116654ce24 WPS: Moved wps_context initialization into wps_supplicant.c
The wps_context data is now managed at wpa_supplicant, not EAP-WSC. This
makes wpa_supplicant design for WPS match with hostapd one and also
makes it easier configure whatever parameters and callbacks are needed
for WPS.

bcbbc7af45 WPS: Merged two cred_cb variables into the same one
Previously, wpa_supplicant as Enrollee case was handled using a
different callback function pointer. However, now that the wps_context
structure is allocated for all cases, the same variable can be used in
all cases.

ff434cbdda WPS: Moved device attributes into wps_context::dev for Enrollee case
Previously, hardcoded values were used in wps_enrollee.c. These are now
moved into shared data in struct wps_context. In case of
AP/Authenticator, these are initialized in wps_hostapd.c. In case of
client/supplicant, these are now initialized in EAP-WSC peer method,
but will probably end up being moved into higher layer for better
configuration.

9d695f3dd0 WPS: Update supplicant configuration when acting as an external Registrar
This allows the network to be used after the Registrar configuration
step. The local WPS network is replaced with a new network block
similarly to the case of acting as an Enrollee.

3f42d42c07 WPS: Moved Credential building to use struct wps_credential
This makes it easier to store old AP settings into wps->cred (and allow
them to modified and taken into use in the future). Separation between
Credential and AP Settings building is also cleaner in this design.

96a2ed9f50 WPS: Process old AP Settings in M7 when registering as external Registrar
The old (i.e., currently used) AP Settings are processed. For now, they
are copied as-is into M8 as new AP Settings to avoid changing
configuration. This should be changed to allow external programs (e.g.,
GUI) to fetch the old AP settings over ctrl_iface and then allow
settings to be changed before sending M8 with the new settings.

fced73755f WPS: Moved Credential and AP Settings processing in common code
The core processing of attributes into struct wps_credential is now in
wps_common.c (was in wps_enrollee.c), so that the same code can be
shared with Registrar.

ad08c3633c Added preliminary Wi-Fi Protected Setup (WPS) implementation
This adds WPS support for both hostapd and wpa_supplicant. Both programs
can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN
methods are supported.

Currently, hostapd has more complete configuration option for WPS
parameters and wpa_supplicant configuration style will likely change in
the future. External Registrars are not yet supported in hostapd or
wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.

1ac2d4a9ee Fixed canceling of PMKSA caching with driver generated RSN IE
It looks like some Windows NDIS drivers (e.g., Intel) do not clear the
PMKID list even when wpa_supplicant explicitly sets the list to be
empty. In such a case, the driver ends up trying to use PMKSA caching
with the AP and wpa_supplicant may not have the PMK that would be needed
to complete 4-way handshake.

RSN processing already had some code for aborting PMKSA caching by
sending EAPOL-Start. However, this was not triggered in this particular
case where the driver generates the RSN IE. With this change, this case
is included, too, and the failed PMKSA caching attempt is cleanly
canceled and wpa_supplicant can fall back to full EAP authentication.

98842d51ec Separate OpenSSL engine configuration for Phase 2
I fixed the engine issue in phase2 of EAP-TTLS. The problem was that you
only defined one engine variable, which was read already in phase1. I
defined some new variables:

engine2
engine2_id
pin2

and added support to read those in phase2 wheres all the engine
variables without number are only read in phase1. That solved it and I
am now able to use an engine also in EAP-TTLS phase2.

e519314ee9 Add RoboSwitch driver interface for wpa_supplicant
Find attached the patch that creates a new driver: roboswitch. This
driver adds support for wired authentication with a Broadcom
RoboSwitch chipset. For example it is now possible to do wired
authentication with a Linksys WRT54G router running OpenWRT.

LIMITATIONS
- At the moment the driver does not support the BCM5365 series (though
adding it requires just some register tweaks).
- The driver is also limited to Linux (this is a far more technical
restriction).
- In order to compile against a 2.4 series you need to edit
include/linux/mii.h and change all references to "u16" in "__u16". I
have submitted a patch upstream that will fix this in a future version
of the 2.4 kernel. [These modifications (and more) are now included in
the kernel source and can be found in versions 2.4.37-rc2 and up.]

USAGE
- Usage is similar to the wired driver. Choose the interfacename of
the vlan that contains your desired authentication port on the router.
This name must be formatted as <interface>.<vlan>, which is the
default on all systems I know.

ea251b4a23 EAP-FAST: Reorder TLVs in PAC Acknowledgment to fix interop issues
It looks like ACS did not like PAC Acknowledgment TLV before Result TLV, so
reorder the TLVs to match the order shown in a
draft-cam-winget-eap-fast-provisioning-09.txt example. This allows
authenticated provisioning to be terminated with Access-Accept (if ACS has
that option enabled). Previously, provisioning was otherwise successful,
but the server rejected connection due to not understanding the PAC Ack
("Invalid TEAP Data recieved").

36100718de EAP-FAST server: allow expired PAC for PAC refresh
Instead of falling back to full TLS handshake on expired PAC, allow the
PAC to be used to allow a PAC update with some level of server
authentication (i.e., do not fall back to full TLS handshake since we
cannot be sure that the peer would be able to validate server certificate
now). However, reject the authentication since the PAC was not valid
anymore. Peer can connect again with the newly provisioned PAC after this.

581a8cde77 Added support for enforcing frequent PTK rekeying
Added a new configuration option, wpa_ptk_rekey, that can be used to
enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP
deficiencies. This can be set either by the Authenticator (to initiate
periodic 4-way handshake to rekey PTK) or by the Supplicant (to request
Authenticator to rekey PTK).

With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP
keys will not be used for more than 10 minutes which may make some attacks
against TKIP more difficult to implement.

the other order, so change the order here, too, to make it less likely to
hit this type of interop issues.

ec5f180a24 Add an optional set_mode() driver_ops handler for setting mode before keys
A bug just got reported as a result of this for mac80211 drivers.

https://bugzilla.redhat.com/show_bug.cgi?id=459399

The basic problem is that since taking the device down clears the keys
from the driver on many mac80211-based cards, and since the mode gets
set _after_ the keys have been set in the driver, the keys get cleared
on a mode switch and the resulting association is wrong.  The report is
about ad-hoc mode specifically, but this could happen when switching
from adhoc back to managed mode.

fd630bc183 Fixed WEXT scan result parser to not crash on invalid IEs (zero len buffer)
If IWEVGENIE or custom event wpa_ie/rsn_ie is received in scan with empty
buffer, the previous version ended up calling realloc(NULL, 0) which seems
to return a non-NULL value in some cases. When this return value is passed
again into realloc with realloc(ptr, 0), the returned value could be NULL.
If the ptr is then freed (os_free(data.ie) in SIOCGIWAP handling), glibc
may crash due to invalid pointer being freed (or double-freed?). The
non-NULL realloc(NULL, 0) return value from glibc looks a bit odd behavior,
but anyway, better avoid this case completely and just skip the IE events
that have an empty buffer.

This issue should not show up with drivers that produce proper scan results
since the IEs will always include the two-octet header. However, it seems
to be possible to see this when using 64-bit kernel and 32-bit userspace
with incorrect compat-ioctl processing.

4d4233eaf4 Fixed internal TLSv1 server implementation for abbreviated handshake
When the TLS handshake had been completed earlier by the server in case of
abbreviated handshake, the output buffer length was left uninitialized. It
must be initialized to zero in this case. This code is used by EAP-FAST
server and the uninitialized length could have caused it to try to send a
very large frame (though, this would be terminated by the 50 roundtrip EAP
limit). This broke EAP-FAST server code in some cases when PAC was used to

de9289c8e9 Add preliminary IEEE 802.11n support into hostapd
This commit brings in cleaned up version of IEEE 802.11n implementation
from Intel (1). The Intel tarball includes number of other changes, too,
and only the changes specific to IEEE 802.11n are brought in here. In
addition, this does not include all the changes (e.g., some of the
configuration parameters are still missing and driver wrapper changes for
mac80211 were not included).

couple of pending patches to be integrated in order to get userspace client
MLME working again).

1c8735848d nl80211: Preliminary code for usermode MLME support
This adds some parts needed to use usermode MLME with the current mac80211
(plus a patch to add a new cfg80211 command; not yet submitted to
wireless-testing). This version creates a monitor interface for management
frames and is able to send Probe Request frames during scan. However, it
looks like management frame reception is not yet working properly. In
addition, mlme_{add,remove}_sta() handlers are still missing.

7524cfb1a3 nl80211: Fixed re-initialization of removed and re-inserted interface
Network device ifindex will change when the interface is re-inserted.
driver_nl80211.c will need to accept netlink events from "unknown" (based
on ifindex) interfaces when a previously used card was removed earlier. If
the previously removed interface is added back, the driver_wext data need
to be updated to match with the new ifindex value. In addition, the initial
setup tasks for the card (set interface up, update ifindex, set mode, etc.)
from wpa_driver_nl80211_init() need to be run again.

This is the changes from commit 3fbda8f943

3ff77e070d Fixed opportunistic key caching (OKC)
wpa_sm_set_config() can be called even if the network block does not
change. However, the previous version ended up calling
pmksa_cache_notify_reconfig() every time and this cleared the network
context from PMKSA cache entries. This prevented OKC from ever being used.

Do not call pmksa_cache_notify_reconfig() if the network context remains
unchanged to allow OKC to be used.

93ef879f0f wext: fix maxrate calculation
When scan results got moved from wpa_scan_result -> wpa_scan_res, the
'maxrate' member was dropped from wpa_scan_res.  The D-Bus interface
used 'maxrate', which was replaced with wpa_scan_get_max_rate().
Unfortunately, wpa_scan_get_max_rate() returns 802.11 rate values
directly from the IE, where 'maxrate' was the rate in bits/second.  The
supplicant internally fakes an IE for wpa_scan_res from the value of
wpa_scan_result->maxrate, but interprets ->maxrate as an 802.11 rate
index.

As a side-effect, this fixes a soft-break of the D-Bus control API since
the wpa_scan_res change was introduced.

886a807fb5 Make proactive key caching working again
Function 'wpa_sm_set_config' used the argument 'config' as the network
context which is a pointer to a local variable of the function
'wpa_supplicant_rsn_supp_set_config'.

This is one reason why no proactive key was generated. This network
context never matched with the network context saved in the pmksa cache
entries.

The structure 'rsn_supp_config' has already a member 'network_ctx' which
is now filled in by this patch with 'ssid'.

3e2ad1b932 Fixed race condition between disassociation event and group key handshake
This avoids getting stuck in state where wpa_supplicant has canceled scans,
but the driver is actually in disassociated state. The previously used code
that controlled scan timeout from WPA module is not really needed anymore
(and has not been needed for past four years since authentication timeout
was separated from scan request timeout), so this can simply be removed to
resolved the race condition. As an extra bonus, this simplifies the
interface to WPA module.

separately, the simplest fix is to just combine these into a single 4-octet

7e1488494e Do not continually reschedule specific scans to help finding hidden SSIDs
In situations where the driver does background scanning and sends a
steady stream of scan results, wpa_supplicant would continually
reschedule the scan.  This resulted in specific SSID scans never
happening for a hidden AP, and the supplicant never connecting to the AP
because it never got found.  Instead, if there's an already scheduled
scan, and a request comes in to reschedule it, and there are enabled
scan_ssid=1 network blocks, let the scan happen anyway so the hidden
SSID has a chance to be found.

mac80211 sends _both_ channel and frequency in it's scan results, with
frequency first and channel second (it's since been fixed to send
channel first and frequency second to work around this issue).  This
results in wpa_supplicant getting the right value when the frequency
comes, but overwriting the value with '0' when the channel comes because
wpa_supplicant can't handle 5GHz channel numbers.  So if a valid
previous SIOCGIWFREQ event came in, don't try to overwrite it.

bf206cada3 Changed TLS server to use OpenSSL SSL_accept() instead of SSL_read()
The server handshake processing was still using SSL_read() to get OpenSSL
to perform the handshake. While this works for most cases, it caused some
issues for re-authentication. This is now changed to use SSL_accept() which
is more approriate here since we know that the handshake is still going on
and there will not be any tunneled data available. This resolves some of
the re-authentication issues and makes it possible for the server to notice
if TLS processing fails (SSL_read() did not return an error in many of
these cases while SSL_accept() does).

Set session id context to a unique value in order to avoid fatal errors
when client tries session resumption (SSL_set_session_id_context() must be
called for that to work), but disable session resumption with the unique
value for the time being since not all server side code is ready for it yet
(e.g., EAP-TTLS needs special Phase 2 processing when using abbreviated
handshake).

Changed EAP-TLS server not to call TLS library when processing the final
ACK (empty data) from the client in order to avoid starting a new TLS
handshake with SSL_accept().

ef626b4d50 Added a workaround for handling TLS compression
Even though we try to disable TLS compression, it is possible that this
cannot be done with all TLS libraries. For example, OpenSSL 0.9.8 does not
seem to have a configuration item for disabling all compression (0.9.9 has
such an option). If compression is used, Phase 2 decryption may end up
producing more data than the input buffer due to compressed data. This
shows up especially with EAP-TNC that uses very compressible data format.

As a workaround, increase the decryption buffer length to (orig_len+500)*3.
This is a hack, but at least it handles most cases. TLS compression should
really be disabled for EAP use of TLS, but since this can show up with
common setups, it is better to handle this case.

EAP-PEAP was the only method that used the external eap_tlv.c peer
implementation. This worked fine just for the simple protected result
notification, but extending the TLV support for cryptobinding etc. is not
trivial with such separation. With the TLV processing integrated into
eap_peap.c, all the needed information is now available for using
additional TLVs.

a865bd5031 Some cleanup for the new driver wrapper for PS3
wpa_printf() does not use '\n'. Fixed set_wpa_key() to allocate buf for
ASCII passphrase case.

b5a357b476 Add support for PS3 Linux wireless driver
This adds support for PS3 wireless to wpa_supplicant.

Although PS3 wireless driver is designed to conform the WEXT standard
as much as possible, unfortunately the wext driver wrapper of
wpa_supplicant can not support PS3 wireless fully because:

 - PS3 wireless driver uses private WEXT ioctls for accepting PSK of
   WPA-Personal from the userland.
   WEXT does not specify the way to do it.

 - The association and 4-way handshake are done by PS3 virtual
   wireless device. The guest OSes can not interfere it.

 - No EAPOL frames are allowed to go outside of the
   hypervisor/firmware nor come from. They are eaten by the firmware.

Thus I needed to make a new driver wrapper for PS3 wireless.

This patch can be applied against the latest 0.6.x tree.

658d166297 FT: Use correct BSSID when deriving PTK and verifying MIC
The old version was using struct wpa_sm::bssid which is not necessarily
updated to point to the correct target address when doing over-the-air FT
since the address is used before the association has actually been
completed.

58a98fb027 Delete PTK SA on (re)association if this is not part of a Fast BSS
Transition. This fixes a potential issue where an incorrectly behaving AP
could send a group key update using the old (now invalid after reassociate)
PTK. This could also happen if there is a race condition between reporting
received EAPOL frames and association events.

c80a74d70c TNC: Integrated TNC support into EAP-TTLS server

extra roundtrip of MSCHAPv2 success message.

7db0fca522 TNC: Integrated TNC support into EAP-FAST server
Tunneled EAP sequence is now used to perform both the authentication (e.g.,
using EAP-GTC) and TNC validation (EAP-TNC) inside the EAP-FAST tunnel if
TNC has been enabled.

da08a7c732 TNC: Added preliminary TNC implementation for hostapd
This adds EAP-TNC method and TNCS (IF-IMV and IF-TNCCS) functionality.
There is no integration with EAP-TTLS and EAP-FAST at this point, so this
version is not yet suitable for real use (i.e., EAP-TNC can only be tested
outside a tunnel which is not an allowed configuration for deployment).
However, the basic TNCS functionality is more or less complete and this
version seems to interoperate with wpa_supplicant.

7914585fe0 EAP-FAST: Cleaned up TLV processing and added support for EAP Sequences
Number of TLVs were processed in groups and these cases were now separated
into more flexible processing of one TLV at the time. wpabuf_concat()
function was added to make it easier to concatenate TLVs. EAP Sequences are
now supported in both server and peer code, but the server side is not
enabled by default.
