OpenVPN 2.0发布。released on 2005.04.17
经过了29个test版-20个beta版-21个RC版----- http://openvpn.net/release/openvpn-2.0.tar.gz
2005.04.17 -- Version 2.0
* Fixed minor options string typo in options.c.
2005.04.10 -- Version 2.0-rc21
* Change license description from "GPL Version 2 or (at your
option) any later version" to just "GPL Version 2".
2005.04.04 -- Version 2.0-rc20
* Dag Wieers has put together an OpenVPN/LZO binary RPM set with
excellent distro/version coverage for RH/EL/Fedora, though
using his own SPEC. I modified openvpn.spec to follow some of
the same conventions such as putting sample scripts and doc
files in %doc rather than /usr/share/openvpn.
* Minor change to init scripts to run the user-defined script
/etc/openvpn/openvpn-startup (if it exists) before any OpenVPN
configs are started, and to run /etc/openvpn/openvpn-shutdown
after all OpenVPN configs have been stopped. The
openvpn-startup script can be used for stuff like
insmod tun.o, setting up firewall rules, or starting
ethernet bridges.
2005.03.29 -- Version 2.0-rc19
* Omit additions of routes where the network and
gateway are equal and the netmask is 255.255.255.255.
This can come up if you are using both
server/ifconfig-pool and client-config-dir with
ifconfig-push static addresses for some subset of clients
which directly reference the server IP address as the
remote endpoint.
2005.03.28 -- Version 2.0-rc18
* Packaged Windows installer with OpenSSL 0.9.7f.
* Built Windows installer with NSIS 2.06.
2005.03.12 -- Version 2.0-rc17
* "MANAGEMENT: CMD" log file output will now only occur
at --verb 7 or greater.
* Added an optional name/value configuration list to
the openvpn-auth-pam plugin module argument list. See
plugin/auth-pam/README for documentation. This is necessary
in order for openvpn-auth-pam to work with queries generated
by arbitrary PAM modules.
* In both auth-pam and down-root plugins, in the forked process,
a read error on the parent process socket is no longer fatal.
* MandrakeSoft liblzo1 RPM only Provides for a 'liblzo1'.
A conditional test of the vendor has been added to
Require the appropriately named 'lzo' (liblzo1 / lzo).
(Tom Walsh - http://openhardware.net)
2005.02.20 -- Version 2.0-rc16
* Fixed bug introduced in rc13 where Windows service wrapper
would be installed with a startup type of Automatic.
This fix restores the previous behavior of installing
with a startup type of Manual.
2005.02.19 -- Version 2.0-rc15
* Added warning when --keepalive is not used in a server
configuration.
* Don't include OpenSSL md4.h file if we are not building
NTLM proxy support (Waldemar Brodkorb).
* Added easy-rsa/build-key-pkcs12 and
easy-rsa/Windows/build-key-pkcs12.bat scripts
(Mathias Sundman).
2005.02.16 -- Version 2.0-rc14
* Fixed small memory leak that occurs when --crl-verify
is used.
* Upgraded Windows installer and .nsi script to NSIS 2.05
(Mathias Sundman).
* Changed #include backslash usage in cryptoapi.c to use
forward slashes instead (Gisle Vanem).
* Created easy-rsa/revoke-full to handle revocations in
a single step: (a) revoke crt, (b) regenerate CRL, and
(c) verify that revocation succeeded.
* Renamed easy-rsa/Windows/revoke-key to revoke-full so
that both *nix and Windows scripts are equivalent.
2005.02.11 -- Version 2.0-rc13
* Improve human-readability of local/remote options
diff, when inconsistencies are present.
* For Windows easy-rsa, distribute vars.bat.sample and
openssl.cnf.sample, then copy them to their normal
filenames (without the .sample) when init-config.bat
is run. This is to prevent OpenVPN upgrades from
wiping out vars.bat and openssl.cnf edits.
* Modified service wrapper (Windows) to use a
case-insensitive search when scanning for .ovpn files
in \Program Files\OpenVPN\config. Prior versions
required an all-lower-case .ovpn file extension.
* Miscellaneous service wrapper code cleanup.
* If --user/--group is used on Windows, treat it
as a no-op with a warning (this makes it easier to
distribute the same client config file to Windows
and *nix users).
* Warn if --ifconfig-pool-persist is used with
--duplicate-cn.
2005.02.05 -- Version 2.0-rc12
* Removed some debugging code inadvertently included
in rc11 which would print the --auth-user-pass
username/password provided by clients in the server
logfile.
* Client code for cycling through --remote list will
retry the last address which successfully authenticated
before moving on through the list.
* Windows installer will now install sample configuration
files in \Program Files\OpenVPN\sample-configs as well
as generate a start menu shortcut to this directory.
* Minor type change in buffer.[ch] to work around char-type
ambiguity bug. Caused management interface lock-ups on
ARM when building with armv4b-hardhat-linux-gcc 2.95.3.
2005.02.03 -- Version 2.0-rc11
* Windows installer will now install easy-rsa directory
in \Program Files\OpenVPN
* Allow syslog facility to be controlled at compile time,
e.g. -DLOG_OPENVPN=LOG_LOCAL6 (P Kern).
* Changed certain shell scripts in distribution to use
#!/bin/sh rather than #!/bin/bash for better portability.
* If --ifconfig-pool-persist seconds parameter is 0, treat
persist file as an allocation of fixed IP addresses
(previous versions took IP-to-common-name associations
from this list as hints, not mandatory static allocations).
* Fixed bug on *nix where if --auth-user-pass and --log
were used together, the username prompt would be sent to
the log file rather than /dev/tty.
* Spurious text in openvpn.8 detected by doclifter
(Eric S. Raymond).
* Call closelog later on daemon kill so that process
exit message is written to syslog.
2005.01.27 -- Version 2.0-rc10
* When ./configure is run with plugins enabled (the default),
check whether or not dlopen exists in libc before testing
for libdl. This is to fix an issue on FreeBSD and possibly
other OSes which bundle libdl functions in libc.
* On Windows, filter initial WSAEINVAL warning which occurs
on the initial read attempt of an unbound socket.
* The easy-rsa scripts build-key, build-key-pass, and
build-key-server will now chmod the .key file
to 0600. This is in addition to the fact the generated
keys directory has always been similarly protected
(Pete Harlan).
2005.01.23 -- Version 2.0-rc9
* Fixed error "ROUTE: route addition failed using
CreateIpForwardEntry ..." on Windows when --redirect-gateway
is used over a RRAS internet link.
* When using --route-method exe on Windows, include the
gateway parameter on route delete commands (Mathias Sundman).
* Try not to do a hard reset (i.e. SIGHUP) when two
SIGUSR1 signals are received in close succession.
* If the push list tries to grow beyond its buffer capacity,
the resulting error will be non-fatal.
* To increase the push list capacity (must be done on both
client and server), increase TLS_CHANNEL_BUF_SIZE in
common.h (default=1024).
2005.01.15 -- Version 2.0-rc8
* Fixed bug introduced in rc7 where options error
"--auth-user-pass requires --pull" might occur even
if --pull was correctly specified.
* Changed management interface code to bind once
to TCP socket, rather than rebinding after every
client disconnect.
* Added "disable" directive for client-config-dir
files.
* Windows binary install is now distributed with
OpenSSL 0.9.7e.
* Query the management interface for --http-proxy
username/password if authfile is set to "stdin".
* Added current OpenVPN version number to "Unrecognized
option or missing parameter" error message.
* Added "-extensions server" to "openssl req" command
in easy-rsa/build-key-server (Nir Yeffet).
2005.01.10 -- Version 2.0-rc7
* Fixed bug in management interface which could cause
100% CPU utilization in --proto tcp-server mode
on all *nix OSes except for Linux 2.6.
* --ifconfig-push now accepts DNS names as well as
IP addresses.
* Added sanity check errors when --pull or
--auth-user-pass is used in an incorrect mode.
* Updated man page entries for --client-connect and
--ifconfig-push.
* Added "String Types and Remapping" section to man
page to consisely document the way which OpenVPN
may convert certain types of characters in strings
to ('_').
* Modified bridging description in HOWTO to emphasize
the fact that bridging allows Windows file and print
sharing without a WINS server (Charles Duffy).
2004.12.20 -- Version 2.0-rc6
* Improved checking for epoll support in ./configure
to fix false positive on RH9 (Jan Just Keijser).
* Made the "MULTI TCP: I/O wait required blocking in
multi_tcp_action, action=7" error nonfatal and replaced
with "MULTI: Outgoing TUN queue full, dropped packet".
So far the issue only seems to occur on Linux 2.2
in --mode server --proto tcp mode. It occurs when
the TUN/TAP driver locks up and refuses to accept
new packet writes for a second or more.
* Fixed bug where if a --client-config-dir file tried
to include another file using "config", and if that
include failed, OpenVPN would abort with a fatal
error. Now such inclusion failures will be logged
but are no longer fatal.
* Global changes to the way that packet buffer alignment
is handled. Previously we didn't care about alignment
and took care, when handling 16 and 32 bit words
in buffers, to always use alignment-safe transfers.
This approach appears to be inadequate on some
architectures such as alpha. The new approach is
to initialize packet buffers in a way that anticipates
how component structures will be allocated within
them, to maintain correct alignment.
* Added --dhcp-option DISABLE-NBT to disable NetBIOS
over TCP (Jan Just Keijser).
* Added --http-proxy-option directive for controlling
miscellaneous HTTP proxy options.
* Management state will no longer transition to "WAIT"
during TLS renegotiations.
2004.12.16 -- Version 2.0-rc5
* The --client-config-dir option will now try to open
a default file called "DEFAULT" if no file matching
the common name of the incoming client was found.
* The --client-connect script/plugin can now veto client
authentication by returning a failure code.
* The --learn-address script/plugin can now prevent a
client-instance/address association from being learned
by returning a failure code.
* Changed RPM group in .spec file to Applications/Internet.
2004.12.14 -- Version 2.0-rc4
* SuSE only -- Fixed interaction between openvpn.spec and
suse/openvpn.init where the .spec file was writing the
OpenVPN binary to a different location than where the
.init script was referencing it (Stefan Engel).
* Solaris only -- Split Solaris ifconfig command into two
parts (Jan Just Keijser).
* Some cleanup in add_option().
* Better error checking on input dotted quad IP addresses.
* Verify that --push argument is quoted, if there is
more than one.
* More miscellaneous option sanity checks.
2004.12.13 -- Version 2.0-rc3
* On Windows, when --log or --log-append is used,
save the original stderr for username and password
prompts.
* Fixed a bug introduced in the late 2.0 betas where
if a "verb" parameter >= 16 was used, it would be
ignored and the actual verb level would remain at 1.
* Fixed a bug mostly seen on OS X where --management-hold
or --management-query-passwords would cause the management
interface to be unresponsive to incoming client connections.
* Trigger an options error if one of the management-modifying
options is used without "management" itself.
2004.12.12 -- Version 2.0-rc2
* Amplified warnings in documentation about possible
man-in-the-middle attack when clients do not properly
verify server certificate. Changes to easy-rsa README,
FAQ, HOWTO, man page, and sample client config file.
* Added a warning message if --tls-client or --client
is used without also specifying one of either
--ns-cert-type, --tls-remote, or --tls-verify.
* status_open() fixes for MSVC builds (Blaine Fleming).
* Fix attempt of "ntlm.c:55: error: `des_cblock' undeclared"
compiler error which has been reported on some platforms.
* The openvpn.spec file for rpmbuild has several
new build-time options. See comments in the file.
* Plugins are now built and packaged in the RPM and
will be saved in /usr/share/openvpn/plugin/lib.
* Added --management-hold directive to start OpenVPN
in a hibernating state until released by the
management interface. Also added "hold" command
to the management interface.
2004.12.07 -- Version 2.0-rc1
* openvpn.spec workaround for SuSE confusion regarding
/etc/init.d vs. /etc/rc.d/init.d (Stefan Engel).
2004.12.05 -- Version 2.0-beta20
* The ability to read --askpass and --auth-user-pass
passwords from a file has been disabled by default.
To re-enable, use ./configure --enable-password-save.
* Added additional pre-connected states to management
interface. See management/management-notes.txt
for more info.
* State history is now recorded by the management
interface, and the "state" command now works like
the log or echo commands.
* State history and real-time state change notifications
are now prepended with an integer unix timestamp.
* Added --http-proxy-timeout option, previously
the timeout was hardcoded to 5 seconds.
2004.12.02 -- Version 2.0-beta19
* Fixed bug in management interface line termination
where output lines incorrectly contained a \00 char
after the customary \0d \0a.
* Fixed bug introduced in beta18 where Windows version
would segfault on options errors.
* Fixed bug in management interface where an empty
quoted string ("") entered as a parameter would cause
a segfault.
* Fixed bug where --resolv-retry was not working
properly with multiple --remote hosts.
* Added additional ./configure options to reduce
executable size for embedded applications.
See ./configure --help.
2004.11.28 -- Version 2.0-beta18
* Added management interface. See new --management-*
options or the full management interface documentation
in management/management-notes.txt in the tarball.
Management interface inclusion can be disabled by
./configure --disable-management.
* Added two new plugin modules: auth-pam and down-root.
Auth-pam supports pam-based authentication using a
split privilege execution model, while down-root enables
a down script to be executed with root privileges, even
when --user/--group is used to drop root privileges.
See the plugin directory in the tarball for READMEs,
source code, and Makefiles.
* Plugin developers should note that some changes were
made to the plugin interface since beta17. See
openvpn-plugin.h for details.
Plugin interface inclusion can be disabled with
./configure --disable-plugins
* Added easy-rsa/build-key-server script which will
build a certificate with with nsCertType=server.
* Added --ns-cert-type option for verification
of nsCertType field in peer certificate.
* If --fragment n is specified and --mssfix is specified
without a parameter, default --mssfix to n. This restores
the 1.6 behavior when using --mssfix without a parameter.
* Fixed SSL context initialization bug introduced in beta14
where this error might occur on restarts: "Cannot load
certificate chain ... PEM_read_bio:no start line".
2004.11.11 -- Version 2.0-beta17
* Changed default port number to 1194 per IANA official
port number assignment.
* Added --plugin directive which allows compiled
modules to intercept script callbacks. See
plugin folder in tarball for more info.
* Fixed bug introduced in beta12 where --key-method 1
authentications which should have succeeded would fail.
* Ignore SIGUSR1 during DNS resolution.
* Added SuSE support to openvpn.spec (Umberto Nicoletti).
* Fixed --cryptoapicert SUBJ: parsing bug (Peter 'Luna'
Runestig).
2004.11.07 -- Version 2.0-beta16
* Modified sample-scripts/auth-pam.pl to get username
and password from OpenVPN via a file rather than
via environmental variables.
* Added bytes_sent and bytes_received environmental
variables to be set prior to client-disconnect script.
* Changed client virtual IP derivation precedence:
(1) use --ifconfig-push directive from --client-connect
script, (2) use --ifconfig-push directive from
--client-config-dir, and (3) use --ifconfig-pool
address.
* If a --client-config-dir file specifies --ifconfig-push,
it will be visible to the --client-connect-script in
the ifconfig_pool_remote_ip environmental variable.
* For tun-style tunnels, the ifconfig_pool_local_ip
environmental variable will be set, while for
tap-style tunnels, the ifconfig_pool_netmask variable
will be set.
* Added intelligence to autoconf script to test
compiler for the accepted form of zero-length arrays.
* Fixed a bug introduced in beta12 where --ip-win32
netsh would fail if --dev-node was not explicitly
specified.
* --ip-win32 netsh will now work on hidden adapters.
* Fix attempt of "Assertion failed at crypto.c:149".
This assertion has also been reported on 1.x with a
slightly different line number. The fix is twofold:
(1) In previous releases, --mtu-test may trigger this
assertion -- this bug has been fixed. (2) If something
else causes the assertion to be thrown, don't panic,
just output a nonfatal warning to the log and drop
the packet which generated the error.
* Support TAP interfaces on Mac OS X (Waldemar Brodkorb).
* Added --echo directive.
* Added --auth-nocache directive.
2004.10.28 -- Version 2.0-beta15
* Changed environmental variable character classes
so that names must consist of alphanumeric or
underbar chars and values must consist of printable
characters. Illegal chars will be deleted.
Versions prior to 2.0-beta12 were more restrictive
and would map spaces to '.'.
* On Windows, when the TAP adapter fails to
initialize with the correct IP address, output
"Initialization Sequence Completed with Errors"
to the console or log file.
* Added a warning when user/group/chroot is used
without persist-tun and persist-key.
* Added cryptoapi.[ch] to tarball and source zip.
* --tls-remote option now works with common name
prefixes as well as with the full X509 subject
string. This is a useful alternative to using
a CRL on the client.
* common names associated with a static
--ifconfig-push setting will no longer leave
any state in the --ifconfig-pool-persist file.
* Hard TLS errors (TLS handshake failed) will now
trigger either a SIGUSR1 signal by default
or SIGTERM (if --tls-exit is specified). In TCP
mode, all TLS errors are considered to be hard.
In server mode, the signal will be local to the
client instance.
* Added method parameter to --auth-user-pass-verify
directive to select whether username/password
is passed to script via environment or a temporary
file.
* Added --status-version option to control format
of --status file. The --mode server
--status-version 2 format now includes a line
type token, the virtual IP address is shown
in the client list (even in --dev tap mode),
and the integer time_t value is shown anywhere
an ascii-formatted time/date is also shown.
* Added --remap-usr1 directive which can be used
to control whether internally or externally
generated SIGUSR1 signals are remapped to
SIGHUP (restart without persisting state) or
SIGTERM (exit).
* When running as a Windows service (using
--service option), check the exit event before
and after reading one line of input from
stdin, when reading username/password info.
* For developers: Extended the --gremlin function
to better stress-test the new 2.0 features,
added Valgrind support on Linux and Dmalloc
support on Windows.
2004.10.19 -- Version 2.0-beta14
* Fixed a bug introduced in Beta12 that would occur
if you use a --client-connect script without also
defining --tmp-dir.
* Fixed a bug introduced in Beta12 where a learn-address
script might segfault on the delete method.
* Added Crypto API support in Windows version via
the --cryptoapicert option (Peter 'Luna' Runestig).
2004.10.18 -- Version 2.0-beta13
* Fixed an issue introduced in Beta12 where the private
key password would not be prompted for unless --askpass
was explicitly specified in the config.
2004.10.17 -- Version 2.0-beta12
* Added support for username/password-based authentication.
Clients can now authentication themselves with the server
using either a certificate, a username/password, or both.
New directives: --auth-user-pass, --auth-user-pass-verify,
--client-cert-not-required, and --username-as-common-name.
* Added NTLM proxy patch (William Preston).
* Added --ifconfig-pool-linear server flag to allocate
individual tun addresses for clients rather than /30
subnets (won't work with Windows clients).
* Modified --http-proxy code to cache username/password
across restarts.
* Modified --http-proxy code to read username/password
from the console when the auth file is given as "stdin".
* Modified --askpass to take an optional filename argument.
* --persist-tun and --persist-key now work in client mode
and can be pushed to clients as well.
* Added --ifconfig-pool-persist directive, to maintain
ifconfig-pool info in a file which is persistent across
daemon instantiations.
* --user and --group privilege downgrades as well as
--chroot now also work in client mode (the
dowgrade/chroot will be delayed until the initialization
sequence is completed).
* Added --show-engines standalone directive to show
available OpenSSL crypto accelerator engine support.
* --engine directive now accepts an optional engine-ID
parameter to control which engine is used.
* "Connection reset, restarting" log message now shows
which client is being reset.
* Added --dhcp-pre-release directive in Windows version.
* Second parm to --ip-win32 can be "default", e.g.
--ip-win32 dynamic default 60.
* Fixed documentation bug regarding environmental
variable settings for --ifconfig-pool IP addresses.
The correct environmental variable names are:
ifconfig_pool_local_ip and ifconfig_pool_remote_ip.
* ifconfig_pool_local_ip and ifconfig_pool_remote_ip
environmental variables are now passed to the
client-disconnect script.
* In server mode, environmental variables are now scoped
according to the client they are associated with,
to solve the problem of "crosstalk" between different
client's environmental variable sets.
* Added --down-pre flag to cause --down script to be
called before TUN/TAP close (rather than after).
* Added --tls-exit flag which will cause OpenVPN
to exit on any TLS errors.
* Don't push a route to a client if it exactly
matches an iroute (this lets you push routes to
all clients, and OpenVPN will automatically remove
the route from the route push list only for that client
which the route actually belongs to).
* Made '--resolv-retry infinite' the default.
--resolv-retry can be disabled by using a parameter of 0.
* For clients which plan to pull config info from server,
set an initial default ping-restart of 60 seconds.
* Optimized mute code to lessen the load on the processor
when messages are being muted at a higher frequency.
* Made route log messages non-mutable.
* Silence the Linux "No buffer space available" message.
* Added miscellaneous additional option sanity checks.
* Added Windows version of easy-rsa scripts in
easy-rsa/Windows directory (Andrew J. Richardson).
* Added NetBSD route patch (Ed Ravin).
* Added OpenBSD patch for TAP + --redirect-gateway
(Waldemar Brodkorb).
* Directives which prompt for a username and/or password
will now work with --daemon (OpenVPN will prompt
before forking).
* Warn if CRL is from a different issuer than the
issuer of the peer certificate (Bernhard Weisshuhn).
* Changed init script chkconfig parameters to start
OpenVPN daemon(s) before NFS.
* Bug fix attempt of "too many I/O wait events" which occurs
on OSes which prefer select() over poll() such as Mac OS X.
* Added --ccd-exclusive flag. This flag will require, as a
condition of authentication, that a connecting client has
a --client-config-dir file.
* TAP-Win32 open code will attempt to open a free adapter
if --dev-node is not specified (Mathias Sundman).
* Resequenced --nice and --chroot ordering so that --nice
occurs first.
* Added --suppress-timestamps flag (Charles Duffy).
* Source code changes to allow compilation by MSVC
(Peter 'Luna' Runestig).
* Added experimental --fast-io flag which optimizes
TUN/TAP/UDP writes on non-Windows systems.
2004.08.18 -- Version 2.0-beta11
* Added --server, --server-bridge, --client, and
--keepalive helper directives. See client.conf
and server.conf in sample-config-files for sample
configurations which use the new directives.
* On Windows, added --route-method to control
whether IP Helper API or route.exe is used
to add/delete routes.
* On Windows, added a second parameter to
--route-delay to control the maximum time period
to wait for the TAP-Win32 adapter to come up
before adding routes.
* Fixed bug in Windows version where configurations
which omit --ifconfig might fail to recognize when
the TAP adapter is up.
* Proxy connection failures will now retry according
to the --connect-retry parameter.
* Fixed --dev null handling on Windows so that TLS
loopback test described in INSTALL file works
correctly on Windows.
* Added "Initialization Sequence Completed" message
after all initialization steps have been completed
and the VPN can be considered "up".
* Better sanity-checking on --ifconfig-pool parameters.
* Added --tcp-queue-limit option to control
TUN/TAP -> TCP socket overflow.
* --ifconfig-nowarn flag will now silence general
warnings about possible --ifconfig address
conflicts, including the warning about --ifconfig
and --remote addresses being in same /24 subnet.
* Fixed case where server mode did not correctly
identify certain types of ethernet multicast packets
(Marcel de Kogel).
* Added --explicit-exit-notify option (experimental).
2004.08.02 -- Version 2.0-beta10
* Fixed possible reference after free of option strings
after a restart, bug was introduced in beta8.
* Fixed segfault at route.c:919 in the beta9
Windows version that was being caused by indirection
through a NULL pointer.
* Mistakenly built debug version of TAP-Win32 driver
for beta9. Beta10 has correct release build.
2004.07.30 -- Version 2.0-beta9
* Fixed --route issue on Windows that was introduced with
the new beta8 route implementation based on the
IP Helper API.
2004.07.27 -- Version 2.0-beta8
* Added TCP support in server mode.
* Added PKCS #12 support (Mathias Sundman).
* Added patch to make revoke-crt and make-crl work
seamlessly within the easy-rsa environment (Jan Kiszka).
* Modified --mode server ethernet bridge code to forward
special IEEE 802.1d MAC Groups, i.e. 01:80:C2:XX:XX:XX.
* Added --dhcp-renew and --dhcp-release flags to Windows
version. Normally DHCP renewal and release on the TAP
adapter occurs automatically under Windows, however
if you set the TAP-Win32 adapter Media Status property
to "Always Connected", you may need these flags.
* Added --show-net standalone flag to Windows version to
show OpenVPN's view of the system adapter and routing
tables.
* Added --show-net-up flag to Windows version to output
the system routing table and network adapter list to
the log file after the TAP-Win32 adapter has been brought
up and any routes have been added.
* Modified Windows version to add routes using the IP Helper
API rather than by calling route.exe.
* Fixed bug where --route-up script was not being called
if no --route options were specified.
* Added --mute-replay-warnings to suppress packet replay
warnings. This is a common false alarm on WiFi nets.
* Added "def1" flag to --redirect-gateway option to override
the default gateway by using 0.0.0.0/1 and 128.0.0.0/1
rather than 0.0.0.0/0. This has the benefit of overriding
but not wiping out the original default gateway.
(Thanks to Jim Carter for pointing out this idea).
* You can now run OpenVPN with a single config file argument.
For example, you can now say "openvpn config.conf"
rather than "openvpn --config config.conf".
* On Windows, made --route and --route-delay more adaptive
with respect to waiting for interfaces referenced by the
route destination to come up. Routes added by --route
should now be added as soon as the interface comes up,
rather than after an obligatory 10 second delay. The
way this works internally is that --route-delay now
defaults to 0 on Windows. Previous versions would
wait for --route-delay seconds then add the routes.
This version will wait --route-delay seconds and then
test the routing table at one second intervals for the
next 30 seconds and will not add the routes until they
can be added without errors.
* On Windows, don't setsockopt SO_SNDBUF or SO_RCVBUF by
default on TCP/UDP socket in light of reports that this
action can have undesirable global side effects on the
MTU settings of other adapters. These parameters can
still be set, but you need to explicitly specify
--sndbuf and/or --rcvbuf.
* Added --max-clients option to limit the maximum number
of simultaneously connected clients in server mode.
* Added error message to illuminate shell escape gotcha when
single backslashes are used in Windows path names.
* Added optional netmask parm to --ifconfig-pool.
* Fixed bug where http-proxy connect retry attempts were
incorrectly going to the remote OpenVPN server,
not to the HTTP proxy server.
2004.06.29 -- Version 2.0-beta7
* Fixed bug in link_socket_verify_incoming_addr() which
under certain circumstances could have caused --float
behavior even if --float was not specified.
* --tls-auth option now works with --mode server.
All clients and the server should use the same
--tls-auth key when operating in client/server mode.
* Added --engine option to make use of OpenSSL-supported
crypto acceleration hardware.
* Fixed some high verbosity print format size issues
in event.c for 64 bit platforms (Janne Johansson).
* Made failure to open --log or --log-append file
a non-fatal error.
2004.06.23 -- Version 2.0-beta6
* Fixed Windows installer to intelligently put
up a reboot dialog only if tapinstall tells
us that it's really necessary.
* Fixed "Assertion failed at fragment.c:309"
bug when --mode server and --fragment are used
together.
* Ignore HUP, USR1, and USR2 signals during
initialization. Prior versions would abort.
* Fixed bug on OS X: "Assertion failed at event.c:406".
* Added --service option to Windows version, for use
when OpenVPN is being programmatically instantiated
by another process (see man page for info).
* --log and --log-append options now work on Windows.
* Update OpenBSD INSTALL notes (Janne Johansson).
* Enable multicast on tun interface when running on
OpenBSD (Pavlin Radoslavov).
* Fixed recent --test-crypto breakage, where options
such as --cipher were not being parsed correctly.
* Modified options compatibility string by removing
ifconfig substring if it is empty. Incremented
options compatibility string version number to 4.
* Fixed typo in --tls-timeout option parsing
(Mikael Lonnroth).
2004.06.13 -- Version 2.0-beta5
* Fixed rare --mode server crash that could occur
if data was being routed to a client at
high bandwidth at the precise moment that the
client instance object on the server was being
deleted.
* Fixed issue on machines which have epoll.h and
the epoll_create glibc call defined, but which
don't actually implement epoll in the kernel.
OpenVPN will now gracefully fall back to the
poll API in this case.
* Fixed Windows bug which would cause the following
error in a --mode server --dev tap configuration:
"resource limit WSA_MAXIMUM_WAIT_EVENTS has been
exceeded".
* Added CRL (certificate revocation list) management
scripts to easy-rsa directory (Jon Bendtsen).
* Do a better job of getting the ifconfig component
of the options consistency check to work correctly
when --up-delay is used.
* De-inlined some functions which were too complex
to be inlined anyway with gcc.
* If a --dhcp-option option is pushed to a non-windows
client, the option will be saved in the client's
environment before the --up script is called, under
the name "foreign_option_{n}".
* Added --learn-address script (see man page) which
allows for firewall access through the VPN to be
controlled based on the client common name.
* In mode --server mode, when a client connects to
the server, the server will disconnect any
still-active clients which use the same common
name. Use --duplicate-cn flag to revert to
previous behavior of allowing multiple clients
to concurrently connect with the same common name.
2004.06.08 -- Version 2.0-beta4
* Fixed issue with beta3 where Win32 service wrapper
was keying off of old TAP HWID as a dependency. To
ensure that the new service wrapper is correctly
installed, the Windows install script will uninstall
the old wrapper before installing the new one,
causing a reset of service properties.
* Fixed permissions issue on --status output file,
with default access permissions of owner read/write
only (default permissions can be changed of course with
chmod).
2004.06.05 -- Version 2.0-beta3
* More changes to TAP-Win32 driver's INF file which
affects the placement of the driver in the Windows
device namespace. This is done to work around an
apparent bug in Windows when short HWIDs are used,
and will also ease the upgrade from 1.x to 2.0 by
reducing the chances that a reboot will be needed
on upgrade. Like beta2, this upgrade will
delete existing TAP-Win32 interfaces, and reinstall
a single new interface with default properties.
* Major rewrite of I/O event wait layer in the style
of libevent. This is a precursor to TCP support
in --mode server.
* New feature: --status. Outputs a SIGUSR2-like
status summary to a given file, updated once
per n seconds. The status file is comma delimited
for easy machine parsing.
* --ifconfig-pool now remembers common names and
will try to assign a consistent IP to a given
common name. Still to do: persist --ifconfig-pool
memory across restarts by saving state in file.
* Fixed bug in event timer queue which could cause
recurring timer events such as --ping to not
correctly schedule again after firing. This in
turn would cause spurrious ping restarts and possible
connection outages. Thanks to Denis Vlasenko for
tracking this down.
* Possible fix to reported bug where --daemon argument
was not printing to syslog correctly after restart.
* Fixed bug where pulling --route or --dhcp-option
directives from a server would problematically
interact with --persist-tun on the client.
* Updated contrib/multilevel-init.patch (Farkas Levente).
* Added RPM build option to .spec and .spec.in files
to optionally disable LZO inclusion (Ian Pilcher).
* The latest MingW runtime and headers define
'ssize_t', so a patch is needed (Gisle Vanem).
2004.05.14 -- Version 2.0-beta2
* Fixed signal handling bug in --mode server, where
SIGHUP and SIGUSR1 were treated as SIGTERM.
* Changed the TAP-Win32 HWID from "TAP" to "TAPDEV".
Apparently the larger string may work around
a problem where the TAP adapter is sometimes missing
from the network connections panel, especially under
XP SP2. Also note that installing this upgrade will
uninstall any pre-existing TAP-Win32 adapters, and then
install a single new adapter, meaning that old adapter
properties will be lost. Thanks to Md5Chap for solving
this one.
* For --mode server --dev tap, the options --ifconfig and
--ifconfig-pool are now optional. This allows address
assignment via DHCP or use of a TAP VPN without
IP support, as has always been possible with 1.x.
* Fixed bug where --ifconfig may not work correctly on
Linux 2.2.
* Added 'local' flag to --redirect-gateway for use on
networks where both OpenVPN daemons are connected
to a shared subnet, such as wireless.
2004.05.09 -- Version 2.0-beta1
* Unchanged from test29 except for version number
upgrade.
2004.05.08 -- Version 2.0-test29
* Modified --dev-node on Windows to accept a TAP-Win32
GUID name. In addition, --show-adapters will now
display the high-level name and GUID of each adapter.
This is an attempt to work around an issue in Windows
where sometimes the TAP-Win32 adapter installs correctly
but has no icon in the network connections control
panel. In such cases, being able to specify
--dev-node {TAP-GUID} can work around the missing icon.
2004.05.07 -- Version 2.0-test28
* Fixed bug which could cause segfault on program
shutdown if --route and --persist-tun are used
together.
2004.05.06 -- Version 2.0-test27
* Fixed bug in close_instance() which might cause
memory to be accessed after it had already been freed.
* Fixed bug in verify_callback() that might have
caused uninitialized data to be referenced.
* --iroute now allows full CIDR subnet routing.
* In "--mode server --dev tun" usage, source addresses
on VPN packets coming from a particular client must
be associated with that client in the OpenVPN internal
routing table.
2004.04.28 -- Version 2.0-test26
* Optimized broadcast path in multi-client mode.
* Added socket buffer size options --rcvbuf & --sndbuf.
* Configure Linux tun/tap driver to use a more sensible
txqueuelen default. Also allow explicit setting
via --txqueuelen option (Harald Roelle).
* The --remote option now allows the port number
to be specified as the second parameter. If
unspecified, the port number defaults to the
--rport value.
* Multiple --remote options on the client can now be
specified for load balancing and failover. The
--remote-random flag can be used to initially randomize
the --remote list for basic load balancing.
* If a remote DNS name resolves to multiple DNS addresses,
one will be chosen by random as a kind of basic
load-balancing feature if --remote-random is used.
* Added --connect-freq option to control maximum
new connection frequency in multi-client mode.
* In multi-client mode, all syslog messages associated
with a specific client now include a client-ID prefix.
* For Windows, use a gettimeofday() function based
on QueryPerformanceCounter (Derek Burdick).
* Fixed bug in interaction between --key-method 2
and DES ciphers, where dynamic keys would be generated
with bad parity and then be rejected.
2004.04.17 -- Version 2.0-test24
* Reworked multi-client broadcast handling.
2004.04.13 -- Version 2.0-test23
* Fixed bug in --dev tun --client-to-client routing.
* Fixed a potential deadlock in --pull.
* Fixed a problem with select() usage which could
cause a repeating sequence of "select : Invalid
argument (code=22)"
2004.04.11 -- Version 2.0-test22
* Fixed bug where --mode server + --daemon was
prematurely closing syslog connection.
* Added support for --redirect-gateway on Mac OS X
(Jeremy Apple).
* Minor changes to TAP-Win32 driver based on feedback
from the NDISTest tool.
2004.04.11 -- Version 2.0-test21
* Optimizations in multi-client server event loop.
2004.04.10 -- Version 2.0-test20
* --mode server capability now works with either tun
or tap interfaces. When used with tap interfaces,
OpenVPN will internally bridge all client tap
interfaces with the server tap interface.
* Connecting clients can now have a client-specific
configuration on the server, based on the client
common name embedded in the client certificate.
See --client-config-dir and --client-connect.
These options can be used to configure client-specific
routes.
* Added an option --client-to-client that enables
internal client-to-client routing or bridging.
Otherwise, clients will only "see" the server,
not other connected clients.
* Fixed bug in route scheduling which would have caused
--mode server to not work on Windows in test18
and test19 with the sample config file.
* Man page is up to date with all new options.
* OpenVPN 2.0 release notes on web site updated
with tap-style tunnel examples.
2004.04.02 -- Version 2.0-test19
* Fixed bug where routes pushed from server were
not working correctly on Windows clients.
* Added Mac OS X route patch (Jeremy Apple).
2004.03.30 -- Version 2.0-test18
* Minor fixes + Windows self-install modified
to use OpenSSL 0.9.7d.
2004.03.29 -- Version 2.0-test17
* Fixed some bugs related to instance timeout and deletion.
* Extended --push/--pull option to support additional
option classes.
2004.03.28 -- Version 2.0-test16
* Successful test of --mode udp-server, --push,
--pull, and --ifconfig-pool with server on
Linux 2.4 and clients on Linux and Windows.
2004.03.25 -- Version 2.0-test15
* Implemented hash-table lookup of client instances
based either on remote UDP address/port or remote
ifconfig endpoint.
* Implemented a randomized binary tree based
scheduler for scalably scheduling a large number
of client instance events. Uses the treap
data structure and node rotation algorithm
to keep the tree balanced.
* Initial implementation of ifconfig-pool.
* Made --key-method 2 the default.
2004.03.20 -- Version 2.0-test14
* Implemented --push and --pull.
2004.03.20 -- Version 2.0-test13
* Reduced struct tls_multi and --single-session
memory footprint.
* Modified --single-session flag to be used
in multi-client UDP server client instances.
2004.03.19 -- Version 2.0-test12
* Added the key multi-client UDP server options,
--mode, --push, --pull, and --ifconfig-pool.
* Revamped GC (garbage collection) code to not rely
on any global data.
* Modifications to thread.[ch] to allow a more
flexible thread model.
2004.03.16 -- Version 2.0-test11
* Moved all timer code to interval.h, added new file
interval.c.
* Fixed missing include.
2004.03.16 -- Version 2.0-test10
* More TAP-Win32 fixes.
* Initial debugging and testing of multi.[ch].
2004.03.14 -- Version 2.0-test9
* Branch merge with 1.6-rc3
* More point-to-multipoint work in multi.[ch].
* Major TAP-Win32 driver restructuring to use
NdisMRegisterDevice instead of
IoCreateDevice/IoCreateSymbolicLink.
* Changed TAP-Win32 symbolic links to use \DosDevices\Global\
pathname prefix.
* In the majority of cases, TAP-Win32 should now be
able to install and uninstall on Win2K without requiring
a reboot.
* TAP-Win32 MAC address can now be explicitly set in the
adapter advanced properties page.
2004.03.04 -- Version 2.0-test8
* Branch merge with 1.6-rc2.
2004.03.03 -- Version 2.0-test7
* Branch merge with 1.6-rc1.2.
2004.03.02 -- Version 2.0-test6
* Branch merge with 1.6-rc1.
2004.03.02 -- Version 2.0-test5
* Move Socks5 UDP header append/remove to socks.c, and is
called from forward.c.
* Moved verify statics from ssl.c into struct tls_session.
* Wrote multi.[ch] to handle top level of point-to-multipoint
mode.
* Wrote some code to allow a struct link_socket in a child context
to be slaved to the parent context.
* Broke up packet read and process functions in forward.c
(from socket or tuntap) into separate functions for read
and process, so that point-to-point and point-to-multipoint can
share the same code.
* Expand TLS control channel to allow the passing of configuration
commands.
* Wrote mroute.[ch] to handle internal packet routing for
point-to-multipoint mode.
2004.02.22 -- Version 2.0-test3
* Initial work on UDP multi-client server.
* Branch merge of 1.6-beta7
2004.02.14 -- Version 2.0-test2
* Refactorization of openvpn.c into openvpn.[ch]
init.[ch] forward.[ch] forward-inline.h
occ.[ch] occ-inline.h ping.[ch] ping-inline.h
sig.[ch]. Created a master per-tunnel
struct context in openvpn.h.
* Branch merge of 1.6-beta6.2
2003.11.06 -- Version 2.0-test1
* Initial testbed for 2.0. |
