Author: dteske Date: Thu Jun 21 14:55:26 2018 New Revision: 335485 URL: https://svnweb.freebsd.org/changeset/base/335485 Log: MFC r335308: bsdconfig: Fix a bug when editing users The usermgmt API was stomping on a global ($user_gid to be specific) so things would appear to work fine until you tried to make a second pass into the API with the now-tainted variable contents. Fixed by localizing menu-specific contents as to not leak outside API. PR: bin/208774 Reported by: Martin Waschbuesch <martin@waschbuesch.de> Sponsored by: Smule, Inc.
