Release Announcements ===================== This is the second release candidate of Samba 4.15. 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 4.15 will be the next version of the Samba suite. 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 ----------- The GPG release key for Samba releases changed from: pub dsa1024/6F33915B6568B7EA 2007-02-04 [SC] [expires: 2021-02-05] Key fingerprint = 52FB C0B8 6D95 4B08 4332 4CDC 6F33 915B 6568 B7EA uid [ full ] Samba Distribution Verification Key <samba-b...@samba.org> sub elg2048/9C6ED163DA6DFB44 2007-02-04 [E] [expires: 2021-02-05] to the following new key: pub rsa4096/AA99442FB680B620 2020-12-21 [SC] [expires: 2022-12-21] Key fingerprint = 81F5 E283 2BD2 545A 1897 B713 AA99 442F B680 B620 uid [ultimate] Samba Distribution Verification Key <samba-b...@samba.org> sub rsa4096/97EF9386FBFD4002 2020-12-21 [E] [expires: 2022-12-21] Starting from Jan 21th 2021, all Samba releases will be signed with the new key. See also GPG_AA99442FB680B620_replaces_6F33915B6568B7EA.txt NEW FEATURES/CHANGES ==================== - bind DLZ: Added 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 to 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, singing and kerberos. Also several command line options have a smb.conf variable to control the default now. All tools are logging to stderr by default. You can use --debug-stdout to change the behavior. ### 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/ldbsearch/ldbdel/ldbmodify/ldbrename: -e is not available for --editor anymore -s is not used for --configfile anymore 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. REMOVED FEATURES ================ Tru64 ACL support has been removed from this release. The last supported release of Tru64 UNIX was in 2012. NIS support has been removed from this release. This is not available in Linux distributions anymore. The DLZ DNS plugin is no longer built for Bind versions 9.8 and 9.9, which have been out of support since 2018. smb.conf changes ================ Parameter Name Description Default -------------- ----------- ------- client use kerberos New desired client max protocol Values Removed client min protocol Values Removed client protection New default client smb3 signing algorithms New see man smb.conf client smb3 encryption algorithms New see man smb.conf preopen:posix-basic-regex New No preopen:nomatch_log_level New 5 preopen:match_log_level New 5 preopen:nodigits_log_level New 1 preopen:founddigits_log_level New 3 preopen:reset_log_level New 5 preopen:push_log_level New 3 preopen:queue_log_level New 10 server max protocol Values Removed server min protocol Values Removed server multi channel support Changed Yes (on Linux and FreeBSD) server smb3 signing algorithms New see man smb.conf server smb3 encryption algorithms New see man smb.conf winbind use krb5 enterprise principals Changed Yes winbind scan trusted domains Changed No CHANGES SINCE 4.15.0rc1 ======================= o Andreas Schneider <a...@samba.org> * BUG 14768: smbd/winbind should load the registry if configured * BUG 14777: do not quote passed argument of configure script * BUG 14779: Winbind should not start if the socket path is too long o Stefan Metzmacher <me...@samba.org> * BUG 14607: tree connect failed: NT_STATUS_INVALID_PARAMETER * BUG 14764: aes-256-gcm and aes-256-ccm doesn't work in the server o Ralph Boehme <s...@samba.org> * BUG 14700: file owner not available when file unredable o Jeremy Allison <j...@samba.org> * BUG 14607: tree connect failed: NT_STATUS_INVALID_PARAMETER * BUG 14759: 4.15rc can leak meta-data about the directory containing the share path KNOWN ISSUES ============ https://wiki.samba.org/index.php/Release_Planning_for_Samba_4.15#Release_blocking_bugs ####################################### Reporting bugs & Development Discussion ####################################### Please discuss this release on the samba-technical mailing list or by joining the #samba-technical IRC channel on irc.freenode.net.
