Changes since 2.2.8:
Digital Defense, Inc. has alerted the Samba Team to a serious
vulnerability in all stable versions of Samba currently shipping.
The Common Vulnerabilities and Exposures (CVE) project has assigned
the ID CAN-2003-0201 to this defect.
This vulnerability, if exploited correctly, leads to an anonymous
user gaining root access on a Samba serving system. All versions
of Samba up to and including Samba 2.2.8 are vulnerable. An active
exploit of the bug has been reported in the wild.

****************************************
* IMPORTANT: Security bugfix for Samba *
****************************************
The SuSE security audit team, in particular Sebastian Krahmer
<krahmer@suse.de>, has found a flaw in the Samba main smbd code which
could allow an external attacker to remotely and anonymously gain
Super User (root) privileges on a server running a Samba server.
This flaw exists in previous versions of Samba from 2.0.x to 2.2.7a
inclusive. This is a serious problem and all sites should either
upgrade to Samba 2.2.8 immediately or prohibit access to TCP ports 139
and 445. Advice created by Andrew Tridgell, the leader of the Samba
Team, on how to protect an unpatched Samba server is given at the end
of this section.
The SMB/CIFS protocol implemented by Samba is vulnerable to many
attacks, even without specific security holes. The TCP ports 139 and
the new port 445 (used by Win2k and the Samba 3.0 alpha code in
particular) should never be exposed to untrusted networks.

O_RDWR fails in fcbopen case, remember the errno from previous open_file()
call and set errno back to this value if the second open_file() call
fails too
this makes samba report EACCESS instead of confusing ENOENT if creation
of file fails due to insufficient permissions for SMBcreate/SMBmknew call
bump package revision

have it be automatically included by bsd.pkg.mk if USE_PKGINSTALL is set
to "YES". This enforces the requirement that bsd.pkg.install.mk be
included at the end of a package Makefile. Idea suggested by Julio M.
Merino Vidal <jmmv at menta.net>.

1) Fix for smbclient reporting negative file sizes on dir command
and negative statistics being reported when using put or get
on large files.
2) Fix bug in determination of allocation size
3) Fix 64bit size problems which prevented copying of files larger
than 2 GBytes.
4) Fix for xcopy /s problem with old DOS clients not sending correct
attributes on subsequent SMBsearch calls.
5) Fix bug in call to standard_sub_advanced giving a 0 length. This
fixes the string overflow in string_sub errors.
6) Correctly handle querygroup rpcclient command
7) fix broken incremental tar in smbtar command

A security hole has been discovered in versions 2.2.2 through 2.2.6
of Samba that could potentially allow an attacker to gain root access
on the target machine. The word "potentially" is used because there
is no known exploit of this bug, and the Samba Team has not been able to
craft one ourselves. However, the seriousness of the problem warrants
this immediate 2.2.7 release.
1) ensure we send the notify message in the same way it is expected
to be received by srv_spoolss_receive_message().
2) attribute matching on truncate only matters when opening truncate
with current SYSTEM|HIDDEN -> NONE. It's fine to truncate on open
with current NONE -> SYSTEM | HIDDEN.
3) Fix bug in rpcclient's deldriver command
4) Don't set global_machine_password_needs_changing if
lp_machine_password_timeout() is set to zero
5) don't parse the BUFFER5 if the buffer length is zero
6) fix core dump if pdbedit is run as non-root or smbpasswd file does
not exist
7) Ensure can_delete() returns correct error code
8) correctly return NT_STATUS_DELETE_PENDING from open code
9) fix bug that assumed dos_unistr2 length was in ucs2 units, not bytes
10) check the long_archi name is not null when deleting a printer driver.
fixes core dump in smbd when using rpcclient's deldriver
11) fix fd leak with kernel change notify on Linux 2.4 kernels
12) must add one to the extra_data size to transfer the 0 string
terminator. This was causing "wbinfo --sequence" to access past the
end of malloced memory
13) fix for large systems allowing more than 65536 files open in
NTcreate&X
14) Fix bug in %U expansion

version 2.2.4nb1 is that there are the usual minor bug fixes, plus some
important ones:
* fix printing with Win2K/XP clients
* fixes related to using LDAP for the SAM
* fixes related to changing passwords
Pkgsrc changes:
* Fetch the .tar.bz2 file -- it's smaller.
* Use smb.conf.default as the sample config file and get rid of
the homegrown files/smb.conf.sample. smb.conf.default is more
informative and is a better resource.
* Remove irrelevant examples.
* Move convert_smbpasswd script to the examples/samba/misc
directory. It's pretty much outlived it's usefulness at this
point of the Samba release cycle.

WHAT'S NEW IN Samba 2.2.4 - 2nd May 2002

NT/2k/XP clients.
* Several fixes relating to serving PC database files such

in the inclusion of a "Recycle Bin" vfs module. See

* Addition of a tool (tdbbackup) for backup/restore of Samba's
tdb's

Known Bugs
----------
* Under certain conditions when serving the MS Access 2000
executable file and an Access database from a Samba share,
it is possible to experience data corruption. This pug does
does occur when the database is served from a Samba file share
but the Access *.exe is stored on the client's local file system.
The exact reason for this bug is unknown at this time.

Change from 2.2.3
-----------------
This is a minor bugfix release for the 2.2.3 release. The 2.2.3
release had a problem that was visible to Windows 2000 Explorer
users in that copying files into a share that already existed
failed with "Access Denied" rather than asking the user if an
overwrite was required. This was due to an incorrect error mapping
between the UNIX EEXIST error code and the NT status error.
As Windows Explorer is a highly visible end user application a quick
bugfix release was required, hence 2.2.3a.
Compilation on HPUX versions earlier than HPUX 11 has also been
corrected.
The cvs.log file is no longer included with this release, as it adds
13Mb to the size of the release, and is easily available on the Web.

is not defined, as that is the only time when the smbpasswd file is
consulted. Also don't create a the smbpasswd file from /etc/passwd, as
that generates a lot of bad users, e.g. root, daemon, operator, etc.
Instead, just create an empty smbpasswd file and rely on the admin to add
approved users to the smbpasswd file using "smbpasswd -a".

|

(2) Add "piddir" as /var/run and "pidfile dir" and "pidfile directory"
statement for smb.conf.
(3) Some fix for password synchronization but it isn't tested much and
it is almost useless under "encrypt passwords = yes" environment.
Changes for INSTALL and part of Makefile are provided by
"Johnny C. Lam" <jlam@netbsd.org> and (2) and (3) are got
from FreeBSD ports.
Bump revision to 1; samba-2.2.3nb1 now.

According to Samba 2.2.3 release announcement:
Much work has been done on the LDAP backend code. The configure
option --with-ldapsam is now considered to be stable. The schema
used has changed, see the file examples/LDAP/samba.schema for the
new schema.
New documentation explaining how to set up a Samba only PDC/BDC
setup has been added in the files Samba-LDAP-HOWTO and Samba-BDC-HOWTO
in the documentation tree.

as they might not be there depending on whether INSTALL_RCD_SCRIPTS is set
in /etc/mk.conf when the package is built. Instead, assume that the other
rc.d scripts are in the same place as this "meta" script and locate them
using "dirname $0". Problem noted by Stoned Elipot <seb@netbsd.org> in
private email.

print/lprng, we make a new variable USE_CUPS that is used by packages to
determine whether depend on print/cups and to compile in support for CUPS.
USE_CUPS may be either "YES" or undefined. Deprecate SAMBA_WITH_CUPS as
its purpose is superseded by USE_CUPS. Convert net/samba and net/samba20
to use USE_CUPS and make x11/kdelibs2 respect USE_CUPS.

Fix the problem that some data files are installed into root directory,

This value may be customized in various ways:
PKG_SYSCONFBASE is the main config directory under which all package
configuration files are to be found.
PKG_SYSCONFSUBDIR is the subdirectory of PKG_SYSCONFBASE under which the
configuration files for a particular package may be found.
PKG_SYSCONFDIR.${PKGBASE} overrides the value of ${PKG_SYSCONFDIR} for a
particular package.
Users will typically want to set PKG_SYSCONFBASE to /etc, or accept the
default location of ${PREFIX}/etc.
This obsoletes the use of CONFDIR, which was active for only 6 days, so no
need to have a workaround to still accept old CONFDIR settings.
