From b5e9ece1f3936d2221480169713042019e34a276 Mon Sep 17 00:00:00 2001 From: Stefan Metzmacher Date: Thu, 24 May 2012 13:46:11 +0200 Subject: s3:smbd: remove global 'smbd_server_conn' !!! For now we still use a global 'global_smbXsrv_connection' in order to pass the connection state to exit_server*(). metze Autobuild-User: Stefan Metzmacher Autobuild-Date: Thu May 24 20:07:20 CEST 2012 on sn-devel-104 --- source3/smbd/globals.c | 11 +---------- source3/smbd/globals.h | 2 +- source3/smbd/process.c | 49 ++++++++++++++++++++++++++++++++++++++++------ source3/smbd/proto.h | 4 +++- source3/smbd/server.c | 29 +++++++-------------------- source3/smbd/server_exit.c | 10 ++++++++-- 6 files changed, 63 insertions(+), 42 deletions(-) diff --git a/source3/smbd/globals.c b/source3/smbd/globals.c index ff8c51bbdf..196b643109 100644 --- a/source3/smbd/globals.c +++ b/source3/smbd/globals.c @@ -102,7 +102,7 @@ struct smbd_parent_context *am_parent = NULL;
