fa38860c5e nl80211: Fix build with libnl 1.1
Commit 630b3230c8 ('nl80211: Increase
netlink receive buffer size') added unconditional use of
nl_socket_set_buffer_size() which was not included in libnl 1.1. Fix use
of that old version by making this conditional on CONFIG_LIBNL20.

630b3230c8 nl80211: Increase netlink receive buffer size
libnl uses a pretty small buffer (32 kB that gets converted to 64 kB) by
default. It is possible to hit that limit in some cases where operations
are blocked, e.g., with a burst of Deauthentication frames to hostapd
and STA entry deletion. Try to increase the buffer to make this less
likely to occur.

Current mesh code uses ap_max_inactivity as inactivity timer. This patch

If a second scan trigger attempt fails in STA mode, the error path was
supposed to restore the old mode that was in use before changing to STA
mode. However, wpa_driver_nl80211_set_mode() changes drv->nlmode on

d58ade2121 nl80211: Fix compilation with libnl 1.1 and 2.0
Unfortunately, libnl 3.0 has changed the API in a way that is not
backwards compatible by renaming nlmsg_len() to nlmsg_datalen() without
leaving the older nlmsg_len() defined. As such, there does not seem to
be any clean way of using this function without breaking the build with
some libnl versions. For now, replace this call with direct calculation
of the data length since it can be done with a simple one-liner that
compiles with all libnl versions.

4bd7195466 nl80211: Try to unmask 11b rates again on next connection request
It is possible for unmasking of 11b rates to fail if a P2P group is
terminated while the netdev is down (e.g., due to rfkill block). This
could result in the 11b TX rates being left masked for non-P2P
operations. This would be particularly unfortunate for channel 14 use
since OFDM rates are not allowed on channel 14 and only OFDM rates were
configured P2P. This issue showed up, e.g., when running hwsim test case
rfkill_autogo followed by ap_wps_conf_chan14.

It may be possible to allow the failed operation in cfg80211/mac80211,
but it looks better to work around this on wpa_supplicant side as well.

rate unmasking operation had failed.

Suppose there are two APs (AP1 & AP2) and user attempted to connect to
AP2 before the previous connection with AP1 could succeed. Now, if the
connection event comes for the older AP with failed status, we should
just ignore it as the wpa_supplicant state has moved to "ASSOCIATING"
with the new AP (AP2).

This is a similar to the case where a disconnection event is ignored for
a case where local disconnect request can cause the extra event to show
up during the next association process following that command.

This reverts commit 851b0c5581.

The kernel now has full support for this (and it is turned off
by default for hwsim) so wpa_supplicant should really go back
to autodetecting this so clients don't have to figure out what
to do.

Also add a debug message stating that P2P_DEVICE support is used.

01b3bbfc66 test: Remove driver_test.c
The driver_test.c driver wrapper (-Dtest in wpa_supplicant and
driver=test in hostapd) was previously used for testing without real
Wi-Fi hardware. mac80211_hwsim-based tests have practically replaced all
these needs and there has been no improvements or use for driver_test.c
in a long while. Because of this, there has not really been any effort
to maintain this older test tool and no justification to change this
either. Remove the obsoleted test mechanism to clean up the repository.

3e0272ca00 nl80211: Re-read MAC address on RTM_NEWLINK
Commit 97279d8d (after hostap-2.0) dropped frame events from foreign
addresses. Unfortunately this commit did not handle the case where the
interface's MAC address might be changed externally, which other
wpa_supplicant code already handled. This causes the driver to reject
any MLME event because the address from the event doesn't match the
stale address in the driver data.

Changing an interface's MAC address requires that the interface be
down, the change made, and then the interface brought back up. This
triggers an RTM_NEWLINK event which driver_nl80211.c can use to
re-read the MAC address of the interface.

b497a21267 nl80211: Ignore auth/assoc events when testing driver-SME
Previously, extra connect/roam events were ignored when user space SME
was used to avoid confusing double events for association. However,
there was no matching code for ignoring auth/assoc events when using
driver SME. Such events would not normally show up since the driver SME
case would not generated them. However, when testing forced connect
command with force_connect_cmd=1 driver param, these events are
indicated.

Ignore the extra events in testing cases to make the hwsim test cases
match more closely the real code path for driver SME. In addition, this
resolves some test case failures where double association event could
end up causing a failure, e.g., when doing PMKSA caching in
pmksa_cache_oppurtunistic_connect.
