WHATS NEW IN Samba 2.0.7

---

This is the latest stable release of Samba. This is the version
that all production Samba servers should be running for all current
bug-fixes.

New Documentation in 2.0.7

---

O’Reilly and Associates have donated their book “Using Samba” to
the Samba community to be updated in a collaberative way along with
the Samba software. Starting with this release the html of “Using
Samba” will be distributed with the Samba software as the online
documentation for Samba. Bug fixes for the book are encouraged as
is new material. Please help us make this documentation the best it
can be for Samba !

SWAT (Samba Web Administration Tool) has been updated to add a
link to the full text of “Using Samba” from the start screen.

Note that this does not mean that the other documentation (man
pages especially) are being abandoned. The Samba Team is still
committed to updating and improving *all* the documentation shipped
with Samba.

Also, as the source code for the book is moved into a more
manageable format (not raw HTML) we are committed to making it
available for editing by all interested parties. The current
situation of only shipping HTML with the Samba software is a first
attempt at getting this documentation integrated with the Samba
software and should not be regarded as the only way in which this
material will be made available (it was just the quickest way to
get the book integrated into 2.0.7 :-).

Windows 2000 Issues

---

This version of Samba has been tested with Windows 2000 and the
five known incompatibilities with Windows 2000 have been fixed. See
the “Changes in 2.0.7” list below for details.

New/Changed parameters in 2.0.7

---

There is a new option to the autoconf “./configure” script. This
is the “–with-utmp” (and attendant “–without-utmp”) option.
Running configure with this option will cause smbd to attempt to
use utmp accounting for users who log on and log off to the Samba
server.

There are 5 new parameters in the smb.conf file.

utmp
utmp dir
utmp hostname
utmp consolidate
wtmp directory

These parameters are only available if the “–with-utmp” option
was selected at configure time. The yes/no option “utmp” specifies
whether utmp records should be recorded on user logon/logoff. It
defaults to “no”. The “utmp dir” and “wtmp dir” are string
parameters specifying pathnames to the directories containing the
utmp/wtmp file databases. See the smb.conf man page for more
details.

inherit permissions

This boolean parameter causes newly created files and
directories to inherit their initial permissions from their parent
directory. This can be very useful in propagating such things as
the set-group bit in directory heirarchies. See the smb.conf man
page for more details.

write cache size

This integer parameter specifies (in bytes) the size of a user
level per-file write cache that smbd will create for an oplocked
file. This can improve performance significantly for writing files
by causing writes to be done in large chunk sizes. If this
parameter is set (it defaults to zero which means no write cache)
to the stripe size of a raid volume then it will cause writes to be
much more efficient. Up to 10 write caches can be active
simultaneously per smbd (allocated for the first 10 oplocked file
opens). All normal warnings about the dangers of user level caching
of data apply. See the smb.conf man page for more details.

source environment

This pathname parameter causes Samba to read a list of
environment variables from a named file on startup. This can be
useful in setting up Samba in a clustered environment. See the
smb.conf man page for more details.

Ability to delete users added

---

SWAT and smbpasswd can now delete users from the Samba smbpasswd
file. See the man page for smbpasswd for details.

Roving profile behavior finalized

---

The change in behavior with roving profiles (using the “logon
home” parameter instead of the “logon path” parameter) introduced
in 2.0.6 has been discovered to be consistant with the way Windows
NT behaves, and has been left as the default action. Please see the
additional notes in the “logon home” parameter description in the
smb.conf man page for more details.

Changes in 2.0.7

---

1). Fix for the semaphore promblems when compiling Samba with
gcc on SGI IRIX 6.5.x.
2). Quota support for Veritas filesystem added by David Lee.
3). Incoming RPC code re-written to support multiple PDU input from
the client. This should make the RPC subsystem more robust.
4). Fix from Ying Chen @ IBM to inline many frequently called
functions. This decreased CPU usage by 10%.
5). Fix from Ying Chen @ IBM to use a hash table to lookup entries
in the file cache. This is a significant improvement over the old
linked-list lookup code.
6). smbclient issues with native language support fixed. smbclient
now uses UNIX filename character sets exclusively when
communicating with libsmb library.
7). smbclient fix to not print error messages when “putting” an
empty file.
8). smbclient fix to cope with spaces in filenames when
recursing.
9). Improved error reporting in smbclient when getting browse
lists.
10). NetBIOS “scope” now supported in all Samba code/tools.
11). New mapping from code page 850 to UNIX “roman8” character
set.
12). Fix for crash bug if debug file handle couldn’t be opened.
13). Fix to allow mkdir to correctly set the high order permissions
bits for UNIX’s that don’t allow this by default.
14). Fix to dynamically allocate group array for setgroups. Don’t
depend on NGROUPS_MAX being correctly defined in header files.
15). Fix for crash bug in floating point in snprintf.
16). “Safe” version of popen() included to allow use in code such
as “source environment” patch.
17). Fix for SWAT for trailing ‘n’ in asctime().
18). Wildcard match fix from weidel@multichart.de for NT wildcard
processing.
19). unix_mask_match fixes for “veto files” parameter.
20). Fix for system call bug when configuring on Linux kernel 2.0.x
with glibc2.1.x.
21). SO_REUSEPORT socket option added for HPUX.
22). All recv() calls changed back to read() to fix Solaris 2.5.x
bug.
23). Some UNICODE conversion fixes. Not complete yet.
24). NetShareEnum fix for Windows 2000. Don’t ask for 64K as Win2k
can’t cope with this (returns “Out of memory” error).
25). Fixes for cli_error() crashes.
26). Fix for crash when connecting to password server by DNS name
not NetBIOS name.
27). Fix bug in demangling of compacted NetBIOS names.
28). Fixes for slow locking code for VMS.
29). Reply to short NetLogon packet in nmbd with short reply.
30). Correctly allign userdata to prevent crashes in nmbd.
31). Use talloc() in string buffer rotation code to prevent
overwrites.
32). Added multi-byte awareness to parameter loading code.
33). Re-wrote password file modification code. We can now delete
users atomically. Original patch from Bruce Tenison.
34). Fixed bug in parsing smbpasswd type entries.
35). Fixes from HP to the windows registry RPC emulation.
36). Added ability to return RPC fault PDU to unknown calls. Needed
to allow Windows 2000 to return UNIX permissions as NT ACLs.
37). utmp code patch from T.D.Lee@durham.ac.uk. Not available on
all platforms – test with ./configure.
38). Inherit permissions fix from David Lee.
39). Added write caching code for oplocked files.
40). Workaround for new bug in Windows 2000 where NT file create
using NTtransact call sends UNICODE without bothering to set the
UNICODE flag bit.
41). Workaround for new bug in Windows 2000 where it attempts to
re-write existing ACLs to make them inherit only.
42). Removed unused mmap code.
43). Added correct implementation of share mode deny table. We now
match Windows NT.
44). Fix recursion bug with group enumeration.
45). Fix from Bjart Kvarme to take into account changed machine
passwords that haven’t yet propagated from PDC to BDC.
46). Correctly skip two byte length field when accepting RPC “start
of message” packets in SMBwriteX on pipes.
47). Added auto-detection of Windows 2000 clients.
48). Fix bug with rollback of POSIX locks if a lock in a range
fails to apply.
49). Fix bug with registering startup smbd’s in flat file.
50). Ensure usernames are converted correctly between DOS codepages
and UNIX character sets.
51). Fix for timestamps being set incorrectly on copied files from
Paul Eggert.

servers from Christoph Pfisterer.
54). Fix for WINS server code where “do you still want name?”
request was being sent to the wrong IP address.
55). Fixed “recursion desired” bits set in nmbd so we are identical
to Windows NT.
56). nmbd now should process logon packets from Win95, Win98 and
both versions of the NT logon packet.
57). Correctly set parameter offset value for first trans2
reply.
58). Win2K will only accept volume labels in UNICODE.
59). Ensure nmbd doesn’t attempt to use the loopback interface when
registering names.
60). Fixed bug where smbd didn’t return ‘.’ or ‘..’ on top level
share directory listing.
61). Fix for soft quotas not being set (make them equal to
hardquota) from Norbert Püschel
(Pueschel.Norbert@Walzbarren-VAW.ne.uunet.de).
62). SWAT fixes for SCO UnixWare (SIGPIPE handling).
63). Fix for nmbd DOS with redirect recursion.
64). Fix for log files growing without bound from Mattias
Gronlund.
65). Fix for smbd crash bug in truncate is locked.
66). Memory leak fix in mangle name code.

New/Changed parameters in 2.0.6

---

There are 6 new parameters in the smb.conf file.

wins hook

This parameter allows an external program to be called on all
changes to a Samba WINS database, allowing dynamic DNS updates.

debug hires timestamp
debug pid
debug uid

The above 3 parameters provide greater debug information.

preexec close
rootpreexec close

The above 2 parameters control the action taken on the success
or failure of a ‘preexec’ script.

There is also one removed parameter.

mangle locks

The addition of these new parameters and the removal of the old
is described in more detail in the smb.conf man page,

When using “security=domain” the “password server” parameter can
now be set to the string “*’, which will cause Samba to search for
Domain controllers in the same way that Windows NT does. See the
smb.conf man page for more details.

The “interfaces” parameter in smb.conf can now be dynamically
detected on startup and can also now take an interface name such as
eth0. See the smb.conf man page for the details on the new features
of the “interfaces” parameter. nmbd has been enhanced to use this
feature.

The syntax for the Linux-specific smbmount command has been
changed and is now compatible with the standard mount command. See
the modified smbmount man page for details.

Support for the UNIX CUPS printer standard has been added. See
www.cups.org for details. Thanks to the folks at Easy Software
Products for this code. Set the printcap name to “cups” to enable
this. See the smb.conf man page for details.

Changes in 2.0.6

---

1). 64-bit locking removed from Linux autoconf build. This fixes
several Linux specific locking issues.
2). Crash bug fix in smbclient recursive processing. Fix from E.
Jay Berkenbilt (ejb@ql.org).
3). “history” command added to smbclient if readline available.
4). smbtar – updates files and directory message on restore.
5). smbmnt – ‘u’, ‘g’, ‘r’, ‘f’, ‘d’ options added by Andrew. See
man page for details.
6). smbmount updated to be useable by autofs on Linux. See the
samba/examples/autofs/README file for details.
7). Bug fixed where TCP_NODELAY was not being used by default in
smbd.
8). Many oplock fixes. Samba now waits 30 seconds, not 45. Also
smbd no longer aborts on client break failure, but logs a message
and continues. This is what NT does. This should fix many “oplock
break” message problems people have been having.
9). New code from Andrew to dynamically detect interfaces. nmbd
will now attempt to dynamically detect interface changes and
register names as an interface goes “up”.
10). Win95 ioctl for print jobs added by Matt.
11). Mapping for ISO8859-1 extended for codepage 437 and 850.
12). Code Page 737 -> ISO-8859-7 (Greek-Hellenic) mapping
added.
13). Character strings now correctly converted from UNIX character
set format to DOS codepage when read from smb.conf or external
passwd or group files. Samba is now much more careful about what
format external strings should be converted to/from.
14). snprintf crash fix for IRIX 6.2 and below.
15). Increased timestamp debug fixes (adds milliseconds and uid/pid
if requested).
16). Optimisation for wildcard exact match requests.
17). Win95 wildcard semantics fix – unused code removed.
18). ‘mangle locks’ parameter removed. This now done
automatically.
19). setXid() routines re-written to provide asserts and also to
fix AIX versions prior to 4.1.x.
20). MSG_WAITALL optimisation removed due to bugs in FreeBSD.
21). Length fix when writing UNICODE string.
22). oplock processing added to libsmb client code.
23). Added more client error message strings.
24). Fix bug with connecting to encrypted server when non-encrypted
password given.
25). In security=domain, password server extended to search for
DC’s if parameter = ‘*’.
26). “root did not create samaphore” bug fixed.
27). random generator initialized early to prevent icons not
showing up in Win9x.
28). Logging fix after SIGHUP.
29). WINS hook external call added when nmbd is a WINS server.
30). Support for CUPS printer protocol added by Michael Sweet.
31). Support for NIS+ backend password database updates.
32). Handle dashes in print job id’s. Fix from
Dom.Mitchell@palmerharvey.co.uk
33). Race condition in UNIX password sync on some platforms fixed
by Matt.
34). Dirptr leak from Win98 fixed.
35). Logic bug in handling of level II oplocks fixed.
36). smbd crash bug fix when opening directories.
37). Paranoia oplock fix from Charles Hoch (hoch@exemplary.com)
38). Fix Win2k problem where DCE/RPC is done on SMBwrite as well as
SMBwriteX.
39). Fix Win95 redirector alignment bug that caused oplock break
failures.
40). Preexec close code added.
41). Extra sanity checks in testparm code.
42). oplock tests added to smbtorture.
43). Tell SWAT user if logged in as root or not.
44). Solaris packaging fixes donated by VERITAS.
