707 Release Notes for Samba 4.14.4
709 ==============================
712 This is a security release in order to address the following defect:
714 o CVE-2021-20254: Negative idmap cache entries can cause incorrect group entries
715 in the Samba file server process token.
723 The Samba smbd file server must map Windows group identities (SIDs) into unix
724 group ids (gids). The code that performs this had a flaw that could allow it
725 to read data beyond the end of the array in the case where a negative cache
726 entry had been added to the mapping cache. This could cause the calling code
727 to return those values into the process token that stores the group
728 membership for a user.
730 Most commonly this flaw caused the calling code to crash, but an alert user
731 (Peter Eriksson, IT Department, Linköping University) found this flaw by
732 noticing an unprivileged user was able to delete a file within a network
733 share that they should have been disallowed access to.
735 Analysis of the code paths has not allowed us to discover a way for a
736 remote user to be able to trigger this flaw reproducibly or on demand,
737 but this CVE has been issued out of an abundance of caution.
743 o Volker Lendecke <vl@samba.org>
744 * BUG 14571: CVE-2021-20254: Fix buffer overrun in sids_to_unixids().

1000 Here is a copy of a clarification note added to the Samba code
1001 in the file: VFS-License-clarification.txt.
1002 --------------------------------------------------------------
1004 A clarification of our GNU GPL License enforcement boundary within the Samba
1005 Virtual File System (VFS) layer.
1007 Samba is licensed under the GNU GPL. All code committed to the Samba
1008 project or that creates a "modified version" or software "based on" Samba must
1009 be either licensed under the GNU GPL or a compatible license.
1011 Samba has several plug-in interfaces where external code may be called
1012 from Samba GNU GPL licensed code. The most important of these is the
1015 Samba VFS modules are intimately connected by header files and API
1016 definitions to the part of the Samba code that provides file services,
1017 and as such, code that implements a plug-in Samba VFS module must be
1018 licensed under the GNU GPL or a compatible license.
1020 However, Samba VFS modules may themselves call third-party external
1021 libraries that are not part of the Samba project and are externally
1022 developed and maintained.
1024 As long as these third-party external libraries do not use any of the
1025 Samba internal structure, APIs or interface definitions created by the
1026 Samba project (to the extent that they would be considered subject to the GNU
1027 GPL), then the Samba Team will not consider such third-party external
1028 libraries called from Samba VFS modules as "based on" and/or creating a
1029 "modified version" of the Samba code for the purposes of GNU GPL.
1030 Accordingly, we do not require such libraries be licensed under the GNU GPL
1031 or a GNU GPL compatible license.
1036 The effort to modernize Samba's VFS interface has reached a major milestone with
1037 the next release Samba 4.14.
1039 For details please refer to the documentation at source3/modules/The_New_VFS.txt or
1040 visit the <https://wiki.samba.org/index.php/The_New_VFS>.
1045 Publishing printers in AD is more reliable and more printer features are
1046 added to the published information in AD. Samba now also supports Windows
1047 drivers for the ARM64 architecture.
1051 This release extends Samba to support Group Policy functionality for Winbind
1052 clients. Active Directory Administrators can set policies that apply Sudoers
1053 configuration, and cron jobs to run hourly, daily, weekly or monthly.
1055 To enable the application of Group Policies on a client, set the global
1056 smb.conf option 'apply group policies' to 'yes'. Policies are applied on an
1057 interval of every 90 minutes, plus a random offset between 0 and 30 minutes.
1059 Policies applied by Samba are 'non-tattooing', meaning that changes can be
1060 reverted by executing the `samba-gpupdate --unapply` command. Policies can be
1061 re-applied using the `samba-gpupdate --force` command.
1062 To view what policies have been or will be applied to a system, use the
1063 `samba-gpupdate --rsop` command.
1065 Administration of Samba policy requires that a Samba ADMX template be uploaded
1066 to the SYSVOL share. The samba-tool command `samba-tool gpo admxload` is
1067 provided as a convenient method for adding this policy. Once uploaded, policies
1068 can be modified in the Group Policy Management Editor under Computer
1069 Configuration/Policies/Administrative Templates. Alternatively, Samba policy
1070 may be managed using the `samba-tool gpo manage` command. This tool does not
1071 require the admx templates to be installed.
1073 Python 3.6 or later required
1074 ----------------------------
1076 Samba's minimum runtime requirement for python was raised to Python
1077 3.6 with samba 4.13. Samba 4.14 raises this minimum version to Python
1078 3.6 also to build Samba. It is no longer possible to build Samba
1079 (even just the file server) with Python versions 2.6 and 2.7.
1081 As Python 2.7 has been End Of Life upstream since April 2020, Samba
1082 is dropping ALL Python 2.x support in this release.
1084 Miscellaneous samba-tool changes
1085 --------------------------------
1087 The 'samba-tool' subcommands to manage AD objects (e.g. users, computers and
1088 groups) now consistently use the "add" command when adding a new object to
1089 the AD. The previous deprecation warnings when using the 'add' commands
1090 have been removed. For compatibility reasons, both the 'add' and 'create'
1091 commands can be used now.
1093 Users, groups and contacts can now be renamed with the respective rename
1096 Locked users can be unlocked with the new 'samba-tool user unlock' command.
1098 The 'samba-tool user list' and 'samba-tool group listmembers' commands
1099 provide additional options to hide expired and disabled user accounts
1100 (--hide-expired and --hide-disabled).
1106 * The NAT gateway and LVS features now uses the term "leader" to refer
1107 to the main node in a group through which traffic is routed and
1108 "follower" for other members of a group. The command for
1109 determining the leader has changed to "ctdb natgw leader" (from
1110 "ctdb natgw master"). The configuration keyword for indicating that
1111 a node can not be the leader of a group has changed to
1112 "follower-only" (from "slave-only"). Identical changes were made
1115 * Remove "ctdb isnotrecmaster" command. It isn't used by CTDB's
1116 scripts and can be checked by users with "ctdb pnn" and "ctdb
