From 3da9aa6b6792407d57816ec4a4cdfd0b4b3434b8 Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Tue, 26 Sep 2017 14:21:44 +0200 Subject: ctrl: tighten CTRL input parsing Validate that incoming CTRL commands... - have decimal IDs, - return error on trailing characters, - have invalid characters in variable identifiers, - send detailed error messages as reply to the requestor. Adjust ctrl_test.{c,ok}, which best show the change in behavior. Message handling causes log messages on stderr; previously, stderr was empty. Add '[ignore]' in testsuite.at so that the nonempty stderr doesn't cause test failures.
