424 -----------------------------------------------------------------------------
425 The release notes for 2.2.3a follow :
427 This is a minor bugfix release for the 2.2.3 release. The 2.2.3
428 release had a problem that was visible to Windows 2000 Explorer
429 users in that copying files into a share that already existed
430 failed with "Access Denied" rather than asking the user if an
431 overwrite was required. This was due to an incorrect error mapping
432 between the UNIX EXIST error code and the NT status error.
434 As Windows Explorer is a highly visible end user application a quick
435 bugfix release was required, hence 2.2.3a.
437 Compilation on HPUX versions earlier than HPUX 11 has also been
440 The cvs.log file is no longer included with this release, as it adds
441 13Mb to the size of the release, and is easily available on the Web.
443 -----------------------------------------------------------------------------
444 The release notes for 2.2.3 follow :
446 There are several important scaling bugs that have been fixed in this release
447 for large server systems so an upgrade is recommended.
452 Much work has been done on the LDAP backend code. The configure
453 option --with-ldapsam is now considered to be stable. The schema
454 used has changed, see the file examples/LDAP/samba.schema for the
457 New documentation explaining how to set up a Samba only PDC/BDC
458 setup has been added in the files Samba-LDAP-HOWTO and Samba-BDC-HOWTO
459 in the documentation tree.
461 winbindd daemon extended
462 ------------------------
464 Samba 2.2.2 was the first release to include the winbind daemon.
465 This code allows UNIX systems that implement the name service
466 switch (nss) to be entered into a Windows NT/2000 domain and
467 use the Domain controller for all user and group enumeration.
469 Samba 2.2.3 fixes the known memory leaks in winbindd and has
470 been extended to work with SGI IRIX and HPUX (11.x) in addition
471 to the earlier targets of Linux and Solaris.
473 For more information on using winbind, see the man pages for
476 Note that winbindd is not installed by default.
478 New/Changed parameters in 2.2.3
479 --------------------------------
481 For more information on these parameters, see the man pages for
484 Added/changed parameters.
485 -------------------------
489 Enables the experimental UNIX CIFS extensions in smbd. See the manpage
494 Some printer drivers will crash the Windows NT/2000 spooler service
495 if they are given a default devmode, some require it. This parameter
496 allows the administrator a choice of whether smbd returns such a
497 default devmode for a driver.
501 This parameter has been restored to allow people who wish smbd to ignore
502 client share modes. This is *very dangerous* and should not be set without
503 full knowledge of what this is designed for.
508 1). Fixed shared library compile for Solaris with native compiler.
509 2). UNIX CIFS extensions code added (donated by HP).
510 3). Changed to using NT status codes on the wire if the client can support
512 4). altname command to show 8.3 name added to smbclient.
513 5). const-safe endian macros now used.
514 6). client code now uses UNICODE on the wire.
515 7). Correctly return fault PDU's on bad handle.
516 8). Improved NT error code mapping table.
517 9). Many new point and print RPC calls added.
518 10). Win9x clients can now see full user list.
519 11). field added to identify simultaneous open files (no longer
520 use dev/inode/time as unique value).
521 12). HPUX ACL code added (donated by HP).
522 13). vfs interfaces updated (again !).
523 14). MSDOS Code Page 866 -> 1251 mapping added.
524 15). winbindd now processes quit/hup signals correctly.
525 16). No tdb traversal done on startup/shutdown - ensures scalability.
526 17). Fix bug with paths for homes share.
527 18). Fixed copyfile for OS/2.
528 19). Fix group membership when groups are on more than one line.
529 20). Fixed core dumps in posix ACL mapping code.
530 21). Tidyup of UNICODE functions (put/get).
531 22). Move rpcclient to the new libsmb code.
532 23). Add missing Windows 2000 passthough trans2 calls.
533 24). Return check all tdb calls.
534 25). Make local name lookup work even if wins server is down.
535 26). pam session code added to winbind.
536 27). Added winbindd cache to all lookups.
537 28). Fix allocate bugs that caused file sizes to be incorrect.
538 29). Fixed write cache code - now safe to use.
539 30). Fixed winbindd memory leaks.
540 31). winbindd will now do name lookups (to allow non Open Source
541 systems to do the nsswitch WINS lookup). Fixed by SGI.
542 32). passdb memory leaks fixed.
543 33). LDAP code updates and now properly maintained.
544 34). Finally figured out how changeid is meant to work.
545 35). Downlevel printing now looks as NT does in print monitor window.
546 36). Many fixups in spoolss printing RPC parsing.
547 37). Speed up password enumeration as a PDC.
548 38). Fix printer changed notify messages (work from HP).
549 39). Fix modify timestamp on close code.
550 40). Fix long standing mangled names bug.
551 41). Fix delete on close semantics.
552 42). Stop opening all files with O_NONBLOCK !
553 43). Use O_NOFOLLOW for systems that have it and don't want symlinks.
554 44). Ensure NT supplementary groups get added to user token.
555 45). Try and mitigate effects of DNS timeout (do less lookups).
556 46). Added current user connection context stack.
557 47). Fixes to utmp code.
558 48). smbw code tidyups.
559 49). Added tdb open log code. Several tdb fixes.
561 -----------------------------------------------------------------------------
562 The release notes for 2.2.2 follow :
564 New daemon included - winbindd
565 ------------------------------
567 Samba 2.2.2 is the first release to include the winbind daemon.
568 This code allows UNIX systems that implement the name service
569 switch (nss) to be entered into a Windows NT/2000 domain and
570 use the Domain controller for all user and group enumeration.
572 This allows a Samba server added to a Windows domain to serve
573 file and print services with *NO* local users needed in /etc/passwd
574 and /etc/group - all users and groups are read directly from the
575 Windows domain controller. In addition with pam_winbind which allows
576 a PAM enabled UNIX system to use a Windows domain for authentication
577 service this allows single sign on and account control across
578 UNIX and Windows systems.
580 The current version of winbindd shipped in 2.2.2 does have some
581 memory leaks, which will be addressed for the next Samba release,
582 so it is advisable to monitor the winbind process. This code is
583 being used in production by several vendors, so the leaks are
584 manageable. In addition, this version of winbind does not work
585 correctly against a Samba PDC, due to some missing calls on the
586 PDC side. These problems are being addressed for the next Samba
587 release, but it was thought better to release the code now rather
588 than delay the main Samba code to match the winbind release schedule.
590 For more information on using winbind, see the man pages for
593 Note that winbindd is not installed by default.
595 New/Changed parameters in 2.2.2
596 -------------------------------
598 For more information on these parameters, see the man pages for
601 Added/changed parameters.
602 -------------------------
606 Causes Samba not to create UNIX 'sparse' files, but to follow the
607 Windows behavior of always allocating on-disk space.
611 Set to 'on' by default, only set to 'off' on HPUX 11.x or below or other
612 UNIX systems that don't have coherent mmap/read-write internal caches.
613 You should not need to set this parameter.
617 This parameter has been changed to a per-share option, and is very
618 useful in enabling Windows 2000 SP2 to load/save profiles from a
621 New printing parameters.
622 ------------------------
626 Setting this parameter causes Samba to go back to the old 2.0.x
627 LANMAN printing behavior, for people who wish to disable the
632 Causes Windows NT/2000 clients to need have a local printer driver
633 installed and to treat the printer as local.
638 Samba 2.2.2 contains new code to maintain a Samba SAM database
639 on a remote LDAP server. These parameters have been added as
640 part of this code. These parameters are only available when Samba
641 has been compiled with the --with-ldapsam option.
649 The SSL support in Samba has been fixed. These new parameters
650 are part of the changes added. These parameters are only available
651 when Samba has been compiled with the --with-ssl option.
652 Please see the smb.conf man page for details.
658 New winbindd parameters.
659 ------------------------
661 These parameters are used by winbindd. See the man page for
662 winbindd for details.
683 Some new README's have been added in the docs/ directory. These cover
684 using roving profiles with Windows 2000 SP2 (docs/README.Win2kSP2),
685 and how to use Samba to help prevent Windows virus spread
686 (docs/README.Win32-Viruses).
688 Quota problems on a Linux 2.4 kernel.
689 -------------------------------------
691 Currently the quota interfaces have diverged between the Linus
692 2.4.x kernels and the Alan Cox 2.4.x kernels (the Alan Cox variants
693 are shipped with RedHat). Running quota-enabled Samba compiled on
694 an Alan Cox kernel works correctly on an Alan Cox kernel (the one
695 shipped by default with RedHat 7.x) but fails on a Linus kernel.
697 This is a mess, and hopefully Alan and Linus will sort it out soon.
698 In the meantime we need to ship.....
703 1). mmap tdb code disabled on HPUX. This should prevent the reports of
704 tdb corruption on HUPX.
705 2). Large file support set to off in Solaris 5.5 and below.
706 3). Better CUPS detection.
707 4). New SAM (password database) backends - smbpasswd (traditional),
708 LDAP, NIS+ and Samba TDB.
709 5). Quota fixups on Linux.
710 6). libsmbclient stand-alone code added. Can be built as a shared library
712 7). Tru64 ACL support added.

718 12). Profile shared memory support added to nmbd.
719 13). New Windows 2000/NT passthrough info levels added.
720 14). readraw/writeraw code rewritten - many bugs fixed.

722 16). Reverse DNS lookup avoided on socket open.
723 17). Bug preventing nmbd re-registering names on WINS server timeout fixed.
724 18). Zero length byte range lock code added. Much closer to Windows semantics.
725 19). Alignment fault fixes for Linux/Alpha.
726 20). Error checking on tdb returns vastly improved.
727 21). Handling of delete on close fixed. No longer possible to leave 'dead'
729 22). Handling of oplock break failure cleanups improved. Should not be
730 able to leave 'dead' entries.
731 23). Fix handling of errors trying to set 64 bit locks on 32 bit NFS mounts.
732 24). Misc. MS-DFS code fixes.
733 25). Ignore logon packets if not a PDC (needed for PDC/BDC failover).
734 26). winbind pam module added.

744 34). Fix for NT sending multiple SetPrinterDataEx calls.
745 35). Fix for logic bug where smbd could delay oplock break request messages
746 from other smbd daemons whilst client kept us busy.
747 36). Fix deadlock problem with connections tdb on enumeration.
748 37). Fixes for setting/getting NT ACLs - improved POSIX mapping both ways.
749 38). Removed unused readbmpx/writebmpx code.
750 39). Attempt to fix Linux 2.4.x quota mess.
751 40). Improved ctemp code for Windows 2000 compatibility.
752 41). Finally understood difference between set EOF and set allocation requests.
753 Added strict allocate parameter to help.
754 42). Correctly return name types on name to SID lookups.
755 43). tdb spinlock code update.
756 44). Use pread/pwrite on systems that have it to fix race condition in tdb code.
758 -----------------------------------------------------------------------------
759 The release notes for 2.2.1a follow :
761 This is a minor bugfix release for 2.2.1, *NOT* security related.
763 1). 2.2.1 had a bug where using smbpasswd -m to add a Windows NT or
764 Windows2000 machine into a Samba hosted PDC would fail due to our
765 stricter user name checking. We were disallowing user names
766 containing '$', which is needed when using smbpasswd to add a
767 machine into a domain. Automatically adding machines (using the
768 native Windows tools) into a Samba domain worked correctly.
770 2.2.1a fixes this single problem.
772 -----------------------------------------------------------------------------
773 The release notes for 2.2.1 follow :
775 New/Changed parameters in 2.2.1
776 -------------------------------
781 obey pam restrictions
783 When Samba is configured to use PAM, turns on or off Samba checking
784 the PAM account restrictions. Defaults to off.
788 When Samba is configured to use PAM, turns on or off Samba passing
789 the password changes to PAM. Defaults to off.
793 New option to allow new Windows 2000 large file (64k) streaming
794 read/write options. Needs a 64 bit underlying operating system
795 (for Linux use kernel 2.4 with glibc 2.2 or above). Can improve performance
796 by 10% with Windows 2000 clients. Defaults to off. Not as tested
797 as some other Samba code paths.
801 Prevents clients from seeing the existence of files that cannot
802 be read. Off by default.
806 Turn on/off the enhanced Samba browsing functionality (*1B names).
807 Default is "on". Can prevent eternal machines in workgroups when
808 WINS servers are not synchronized.
820 1). "find" command removed for smbclient. Internal code now used.
821 2). smbspool updates to retry connections from Michael Sweet.
822 3). Fix for mapping 8859-15 characters to UNICODE.
823 4). Changed "security=server" to try with invalid username to prevent
825 5). Fixes to allow Windows 2000 SP2 clients to join a Samba PDC.
826 6). Support for Windows 9x Nexus tools to allow security changes from Win9x.
827 7). Two locking fixes added. Samba 2.2.1 now passes the Clarion network
828 lock tester tool for distributed databases.
829 8). Preliminary support added for Windows 2000 large file read/write SMBs.
830 9). Changed random number generator in Samba to prevent guess attacks.
831 10). Fixes for tdb corruption in connections.tdb and file locking brlock.tdb.
832 smbd's clean the tdb files on startup and shutdown.
833 11). Fixes for default ACLs on Solaris.
834 12). Tidyup of password entry caching code.
835 13). Correct shutdowns added for send fails. Helps tdb cleanup code.
836 14). Prevent invalid '/' characters in workgroup names.
837 15). Removed more static arrays in SAMR code.
838 16). Client code is now UNICODE on the wire.
839 17). Fix 2 second timestamp resolution everywhere if dos timestamp set to yes.
840 18). All tdb opens now going through logging function.
841 19). Add pam password changing and pam restrictions code.
842 20). Printer driver management improvements (delete driver).
843 21). Fix difference between NULL security descriptors and empty
844 security descriptors.
845 22). Fix SID returns for server roles.
846 23). Allow Windows 2000 mmc to view and set Samba share security descriptors.
847 24). Allow smbcontrol to forcibly disconnect a share.
848 25). tdb fixes for HPUX, OpenBSD and other OS's that don't have a coherent
849 mmap/file read/write cache.
850 26). Fix race condition in returning create disposition for file create/open.
851 27). Fix NT rewriting of security descriptors to their canonical form for
853 28). Fix for Samba running on top of Linux VFAT ftruncate bug.
854 29). Swat fixes for being run with xinetd that doesn't set the umask.
855 30). Fix for slow writes with Win9x Explorer clients. Emulates Microsoft
856 TCP stack early ack specification error.
857 31). Changed lock & persistent tdb directory to /var/cache/samba by default on
858 RedHat and Mandrake as they clear the /var/lock/samba directory on reboot.
860 -----------------------------------------------------------------------------
861 The release notes for 2.2.0a follow :
866 This is a security bugfix release for Samba 2.2.0. This release provides the
867 following two changes *ONLY* from the 2.2.0 release.
869 1). Fix for the security hole discovered by Michal Zalewski (lcamtuf@bos.bindview.com)
870 and described in the security advisory below.
871 2). Fix for the hosts allow/hosts deny parameters not being honoured.
873 No other changes are being made for this release to ensure a security fix only.
874 For new functionality (including these security fixes) download Samba 2.2.1
875 when it is available.
877 The security advisory follows :
880 IMPORTANT: Security bugfix for Samba
881 ------------------------------------
889 A serious security hole has been discovered in all versions of Samba
890 that allows an attacker to gain root access on the target machine for
891 certain types of common Samba configuration.
893 The immediate fix is to edit your smb.conf configuration file and
894 remove all occurances of the macro "%m". Replacing occurances of %m
895 with %I is probably the best solution for most sites.
900 A remote attacker can use a netbios name containing unix path
901 characters which will then be substituted into the %m macro wherever
902 it occurs in smb.conf. This can be used to cause Samba to create a log
903 file on top of an important system file, which in turn can be used to
904 compromise security on the server.
906 The most commonly used configuration option that can be vulnerable to
907 this attack is the "log file" option. The default value for this
908 option is VARDIR/log.smbd. If the default is used then Samba is not
909 vulnerable to this attack.
911 The security hole occurs when a log file option like the following is
914 log file = /var/log/samba/%m.log
916 In that case the attacker can use a locally created symbolic link to
917 overwrite any file on the system. This requires local access to the
920 If your Samba configuration has something like the following:
922 log file = /var/log/samba/%m
924 Then the attacker could successfully compromise your server remotely
925 as no symbolic link is required. This type of configuration is very
928 The most commonly used log file configuration containing %m is the
929 distributed in the sample configuration file that comes with Samba:
931 log file = /var/log/samba/log.%m
933 in that case your machine is not vulnerable to this attack unless you
934 happen to have a subdirectory in /var/log/samba/ which starts with the
940 Thanks to Michal Zalewski (lcamtuf@bos.bindview.com) for finding this
947 While we recommend that vulnerable sites immediately change their
948 smb.conf configuration file to prevent the attack we will also be
949 making new releases of Samba within the next 24 hours to properly fix
950 the problem. Please see http://www.samba.org/ for the new releases.
952 Please report any attacks to the appropriate authority.
957 ---------------------------------------------------------------------------
959 The release notes for 2.2.0 follow :
961 This is the official Samba 2.2.0 release. This version of Samba provides
962 the following new features and enhancements.
964 Integration between Windows oplocks and NFS file opens (IRIX and Linux
965 2.4 kernel only). This gives complete data and locking integrity between
966 Windows and UNIX file access to the same data files.
968 Ability to act as an authentication source for Windows 2000 clients as
969 well as for NT4.x clients.
971 Integration with the winbind daemon that provides a single
972 sign on facility for UNIX servers in Windows 2000/NT4 networks
973 driven by a Windows 2000/NT4 PDC. winbind is not included in
974 this release, it currently must be obtained separately. We are
975 committed to including winbind in a future Samba 2.2.x release.
977 Support for native Windows 2000/NT4 printing RPCs. This includes
978 support for automatic printer driver download.
980 Support for server supported Access Control Lists (ACLs).
981 This release contains support for the following filesystems:
985 Linux Kernel with ACL patch from http://acl.bestbits.at
986 Linux Kernel with XFS ACL support.
989 FreeBSD (with external patch)
991 Other platforms will be supported as resources are
992 available to test and implement the necessary modules. If
993 you are interested in writing the support for a particular
994 ACL filesystem, please join the samba-technical mailing
995 list and coordinate your efforts.
997 On PAM (Pluggable Authentication Module) based systems - better debugging
998 messages and encrypted password users now have access control verified via
999 PAM - Note: Authentication still uses the encrypted password database.
1001 Rewritten internal locking semantics for more robustness.
1002 This release supports full 64 bit locking semantics on all
1003 (even 32 bit) platforms. SMB locks are mapped onto POSIX
1004 locks (32 bit or 64 bit) as the underlying system allows.
1006 Conversion of various internal flat data structures to use
1007 database records for increased performance and
1010 Support for acting as a MS-DFS (Distributed File System) server.
1012 Support for manipulating Samba shares using Windows client tools
1013 (server manager). Per share security can be set using these tools
1014 and Samba will obey the access restrictions applied.
1016 Samba profiling support (see below).
1018 Compile time option for enabling a (Virtual file system) VFS layer
1019 to allow non-disk resources to be exported as Windows filesystems
1020 (such as databases etc.).
1022 The documentation in this release has been updated and converted
1023 from Yodl to DocBook 4.1. There are many new parameters since 2.0.7
1024 and some defaults have changed.
1028 Support for collection of profile information. A shared
1029 memory area has been created which contains counters for
1030 the number of calls to and the amount of time spent in
1031 various system calls, smb transactions and nmbd activity. See
1032 the file profile.h for a complete listing of the information
1033 collected. Sample code for a samba pmda (collection agent
1034 for Performance Co-Pilot) has been included in the pcp
1037 To enable the profile data collection code in samba, you must
1038 compile samba with profile data support (run configure with
1039 the --with-profiling-data option). On startup, collection of
1040 data is disabled. To begin collecting data use the smbcontrol
1041 program to turn on profiling (see the smbcontrol man page).
1042 Profile information collection can be enabled for nmbd, all smbd
1043 processes or one or more selected processes. The profiling
1044 data collected is the aggregate for all processes that have
1047 With samba compiled for profile data collection, you may see
1048 a very slight degradation in performance even with profiling
1049 collection turned off. On initial tests with NetBench on an
1050 SGI Origin 200 server, this degradation was not measurable
1051 with profile collection off compared to no profile collection
1052 compiled into samba.
1054 With count profile collection enabled on all clients, the
1055 degradation was less than 2%. With full profile collection
1056 enabled on all clients, the degradation was about 8.5%.
