From a2de8a12d3a218f172cf41fbf896ccf2b3bddfc8 Mon Sep 17 00:00:00 2001 From: Simo Sorce Date: Thu, 26 Apr 2012 12:27:05 -0400 Subject: s4-auth-krb: smb_rd_req_return_stuff is used only in gensec_krb5 Make it clearly a gensec_krb5 accessory file. This function should never be used anywhere else. This function was copied out from the Heimdal tree and is kept in a separate file for clarity and to keep the original license boilerplate. --- source4/auth/gensec/gensec_krb5.c | 1 + source4/auth/gensec/gensec_krb5_util.c | 102 +++++++++++++++++++++++++++++++ source4/auth/gensec/gensec_krb5_util.h | 10 +++ source4/auth/gensec/wscript_build | 2 +- source4/auth/kerberos/kerberos_heimdal.c | 102 ------------------------------- source4/auth/kerberos/wscript_build | 2 +- 6 files changed, 115 insertions(+), 104 deletions(-) create mode 100644 source4/auth/gensec/gensec_krb5_util.c create mode 100644 source4/auth/gensec/gensec_krb5_util.h mode change 100644 => 100755 source4/auth/gensec/wscript_build delete mode 100644 source4/auth/kerberos/kerberos_heimdal.c (limited to 'source4/auth') diff --git a/source4/auth/gensec/gensec_krb5.c b/source4/auth/gensec/gensec_krb5.c index 8dde8373a8..6209c2ec4e 100644 --- a/source4/auth/gensec/gensec_krb5.c +++ b/source4/auth/gensec/gensec_krb5.c @@ -41,6 +41,7 @@ #include "lib/util/util_net.h" #include "../lib/util/asn1.h" #include "auth/kerberos/pac_utils.h" +#include "gensec_krb5_util.h" _PUBLIC_ NTSTATUS gensec_krb5_init(void); diff --git a/source4/auth/gensec/gensec_krb5_util.c b/source4/auth/gensec/gensec_krb5_util.c new file mode 100644 index 0000000000..44cb39c518 --- /dev/null +++ b/source4/auth/gensec/gensec_krb5_util.c @@ -0,0 +1,102 @@ +/* + * Copyright (c) 1997 - 2006 Kungliga Tekniska Högskolan + * (Royal Institute of Technology, Stockholm, Sweden). + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * + * 1.
