Changed accounting_sta_start() to call accounting_sta_get_id()
internally in accounting.c so that external callers do not need to do
anything to allocate unique accounting id. When starting a new session,
a unique identifier is needed anyway, so no need to keep these
operations separate.
This was used to allow hostapd to associate as a non-AP STA to another
AP one the same channel while still acting as an AP with the Host AP
driver. This was very experimental and did not work with all firmware
versions. Nowadays, much better way of doing this is to use mac80211
virtual non-AP STA interface. As such, this experimental code can be
removed from hostapd to reduce the code size and make MLME code easier
to understand since it is now only handling AP functionality.
This code was originally added as a mechanism to handle long waits
during channel selection and/or radar detection. It is not currently
really used and makes the setup sequence nearly impossible to
understand. Let's get rid of the unwanted complexity. This needs to be
redesigned if it is ever needed again.
This code was not finished and did not work with the current mac80211
design. In order to avoid confusing users, it is better to remove this
completely for now and look at new implementation to work with mac80211.
It the message was large enough to require fragmentation (e.g., if a large
Session Ticket data is included), More Fragment flag was set, but no
more fragments were actually sent (i.e., Access-Accept was sent out).
These typedefs were causing build issues with new kernel/C library headers,
so lets get rid of them since they do not seem to be needed anymore. This
applies only if CONFIG_FULL_DYNAMIC_VLAN is enabled which is not even
mentioned in the defconfig file, so this should not change behavior more
most users.
If the driver wrapper does not implement passive_scan handler, do not try
to use strerror() to figure out what the error meant. This is not really an
error that the user should be notified about.
(e.g., via driver_nl80211 when using mac80211) instead of using hostapd as
the source of the regulatory information (i.e., information from CRDA is
now used with mac80211); this allows 5 GHz channels to be used with hostapd
(if allowed in the current regulatory domain).
Updated OpenSSL code for EAP-FAST to use an updated version of the
session ticket overriding API that was included into the upstream
OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
needed with that version anymore).
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.
We need to cancel the group key update for a STA if a reauthentication
request is received while the STA is in pending group key update. When
canceling the update, we will also need to make sure that the PTK Group Key
state machine ends up in the correct state (IDLE) to allow future updates
in case of WPA2.
Changed EAP-FAST configuration to use separate fields for A-ID and
A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
16-octet len binary value for better interoperability with some peer
implementations; eap_fast_a_id is now configured as a hex string.
Previous version could have allowed a broken client to complete WPA (or
WPA2) authentication even if the selected proto was not enabled in hostapd
configuration.
eap_fast_prov config parameter can now be used to enable/disable different
EAP-FAST provisioning modes:
0 = provisioning disabled
1 = only anonymous provisioning allowed
2 = only authenticated provisioning allowed
3 = both provisioning modes allowed
A recent kernel change led to all EAPOL frames being encrypted rather than
just those for the group handshake. This is due to transmit processing in
the kernel now using the proper interface which would encrypt those frames
with the group key because hostapd wasn't requesting that they not be
encrypted. This changes the nl80211 driver to not request encryption unless
the EAPOL frame should be encrypted.

IEEE 802.11w/D6.0 defines new AKMPs to indicate SHA256-based algorithms for
key derivation (and AES-CMAC for EAPOL-Key MIC). Add support for using new
AKMPs and clean up AKMP processing with helper functions in defs.h.
Move the use of 802.11 header protocol field into driver_hostap.c since
this is a Host AP driver specific mechanism and other driver wrappers
should not really need to know about it.
This updates management frame protection to use the assocition ping process
from the latest draft (D6.0) to protect against unauthenticated
authenticate or (re)associate frames dropping association.
This adds most of the new frame format and identifier definitions from IEEE
802.11w/D6.0. In addition, the RSN IE capability field values for MFP is
replaced with the new two-bit version with MFPC (capable) and MFPR
(required) processing.
This allows the accept_mac_file to be used as an alternative for RADIUS
server-based configuration. This is mainly to ease VLAN testing (i.e., no
need to set up RADIUS server for this anymore).
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
establish the tunnel.
The configuration data should only store the static configuration data and
not dynamic data. In addition, storing HT configuration and state in IEs is
not the easiest way of doing this, so use more convenient data types for
storing configuration and dynamic state. The HT IEs are then generated
based on the static configuration and dynamic state whenever needed.
