This mode allows associated stations to use 4-address frames to allow
layer 2 bridging to be used. At least for the time being, this is only
supported with driver=nl80211.
Replace driver wrapper calls to hostapd_tx_status(),
hostapd_rx_from_unknown_sta(), hostapd_mgmt_rx(), and
hostapd_mgmt_tx_cb() with new generic driver events
EVENT_TX_STATUS, EVENT_RX_FROM_UNKNOWN, and EVENT_RX_MGMT.
This cleans up lot of the driver wrapper code to be less dependent
on whether it is being used within wpa_supplicant AP mode or hostapd.
This remove the need from driver_test.c to go through internal hostapd
structures to find the appropriate BSS when reporting events on secondary
BSSes.
This removes need for including hostapd/sta_flags.h into driver
wrappers and removes any remaining dependencies between driver flags
and internal hostapd flags.
IEEE 802.11w uses distinct key indexes (4 and 5) so the same
get_seqnum() handler can be used to fetch packet number for both
TKIP/CCMP and BIP(using IGTK).
Since the new get_seqnum_igtk() handler was not actually implemented by
any driver wrapper, this may also fix BIP/IGTK sequence number reporting
with driver_nl80211.c.
There was code for configuring this, but no driver wrapper actually
implements the actual setting. Remove this for now to reduce potential
confusion and to simply the driver interface.
In addition to the bitrate, the only other variable in this structure
is used internally in hostapd. Move this structure into hostapd.h and
make the driver API use simpler data structure (array of bitrates).
These are not really used and can be removed to clean up the driver
interface definition. The only remaining flag (HOSTAPD_RATE_BASIC) can
be removed once the basic rate set indication can be handled
differently.
if_add/if_remove can now be used as the generic driver ops for adding
and removing virtual interfaces of various types. In addition,
driver_nl80211.c is now including this code unconditionally, so that
the functions are not limited only for hostapd.
Print what the kernel believes the current BSS status (authenticated
or associated) is in scan results. In addition, check whether this
matches with the state that wpa_supplicant believes the driver to be
in.
This does not change the actual behavior, but will provide information
that will help in debugging potential issues where cfg80211/mac80211
seems to get into a different state from wpa_supplicant. In addition,
this provides an easy location for a workaround that could be added to
clear cfg80211/mac80211 state for unknown BSSes.
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.
In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.
Instead of using hardcoded maximum A-MPDU length of 64 kB and no
restrictions on minimum MPDU Start Spacing, use the correct values
reported by the driver.
This gets rid of previously deprecated driver_ops handlers set_wpa,
set_drop_unencrypted, set_auth_alg, set_mode. The same functionality
can be achieved by using the init/deinit/associate handlers.
Clean up driver interface by merging hostapd and wpa_supplicant
specific set_beacon driver_ops into a single one. In addition,
merge set_beacon_int into to the same operation.
Current wpa_supplicant has a bug with WEP keys, it adds a zero-length
sequence counter field to netlink which the kernel doesn't accept.
Additionally, the kernel API slightly changed to accept keys only when
connected, so we need to send it the keys after that. For that to work
with shared key authentication, we also include the default WEP TX key
in the authentication command.
To upload the keys properly _after_ associating, add a new flag
WPA_DRIVER_FLAGS_SET_KEYS_AFTER_ASSOC_DONE indicating that the driver
needs the keys at that point and not earlier.
The driver wrappers should not need to include wps_hostapd.h, so let's
make this easier by introducing a driver callback for reporting Probe
Request frames.
None of the driver wrappers user this. hostapd-controlled broadcast SSID
hiding can only be used with drivers that use hostapd for handling
Beacon and Probe Request/Response frames.
None of the driver wrappers use this. Only the drivers that use hostapd
for Beacon and Probe Request/Response handling can now use IEEE 802.11d
properly.
This was not really supported by any of the included driver wrappers. If
this functionality is desired in the future, this (or something similar)
can be added with the changes needed into a driver wrapper to use the
mechanism.
This simplifies driver wrapper operations and removes last direct
struct hostapd_data dereferences from driver_nl80211.c. In addition,
some of the TX callbacks are now fixed for secondary BSSes.
This fixes deauth/disassoc frames in secondary BSSes when using
multi-BSSID. In addition, it reduces need to dereference
struct hostapd_data inside driver wrappers.
Instead of adding a new driver_ops for fetching neighbor BSS data (that
nl80211 driver interface had to scan during initialization), share the
same scan operations that wpa_supplicant is using. This gets rid of
duplicated scan code in driver_nl80211.c (and better yet, removes large
part of old WEXT code).
hostapd interface initialization is now completed in a callback, if
needed, i.e., he_features channel/hw_mode selection can use as much time
as needed. This can also help with radar detection in the future.
Use a parameter structure to pass in information that can be more easily
extended in the future. Include some of the parameters that were
previously read directly from hapd->conf in order to reduce need for
including hostapd/config.h into driver wrappers.
