Samba 4.10.8

Release Notes for Samba 4.10.8
September 03, 2019

This is a security release in order to address the following defect:

  • CVE-2019-10197: Combination of parameters and permissions can allow user to escape from the share path definition.

Details

Under certain parameter configurations, when an SMB client accesses a network share and the user does not have permission to access the share root directory, it is possible for the user to escape from the share to see the complete '/' filesystem. Unix permission checks in the kernel are still enforced.

Samba 4.10.0

Release Notes for Samba 4.10.0
March 19, 2019

Release Announcements

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 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: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.

Note: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. Refer also BUG #13676.

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 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'.
