lnwallet+walletrpc: add SubmitPackage for v3 CPFP package relay

This commit adds a new RPC called SubmitPackage to LND's WalletKit. It lets users submit a group of related Bitcoin transactions together so a zero-fee parent can be accepted because a later child transaction pays its fee. This is a featur…

This is a large dependency upgrade for the LND Lightning node software. It moves LND from older btcd Bitcoin library packages to new 'v2' packages and updates related wallet and network libraries. The commit is almost entirely mechanical i…

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…

This commit removes an old workaround in LND's dependency file (go.mod) that pinned a safe version of the 'xz' compression library. The workaround was originally added because another dependency once pulled in a vulnerable version of xz. T…

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…

mod: bump kvdb to v1.5.1

This commit updates a dependency version in LND's build files. It bumps the internal 'kvdb' submodule from version 1.5.0 to 1.5.1 so that downstream projects importing kvdb directly do not pull in an older, vulnerable telemetry library (Op…

multi: drop tor v2 onion production, keep wire codec faithful

This commit removes support for obsolete Tor v2 onion addresses from the Lightning Network Daemon (lnd). Tor v2 services were shut down by the Tor network in October 2021, so lnd will no longer create, accept, or dial v2 onion addresses. H…

Removal of deprecated network protocol (Tor v2) reduces attack surface and prevents futile/unsafe dials to unreachable services.Input validation added at operator boundaries (ParseAddressString, parseAddr) to reject v2 .onion addresses with a clear error.On-disk legacy key fallback now validates decrypted key type and rejects non-v3 (RSA1024) keys before passing them to Tor.
