This merges the driver wrapper implementations to use the same
implementation both for hostapd and wpa_supplicant operations to avoid
code duplication.
This commit merges the driver_ops structures and implementations from
hostapd/driver*.[ch] into src/drivers. This is only an initial step and
there is room for number of cleanups to share code between the hostapd
and wpa_supplicant parts of the wrappers to avoid unnecessary source
code duplication.
Need to set WEP keys before requesting authentication in order to get
Shared Key authentication working. Previously, the WEP keys were not set
at all when using SME in wpa_supplicant.
This fixes multi-BSS configuration with driver_nl80211.c to mark STAs
that use secondary BSSes with open/static WEP without having to make
driver_nl80211.c track 802.1X configuration for each BSS.
Static WEP keys were configured only for the first BSS. In addition,
STAs were flushed only for the first BSS. These operations should be in
hostapd_setup_bss(), not setup_interface().
Remove extra call to ieee802_11_set_beacon() for the first BSS. This
should only be done from hostapd_setup_bss(), i.e., once for each BSS.
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.
