Explicitly validate data_len so that static analyzers do not get

data->phase2_method cannot really be NULL if
eap_fast_init_phase2_method() returns success, but this construction
seems to be too difficult for some static analyzers. While this change
is not really needed in practice, it makes it easier to go through
warnings from such analyzers.

md->curlen cannot indicate full buffer size here since the buffered
data is processed whenever the full block size of data is available.
Avoid invalid warnings from static analyzers on memcpy() outside the
buffer length by verifying that curlen is smaller than block size.

This function can fail in theory since the SHA-1 functions are
allowed to return an error. While this does not really happen in
practice (we would not get this far if SHA-1 does not work), it is
cleaner to include the error handling here to keep static analyzers
happier. [Bug 421]

This has been obsoleted by the more generic Linux WEXT (driver_wext.c)
support. The hostap and madwifi driver wrappers can now be used only
with hostapd. The old station interface remains available in releases up
to 1.x.

The driver wrappers broadcom, iphone, osx, and ralink have not been
maintained for a while and it does not look like they will be in the
future either. As such, remove them from the development branch. The
previous versions will be included in older releases up to 1.x.

The padding validation was done on the last padding-length octets in the
buffer which misses the first padding octet (the last octet is the
padding length). Fix the starting offset for the comparison loop to get
the first octet verified. [Bug 420]

Return number of user input bytes from tlsv1_record_receive() to
move this detail into the proper record layer processing. In addition,
ignore unknown content types at record layer and allow processing to
continue after warning level TLS alerts to provide minimal workaround
for closure alerts.

Instead of trying to remember to add wpa_msg() calls for every possible
path where a STA becomes authorized or unauthorized, use
ap_sta_set_authorized() to send these events more consistently.

Currently, there is no events over the control interface

Use a driver_ndis.c specific initialization function to fill in the
wpa_driver_ops information to make it easier to modify struct
wpa_driver_ops in the future. Being able to build driver_ndis.c
with MSVC was the only reason for having to maintain the same order
of function pointers in struct wpa_driver_ops and for having to
update driver_ndis.c for all changes in that structure.

This code has not been maintained for years and there is no plan on

This is a separate tool for preparing source code files for Doxygen.
It does not need to be distributed with hostap.git and it can now be
downloaded separately from http://w1.fi/tools/kerneldoc2doxygen-hostap.pl

wpa_supplicant_rsn_preauth_scan_results() needs to be called to
update RSN pre-authentication candidates. This cannot be done before
the wpa_supplicant_connect() call on the first association, but when
trying to figure out whether to roam, it is fine to do so for the
case when roaming is skipped.

The GTK is renewed in the hostapd after a MIC attack dissassociation
without informing the driver, causing decryption failures. This patch
sends the new GTK/IGTK to the driver after it is updated by the hostapd.

When the supplicant acts as a registrar to learn the access point
parameters send the credentials to the wpa_cli interface after
receiving the 7th message. This is needed for proper behavior with
wps_cred_processing set to 1 or 2.
Without this patch, after the 7th message you got the WPS-CRED-RECEIVED
notification without the credentials. This was because the cred_attr and
cred_attr_len were not filled in in the wps structure.

In scan.c, merge a channel's noise value into the scan results. When
comparing scan results, compute the signal-to-noise ratio and use it
when available. Prefer a 5 GHz network if its SNR is really big (> 30)
or if its SNR is relatively close to the other network's.
Some stations have been reported to send EAPOL-Key Error Reports
indicating Michael MIC failures even when the cipher is not TKIP
(e.g., when the network is using only CCMP). Ignore such reports
to avoid starting TKIP countermeasures unnecessarily. This can
prevent certaint types of denial of service attacks by insiders,
but mostly this is to work around invalid station implementations.

The eloop timeout to stop TKIP countermeasures has to be canceled

Add a D-Bus signal for EAP SM requests. This signal is emitted on the
Interface object so that clients only have to listen to one object for
requests rather than to all network objects. This signal is analogous
