Use os_exec() to run the action script operations to avoid undesired

unsanitized data which is not suitable for system() use. (CVE-2014-3686)

This allows cases where neither 80 MHz segment requires DFS to be
configured. DFS CAC operation itself does not yet support 80+80, though,
so if either segment requires DFS, the AP cannot be brought up.

This extends the "XOR t" operation in aes_wrap() and aes_unwrap() to

which was the previous limit.

BoringSSL is Google's cleanup of OpenSSL and an attempt to unify
Chromium, Android and internal codebases around a single OpenSSL.
As part of moving Android to BoringSSL, the wpa_supplicant maintainers
in Android requested that I upstream the change. I've worked to reduce
the size of the patch a lot but I'm afraid that it still contains a
number of #ifdefs.

Commit 86bd36f0d5 ("Add generic
mechanism for adding vendor elements into frames") has a minor bug
where it miscalculates the length of memory to move using
os_memmove. If multiple vendor elements are specified then this can
lead to out of bounds memory accesses.
This patch fixes this by calculating the correct length of remaining
data to shift down in the information element.

If the first entry in the PMKSA cache did not match the station's MAC
address, an infinite loop could be reached in pmksa_cache_get_okc() when

This would only happen if OKC is enabled (okc=1 included in the

This verifies that hostapd uses Session-Timeout value from Access-Accept

Previously, WPA/WPA2 case ended up using the hardcoded
dot11RSNAConfigPMKLifetime (43200 seconds) for PMKSA cache entries
instead of using the Session-Timeout value from the RADIUS server (if
included in Access-Accept). Store a copy of the Session-Timeout value
and use it instead of the default value so that WPA/WPA2 cases get the
proper timeout similarly to non-WPA/WPA2 cases.

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.

Previously, the case of non-netdev P2P management device ended up
pulling in both the main interface (e.g., wlan0) and P2P Device
interface (from command line -m argument) as configuration. Similarly,
the main interface ended up included both configuration files. This is
not really helpful for various use cases, e.g., when permanent P2P group
information is stored in the P2P Devince interface, but it gets
duplicated in the main station interface configuration.
Clean this up by changing the -m<file> argument to replace, not
concatenate, configuration information. In other words, the main station
interface will not read this configuration and the P2P Device interface
(non-netdev) does not read parameters from the station interface
configuration file.

Older mac80211 implementations did not set the link identifier
appropriately, resulting in an incorrect teardown packet being sent the
peer. wpa_supplicant adds the FTE containing the MIC field calculated
using the correct link-identifier. This causes a MIC failure on the
other side and the teardown is discarded. Verify this case is fixed by
newer kernel and wpa_supplicant code.
