Release Notes for Samba 4.11.0
|
|
September 17, 2019
|
|
==============================
|
|
|
|
|
|
This is the first stable release of the Samba 4.11 release series.
|
|
Please read the release notes carefully before upgrading.
|
|
|
|
|
|
UPGRADING
|
|
=========
|
|
|
|
AD Database compatibility
|
|
-------------------------
|
|
|
|
Samba 4.11 has changed how the AD database is stored on disk. AD users should
|
|
not really be affected by this change when upgrading to 4.11. However, AD
|
|
users should be extremely careful if they need to downgrade from Samba 4.11 to
|
|
an older release.
|
|
|
|
Samba 4.11 maintains database compatibility with older Samba releases. The
|
|
database will automatically get rewritten in the new 4.11 format when you
|
|
first start the upgraded samba executable.
|
|
|
|
However, when downgrading from 4.11 you will need to manually downgrade the AD
|
|
database yourself. Note that you will need to do this step before you install
|
|
the downgraded Samba packages. For more details, see:
|
|
https://wiki.samba.org/index.php/Downgrading_an_Active_Directory_DC
|
|
|
|
When either upgrading or downgrading, users should also avoid making any
|
|
database modifications between installing the new Samba packages and starting
|
|
the samba executable.
|
|
|
|
SMB1 is disabled by default
|
|
---------------------------
|
|
|
|
The defaults of 'client min protocol' and 'server min protocol'
|
|
have been changed to SMB2_02.
|
|
|
|
This means clients without support for SMB2 or SMB3 are no longer
|
|
able to connect to smbd (by default).
|
|
|
|
It also means client tools like smbclient and other,
|
|
as well as applications making use of libsmbclient are no longer
|
|
able to connect to servers without SMB2 or SMB3 support (by default).
|
|
|
|
It's still possible to allow SMB1 dialects, e.g. NT1, LANMAN2
|
|
and LANMAN1 for client and server, as well as CORE and COREPLUS on
|
|
the client.
|
|
|
|
Note that most commandline tools e.g. smbclient, smbcacls and others
|
|
also support the '--option' argument to overwrite smb.conf options,
|
|
e.g. --option='client min protocol=NT1' might be useful.
|
|
|
|
As Microsoft no longer installs SMB1 support in recent releases
|
|
or uninstalls it after 30 days without usage, the Samba Team
|
|
tries to get remove the SMB1 usage as much as possible.
|
|
|
|
SMB1 is officially deprecated and might be removed step by step
|
|
in the following years. If you have a strong requirement for SMB1

LanMan and plaintext authentication deprecated
|
|
----------------------------------------------
|
|
|
|
The "lanman auth" and "encrypt passwords" parameters are deprecated
|
|
with this release as both are only applicable to SMB1 and are quite
|
|
insecure. NTLM, NTLMv2 and Kerberos authentication are unaffected, as
|
|
"encrypt passwords = yes" has been the default since Samba 3.0.0.
|
|
|
|
If you have a strong requirement for these authentication protocols,
|
|
please file a bug at https://bugzilla.samba.org and let us know about
|
|
the details.
|
|
|
|
BIND9_FLATFILE deprecated
|
|
-------------------------
|
|
|
|
The BIND9_FLATFILE DNS backend is deprecated in this release and will
|
|
be removed in the future. This was only practically useful on a single
|
|
domain controller or under expert care and supervision.
|
|
|
|
This release therefore deprecates the "rndc command" smb.conf
|
|
parameter, which is used to support this configuration. After writing
|
|
out a list of DCs permitted to make changes to the DNS Zone "rndc
|
|
command" is called with reload to tell the 'named' server if a DC was
|
|
added/removed to to the domain.
|
|
|
|
|
|
NEW FEATURES/CHANGES
|
|
====================
|
|
|
|
Default samba process model
|
|
---------------------------
|
|
|
|
The default for the '--model' argument passed to the samba executable has changed
|
|
from 'standard' to 'prefork'. This means a difference in the number of samba
|
|
child processes that are created to handle client connections. The previous
|
|
default would create a separate process for every LDAP or NETLOGON client
|
|
connection. For a network with a lot of persistent client connections, this
|
|
could result in significant memory overhead. Now, with the new default of
|
|
'prefork', the LDAP, NETLOGON, and KDC services will create a fixed number of
|
|
worker processes at startup and share the client connections amongst these
|
|
workers. The number of worker processes can be configured by the 'prefork
|
|
children' setting in the smb.conf (the default is 4).
|
|
|
|
Authentication Logging
|
|
----------------------
|
|
|
|
Winbind now logs PAM_AUTH and NTLM_AUTH events, a new attribute "logonId" has
|
|
been added to the Authentication JSON log messages. This contains a random
|
|
logon id that is generated for each PAM_AUTH and NTLM_AUTH request and is passed
|
|
to SamLogon, linking the windbind and SamLogon requests.
|
|
|
|
The serviceDescription of the messages is set to "winbind", the authDescription
|
|
is set to one of:
|
|
"PASSDB, <command>, <pid>"
|
|
"PAM_AUTH, <command>, <pid>"
|
|
"NTLM_AUTH, <command>, <pid>"
|
|
where:
|
|
<command> is the name of the command makinmg the winbind request i.e. wbinfo
|
|
<pid> is the process id of the requesting process.
|
|
|
|
The version of the JSON Authentication messages has been changed from 1.1 to
|
|
1.2.
|
|
|
|
LDAP referrals
|
|
--------------
|
|
|
|
The scheme of returned LDAP referrals now reflects the scheme of the original
|
|
request, i.e. referrals received via ldap are prefixed with "ldap://"
|
|
and those over ldaps are prefixed with "ldaps://".
|
|
|
|
Previously all referrals were prefixed with "ldap://".
|
|
|
|
Bind9 logging
|
|
-------------
|
|
|
|
It is now possible to log the duration of DNS operations performed by Bind9.
|
|
This should aid future diagnosis of performance issues and could be used to
|
|
monitor DNS performance. The logging is enabled by setting log level to
|
|
"dns:10" in smb.conf.
|
|
|
|
The logs are currently human readable text only, i.e. no JSON formatted output.
|
|
|
|
Log lines are of the form:
|
|
|
|
<function>: DNS timing: result: [<result>] duration: (<duration>)
|
|
zone: [<zone>] name: [<name>] data: [<data>]
|
|
|
|
durations are in microseconds.
|
|
|
|
Default schema updated to 2012_R2
|
|
---------------------------------
|
|
|
|
Default AD schema changed from 2008_R2 to 2012_R2. 2012_R2 functional level
|
|
is not yet available. Older schemas can be used by provisioning with the
|
|
'--base-schema' argument. Existing installations can be updated with the
|
|
samba-tool command "domain schemaupgrade".
|
|
|
|
Samba's replication code has also been improved to handle replication
|
|
with the 2012 schema (the core of this replication fix has also been
|
|
backported to 4.9.11 and will be in a 4.10.x release).
|
|
|
|
For more about how the AD schema relates to overall Windows compatibility,
|
|
please read:
|
|
https://wiki.samba.org/index.php/Windows_2012_Server_compatibility
|
|
|
|
GnuTLS 3.2 required
|
|
-------------------
|
|
|
|
Samba is making efforts to remove in-tree cryptographic functionality,
|
|
and to instead rely on externally maintained libraries. To this end,
|
|
Samba has chosen GnuTLS as our standard cryptographic provider.
|
|
|
|
Samba now requires GnuTLS 3.2 to be installed (including development
|
|
headers at build time) for all configurations, not just the Samba AD
|
|
DC.
|
|
|
|
NOTE WELL: The use of GnuTLS means that Samba will honour the
|
|
system-wide 'FIPS mode' (a reference to the US FIPS-140 cryptographic
|
|
standard) and so will not operate in many still common situations if
|
|
this system-wide parameter is in effect, as many of our protocols rely
|
|
on outdated cryptography.
|
|
|
|
A future Samba version will mitigate this to some extent where good
|
|
cryptography effectively wraps bad cryptography, but for now that above
|
|
applies.
|
|
|
|
samba-tool improvements
|
|
-----------------------
|
|
|
|
A new "samba-tool contact" command has been added to allow the
|
|
command-line manipulation of contacts, as used for address book
|
|
lookups in LDAP.
|
|
|
|
The "samba-tool [user|group|computer|group|contact] edit" command has been
|
|
improved to operate more pleasantly on international character sets.
|
|
|
|
100,000 USER and LARGER Samba AD DOMAINS
|
|
========================================
|
|
|
|
Extensive efforts have been made to optimise Samba for use in
|
|
organisations (for example) targeting 100,000 users, plus 120,000
|
|
computer objects, as well as large number of group memberships.
|
|
|
|
Many of the specific efforts are detailed below, but the net results
|
|
is to remove barriers to significantly larger Samba deployments
|
|
compared to previous releases.
|
|
|
|
Reindex performance improvements
|
|
--------------------------------
|
|
|
|
The performance of samba-tool dbcheck --reindex has been improved,
|
|
especially for large domains.
|
|
|
|
join performance improvements
|
|
-----------------------------
|
|
|
|
The performance of samba-tool domain join has been improved,
|
|
especially for large domains.
|
|
|
|
LDAP Server memory improvements
|
|
-------------------------------
|
|
|
|
The LDAP server has improved memory efficiency, ensuring that large
|
|
LDAP responses (for example a search for all objects) is not copied
|
|
multiple times into memory.
|
|
|
|
Setting lmdb map size
|
|
---------------------
|
|
|
|
It is now possible to set the lmdb map size (the maximum permitted
|
|
size for the database). "samba-tool" now accepts the
|
|
"--backend-store-size" i.e. --backend-store-size=4Gb. If not
|
|
specified it defaults to 8Gb.
|
|
|
|
This option is avaiable for the following sub commands:
|
|
* domain provision
|
|
* domain join
|
|
* domain dcpromo
|
|
* drs clone-dc-database
|
|
|
|
LDB "batch_mode"
|
|
----------------
|
|
|
|
To improve performance during batch operations i.e. joins, ldb now
|
|
accepts a "batch_mode" option. However to prevent any index or
|
|
database inconsistencies if an operation fails, the entire transaction
|
|
will be aborted at commit.
|
|
|
|
New LDB pack format
|
|
-------------------
|
|
|
|
On first use (startup of 'samba' or the first transaction write)
|
|
Samba's sam.ldb will be updated to a new more efficient pack format.
|
|
This will take a few moments.
|
|
|
|
New LDB <= and >= index mode to improve replication performance
|
|
---------------------------------------------------------------
|
|
|
|
As well as a new pack format, Samba's sam.ldb uses a new index format
|
|
allowing Samba to efficiently select objects changed since the last
|
|
replication cycle. This in turn improves performance during
|
|
replication of large domains.
|
|
|
|
https://wiki.samba.org/index.php/LDB_Greater_than_and_Less_than_indexing
|
|
|
|
Improvements to ldb search performance
|
|
--------------------------------------
|
|
|
|
Search performance on large LDB databases has been improved by
|
|
reducing memory allocations made on each object.
|
|
|
|
Improvements to subtree rename performance
|
|
------------------------------------------
|
|
|
|
Improvements have been made to Samba's handling of subtree renames,
|
|
for example of containers and organisational units, however large
|
|
renames are still not recommended.
|
|
|
|
CTDB changes
|
|
============
|
|
|
|
* nfs-linux-kernel-callout now defaults to using systemd service names
|
|
|
|
The Red Hat service names continue to be the default.
|
|
|
|
Other distributions should patch this file when packaging it.
|
|
|
|
* The onnode -o option has been removed
|
|
|
|
* ctdbd logs when it is using more than 90% of a CPU thread
|
|
|
|
ctdbd is single threaded, so can become saturated if it uses the
|
|
full capacity of a CPU thread. To help detect this situation, ctdbd
|
|
now logs messages when CPU utilisation exceeds 90%. Each change in
|
|
CPU utilisation over 90% is logged. A message is also logged when
|
|
CPU utilisation drops below the 90% threshold.
|
|
|
|
* Script configuration variable CTDB_MONITOR_SWAP_USAGE has been removed
|
|
|
|
05.system.script now monitors total memory (i.e. physical memory +
|
|
swap) utilisation using the existing CTDB_MONITOR_MEMORY_USAGE
|
|
script configuration variable.
|
|
|
|
CephFS Snapshot Integration
|
|
---------------------------
|
|
|
|
CephFS snapshots can now be exposed as previous file versions using the new
|
|
ceph_snapshots VFS module. See the vfs_ceph_snapshots(8) man page for details.
|
|
|
|
|
|
REMOVED FEATURES
|
|
================
|
|
|
|
Web server
|
|
----------
|
|
|
|
As a leftover from work related to the Samba Web Administration Tool (SWAT),
|
|
Samba still supported a Python WSGI web server (which could still be turned on
|
|
from the 'server services' smb.conf parameter). This service was unused and has
|
|
now been removed from Samba.
|
|
|
|
samba-tool join subdomain
|
|
-------------------------
|
|
|
|
The subdomain role has been removed from the join command. This option did
|
|
not work and has no tests.
|
|
|
|
Python2 support
|
|
---------------
|
|
|
|
Samba 4.11 will not have any runtime support for Python 2.
|
|
|
|
If you are building Samba using the '--disable-python' option
|
|
(i.e. you're excluding all the run-time Python support), then this
|
|
will continue to work on a system that supports either python2 or
|
|
python3.
|
|
|
|
To build Samba with python2 you *must* set the 'PYTHON' environment
|
|
variable for both the 'configure' and 'make' steps, i.e.
|
|
'PYTHON=python2 ./configure'
|
|
'PYTHON=python2 make'
|
|
This will override the python3 default.
|
|
|
|
Except for this specific build-time use of python2, Samba now requires
|
|
Python 3.4 as a minimum.
|
|
|
|
smb.conf changes
