If PBC session overlap is detected during an ongoing PBC protocol run,
reject the run (if M8, i.e., credentials, have not yet been sent). This
provides a bit longer monitoring time at the Registrar for PBC mode to
catch some cases where two Enrollees in PBC mode try to enroll
credentials at about the same time.
This provides information about PBC mode result from the WPS Registrar
module. This could be used, e.g., to provide a user notification on the
AP UI on PBC failures.
If PBC session overlap is detected between button press on the registrar
and M1 is reception, report session overlap with the Config Error
attribute in M2D to the Enrollee.
Force deauthentication from the AP to clear mac80211 state (it would get
stuck with future scans if the AP is left in authenticated, but not
associated, state).
Add blacklist entry for the AP to allow other APs with worse signal
strength to be tried (e.g., when APs are trying to do load balancing
with status code 17). Reduce wait for the next scan to speed up
connection in cases where there could be other APs that could accept
association, but which show worse signal strength.
This functionality fits better with src/tls (i.e., internal TLS
implementation), so move it there to make crypto_internal.c more
of a wrapper like other crypto_*.c files.
Private keys can now be used in either unencrypted or encrypted
PKCS #8 encoding. Only the pbeWithMD5AndDES-CBC algorithm (PKCS #5)
is currently supported.
Recognize the PEM header "BEGIN PRIVATE KEY" as base64-decode the data
to be able to use PEM encoded, unencrypted PKCS#8 private keys with the
internal TLS implementation. Previously, only DER encoding of the
PKCS#8 private key was supported.
OpenSSL 0.9.7 does not include get_rfc3526_prime_1536() function, so
provide that functionality internally if needed. In addition, make
sha256_vector() building depend on whether SHA256 support is included
in the OpenSSL library. This with CONFIG_INTERNAL_SHA256=y in .config
allows OpenSSL without SHA256 support to be used.
Previously, APs that were hiding SSID (zero-length SSID IE in
Beacon frames) could have been selected when wildcard SSID matching
was used. This would result in failed association attempt since
the client does not know the correct SSID. This can slow down WPS
which is often using wildcard SSID matching.
Ignore BSSes without known SSID in the scan results when selecting
which BSS to use.
This patch completely separates supplicant's code from dbus.
It introduces three new notifications which copes with all
remaining dbus stuff.
wpas_notify_unregister_interface() was renamed to
wpas_notify_iface_removed().
The hostapd/wpa_supplicant compilation failed with CONFIG_IEEE80211R=y
or CONFIG_IEEE80211W=y option if CONFIG_EAP_PSK and CONFIG_EAP_GPSK are
not used.
Both hostapd/wpa_supplicant compilation fails on DragonFly BSD.
This patch solves this issue.
I have tested only compilation. Not functionality.
Because I don't have any device which can work on DragonFly BSD.
mac80211 does not currently allow (re)authentication when we are already
authenticated. In order to work around this, force deauthentication if
nl80211 authentication command fails with EALREADY. Unfortunately, the
workaround code in driver_nl80211.c alone is not enough since the
following disconnection event would clear wpa_supplicant authentication
state. To handle this, add some code to restore authentication state
when using userspace SME.
This workaround will hopefully become unnecessary in some point should
mac80211 start accepting new authentication requests even when in
authenticated state.
Reorganize the TLS/crypto library segments into a single set of blocks
for each library instead of multiple locations handling library-specific
operations. Group crypto functionality together and get wpa_supplicant
and hostapd Makefile closer to eachother in order to make it easier to
eventually move this into a shared makefile.
Crypto library wrappers can now override the internal DH (group 5)
implementation. As a starting point, this is done with OpenSSL. The
new mechanism is currently available only for WPS (i.e., IKEv2 still
depends on the internal DH implementation).
Replace "nl80211: Ignored unknown event (cmd=33)" with
"nl80211: Scan trigger" to make debug output clearer. We do not
currently do anything with this event apart from showing it in
the debug log.
When checking the validity of VLAN ID based on RADIUS-based ACL or
accept_mac_file, the assigned vlan_id, not the old sta->vlan_id
(likely zero) needs to be used.
This allows NSS to be used to derive EAP-TLS/PEAP/TTLS keying material.
NSS requires a patch from
https://bugzilla.mozilla.org/show_bug.cgi?id=507359
to provide the new API. In addition, that patch needs to be modified to
add the 16-bit context length value in SSL_ExportKeyingMaterial() only if
contextlen != 0 in order to match with the EAP-TLS/PEAP/TTLS use cases.
This issue seems to be coming from the unfortunate incompatibility in
draft-ietf-tls-extractor-07.txt (draft-ietf-tls-extractor-00.txt would
have used compatible PRF construction).
At this point, it is unclear how this will be resolved eventually, but
anyway, this shows a mechanism that can be used to implement EAP key
derivation with NSS with a small patch to NSS.
Whenever running wpa_supplicant in AP mode with WPS enabled, the
notifications of missing WPS PIN are now shown on the peer dialog
to make it easier to provide the PIN.
If no BSSes/IBSSes matching the enabled networks are found in the scan
results, IBSS/AP mode network (if configured) can be created in
ap_scan=1 mode instead of requiring ap_scan=2 mode to be used whenever
using IBSS or AP mode.
