samba4: updated to 4.10.0
Release Notes for Samba 4.10.0
This is the first stable release of the Samba 4.10 release series.
Please read the release notes carefully before upgrading.
NEW FEATURES/CHANGES
====================
GPO Improvements
----------------
A new 'samba-tool gpo backup' command has been added that can export a
set of Group Policy Objects from a domain in a generalised XML format.
A corresponding 'samba-tool gpo restore' command has been added to
rebuild the Group Policy Objects from the XML after generalization.
(The administrator needs to correct the values of XML entities between
the backup and restore to account for the change in domain).
KDC prefork
-----------
The KDC now supports the pre-fork process model and worker processes will be
forked for the KDC when the pre-fork process model is selected for samba.
Prefork 'prefork children'
--------------------------
The default value for this smdb.conf parameter has been increased from 1 to
4.
Netlogon prefork
----------------
DCERPC now supports pre-forked NETLOGON processes. The netlogon processes are
pre-forked when the prefork process model is selected for samba.
Offline domain backups
----------------------
The 'samba-tool domain backup' command has been extended with a new 'offline'
option. This safely creates a backup of the local DC's database directly from
disk. The main benefits of an offline backup are it's quicker, it stores more
database details (for forensic purposes), and the samba process does not have
to be running when the backup is made. Refer to the samba-tool help for more
details on using this command.
Group membership statistics
---------------------------
A new 'samba-tool group stats' command has been added. This provides summary
information about how the users are spread across groups in your domain.
The 'samba-tool group list --verbose' command has also been updated to include
the number of users in each group.
Paged results LDAP control
--------------------------
The behaviour of the paged results control (1.2.840.113556.1.4.319, RFC2696)
has been changed to more closely match Windows servers, to improve memory
usage. Paged results may be used internally (or is requested by the user) by
LDAP libraries or tools that deal with large result sizes, for example, when
listing all the objects in the database.
Previously, results were returned as a snapshot of the database but now,
some changes made to the set of results while paging may be reflected in the
responses. If strict inter-record consistency is required in answers (which is
not possible on Windows with large result sets), consider avoiding the paged
results control or alternatively, it might be possible to enforce restrictions
using the LDAP filter expression.
For further details see https://wiki.samba.org/index.php/Paged_Results
Prefork process restart
-----------------------
The pre-fork process model now restarts failed processes. The delay between
restart attempts is controlled by the "prefork backoff increment" (default = 10)
and "prefork maximum backoff" (default = 120) smbd.conf parameters. A linear
back off strategy is used with "prefork backoff increment" added to the
delay between restart attempts up until it reaches "prefork maximum backoff".
Using the default sequence the restart delays (in seconds) are:
0, 10, 20, ..., 120, 120, ...
Standard process model
----------------------
When using the standard process model samba forks a new process to handle ldap
and netlogon connections. Samba now honours the 'max smbd processes' smb.conf
parameter. The default value of 0, indicates there is no limit. The limit
is applied individually to netlogon and ldap. When the process limit is
exceeded Samba drops new connections immediately.
python3 support
---------------
This is the first release of Samba which has full support for Python 3.
Samba 4.10 still has support for Python 2, however, Python 3 will be used by
default, i.e. 'configure' & 'make' will execute using 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.
Alternatively, it is possible to produce Samba Python bindings for both
Python 2 and Python 3. To do so, specify '--extra-python=/usr/bin/python2'
as part of the 'configure' command. Note that python3 will still be used as
the default in this case.
Note that Samba 4.10 supports Python 3.4 onwards.
Future Python support
---------------------
Samba 4.10 will be the last release that comes with full support for
Python 2. Unfortunately, the Samba Team doesn't have the resources to support
both Python 2 and Python 3 long-term.
Samba 4.11 will not have any runtime support for Python 2. This means if
you use Python 2 bindings it is time to migrate to Python 3 now.
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.
Also note that Samba 4.11 will most likely only support Python 3.6 onwards.
JSON logging
------------
Authentication messages now contain the Windows Event Id "eventId" and logon
type "logonType". The supported event codes and logon types are:
Event codes:
4624 Successful logon
4625 Unsuccessful logon
Logon Types:
2 Interactive
3 Network
8 NetworkCleartext
The version number for Authentication messages is now 1.1, changed from 1.0
Password change messages now contain the Windows Event Id "eventId", the
supported event Id's are:
4723 Password changed
4724 Password reset
The version number for PasswordChange messages is now 1.1, changed from 1.0
Group membership change messages now contain the Windows Event Id "eventId",
the supported event Id's are:
4728 A member was added to a security enabled global group
4729 A member was removed from a security enabled global group
4732 A member was added to a security enabled local group
4733 A member was removed from a security enabled local group
4746 A member was added to a security disabled local group
4747 A member was removed from a security disabled local group
4751 A member was added to a security disabled global group
4752 A member was removed from a security disabled global group
4756 A member was added to a security enabled universal group
4757 A member was removed from a security enabled universal group
4761 A member was added to a security disabled universal group
4762 A member was removed from a security disabled universal group
The version number for GroupChange messages is now 1.1, changed from 1.0. Also
A GroupChange message is generated when a new user is created to log that the
user has been added to their primary group.
The leading "JSON <message type>:" and source file prefix of the JSON formatted
log entries has been removed to make the parsing of the JSON log messages
easier. JSON log entries now start with 2 spaces followed by an opening brace
i.e. " {"
SMBv2 samba-tool support
------------------------
On previous releases, some samba-tool commands would not work against a remote
DC that had SMBv1 disabled. SMBv2 support has now been added for samba-tool.
The affected commands are 'samba-tool domain backup|rename' and the
'samba-tool gpo' set of commands.
New glusterfs_fuse VFS module
-----------------------------
The new vfs_glusterfs_fuse module improves performance when Samba
accesses a glusterfs volume mounted via FUSE (Filesystem in Userspace
as part of the Linux kernel). It achieves that by leveraging a
mechanism to retrieve the appropriate case of filenames by querying a
specific extended attribute in the filesystem. No extra configuration
is required to use this module, only glusterfs_fuse needs to be set in
the "vfs objects" parameter. Further details can be found in the
vfs_glusterfs_fuse(8) manpage. This new vfs_glusterfs_fuse module does
not replace the existing vfs_glusterfs module, it just provides an
additional, alternative mechanism to access a Gluster volume.
REMOVED FEATURES
================
MIT Kerberos build of the AD DC
-------------------------------
While not removed, the MIT Kerberos build of the Samba AD DC is still
considered experimental. Because Samba will not issue security
patches for this configuration, such builds now require the explicit
configure option: --with-experimental-mit-ad-dc
For further details see
https://wiki.samba.org/index.php/Running_a_Samba_AD_DC_with_MIT_Kerberos_KDC
samba_backup
------------
The samba_backup script has been removed. This has now been replaced by the
'samba-tool domain backup offline' command.
SMB client Python bindings
--------------------------
The SMB client python bindings are now deprecated and will be removed in future
Samba releases. This will only affects users that may have used the Samba
Python bindings to write their own utilities, i.e. users with a custom Python
script that includes the line 'from samba import smb'.

samba4: updated to 4.12.0
samba 4.12.0:
NEW FEATURES/CHANGES
====================
Python 3.5 Required
-------------------
Samba's minimum runtime requirement for python was raised to Python
3.4 with samba 4.11. Samba 4.12 raises this minimum version to Python
3.5 both to access new features and because this is the oldest version
we test with in our CI infrastructure.
(Build time support for the file server with Python 2.6 has not
changed)
Removing in-tree cryptography: GnuTLS 3.4.7 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 3.4.7 to be installed (including development
headers at build time) for all configurations, not just the Samba AD
DC.
Thanks to this work Samba no longer ships an in-tree DES
implementation and on GnuTLS 3.6.5 or later Samba will include no
in-tree cryptography other than the MD4 hash and that
implemented in our copy of Heimdal.
Using GnuTLS for SMB3 encryption you will notice huge performance and copy
speed improvements. Tests with the CIFS Kernel client from Linux Kernel 5.3
show a 3x speed improvement for writing and a 2.5x speed improvement for reads!
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.
zlib library is now required to build Samba
-------------------------------------------
Samba no longer includes a local copy of zlib in our source tarball.
By removing this we do not need to ship (even where we did not
build) the old, broken zip encryption code found there.
New Spotlight backend for Elasticsearch
---------------------------------------
Support for the macOS specific Spotlight search protocol has been enhanced
significantly. Starting with 4.12 Samba supports using Elasticsearch as search
backend. Various new parameters have been added to configure this:
spotlight backend = noindex | elasticsearch | tracker
elasticsearch:address = ADDRESS
elasticsearch:port = PORT
elasticsearch:use tls = BOOLEAN
elasticsearch:index = INDEXNAME
elasticsearch:mappings = PATH
elasticsearch:max results = NUMBER
Samba also ships a Spotlight client command "mdfind" which can be used to search
any SMB server that runs the Spotlight RPC service. See the manpage of mdfind
for details.
Note that when upgrading existing installations that are using the previous
default Spotlight backend Gnome Tracker must explicitly set "spotlight backend =
tracker" as the new default is "noindex".
'net ads kerberos pac save' and 'net eventlog export'
-----------------------------------------------------
The 'net ads kerberos pac save' and 'net eventlog export' tools will
no longer silently overwrite an existing file during data export. If
the filename given exits, an error will be shown.
Fuzzing
-------
A large number of fuzz targets have been added to Samba, and Samba has
been registered in Google's oss-fuzz cloud fuzzing service. In
particular, we now have good fuzzing coverage of our generated NDR
parsing code.
A large number of issues have been found and fixed thanks to this
effort.
'samba-tool' improvements add contacts as member to groups
----------------------------------------------------------
Previously 'samba-tool group addmemers' can just add users, groups and
computers as members to groups. But also contacts can be members of
groups. Samba 4.12 adds the functionality to add contacts to
groups. Since contacts have no sAMAccountName, it's possible that
there are more than one contact with the same name in different
organizational units. Therefore it's necessary to have an option to
handle group members by their DN.
To get the DN of an object there is now the "--full-dn" option available
for all necessary commands.
The MS Windows UI allows to search for specific types of group members
when searching for new members for a group. This feature is included
here with the new samba-tool group addmembers "--object-type=OBJECTYPE"
option. The different types are selected accordingly to the Windows
UI. The default samba-toole behaviour shouldn't be changed.
Allow filtering by OU or subtree in samba-tool
----------------------------------------------
A new "--base-dn" and "--member-base-dn" option is added to relevant
samba-tool user, group and ou management commands to allow operation
on just one part of the AD tree, such as a single OU.
VFS
===
SMB_VFS_NTIMES
--------------
Samba now uses a sentinel value based on utimensat(2) UTIME_OMIT to denote
to-be-ignored timestamp variables passed to the SMB_VFS_NTIMES() VFS function.
VFS modules can check whether any of the time values inside a struct
smb_file_time is to be ignored by calling is_omit_timespec() on the value.
'io_uring' vfs module
---------------------
The module makes use of the new io_uring infrastructure
(intruduced in Linux 5.1), see https://lwn.net/Articles/776703/
Currently this implements SMB_VFS_{PREAD,PWRITE,FSYNC}_SEND/RECV
and avoids the overhead of the userspace threadpool in the default
vfs backend. See also vfs_io_uring(8).
In order to build the module you need the liburing userspace library
and its developement headers installed, see
https://git.kernel.dk/cgit/liburing/
At runtime you'll need a Linux kernel with version 5.1 or higher.
Note that 5.4.14 and 5.4.15 have a regression that breaks the Samba
module! The regression was fixed in Linux 5.4.16 again.
MS-DFS changes in the VFS
-------------------------
This release changes set getting and setting of MS-DFS redirects
on the filesystem to go through two new VFS functions:
SMB_VFS_CREATE_DFS_PATHAT()
SMB_VFS_READ_DFS_PATHAT()
instead of smbd explicitly storing MS-DFS redirects inside
symbolic links on the filesystem. The underlying default
implementations of this has not changed, the redirects are
still stored inside symbolic links on the filesystem, but
moving the creation and reading of these links into the VFS
as first-class functions now allows alternate methods of
storing them (maybe in extended attributes) for OEMs who
don't want to mis-use filesystem symbolic links in this
way.
CTDB changes
============
* The ctdb_mutex_fcntl_helper periodically re-checks the lock file
The re-check period is specified using a 2nd argument to this
helper. The default re-check period is 5s.
If the file no longer exists or the inode number changes then the
helper exits. This triggers an election.
REMOVED FEATURES
================
The smb.conf parameter "write cache size" has been removed.
Since the in-memory write caching code was written, our write path has
changed significantly. In particular we have gained very flexible
support for async I/O, with the new linux io_uring interface in
development. The old write cache concept which cached data in main
memory followed by a blocking pwrite no longer gives any improvement
on modern systems, and may make performance worse on memory-contrained
systems, so this functionality should not be enabled in core smbd
code.
In addition, it complicated the write code, which is a performance
critical code path.
If required for specialist purposes, it can be recreated as a VFS
module.
Retiring DES encryption types in Kerberos.
------------------------------------------
With this release, support for DES encryption types has been removed from
Samba, and setting DES_ONLY flag for an account will cause Kerberos
authentication to fail for that account (see RFC-6649).
Samba-DC: DES keys no longer saved in DB.
-----------------------------------------
When a new password is set for an account, Samba DC will store random keys
in DB instead of DES keys derived from the password. If the account is being
migrated to Windbows or to an older version of Samba in order to use DES keys,
the password must be reset to make it work.
Heimdal-DC: removal of weak-crypto.
-----------------------------------
Following removal of DES encryption types from Samba, the embedded Heimdal
build has been updated to not compile weak crypto code (HEIM_WEAK_CRYPTO).
vfs_netatalk: The netatalk VFS module has been removed.
-------------------------------------------------------
The netatalk VFS module has been removed. It was unmaintained and is not needed
any more.
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 removes the 'rndc command' smb.conf parameter, which
supported this configuration by writing out a list of DCs permitted to
make changes to the DNS Zone and nudging the 'named' server if a new
DC was added to the domain. Administrators using BIND9_FLATFILE will
need to maintain this manually from now on.

samba4: updated to 4.10.0
Release Notes for Samba 4.10.0
This is the first stable release of the Samba 4.10 release series.
Please read the release notes carefully before upgrading.
NEW FEATURES/CHANGES
====================
GPO Improvements
----------------
A new 'samba-tool gpo backup' command has been added that can export a
set of Group Policy Objects from a domain in a generalised XML format.
A corresponding 'samba-tool gpo restore' command has been added to
rebuild the Group Policy Objects from the XML after generalization.
(The administrator needs to correct the values of XML entities between
the backup and restore to account for the change in domain).
KDC prefork
-----------
The KDC now supports the pre-fork process model and worker processes will be
forked for the KDC when the pre-fork process model is selected for samba.
Prefork 'prefork children'
--------------------------
The default value for this smdb.conf parameter has been increased from 1 to
4.
Netlogon prefork
----------------
DCERPC now supports pre-forked NETLOGON processes. The netlogon processes are
pre-forked when the prefork process model is selected for samba.
Offline domain backups
----------------------
The 'samba-tool domain backup' command has been extended with a new 'offline'
option. This safely creates a backup of the local DC's database directly from
disk. The main benefits of an offline backup are it's quicker, it stores more
database details (for forensic purposes), and the samba process does not have
to be running when the backup is made. Refer to the samba-tool help for more
details on using this command.
Group membership statistics
---------------------------
A new 'samba-tool group stats' command has been added. This provides summary
information about how the users are spread across groups in your domain.
The 'samba-tool group list --verbose' command has also been updated to include
the number of users in each group.
Paged results LDAP control
--------------------------
The behaviour of the paged results control (1.2.840.113556.1.4.319, RFC2696)
has been changed to more closely match Windows servers, to improve memory
usage. Paged results may be used internally (or is requested by the user) by
LDAP libraries or tools that deal with large result sizes, for example, when
listing all the objects in the database.
Previously, results were returned as a snapshot of the database but now,
some changes made to the set of results while paging may be reflected in the
responses. If strict inter-record consistency is required in answers (which is
not possible on Windows with large result sets), consider avoiding the paged
results control or alternatively, it might be possible to enforce restrictions
using the LDAP filter expression.
For further details see https://wiki.samba.org/index.php/Paged_Results
Prefork process restart
-----------------------
The pre-fork process model now restarts failed processes. The delay between
restart attempts is controlled by the "prefork backoff increment" (default = 10)
and "prefork maximum backoff" (default = 120) smbd.conf parameters. A linear
back off strategy is used with "prefork backoff increment" added to the
delay between restart attempts up until it reaches "prefork maximum backoff".
Using the default sequence the restart delays (in seconds) are:
0, 10, 20, ..., 120, 120, ...
Standard process model
----------------------
When using the standard process model samba forks a new process to handle ldap
and netlogon connections. Samba now honours the 'max smbd processes' smb.conf
parameter. The default value of 0, indicates there is no limit. The limit
is applied individually to netlogon and ldap. When the process limit is
exceeded Samba drops new connections immediately.
python3 support
---------------
This is the first release of Samba which has full support for Python 3.
Samba 4.10 still has support for Python 2, however, Python 3 will be used by
default, i.e. 'configure' & 'make' will execute using 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.
Alternatively, it is possible to produce Samba Python bindings for both
Python 2 and Python 3. To do so, specify '--extra-python=/usr/bin/python2'
as part of the 'configure' command. Note that python3 will still be used as
the default in this case.
Note that Samba 4.10 supports Python 3.4 onwards.
Future Python support
---------------------
Samba 4.10 will be the last release that comes with full support for
Python 2. Unfortunately, the Samba Team doesn't have the resources to support
both Python 2 and Python 3 long-term.
Samba 4.11 will not have any runtime support for Python 2. This means if
you use Python 2 bindings it is time to migrate to Python 3 now.
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.
Also note that Samba 4.11 will most likely only support Python 3.6 onwards.
JSON logging
------------
Authentication messages now contain the Windows Event Id "eventId" and logon
type "logonType". The supported event codes and logon types are:
Event codes:
4624 Successful logon
4625 Unsuccessful logon
Logon Types:
2 Interactive
3 Network
8 NetworkCleartext
The version number for Authentication messages is now 1.1, changed from 1.0
Password change messages now contain the Windows Event Id "eventId", the
supported event Id's are:
4723 Password changed
4724 Password reset
The version number for PasswordChange messages is now 1.1, changed from 1.0
Group membership change messages now contain the Windows Event Id "eventId",
the supported event Id's are:
4728 A member was added to a security enabled global group
4729 A member was removed from a security enabled global group
4732 A member was added to a security enabled local group
4733 A member was removed from a security enabled local group
4746 A member was added to a security disabled local group
4747 A member was removed from a security disabled local group
4751 A member was added to a security disabled global group
4752 A member was removed from a security disabled global group
4756 A member was added to a security enabled universal group
4757 A member was removed from a security enabled universal group
4761 A member was added to a security disabled universal group
4762 A member was removed from a security disabled universal group
The version number for GroupChange messages is now 1.1, changed from 1.0. Also
A GroupChange message is generated when a new user is created to log that the
user has been added to their primary group.
The leading "JSON <message type>:" and source file prefix of the JSON formatted
log entries has been removed to make the parsing of the JSON log messages
easier. JSON log entries now start with 2 spaces followed by an opening brace
i.e. " {"
SMBv2 samba-tool support
------------------------
On previous releases, some samba-tool commands would not work against a remote
DC that had SMBv1 disabled. SMBv2 support has now been added for samba-tool.
The affected commands are 'samba-tool domain backup|rename' and the
'samba-tool gpo' set of commands.
New glusterfs_fuse VFS module
-----------------------------
The new vfs_glusterfs_fuse module improves performance when Samba
accesses a glusterfs volume mounted via FUSE (Filesystem in Userspace
as part of the Linux kernel). It achieves that by leveraging a
mechanism to retrieve the appropriate case of filenames by querying a
specific extended attribute in the filesystem. No extra configuration
is required to use this module, only glusterfs_fuse needs to be set in
the "vfs objects" parameter. Further details can be found in the
vfs_glusterfs_fuse(8) manpage. This new vfs_glusterfs_fuse module does
not replace the existing vfs_glusterfs module, it just provides an
additional, alternative mechanism to access a Gluster volume.
REMOVED FEATURES
================
MIT Kerberos build of the AD DC
-------------------------------
While not removed, the MIT Kerberos build of the Samba AD DC is still
considered experimental. Because Samba will not issue security
patches for this configuration, such builds now require the explicit
configure option: --with-experimental-mit-ad-dc
For further details see
https://wiki.samba.org/index.php/Running_a_Samba_AD_DC_with_MIT_Kerberos_KDC
samba_backup
------------
The samba_backup script has been removed. This has now been replaced by the
'samba-tool domain backup offline' command.
SMB client Python bindings
--------------------------
The SMB client python bindings are now deprecated and will be removed in future
Samba releases. This will only affects users that may have used the Samba
Python bindings to write their own utilities, i.e. users with a custom Python
script that includes the line 'from samba import smb'.

samba4: updated to 4.10.0
Release Notes for Samba 4.10.0
This is the first stable release of the Samba 4.10 release series.
Please read the release notes carefully before upgrading.
NEW FEATURES/CHANGES
====================
GPO Improvements
----------------
A new 'samba-tool gpo backup' command has been added that can export a
set of Group Policy Objects from a domain in a generalised XML format.
A corresponding 'samba-tool gpo restore' command has been added to
rebuild the Group Policy Objects from the XML after generalization.
(The administrator needs to correct the values of XML entities between
the backup and restore to account for the change in domain).
KDC prefork
-----------
The KDC now supports the pre-fork process model and worker processes will be
forked for the KDC when the pre-fork process model is selected for samba.
Prefork 'prefork children'
--------------------------
The default value for this smdb.conf parameter has been increased from 1 to
4.
Netlogon prefork
----------------
DCERPC now supports pre-forked NETLOGON processes. The netlogon processes are
pre-forked when the prefork process model is selected for samba.
Offline domain backups
----------------------
The 'samba-tool domain backup' command has been extended with a new 'offline'
option. This safely creates a backup of the local DC's database directly from
disk. The main benefits of an offline backup are it's quicker, it stores more
database details (for forensic purposes), and the samba process does not have
to be running when the backup is made. Refer to the samba-tool help for more
details on using this command.
Group membership statistics
---------------------------
A new 'samba-tool group stats' command has been added. This provides summary
information about how the users are spread across groups in your domain.
The 'samba-tool group list --verbose' command has also been updated to include
the number of users in each group.
Paged results LDAP control
--------------------------
The behaviour of the paged results control (1.2.840.113556.1.4.319, RFC2696)
has been changed to more closely match Windows servers, to improve memory
usage. Paged results may be used internally (or is requested by the user) by
LDAP libraries or tools that deal with large result sizes, for example, when
listing all the objects in the database.
Previously, results were returned as a snapshot of the database but now,
some changes made to the set of results while paging may be reflected in the
responses. If strict inter-record consistency is required in answers (which is
not possible on Windows with large result sets), consider avoiding the paged
results control or alternatively, it might be possible to enforce restrictions
using the LDAP filter expression.
For further details see https://wiki.samba.org/index.php/Paged_Results
Prefork process restart
-----------------------
The pre-fork process model now restarts failed processes. The delay between
restart attempts is controlled by the "prefork backoff increment" (default = 10)
and "prefork maximum backoff" (default = 120) smbd.conf parameters. A linear
back off strategy is used with "prefork backoff increment" added to the
delay between restart attempts up until it reaches "prefork maximum backoff".
Using the default sequence the restart delays (in seconds) are:
0, 10, 20, ..., 120, 120, ...
Standard process model
----------------------
When using the standard process model samba forks a new process to handle ldap
and netlogon connections. Samba now honours the 'max smbd processes' smb.conf
parameter. The default value of 0, indicates there is no limit. The limit
is applied individually to netlogon and ldap. When the process limit is
exceeded Samba drops new connections immediately.
python3 support
---------------
This is the first release of Samba which has full support for Python 3.
Samba 4.10 still has support for Python 2, however, Python 3 will be used by
default, i.e. 'configure' & 'make' will execute using 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.
Alternatively, it is possible to produce Samba Python bindings for both
Python 2 and Python 3. To do so, specify '--extra-python=/usr/bin/python2'
as part of the 'configure' command. Note that python3 will still be used as
the default in this case.
Note that Samba 4.10 supports Python 3.4 onwards.
Future Python support
---------------------
Samba 4.10 will be the last release that comes with full support for
Python 2. Unfortunately, the Samba Team doesn't have the resources to support
both Python 2 and Python 3 long-term.
Samba 4.11 will not have any runtime support for Python 2. This means if
you use Python 2 bindings it is time to migrate to Python 3 now.
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.
Also note that Samba 4.11 will most likely only support Python 3.6 onwards.
JSON logging
------------
Authentication messages now contain the Windows Event Id "eventId" and logon
type "logonType". The supported event codes and logon types are:
Event codes:
4624 Successful logon
4625 Unsuccessful logon
Logon Types:
2 Interactive
3 Network
8 NetworkCleartext
The version number for Authentication messages is now 1.1, changed from 1.0
Password change messages now contain the Windows Event Id "eventId", the
supported event Id's are:
4723 Password changed
4724 Password reset
The version number for PasswordChange messages is now 1.1, changed from 1.0
Group membership change messages now contain the Windows Event Id "eventId",
the supported event Id's are:
4728 A member was added to a security enabled global group
4729 A member was removed from a security enabled global group
4732 A member was added to a security enabled local group
4733 A member was removed from a security enabled local group
4746 A member was added to a security disabled local group
4747 A member was removed from a security disabled local group
4751 A member was added to a security disabled global group
4752 A member was removed from a security disabled global group
4756 A member was added to a security enabled universal group
4757 A member was removed from a security enabled universal group
4761 A member was added to a security disabled universal group
4762 A member was removed from a security disabled universal group
The version number for GroupChange messages is now 1.1, changed from 1.0. Also
A GroupChange message is generated when a new user is created to log that the
user has been added to their primary group.
The leading "JSON <message type>:" and source file prefix of the JSON formatted
log entries has been removed to make the parsing of the JSON log messages
easier. JSON log entries now start with 2 spaces followed by an opening brace
i.e. " {"
SMBv2 samba-tool support
------------------------
On previous releases, some samba-tool commands would not work against a remote
DC that had SMBv1 disabled. SMBv2 support has now been added for samba-tool.
The affected commands are 'samba-tool domain backup|rename' and the
'samba-tool gpo' set of commands.
New glusterfs_fuse VFS module
-----------------------------
The new vfs_glusterfs_fuse module improves performance when Samba
accesses a glusterfs volume mounted via FUSE (Filesystem in Userspace
as part of the Linux kernel). It achieves that by leveraging a
mechanism to retrieve the appropriate case of filenames by querying a
specific extended attribute in the filesystem. No extra configuration
is required to use this module, only glusterfs_fuse needs to be set in
the "vfs objects" parameter. Further details can be found in the
vfs_glusterfs_fuse(8) manpage. This new vfs_glusterfs_fuse module does
not replace the existing vfs_glusterfs module, it just provides an
additional, alternative mechanism to access a Gluster volume.
REMOVED FEATURES
================
MIT Kerberos build of the AD DC
-------------------------------
While not removed, the MIT Kerberos build of the Samba AD DC is still
considered experimental. Because Samba will not issue security
patches for this configuration, such builds now require the explicit
configure option: --with-experimental-mit-ad-dc
For further details see
https://wiki.samba.org/index.php/Running_a_Samba_AD_DC_with_MIT_Kerberos_KDC
samba_backup
------------
The samba_backup script has been removed. This has now been replaced by the
'samba-tool domain backup offline' command.
SMB client Python bindings
--------------------------
The SMB client python bindings are now deprecated and will be removed in future
Samba releases. This will only affects users that may have used the Samba
Python bindings to write their own utilities, i.e. users with a custom Python
script that includes the line 'from samba import smb'.

samba4: updated to 4.12.0
samba 4.12.0:
NEW FEATURES/CHANGES
====================
Python 3.5 Required
-------------------
Samba's minimum runtime requirement for python was raised to Python
3.4 with samba 4.11. Samba 4.12 raises this minimum version to Python
3.5 both to access new features and because this is the oldest version
we test with in our CI infrastructure.
(Build time support for the file server with Python 2.6 has not
changed)
Removing in-tree cryptography: GnuTLS 3.4.7 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 3.4.7 to be installed (including development
headers at build time) for all configurations, not just the Samba AD
DC.
Thanks to this work Samba no longer ships an in-tree DES
implementation and on GnuTLS 3.6.5 or later Samba will include no
in-tree cryptography other than the MD4 hash and that
implemented in our copy of Heimdal.
Using GnuTLS for SMB3 encryption you will notice huge performance and copy
speed improvements. Tests with the CIFS Kernel client from Linux Kernel 5.3
show a 3x speed improvement for writing and a 2.5x speed improvement for reads!
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.
zlib library is now required to build Samba
-------------------------------------------
Samba no longer includes a local copy of zlib in our source tarball.
By removing this we do not need to ship (even where we did not
build) the old, broken zip encryption code found there.
New Spotlight backend for Elasticsearch
---------------------------------------
Support for the macOS specific Spotlight search protocol has been enhanced
significantly. Starting with 4.12 Samba supports using Elasticsearch as search
backend. Various new parameters have been added to configure this:
spotlight backend = noindex | elasticsearch | tracker
elasticsearch:address = ADDRESS
elasticsearch:port = PORT
elasticsearch:use tls = BOOLEAN
elasticsearch:index = INDEXNAME
elasticsearch:mappings = PATH
elasticsearch:max results = NUMBER
Samba also ships a Spotlight client command "mdfind" which can be used to search
any SMB server that runs the Spotlight RPC service. See the manpage of mdfind
for details.
Note that when upgrading existing installations that are using the previous
default Spotlight backend Gnome Tracker must explicitly set "spotlight backend =
tracker" as the new default is "noindex".
'net ads kerberos pac save' and 'net eventlog export'
-----------------------------------------------------
The 'net ads kerberos pac save' and 'net eventlog export' tools will
no longer silently overwrite an existing file during data export. If
the filename given exits, an error will be shown.
Fuzzing
-------
A large number of fuzz targets have been added to Samba, and Samba has
been registered in Google's oss-fuzz cloud fuzzing service. In
particular, we now have good fuzzing coverage of our generated NDR
parsing code.
A large number of issues have been found and fixed thanks to this
effort.
'samba-tool' improvements add contacts as member to groups
----------------------------------------------------------
Previously 'samba-tool group addmemers' can just add users, groups and
computers as members to groups. But also contacts can be members of
groups. Samba 4.12 adds the functionality to add contacts to
groups. Since contacts have no sAMAccountName, it's possible that
there are more than one contact with the same name in different
organizational units. Therefore it's necessary to have an option to
handle group members by their DN.
To get the DN of an object there is now the "--full-dn" option available
for all necessary commands.
The MS Windows UI allows to search for specific types of group members
when searching for new members for a group. This feature is included
here with the new samba-tool group addmembers "--object-type=OBJECTYPE"
option. The different types are selected accordingly to the Windows
UI. The default samba-toole behaviour shouldn't be changed.
Allow filtering by OU or subtree in samba-tool
----------------------------------------------
A new "--base-dn" and "--member-base-dn" option is added to relevant
samba-tool user, group and ou management commands to allow operation
on just one part of the AD tree, such as a single OU.
VFS
===
SMB_VFS_NTIMES
--------------
Samba now uses a sentinel value based on utimensat(2) UTIME_OMIT to denote
to-be-ignored timestamp variables passed to the SMB_VFS_NTIMES() VFS function.
VFS modules can check whether any of the time values inside a struct
smb_file_time is to be ignored by calling is_omit_timespec() on the value.
'io_uring' vfs module
---------------------
The module makes use of the new io_uring infrastructure
(intruduced in Linux 5.1), see https://lwn.net/Articles/776703/
Currently this implements SMB_VFS_{PREAD,PWRITE,FSYNC}_SEND/RECV
and avoids the overhead of the userspace threadpool in the default
vfs backend. See also vfs_io_uring(8).
In order to build the module you need the liburing userspace library
and its developement headers installed, see
https://git.kernel.dk/cgit/liburing/
At runtime you'll need a Linux kernel with version 5.1 or higher.
Note that 5.4.14 and 5.4.15 have a regression that breaks the Samba
module! The regression was fixed in Linux 5.4.16 again.
MS-DFS changes in the VFS
-------------------------
This release changes set getting and setting of MS-DFS redirects
on the filesystem to go through two new VFS functions:
SMB_VFS_CREATE_DFS_PATHAT()
SMB_VFS_READ_DFS_PATHAT()
instead of smbd explicitly storing MS-DFS redirects inside
symbolic links on the filesystem. The underlying default
implementations of this has not changed, the redirects are
still stored inside symbolic links on the filesystem, but
moving the creation and reading of these links into the VFS
as first-class functions now allows alternate methods of
storing them (maybe in extended attributes) for OEMs who
don't want to mis-use filesystem symbolic links in this
way.
CTDB changes
============
* The ctdb_mutex_fcntl_helper periodically re-checks the lock file
The re-check period is specified using a 2nd argument to this
helper. The default re-check period is 5s.
If the file no longer exists or the inode number changes then the
helper exits. This triggers an election.
REMOVED FEATURES
================
The smb.conf parameter "write cache size" has been removed.
Since the in-memory write caching code was written, our write path has
changed significantly. In particular we have gained very flexible
support for async I/O, with the new linux io_uring interface in
development. The old write cache concept which cached data in main
memory followed by a blocking pwrite no longer gives any improvement
on modern systems, and may make performance worse on memory-contrained
systems, so this functionality should not be enabled in core smbd
code.
In addition, it complicated the write code, which is a performance
critical code path.
If required for specialist purposes, it can be recreated as a VFS
module.
Retiring DES encryption types in Kerberos.
------------------------------------------
With this release, support for DES encryption types has been removed from
Samba, and setting DES_ONLY flag for an account will cause Kerberos
authentication to fail for that account (see RFC-6649).
Samba-DC: DES keys no longer saved in DB.
-----------------------------------------
When a new password is set for an account, Samba DC will store random keys
in DB instead of DES keys derived from the password. If the account is being
migrated to Windbows or to an older version of Samba in order to use DES keys,
the password must be reset to make it work.
Heimdal-DC: removal of weak-crypto.
-----------------------------------
Following removal of DES encryption types from Samba, the embedded Heimdal
build has been updated to not compile weak crypto code (HEIM_WEAK_CRYPTO).
vfs_netatalk: The netatalk VFS module has been removed.
-------------------------------------------------------
The netatalk VFS module has been removed. It was unmaintained and is not needed
any more.
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 removes the 'rndc command' smb.conf parameter, which
supported this configuration by writing out a list of DCs permitted to
make changes to the DNS Zone and nudging the 'named' server if a new
DC was added to the domain. Administrators using BIND9_FLATFILE will
need to maintain this manually from now on.
