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.
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).
Whenever running wpa_supplicant in AP mode with WPS enabled, the
notifications of missing WPS PIN are now shown on the peer dialog
to make it easier to provide the PIN.
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.
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.
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.
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.
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.
Convert wpa_supplicant_get_scan_results_old() to use the same return
style with the other get_scan_results options and clean up the code
by sharing the same scan result freeing and error checking code for
all the options.
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.
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.
In addition, add a peer entry type for each peer entry. Currently,
this is only stored as an integer and visible in the context menu.
Eventually, different icons should be used based on this type.
This provides some initial functionality for showing peer information,
i.e., showing information about other devices that has been discovered.
Currently, information is only available in the AP mode (list of
associated stations), but this is expected to increase in the future
(e.g., show the current AP in station mode, other stations in IBSS,
etc.). Furthermore, there will be actions available for doing things
like providing a WPS PIN for a station.
wpa_supplicant can now reconfigure the AP by acting as an External
Registrar with the wps_reg command. Previously, this was only used
to fetch the current AP settings, but now the wps_reg command has
optional arguments which can be used to provide the new AP
configuration. When the new parameters are set, the WPS protocol run
is allowed to continue through M8 to reconfigure the AP instead of
stopping at M7.
If an EAPOL frame is received while wpa_supplicant thinks the driver is
not associated, queue the frame for processing at the moment when the
association event is received. This is a workaround to a race condition
in receiving data frames and management events from the kernel.
The pending EAPOL frame will not be processed unless an association
event is received within 100 msec for the same BSSID.
wpa_supplicant can now be built with FIPS capable OpenSSL for FIPS mode
operation. Currently, this is only enabling the FIPS mode in OpenSSL
without providing any higher level enforcement in wpa_supplicant.
Consequently, invalid configuration will fail during the authentication
run. Proper configuration (e.g., WPA2-Enterprise with EAP-TLS) allows
the connection to be completed.
An SMC router was reported to use 0x22 (WPAPSK + WPA2PSK) in the
authentication type of the provisioned credential and wpa_supplicant
rejected this as invalid. Work around this by replacing WPAPSK + WPA2PSK
with WPA2PSK.
This is a (hopefully) temporary workaround to allow the same source code
tree to be used for building hostapd and wpa_supplicant without having
to manually force recompilation of some files. Currently, some of the
driver wrapper files need to be built separately for hostapd and
wpa_supplicant (#ifdef's in the files based on AP functionality).
This is somewhat racy as far as parallel make execution is concerned,
i.e., it may be necessary to run "make -j#" twice (plain "make" works
fine. Since this is supposed to be a temporary workaround, there is not
much point in trying to fix this with any more complex make processing.
Instead of having all driver stuff collected across wpa_supplicant
and hostapd, create a common snippet that they both include and
that handles the build configuration.
