The library crates returned eyre reports, so a failure was a string and the session code could not tell a truncated UPDATE from a bad header. Whatever went wrong, the peer got an FSM error or nothing. Each crate now has its own error types: - bgp-primitives: PrefixError, UnknownAfi and UnknownSafi, and EncodeError for every to_wire. - bgp-packet: Message::decode returns a DecodeError naming the NOTIFICATION code, subcode and data for the failure (header errors per section 6.1, OPEN per 6.2, UPDATE per 6.3). InvalidValue and CommunityError replace the remaining strings. from_wire is now a thin wrapper around decode. - bgp-server: SessionError, ServerError and ConfigError. Every abnormal end of a session goes through one function that sends the NOTIFICATION the error maps to. The message length is checked against the 4096-octet maximum before the body is read. - bgp-web: serve returns io::Error. eyre remains in the binary and in tests. Bugs found and fixed on the way: - An OPEN with no optional parameters, which is valid, failed to parse. - An unsupported BGP version was reported as an unknown optional parameter. It now gets Unsupported Version Number with the version we speak as data. - A SAFI above 255 was truncated to its low octet and could match a known one. - Prefix text with a length beyond the address size (10.0.0.0/99) was accepted. - Message::to_wire truncated the body length to 16 bits before checking it. - A peer hold time above 65535 seconds in the configuration wrapped.
