94377fbc52 TDLS: Allow wpa_cli tdls_setup to start renegotiation
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.

ad79dba127 TDLS: Add testing mode for disabling TPK expiration
tdls_testing 0x104 can now be used to disable expiration of TPK
(0x100) and to use a short lifetime when initiating link (0x4).

0c4268eb27 TDLS: Add testing code for concurrent initiation
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.

43291b683c TDLS: Fix higher/lower MAC address check for concurrent init
The logic here was reversed: the STA with lower MAC address is the
one that continues as the initiator.

f0bfbe2a6c TDLS: Replace os_memset() of all peer data with safer approach
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.

a4c3e4b194 TDLS: Move TPK M1 sending to a separate function
Now all there TPK handshake messages are sent in similar functions
and are easier to find from the source code.

2e1d335e44 TDLS: Allow unencrypted network negotiation through wpa_supplicant
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.

9fe6e4b4db TDLS: Clean up and fix Key Lifetime processing
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.

6b192bc346 TDLS: Add new testing modes for TPK lifetime testing
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

40cf22e6ff TDLS: Clear peer entries on association/disassociation
Since the TDLS links are allowed only to STAs that are in the same
BSS with us, clear all peer data whenever the BSS may have changed.

5b0e6ece54 TDLS: Add a special testing feature for changing TDLS behavior
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
