Initialize struct hostapd_data driver context with the same driver
information that was initialized earlier during wpa_supplicant start.
This allows the AP mode operations to be completed directly with the
same calls in AP code without having to maintain a separate translation
layer between the AP and station mode driver context.
Skip WPS IE building for Beacon and Probe Response frames is set_ie_cb()
is not set. This fixes a memory leak and optimizes operations by not
allocating memory and building the WPS IEs unnecessarily.
This code can be shared by both hostapd and wpa_supplicant and this
is an initial step in getting the generic code moved to be under the
src directories. Couple of generic files still remain under the
hostapd directory due to direct dependencies to files there. Once the
dependencies have been removed, they will also be moved to the src/ap
directory to allow wpa_supplicant to be built without requiring anything
from the hostapd directory.
set_ap_wps_ie() is not used to set WPS IE for both Beacon and Probe
Response frames with a single call. In addition, struct wpabuf is used
instead of separate u8* and length fields. This avoids duplicated
allocation of the IEs and simplifies code in general.
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.
This WPA_TRACE=y additions allows components to register active references
to memory that has been provided to them as a pointer. If such an actively
referenced memory area is freed, tracer will report this as an error and
backtraces of both the invalid free and the location where this pointer
was marked referenced are shown.
This adds config_methods configuration option for wpa_supplicant
following the design used in hostapd. In addition, the string is
now parsed in common code from src/wps/wps_common.c and the list
of configurable methods include all the defined methods from
WPS 1.0h spec.
Since an Enrollee that does not advertise display as one of the
Config Methods is unlikely to be able to show the ASCII passphrase
to the user, prefer PSK format with such an Enrollee to reduce key
derivation time. This can help with some low-powered devices that
would take long time to derive the PSK from the passphrase.
The use_psk_key parameter can now be used to force the Registrar to
use PSK format instead of ASCII passphrase when building a Credential
for the Enrollee. For now, this is not enabled, but it could be enabled
either based on external (to WPS) configuration or automatically set
based on some WPS attribute values from the Enrollee.
Undocumented (at least for the time being) TLS parameters can now
be provided in wpa_supplicant configuration to enable some workarounds
for being able to connect insecurely to some networks. phase1 and
phase2 network parameters can use following options:
tls_allow_md5=1
- allow MD5 signature to be used (disabled by default with GnuTLS)
tls_disable_time_checks=1
- ignore certificate expiration time
For now, only the GnuTLS TLS wrapper implements support for these.
The new TLS wrapper use may end up returning alert data and we need to
make sure here that it does not end up getting interpreted as success
due to non-NULL response.
This converts tls_connection_handshake(),
tls_connection_server_handshake(), tls_connection_encrypt(), and
tls_connection_decrypt() to use struct wpa_buf to allow higher layer
code to be cleaned up with consistent struct wpabuf use.
Use an extra header to move the returned pointer to break os_free()
or free() of the returned value and verify that the correct magic
is present when freeing or resizing the wpabuf. Show backtrace on
invalid wpabuf use.
If Finished message from peer has been received before the server
Finished message, start Phase 2 with the same message to avoid extra
roundtrip when the peer does not have anything to send after the server
Finished message.
Instead of forcefully deinitializing ER immediately, give it some
time to complete unsubscription and call eloop_terminate() only once
ER code has completed its work.
WPA_TRACE=y builds will now verify that memory allocation in done
consistently using os_{zalloc,malloc,realloc,strdup,free} (i.e., no
mixing of os_* functions and unwrapper functions). In addition, some
common memory allocation issues (double-free, memory leaks, etc.) are
detected automatically.
WPA_TRACE=y can now be used to enable internal backtrace support that
will provide more details about implementation errors, e.g., when some
resources are not released correctly. In addition, this will print out
a backtrace automatically if SIGSEGV is received.
As an initial step in sharing netlink helper functions among driver
wrappers, create a new file for netlink code and move operstate send
function there.
This message from tls_connection_handshake() is not really an error in
most cases, so do not show it if there was indeed no Application Data
available (which is a normal scenario and not an indication of any
error).
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.
