2005.11.xx -- Version 2.1-beta8
|
|
|
|
* --remap-usr1 will now also remap signals thrown during
|
|
initialization.
|
|
* Added --connect-timeout option to control the timeout
|
|
on TCP client connection attempts (doesn't work on all
|
|
OSes). This patch also makes OpenVPN signalable during
|
|
TCP connection attempts.
|
|
* Fixed bug in acinclude.m4 where capability of compiler
|
|
to handle zero-length arrays in structs is tested
|
|
(David Stipp).
|
|
* Fixed typo in manage.c where inline function declaration
|
|
was declared without the "static" keyword (David Stipp).
|
|
|
|
2005.11.12 -- Version 2.1-beta7
|
|
|
|
* Allow blank passwords to be passed via the management
|
|
interface.
|
|
* Fixed bug where "make check" inside a FreeBSD "jail"
|
|
would never complete (Matthias Andree).
|
|
* Fixed bug where --server directive in --dev tap mode
|
|
claimed that it would support subnets of /30 or less
|
|
but actually would only accept /29 or less.
|
|
* Extend byte counters to 64 bits (M. van Cuijk).
|
|
* PKCS#11 fixes (Alon Bar-Lev).
|
|
|
|
2005.11.02 -- Version 2.0.5
|
|
|
|
* Fixed bug in Linux get_default_gateway function
|
|
introduced in 2.0.4, which would cause redirect-gateway
|
|
on Linux clients to fail.
|
|
* Moved easy-rsa 2.0 scripts to easy-rsa/2.0 to
|
|
be compatible with 2.0.x distribution.
|
|
* Documented --route-nopull.
|
|
* Documented --ip-win32 adaptive.
|
|
* Windows build now linked with LZO2.
|
|
* Allow ca, cert, key, and dh files to be specified
|
|
inline via XML-like syntax without needing to
|
|
reference an explicit file.
|
|
For example:
|
|
<ca>
|
|
data here...
|
|
</ca>
|
|
* Allow plugin and push directives to have multi-line
|
|
parameter lists such as:
|
|
<plugin>
|
|
my-plugin.so
|
|
parm1
|
|
parm2
|
|
</plugin>
|
|
* Added connect-retry-max option (Alon Bar-Lev).
|
|
* Fixed problems where signals thrown during initialization
|
|
were not returning to a management-hold state.
|
|
* Added a backtrack-hardened system time algorithm.
|
|
* Added --remote-cert-ku, --remote-cert-eku, and
|
|
--remote-cert-tls options for verifying certificate
|
|
attributes (Alon Bar-Lev).
|
|
* For Windows, reverted --ip-win32 default back to "dynamic".
|
|
To use new adaptive mode, set explicitly.
|
|
|
|
2005.11.01 -- Version 2.1-beta6
|
|
|
|
* Security fix (merged from 2.0.4) -- Affects non-Windows
|
|
OpenVPN clients of version 2.0 or higher which connect to
|
|
a malicious or compromised server. A format string
|
|
vulnerability in the foreign_option function in options.c
|
|
could potentially allow a malicious or compromised server
|
|
to execute arbitrary code on the client. Only
|
|
non-Windows clients are affected. The vulnerability
|
|
only exists if (a) the client's TLS negotiation with
|
|
the server succeeds, (b) the server is malicious or
|
|
has been compromised such that it is configured to
|
|
push a maliciously crafted options string to the client,
|
|
and (c) the client indicates its willingness to accept
|
|
pushed options from the server by having "pull" or
|
|
"client" in its configuration file (Credit: Vade79).
|
|
CVE-2005-3393
|
|
* Security fix -- (merged from 2.0.4) Potential DoS
|
|
vulnerability on the server in TCP mode. If the TCP
|
|
server accept() call returns an error status, the resulting
|
|
exception handler may attempt to indirect through a NULL
|
|
pointer, causing a segfault. Affects all OpenVPN 2.0 versions.
|
|
CVE-2005-3409
|
|
* Fix attempt of assertion at multi.c:1586 (note that
|
|
this precise line number will vary across different
|
|
versions of OpenVPN).
|
|
* Windows reliability changes:
|
|
(a) Added code to make sure that the local PATH environmental
|
|
variable points to the Windows system32 directory.
|
|
(b) Added new --ip-win32 adaptive mode which tries 'dynamic'
|
|
and then fails over to 'netsh' if the DHCP negotiation fails.
|
|
(c) Made --ip-win32 adaptive the default.
|
|
* More PKCS#11 additions/changes (Alon Bar-Lev).
|
|
* Added ".PHONY: plugin" to Makefile.am to work around
|
|
"make dist" issue.
|
|
* Fixed double fork issue that occurs when --management-hold
|
|
is used.
|
|
* Moved TUN/TAP read/write log messages from --verb 8 to 6.
|
|
* Warn when multiple clients having the same common name or
|
|
username usurp each other when --duplicate-cn is not used.
|
|
* Modified Windows and Linux versions of get_default_gateway
|
|
to return the route with the smallest metric
|
|
if multiple 0.0.0.0/0.0.0.0 entries are present.
|
|
* Added ">NEED-OK" alert and "needok" command to management
|
|
interface to provide a general interface for sending
|
|
alerts to the end-user. Used by the PKCS#11 code
|
|
to send Token Insertion Requests to the user.
|
|
* Added actual remote address used to the ">STATE" alert
|
|
in the management interface (Rolf Fokkens).
|
|
|
|
2005.10.17 -- Version 2.1-beta4
|
|
|
|
* Fixed bug introduced in 2.1-beta3 where management
|
|
socket bind would fail.
|
|
* --capath fix in ssl.c (Zhuang Yuyao).
|
|
* Added ".PHONY: plugin" to Makefile.am, reverted
|
|
location of "plugin" directory (thanks to
|
|
Matthias Andree for figuring this out).
|
|
|
|
2005.10.16 -- Version 2.1-beta3
|
|
|
|
* Added PKCS#11 support (Alon Bar-Lev).
|
|
* Enable the use of --ca together with --pkcs12. If --ca is
|
|
used at the same time as --pkcs12, the CA certificate is loaded
|
|
from the file specified by --ca regardless if the pkcs12 file
|
|
contains a CA cert or not (Mathias Sundman).
|
|
* Merged --capath patch (Thomas Noel).
|
|
* Merged --multihome patch.
|
|
* Added --bind option for TCP client connections (Ewan Bhamrah
|
|
Harley).
|
|
* Moved "plugin" directory to "plugins" to deal with strange
|
|
automake problem that ended up being also fixable with
|
|
".PHONY: plugin" in Makefile.am.
|
|
|
|
2005.10.13 -- Version 2.1-beta2
|
|
|
|
* Made --sndbuf and --rcvbuf pushable.
|
|
|
|
2005.10.01 -- Version 2.1-beta1
|
|
|
|
* Made LZO setting pushable.
|
|
* Renamed sample-keys/tmp-ca.crt to ca.crt.
|
|
* Fixed bug where remove_iroutes_from_push_route_list
|
|
was missing routes if those routes had
|
|
an implied netmask (by omission) of 255.255.255.255.
|
|
* Merged with 2.0.3-rc1
|
|
* easy-rsa/2.0 moved to easy-rsa
|
|
* old easy-rsa moved to easy-rsa/1.0
|
|
|
|
2005.09.23 -- Version 2.0.2-TO4
|
|
|
|
* Added feature to TAP-Win32 adapter to allow it to be
|
|
opened from non-administrator mode. This feature
|
|
is enabled by default, and can be enabled/disabled
|
|
in the adapter advanced properties dialog.
|
|
* Added --allow-nonadmin standalone option for Windows to
|
|
set TAP adapter to allow non-admin access. This
|
|
is a user-mode version of the code, and duplicates
|
|
the same feature as the above entry.
|
|
* Added fix that attempts to solve corner case of tunnel not
|
|
forwarding packets when system clock is reset to an earlier time.
|
|
* Added --redirect-gateway bypass-dns option. (Developers:
|
|
To add bypass-dhcp or bypass-dns support to other OSes,
|
|
add a get_bypass_addresses function to route.c for
|
|
your OS.)
|
|
* Added OPENVPN_PLUGIN_CLIENT_CONNECT_V2 plugin callback, which
|
|
allows a client-connect plugin to return configuration text
|
|
in memory, rather than via a file.
|
|
* Fixed a bug where --mode server --proto tcp-server --cipher none
|
|
operation could cause tunnel packet truncation.
|
|
* openvpn --version will show [LZO1] or [LZO2], depending on
|
|
version that was linked.
|
|
|
|
2005.09.07 -- Version 2.0.2-TO1
|
|
|
|
* Added --topology directive. See man page.
|
|
* Added --redirect-gateway bypass-dhcp option to add a route
|
|
allowing DHCP packets to bypass the tunnel, when the
|
|
DHCP server is non-local. Currently only implemented
|
|
on Windows clients.
|
|
* Modified OpenVPN Service on Windows to declare the DHCP
|
|
client service as a dependency.
|
|
* Extended the plugin interface to allow plugins to declare
|
|
per-client constructor and destructor functions, to make
|
|
it simpler for plugins to maintain per-client state.
|
|
|
|
2005.09.25 -- Version 2.0.3-rc1
|
|
|
|
* openvpn_plugin_abort_v1 function wasn't being properly
|
|
registered on Windows.
|
|
* Fixed a bug where --mode server --proto tcp-server --cipher none
|
|
operation could cause tunnel packet truncation.
|
|
|
|
2005.08.25 -- Version 2.0.2
|
|
|
|
* No change from 2.0.2-rc1.
|
|
|
|
2005.08.24 -- Version 2.0.2-rc1
|
|
|
|
* Fixed regression bug in Win32 installer, introduced in 2.0.1,
|
|
which incorrectly set OpenVPN service to autostart.
|
|
* Don't package source code zip file in Windows installer
|
|
in order to reduce the size of the installer. The source
|
|
zip file can always be downloaded separately if needed.
|
|
* Fixed bug in route.c in FreeBSD, Darwin, OpenBSD and NetBSD
|
|
version of get_default_gateway. Allocated socket for route
|
|
manipulation is never freed so number of mbufs continuously
|
|
grow and exhaust system resources after a while (Jaroslav Klaus).
|
|
* Fixed bug where "--proto tcp-server --mode p2p --management
|
|
host port" would cause the management port to not respond until
|
|
the OpenVPN peer connects.
|
|
* Modified pkitool script to be /bin/sh compatible (Johnny Lam).
|
|
|
|
2005.08.16 -- Version 2.0.1
|
|
|
|
* Security Fix -- DoS attack against server when run with "verb 0" and
|
|
without "tls-auth". If a client connection to the server fails
|
|
certificate verification, the OpenSSL error queue is not properly
|
|
flushed, which can result in another unrelated client instance on the
|
|
server seeing the error and responding to it, resulting in disconnection
|
|
of the unrelated client (CAN-2005-2531).
|
|
* Security Fix -- DoS attack against server by authenticated client.
|
|
This bug presents a potential DoS attack vector against the server
|
|
which can only be initiated by a connected and authenticated client.
|
|
If the client sends a packet which fails to decrypt on the server,
|
|
the OpenSSL error queue is not properly flushed, which can result in
|
|
another unrelated client instance on the server seeing the error and
|
|
responding to it, resulting in disconnection of the unrelated client
|
|
(CAN-2005-2532).
|
|
* Security Fix -- DoS attack against server by authenticated client.
|
|
A malicious client in "dev tap" ethernet bridging mode could
|
|
theoretically flood the server with packets appearing to come from
|
|
hundreds of thousands of different MAC addresses, causing the OpenVPN
|
|
process to deplete system virtual memory as it expands its internal
|
|
routing table. A --max-routes-per-client directive has been added
|
|
(default=256) to limit the maximum number of routes in OpenVPN's
|
|
internal routing table which can be associated with a given client
|
|
(CAN-2005-2533).
|
|
* Security Fix -- DoS attack against server by authenticated client.
|
|
If two or more client machines try to connect to the server at the
|
|
same time via TCP, using the same client certificate, and when
|
|
--duplicate-cn is not enabled on the server, a race condition can
|
|
crash the server with "Assertion failed at mtcp.c:411"
|
|
(CAN-2005-2534).
|
|
* Fixed server bug where under certain circumstances, the client instance
|
|
object deletion function would try to delete iroutes which had never been
|
|
added in the first place, triggering "Assertion failed at mroute.c:349".
|
|
* Added --auth-retry option to prevent auth errors from being fatal
|
|
on the client side, and to permit username/password requeries in case
|
|
of error. Also controllable via new "auth-retry" management interface
|
|
command. See man page for more info.
|
|
* Added easy-rsa 2.0 scripts to the tarball in easy-rsa/2.0
|
|
* Fixed bug in openvpn.spec where rpmbuild --define 'without_pam 1'
|
|
would fail to build.
|
|
* Implement "make check" to perform loopback tests (Matthias Andree).
|
|
|
|
2005.07.21 -- Version 2.0.1-rc7
|
|
|
|
* Support LZO 2.01 which renamed its library to lzo2 (Matthias Andree).
|
|
* Include linux/types.h before checking for linux/errqueue.h (Matthias
|
|
Andree).
|
|
|
|
2005.07.15 -- Version 2.0.1-rc6
|
|
|
|
* Commented out "user nobody" and "group nobody" in sample
|
|
client/server config files.
|
|
* Allow '@' character to be used in --client-config-dir
|
|
file names.
|
|
|
|
2005.07.04 -- Version 2.0.1-rc5
|
|
|
|
* Windows version will log a for-further-info URL when
|
|
initialization sequence is completed with errors.
|
|
* Added DLOPEN_PAM parameter to plugin/auth-pam/Makefile
|
|
to control whether auth-pam plugin links to PAM via
|
|
dlopen or -lpam. By default, DLOPEN_PAM=1 so pre-existing
|
|
behavior should be preserved. DLOPEN_PAM=0 is the preferred
|
|
setting to link via -lpam, but DLOPEN_PAM=1 works around
|
|
a bug in SuSE 9.1 (and possibly other distros as well)
|
|
where the PAM modules are not linked with -lpam. See
|
|
thread on openvpn-devel for more discussion about this
|
|
patch (Simon Perreault).
|
|
|
|
2005.06.15 -- Version 2.0.1-rc4
|
|
|
|
* Support LZO 2.00, including changes to configure script to
|
|
autodetect LZO version.
|
|
|
|
2005.06.12 -- Version 2.0.1-rc3
|
|
|
|
* Fixed a bug which caused standard file handles to not be closed
|
|
after daemonization when --plugin and --daemon are used together,
|
|
and if the plugin initialization function forks (as does auth-pam
|
|
and down-root) (Simon Perreault).
|
|
* Added client-side up/down scripts in contrib/pull-resolv-conf
|
|
for accepting server-pushed "dhcp-option DOMAIN" and "dhcp-option DNS"
|
|
on Linux/Unix systems (Jesse Adelman).
|
|
* Fixed bug where if client-connect scripts/plugins were cascaded,
|
|
and one (but not all) of them returned an error status, there might
|
|
be cases where for an individual script/plugin, client-connect was
|
|
called but not client-disconnect. The goal of this fix is to
|
|
ensure that if client-connect is called on a given client instance,
|
|
then client-disconnect will definitely be called. A potential
|
|
complication of this fix is that when client-connect functions are
|
|
cascaded, it's possible that the client-disconnect function would
|
|
be called in cases where the related client-connect function returned
|
|
an error status. This fix should not alter OpenVPN behavior when
|
|
scripts/plugins are not cascaded.
|
|
* Changed the hard-to-reproduce "Assertion failed at fragment.c:312"
|
|
fatal error to a warning: "FRAG: outgoing buffer is not empty".
|
|
Need more info on how to reproduce this one.
|
|
* When --duplicate-cn is used, the --ifconfig-pool allocation
|
|
algorithm will now allocate the first available IP address.
|
|
* When --daemon and --management-hold are used together,
|
|
OpenVPN will daemonize before it enters the management hold state.
|
|
|
|
2005.05.16 -- Version 2.0.1-rc2
|
|
|
|
* Modified vendor test in openvpn.spec file to match against
|
|
"Mandrakesoft" in addition to "MandrakeSoft".
|
|
* Using --iroute in a --client-config-dir file while in --dev tap
|
|
mode is not currently supported and will produce a warning
|
|
message. Fixed bug where in certain cases, in addition to
|
|
generating a warning message, this combination of options
|
|
would also produce a fatal assertion in mroute.c.
|
|
* Pass --auth-user-pass username to server-side plugin without
|
|
performing any string remapping (plugins, unlike scripts,
|
|
don't get any security benefit from string remapping).
|
|
This is intended to fix an issue with openvpn-auth-pam/pam_winbind
|
|
where backslash characters in a username ('\') were being remapped
|
|
to underscore ('_').
|
|
* Updated OpenSSL DLLs in Windows build to 0.9.7g.
|
|
* Documented --explicit-exit-notify in man page.
|
|
* --explicit-exit-notify seconds parameter defaults to 1 if
|
|
unspecified.
|
|
|
|
2005.04.30 -- Version 2.0.1-rc1
|
|
|
|
* Fixed bug where certain kinds of fatal errors after
|
|
initialization (such as port in use) would leave plugin
|
|
processes (such as openvpn-auth-pam) still running.
|
|
* Added optional openvpn_plugin_abort_v1 plugin function for
|
|
closing initialized plugin objects in the event of a fatal
|
|
error by main OpenVPN process.
|
|
* When the --remote list is > 1, and --resolv-retry is not
|
|
specified (meaning that it defaults to "infinite"), apply the
|
|
infinite timeout to the --remote list as a whole, but try each
|
|
list item only once before moving on to the next item.
|
|
* Added new --syslog directive which redirects output
|
|
to syslog without requiring the use of the --daemon or --inetd
|
|
directives.
|
|
* Added openvpn.spec option to allow RPM to be built with support
|
|
for passwords read from a file:
|
|
rpmbuild -tb [openvpn.x.tar.gz] --define 'with_password_save 1'
|
|
|
|
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).
|

|
|
|
|
|
|
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.

|
|
init.[ch] forward.[ch] forward-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.
|
|
|
|
2004.05.09 -- Version 1.6.0
|
|
|
|
* Unchanged from 1.6-rc4 except for version number
|
|
upgrade.
|
|
|
|
2004.04.01 -- Version 1.6-rc4
|
|
|
|
* Made minor customizations to devcon and
|
|
renamed as tapinstall.exe for Windows version.
|
|
* Fixed "storage size of `iv' isn't known" build
|
|
problem on FreeBSD.
|
|
* OpenSSL 0.9.7d bundled with Windows self-install.
|
|
|
|
2004.03.13 -- Version 1.6-rc3
|
|
|
|
* Minor Windows fixes for --ip-win32 dynamic, relating to
|
|
the way the TAP-Win32 driver responds to a DHCP request
|
|
from the Windows DHCP client.
|
|
* The net_gateway environmental variable wasn't being
|
|
set correctly for called scripts (Paul Zuber).
|
|
* Added code to determine the default gateway on FreeBSD,
|
|
allowing the --redirect-gateway option to work
|
|
(Juan Rodriguez Hervella).
|
|
|
|
2004.03.04 -- Version 1.6-rc2
|
|
|
|
* Fixed bug in Windows version where the NetBIOS node-type
|
|
DHCP option might have been passed even if it was not
|
|
specified.
|
|
* Fixed bug in Windows version introduced in 1.6-rc1, where
|
|
DHCP timeout would be set to 0 seconds if --ifconfig option
|
|
was used and --ip-win32 option was not explicitly specified.
|
|
* Added some new --dhcp-option types for Windows version.
|
|
|
|
2004.03.02 -- Version 1.6-rc1
|
|
|
|
* For Windows, make "--ip-win32 dynamic" the default.
|
|
* For Windows, make "--route-delay 10" the default
|
|
unless --ip-win32 dynamic is not used or --route-delay
|
|
is explicitly specified.
|
|
* L_TLS mutex could have been left in a locked state
|
|
for certain kinds of TLS errors.
|
|
|
|
2004.02.22 -- Version 1.6-beta7
|
|
|
|
* Allow scheduling priority increase (--nice) together
|
|
with UID/GID downgrade (--user/--group).
|
|
* Code that causes SIGUSR1 restart on TLS errors in TCP
|
|
mode was not activated in pthread builds.
|
|
* Save the certificate serial number in an environmental
|
|
variable called tls_serial_{n} prior to calling the
|
|
--tls-verify script. n is the current cert chain level.
|
|
* Added NetBSD IPv6 tunnel capability (also requires
|
|
a kernel patch) (Horst Laschinsky).
|
|
* Fixed bug in checking the return value of the nice()
|
|
function (Ian Pilcher).
|
|
* Bug fix in new FreeBSD IPv6 over TUN code which was
|
|
originally added in 1.6-beta5 (Nathanael Rensen).
|
|
* More Socks5 fixes -- extended the struct frame
|
|
infrastructure to accomodate proxy-based encapsulation
|
|
overhead.
|
|
* Added --dhcp-option to Windows version for setting
|
|
adapter properties such as WINS & DNS servers.
|
|
* Use a default route-delay of 5 seconds when
|
|
--ip-win32 dynamic is specified (only applicable when
|
|
--route-delay is not explicitly specified).
|
|
* Added "log_append" registry variable to control
|
|
whether the OpenVPN service wrapper on Windows
|
|
opens log files in append (log_append="1") or
|
|
truncate (log_append="0") mode. The default
|
|
is truncate.
|
|
|
|
2004.02.05 -- Version 1.6-beta6
|
|
|
|
* UDP over Socks5 fix to accomodate Socks5 encapsulation
|
|
overhead (Christof Meerwald).
|
|
* Minor --ip-win32 dynamic tweaks (use long lease time,
|
|
invalidate existing lease with DHCPNAK).
|
|
|
|
2004.02.01 -- Version 1.6-beta5
|
|
|
|
* Added Socks5 proxy support (Christof Meerwald).
|
|
* IPv6 tun support for FreeBSD (Thomas Glanzmann).
|
|
* Special TAP-Win32 debug mode for Windows self-install that was
|
|
enabled in beta4 is now turned off.
|
|
* Added some new Solaris notes to INSTALL (Koen Maris).
|
|
* More work on --ip-win32 dynamic.
|
|
|
|
2004.01.27 -- Version 1.6-beta4
|
|
|
|
* For this beta, the Windows self-install is a debug version
|
|
and will run slower -- use only for testing.
|
|
* Reverted the --ip-win32 default back to 'ipapi'
|
|
from 'dynamic'.
|
|
* Added the offset parameter to '--ip-win32 dynamic' which
|
|
can be used to control the address of the masqueraded
|
|
DHCP server which replies to Windows DHCP requests.
|
|
* Added a wait/nowait option to --inetd (nowait can only
|
|
be used with TCP sockets, TLS authentication, and over
|
|
a bridged configuration -- see FAQ for more info)
|
|
(Stefan `Sec` Zehl).
|
|
* Added a build-time capability where TAP-Win32 driver
|
|
debug messages can be output by OpenVPN at --verb 6
|
|
or higher.
|
|
|
|
2004.01.20 -- Version 1.6-beta2
|
|
|
|
* Added ./configure --enable-iproute2 flag which
|
|
uses iproute2 instead of route + ifconfig --
|
|
this is necessary for the LEAF Linux distro
|
|
(Martin Hejl).
|
|
* Added renewal-time and rebind-time to set of
|
|
DHCP options returned by the TAP-Win32 driver when
|
|
"--ip-win32 dynamic" is used.
|
|
|
|
2004.01.14 -- Version 1.6-beta1
|
|
|
|
* Fixed --proxy bug that sometimes caused plaintext
|
|
control info generated by the proxy prior to http
|
|
CONNECT method establishment to be incorrectly
|
|
parsed as OpenVPN data.
|
|
* For Windows version, implemented the
|
|
"--ip-win32 dynamic" method and made it the default.
|
|
This method sets the TAP-Win32 adapter IP address
|
|
and netmask by replying to the kernel's DHCP queries.
|
|
See the man page for more detailed info.
|
|
* Added --connect-retry parameter which controls
|
|
the time interval (in seconds) between connect()
|
|
retries when --proto tcp-client is used. Previously,
|
|
this value was hardcoded to 5 seconds, and still
|
|
defaults as such.
|
|
* --resolv-retry can now be used with a parameter
|
|
of "infinite" to retry indefinitely.
|
|
* Added SSL_CTX_use_certificate_chain_file() to ssl.c
|
|
for support of multi-level certificate chains
|
|
(Sten Kalenda).
|
|
* Fixed --tls-auth incompatibility with 1.4.x and earlier
|
|
versions of OpenVPN when the passphrase file is an
|
|
OpenVPN static key file (as generated by --genkey).
|
|
* Added shell-escape support in config files using
|
|
the backslash character ("\") so that (for example)
|
|
double quotes can be passed to the shell.
|
|
* Added "contrib" subdirectory on tarball, source zip,
|
|
and CVS containing user-submitted contributions.
|
|
* Added an optional patch to the Redhat init script to
|
|
allow the configuration file directory to be a
|
|
multi-level directory hierarchy (Farkas Levente).
|
|
See contrib/multilevel-init.patch
|
|
* Added some scripts and documentation on using
|
|
Linux "fwmark" iptables rules to enable
|
|
fine-grained routing control over the VPN
|
|
(Sean Reifschneider, <jafo@tummy.com>).
|
|
See contrib/openvpn-fwmarkroute-1.00
|
|
|
|
2003.11.20 -- Version 1.5.0
|
|
|
|
* Minor documentation changes.
|
|
|
|
2003.11.04 -- Version 1.5-beta14
|
|
|
|
* Fixed build problem with ./configure --disable-ssl
|
|
that was reported on Debian woody.
|
|
* Fixed bug where --redirect-gateway could not be used
|
|
together with --resolv-retry.
|
|
|
|
2003.11.03 -- Version 1.5-beta13
|
|
|
|
* Added CRL (certificate revocation list) capability using
|
|
--crl-verify option (Stefano Bracalenti).
|
|
* Added --replay-window option for variable replay-protection
|
|
window sizes.
|
|
* Fixed --fragment bug which might have caused certain large
|
|
packets to be sent unfragmented.
|
|
* Modified --secret and --tls-auth to permit different cipher and
|
|
HMAC keys to be used for each data flow direction. Also
|
|
increased static key file size generated by --genkey from
|
|
1024 to 2048 bits, where 512 bits each are reserved for
|
|
send-HMAC, encrypt, receive-HMAC, and decrypt. Key file forward
|
|
and backward compatibility is maintained. See --secret option
|
|
documentation on the man page for more info.
|
|
* Added --tls-remote option (Teemu Kiviniemi).
|
|
* Fixed --tls-cipher documention regarding correct delimiter
|
|
usage (Teemu Kiviniemi).
|
|
* Added --key-method option for selecting alternative data
|
|
channel key negotiation methods. Method 1 is the default.
|
|
Method 2 has been added (see man page for more info).
|
|
* Added French translation of HOWTO to web site
|
|
(Guillaume Lehmann).
|
|
* Fixed problem caused by late resolver library load on
|
|
certain platforms when --resolv-retry and --chroot are
|
|
used together (Teemu Kiviniemi).
|
|
* In TCP mode, all decryption or TLS errors will abort the current
|
|
connection (this is not done in UDP mode because UDP is
|
|
"connectionless").
|
|
* Fixed a TCP client reconnect bug that only occurs on the
|
|
BSDs, where connect() fails with an invalid argument. This
|
|
bug was partially (but not completely) fixed in beta7.
|
|
* Added "route_net_gateway" environmental variable which contains
|
|
the pre-existing default gateway address from the routing table
|
|
(there's no standard API for getting the default gateway, so
|
|
right now this feature only works on Windows or Linux).
|
|
* Renamed the "route_default_gateway" enviromental variable to
|
|
"route_vpn_gateway" -- this is the remote VPN endpoint.
|
|
* The special keywords vpn_gateway, net_gateway, and remote_host
|
|
can now be used for the network or gateway components of the
|
|
--route option. See the man page for more info.
|
|
* Added the --redirect-gateway option to configure the VPN
|
|
as the default gateway (implemented on Linux and Windows only).
|
|
* Added the --http-proxy option with basic authentication
|
|
support for use in TCP client mode. Successfully tested
|
|
using Squid as the HTTP proxy, with and without authentication.
|
|
|
|
2003.10.12 -- Version 1.5-beta12
|
|
|
|
* Fixed Linux-only bug in --mktun and --rmtun which was
|
|
introduced around beta8 or so, which would cause
|
|
an error such as "I don't recognize device tun0 as a
|
|
tun or tap device1".
|
|
* Added --ifconfig-nowarn option to disable options
|
|
consistency warnings about --ifconfig parameters.
|
|
* Don't allow any kind of sequence number backtracking or
|
|
message reordering when in TCP mode.
|
|
* Changed beta naming convention to use '_' (underscore)
|
|
rather than '-' (dash) to pacify rpmbuild.
|
|
|
|
2003.10.08 -- Version 1.5-beta11
|
|
|
|
* Modified code in the Windows version which sets the IP address
|
|
and netmask of the TAP-Win32 adapter using the IP Helper API.
|
|
Most of the changes involve better error recovery when
|
|
the IP Helper API returns an error status. See the
|
|
manual page entry on --ip-win32 for more info.
|
|
|
|
2003.10.08 -- Version 1.5-beta10
|
|
|
|
* Added getpass() function for Windows version so that --askpass
|
|
option works correctly (Stefano Bracalenti).
|
|
* Added reboot advisory to end of Win32 install script.
|
|
* Changed crypto code to use pseudo-random IVs rather than
|
|
carrying forward the IV state from the previous packet.
|
|
This is in response to item 2 in the following document:
|
|
http://www.openssl.org/~bodo/tls-cbc.txt which points
|
|
out weaknesses in TLS's use of the same IV carryforward
|
|
approach. This change does not break protocol compatibility
|
|
with previous versions of OpenVPN.
|
|
* Made a change to the crypto replay protection code to also
|
|
protect against certain kinds of packet reordering attacks.
|
|
This change does not break protocol compatibility with
|
|
previous versions of OpenVPN.
|
|
* Added --ip-win32 option to provide several choices for
|
|
setting the IP address on the TAP-Win32 adapter.
|
|
* #ifdefed out non-CBC crypto modes by default.
|
|
* Added --up-delay option to delay TUN/TAP open and --up script
|
|
execution until after connection establishment. This option
|
|
replaces the earlier windows-only option --tap-delay.
|
|
|
|
2003.10.01 -- Version 1.5-beta9
|
|
|
|
* Fixed --route-noexec bug where option was not parsed correctly.
|
|
* Complain if --dev tun is specified without --ifconfig on Windows.
|
|
* Fixed bug where TCP connections on windows would sometimes cause
|
|
an assertion failure.
|
|
* Added a new flag to TAP-Win32 advanced properties that allows one
|
|
to set the adapter to be always "connected" even when an OpenVPN
|
|
process doesn't have it open. The default behavior is to report
|
|
a media status of connected only when an OpenVPN process has the
|
|
adapter open.
|
|
* Rebuilt the Windows self-install distribution with OpenSSL 0.9.7c
|
|
DLLs in response to an OpenSSL security advisory.
|
|
|
|
2003.09.30 -- Version 1.5-beta8
|
|
|
|
* Extended the --ifconfig option to work on tap devices as well
|
|
as tun devices.
|
|
* Implemented the --ifconfig option for Windows, by calling the
|
|
netsh tool.
|
|
* By default, do an "arp -d *" on Windows after TAP-Win32 open to
|
|
refresh the MAC cache. This behaviour can be disabled with
|
|
--no-arp-del.
|
|
* On Windows, allow the --dev-node parameter (which specifies
|
|
the name of the TAP-Win32 adapter) to be omitted in cases where
|
|
there is a single TAP-Win32 adapter on the system which can be
|
|
assumed to be the default.
|
|
* Modified the diagnostic --verb 5 debugging level to print 'R'
|
|
for TCP/UDP read, 'W' for TCP/UDP write, 'r' for TUN/TAP read,
|
|
and 'w' for TUN/TAP write.
|
|
* Conditionalize OpenBSD read_tun and write_tun based on tun or tap
|
|
mode.
|
|
* Added IPv6 tun support to OpenBSD (Thomas Glanzmann).
|
|
* Make the --enable-mtu-dynamic ./configure option enabled by
|
|
default.
|
|
* Deprecated the --mtu-dynamic run-time option, in favor of
|
|
--fragment.
|
|
* DNS names can now be used as --ifconfig parameters.
|
|
* Significant work on TAP-Win32 driver to bring up to SMP standards.
|
|
* On Windows, fixed dangling IRP problem if TAP-Win32 driver is
|
|
unloaded or disabled, while a user-space process has it open.
|
|
* On Windows, if --tun-mtu is not specified, it will be read from
|
|
the TAP-Win32 driver via ioctl.
|
|
* On Windows, added TAP-Win32 driver status info to "F2" keyboard
|
|
signal (only when run from a console window).
|
|
* Added --mssfix option to control TCP MSS size (YANO Hirokuni).
|
|
* Renamed --mtu-dynamic option to --fragment to more accurately
|
|
reflect its function. Fragment accepts a single parameter which
|
|
is the upper limit on acceptable UDP packet size.
|
|
* Changed default --tun-mtu-extra parameter to 32 from 64.
|
|
* Eliminated reference to malloc.o in configure.ac.
|
|
* Added tun device emulation to the TAP-Win32 driver.
|
|
* Added --route and related options.
|
|
* Added init script for SuSE Linux (Frank Plohmann).
|
|
* Extended option consistency check between peers to function
|
|
in all crypto modes, including static-key and cleartext modes.
|
|
Previously only TLS mode was supported. Disable with
|
|
--disable-occ.
|
|
* Overall, increased the amount of configuration option sanity
|
|
checking, especially of networking parameters.
|
|
* Added --mtu-test option for empirical MTU measurement.
|
|
* Added Windows-only option --tap-delay to not set the TAP-Win32
|
|
adapter media state to 'connected' until TCP/UDP connection
|
|
establishment with peer.
|
|
* Slightly modified --route/--route-delay semantics so that when
|
|
--route is given without --route-delay, routes are added
|
|
immediately after tun/tap device open. When --route-delay is
|
|
specified, routes will be added n seconds after connection
|
|
initiation, where n is the --route-delay parameter (which
|
|
can be set to 0).
|
|
* Made TCP framing error into a non-fatal error that triggers a
|
|
connection reset.
|
|
|
|
2003.08.28 -- Version 1.5-beta7
|
|
|
|
* Fixed bug that caused OpenVPN not to respond to exit/restart
|
|
signals when --resolv-retry is used and a local or remote DNS
|
|
name cannot be resolved.
|
|
* Exported a series of environmental variables with useful
|
|
info for scripts. See man page for more info. Based
|
|
on a suggestion by Anthony Ciaravalo.
|
|
* Moved TCP/UDP socket bind to a point in the initialization
|
|
before the --up script gets called. This is desirable
|
|
because (a) a socket bind failure will happen before
|
|
daemonization, allowing an error status code to be returned
|
|
to the shell and (b) the possibility is eliminated of a
|
|
socket bind failure causing the --up script to be run
|
|
but not the --down script. This change has a side effect
|
|
that --resolv-retry will no longer work with --local.
|
|
* Fixed bug where if an OpenVPN TCP server went down and back
|
|
up again, Solaris or FreeBSD clients would fail to reconnect
|
|
to it.
|
|
* Fixed bug that prevented OpenVPN from being run by
|
|
inetd/xinetd in TCP mode.
|
|
* Added --log and --log-append options for logging messages to
|
|
a file.
|
|
* On Windows, check that the current user is a member of the
|
|
Administrator group before attempting install or uninstall.
|
|
|
|
2003.08.16 -- Version 1.5-beta6
|
|
|
|
* Fixed TAP-Win32 driver to properly increment the Rx/Tx count.
|
|
|
|
2003.08.14 -- Version 1.5-beta5
|
|
|
|
* Added user-configurability of the TAP-Win32 adapter MTU
|
|
through the adapter advanced properties page.
|
|
* Added Windows Service support.
|
|
* On Windows, added file association and right-clickability
|
|
for .ovpn files (OpenVPN config files).
|
|
|
|
2003.08.05 -- Version 1.5-beta4
|
|
|
|
* Extra refinements and error checking added to Windows
|
|
NSIS install script.
|
|
|
|
2003.08.05 -- Version 1.5-beta3
|
|
|
|
* Added md5.h include to crypto.c to fix build problem on
|
|
OpenBSD.
|
|
* Created a Win32 installer using NSIS.
|
|
* Removed DelService command from TAP-Win32 INF file. It appears
|
|
to be not necessary and it interfered with the ability to
|
|
uninstall and reinstall the driver without needing to reboot.
|
|
* On Windows version, added "addtap" and "deltapall" batch
|
|
files to add and delete TAP-Win32 adapter instances.
|
|
|
|
2003.07.31 -- Version 1.5-beta2
|
|
|
|
* Renamed INSTALL.w32 to INSTALL-win32.txt and reformatted
|
|
in Windows ASCII so it's easier to click and view.
|
|
* Added postscript and PDF versions of the HOWTO to the web
|
|
site (C R Zamana).
|
|
* Merged Michael Clarke's stability patch into TAP-Win32
|
|
driver which appears to fix the suspend/resume driver bug
|
|
and significantly improve driver stability.
|
|
* Added Christof Meerwald's Media Status patch to the
|
|
TAP-Win32 driver which shows the TAP adapter to be
|
|
disconnected when OpenVPN is not running.
|
|
* Moved socket connect and TCP server listen code to a later
|
|
point in openvpn() function so that the TCP server listen
|
|
state is entered after daemonization.
|
|
* Added keyboard shortcuts to simulate signals in the Windows
|
|
version, see the window title bar for descriptions.
|
|
|
|
2003.07.24 -- Version 1.5-beta1
|
|
|
|
* Added TCP support via the new --proto option.
|
|
* Renamed udp-centric options such as --udp-mtu to
|
|
--link-mtu (old option names preserved for compatibility).
|
|
* Ported to Windows 2000 + XP using mingw and a TAP driver
|
|
derived from the Cipe-Win32 project by Damion K. Wilson.
|
|
* Added --show-adapters flag for windows version.
|
|
* Reworked the SSL/TLS packet acknowledge code to better
|
|
handle certain corner cases.
|
|
* Turned off the default enabling of IP forwarding in the
|
|
sample-scripts/openvpn.init script for Redhat.
|
|
Forwarding can be enabled by users in their --up scripts
|
|
or firewall config.
|
|
* Added --up-restart option based on suggestion from Sean
|
|
Reifschneider.
|
|
* If --dev tap or --dev-type tap is specified, --tun-mtu
|
|
defaults to 1500 and --tun-mtu-extra defaults to 64.
|
|
* Enabled --verb 5 debugging mode that prints 'R' and 'W'
|
|
for each packet read or write on the TCP/UDP socket.
|
|
|
|
2003.08.04 -- Version 1.4.3
|
|
|
|
* Added md5.h include to crypto.c
|
|
to fix build problem on OpenBSD.
|
|
|
|
2003.07.15 -- Version 1.4.2
|
|
|
|
* Removed adaptive bandwidth from
|
|
--mtu-dynamic -- its absence appears
|
|
to work better than its existence (1.4.1.2).
|
|
* Minor changes to --shaper to fix long
|
|
retransmit timeouts at low bandwidth
|
|
(1.4.1.2).
|
|
* Added LOG_RW flag to openvpn.h for
|
|
debugging (1.4.1.2).
|
|
* Silenced spurious configure warnings (1.4.1.2).
|
|
* Backed out --dev-name patch, modified --dev
|
|
to offer equivalent functionality (1.4.1.4).
|
|
* Added an optional parameter to --daemon and
|
|
--inetd to support the passing of a custom
|
|
program name to the system logger (1.4.1.5).
|
|
* Add compiled-in options to the program title
|
|
(1.4.1.5).
|
|
* Coded the beginnings of a WIN32 port (1.4.1.5).
|
|
* Succeeded in porting to Win32 Mingw environment
|
|
and running loopback tests (1.4.1.6). Still
|
|
need a kernel driver for full Win32
|
|
functionality.
|
|
* Fixed a bug in error.h where
|
|
HAVE_CPP_VARARG_MACRO_GCC was misspelled.
|
|
This would have caused a significant slowdown
|
|
of OpenVPN when built by compilers that
|
|
lack ISO C99 vararg macros (1.4.1.6).
|
|
* Created an init script for Gentoo Linux
|
|
in ./gentoo directory (1.4.1.6).
|
|
|
|
2003.05.15 -- Version 1.4.1
|
|
|
|
* Modified the Linux 2.4 TUN/TAP open code to
|
|
fall back to the 2.2 TUN/TAP interface if the
|
|
open or ioctl fails.
|
|
* Fixed bug when --verb is set to 0 and non-fatal
|
|
socket errors occur, causing 100% CPU utilization.
|
|
Occurs on platorms where
|
|
EXTENDED_SOCKET_ERROR_CAPABILITY is defined,
|
|
such as Linux 2.4.
|
|
* Fixed typo in tun.c that was preventing
|
|
OpenBSD build.
|
|
* Added --enable-mtu-dynamic configure option
|
|
to enable --mtu-dynamic experimental option.
|
|
|
|
2003.05.07 -- Version 1.4.0
|
|
|
|
* Added --replay-persist feature to allow replay
|
|
protection across sessions.
|
|
* Fixed bug where --ifconfig could not be used
|
|
with --tun-mtu.
|
|
* Added --tun-mtu-extra parameter to deal with
|
|
the situation where a read on a TUN/TAP device
|
|
returns more data than the device's MTU size.
|
|
* Fixed bug where some IPv6 support code for
|
|
Linux was not being properly ifdefed out for
|
|
Linux 2.2, causing compile errors.
|
|
* Added OPENVPN_EXIT_STATUS_x codes to
|
|
openvpn.h to control which status value
|
|
openvpn returns to its caller (such as
|
|
a shell or inetd/xinetd) for various conditions.
|
|
* Added OPENVPN_DEBUG_COMMAND_LINE flag to
|
|
openvpn.h to allow debugging in situations
|
|
where stdout, stderr, and syslog cannot be used
|
|
for message output, such as when OpenVPN is
|
|
instantiated by inetd/xinetd.
|
|
* Removed owner-execute permission from file
|
|
created by static key generator (Herbert Xu
|
|
and Alberto Gonzalez Iniesta).
|
|
* Added --passtos option to allow IPv4 TOS bits
|
|
to be passed from TUN/TAP input packets to
|
|
the outgoing UDP socket (Craig Knox).
|
|
* Added code to prevent open socket file descriptors
|
|
from being accessible to called scripts.
|
|
* Added --dev-name option (Christian Lademann).
|
|
* Added --mtu-disc option for manual control
|
|
over MTU options.
|
|
* Show OS MTU value on UDP socket write failures
|
|
(linux only).
|
|
* Numerous build system and portability
|
|
fixes (Matthias Andree).
|
|
* Added better sensing of compiler support for
|
|
variable argument macros, including (a) gcc
|
|
style, (b) ISO C 1999 style, and (c) no support.
|
|
* Removed generated files from CVS. Note INSTALL
|
|
file for new CVS build commands.
|
|
* Changed certain internal symbol names
|
|
for C standards compliance.
|
|
* Added TUN/TAP open code to cycle dynamically
|
|
through unit numbers until it finds a free
|
|
unit (based on code from Thomas Gielfeldt
|
|
and VTun).
|
|
* Added dynamic MTU and fragmenting infrastructure
|
|
(Experimental). Rebuild with FRAGMENT_ENABLE
|
|
defined to enable.
|
|
* Minor changes to SSL/TLS negotiation, use
|
|
exponential backoff on retransmits, and use
|
|
a smaller MTU size (note that no protocol
|
|
changes have been made which would break
|
|
compatibility with 1.3.x).
|
|
* Added --enable-strict-options flag
|
|
to ./configure. This option will cause
|
|
a more strict check for options compatibility
|
|
between peers when SSL/TLS negotiation is used,
|
|
but should only be used when both OpenVPN peers
|
|
are of the same version.
|
|
* Reorganization of debugging levels.
|
|
* Added a workaround in configure.ac for
|
|
default SSL header location on Linux
|
|
to fix RH9 build problem.
|
|
* Fixed potential deadlock when pthread support
|
|
is used on OSes that allocate a small socketpair()
|
|
message buffer.
|
|
* Fixed openvpn.init to be sh compliant
|
|
(Bishop Clark).
|
|
* Changed --daemon to wait until all
|
|
initialization is finished before becoming a
|
|
daemon, for the benefit of initialization
|
|
scripts that want a useful return status from
|
|
the openvpn command.
|
|
* Made openvpn.init script more robust, including
|
|
positive indication of initialization errors
|
|
in the openvpn daemon and better sanity checks.
|
|
* Changed --chroot to wait until initialization
|
|
is finished before calling chroot(), and allow
|
|
the use of --user and --group with --chroot.
|
|
* When syslog logging is enabled (--daemon or
|
|
--inetd), set stdin/stdout/stderr to point
|
|
to /dev/null.
|
|
* For inetd instantiations, dup socket descriptor
|
|
to a >2 value.
|
|
* Fixed bug in verify-cn script, where test would
|
|
incorrectly fail if CN=x was the last component
|
|
of the X509 composite string (Anonymous).
|
|
* Added Markus F.X.J. Oberhumer's special
|
|
license exception to COPYING.
|
|
|
|
2002.10.23 -- Version 1.3.2
|
|
|
|
* Added SSL_CTX_set_client_CA_list call
|
|
to follow the canonical form for TLS initialization
|
|
recommended by the OpenSSL docs. This change allows
|
|
better support for intermediate CAs and has no impact
|
|
on security.
|
|
* Added build-inter script to easy-rsa package, to
|
|
facilitate the generation of intermediate CAs.
|
|
* Ported to NetBSD (Dimitri Goldin).
|
|
* Fixed minor bug in easy-rsa/sign-req. It refers to
|
|
openssl.cnf file, instead of $KEY_CONFIG, like all
|
|
other scripts (Ernesto Baschny).
|
|
* Added --days 3650 to the root CA generation command
|
|
in the HOWTO to override the woefully small 30 day
|
|
default (Dominik 'Aeneas' Schnitzer).
|
|
* Fixed bug where --ping-restart would sometimes
|
|
not re-resolve remote DNS hostname.
|
|
* Added --tun-ipv6 option and related infrastructure
|
|
support for IPv6 over tun.
|
|
* Added IPv6 over tun support for Linux (Aaron Sethman).
|
|
* Added FreeBSD 4.1.1+ TUN/TAP driver notes to
|
|
INSTALL (Matthias Andree).
|
|
* Added inetd/xinetd support (--inetd) including
|
|
documentation in the HOWTO.
|
|
* Added "Important Note on the use of commercial certificate
|
|
authorities (CAs) with OpenVPN" to HOWTO based on
|
|
issues raised on the openvpn-users list.
|
|
|
|
2002.07.10 -- Version 1.3.1
|
|
|
|
* Fixed bug in openvpn.spec and openvpn.init
|
|
which caused RPM upgrade to fail.
|
|
|
|
2002.07.10 -- Version 1.3.0
|
|
|
|
* Added --dev-node option to allow explicit selection of
|
|
tun/tap device node.
|
|
* Removed mlockall call from child thread, as it doesn't
|
|
appear to be necessary (child thread inherits mlockall
|
|
state from parent).
|
|
* Added --ping-timer-rem which causes timer for --ping-exit
|
|
and --ping-restart not to run unless we have a remote IP
|
|
address.
|
|
* Added condrestart to openvpn.init and openvpn.spec
|
|
(Bishop Clark).
|
|
* Added --ifconfig case for FreeBSD (Matthias Andree).
|
|
* Call openlog with facility=LOG_DAEMON (Matthias Andree).
|
|
* Changed LOG_INFO messages to LOG_NOTICE.
|
|
* Added warning when key files are group/others accessible.
|
|
* Added --single-session flag for TLS mode.
|
|
* Fixed bug where --writepid would segfault if used with
|
|
an invalid filename.
|
|
* Fixed bug where --ipchange status message was formatted
|
|
incorrectly.
|
|
* Print more concise error message when system() call
|
|
fails.
|
|
* Added --disable-occ option.
|
|
* Added --local, --remote, and --ifconfig options sanity
|
|
check.
|
|
* Changed default UDP MTU to 1300 and TUN/TAP MTU to
|
|
1300.
|
|
* Successfully tested with OpenSSL 0.9.7 Beta 2.
|
|
* Broke out debug level definitions to errlevel.h
|
|
* Minor documentation and web site changes.
|
|
* All changes maintain protocol compatibility
|
|
with OpenVPN versions since 1.1.0, however default
|
|
MTU changes will require setting the MTU explicitly
|
|
by command line option, if you want 1.3.0 to
|
|
communicate with previous versions.
|
|
|
|
2002.06.12 -- Version 1.2.1
|
|
|
|
* Added --ping-restart option to restart
|
|
connection on ping timeout using SIGUSR1
|
|
logic (Matthias Andree).
|
|
* Added --persist-tun, --persist-key,
|
|
--persist-local-ip, and --persist-remote-ip
|
|
options for finer-grained control over SIGUSR1
|
|
and --ping-restart restarts. To
|
|
replicate previous SIGUSR1 functionality,
|
|
use --persist-remote-ip.
|
|
* Changed residual IV fetching code to take
|
|
IV from tail of ciphertext.
|
|
* Added check to make sure that CFB or OFB
|
|
cipher modes are only used with SSL/TLS
|
|
authentication mode, and added a caveat
|
|
to INSTALL.
|
|
* Changed signal handling during initialization
|
|
(including re-initialization during restarts)
|
|
to exit on SIGTERM or SIGINT and ignore other
|
|
signals which would ordinarily be caught.
|
|
* Added --resolv-retry option to allow
|
|
retries on hostname resolution.
|
|
* Expanded the --float option to also
|
|
allow dynamic changes in source port number
|
|
on incoming datagrams.
|
|
* Added --mute option to limit repetitive
|
|
logging of similar message types.
|
|
* Added --group option to downgrade GID
|
|
after initialization.
|
|
* Try to set ifconfig path automatically
|
|
in configure.
|
|
* Added --ifconfig code for Mac OS X
|
|
(Christoph Pfisterer).
|
|
* Moved "Peer Connection Initiated" message
|
|
to --verb level 1.
|
|
* Successfully tested with
|
|
OpenSSL 0.9.7 Beta 1 and AES cipher.
|
|
* Added RPM notes to INSTALL.
|
|
* Added ACX_PTHREAD (from the autoconf
|
|
macro archive) to configure.ac
|
|
to figure out the right pthread
|
|
options for a given platform.
|
|
* Broke out macro definitions from
|
|
configure.ac to acinclude.m4.
|
|
* Minor changes to docs and HOWTO.
|
|
* All changes maintain protocol compatibility
|
|
with OpenVPN versions since 1.1.0.
|
|
|
|
2002.05.22 -- Version 1.2.0
|
|
|
|
* Added configuration file support via
|
|
the --config option.
|
|
* Added pthread support to improve latency.
|
|
With pthread support, OpenVPN
|
|
will offload CPU-intensive tasks such as RSA
|
|
key number crunching to a background thread
|
|
to improve tunnel packet forwarding
|
|
latency. pthread support can be enabled
|
|
with the --enable-pthread configure option.
|
|
Pthread support is currently available
|
|
only for Linux and Solaris.
|
|
* Added --dev-type option so that tun/tap
|
|
device names don't need to begin with
|
|
"tun" or "tap".
|
|
* Added --writepid option to write main
|
|
process ID to a file.
|
|
* Numerous portability fixes to ease
|
|
porting to other OSes including changing
|
|
all network types to uint8_t and uint32_t,
|
|
and not assuming that time_t is 32 bits.
|
|
* Backported to OpenSSL 0.9.5.
|
|
* Ported to Solaris.
|
|
* Finished OpenBSD port except for
|
|
pthread support.
|
|
* Added initialization script:
|
|
sample-scripts/openvpn.init
|
|
(Douglas Keller)
|
|
* Ported to Mac OS X (Christoph Pfisterer).
|
|
* Improved resilience to DoS attacks when
|
|
TLS mode is used without --remote or
|
|
--tls-auth, or when --float is used
|
|
with --remote. Note however that the best
|
|
defense against DoS attacks in TLS mode
|
|
is to use --tls-auth.
|
|
* Eliminated automake/autoconf dependency
|
|
for non-developers.
|
|
* Ported configure.in to configure.ac
|
|
and autoconf 2.50+.
|
|
* SIGHUP signal now causes OpenVPN to restart
|
|
and re-read command line and or config file,
|
|
in conformance with canonical daemon behaviour.
|
|
* SIGUSR1 now does what SIGHUP did in
|
|
version 1.1.1 and earlier -- close and reopen
|
|
the UDP socket for use when DHCP changes
|
|
host's IP address and preserve most recently
|
|
authenticated peer address without rereading
|
|
config file.
|
|
* SIGUSR2 added -- outputs current statistics,
|
|
including compression statistics.
|
|
* All changes maintain protocol compatibility
|
|
with 1.1.1 and 1.1.0.
|
|
|
|
2002.04.22 -- Version 1.1.1
|
|
|
|
* Added --ifconfig option to automatically configure
|
|
TUN device.
|
|
* Added inactivity disconnect (--inactive
|
|
and --ping-exit options).
|
|
* Added --ping option to keep stateful firewalls
|
|
from timing out.
|
|
* Added sanity check to command line parser to
|
|
err if any TLS options are used in non-TLS mode.
|
|
* Fixed build problem with compiler environments that
|
|
define printf as a macro.
|
|
* Fixed build problem on linux systems that have
|
|
an integrated TUN/TAP driver but lack the persistent
|
|
tunnel feature (TUNSETPERSIST). Some linux kernels
|
|
>= 2.4.0 and < 2.4.7 fall into this category.
|
|
* Changed all calls to EVP_CipherInit to use explicit
|
|
encrypt/decrypt mode in order to fix problem with
|
|
IDEA-CBC and AES-256-CBC ciphers.
|
|
* Minor changes to control channel transmit limiter
|
|
algorithm to fix problem where TLS control channel
|
|
might not renegotiate within the default 60 second window.
|
|
* Simplified man page examples by taking advantage
|
|
of the new --ifconfig option.
|
|
* Minor changes to configure.in to check more
|
|
rigourously for OpenSSL 0.9.6 or greater.
|
|
* Put back openvpn.spec, eliminated
|
|
openvpn.spec.in.
|
|
* Modified openvpn.spec to reflect new automake-based
|
|
build environment (Bishop Clark).
|
|
* Other documentation changes.
|
|
* Added --test-crypto option for debugging.
|
|
* Added "missing" and "mkinstalldirs" automake
|
|
support files.
|
|
|
|
|
|
2002.04.09 -- Version 1.1.0
|
|
|
|
* Strengthened replay protection and IV handling,
|
|
extending it fully to both static key and
|
|
TLS dynamic key exchange modes.
|
|
* Added --mlock option to disable paging and ensure that key
|
|
material and tunnel data is never paged to disk.
|
|
* Added optional traffic shaping feature to cap the maximum
|
|
data rate of the tunnel.
|
|
* Converted to automake (The Platypus Brothers 2002-04-01).
|
|
* Ported to OpenBSD by Janne Johansson.
|
|
* Added --tun-af-inet option to work around an incompatibility
|
|
between Linux and BSD tun drivers.
|
|
* Sequence number-based replay protection using the
|
|
IPSec sliding window model is now the default,
|
|
disable with --no-replay.
|
|
* Explicit IV is now the default, disable with --no-iv.
|
|
* Disabled all cipher modes except CBC, CFB, and OFB.
|
|
* In CBC mode, use explicit IV and carry forward residuals,
|
|
using IPSec model.
|
|
* In CFB/OFB mode, IV is timestamp, sequence number.
|
|
* Eliminated --packet-id, --timestamp, and max-delta parameter to
|
|
the --tls-auth option as they are now supplanted by improved
|
|
replay code which is enabled by default.
|
|
* Eliminated --rand-iv as it is now obsolete with improved
|
|
IV code.
|
|
* Eliminated --reneg-err option as it increases vulnerability
|
|
to DoS attacks.
|
|
* Added weak key check for DES ciphers.
|
|
* --tls-freq option is no longer specified on the command line,
|
|
instead it now inherits its parameter from the
|
|
--tls-timeout option.
|
|
* Fixed bug that would try to free memory on exit that was
|
|
never malloced if --comp-lzo was not specified.
|
|
* Errata fixed in the man page examples: "test-ca" should be
|
|
"tmp-ca".
|
|
* Updated manual page.
|
|
* Preliminary work in porting to OpenSSL 0.9.7.
|
|
* Changed license to allowing linking with OpenSSL.
|
|
|
|
2002.03.29 -- Version 1.0.3
|
|
|
|
* Fixed a problem in configure with library ordering on the
|
|
command line.
|
|
|
|
2002.03.28 -- Version 1.0.2
|
|
|
|
* Improved the efficiency of the inner event loop.
|
|
* Fixed a minor bug with timeout handling.
|
|
* Improved the build system to build on RH 6.2 through 7.2.
|
|
* Added an openvpn.spec file for RPM builders (Bishop Clark).
|
|
|
|
2002.03.23 -- Version 1.0
|
|
|
|
* Added TLS-based authentication and key exchange.
|
|
* Added gremlin mode to stress test.
|
|
* Wrote man page.
|
|
|
|
2001.12.26 -- Version 0.91
|
|
|
|
* Added any choice of cipher or HMAC digest.
|
|
|
|
2001.5.13 -- Version 0.90
|
|
|
|
* Initial release.
|
|
* IP tunnel over UDP, with blowfish cipher and SHA1 HMAC signature.
|
