Instead of using hardcoded maximum A-MPDU length of 64 kB and no
restrictions on minimum MPDU Start Spacing, use the correct values
reported by the driver.
This is not actually used at all and it looks like the rules for
maintaining the old/new RADIUS configuration are not very clear in the
case the RADIUS client configuration did not change. Consequently, it
is better to just remove this for now and if similar functionality is
ever needed, redesign it to be easier to use without causing hard to
find issues with using freed memory.
Simpler approach to reconfiguring the RADIUS client would involve
just deinitializing the old context unconditionally and initializing
a new one whenever the configuration could have changed.
Use shared functions for converting Primary Device Type between binary
and string formats. In addition, use array of eight octets instead of a
specific structure with multiple fields to reduce code complexity.
Mainly, this is including header files to get definitions for functions
which is good to verify that the parameters match. None of these are
issues that would have shown as incorrect behavior of the program.
This gets rid of previously deprecated driver_ops handlers set_wpa,
set_drop_unencrypted, set_auth_alg, set_mode. The same functionality
can be achieved by using the init/deinit/associate handlers.
These driver wrappers should not be used anymore; WEXT should be used
instead. However, there may still be users stuck on older kernel versions
that may require driver specific wrappers, so the source code still
remains in the repository.
This moves the MTU definition into driver_hostap.c since it was really
meant to be specific to this driver. Since this was the last remaining
definition in hostapd_defs.h, remove that header file as unnecessary.
This code was copied from driver_hostap.c where it is used with the
special wlan#ap interface. It was not supposed to be used to change
the MTU for a normal data interface.
Clean up driver_nl80211.c by gettign rid of the last remaining WEXT use.
This requires that a recent mac80211 version is used to get full protection
in station mode via the authorized flag (IEEE 802.1X PAE).
Clean up driver interface by merging hostapd and wpa_supplicant
specific set_beacon driver_ops into a single one. In addition,
merge set_beacon_int into to the same operation.
If initialization fails, we could potentially try to sendto() on -1
socket which would fail. No point in doing that, so just return early
from the function.
The current MinGW/w32api versions seem to provide all the needed CryptoAPI
functions, so the code for loading these dynamically from the DLL can be
removed.
Need to define the workspace buffer properly to allow compiler to handle
strict aliasing between the incoming unsigned char[64] buffer as an u32
array. The previous version built with strict aliasing enabled can
result in SHA-1 producing incorrect results and consequently, with
4-way handshake failing.
This is based on a report and patch from Dan Williams <dcbw@redhat.com>
but with a different type (the union) used as a fix to avoid needing
extra type casting.
Discovered as part of the investigation of:
https://bugzilla.redhat.com/show_bug.cgi?id=494262#c32
if sha1 is built with gcc without turning off strict aliasing, it will
fail to correctly generate the hashes and will fail its own testcases as
well.

This avoids some issues in cases where the ER has been started and
stopped multiple times on the same address and an AP may have stored
multiple event notification addresses for the same ER. The random
identifier allows the ER to filter out unexpected messages from further
processing.
Do not give the allocated memory to the subscription code since it was
not using it as-is anyway. This makes it easier to understand who owns
the allocation an is responsible of freeing it. This may potentially
fix some memory leaks on error paths.
The WPS 1.0h specification is quite unclear on what exactly should be
used as the MAC Address value in the Credential and AP Settings. It
looks like this should after all be the MAC Address of the Enrollee,
so change Registrar implementation to use that address instead of the
AP BSSID.
In addition, add validation code to the Enrollee implementation to
check the MAC Address value inside Credential (and also inside AP Settings)
to make sure it matches with the Enrollee's own address. However, since
there are deployed implementations that do not follow this interpretation
of the spec, only show the mismatch in debug information to avoid breaking
interoperability with existing devices.
This will need some additional code in wps_er_pbc() to handle PBC mode
enabling for a single AP only. For now, this can only be expected to work
when the ER is connected to a single AP.
