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.
This can be used, e.g., with mac80211-based Linux drivers with
nl80211. This allows over-the-air FT protocol to be used (IEEE
802.11r).
Since the nl80211 interface needed for this is very recent (added
today into wireless-testing.git), driver_nl80211.c has backwards
compatibility code that uses WEXT for association if the kernel does
not support the new commands. This compatibility code can be
disabled by defining NO_WEXT_COMPAT. That code will also be removed
at some point to clean up driver_nl80211.c.
On "eap_tnc_process" function error case, data->in_buf keeps reference
to a local scope variable. For example this will cause segmentation
fault in "eap_tnc_deinit" function "wpabuf_free(data->in_buf)"
statement.
This was broken by 510c02d4a3 which added
validation of eap_ttls_phase2_eap_init() return value. The main problem
in the code trying to initialize a new phase 2 EAP method
unconditionally; this should only happen if there is a new method in the
inner method sequence.
This is based on a patch and report by Masashi Honma
<honma@ictec.co.jp>. The issue is more generic than just TNC, though,
since failure to initialize any phase 2 EAP method can result in NULL
dereference.
On PEAP(TNC), hostapd integrated RADIUS server doesn't return
EAP-Failure when "Recommendation = none". So, EAP data retransmittion
occurs.
My co-worker "Ryuji Ohba" made below patch.
If every secondary BSS is configured with a pre-set BSSID, hostapd does
not enforce the BSSID mask requirements anymore, i.e., they are used
only if hostapd is responsible for generating MAC addresses for virtual
interfaces.
This is needed to make mac80211 work with multi-BSS configuration. The
previous design ended up setting DTIM period for secondary BSSes before
setting the Beacon and driver_nl80211.c was not really prepared for
that. Eventually, the Beacon configuration routines should be combined
into a single driver operation, but for now, just moving this call is
the simplest workaround.
hostapd will now go through the RIC Request and process each RDIE. Only
WMM TSPEC requests are currently supported; all other request
descriptors will be declined.
RIC Response is written by hostapd and verified by wpa_supplicant (MIC
validation). wpa_supplicant does not yet have code to notify the driver
about the resource request results.
