1599 | * expected that this function is called from the callback set by | |
1600 | * SSL_CTX_set_next_proto_select_cb. | |
1601 | * | |
1602 | * The protocol data is assumed to be a vector of 8-bit, length prefixed byte | |
1603 | * strings. The length byte itself is not included in the length. A byte | |
1604 | * string of length 0 is invalid. No byte string may be truncated. | |
1605 | * | |
1606 | * The current, but experimental algorithm for selecting the protocol is: | |
1607 | * | |
1608 | * 1) If the server doesn't support NPN then this is indicated to the | |
1609 | * callback. In this case, the client application has to abort the connection | |
1610 | * or have a default application level protocol. | |
1611 | * | |
1612 | * 2) If the server supports NPN, but advertises an empty list then the | |
1613 | * client selects the first protcol in its list, but indicates via the | |
1614 | * API that this fallback case was enacted. | |
1615 | * | |
1616 | * 3) Otherwise, the client finds the first protocol in the server's list | |
1617 | * that it supports and selects this protocol. This is because it's | |
1618 | * assumed that the server has better information about which protocol | |
1619 | * a client should use. | |
1620 | * | |
1621 | * 4) If the client doesn't support any of the server's advertised | |
1622 | * protocols, then this is treated the same as case 2. | |
1623 | * | |
1624 | * It returns either | |
1625 | * OPENSSL_NPN_NEGOTIATED if a common protocol was found, or | |
1626 | * OPENSSL_NPN_NO_OVERLAP if the fallback case was reached. | |
