To me these macros hide more than they clarify. In a lot of places we
already directly check for these flags without those macros. Unify
that.
Also, check for the dosmode bits first, lp_map_* is a bit more effort
to evaluate.

We now have ensured that no conflicting services attempt to start
so we do not need the runtime lookup and so avoid the risk that
the lookup may fail.
This means that any duplicates will be noticed early not just
in a race condition.

Just as we refuse to start NETLOGON except on the DC, we must refuse
to start all of the RPC services that are provided by the AD DC.
Most critically of course this applies to netlogon, lsa and samr.
This avoids the supression of these services being the result of a
runtime epmapper lookup, as if that fails these services can disrupt
service to end users by listening on the same socket as the AD DC
servers.

This demonstration should never be enabled in production, if
echo service is required other software is far better positioned
to provide it. Reflection attacks on echo are a known issue.
This is removed for consistency with the removal of rpcecho, but was
never enabled in the default smb.conf so is mostly harmless.

The rpcecho server in source3 does have samba the sleep() feature that
the s4 version has, but the task architecture is different, so there
is not the same impact. Hoever equally this is not something that
should be enabled on production builds of Samba, so restrict to
selftest builds.

The rpcecho server is useful in development and testing, but should never

This makes LDAP_DIRSYNC_OBJECT_SECURITY the only behaviour provided by
Samba.
Having a second access control system withing the LDAP stack is unsafe
and this layer is incomplete.
The current system gives all accounts that have been given the
GUID_DRS_GET_CHANGES extended right SYSTEM access. Currently in Samba
this equates to full access to passwords as well as "RODC Filtered
attributes" (often used with confidential attributes).
Rather than attempting to correctly filter for secrets (passwords) and
these filtered attributes, as well as preventing search expressions for
both, we leave this complexity to the acl_read module which has this
facility already well tested.
The implication is that callers will only see and filter by attribute
in DirSync that they could without DirSync.

If the client requested FILE_OVERWRITE[_IF], we're implicitly adding
FILE_WRITE_DATA to the open_access_mask in open_file_ntcreate(), but for the
access check we're using access_mask which doesn't contain the additional
right, which means we can end up truncating a file for which the user has
only read-only access via an SD.

With a file "home_nodes" next to "public_addresses" you can assign
public IPs to specific nodes when using the deterministic allocation
algorithm. Whenever the "home node" is up, the IP address will be
assigned to that node, independent of any other deterministic
calculation. The line
192.168.21.254 2
in the file "home_nodes" assigns the IP address to node 2. Only when
node 2 is not able to host IP addresses, 192.168.21.254 undergoes the
normal deterministic IP allocation algorithm.

In the fd_close() fsp->fsp_flags.fstat_before_close code path.
If this is a stream and delete-on-close was set, the
backing object (an xattr from streams_xattr) might
already be deleted so fstat() fails with
NT_STATUS_NOT_FOUND. So if fsp refers to a stream we
ignore the error and only bail for normal files where
an fstat() should still work. NB. We cannot use
fsp_is_alternate_stream(fsp) for this as the base_fsp
has already been closed at this point and so the value
fsp_is_alternate_stream() checks for is already NULL.

Indicate BACKUP_INTENT to vfs_openat(). Why? I have a customer request
who wants to add O_NOATIME in this case to avoid metadata updates when
a backup or virus-checking application comes along.
This does not fully handle BACKUP_INTENT correctly, this would require
become_root() appropriately. We might want to do that later after a
lot of careful security audit, but this patch independently might
already provide some infrastructure for it.

This needs close review. I could not see where we were actually
referencing the original flags in a way that would not be available in
local_flags. The reason for this patch is that I want to pass in
vfs_open_how into open_file(), and the distinction between flags and
local_flags made this significantly harder to understand for me.
The only place where we really used both versions is the DBG_NOTICE in
the last hunk, and this will come back in the next patch.
