Hi everyone,
Someone can help for adding the ciphersuite " ECDHE_ECDSA_WITH_AES_128_CCM " and "ECDHE_ECDSA_WITH_AES_256_CCM " in openssl? 
I tried adding in the file tls1.h    # define TLS1_CK_ECDHE_ECDSA_WITH_AES_128_CCM            0x0300C0AC
    # define TLS1_CK_ECDHE_ECDSA_WITH_AES_256_CCM            0x0300C0AD
And modifing the file  ssl_ciph.c the functions    ssl_load_ciphers() ... And modifing the file evp_cipher.c and sssl_locl.cand finaly ssl_algs.c.
There are no way to make it works. It continue to give me  error: ssl3_get_client_hello:no shared cipher:s3_srvr.c:1420
