On WPS init/deinit process, the hostapd clears it's own WPS IE
with 0 length WPS IE. But it fails. Because the parameter to
ioctl is too short. Then hostapd prints a below message.
ioctl[IEEE80211_IOCTL_SET_APPIEBUF]: Invalid argument
Allow more than one pending PutWLANMessage data to be stored (M2/M2D
from multiple external Registrars) and drop pending M2/M2D messages when
the Enrollee replies with M3.
It looks like Intel wsccmd may send a bogus NewWLANEventMAC
(11:22:33:44:55:66) when acting as an wired external Registrar. Work
around this by going through all STAs if the address does not match and
pick the STA that is in an ongoing WPS registration.
If you don't choose OpenSSL as TLS implementation and choose to enable
CONFIG_EAP_TNC you have to link against libdl. The OpenSSL libraries
implicitly link against them, so this might be a reason why it wasn't
noticed yet. I assume the same applies to hostapd.
We can now handle up to 65535 byte result buffer which is the maximum
due to WEXT using 16-bit length field. Previously, this was limited to
32768 bytes in practice even through we tried with 65536 and 131072
buffers which we just truncated into 0 in the 16-bit variable.
This more or less doubles the number of BSSes we can received from scan
results.
MadWifi is unlikely to be in ../head relative to hostapd or
wpa_supplicant, as it would be inside the hostap git repository.
MadWifi sources are more likely to be in a directory called "madwifi"
and residing outside the hostap repository. Using "madwifi" also
demonstrates that the top-level madwifi directory is needed.
Try to match PRI/SEC channel with neighboring 20/40 MHz BSSes per
IEEE 802.11n/D7.0 11.14.3.2. This is not yet complete implementation,
but at least some parts of the 40 MHz coex are improved.
40 MHz operation maybe rejected (i.e., fall back to using 20 MHz) or
pri/sec channels may be switched if needed.
I think that the "radius" pointer in the structure hostapd_config is
never used; when the configuration is parsed the related data is stored
in hostapd_bss_config's "radius" var.
This adds mostly feature complete external Registrar support with the
main missing part being proper support for multiple external Registrars
working at the same time and processing of concurrent registrations when
using an external Registrar.
This code is based on Sony/Saice implementation
(https://www.saice-wpsnfc.bz/) and the changes made by Ted Merrill
(Atheros) to make it more suitable for hostapd design and embedded
systems. Some of the UPnP code is based on Intel's libupnp. Copyrights
and licensing are explained in src/wps/wps_upnp.c in more detail.
The inactivity poll was originally supposed to use Data::Nullfunc, but
due to Prism2/2.5/3 firmware issues, this was changed to an empty
Data::Data frame. mac80211 does not have such an issue, so change the
inactivity poll frame to be Data::Nullfunc by default and use the
Data::Data workaround only with Host AP driver.
Previous version was discarding TX status for FromDS data frames, but
those are the exact ones that we need to check for inactivity poll to
work, i.e., they are TX status reports for injected data frames.
In addition, remove the debug printing of TX status for data frame since
that could fill up the debug output if kernel-side filtering cannot be
used with monitor interface.
TX status information for all transmitted data frames is not going to
be sent to hostapd anymore, so the CPU load with high traffic load is
going to be significantly reduced.
If a Registrar tries to configure the AP, but fails to validate the
device password (AP PIN), lock the AP setup after four failures. This
protects the AP PIN against brute force guessing attacks.
This optional configuration parameter can be used to override AP
Settings attributes in M7 similarly to extra_cred option for Credential
attribute(s) in M8.
Do not initialize EAPOL state machine for the STA when hostapd is
configured to use WPS with open or shared WEP networks. This allows the
STA to use EAPOL-Start to indicate it wants to start WPS in such a case
and hostapd does not end up running through EAPOL authentication timeout
and disconnecting the STA if WPS is not used.
There was already code for starting EAPOL state machines based on
received EAPOL packets, but that was not working properly since
portEnabled was not set to TRUE on that code path. This is now fixed,
too.
This operation can now be moved into an external program by configuring
hostapd with wps_cred_processing=1 and skip_cred_build=1. A new
ctrl_iface message (WPS-REG-SUCCESS <Enrollee MAC addr> <UUID-E>) will
be used to notify external programs of each successful registration and
that can be used as a tricker to move from unconfigured to configured
state.
This behaves like the one in wpa_supplicant, i.e., hostapd can be
configured not to process new credentials (AP settings) internally and
instead pass the WPS attributes for an external program to process over
ctrl_iface.
The default interval is now 5 seconds (used to be 1 second for
interactive mode and 2 seconds for wpa_cli -a). The interval can be
changed with -G<seconds> command line option.
The separate Association Comeback Time IE was removed from IEEE 802.11w
and the Timeout Interval IE (from IEEE 802.11r) is used instead. The
editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but
still, the use of Timeout Interval IE is the expected mechanism.
This makes it easier to pass the credential data to external programs
(e.g., Network Manager) for processing. The actual use of this data is
not yet included in hostapd/wpa_supplicant.
