279d859b8f Fix IEEE 802.11r/w compilation error
The hostapd/wpa_supplicant compilation failed with CONFIG_IEEE80211R=y
or CONFIG_IEEE80211W=y option if CONFIG_EAP_PSK and CONFIG_EAP_GPSK are
not used.

9b336bcef0 DragonFly BSD: Fix driver_bsd.c build
Both hostapd/wpa_supplicant compilation fails on DragonFly BSD.

This patch solves this issue.

I have tested only compilation. Not functionality.
Because I don't have any device which can work on DragonFly BSD.

6d6f4bb87f nl80211: Work around mac80211 limitation on (re)auth when authenticated
mac80211 does not currently allow (re)authentication when we are already
authenticated. In order to work around this, force deauthentication if
nl80211 authentication command fails with EALREADY. Unfortunately, the
workaround code in driver_nl80211.c alone is not enough since the
following disconnection event would clear wpa_supplicant authentication
state. To handle this, add some code to restore authentication state
when using userspace SME.

This workaround will hopefully become unnecessary in some point should
mac80211 start accepting new authentication requests even when in
authenticated state.

out automatically which AES extra files need to be included in the

38b462868c Clean up crypto makefile segments
Reorganize the TLS/crypto library segments into a single set of blocks
for each library instead of multiple locations handling library-specific
operations. Group crypto functionality together and get wpa_supplicant
and hostapd Makefile closer to eachother in order to make it easier to
eventually move this into a shared makefile.

f042122a57 Allow the internal DH implementation to be overridden
Crypto library wrappers can now override the internal DH (group 5)
implementation. As a starting point, this is done with OpenSSL. The
new mechanism is currently available only for WPS (i.e., IKEv2 still
depends on the internal DH implementation).

currently do anything with this event apart from showing it in
the debug log.

1066c1ee3c Fix VLAN ID validation check to use the new VLAN ID

accept_mac_file, the assigned vlan_id, not the old sta->vlan_id
(likely zero) needs to be used.

ebf214e670 NSS: Implement TLS PRF using new TLS extractor interface
This allows NSS to be used to derive EAP-TLS/PEAP/TTLS keying material.
NSS requires a patch from
https://bugzilla.mozilla.org/show_bug.cgi?id=507359
to provide the new API. In addition, that patch needs to be modified to
add the 16-bit context length value in SSL_ExportKeyingMaterial() only if
contextlen != 0 in order to match with the EAP-TLS/PEAP/TTLS use cases.
This issue seems to be coming from the unfortunate incompatibility in
draft-ietf-tls-extractor-07.txt (draft-ietf-tls-extractor-00.txt would
have used compatible PRF construction).

At this point, it is unclear how this will be resolved eventually, but
anyway, this shows a mechanism that can be used to implement EAP key
derivation with NSS with a small patch to NSS.

If no BSSes/IBSSes matching the enabled networks are found in the scan
results, IBSS/AP mode network (if configured) can be created in
ap_scan=1 mode instead of requiring ap_scan=2 mode to be used whenever
using IBSS or AP mode.

289ffc2b61 Add preliminary version of NSS TLS/crypto wrapper for wpa_supplicant
This brings in the first step in adding support for using NSS
(Mozilla Network Security Services) as the crypto and TLS library
with wpa_supplicant. This version is able to run through EAP-PEAP
and EAP-TTLS authentication, but does not yet implement any
certificate/private key configuration. In addition, this does not
implement proper key fetching functions either, so the end result
is not really of much use in real world yet.

c140a22858 Remove the STA entry on reassociation to clear STA PS state
hostapd needs to remove the old STA entry if it exists when processing
reassociation back to the same AP. This removes the potentially PS
buffered frames and allows association parameters to be updated with
mac80211.

d723bab4b3 Revert "nl80211: Share the same routine for NL80211_ATTR_KEY_CIPHER setup"
This reverts commit 5aa9cb5cca.

The nested key attribute is using different attribute values
(NL80211_KEY_* vs. NL80211_ATTR_KEY_*), so cannot share the same routine
for these purposes..

0194fedb46 driver_nl80211: Fix MLME key settings for static WEP
Current wpa_supplicant has a bug with WEP keys, it adds a zero-length
sequence counter field to netlink which the kernel doesn't accept.

Additionally, the kernel API slightly changed to accept keys only when
connected, so we need to send it the keys after that. For that to work
with shared key authentication, we also include the default WEP TX key
in the authentication command.

To upload the keys properly _after_ associating, add a new flag
WPA_DRIVER_FLAGS_SET_KEYS_AFTER_ASSOC_DONE indicating that the driver
needs the keys at that point and not earlier.

60b94c9819 Add preliminary background scan and roaming module design
This allows background scanning and roaming decisions to be contained in
a single place based on a defined set of notification events which will
hopefully make it easier to experiment with roaming improvements. In
addition, this allows multiple intra-ESS roaming policies to be used
(each network configuration block can configure its own bgscan module).

The beacon loss and signal strength notifications are implemented for
the bgscan API, but the actual events are not yet available from the
driver.

The included sample bgscan module ("simple") is an example of what can
be done with the new bgscan mechanism. It requests periodic background
scans when the device remains associated with an ESS and has couple of
notes on what a more advanced bgscan module could do to optimize
background scanning and roaming. The periodic scans will cause the scan
result handler to pick a better AP if one becomes available. This bgscan
module can be taken into use by adding bgscan="simple" (or
bgscan="simple:<bgscan interval in seconds>") into the network
configuration block.

3180d7a208 Getting back to DISCONNECTED afer SCANNING
After transitioning from DISCONNECTED to SCANNING, we never go back
to DISCONNECTED even though scanning is done or failed.
We're thus stuck in SCANNING while scanning is actually done.

86b89452f6 Use shared functions for network operations and param changes
Instead of implementing these separately in various control
interface handlers, use shared functions. These add some of the
previously missing notification calls, too, for the affected areas.

8bac466b00 Add wpa_supplicant notification calls
This introduces a new mechanism for collecting notification calls into
a single place (notify.c). As a result of this, most of the
wpa_supplicant code does not need to know about dbus (etc. mechanisms
that could use the notifications). Some empty placeholder functions are
also added in preparation of new dbus code that needs more event
notifications.
