All messages that get logged are now preceded with <virtualhost> (remote host[remote ip]). - mod_ldap for authentication against LDAP directories is now in place. - ftpwho/ftpcount -- a grammatical error corrected, and they now build as seperate binaries. - Fixed the 'no names, just UIDs' bug. - Added genuser.pl to facilitate AuthUserFile entry creation. - Umask now takes an optional second argument, specifying a directory umask. - Work around FreeBSD's broken setpassent(), and a new option to override this in fixed versions of FreeBSD's libc (--enable-force-setpassent). - Generate RPMs for both inetd and standalone versions of ProFTPD. - Added AuthUsingAlias to allow for more fine-grain control of anonymous logins. - Added support for 'TYPE L 8' and 'TYPE L 7' per RFC 959. --- NEW FILE --- 1.3.3 Release Notes ------------------------ This file contains a description of the major changes to ProFTPD for the 1.3.3 release cycle, from the 1.3.3rc1 release to the 1.3.3 maintenance releases. More information on these changes can be found in the NEWS and ChangeLog files. 1.3.3b --------- + Fixed SFTP directory listing bug + Avoid corrupting utmpx databases on FreeBSD + Avoid null pointer dereferences during data transfers + Fixed "AuthAliasOnly on" anonymous logins 1.3.3a --------- + Added Japanese translation + Many mod_sftp bugfixes + Fixed SSL_shutdown() errors caused by OpenSSL 0.9.8m and later + Fixed handling of utmp/utmpx format changes on FreeBSD 1.3.3 --------- + Fixed mod_ban whitelisting using mod_ifsession. + Fixed per-user/group/class "HideFiles none" configurations. 1.3.3rc4 --------- + Fixed mod_tls compilation using OpenSSL installations older than 0.9.7. + Fixed mod_sftp compilation on AIX. + Fixed RADIUS authentication on 64-bit platforms + Fixed memory leak in SCP downloads. + New configuration directives SQLPasswordUserSalt The SQLPasswordUserSalt directive can be used to configure per-user salt data to be added to the encrypted password for a user. The salt can be the user name, or it can be the result of a SQL query. More information can be found in doc/contrib/mod_sql_passwd.html#SQLPasswordUserSalt. 1.3.3rc3 --------- + Added Taiwan translation. + Added support in mod_sftp for the following SFTP extensions: check-file copy-file vendor-id version-select pos...@op... fst...@op... st...@op... + Added a workaround in mod_tls to deal with the vulnerability found in SSL/TLS protocol during renegotiation (CVE-2009-3555). Good descriptions of this vulnerability can be found here: http://extendedsubset.com/?p=8 http://www.educatedguesswork.org/2009/11/understanding_the_tls_renegoti.html The workaround implemented in mod_tls (Bug#3324) is one of the suggested mitigation approaches: the server now refuses all client-initiated SSL/TLS session renegotiations. + Updated to the bundled libtool to 2.2.4 (plus patch) to deal with a libtool vulnerability (CVE-2009-3736). + Added support for SHA256 and SHA512 passwords to the mod_sql_passwd module. + New configuration directives SFTPExtensions The SFTPExtensions directive can be used to selectively enable/disable mod_sftp's support for specific SFTP extensions. See doc/contrib/mod_sftp.html#SFTPExtensions for more details. + Changed configuration directives CapabilitiesSet The CAP_FOWNER capability can now be explicitly requested when using the mod_cap module: <IfModule mod_cap.c> CapabilitiesSet +CAP_FOWNER </IfModule> For operations allowed on files, this capability overrides the restriction that the file owner ID must match the process user ID. 1.3.3rc2 --------- + When handling .ftpaccess files, proftpd was merging them into the main configuration such that the .ftpaccess files configurations would override the main configuration. This was never the intended behavior, and has been fixed (Bug#3279). However, this does mean that sites which use .ftpaccess files may see a change in the behavior of their proftpd. + Changed scoreboard format (Bug#3286), need for "ServerType inetd" server to manually delete their old ScoreboardFiles. Otherwise they will see "error opening scoreboard: bad version (too old)" errors. + Changed SQL connection policy (Bug#3290). Important for clients which connect but don't authenticate (e.g. mod_ban, mod_dnsbl, mod_wrap2_sql, etc which will reject connected clients prior to authentication); saves on unnecessary database connections in such cases. For sites which require the old behavior, there is a new "PERCONNECTION" connection policy. NOTE: If you are using mod_sql for logging purposes only, e.g. you have the following in your mod_sql config: SQLEngine log then this connection policy change may affect you. If the database connection is opened after a chroot has occurred (via DefaultRoot or <Anonymous> login), the database connection may fail. And since now the connection is delayed until first use, and the first use for logging may occur after the chroot, the logging may fail. For such sites, then, you will need to use the "PERCONNECTION" connection policy explicitly. + Support for "implicit" FTPS. To enable this, use: TLSOptions UseImplicitSSL WARNING: Using this setting will cause mod_tls to handle ALL connections to the vhost as implicit FTPS connections. It is NOT possible to support both plain FTP (or explicit FTPS) clients AND implicit FTPS clients on the same address/port. Therefore this setting should ONLY ever be used in order to support braindead/broken FTPS clients, and then only for as long as it takes to fix/replace those broken clients. Note that "implicit" FTPS was explicitly DROPPED from the RFC which defines FTP over SSL/TLS; the only clients which use this feature are outdated clients based on older, now-invalidated versions of the specification. Please update your FTPS clients to one which uses explicit FTPS as soon as possible. + Re-enable turning off the Nagle algorithm; this drastically helps speed up transfers of multiple small files. + New modules mod_sql_passwd This module supports MD5 and SHA1 passwords, encoding using base64 or hex, from SQL tables. See doc/contrib/mod_sql_passwd.html for details. + New configuration directives AuthUnixOptions In Bug#1896, support for checking some AIX-specific functions for whether a login should be accepted was added; this happens only on AIX server, of course. However, some AIX admins like to configure "rlogin=false", yet still want to allow FTP logins. To enable this specific behavior, a new AuthUnixOptions directive was added, with a setting which is only honored on AIX: AuthUnixOptions aixNoRLogin If this setting is used on any other server, it is silently ignored. Bug#3300 has the full details. + Changed configuration directives ExtendedLog You can now disable logging in an <Anonymous> section to an ExtendedLog which was opened outside of the <Anonymous> section, i.e.: ExtendedLog /path/to/ext.log ALL <Anonymous /path/to/anon> ... ExtendedLog /path/to/anon-ext.log ALL # Disable the logging to the higher-level ExtendedLog by # configuring again here, but changing the command class to 'NONE' ExtendedLog /path/to/ext.log NONE ... </Anonymous> HiddenStores The HiddenStores directive can now be used to customize and change the prefix which is prepended to the HiddenStore files. The default prefix is ".in.", but if you wish to use a different prefix for any reason, you can use something like: HiddenStores foo This will cause the prefix to be ".foo.". SQLOptions When the connection to the database is lost, mod_sql now will try only once to automatically reconnect (if such reconnect functionality is supported by the database, e.g. MySQL or Postgres). To disable this reconnect behavior, there is a new "noReconnect" SQLOptions setting: SQLOptions noReconnect See Bug#3270 for the full details of this behavior change. It should be transparent for most sites. 1.3.3rc1 --------- + Added French, Bulgarian, Korean translations. + RPM 4.2 or later is required by the proftpd.spec file provided in the distribution. + If the --localstatedir configure option is used, proftpd's build system used to automatically append "/proftpd" to the configured path. This behavior has been fixed; proftpd's build system will now use the configured --localstatedir path as is. Note that this may cause issues if you have an existing build script for compling proftpd; the expected locations of files under the --localstatedir path will change. + New command-line options: The -S, --serveraddr command-line option has been added. This option can be used to specify the IP address of the host machine. By default, proftpd attempts to resolve the host IP address by using DNS resolution of the hostname. However, in cases where DNS is not configured for the host machine, this approach does not work. To specify the desired IP address, use -S when starting proftpd, e.g.: /usr/local/sbin/proftpd -S 1.2.3.4 ... And if you want proftpd to listen on all interfaces, you can specify a wildcard socket using an IP address of 0.0.0.0: /usr/local/sbin/proftpd -S 0.0.0.0 ... + New modules: mod_exec This module enables execution of external scripts based on actions/events during a session. See doc/contrib/mod_exec.html for details. mod_sftp This module implements the SSH2, SFTP, and SCP protocols. See doc/contrib/mod_sftp.html for more information. mod_sftp_pam This module uses PAM to provide a 'keyboard-interactive' SSH2 authentication method for mod_sftp. More information can be found in the documentation for mod_sftp_pam, in doc/contrib/mod_sftp_pam.html. mod_sftp_sql This module uses SQL (via mod_sql) for looking up authorized SSH2 public keys for user and hostbased authentication. More information is available in doc/contrib/mod_sftp_sql.html. mod_shaper This module can be used to provide data transfer rate "shaping" across the entire server. See the documentation at doc/contrib/mod_shaper.html. mod_tls_shmcache This module provides an external SSL session cache using shared memory; see the TLSSessionCache configuration directive. More information on this module can be found in doc/contrib/mod_tls_shmcache.html. + New configuration directives: RewriteHome The RewriteHome directive can be used to support rewriting the home directory for a user, based on regular expression rules. One such use case is where some portion of the home directory is retrieved e.g. from an LDAP directory, but you need to apply some custom prefix to the LDAP attribute. To enable this feature, first you need to add the following to your proftpd.conf: RewriteHome on Next, you need to configure the mod_rewrite rules for rewriting your home directory; this feature depends on mod_rewrite for the rewriting. The pseudo-command used by mod_rewrite for rewriting home directories is "REWRITE_HOME". Thus would you use: <IfModule mod_rewrite.c> RewriteEngine on RewrlteLog /path/to/rewrite.log RewriteCondition %m REWRITE_HOME RewriteRule (.*) /my/new/prefix$1 </IfModule> ScoreboardScrub The ScoreboardScrub directive can be used to turn on/off proftpd's periodic "scrubbing" of its ScoreboardFile, where the ScoreboardFile is scanned for entries of dead sessions: ScoreboardScrub on|off|secs Note that if scoreboard scrubbing is turned off, the ScoreboardFile can still be scrubbed on demand, either by using mod_ctrls_admin's "ftpdctl scoreboard scrub" action, or by using the new ftpscrub command-line utility. TLSControlsACLs With the addition of support for external session caches, the mod_tls module now supports some ftpdctl actions for interacting with those session caches. The TLSControlsACLs directive can be used to configure ACLs for the ftpdctl actions supported by mod_tls, and is analogous to other ACLs directives for other modules which support ftpdctl actions. TLSPKCS12File The TLSPKCS12File directive of the mod_tls module is used to configure mod_tls to use the certificate and private key contained in the indicated PKCS#12 file. Some sites already use PKCS#12 files for containing their other certificates, and thus find it useful to have PKCS#12 support in mod_tls. TLSSessionCache The TLSSessionCache directive configures an external SSL session cache, which can be used for storing and shared SSL sessions across multiple processes. An external SSL session cache is an optional facility which speeds up parallel FTPS session connections. See doc/contrib/mod_tls.html#TLSSessionCache for more information. + Changed configuration directives: AllowOverride This directive no longer supports the optional user/group/class parameters. If you wish to have per-user/group/class conditional use of the AllowOverride directive, you will need to use the mod_ifsession module. For example, instead of: AllowOverride off user !admin you will need to use: <IfUser admin> AllowOverride on </IfUser> <IfUser !admin> AllowOverride off </IfUser> Note that the "!admin" section is necessary. If you set "AllowOverride off" unconditionally, then use a mod_ifsession context, you would end up with two AllowOverride settings, and the code might not be able to distinguish properly which setting to use. Thus you need to make both the "on" and "off" cases conditional, and mutually exclusive. Configurations which use the user/group/class conditional parameters to AllowOverride will now generate configuration errors. BanOnEvent The BanOnEvent directive of the mod_ban module now supports TimeoutLogin events. <VirtualHost> You can now specify an IP address of "0.0.0.0" in a <VirtualHost> definition. IdentLookups The default IdentLookups value is now 'off'. The RFC1413 IDENT lookup adds latency to the login process, so much so that it is a FAQ to configure "IdentLookups off". In addition, the IDENT protocol is not secure; it can easily be spoofed using man-in-the-middle attacks. Sites that require IDENT lookups must now explicitly configure "IdentLookups on". Note that in order to use IdentLookups, you must compile proftpd with the mod_ident module. If you use the --disable-ident configure option, then proftpd will not recognize the IdentLookups directive. Thus in your proftpd.conf, you should use something like: <IfModule mod_ident.c> IdentLookups on </IfModule> if you want to use RFC1413 lookups. LogFormat, SQLNamedQuery There is a new variable, %{protocol}, which describes the protocol that the client is using. This variable can have values of "ftp", "ftps", "ssh2", "sftp", and "scp". Note that for SSH2 connections, the value will be "ssh2" until SFTP or SCP channels are opened; this means that during login, the %{protocol} value will be "ssh2". There is also a new %w variable which is only valid for RNTO commands. The %w value will be the original name of the file being renamed (mnemonic: "whence" a renamed file comes). RewriteCondition, RewriteRule Use of environment variables in mod_rewrite rules is now supported via the "%{ENV:var}" syntax. SQLGroupInfo The SQLGroupInfo now supports custom queries for retrieve group information. Note that instead of a single custom query, several different queries are needed; different lookups are called for depending on the situation and configuration of mod_sql (e.g. using the 'groupset' or 'groupsetfast' SQLAuthenticate parameters). See doc/contrib/mod_sql.html#SQLGroupInfo and doc/howto/SQL.html#SQLUsersetfast for more details. SQLUserInfo The support for custom SQLUserInfo queries has been extended to support custom queries to be used when the 'userset' or 'usersetfast' SQLAuthenticate parameters are used. For more information, see doc/contrib/mod_sql.html#SQLUserInfo and doc/howto/SQL.html#SQLUsersetfast. TLSOptions The NoSessionReuseRequired option has been added. As of ProFTPD 1.3.3rc1, mod_tls only accepts SSL/TLS data connections that reuse the SSL session of the control connection, as a security measure. Unfortunately, there are some clients (e.g. curl) which do not reuse SSL sessions. To relax the requirement that the SSL session from the control connection be reused for data connections, use the following in the proftpd.conf: <IfModule mod_tls.c> ... TLSOptions NoSessionReuseRequired ... </IfModule> TLSRequired The TLSRequired directive can now be used in <Directory> sections and in .ftpaccess files. When used in these configuration contexts, only the TLSRequired values that require SSL/TLS protection on data transfers are honored. With this, it is now possible to mark specific files or directories as requiring SSL/TLS protection to be accessed via data transfer. TransferLog The "service-name" field of the TransferLog usually contains just "ftp". In order to support TransferLogs for SFTP and SCP transfers, the service-name field of the TransferLog format may now show "sftp" or "scp". It may also show "ftps" instead of "ftp", if the data transfer occurred while the client is using FTP over SSL/TLS. NOTE: This change, while correct, may cause issues for log parsers. + Deprecated configuration directives: AnonymousGroup Support for this directive has been removed. + Developer Notes If you are a module developer, then you will want to know of the following API/internals changes: * The original USER value sent by the client is no longer stored in the config tree. That is, the following no longer works: user = get_param_ptr(main_server->conf, C_USER, FALSE); Instead, the original USER value is stashes in the session.notes table. Thus the above line of code can be replaced with: user = pr_table_get(session.notes, "mod_auth.orig-user", NULL); A similar change occurred for the anonymous "password" sent, but this will probably not apply to most modules.
