c19d3eacc2 CI: verify a symlink has FILE_ATTRIBUTE_NORMAL set
Not that it really makes sense to set FILE_ATTRIBUTE_NORMAL for symlinks in
POSIX client context, but that's what we had before 4.14.

72dcae2f56 vfs: restore platform specific POSIX sys_acl_set_file() functions
92b149954237a445594c993b79a860c63113d54b removed SMB_VFS_SYS_ACL_SET_FILE() and
all the VFS module implementations. But sys_acl_set_file() in vfs_default calls
into sys_acl_set_file() in sysacls.c which calls back into platform specific
modules.

42dbd31f73 dbcheck: Check Deleted Objects and reduce noise in reports about expired tombstones
These reports (about recently deleted objects)
create concern about a perfectly normal part of DB operation.

We must not operate on objects that are expired or we might reanimate them,
but we must fix "Deleted Objects" if it is wrong (mostly it is set as being
deleted in 9999, but in alpha19 we got this wrong).

df0dd2ae00 s3: libsmb: cli_state_save_tcon(). Don't deepcopy tcon struct when temporarily swapping out a connection on a cli_state.
This used to make a deep copy of either
cli->smb2.tcon or cli->smb1.tcon, but this leaves
the original tcon pointer in place which will then get
TALLOC_FREE()'d when the new tree connection is made on
this cli_state.

As there may be pipes open on the old tree connection with
talloc'ed state allocated using the original tcon pointer as a
talloc parent we can't deep copy and then free this pointer
as that will fire the destructors on the pipe memory and
mark them as not connected.

This call is used to temporarily swap out a tcon pointer
(whilst keeping existing pipes open) to allow a new tcon
on the same cli_state and all users correctly call
cli_state_restore_tcon() once they are finished with
the new tree connection.

Just return the existing pointer and set the old value to NULL.
We know we MUST be calling cli_state_restore_tcon() below
to restore the original tcon tree connection pointer before
closing the session.

Remove the knownfail.d entry.

b6a9277bea s3: torture: Change the SMB1-only UID-REGRESSION-TEST to do an explicit copy of the tcon struct in use.
For this test only, explicitly copy the SMB1 tcon struct,
don't use cli_state_save_tcon()//cli_state_restore_tcon()
as these calls will soon change to just manipulate the pointer
to avoid TALLOC_FREE() on the tcon struct which calls
destructors on child pipe data.

In SMB1 this test calls cli_tdis() twice with an invalid
vuid and expects the SMB1 tcon struct to be preserved
across the calls.

SMB1 cli_tdis() frees cli->smb1.tcon so we must put back
a deep copy into cli->smb1.tcon to be able to safely call
cli_tdis() again.

This is a test-only hack. Real client code
uses cli_state_save_tcon()/cli_state_restore_tcon()
if it needs to temporarily swap out the active
tcon on a client connection.

$PREFIX is the the value from --with-selftest-prefix.

The result of the test should not depend on --with-selftest-prefix,
the 'long_path' test in particular.

If the path is to long smbclient (via libarchive) will only
put the full path into a PAX HEADER as 'path' keyword,
that's fine in general, modern tools handle it just fine.
But Perl's Archive::Tar don't handle it and only seems
truncated file names.

I have a fix for Archive::Tar, see:

9d5f5e821c selftest/Samba4: make more use of get_cmd_env_vars()
This simplifies the code a lot and makes it much easier to
add new environment variables in future.

56c2c0f651 selftest:Samba4: avoid File::Path 'make_path' in setup_dns_hub_internal()
While spliting the build and test stages I hit strange permission
problems, when a parent directory is missing,
which can be avoided by using plain mkdir() on each level.

9fed2749c0 Makefile: add support for 'make testonly'
That skips any attempt to recompile before running the tests.
Some times that's useful for debugging and we'll
use it to split the build and test stages in autobuild and gitlab-ci
later.

99673b77b0 s3:idmap_hash: reliable return ID_TYPE_BOTH
idmap_hash used to bounce back the requested type,
which was ID_TYPE_UID, ID_TYPE_GID or ID_TYPE_NOT_SPECIFIED
before as the winbindd parent always used a lookupsids.
When the lookupsids failed because of an unknown domain,
the idmap child weren't requested at all and the caller
sees ID_TYPE_NOT_SPECIFIED.

This module should have supported ID_TYPE_BOTH since
samba-4.1.0, similar to idmap_rid and idmap_autorid.

Now that the winbindd parent will pass ID_TYPE_BOTH in order to
indicate that the domain exists, it's better to always return
ID_TYPE_BOTH instead of a random mix of ID_TYPE_UID, ID_TYPE_GID
or ID_TYPE_BOTH. In order to request a type_hint it will return
ID_REQUIRE_TYPE for ID_TYPE_NOT_SPECIFIED, which means that
the parent at least assures that the domain sid exists.
And the caller still gets ID_TYPE_NOT_SPECIFIED if the
domain doesn't exist.

5041731ca0 s3/auth: implement "winbind:ignore domains"
Under the following conditions a user from an ignored domain might be able to
authenticate:

- using Kerberos

- successfully previous authentication so the idmap and name caches are filled

- winbind not running (fwiw, winbindd is mandatory on a domain member)

- nscd running with a cached getpwnam for the ignored user (otherwise auth fails
  because getpwnam fails)

- lookup_name() function being modified to look into the name cache before
  contacting winbindd. Currently it talks directly to winbindd and that will
  check the cache.

Currently, authentication will only fail because creating the local token for
the user fails because an LSA lookupname RPC call fails (because winbindd is not
running).

All of this makes a successfull authentication unlikelly, but that is more by
accident then by design.

To ensures that if winbindd is not running and as such winbindd itself can not
enforce the restriction, also implement the ignored domains check in the auth
system as a last line of defense.
