In this commit, we fix a bug that would cause nodes to be unable to parse a given block from the wire. The block would be properly accepted if fed in via other mechanisms. The issue here is that the old checks for the maximum witness size, circa segwit v0 where placed in the wire package _as well_ as the tx engine. This check should only be in the engine, since it's properly gated by other related scrip validation flags. The fix itself is simple: limit witnesses only based on the maximum block size in bytes, or ~4MB.

@losh11 I can confirm that this diff is the combination of https://github.com/btcsuite/btcd/pull/1896/files and https://github.com/btcsuite/btcd/pull/1907/files, and that these bugs are presently bricking ltcd, and I have tested, and this PR fixes the issues, and is really critical to any apps that use ltcd/wire. Thanks for merging it. |
