From: Matt Corallo Date: Tue, 9 Jul 2024 20:54:26 +0000 (+0000) Subject: Keep encoding information in `Txt` `RR`s X-Git-Tag: v0.6.0~2 X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=dbe506dceca233de16d32ea30548454a8f65aefe;p=dnssec-prover Keep encoding information in `Txt` `RR`s Sadly `TXT` records can be encoded in many ways (as they're chunked, and chunks can be any size), and are signed in the way in which we receive them on the wire. Thus, we must keep the encoding information we receive on the wire around in `Txt`s to ensure we can validate their signatures. Here we do so, creating a pile of new machinery to store `Txt` data as a series of up-to-255-byte chunks. --- diff --git a/src/query.rs b/src/query.rs index fd99827..e24e52f 100644 --- a/src/query.rs +++ b/src/query.rs @@ -522,7 +522,7 @@ mod tests { assert_eq!(resolved_rrs.len(), 1); if let RR::Txt(txt) = &resolved_rrs[0] { assert_eq!(txt.name.as_str(), "txt_test.dnssec_proof_tests.bitcoin.ninja."); - assert_eq!(txt.data, b"dnssec_prover_test"); + assert_eq!(txt.data.as_vec(), b"dnssec_prover_test"); } else { panic!(); } } } @@ -568,7 +568,7 @@ mod tests { assert_eq!(resolved_rrs.len(), 1); if let RR::Txt(txt) = &resolved_rrs[0] { assert_eq!(txt.name.as_str(), "matt.user._bitcoin-payment.mattcorallo.com."); - assert!(txt.data.starts_with(b"bitcoin:")); + assert!(txt.data.as_vec().starts_with(b"bitcoin:")); } else { panic!(); } } } @@ -594,7 +594,7 @@ mod tests { assert_eq!(resolved_rrs.len(), 1); if let RR::Txt(txt) = &resolved_rrs[0] { assert_eq!(txt.name.as_str(), "cname.wildcard_test.dnssec_proof_tests.bitcoin.ninja."); - assert_eq!(txt.data, b"wildcard_test"); + assert_eq!(txt.data.as_vec(), b"wildcard_test"); } else { panic!(); } } } diff --git a/src/rr.rs b/src/rr.rs index a3839d2..5aa7a57 100644 --- a/src/rr.rs +++ b/src/rr.rs @@ -8,9 +8,10 @@ use alloc::string::String; use alloc::borrow::ToOwned; use alloc::format; -use core::cmp::{self, Ordering}; +use core::cmp::Ordering; use core::fmt; use core::fmt::Write; +use core::num::NonZeroU8; use crate::ser::*; @@ -259,6 +260,126 @@ impl Record for RR { } } +#[derive(Debug, Clone, PartialEq, Eq)] +struct TxtBytePart { + /// The bytes themselves. + /// + /// Bytes at or beyond [`Self::len`] may be filled with garbage and should be ignored. + bytes: [u8; 255], + /// The number of bytes which are to be used. + len: NonZeroU8, +} + +/// The bytes of a [`Txt`] record. +/// +/// They are stored as a series of byte buffers so that we can reconstruct the exact encoding which +/// was used for signatures, however they're really just a simple list of bytes, and the underlying +/// encoding should be ignored. +#[derive(Debug, Clone, PartialEq, Eq)] +pub struct TxtBytes { + /// The series of byte buffers storing the bytes themselves. + chunks: Vec, +} + +impl TxtBytes { + /// Constructs a new [`TxtBytes`] from the given bytes + /// + /// Fails if there are too many bytes to fit in a [`Txt`] record. + pub fn new(bytes: &[u8]) -> Result { + if bytes.len() > 255*255 + 254 { return Err(()); } + let mut chunks = Vec::with_capacity((bytes.len() + 254) / 255); + let mut data_write = &bytes[..]; + while !data_write.is_empty() { + let split_pos = core::cmp::min(255, data_write.len()); + let mut part = TxtBytePart { + bytes: [0; 255], + len: (split_pos as u8).try_into().expect("Cannot be 0 as data_write is not empty"), + }; + part.bytes[..split_pos].copy_from_slice(&data_write[..split_pos]); + chunks.push(part); + data_write = &data_write[split_pos..]; + } + debug_assert_eq!(chunks.len(), (bytes.len() + 254) / 255); + Ok(TxtBytes { chunks }) + } + + /// Gets the total number of bytes represented in this record. + pub fn len(&self) -> usize { + let mut res = 0; + for chunk in self.chunks.iter() { + res += chunk.len.get() as usize; + } + res + } + + /// The length of the bytes when serialized on the wire. + pub fn serialized_len(&self) -> u16 { + let mut len = 0u16; + for chunk in self.chunks.iter() { + len = len.checked_add(1 + chunk.len.get() as u16) + .expect("TxtBytes objects must fit in 2^16 - 1 bytes when serialized"); + } + len + } + + /// Gets the bytes as a flat `Vec` of `u8`s.
