From 9dabfe49c066301ef75bcfcb089fd308366127c4 Mon Sep 17 00:00:00 2001 From: Johnson Lau Date: Fri, 27 Apr 2018 03:56:29 +0800 Subject: Add constant scriptCode policy in non-segwit scripts This disables OP_CODESEPARATOR in non-segwit scripts (even in an unexecuted branch), and makes a positive FindAndDelete result invalid. This ensures that the scriptCode serialized in SignatureHash() is always the same as the script passing to the EvalScript. --- src/script/script_error.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/script/script_error.h') diff --git a/src/script/script_error.h b/src/script/script_error.h index 3200e9470..6982a087f 100644 --- a/src/script/script_error.h +++ b/src/script/script_error.h @@ -64,6 +64,10 @@ typedef enum ScriptError_t SCRIPT_ERR_WITNESS_UNEXPECTED, SCRIPT_ERR_WITNESS_PUBKEYTYPE, + /* Constant scriptCode */ + SCRIPT_ERR_OP_CODESEPARATOR, + SCRIPT_ERR_SIG_FINDANDDELETE, + SCRIPT_ERR_ERROR_COUNT } ScriptError; -- cgit v1.2.3
