2 Release Notes for Samba 3.4.2
4 =============================
7 This is a security release in order to address CVE-2009-2813, CVE-2009-2948
11 In all versions of Samba later than 3.0.11, connecting to the home
12 share of a user will use the root of the filesystem
13 as the home directory if this user is misconfigured to have
14 an empty home directory in /etc/passwd.
17 If mount.cifs is installed as a setuid program, a user can pass it a
18 credential or password path to which he or she does not have access and
19 then use the --verbose option to view the first line of that file.
20 All known Samba versions are affected.
23 Specially crafted SMB requests on authenticated SMB connections can
24 send smbd into a 100% CPU loop, causing a DoS on the Samba server.

205 =============================
206 Release Notes for Samba 3.4.0
208 =============================
211 This is the first stable release of Samba 3.4.
214 Major enhancements in Samba 3.4.0 include:
215 ------------------------------------------
217 Configuration changes:
218 o The default passdb backend has been changed to 'tdbsam'!
221 o Samba4 and Samba3 sources are included in the tarball
223 Authentication Changes:
224 o Changed the way smbd handles untrusted domain names given during user
228 o Various fixes including printer change notificiation for Samba spoolss
232 o The remaining hand-marshalled DCE/RPC services (ntsvcs, svcctl, eventlog
233 and spoolss) were replaced by autogenerated code based on PIDL.
234 o Samba3 and Samba4 do now share a common tevent library.
235 o The code has been cleaned up and the major basic interfaces are shared with
237 o An asynchronous API has been added.
240 Configuration changes
241 =====================
244 The default passdb backend has been changed to 'tdbsam'! That breaks existing
245 setups using the 'smbpasswd' backend without explicit declaration! Please use
246 'passdb backend = smbpasswd' if you would like to stick to the 'smbpasswd'
247 backend or convert your smbpasswd entries using e.g. 'pdbedit -i smbpasswd -e
250 The 'tdbsam' backend is much more flexible concerning per user settings
251 like 'profile path' or 'home directory' and there are some commands which do not
252 work with the 'smbpasswd' backend at all.
258 On the way towards a standalone Samba AD domain controller, Samba3 and Samba4
259 branches can be built as "merged" build. That's why Samba3 and Samba4 sources
260 are included in the tarball. The merged build is possible in Samba 3.4.0, but
261 disabled by default. To learn more about the merged build,
262 please see http://wiki.samba.org/index.php/Franky.
264 According to this one, there is no "source" directory included in the tarball at
265 all. Samba3 sources are located in "source3", Samba4 sources are located in
266 "source4". The libraries have been moved to the toplevel directory.
268 To build plain Samba3, please change to "source3" and start the build as usual.
269 To build Samba4 as well, please use the "--enable-merged-build" configure
273 Authentication Changes
274 ======================
276 Previously, when Samba was a domain member and a client was connecting using an
277 untrusted domain name, such as BOGUS\user smbd would remap the untrusted
278 domain to the primary domain smbd was a member of and attempt authentication
279 using that DOMAIN\user name. This differed from how a Windows member server
280 would behave. Now, smbd will replace the BOGUS name with it's SAM name. In
281 the case where smbd is acting as a PDC this will be DOMAIN\user. In the case
282 where smbd is acting as a domain member server this will be WORKSTATION\user.
283 Thus, smbd will never assume that an incoming user name which is not qualified
284 with the same primary domain, is part of smbd's primary domain.
286 While this behavior matches Windows, it may break some workflows which depended
287 on smbd to always pass through bogus names to the DC for verification. A new
288 parameter "map untrusted to domain" can be enabled to revert to the legacy
295 The spoolss subsystem was replaced by autogenerated code based on PIDL. That fixes
296 several printing issues including printer change notificiation on Samba print
297 servers and will stabilize the printing functionality generally.
298 The support for spoolss printing with Windows Vista has been improved.
304 The remaining hand-marshalled DCE/RPC services (ntsvcs, svcctl, eventlog and
305 spoolss) were replaced by autogenerated code based on PIDL.
306 So Günther Deschner finally corrected one of the biggest mistakes in the
307 development of Samba: Hand-marshalled RPC stubs.
311 Samba3 and Samba4 do now share a common tevent library for fd and timer events.
313 The code has been cleaned up and Samba3 and Samba4 do share the major basic
314 interfaces now. That is why the libraries were moved to the toplevel directory.
315 That is one of the first steps to share code and minimize the gap between
318 An asynchronous API has been added.
