Jason Ish	0623ada24d	dns: better error handling when parsing names The DNS name parser will error out with an error even if the error is incomplete. Instead of manually generating errors, use '?' to let the nom error ripple up the error handling chain. The reason this wasn't done in the first place is this code predates the ? operator, or we were not aware of it at the time. This prevents the case where probing fails when there is enough data to parse the header, but not enough to complete name parser. In such a case a parse error is returned (instead of incomplete) resulting in the payload not being detected as DNS. Ticket #5034	3 years ago

Simon Dugas	7f26246ce1	dns: parse and log fields for SOA record type Added `dns_parse_rdata_soa` to parse SOA fields into an `DNSRDataSOA` struct. Added logging for answer and authority SOA records in both version 1 & 2, as well as grouped formats.	5 years ago
Simon Dugas	af498fd840	dns: use nom's rest to take all remaining rdata Using nom's `rest` combinator eliminates the need to call the do_parse macro for parsing a single element.	5 years ago
Simon Dugas	8005f50647	dns: refactor to handle more rdata formats Represent rdata as `DNSRData` enum variants instead of `Vec<u8>`. This will allow parsing/logging of more complex formats like SOA.	5 years ago

Pierre Chifflier	f3ddd7127c	rust: Add types annotation when required Unfortunately, the transition to nom 5 (and functions instead of macros) has side-effects, one of them being requiring lots of types annotations when using a parsing, for ex in a match instruction.	5 years ago

Jason Ish	40991cab82	rust/dns: handle multiple txt strings Fix handling of TXT records when there are multiple strings in a single TXT record. For now, conform to the C implementation where an answer record is created for each string in a single txt record. Also removes the data_len field from the answer entry. In Rust, the length is available from actual data, which after decoding may actually be different than the encoded data length, so just use the length from the actual data.	8 years ago
