discovery: fix panic in DNS fallback SRV lookup

This commit fixes a bug in LND's DNS seed bootstrap code that could crash the node. The code assumed every record in a DNS response was an SRV record, so a non-SRV record (like a normal A or CNAME record) would cause a panic. The fix safel…

lint: remove redundant loop var copies in test files

This commit is a cleanup-only change that removes unnecessary loop-variable copies in Go test files. Since Go 1.22, loop variables are already scoped per-iteration, so the old `x := x` workarounds are redundant. The change affects only tes…

lnwire: validate MuSig2 nonces in LocalNoncesData decode

This change adds a safety check when LND reads stored MuSig2 cryptographic nonces from disk or network data. Previously, a malformed or all-zero nonce could be loaded silently; now the decoder rejects it. MuSig2 nonces are used in multi-si…

Input validation added to deserialization of cryptographic materialMuSig2 nonce validation now enforced at decode timeNew negative test for all-zero / malformed nonce rejection

lnwire: validate MuSig2 nonce points on wire decode

This change tightens input checking for a special type of cryptographic value (a MuSig2 nonce) that peers send to each other in Lightning Network messages. Before, a peer could send bytes that looked like a nonce but were not valid points …

Input validation added at wire decode boundary for cryptographic public nonce pointsPreviously invalid secp256k1 points accepted in 66-byte MuSig2 nonce field could reach MuSig2 session creationMalformed peer input now rejected with explicit errors before protocol state machine processing

build: add fuzzing infrastructure for security testing

This commit only adds new build options and a test harness for fuzzing (automated security testing). It does not change any existing library code that handles PSBTs or other data, so it cannot by itself introduce a security vulnerability o…

psbt: Add bounds check for non-witness UTXO output index

This commit fixes a validation gap in how the library handles Partially Signed Bitcoin Transactions (PSBTs). A PSBT can include a reference to a previous transaction output (the 'non-witness UTXO') that doesn't actually exist. Before this …
