This command makes a clone of an existing AD Domain, but does not join the domain. This allows us to test if the join would work without adding objects to the target DC. The server password will need to be reset for the clone to be any use, see the source4/scripting/devel/chgtdcpass (Based on patches written with Garming Sam) Andrew Bartlett Signed-off-by: Andrew Bartlett <abartlet@samba.org> Signed-off-by: Garming Sam <garming@catalyst.net.nz>
We should never get a secret from a server when we specify DRSUAPI_DRS_SPECIAL_SECRET_PROCESSING This asserts that this is the case. Signed-off-by: Andrew Bartlett <abartlet@samba.org>
This allows the creation of domain clones that have no secrets, and so make it safer to examine databases that demonstrate issues Signed-off-by: Andrew Bartlett <abartlet@samba.org>
…te --local Previously this would only be set when we did server-to-server replication Signed-off-by: Andrew Bartlett <abartlet@samba.org>

The change for https://bugzilla.samba.org/show_bug.cgi?id=7587 ("talloc_autofree_context() in shared libraries and plugins is a bad idea on FreeBSD") (ommit 41b6810) causes the following for sssd on Linux: Stack trace of thread 19667: #0 0x00007f2cab91ff6b __GI_raise (libc.so.6) #1 0x00007f2cab90a5c1 __GI_abort (libc.so.6) #2 0x00007f2cab90a491 __assert_fail_base (libc.so.6) #3 0x00007f2cab9186e2 __GI___assert_fail (libc.so.6) #4 0x00007f2cb10aaca5 k5_mutex_lock (libkrb5.so.3) #5 0x00007f2cb10ab790 k5_mutex_lock (libkrb5.so.3) #6 0x00007f2cb10ab8f5 profile_free_file (libkrb5.so.3) #7 0x00007f2cb10ab983 profile_close_file (libkrb5.so.3) #8 0x00007f2cb10af249 profile_release (libkrb5.so.3) #9 0x00007f2cb10a06c7 k5_os_free_context (libkrb5.so.3) #10 0x00007f2cb1075a9a krb5_free_context (libkrb5.so.3) #11 0x000055cea7cb2dd1 kcm_data_destructor (sssd_kcm) #12 0x00007f2cac153e96 _tc_free_internal (libtalloc.so.2) #13 0x00007f2cac1537b0 _tc_free_internal (libtalloc.so.2) #14 0x00007f2cac1537b0 _tc_free_internal (libtalloc.so.2) #15 0x00007f2cac1537b0 _tc_free_internal (libtalloc.so.2) #16 0x00007f2cac1537b0 _tc_free_internal (libtalloc.so.2) #17 0x00007f2cac14e648 _talloc_free (libtalloc.so.2) #18 0x00007f2cac14c480 talloc_lib_fini (libtalloc.so.2) #19 0x00007f2cb151da96 _dl_fini (ld-linux-x86-64.so.2) #20 0x00007f2cab9226bc __run_exit_handlers (libc.so.6) #21 0x00007f2cab9227ec __GI_exit (libc.so.6) #22 0x00007f2cb030dc61 orderly_shutdown (libsss_util.so) #23 0x00007f2cac365a46 tevent_common_check_signal (libtevent.so.0) #24 0x00007f2cac367975 epoll_event_loop_once (libtevent.so.0) #25 0x00007f2cac365dab std_event_loop_once (libtevent.so.0) #26 0x00007f2cac362098 _tevent_loop_once (libtevent.so.0) #27 0x00007f2cac3622eb tevent_common_loop_wait (libtevent.so.0) #28 0x00007f2cac365d3b std_event_loop_wait (libtevent.so.0) #29 0x00007f2cb030eb37 server_loop (libsss_util.so) #30 0x000055cea7cb29f4 main (sssd_kcm) #31 0x00007f2cab90c1eb __libc_start_main (libc.so.6) #32 0x000055cea7cb2c7a _start (sssd_kcm) We still only register one atexit handler instead of multiple ones like in talloc 2.1.11, but avoids using a library destructor. Bug #7587 seems to be fixed by not using talloc_autofree_context() within samba.

Deleting the previous samdb instance by setting it to None before opening the
backed ldb workaround the problem until we find the real problem here.

The current test uses the dig tool from bind9 but this tool has been rewritten in 9.17.7 to use bind's netmgr functions instead of isc_socket (commit 94b7988efb0f9b96415dd2966e6070450d960263). The problem is that these 'netmgr' functions use libuv internally, and, on systems supporting it, they end up using the sendmmsg() syscall which is not catched by socket wrapper so the test fails. This commit converts the test to python and uses the dnspython module instead of the dig tool. Backtraces follow as reference.

Commit e07f890 broke handling of NT4 domains which lack a DNS domain names. As the dns_name is NULL, talloc_steal(dns_name) returns NULL, which causes _wbint_ListTrustedDomains to return NT_STATUS_NO_MEMORY. To make things worse, at that point the new struct netr_DomainTrust is not yet initialized correctly and the "out->count = n + 1" already increased the array counter at the start of the loop without initializing it. Later when NDR-pushing the result in dcesrv_call_dispatch_local(), the ndr_push() can crash when accesssing the ununitialized values: 2023-12-08T14:07:42.759691+00:00

r->out.domains->array and r->out.domains->count to the end of the function ensures we don't return inconsistent state in case of an error. Also, r->out.domains is already set by the NDR layer, no need to create and assign a struct netr_DomainTrustList object. Using talloc_move() ensures we don't leave dangling pointers. Better to crash reliably on accessing NULL, then accessing some unknown memory via a wild pointer. As talloc_move() can't fail, there's no need to check the return value. And using a struct initializer ensures all members are properly initialized.
