From f722b0743811a4a5caf5288fa901cc8f683b9ffd Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Wed, 8 Nov 2006 01:48:35 +0000 Subject: r19633: Merge to lorikeet-heimdal, removing krb5_rd_req_return_keyblock in favour of a more tasteful replacement. Remove kerberos_verify.c, as we don't need that code any more. Replace with code for using the new krb5_rd_req_ctx() borrowed from Heimdal's accecpt_sec_context.c Andrew Bartlett (This used to be commit 13c9df1d4f0517468c80040d3756310d4dcbdd50) --- source4/heimdal/lib/gssapi/gssapi/gssapi_krb5.h | 2 +- .../heimdal/lib/gssapi/krb5/accept_sec_context.c | 83 ++++-- source4/heimdal/lib/gssapi/krb5/arcfour.c | 30 +-- source4/heimdal/lib/gssapi/krb5/external.c | 10 +- source4/heimdal/lib/gssapi/krb5/gsskrb5_locl.h | 3 +- source4/heimdal/lib/gssapi/krb5/init_sec_context.c | 32 +-- .../lib/gssapi/krb5/inquire_sec_context_by_oid.c | 19 +- .../lib/gssapi/krb5/set_sec_context_option.c | 2 +- source4/heimdal/lib/gssapi/krb5/wrap.c | 1 - source4/heimdal/lib/gssapi/mech/gss_krb5.c | 108 ++++---- source4/heimdal/lib/gssapi/spnego/spnego_locl.h | 4 +- source4/heimdal/lib/krb5/context.c | 18 +- source4/heimdal/lib/krb5/expand_hostname.c | 2 +- source4/heimdal/lib/krb5/krb5-private.h | 5 + source4/heimdal/lib/krb5/krb5-protos.h | 63 ++++- source4/heimdal/lib/krb5/krb5.h | 5 +- source4/heimdal/lib/krb5/rd_req.c | 294 ++++++++++++++++----- 17 files changed, 466 insertions(+), 215 deletions(-) (limited to 'source4/heimdal/lib') diff --git a/source4/heimdal/lib/gssapi/gssapi/gssapi_krb5.h b/source4/heimdal/lib/gssapi/gssapi/gssapi_krb5.h index 8c025c8366..67a9a12bfe 100644 --- a/source4/heimdal/lib/gssapi/gssapi/gssapi_krb5.h +++ b/source4/heimdal/lib/gssapi/gssapi/gssapi_krb5.h @@ -31,7 +31,7 @@ * SUCH DAMAGE. */ -/* $Id: gssapi_krb5.h,v 1.10 2006/10/20 22:04:03 lha Exp $ */ +/* $Id: gssapi_krb5.h,v 1.12 2006/11/05 00:06:09 lha Exp $ */ #ifndef GSSAPI_KRB5_H_ #define GSSAPI_KRB5_H_ diff --git a/source4/heimdal/lib/gssapi/krb5/accept_sec_context.c b/source4/heimdal/lib/gssapi/krb5/accept_sec_context.c index e42bb11b85..6ac80461c3 100644 --- a/source4/heimdal/lib/gssapi/krb5/accept_sec_context.c +++ b/source4/heimdal/lib/gssapi/krb5/accept_sec_context.c @@ -33,7 +33,7 @@ #include "krb5/gsskrb5_locl.h" -RCSID("$Id: accept_sec_context.c,v 1.64 2006/10/25 04:19:45 lha Exp $"); +RCSID("$Id: accept_sec_context.c,v 1.65 2006/11/07 14:52:05 lha Exp $"); HEIMDAL_MUTEX gssapi_keytab_mutex = HEIMDAL_MUTEX_INITIALIZER; krb5_keytab _gsskrb5_keytab; @@ -264,9 +264,7 @@ gsskrb5_acceptor_start(OM_uint32 * minor_status, OM_uint32 ret = GSS_S_COMPLETE; krb5_data indata; krb5_flags ap_options; - krb5_ticket *ticket = NULL; krb5_keytab keytab = NULL; - krb5_keyblock *keyblock = NULL; int is_cfx = 0; const gsskrb5_cred acceptor_cred = (gsskrb5_cred)acceptor_cred_handle; @@ -298,34 +296,65 @@ gsskrb5_acceptor_start(OM_uint32 * minor_status, /* * We need to check the ticket and create the AP-REP packet */ - kret = krb5_rd_req_return_keyblock(_gsskrb5_context, - &ctx->auth_context, - &indata, - (acceptor_cred == NULL) ?
