If there is already a link the requested peer, request start of
renegotiation instead of completely new link. This seems to be needed
to allow some driver to accept the trigger for a new negotiation.
tdls_testing 0x80 can now be used to request wpa_supplicant to send
a TDLS Setup Request frame (i.e., try to initiate TDLS setup)
whenever a TDLS Setup Request frame has been received from a peer.
Blindly clearing all struct wpa_tdls_peer members is a risky
operation since it could easily clear pointers to allocated
memory, etc. information that really should not be removed.
Instead of hoping that new code gets added here to restore
the important variables, reverse the approach and only clear
structure members one by one when needed.
This allows the same code path to be used for both protected and
unprotected configurations to limit need for duplicated code in
both the driver and wpa_supplicant.
This adds code for validating that the same Key Lifetime is used
throughout TPK handshake and enables TPK lifetime expiration and
renewal/teardown. These part seem to be working, but the actual
handling of TDLS Setup Confirm and renewal are not fully
functional yet.
tdls_testing bits:
bit 3 = use short TPK lifetime (301 seconds)
bit 4 = use wrong TPK lifetime in TDLS Setup Response
bit 5 = use wrong TPK lifetime in TDLS Setup Confirm
These special test cases can be configured at run time with "wpa_cli
tdls_testing <value>" where <value> is an integer (either as a decimal
or as a hex value with 0x prefix) bitmap of special features with
following bits available at this point:
bit 0 = long frame (add dummy subelement to make FTIE very long)
bit 1 = use alternative RSN IE (different RSN capab value and no extra
replay counters)
bit 2 = send incorrect BSSID in Link Identifier of TDLS Setup Request
(e.g., 1 = long FTIE, 2 = different RSN IE, 3 = both of those)
This is disabled by default and can be enabled for the build by
adding the following line to .config:
CFLAGS += -DCONFIG_TDLS_TESTING
This allows driver wrappers to indicate whether the association was
done using Association Request/Response or with Reassociation
Request/Response frames.
CFLAGS += -DCONFIG_VALGRIND can now be used to enable support for
Valgrind client requests to help in removing some non-issues from
Valgrind reports. This is mainly aimed at allowing unknown ioctl
results to be marked as defined data.
If the os_time_t variable used for the expiration time (seconds)
overflows when the registered timeout value is being added,
assume that the event would happen after an infinite time, i.e.,
would not really happen in practice. This fixes issues with
long key timeouts getting converted to immediate expiration due
to the overflow.
os_snprintf() can be a preprocessor macro and according to
C99 (6.10.3 clause 11) the results of having preprocessor directives
inside the macro arguments is undefined.
Build options can now be used to replace the location of client
sockets for UNIX domain socket control interface:
CFLAGS += -DCONFIG_CTRL_IFACE_CLIENT_DIR=\"/tmp\"
CFLAGS += -DCONFIG_CTRL_IFACE_CLIENT_PREFIX=\"wpa_ctrl_\"
The buffer size for routing socket is fixed to 2048.
This patch fix it to obtain the size from OS.
This patch worked on x86 platform with NetBSD 5.0.2.
This allows keystore:// prefix to be used with client_cert and
private_key configuration parameters.

This will only retrieve information about peers that have been fully
discovered, not peers that are only half-discovered based on their Probe
Request frames.

The DBus code will want to have perfect matching of dev_found and the
dev_lost it adds so it doesn't need to keep track internally. Enable
that with a new flag in the core that tracks whether we have already
notified about this -- the existing users can ignore it.
The part where this is always set to 1 if the new device is discovered
by a driver that has P2P in the driver is buggy -- the driver should
feed the P2P peer database and then that should feed the notification
here instead.

This embeds some information about each P2P peer that will be publically
visible in a struct that is shared.
The dev_found notification function is also passed the new struct, which
requires some work for the driver-based P2P management.

When using multiple vifs and dynamic vlan tagging is enabled on any
interface, the created AP VLAN interfaces get the BSSID of the first
AP mode interface instead of the BSSID of the corresponding AP mode
interface.
Example:
wlan0 - xx:xx:xx:xx:x0
wlan1 - xx:xx:xx:xx:x1
Assume a STA connects to the AP interface wlan1 and gets a dynamic
VLAN tag 100 assigned by the RADIUS server. Hostapd will create an AP
VLAN interface wlan1.100 but doesn't set an address for this interface
which results in wlan1.100 getting the same address as wlan0:
wlan1.100 - xx:xx:xx:xx:x0
As a result the STA that was moved to wlan1.100 isn't able to finish its
4-way handshake since mac80211 won't pass its frames to wlan1.100 due to
the different address.
To fix this issue make use of the address of the AP interface when
creating an AP VLAN interface.

Add MAC addresses for stations and use wpa_msg instead of printf
methods to make it easier to grep logs and find messages for the
station in question.

If parsing of the certificate or private key succeeds using any of
the tried encoding types, clear the OpenSSL error queue without
showing the pending errors in debug log since they do not really
provide any useful output and can be confusing.
This patch fixes a problem I had when I tried to connect
an embedded system [wpa_supplicant, CONFIG_TLS=internal]
to my TLS secured network.
TLSv1: Send CertificateVerify
TLSv1: CertificateVerify hash - hexdump(len=36): ha .. ha
PKCS #1: pkcs1_generate_encryption_block - Invalid buffer lengths \
(modlen=512 outlen=454 inlen=36)
It turned out that a fixed 1000 byte message buffer was just
a little bit too small for the 4096 bit RSA certificates
I'm using.

In multi BSS setups it wasn't possible to set up an HT BSS in
conjunction with a WEP/TKIP BSS. HT needed to be turned off entirely
to allow WEP/TKIP BSSes to be used.
In order to allow HT BSSes to coexist with non-HT WEP/TKIP BSSes add a
new BSS conf attribute "disable_11n" which disables HT capabilities on a
single BSS by suppressing HT IEs in the beacon and probe response
frames. Furthermore, mark all STAs associated to a WEP/TKIP BSS as
non-HT STAs. The disable_11n parameter is used internally; no new entry
is parsed from hostapd.conf.
This allows a non-HT WEP/TKIP BSS to coexist with a HT BSS without
having to disable HT mode entirely. Nevertheless, all STAs associated to
the WEP/TKIP BSS will only be served as if they were non-HT STAs.
