f5fa824e9a Update OpenSSL 0.9.8 patch for EAP-FAST support
The 0.9.9 branch was for development purposes only, so no one should be
using that in production and there is not much point in maintaining the
obsolete patch here either. Similarly, the old 0.9.8 versions are
obsolete at this point in time and taken into account the recent OpenSSL
vulnerabilities, anything older than 0.9.8za should not really be used.

Prepare an updated version of the TLS session ticket patch based on the
current OpenSSL 0.9.8za release and remove all the older TLS extension
patches.

d4b951f31b Fix offchannel TX not to retransmit pending frame on callback
If the offchannel TX frame command was offloaded to the driver in
offchannel_send_action(), we must not send another copy of the frame if
a remain-on-channel event happens to be delivered between this TX
command and the matching TX status event. It was possible for the
duplicated frame to cause problems, e.g., with P2P invitation exchange
if the same Invitation Request frame got sent twice and only the first
one getting accepted by the peer.

95b6bca66d Add rsn_pairwise bits to set_ieee8021x() driver_ops
This fixes an issue where a driver using the deprecated set_ieee8021x()
callback did not include rsn_pairwise bits in the driver configuration
even if mixed WPA+WPA2 configuration was used. This could result, e.g.,
in CCMP not being enabled properly when wpa_pairwise=TKIP and
rsn_pairwise=CCMP was used in the configuration. Fix this by using
bitwise OR of the wpa_pairwise and rsn_pairwise values to allow the
driver to enable all pairwise ciphers.

In addition, make the newer set_ap() driver_ops use the same bitwise OR
design instead of picking between rsn_pairwise and wpa_pairwise. This
makes the code paths consistent and can also fix issues with mixed mode
configuration with set_ap().

95f6f6a49d RADIUS/EAP server: Use longer username buffer to avoid truncation
If the peer provides a username with large part of it being non-ASCII
characters, the previously used buffers may not have been long enough to
include the full string in debug logs and database search due to forced
truncation of the string by printf_encode(). Avoid this by increasing
the buffer sizes to fit in the maximum result.

5dff6dff63 Fix off-by-one bounds checking in printf_encode()
The off-by-one error in printf_encode() bounds checking could have
allowed buffer overflow with 0x00 being written to the memory position
following the last octet of the target buffer. Since this output is used
as \0-terminated string, the following operation would likely read past
the buffer as well. Either of these operations can result in the process
dying either due to buffer overflow protection or by a read from
unallowed address.

This has been seen to cause wpa_supplicant crash on OpenBSD when control
interface client attaches (debug print shows the client socket address).
Similarly, it may be possible to trigger the issue in RADIUS/EAP server
implementation within hostapd with a suitable constructed user name.

d3d048310c nl80211: Work around error case prints for nl_recvmsgs on Android
I got the below prints on a particular Android platform:

I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20
I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20

In JellyBean libnl_2 code, I see that the nl_recvmsgs returns postive values
too. In some cases, nl_recvmgs return the output of nl_recv function. nl_recv
function can return Number of bytes read, 0 or a negative error code.

Looks like this positive return value for nl_recvmsgs may be specific to
Android. While this is not how the API is supposed to work, this does no
harm with upstream libnl which returns only 0 or -1 from the function.

Couple of code paths in hostapd.c could have left hapd->drv_priv
pointing to memory that was freed in driver_nl80211.c when a secondary
BSS interface is removed. This could result in use of freed memory and
segfault when the next driver operation (likely during interface
deinit/removal). Fix this by clearing hapd->drv_priv when there is
reason to believe that the old value is not valid within the driver
wrapper anymore.

b77aeae732 Interworking: Re-trigger scan if no connect attempt is done
For one specific case when running with Interworking enabled the
re-initialisation of the scan timer is missing. This makes auto connect
to a configured network fail.

The case is:
- Interworking credentials available, but do not match
- Auto interworking is enabled (auto_interworking=1)
- Interworking auto select is disabled (i.e., this is from
  auto_interworking=1, not from INTERWORKING_SELECT auto)
- No configured (enabled and non blacklisted) networks are present
  in scan results list with full match
- Interworking finds matching networks (it does not do full security
  policy match)

This patch covers the case and re-initialises the scan timer to allow
search for a suitable network to continue.
