3 months agos3:smbd multichannel: always refresh the network information v4-18-test

s3:smbd multichannel: always refresh the network information

To maintain SMB Multichannel, windows client might periodically query with
FSCTL_QUERY_NETWORK_INTERFACE_INFO to get SMB server's network information,
in my case windows server 2022 would do this every 10 minutes (600 seconds).

Consider a scenario: the network information might have changed between
these queries, some become link down, new interface is link up, network
speed is changed, and etc. So far smbd might not aware of these changes and
still report out-of-date network information to windows client, until we
manually send a SIGHUP to smbd in order to trigger load_interfaces():
smbd_sig_hup_handler() > reload_services () > load_interfaces()
This might be a bit inconvenient because it is hard to decide when should
we manually send a SIGHUP to smbd for refreshing network information.

This patch adds load_interfaces() at fsctl_network_iface_info(), while smbd
received FSCTL_QUERY_NETWORK_INTERFACE_INFO would go through this and refresh
local_interfaces, then respond to client with up-to-date network information;
also refresh num_ifaces to make sure interfaces count is consistent.

s3: smbd: Ignore fstat() error on deleted stream in fd_close().

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.

ctdb-daemon: Call setproctitle_init()

Commit 19c82c19c009eefe975ae95c8b709fc93f5f4c39 changed the behaviour
of prctl_set_comment() so it now calls setproctitle(3bsd) by default.

In some Linux distributions (e.g. Rocky Linux 8.8), this results in
messages like this spamming the logs:

  ctdbd: setproctitle not initialized, please either call setproctitle_init() or link against libbsd-ctor.

Most Samba daemons seem to call setproctitle_init(), so do it here.

In the longer term CTDB should also switch to using lib/util's
process_set_title(), like the rest of Samba, for more flexible process
names.

CVE-2023-4154: Unimplement the original DirSync behaviour without LDAP_DIRSYNC_OBJECT_SECURITY

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.

CVE-2023-42670 s3-rpc_server: Remove cross-check with "samba" EPM lookup

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.

CVE-2023-42670 s3-rpc_server: Strictly refuse to start RPC servers in conflict with AD DC

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.

CVE-2023-42669 s3-rpc_server: Disable rpcecho for consistency with the AD DC

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.

Andrew Bartlett [Tue, 8 Aug 2023 05:58:27 +0000 (17:58 +1200)]
CVE-2023-4154: Unimplement the original DirSync behaviour without LDAP_DIRSYNC_OBJECT_SECURITY

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.
