struct wpabuf* tls_connection_handshake ( void *  tls_ctx,

tls_connection_handshake - Process TLS handshake (client side) : TLS context data from tls_init() : Connection context data from tls_connection_init() : Input data from TLS server : Pointer to application data pointer, or NULL if dropped Returns: Output data, NULL on failure

The caller is responsible for freeing the returned output data. If the final handshake message includes application data, this is decrypted and appl_data (if not NULL) is set to point this data. The caller is responsible for freeing appl_data.

This function is used during TLS handshake. The first call is done with in_data == NULL and the library is expected to return ClientHello packet. This packet is then send to the server and a response from server is given to TLS library by calling this function again with in_data pointing to the TLS message from the server.

If the TLS handshake fails, this function may return NULL. However, if the TLS library has a TLS alert to send out, that should be returned as the output data. In this case, tls_connection_get_failed() must return failure (> 0).

tls_connection_established() should return 1 once the TLS handshake has been completed successfully.

struct wpabuf* tls_connection_ia_send_phase_finished ( void *  tls_ctx,

struct tls_connection* tls_connection_init ( void *  tls_ctx  )  [read]

)

tls_connection_prf - Use TLS-PRF to derive keying material : TLS context data from tls_init() : Connection context data from tls_connection_init() : Label (e.g., description of the key) for PRF : seed is 0 = client_random|server_random, 1 = server_random|client_random : Buffer for output data from TLS-PRF : Length of the output buffer Returns: 0 on success, -1 on failure

This function is optional to implement if tls_connection_get_keys() provides access to master secret and server/client random values. If these values are not exported from the TLS library, tls_connection_prf() is required so that further keying material can be derived from the master secret. If not implemented, the function will still need to be defined, but it can just return -1. Example implementation of this function is in tls_prf() function when it is called with seed set to client_random|server_random (or server_random|client_random).

tls_global_set_verify - Set global certificate verification options : TLS context data from tls_init() : 0 = do not verify CRLs, 1 = verify CRL for the user certificate, 2 = verify CRL for all certificates Returns: 0 on success, -1 on failure

void* tls_init ( const struct tls_config *  conf  ) 

tls_init - Initialize TLS library : Configuration data for TLS library Returns: Context data to be used as tls_ctx in calls to other functions, or NULL on failure.

Called once during program startup and once for each RSN pre-authentication session. In other words, there can be two concurrent TLS contexts. If global library initialization is needed (i.e., one that is shared between both authentication types), the TLS library wrapper should maintain a reference counter and do global initialization only when moving from 0 to 1 reference.
