============================== Release Notes for Samba 3.0.23 Jul 10, 2006 ============================== This is the latest stable release of Samba. This is the version that production Samba servers should be running for all current bug-fixes. Please read the changes in this section for details on new features and difference in behavior from previous releases. There has been a substantial amount of cleanup work done during this development cycle. We would like to thank both Coverity (http://www.coverity.com/) and Klocwork (http://www.klocwork.com/) for analyzing the Samba source code. As a result, this release includes fixes for over 400 defects. The coverage was approximately even with over 200 defects reported by each tool. Thanks very much to those people who spent time testing the release candidates and reported their findings. We would like to especially thank Thomas Borkfor his numerous reports. We believe that the final release is in much better shape in large part due to his efforts. New features in 3.0.23 include: o Improved 'make test' o New offline mode in winbindd. o New Kerberos support for pam_winbind.so. o New handling of unmapped users and groups. o New non-root share management tools. o Improved support for local and BUILTIN groups. o Winbind IDMAP integration with RFC2307 schema objects supported by Windows 2003 R2. o Rewritten 'net ads join' to mimic Windows XP without requiring administrative rights to join a domain. User and Group changes ====================== The user and group internal management routines have been rewritten to prevent overlaps of assigned Relative Identifiers (RIDs). In the past the has been a potential problem when either manually mapping Unix groups with the 'net groupmap' command or when migrating a Windows domain to a Samba domain using 'net rpc vampire'. Unmapped users are now assigned a SID in the S-1-22-1 domain and unmapped groups are assigned a SID in the S-1-22-2 domain. Previously they were assign a RID within the SAM on the Samba server. For a DC this would have been under the authority of the domain SID where as on a member server or standalone host, this would have been under the authority of the local SAM (hint: net getlocalsid). The result is that any unmapped users or groups on an upgraded Samba domain controller may be assigned a new SID. Because the SID rather than a name is stored in Windows security descriptors, this can cause a user to no longer have access to a resource for example if a file was copied from a Samba file server to a local NTFS partition. Any files stored on the Samba server itself will continue to be accessible because Unix stores the Unix gid and not the SID for authorization checks. A further example will help illustrate the change. Assume that a group named 'developers' exists with a Unix gid of 782 but this user does not exist in Samba's group mapping table. it would be perfectly normal for this group to be appear in an ACL editor. Prior to 3.0.23, the group SID might appear as S-1-5-21-647511796-4126122067-3123570092-2565. With 3.0.23, the group SID would be reported as S-1-22-2-782. Any security descriptors associated with files stored on an NTFS disk partition would not allow access based on the group permissions if the user was not a member of the S-1-5-21-647511796-4126122067-3123570092-2565 group. Because this group SID not reported in a user's token is S-1-22-2-782, Windows would fail the authorization check even though both SIDs in some respect referred to the same Unix group. The current workaround is to create a manual domain group mapping entry for the group 'developers' to point at the S-1-5-21-647511796-4126122067-3123570092-2565 SID. Passdb Changes ============== The "passdb backend" parameter no long accepts multiple backends in a chaining configuration. Also be aware that the SQL and XML based passdb modules have been removed in this release. More information of external support for a SQL passdb module can be found at http://pdbsql.sourceforge.net/. Group Mapping Changes ===================== The default mapping entries for groups such as "Domain Admins" are no longer created when using an smbpasswd file or a tdbsam passdb backend. This means that it is necessary to use 'net groupmap add' rather than 'net groupmap modify' to set these entries. This change has no effect on winbindd's IDmap functionality for domain groups. LDAP Changes ============ There has also been a minor update the Samba LDAP schema file. A substring matching rule has been added to the sambaSID attribute definition. For OpenLDAP servers, this will require the addition of 'index sambaSID sub' to the slapd.conf configuration file. It will be necessary to run slapindex after making this change. There has been no change to actual data storage schema. ###################################################################### Changes ####### smb.conf changes ---------------- Parameter Name Description Default -------------- ----------- ------- acl group control Deprecated No add port command New "" change notify timeout Changed Scope dmapi support New No dos filemode Modified No enable asu support Changed default No enable core files New Yes enable privileges Changed default Yes enable rid algorithm Removed fam change notify New Yes hosts equiv Removed host msdfs Changed default Yes msdfs root Changed default Yes open files database hash size New 10007 passdb expand explicit Changed default No strict locking Changed default auto usershare allow guests New No usershare max shares New 0 usershare owner only New Yes usershare path New ${lockdir} usershare prefix allow list New "" usershare prefix deny list New "" usershare template share New "" winbind enum users Changed default No winbind enum groups Changed default No winbind nested groups Changed default Yes winbind offline logon New No winbind refresh tickets New No winbind max idle children Removed wins partners Removed Changes since 3.0.23rc3 ----------------------- commits ------- o Jeremy Allison * BUG 3858: Ensure that all files are removed by a wildcard delete when 'hide unreadable = yes'. * Fix various issues raised by the Klocwork code analyzer. * Fix nmbd WINS serving bug causing duplicate IPs in the *<1b> query reply ("enhanced browsing = yes"). * Fix SMB signing failures in client tools. * BUG 3909: Avoid EA lookups on MS-DFS links. o Nicholas Brealey * Compile fix for pam_winbind. o Gerald (Jerry) Carter * Use system provided killproc() in RedHat init scripts for more robust shutdown. * Fix a crash in the printer publishing code when adding a new printer via the APW. * Fix broken compile of unsupported smbwrapper utility. * BUG 3905: Fix smbd startup failure caused by a failure to create an NT token for the guest account. * BUG 3908: Fix RPC bind authentication failure which broke user password changes. * Ensure that "net ads join" reports failure correctly if it cannot set the machine account password. o Guenther Deschner * Fix different extended_dn handling in adssearch.pl (Thanks to Frederic Brin at Novell). * Fix a memleak in winbindd's credentials cache. * Protect against crashes in CLDAP request processing. * Remove incomplete DfsEnum() info level to avoid an smbd crash. o Volker Lendecke * Fix a memleak in the server registry code for enumeration shares. * Fix an invalid munlock() call in winbindd's credentials cache. * Fix compile warnings when passing NULL to snprintf(). * BUG 3915: Fall back to a pure unix user with S-1-22 SIDs in the token in case anything weird is going on with the 'force user'. * CVE-2006-3403: Fix minor memory exhaustion DoS in smbd. o Jason Mader * Compiler warning fixes. o Simo Sorce * Set the correct sid type when looking up a gid.

Release Notes for older release follow: -------------------------------------------------- ============================== Release Notes for Samba 3.0.22 Mar 30, 2006 ============================== This is a security release of Samba. The Samba 3.0.21 release series (including the patch releases a through c) has been discovered to expose the clear text of the server's machine account credentials in the winbind log files when the log level is set to 5 or higher. This defect has been assigned the CVE number CAN-2006-1059. Summary ======= The machine trust account password is the secret shared between a domain controller and a specific member server. Access to the member server machine credentials allows an attacker to impersonate the server in the domain and gain access to additional information regarding domain users and groups. The winbindd daemon included in Samba 3.0.21 and subsequent patch releases (3.0.21a-c) writes the clear text of server's machine credentials to its log file at level 5. The winbindd log files are world readable by default and often log files are requested on open mailing lists as tools used to debug server misconfigurations. This affects servers configured to use domain or ads security and possibly Samba domain controllers as well (if configured to use winbindd). ======= -------------------------------------------------- =============================== Release Notes for Samba 3.0.21c Feb 24, 2006 =============================== Common bugs fixed in 3.0.21c include: o Access checks when deleting printer driver meta-data. o Several non-default combinations schannel and SPNEGO support. o Password changes with NT4 and Win2k pre-SP4 clients. o High load issues on IRIX caused by a bug when interfacing with kernel oplocks. ###################################################################### Changes ####### Changes since 3.0.21b --------------------- commits ------- o Michael Adam * Add popt to the include path for examples/VFS. o Jeremy Allison * Fix bug in the USC2 macros on big-endian CPUs. * Filter deleted oplocks from the output of smbstatus. * Remove invalid test check_for_pipe(). * BUG 3515: Fix kernel oplock support on IRIX. * BUG 3522: Fix return value for mkdir request when the directory already exists. * BUG 3526: Add missing FindNext info levels (diagnosed by Corinna Vinschen). * BUG 3330: Fix username parsing in Kerberos PAC (based on work by Guenther). * BUG 3512: Fix cause of "use spnego=no" and "server signing=auto" resulting in a client disconnect after negprot. * BUG 3510: Fix 'net join' against a server with client schannel disabled. * Fix negprot bug causing a 2k client with cached domain credentials to refuse to connect to a standalone Samba host. * Ensure that the correct error is checked when encountering a socket error (fixes crashes in winbindd). o Andrew Bartlett * Fix domain joins from NT4 clients and password changes. o Richard Bollinger . * Compile fix in pdbedit. o Gerald (Jerry) Carter * Break RHEL/Fedora packaging out to include a samba-docs rpm. * Remove use of /var/cache/samba from RHEL/Fedora packaging. * Fix bug in loadparm.c that caused builtin services to be also listed as external services (e.g. Spooler, NETLOGON, etc..). * Fix bug in the samr dispinfo enumeration code. * Add earlier checks to deny deleting a printer driver meta-data. o Guenther Deschner * Add Account Policy LDAP attributes for eDirectory schema. o William JoJo * BUG 1870: Make nmblookup do a node status on all IP's when requested. * BUG 2353: Fix clitar -F processing. o Volker Lendecke * Fix the build for --with-aio-support. * Fix remote password changing if password must change is set. * Fix rpcclient to obey the -W parameter. * Fix segv in smbmount and the profiles tool. * Fix typo in pdbedit help text (reported by Karolin Seeger). o Vladimir Lettiev * Honour the $(DESTDIR) Makefile variable when installing Python extensions. o Jason Mader * Compiler warning fixes. o Lars Müller * Fix python build with older python versions. * Update dhcp.conf files in Debian packaging * SWAT welcome file updates * Compiler warning fixes. * Add .2 to the SONAME as version suffix if we link the nss modules on linux. * Add -t|--password-from-stdin option to pdbedit. o James Peach * Continue not enabling valgrind on 64-bit Linux. o Tim Potter * Remove unused #defines. o Simo Sorce * Debian packaging updates. o Qiao Yang * Make sure to refresh the timestamp on entries in the failed connection code in winbindd. -------------------------------------------------- =============================== Release Notes for Samba 3.0.21b Jan 30, 2006 =============================== Common bugs fixed in 3.0.21b include: o Server crashes in smbd. o Compile issues on 64-bit platforms. o Crash bugs on big-endian systems. o Packaging fixes for RHEL/Fedora, Solaris, & Debian. o Over 30 bugzilla reports closed. ###################################################################### Changes ####### Changes since 3.0.21a --------------------- commits ------- o Jeremy Allison * Fix the SAMR cache across handles opens and closes. * Re-add the talloc_describe_all() function for reporting pool usage. * Merge talloc license change from Samba 4. * Fix 64-bit compile warnings reported by gcc. * Add the share path into the sharemode db. * Consistency fixes: Remove use of uint8_t -> uint8. * BUG 3346: Fix crash bug in big-endian boxes by linearizing structure when passing through the messaging API. * BUG 3421: Fix segv in the Kerberos key tab code (Thanks to Luke Deller). * Force smbd to exit if the guest account internal setup fails. * BUG 3419: vfs_full_audit fixes for multiple connections. * Ensure SWAT lists running processes. * Fix NTLMv2 interoperability bug between Samba servers. * Oplock break logic fixes. o Andrew Bartlett * BUG 3401: Fix crash bug caused by incorrect handling of weak session keys.

In short, the RPC mechanisms used by "security = domain" to retrieve users and groups is not compatible with these changes. The "security = ads" configuration is not affected by the Windows protocol changes. Samba developers are actively working to correct this problem in the 3.0.21 release. In the meantime, Administrators who are unable to migrate to "security = ads" and must continue using "security = domain", can define credentials to be used by winbindd for account enumeration by executing the following command as root. wbinfo --set-auth-user='DOMAIN\username%password' ###################################################################### Changes ####### Changes since 3.0.20 -------------------- commits ------- o Jeremy Allison * BUG 3065: Fix for legacy clients retrieving a listing of an empty directory. * Added external library for accessing Samba's share mode database. * Fix winbindd credentials chain which caused logon failures after attempting to authenticate an unknown user. * Fix recursive looping bug in winbindd. * Fix build errors on 64-bit systems. * Posix ACL memory leak and crash bug fixes. * BUG 3044: Ensure OPEN-EXEC is honored as read-only. * BUG 3060: Ensure SMBcreate truncates the file if it exists. * Hide dot files and directory logic fixes. * Correct display of open file modes by smbstatus. * BUG 3010: Fix missing files bug on AIX systems. o Gerald (Jerry) Carter * Allow the root user to automatically pass se_access_checks() in the registry and service control server code. * Ensure that winbindd uses the correct name in the net_auth2() request when running on a Samba PDC. * Fix linking problem with tdb utilities. * BUG 3080: Fix regression in 'net rpc shutdown' command. * Fix segv in 'net rpc' when the pipe open fails. * Fix upload bug when installing 64-bit Windows printer drivers. * Fix regression in the smburi syntax used by smbspool. * Fix sorting of subkey hash records in registry files. * Correct REG_CREATE_KEY_EX parsing error. * Interoperability issues with usrmgr.exe and Samba groups. * Use the display names and not the Unix names when enumerating groups in the ldapsam passdb backend. * Ensure that Windows domain user names are converted to lower case. o Guenther Deschner * Prevent BUILTIN sids returned in the user's token from a Windows DC from being applied to any local group mappings on the Samba host. * Plug memory leaks in the Kerberos keytab code. * Ensure BUILTIN groups are returned from winbindd's idmap_rid backend when 'winbind nested groups' is enabled. * Fix crash bug in winbindd caused by 64-bit build issues. * Improve debug messages in smbspool. * Give better error-message when "NDS Universal Password" change fails. * Fix password history error in the eDirectory schema file. * Ensure that Windows domain group names are converted to lower case. o Steve French * Allow disabling mandatory byte range lock mount flag, and fix corresponding entry in mtab. o Volker Lendecke * Fix race condition in the NTcreate&X open code when the disposition is NTCREATEX_DISP_CREATE. * Correct logic error when checking the pid for pending print change notify messages. * Ensure that winbindd child process complete startup even when the parent is receiving authentication requests. * Return the full NTSTATUS code to ntlm_auth and pam_winbindd when authentication fails. o Jason Mader * Compile warning fixes. o Uli Meis * Patches for pdb_*sql.c o Luke Mewburn * Autoconf syntax fixes. o James Peach * Correct problem with creating a core file in Linux. o Stefan Metzmacher * Quota fixes in smbd. o Peter Rindfuss * Patches for pdb_*sql.c o Jiri Sasek * Solaris toolchain patches for autoconf scripts. o Andrew Tridgell * Fix for tdb clear-if-first race condition. o Leo Weppelman * BUG 3104: Don't allow time updates to files on read-only shares. o Steve Williams * BUG 3052: Fix compile issues on OpenBSD. -------------------------------------------------- ============================== Release Notes for Samba 3.0.20 Aug 19, 2005 ============================== Additional features introduced in Samba 3.0.20 include: o Support for several new Win32 rpc pipes. o Improved support for OS/2 clients. o New 'net rpc service' tool for managing Win32 services. o Capability to set the owner on new files and directory based on the parent's ownership. o Experimental, asynchronous IO file serving support. o Completed Support for Microsoft Print Migrator. o New Winbind IDmap plugin (ad) for retrieving uid and gid from AD servers which maintain the SFU user and group attributes. o Rewritten support for POSIX pathnames when utilizing the Linux CIFS fs client. o New asynchronous winbindd. o Support for Microsoft Print Migrator. o New Windows NT registry file I/O library. o New user right (SeTakeOwnershipPrivilege) added. o New "net share migrate" options. What happened to 3.0.15 - 3.0.19? ================================== After some discussion it was deemed that the amount of changes going into the next Samba 3.0 release needed something to catch people's attention. Skipping several releases was chosen as the best solution with the least overhead. There will be no 3.0.15 - 3.0.19 ever released. The next production release following 3.0.20 should be 3.0.21. The original announcement about the version number change can be found in the samba mailing list archives: http://marc.theaimsgroup.com/?l=samba&m=111721010206997&w=2 Asynchronous Winbind Implementation =================================== Winbindd has been completely rewritten in this release to support an almost completely non-blocking, asynchronous request/reply model. This means that winbindd will scale much better in large domain environments and on high latency networks. Neither the client interface nor the command line tools (i.e. wbinfo) have changed in their calling conventions or syntax. However, due to internal structure changes, it is required (more so than normal) that you install the nss_winbind.so library included in this release. Support for Microsoft Print Migrator ==================================== Samba 3.0.20 includes full support for migrating printers from Windows servers or other Samba servers via the Microsoft Print Migrator tool. Restoring printers requires a working "add printer command" defined in smb.conf. Current support also allows administrators to create a master list of printer drivers which can be restored in bulk on new (or existing) Samba installations. Asynchronous IO Support ======================= Experimental support for async IO has been added to smbd for certain platforms. To enable this new feature, Samba must be compiled to include the --with-aio-support configure option. In addition, the "aio read size" and "aio write size" to non-zero values. See the smb.conf(5) man page for more details on these settings. ###################################################################### Changes ####### smb.conf changes ---------------- Parameter Name Action -------------- ------ acl check permissions New acl group control New acl map full control New aio read size New aio write size New enable asu support New inherit owner New ldap filter Removed map to guest Modified (new value added) max stat cache size New min password length Removed printer admin Deprecated username map script New winbind enable local accounts Removed winbindd nss info New Changes since 3.0.14a --------------------- commits ------- o Jeremy Allison * BUG 2533: Fix incorrect directory listings for OS/2 clients. * Ensure the old SMB search calls always ask mask_match() to translate patterns like ????????.???. * Split out the check_path_syntax() into a findfirst, findnext, & wildcard versions. * Fix checks for matching groups in an file ACL against the user's primary and supplementary group list. * BUG 2541: Ensure we recognize LANMAN2.1 as OS/2 and select LANMAN2 protocol, ensure the EA size is always correctly set on a query for a file with no EA's. * BUG 2551: Look at the incoming flags2 flag FLAGS2_LONG_PATH_COMPONENTS determines if a reply is uppercased on a SMBsearch request, not the protocol level. * Added "volume" command to smbclient that prints out the volume name and serial number. * Added "fix for broken SMB_INFO_VOLUME level used by OS/2. * Add support for OS/2 Extended Attributes. * Correctly check OpenX open modes. * Ensure allocation size is correctly returned for OpenX. * Only set allocation on create/truncate for nttrans. * Fix oplock bug in trans2open() code. * Remove unix_ERR_XXX global nastiness. * Only do the strange DOS error for openX, not trans2open. * Ensure SMBopen replies includes the share modes as well as open modes. * BUG 2581: Add size limit (in kb) to stat cache. * Fix bug in the trans2 secondary processing. * BUG 2601: Enforce DOS_OPEN_EXEC to mean read-only. * Add an SMB counter per connection struct for gathering profiling data. * BUG 2605: Ensure smbclient doesn't perform commands if the "chdir" fails in a scripted set. * Ensure a 'forced group' is added to the list of effective gids when processing ACLs. * Refactor rpc_bind structures for better future work. * BUG 2942: Add missing value in debug message. * BUG 2946: Fix regressions in str[n]cmp_w) functions found by 'mangling method = hash'. * Fix memory leaks in the msdfs trans2 server code. * Convert msdfs server to be talloc'd based. * Fix up stackable vfs interface. * Fix rpc fault when encountering an unknown rpc_bind auth type. * BUG 2954: More AIX 5.1 AIO compile fixes. * Fix valgrind bug in interaction with new aio buffer (found by Volker). * BUG 2878: Fix Norton commander not running on OS/2 clients. * Cleanup SAMR user info structure naming. * BUG 2889: Fix directly listings from OS/2 clients. * Added "acl group control" parameter. * Add debug warning if AddPrinterEx() is called without having an 'add printer command' defined. * Add better log messages when modifying ldap entries. * BUG 2829: Fix strXX_w() functions on non-x86 platforms when when string is unaligned. * BUG 2918: Fix SMB chaining by ensuring that deferred open message buffer is nor reused. * Add support for client setting capabilities to select posix pathnames on the wire. * Stop using C++ reserved words so that Samba can be compiled using g++.

Additional features introduced in Samba 3.0.12: o Performance enhancements when serving directories containing large number of files. o MS-DFS support added to smbclient. o More performance improvements when using Samba/OpenLDAP based DC's via the 'ldapsam:trusted=yes' option. o Support for the Novell NDS universal password when using the ldapsam passdb backend. o New 'net rpc trustdom {add,del}' functionality to eventually replace 'smbpasswd {-a,-x} -i'. o New libsmbclient functionality. ======================= Large Directory Support ======================= Samba 3.0.12pre1 introduces a specific mechanism for dealing with file services that frequently contain a large number of files per directory. Historically Samba's performance has suffered in such environments due to the translation from case insensitive lookups by Windows client to the case sensitive storage mechanisms used by UNIX filesystems. Configuration details along with a short HOWTO can be found at: http://www.samba.org/samba/ftp/HOWTO/Samba-LargeDirectory-HOWTO ================================== libsmbclient Binary Compatibility ================================== Please note that a change has been made to the _SMBCCTX structure in source/include/libsmbclient.h. This change is not backwards compatible with applications linked against the libsmbclient.so library from Samba 3.0.11. However, it is compatible with all other Samba 3.0.x releases. This means that it will be most likely be necessary to recompile any applications linked against the 3.0.11 version of the library. ###################################################################### Changes ####### smb.conf changes ---------------- Parameter Name Action -------------- ------ allocation roundup size New log nt token command New write cache Deprecated Changes since 3.0.11 -------------------- commits ------- o Jeremy Allison * BUG 2146: Return correct allocation sizes so as not to crash the VC++ compiler. * BUG 962: Ensure that parsing of service names in smb.conf is multibyte safe. * BUG 2201, 2227: Support new delete semantics used by MS04-044 and XP SP2. * BUG 1525: Correctly timestamps interpreted on 64-bit time_t values (patch submitted by Jay Fenlason ). * Add special hooks when serving directories containing large numbers of files. * Ensure that WINS negative name query responses and WACK packets use the correct RR type of 0xA instead of reflecting back what the query RR type was (0x20). * BUG 2310: Only do 16-bit normalization on small dfree request. * BUG 2323: Correct authentication failure when using plaintext passwords from Windows XP clients. * BUG 2146: Add new smb.conf option 'allocation roundup size' to work around issues building MS Visual Studio 6.0 project on a Samba file share while restoring the pre-3.0.21pre1 behavior by default. * BUG 2399 (partial): Ensure we use SMB_VFS_STAT instead of stat when checking for existence of a pathname. * Check the sticky bit on the parent directory for supporting the new WinXP SP2 file deletion semantics. * Various oplock, share mode, and byte range locking fixes found by Connectathon tests. * BUG 2271: Fix resume key issues in trans2FindFirst() client code (inspired by patch from Satwik Hebbar). * BUG 2382, 2045: More pending modtime and delayed write fixes for MS Excel (incorporates partial patches from ke_miyata@itg.hitachi.co.jp). * Debug log message cleanups. * Add case insensitive search for a principal match on logon verification in the system keytab (based on patch by Michael Brown ). * Revert the previous SMB signing change from Nalin Dahyabhai when using DES keys. * Add missing RESOLVE_DFSPATH() calls for older SMB commands. * Fix FindFirst() server code to deal with resume names of ".." and "."
