No need for a separate driver_ops handler for setting DTIM period since
this is always set at the same time with the Beacon data. Beacon
interval is still set separately since it is consider per-radio
parameter (Beacon data and DTIM period are per-BSS parameters).
IEEE 802.11r KDF uses key length in the derivation and as such, the PTK
length must be specified correctly. The previous version was deriving
using 512-bit PTK regardless of the negotiated cipher suite; this works
for TKIP, but not for CCMP. Update the code to use proper PTK length
based on the pairwise cipher.
This fixed PTK derivation for both IEEE 802.11r and IEEE 802.11w (when
using AKMP that specifies SHA-256-based key derivation). The fixed
version does not interoperate with the previous versions. [Bug 307]
mac80211 does not use this type of Michael MIC event, so this is not
really used and proper Michael MIC failure processing will be added
using an nl80211 event once that gets added into wireless-testing.git.
It looks like both new nl80211 operations (scan and auth/assoc) end up
being added in Linux 2.6.30, so we do not need to maintain the backwards
compatibility code in wpa_supplicant.
Update credential to only include a single authentication and
encryption type in case the AP configuration includes more than one
option. Without this, the credential would be rejected if the AP was
configured to allow more than one authentication type.
A new network block parameter, scan_freq, can be used to specify subset
of frequencies to scan. This can speed up scanning process considerably
if it is known that only a small subset of channels is actually used in
the network. A union of configured frequencies for all enabled network
blocks is used in scan requests.
Currently, only driver_nl80211.c has support for this functionality.
For example, following parameter marks 2.4 GHz channels 1, 6, 11 to be
scanned: scan_freq=2412 2437 2462
wpa_supplicant can now initialize hostapd data structures when mode=2 is
used to set up an AP. The hostapd configuration is not yet set based on
wpa_supplicant network configuration block. In addition, the glue code
for hostapd driver_ops needs number of functions that will be needed for
AP functionality.
Move the shared IEEE 802.11w enum definition into src/common/defs.h to
avoid redefinition when both configuration structures are included into
the same file.
The memcpy was using incorrect size (of pointer; should have been of
data structure) for the client address. This ended up working on 64-bit
targets, but left part of the address uninitialized on 32-bit targets.
The actual pointer to struct sta_info was not really used and it is
enough to use a single bit to indicate whether an AID is allocated. This
makes the BSS data take less memory while making the allocation routine
faster and removing the arbitrary MAX_AID_TABLE_SIZE limit of 128 STAs.
This version is adding the configuration option (mode=2) for this and
driver capability reporting to figure out whether AP mode can be used.
However, this does not actually implement any real functionality yet.
Need to set drv->ifindex before calling set_mode(). In addition, set the
mode before setting the interface up to avoid having to set it down
again.
Add more useful error message on mode changes.
All these driver handlers can be implemented in associate() handler
which gets all the needed information in the parameters structure. The
old functions that provided only a single parameter will be removed
eventually to clean up the driver_ops structure, so driver wrappers
should start using the newer mechanism.
Remove all fields before sun_path before printing or comparing sun_path
contents. Using offsetof should be portable. In addition, set sun_len
for FreeBSD.
Removing just sun_family is not portable since some systems (e.g.,
FreeBSD) include an additional sun_len field. Using offsetof should be
portable. In addition, set sun_ken for FreeBSD.
