+ Release Notes for Samba 4.15.13
+ December 15, 2022
+ ===============================
-This is the first preview release of Samba 4.12. 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 4.12 will be the next version of the Samba suite.
+This is the latest stable release of the Samba 4.15 release series.
+It also contains security changes in order to address the following defects:
+o CVE-2022-37966: This is the Samba CVE for the Windows Kerberos
+ RC4-HMAC Elevation of Privilege Vulnerability
+ disclosed by Microsoft on Nov 8 2022.
-UPGRADING
-=========
+ A Samba Active Directory DC will issue weak rc4-hmac
+ session keys for use between modern clients and servers
+ despite all modern Kerberos implementations supporting
+ the aes256-cts-hmac-sha1-96 cipher.
+
+ On Samba Active Directory DCs and members
+ 'kerberos encryption types = legacy' would force
+ rc4-hmac as a client even if the server supports
+ aes128-cts-hmac-sha1-96 and/or aes256-cts-hmac-sha1-96.
+
+ https://www.samba.org/samba/security/CVE-2022-37966.html
+
+o CVE-2022-37967: This is the Samba CVE for the Windows
+ Kerberos Elevation of Privilege Vulnerability
+ disclosed by Microsoft on Nov 8 2022.
+
+ A service account with the special constrained
+ delegation permission could forge a more powerful
+ ticket than the one it was presented with.
+
+ https://www.samba.org/samba/security/CVE-2022-37967.html
+
+o CVE-2022-38023: The "RC4" protection of the NetLogon Secure channel uses the
+ same algorithms as rc4-hmac cryptography in Kerberos,
+ and so must also be assumed to be weak.
+
+ https://www.samba.org/samba/security/CVE-2022-38023.html
+
+o CVE-2022-45141: Since the Windows Kerberos RC4-HMAC Elevation of Privilege
+ Vulnerability was disclosed by Microsoft on Nov 8 2022
+ and per RFC8429 it is assumed that rc4-hmac is weak,
+
+ Vulnerable Samba Active Directory DCs will issue rc4-hmac
+ encrypted tickets despite the target server supporting
+ better encryption (eg aes256-cts-hmac-sha1-96).
+
+ https://www.samba.org/samba/security/CVE-2022-45141.html
+
+Note that there are several important behavior changes
+included in this release, which may cause compatibility problems
+interacting with system still expecting the former behavior.
+Please read the advisories of CVE-2022-37966,
+CVE-2022-37967 and CVE-2022-38023 carefully!
+
+samba-tool got a new 'domain trust modify' subcommand
+-----------------------------------------------------
+
+This allows "msDS-SupportedEncryptionTypes" to be changed
+on trustedDomain objects. Even against remote DCs (including Windows)
+using the --local-dc-ipaddress= (and other --local-dc-* options).
+See 'samba-tool domain trust modify --help' for further details.
+

+ Release Notes for Samba 4.15.0
+ September 20, 2021
+ ==============================
+
+
+This is the first stable release of the Samba 4.15 release series.
+Please read the release notes carefully before upgrading.
+
+
+Removed SMB (development) dialects
+==================================
+
+The following SMB (development) dialects are no longer
+supported: SMB2_22, SMB2_24 and SMB3_10. They are were
+only supported by Windows technical preview builds.
+They used to be useful in order to test against the
+latest Windows versions, but it's no longer useful
+to have them. If you have them explicitly specified
+in your smb.conf or an the command line,
+you need to replace them like this:
+- SMB2_22 => SMB3_00
+- SMB2_24 => SMB3_00
+- SMB3_10 => SMB3_11
+Note that it's typically not useful to specify
+"client max protocol" or "server max protocol"
+explicitly to a specific dialect, just leave
+them unspecified or specify the value "default".
+
+New GPG key

+
+New minimum version for the experimental MIT KDC
+================================================
+
+The build of the AD DC using the system MIT Kerberos, an
+experimental feature, now requires MIT Kerberos 1.19. An up-to-date
+Fedora 34 has this version and has backported fixes for the KDC crash
+bugs CVE-2021-37750 and CVE-2021-36222
NEW FEATURES/CHANGES
====================
+VFS
+---
+
+The effort to modernize Samba's VFS interface is complete and Samba 4.15.0 ships
+with a modernized VFS designed for the post SMB1 world.
+
+For details please refer to the documentation at source3/modules/The_New_VFS.txt
+or visit the <https://wiki.samba.org/index.php/The_New_VFS>.
+
+
+Bind DLZ: add the ability to set allow/deny lists for zone transfer clients
+---------------------------------------------------------------------------
+
+Up to now, any client could use a DNS zone transfer request to the
+bind server, and get an answer from Samba. Now the default behaviour
+will be to deny those request. Two new options have been added to
+manage the list of authorized/denied clients for zone transfer
+requests. In order to be accepted, the request must be issued by a
+client that is in the allow list and NOT in the deny list.
+
+
+"server multi channel support" no longer experimental
+-----------------------------------------------------
+
+This option is enabled by default starting with 4.15 (on Linux and FreeBSD).
+Due to dependencies on kernel APIs of Linux or FreeBSD, it's only possible
+to use this feature on Linux and FreeBSD for now.
+
+
+samba-tool available without the ad-dc
+--------------------------------------
+
+The 'samba-tool' command is now available when samba is configured
+"--without-ad-dc". Not all features will work, and some ad-dc specific options
+have been disabled. The 'samba-tool domain' options, for example, are limited
+when no ad-dc is present. Samba must still be built with ads in order to enable
+'samba-tool'.
+
+
+Improved command line user experience
+-------------------------------------
+
+Samba utilities did not consistently implement their command line interface. A
+number of options were requiring to specify values in one tool and not in the
+other, some options meant different in different tools.
+
+These should be stories of the past now. A new command line parser has been
+implemented with sanity checking. Also the command line interface has been
+simplified and provides better control for encryption, signing and kerberos.
+
+Previously many tools silently ignored unknown options. To prevent unexpected
+behaviour all tools will now consistently reject unknown options.
+
+Also several command line options have a smb.conf variable to control the
+default now.
+
+All tools are now logging to stderr by default. You can use "--debug-stdout" to
+change the behavior. All servers will log to stderr at early startup until logging
+is setup to go to a file by default.
+
+### Common parser:
+
+Options added:
+--client-protection=off|sign|encrypt
+
+Options renamed:
+--kerberos -> --use-kerberos=required|desired|off
+--krb5-ccache -> --use-krb5-ccache=CCACHE
+--scope -> --netbios-scope=SCOPE
+--use-ccache -> --use-winbind-ccache
+
+Options removed:
+-e|--encrypt
+-C removed from --use-winbind-ccache
+-i removed from --netbios-scope
+-S|--signing
+
+
+### Duplicates in command line utils
+
+ldbadd/ldbdel/ldbedit/ldbmodify/ldbrename/ldbsearch:
+-e is still available as an alias for --editor,
+ as it used to be.
+-s is no longer reported as an alias for --configfile,
+ it never worked that way as it was shadowed by '-s' for '--scope'.
+
+ndrdump:
+-l is not available for --load-dso anymore
+
+net:
+-l is not available for --long anymore
+
+sharesec:
+-V is not available for --viewsddl anymore
+
+smbcquotas:
+--user -> --quota-user
+
+nmbd:
+--log-stdout -> --debug-stdout
+
+smbd:
+--log-stdout -> --debug-stdout
+
+winbindd:
+--log-stdout -> --debug-stdout
+
+
+Scanning of trusted domains and enterprise principals
+-----------------------------------------------------
+
+As an artifact from the NT4 times, we still scanned the list of trusted domains
+on winbindd startup. This is wrong as we never can get a full picture in Active
+Directory. It is time to change the default value to "No". Also with this change
+we always use enterprise principals for Kerberos so that the DC will be able
+to redirect ticket requests to the right DC. This is e.g. needed for one way
+trusts. The options `winbind use krb5 enterprise principals` and
+`winbind scan trusted domains` will be deprecated in one of the next releases.
+
+
+Support for Offline Domain Join (ODJ)
+-------------------------------------
+
+The net utility is now able to support the offline domain join feature
+as known from the Windows djoin.exe command for many years. Samba's
+implementation is accessible via the 'net offlinejoin' subcommand. It
+can provision computers and request offline joining for both Windows
+and Unix machines. It is also possible to provision computers from
+Windows (using djoin.exe) and use the generated data in Samba's 'net'
+utility. The existing options for the provisioning and joining steps
+are documented in the net(8) manpage.
+
+
+'samba-tool dns zoneoptions' for aging control
+----------------------------------------------
+
+The 'samba-tool dns zoneoptions' command can be used to turn aging on
+and off, alter the refresh and no-refresh periods, and manipulate the
+timestamps of existing records.
+
+To turn aging on for a zone, you can use something like this:
+
+ samba-tool dns zoneoptions --aging=1 --refreshinterval=306600
+
+which turns on aging and ensures no records less than five years old
+are aged out and scavenged. After aging has been on for sufficient
+time for records to be renewed, the command
+
+ samba-tool dns zoneoptions --refreshinterval=168
+
+will set the refresh period to the standard seven days. Using this two
+step process will help prevent the temporary loss of dynamic records
+if scavenging happens before their first renewal.
+
+
+Marking old records as static or dynamic with 'samba-tool'
+----------------------------------------------------------
+
+A bug in Samba versions prior to 4.9 meant records that were meant to
+be static were marked as dynamic and vice versa. To fix the timestamps
+in these domains, it is possible to use the following options,
+preferably before turning aging on.
+
+ --mark-old-records-static
+ --mark-records-dynamic-regex
+ --mark-records-static-regex
+
+The "--mark-old-records-static" option will make records older than the
+specified date static (that is, with a zero timestamp). For example,
+if you upgraded to Samba 4.9 in November 2018, you could use ensure no
+old records will be mistakenly interpreted as dynamic using the
+following option:
+
+ samba-tool dns zoneoptions --mark-old-records-static=2018-11-30
+
+Then, if you know that that will have marked some records as static
+that should be dynamic, and you know which those are due to your
+naming scheme, you can use commands like:
+
+ samba-tool dns zoneoptions --mark-records-dynamic-regex='\w+-desktop'
+
+where '\w+-desktop' is a perl-compatible regular expression that will
+match 'bob-desktop', 'alice-desktop', and so on.
+
+These options are deliberately long and cumbersome to type, so people
+have a chance to think before they get to the end. You can make a
+mess if you get it wrong.
+
+All 'samba-tool dns zoneoptions' modes can be given a "--dry-run/-n"
+argument that allows you to inspect the likely results before going
+ahead.
+
+NOTE: for aging to work, you need to have "dns zone scavenging = yes"
+set in the smb.conf of at least one server.
+
+
+DNS tombstones are now deleted as appropriate
+---------------------------------------------
+
+When all the records for a DNS name have been deleted, the node is put
+in a tombstoned state (separate from general AD object tombstoning,
+which deleted nodes also go through). These tombstones should be
+cleaned up periodically. Due to a conflation of scavenging and
+tombstoning, we have only been deleting tombstones when aging is
+enabled.
+
+If you have a lot of tombstoned DNS nodes (that is, DNS names for
+which you have removed all the records), cleaning up these DNS
+tombstones may take a noticeable time.
+
+
+DNS tombstones use a consistent timestamp format
+------------------------------------------------
+
+DNS records use an hours-since-1601 timestamp format except for in the
+case of tombstone records where a 100-nanosecond-intervals-since-1601
+format is used (this latter format being the most common in Windows).
+We had mixed that up, which might have had strange effects in zones
+where aging was enabled (and hence tombstone timestamps were used).
+
+
+samba-tool dns update and RPC changes
+-------------------------------------
+
+The dnsserver DCERPC pipe can be used by 'samba-tool' and Windows tools
+to manipulate dns records on the remote server. A bug in Samba meant
+it was not possible to update an existing DNS record to change the
+TTL. The general behaviour of RPC updates is now closer to that of
+Windows.
+
+'samba-tool dns update' is now a bit more careful in rejecting and
+warning you about malformed IPv4 and IPv6 addresses.
+
+CVE-2021-3671: Crash in Heimdal KDC and updated security release policy
+-----------------------------------------------------------------------
+
+An unuthenticated user can crash the AD DC KDC by omitting the server
+name in a TGS-REQ. Per Samba's updated security process a specific
+security release was not made for this issue as it is a recoverable
+Denial Of Service.
+
+See https://wiki.samba.org/index.php/Samba_Security_Proces
+
+samba-tool domain backup offline with the LMDB backend
+------------------------------------------------------
+
+samba-tool domain backup offline, when operating with the LMDB backend
+now correctly takes out locks against concurrent modification of the
+database during the backup. If you use this tool on a Samba AD DC
+using LMDB, you should upgrade to this release for safer backups.
