9530c418a3 s3:smbd: allow anonymous encryption after one authenticated session setup
I have captures where a client tries smb3 encryption on an anonymous session,
we used to allow that before commit da7dcc443f45d07d9963df9daae458fbdd991a47
was released with samba-4.15.0rc1.

Testing against Windows Server 2022 revealed that anonymous signing is always
allowed (with the session key derived from 16 zero bytes) and
anonymous encryption is allowed after one authenticated session setup on
the tcp connection.

aee05f1167 s3/smbd: If we fail to close file_handle ensure we should reset the fd
if fsp_flags.fstat_before_close == true then close_file_smb will call
vfs_stat which can fail. If it does fail then the fd associated
with the file handle will still be set (and we will hit an assert
is the file handle destructor) when calling file_free.
We need to set fd to -1 to avoid that. To achieve that we capture and
return the vfs_stat_fsp failure status while still processing the rest
of the fd_close logic.

72f7086825 smbd: simplify handling of failing fstat() after unlinking file
close_remove_share_mode() already called vfs_stat_fsp(), so we can skip the
fstat() triggered in fd_close() by fsp->fsp_flags.fstat_before_close being true.

This avoids getting an EACCESS error when doing an fstat() on the removed file
which seems to happen with some FUSE filesystems.

bf497819e6 smbd: fix check_any_access_fsp() for non-fsa fsps
smbd_check_access_rights_fsp() requires *all* rights in access_mask to
be granted by the underlying ACL, but the semantics of this function
is supposed to grant access if any one of the rights in
access_requested is allowed.

Fix this by looping over the requested access mask. If
smbd_check_access_rights_fsp() returns sucess, mask will be non-null
and when assigned to access_granted, the subsequent check will pass,
fail otherwise.

I'm not doing an early exit on purpose because a subsequent commit
adds additional security checks that are done in the subsequent code
path common for fsa and non-fsa fsps.

318fd95d5e 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.

We need to decide between calling ctdbd_unregister_ips() by default, as
it means the tcp connection is really gone and ctdb needs to remove the
'tickle' information.  But when a connection was passed to a different
smbd process, we need to use ctdbd_passed_ips() as the tcp connection is
still alive and the 'tickle' information should not be removed within
ctdb.

631e6aa0d0 smbd: bring back "smb3 unix extensions" option
This basically reverts commit b3cae8dcf192f65031f143e5bb9135c895611d98
with a few important differences:

* SMB3 UNIX extensions are always built, but disabled by default at runtime.

* They are globally enabled in the fileserver test environment.

* It's now a per-share option, so admins can selectively disable them
  on a per-share basis. This allows clients to detect early that a share
  doesn't support user mount requested POSIX and fail appropiately, passing
  the failure to the requesting application (mount command).

6e300ef731 smbd: tweak POSIX check in smbd_do_qfilepathinfo()
This check is only needed for SMB2, so check for that, and in the SMB2 codepath
we'll always have a valid fsp, so we can drop that check.

3f73bb591c smbd: leave comment on broken SMB1 POSIX open handling of SMB_O_DIRECT
Since e0814dc5082dd4ecca8a155e0ce24b073158fd92 the passed in attributes get
replaced by the mode in create_file_default().

As FILE_FLAG_NO_BUFFERING is never checked when doing the final IO, it doesn't
really matter.
