Release Announcements
|
|
=====================
|
|
|
|
This is the first release candidate of Samba 4.4. This is *not*
|
|
intended for production environments and is designed for testing
|
|
purposes only. Please report any defects via the Samba bug reporting
|
|
system at https://bugzilla.samba.org/.
|
|
|
|
Samba 4.4 will be the next version of the Samba suite.
|
|
|
|
|
|
UPGRADING
|
|
=========
|
|
|
|
Nothing special.
|
|
|
|
|
|
NEW FEATURES/CHANGES
|
|
====================
|
|
|
|
Asynchronous flush requests
|
|
---------------------------
|
|
|
|
Flush requests from SMB2/3 clients are handled asynchronously and do
|
|
not block the processing of other requests. Note that 'strict sync'
|
|
has to be set to 'yes' for Samba to honor flush requests from SMB
|
|
clients.
|
|
|
|
s3: smbd
|
|
--------
|
|
|
|
Remove '--with-aio-support' configure option. We no longer would ever prefer
|
|
POSIX-RT aio, use pthread_aio instead.
|
|
|
|
samba-tool sites
|
|
----------------
|
|
|
|
The 'samba-tool sites' subcommand can now be run against another server by
|
|
specifying an LDB URL using the '-H' option and not against the local database
|
|
only (which is still the default when no URL is given).
|
|
|
|
samba-tool domain demote
|
|
------------------------
|
|
|
|
Add '--remove-other-dead-server' option to 'samba-tool domain demote'
|
|
subcommand. The new version of this tool now can remove another DC that is
|
|
itself offline. The '--remove-other-dead-server' removes as many references
|
|
to the DC as possible.
|
|
|
|
samba-tool drs clone-dc-database
|
|
--------------------------------
|
|
|
|
Replicate an initial clone of domain, but do not join it.
|
|
This is developed for debugging purposes, but not for setting up another DC.
|
|
|
|
pdbedit
|
|
-------
|
|
|
|
Add '--set-nt-hash' option to pdbedit to update user password from nt-hash
|
|
hexstring. 'pdbedit -vw' shows also password hashes.
|
|
|
|
smbstatus
|
|
---------
|
|
|
|
'smbstatus' was enhanced to show the state of signing and encryption for
|
|
sessions and shares.
|
|
|
|
smbget
|
|
------
|
|
The -u and -p options for user and password were replaced by the -U option that
|
|
accepts username[%password] as in many other tools of the Samba suite.
|
|
Similary, smbgetrc files do not accept username and password options any more,
|
|
only a single "user" option which also accepts user%password combinations.
|
|
The -P option was removed.
|
|
|
|
s4-rpc_server
|
|
-------------
|
|
|
|
Add a GnuTLS based backupkey implementation.
|
|
|
|
ntlm_auth
|
|
---------
|
|
|
|
Using the '--offline-logon' enables ntlm_auth to use cached passwords when the
|
|
DC is offline.
|
|
|
|
Allow '--password' force a local password check for ntlm-server-1 mode.
|
|
|
|
vfs_offline
|
|
-----------
|
|
|
|
A new VFS module called vfs_offline has been added to mark all files in the
|
|
share as offline. It can be useful for shares mounted on top of a remote file
|
|
system (either through a samba VFS module or via FUSE).
|
|
|
|
KCC
|
|
---
|
|
|
|
The Samba KCC has been improved, but is still disabled by default.
|
|
|
|
DNS
|
|
---
|
|
|
|
There were several improvements concerning the Samba DNS server.
|
|
|
|
Active Directory
|
|
----------------
|
|
|
|
There were some improvements in the Active Directory area.
|
|
|
|
WINS nsswitch module
|
|
--------------------
|
|
|
|
The WINS nsswitch module has been rewritten to address memory issues and to
|
|
simplify the code. The module now uses libwbclient to do WINS queries. This
|
|
means that winbind needs to be running in order to resolve WINS names using
|
|
the nss_wins module. This does not affect smbd.
|
|
|
|
CTDB changes
|
|
------------
|
|
|
|
* CTDB now uses a newly implemented parallel database recovery scheme
|
|
that avoids deadlocks with smbd.
|
|
|
|
In certain circumstances CTDB and smbd could deadlock. The new
|
|
recovery implementation avoid this. It also provides improved
|
|
recovery performance.
|
|
|
|
* All files are now installed into and referred to by the paths
|
|
configured at build time. Therefore, CTDB will now work properly
|
|
when installed into the default location at /usr/local.
|
|
|
|
* Public CTDB header files are no longer installed, since Samba and
|
|
CTDB are built from within the same source tree.
|
|
|
|
* CTDB_DBDIR can now be set to tmpfs[:<tmpfs-options>]
|
|
|
|
This will cause volatile TDBs to be located in a tmpfs. This can
|
|
help to avoid performance problems associated with contention on the
|
|
disk where volatile TDBs are usually stored. See ctdbd.conf(5) for
|
|
more details.
|
|
|
|
* Configuration variable CTDB_NATGW_SLAVE_ONLY is no longer used.
|
|
Instead, nodes should be annotated with the "slave-only" option in
|
|
the CTDB NAT gateway nodes file. This file must be consistent
|
|
across nodes in a NAT gateway group. See ctdbd.conf(5) for more
|
|
details.
|
|
|
|
* New event script 05.system allows various system resources to be
|
|
monitored
|
|
|
|
This can be helpful for explaining poor performance or unexpected
|
|
behaviour. New configuration variables are
|
|
CTDB_MONITOR_FILESYSTEM_USAGE, CTDB_MONITOR_MEMORY_USAGE and
|
|
CTDB_MONITOR_SWAP_USAGE. Default values cause warnings to be
|
|
logged. See the SYSTEM RESOURCE MONITORING CONFIGURATION in
|
|
ctdbd.conf(5) for more information.
|
|
|
|
The memory, swap and filesystem usage monitoring previously found in
|
|
00.ctdb and 40.fs_use is no longer available. Therefore,
|
|
configuration variables CTDB_CHECK_FS_USE, CTDB_MONITOR_FREE_MEMORY,
|
|
CTDB_MONITOR_FREE_MEMORY_WARN and CTDB_CHECK_SWAP_IS_NOT_USED are
|
|
now ignored.
|
|
|
|
* The 62.cnfs eventscript has been removed. To get a similar effect
|
|
just do something like this:
|
|
|
|
mmaddcallback ctdb-disable-on-quorumLoss \
|
|
--command /usr/bin/ctdb \
|
|
--event quorumLoss --parms "disable"
|
|
|
|
mmaddcallback ctdb-enable-on-quorumReached \
|
|
--command /usr/bin/ctdb \
|
|
--event quorumReached --parms "enable"
|
|
|
|
* The CTDB tunable parameter EventScriptTimeoutCount has been renamed
|
|
to MonitorTimeoutCount
|
|
|
|
It has only ever been used to limit timed-out monitor events.
|
|
|
|
Configurations containing CTDB_SET_EventScriptTimeoutCount=<n> will
|
|
cause CTDB to fail at startup. Useful messages will be logged.
|
|
|
|
* The commandline option "-n all" to CTDB tool has been removed.
|
|
|
|
The option was not uniformly implemented for all the commands.
|
|
Instead of command "ctdb ip -n all", use "ctdb ip all".
|
|
|
|
* All CTDB current manual pages are now correctly installed
|
|
|
|
|
|
