From 4fa0f615f286631820316f8c87dd61eda494e203 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Thu, 6 Nov 2003 12:34:04 +0000 Subject: another major bit of restructuring of rpc in Samba4. Mostly moving files around, but also added the first bits of auto-generated code for the lsa pipe. I haven't updated the Makefile to call pidl yet, so for now the code was cut-and-pasted into librpc/ndr/ndr_lsa.c manually (This used to be commit 6b222d3b6541ee74cf8bf3f0913cd444903ca991) --- source4/librpc/idl/lsa.idl | 48 +++ source4/librpc/ndr/libndr.h | 95 +++++ source4/librpc/ndr/ndr.c | 187 ++++++++++ source4/librpc/ndr/ndr_basic.c | 279 ++++++++++++++ source4/librpc/ndr/ndr_echo.c | 114 ++++++ source4/librpc/ndr/ndr_echo.h | 76 ++++ source4/librpc/ndr/ndr_lsa.c | 167 +++++++++ source4/librpc/ndr/ndr_lsa.h | 82 ++++ source4/librpc/ndr/ndr_misc.c | 45 +++ source4/librpc/ndr/ndr_misc.h | 26 ++ source4/librpc/ndr/ndr_sec.c | 309 +++++++++++++++ source4/librpc/ndr/ndr_sec.h | 90 +++++ source4/librpc/rpc/dcerpc.c | 804 ++++++++++++++++++++++++++++++++++++++++ source4/librpc/rpc/dcerpc.h | 129 +++++++ source4/librpc/rpc/dcerpc_smb.c | 320 ++++++++++++++++ source4/librpc/rpc/rpc_echo.c | 137 +++++++ source4/librpc/rpc/rpc_lsa.c | 149 ++++++++ 17 files changed, 3057 insertions(+) create mode 100644 source4/librpc/idl/lsa.idl create mode 100644 source4/librpc/ndr/libndr.h create mode 100644 source4/librpc/ndr/ndr.c create mode 100644 source4/librpc/ndr/ndr_basic.c create mode 100644 source4/librpc/ndr/ndr_echo.c create mode 100644 source4/librpc/ndr/ndr_echo.h create mode 100644 source4/librpc/ndr/ndr_lsa.c create mode 100644 source4/librpc/ndr/ndr_lsa.h create mode 100644 source4/librpc/ndr/ndr_misc.c create mode 100644 source4/librpc/ndr/ndr_misc.h create mode 100644 source4/librpc/ndr/ndr_sec.c create mode 100644 source4/librpc/ndr/ndr_sec.h create mode 100644 source4/librpc/rpc/dcerpc.c create mode 100644 source4/librpc/rpc/dcerpc.h create mode 100644 source4/librpc/rpc/dcerpc_smb.c create mode 100644 source4/librpc/rpc/rpc_echo.c create mode 100644 source4/librpc/rpc/rpc_lsa.c (limited to 'source4/librpc') diff --git a/source4/librpc/idl/lsa.idl b/source4/librpc/idl/lsa.idl new file mode 100644 index 0000000000..566b78f34d --- /dev/null +++ b/source4/librpc/idl/lsa.idl @@ -0,0 +1,48 @@ +/* + lsa interface definition +*/ + +[ uuid(12345778-1234-abcd-ef00-0123456789ab), + version(0.0), + pointer_default(unique) +] interface lsarpc +{ + + typedef struct { + [struct_len] uint32 _len; + uint16 impersonation_level; + uint8 context_mode; + uint8 effective_only; + } lsa_QosInfo; + + typedef struct { + [struct_len] uint32 _len; + uint8 *root_dir; + unistr *object_name; + uint32 attributes; + security_descriptor *sec_desc; + lsa_QosInfo *sec_qos; + } lsa_ObjectAttribute; + + NTSTATUS lsa_OpenPolicy ( + [in] uint16 *system_name, + [in] [ref] lsa_ObjectAttribute *attr, + [in] uint32 desired_access, + [out] policy_handle *handle + ); + + NTSTATUS lsa_OpenPolicy2 ( + [in] unistr *system_name, + [in] [ref] lsa_ObjectAttribute *attr, + [in] uint32 desired_access, + [out] [ref] policy_handle *handle + ); + + NTSTATUS lsa_EnumSids( + [in] [ref] policy_handle *handle, + [in] uint32 start_at, + [in] [out] [ref] uint32 *num_entries, + [out] dom_sid **sids + ); + +} diff --git a/source4/librpc/ndr/libndr.h b/source4/librpc/ndr/libndr.h new file mode 100644 index 0000000000..0d28783a6d --- /dev/null +++ b/source4/librpc/ndr/libndr.h @@ -0,0 +1,95 @@ +/* + Unix SMB/CIFS implementation. + rpc interface definitions + Copyright (C) Andrew Tridgell 2003 + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
