2049a875bc WNM: Additional BSS Transition Management capability
Add some more functionality for BSS Transition Management:
- advertise support for BSS Transition Management in extended
  capabilities element
- add hostapd.conf parameter bss_transition=1 for enabling support
  for BSS Transition Management
- add "hostapd_cli disassoc_imminent <STA> <num TBTTs>" for sending
  disassociation imminent notifications for testing purposes
- wpa_supplicant: trigger a new scan to find another BSS if the
  current AP indicates disassociation imminent (TODO: the old AP needs
  to be marked to use lower priority to avoid re-selecting it)

a5e1eb2092 nl80211: Run TKIP countermeasures in correct hostapd_data context
hostapd can run with different VIF when using nl80211. Events about MIC
failures have to be processed in context of the VIF which received it
and not in context of the primary VIF. Otherwise the station belonging
to this VIF may not be found in the primary VIF station hash and
therefore no countermeasures are started or the countermeasures are
started for the wrong VIF.

27c77751f7 WNM: Fix BSS Transition Management Request processing
The WNM-Sleep Mode handler took over WNM Action frame processing without
addressing the previously implemented WNM handler. Fix this by moving
the BSs Transition Management processing into wnm_sta.c to share a
single handler function for WNM Action frames.

3ab35a6603 Extend EAPOL frames processing workaround for roaming cases
Commit 1ff733383f added a mechanism to
work around issues due to association events and EAPOL RX events being
getting reordered. However, this applied only for the case where
wpa_supplicant is not in associated state. The same issue can happen in
roaming case with drivers that perform BSS selection internally (or in
firmware). Handle that case similarly by delaying received EAPOL frame
processing if the source address of the EAPOL frame does not match the
current BSSID.

Since wired IEEE 802.1X do not have BSSID, make this additional
workaround conditional on BSSID match having been observed during the
previous association.

This fixes issues where the initial EAPOL frame after reassociation was
either dropped (e.g., due to replay counter not increasing) or replied
to with incorrect destination address (the BSSID of the old AP). This
can result in significantly more robust roaming behavior with drivers
that do not use wpa_supplicant for BSS selection.

318e772ad1 WPS: Update configuration file after re-enabling networks
Network blocks are disabled during a WPS provisioning step and 10
seconds after this to allow the newly provisioned network to be
selected. The disabled=1 flag gets written to the configuration file
when the credential is added since it happens during this process.
Update the file again after the networks have been re-enabled to avoid
leaving the configuration file into state that is not consistent with
the running configuration.

6fbcbc07e4 WPS: Optimize post-WPS scan even if EAP-Failure is not received
Commit 17a4734dc4 shall optimize the
post-WPS scan based on the channel used during the provisioning only
when the EAP-Failure frame is received. In cases where the EAP-Failure
frame is missed, this optimization shall not happen resulting in the
scan in all the channels thus consuming more time for the connection.
This commit enhances this by storing the requisite information after
the M8 frame is received.

f1b44874c2 Fix initialization of ap_table_{max_size,expiration_time}
The config says that the default for ap_table_max_size is 255 and the
default for ap_table_expiration_time is 60. But the code doesn't reflect
the default values mentioned in the sample config file.

These variables completely disable the code for Overlapping Legacy BSS
Condition by default when they are not correctly initialized. WFA
certification requires this feature and therefore an AP would have
failed the certification process unless they were initialized manually
using the configuration file.

5bbf590a58 hostapd: Android: Force group access to ctrl_iface directory
Same fix as d49ea68284 in
wpa_supplicant.

From original commit:

wpa_supplicant is started from /init.*.rc on Android and that seems
to be using umask 0077 which would leave the control interface
directory without group access. This breaks things since Wi-Fi
framework assumes that this directory can be accessed by other
applications in the wifi group. Fix this by adding group access even
if umask value would prevent this.
