of just CFG80211_WEXT) and export the functions
only if requested - this saves about 1/2k due to the size of
EXPORT_SYMBOL() itself.

When changing AP SMPS, we need to look up all the stations
for this interface, so there's no reason to iterate over
hash chains rather than doing the simpler iteration over
the station list.

Since multicast addresses don't exist as stations, don't attempt
to look them up in the hashtable on TX.

vlan add/deletes are not notified to userspace today. This patch adds
vlan info to bridge newlink/dellink notifications generated from the
bridge driver. Notifications use the RTEXT_FILTER_BRVLAN_COMPRESSED
flag to compress vlans into ranges whereever applicable.
The size calculations does not take ranges into account for
simplicity. This has the potential for allocating a larger skb than
required.
There is an existing inconsistency with bridge NEWLINK and DELLINK
change notifications. Both generate NEWLINK notifications. Since its
always a NEWLINK notification, this patch includes all vlans the port
belongs to in the notification. The NEWLINK and DELLINK request
messages however only include the vlans to be added and deleted.

Although it is clear that textsearch state is intentionally passed to
skb_find_text() as uninitialized argument, it was never used by the

An error return from __vnet_tx_trigger() sets the TX descriptor to
VIO_DESC_FREE while leaving port->tx_bufs[txi].skb set. This leads
to a BUG_ON() the next time this descriptor is used.
This patch frees the pending skb when getting a trigger error to
match the VIO_DESC_FREE state.
