edd360e170 Do not store dynamic HT IEs in configuration structures
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.

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).

3c83f19c80 Added mlme_{add,remove}_sta() for userspace MLME
These functions are based on the hostapd implementation and complete
the userspace MLME code in wpa_supplicant (though, mac80211 will still need
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
(driver_wext.c) ported for driver_nl80211.c.

358921edb7 Added support for setting BSS parameters with NL80211_CMD_SET_BSS
This new cfg80211 command is used for setting CTS protect, short preamble,
and short slot time parameters for the BSS. The matching kernel change has
been submitted, but is not yet included in wireless-testing. The code here
used #ifdef to avoid compilation failures before the new command is
available.

bf98f7f3bc Added support for opportunistic key caching (OKC)
This allows hostapd to share the PMKSA caches internally when multiple
BSSes or radios are being controlled by the same hostapd process.

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.

6652b61cd4 Fixed EAP-TNC not to include extra EAP header and TNC flags
The change to support fragmentation added extra function to generate the
EAP header, but forgot to remove the original code and ended up getting two
EAP headers and TNC flags field in the generated message. These header
fields need to be added only in the function that builds the final message
(and if necessary, fragments the data).

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'.

9d6762cfca man wpa_supplicant: Clearly state which options are given per interface
Documentation appeared a little vague about which options are global and
which are tied to a particular interface. This leads to confusion when
using certain combinations of options, e.g. the command "wpa_supplicant
-c /etc/wpa_supplican.conf -u" will not do what is intuitively expected
from it - it will not read the config file given with -c option because
no -i option was given. This command is still valid because -u option is
used. The wpa_supplicant running like this will also not listen on any
control socket, because the socket file name is usually given in the
config file. This command line also happens to be the default in Fedora 9.
This patch does not try to change any behaviour, but rather document
these nuances clearly.

eb0699b6ba Add IGTK/MFP configuration (disabled by default)
Added code to use suggested nl80211/cfg80211 API for setting MFP related
parameters. This is disabled by default since the API changes has not yet
been approved. The new commands can be enabled by defining
NL80211_MFP_PENDING (this will be removed once the API changes is
approved).

Added configuration of MFP related parameters with WEXT. The changes to

code using them is still open to changes and is ifdef'ed out if
CONFIG_IEEE80211W is not set.

de08c7248d Added mac80211_hwsim - software simulator of 802.11 radio(s) for mac80211
mac80211_hwsim is a Linux kernel module that can be used to simulate
arbitrary number of IEEE 802.11 radios for mac80211 on a single
device. It can be used to test most of the mac80211 functionality and
user space tools (e.g., hostapd and wpa_supplicant) in a way that
matches very closely with the normal case of using real WLAN
hardware. From the mac80211 view point, mac80211_hwsim is yet another
hardware driver, i.e., no changes to mac80211 are needed to use this
testing tool.

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.
