125 Release Notes for Samba 3.5.1
126 March 8, 2010
127 =============================
130 This is a security release in order to address CVE-2010-0728.
133 o CVE-2010-0728:
134 In Samba releases 3.5.0, 3.4.6 and 3.3.11, new code
135 was added to fix a problem with Linux asynchronous IO handling.
136 This code introduced a bad security flaw on Linux platforms if the
137 binaries were built on Linux platforms with libcap support.
138 The flaw caused all smbd processes to inherit CAP_DAC_OVERRIDE
139 capabilities, allowing all file system access to be allowed
140 even when permissions should have denied access.
143 Changes since 3.5.0
144 -------------------
147 o Jeremy Allison <jra@samba.org>

175 Release Notes for Samba 3.5.0
176 March 1, 2010
177 ===============================
180 This is the first stable release of Samba 3.5.
183 Major enhancements in Samba 3.5.0 include:
185 General changes:
186 o Add support for full Windows timestamp resolution
187 o The Using Samba HTML book has been removed.
188 o 'net', 'smbclient' and libsmbclient can use credentials cached by Winbind.
189 o The default value of "wide links" has been changed to "no".
191 Protocol changes:
192 o Experimental implementation of SMB2
194 Printing Changes:
195 o Add encryption support for connections to a CUPS server
197 Winbind changes:
198 o Major refactoring
199 o Asynchronous
201 VFS modules:
202 o New vfs_scannedonly module has been added.
205 General changes:
206 ================
208 Support for full Windows timestamp resolution has been added. This effectively
209 makes us use Windows' full 100ns timestamp resolution if supported by the
210 kernel (2.6.22 and higher) and the glibc (2.6 and higher).
212 The Using Samba HTML book has been removed from the Samba tarball.
213 It is still available at http://www.samba.org/samba/docs/using_samba/toc.html.
215 Samba client tools like 'net', 'smbclient' and libsmbclient can use the user
216 credentials cached by Winbind at logon time. This is very useful e.g. when
217 connecting to a Samba server using Nautilus without re-entering username and
218 password. This feature is enabled by default and can be disabled per application
219 by setting the LIBSMBCLIENT_NO_CCACHE environment variable.
221 The default value of "wide links" has been changed to "no" to avoid an insecure
222 default configuration ("wide links = yes" and "unix extensions = yes"). For
223 more details, please see http://www.samba.org/samba/news/symlink_attack.html.
226 Protocol changes
227 ================
229 An EXPERIMENTAL implementation of the SMB2 protocol has been added. SMB2 can be
230 enabled by setting "max protocol = smb2". SMB2 is a new implementation of the
231 SMB protocol used by Windows Vista and higher.
233 Printing Changes
234 ================
236 A new parameter "cups encrypt" has been added to control whether connections to
237 CUPS servers will be encrypted or not. The default is to use unencrypted
238 connections.
240 Winbind changes
241 ===============
243 The Winbind daemon has been refactored internally to be asynchronous. The new
244 Winbind will not be blocked by running 'getent group' or 'getent passwd'.
246 VFS modules
247 ===========
249 A new VFS module "scannedonly" has been added. This is a filter that
250 talks to an antivirus-engine and stores whether a file is clean or not.
251 Users do only see clean files on their filesystem.
