For my company, we use a PKI (linked to a LDAP) with OpenVPN. We can't use "CN" to be
username (few people can have the same "CN"). In our case, we only use the UID.
With my patch, you can choose another field to be username with a new option called

Solves bug ticket 13
<https://community.openvpn.net/openvpn/ticket/13>
When the client sends PUSH_REQUESTS, it waits until the server sends PUSH_REPLY.
If the server do not have anything to push to the client nothing happens. The
client will then regularly send new PUSH_REQUESTS until it gets an answer, which
results in not completing the connection negotiation.
This patch makes the server send an empty PUSH_REPLY when it has nothing to more
to push to the client.

contrib/OCSP_check/OCSP_check.sh:
I discovered that, quite surprisingly, the exit status of "openssl ocsp"
is 0 even if the certificate status is "revoked". This means that the
logic of the script needs to be rewritten so that it parses the output
returned by the query and explicitly looks for a
"0x<serial number>: good"
line, and exit if either the command has a non-zero exit status, or the
above line is not found.
Doing that portably without bashisms requires some juggling around, so
perhaps the code is slightly less clean now, but it does have many
comments.

This patch fixes two bugs introduced in
commit 339f2a4d4b487afa53fa99d72c35b16f31e417d3
Author: David Sommerseth <dazo@users.sourceforge.net>
Date: Thu Apr 29 23:35:45 2010 +0200
David's patch replaced openvpn_execve() with openvpn_run_script() in two places,
but didn't adjust the return value handling. openvpn_run_script() returns true
or false, while openvpn_execve() returns the program's exit code.
Without the fix, the --tls-verify script and the --auth-user-pass-verify
script fail to run. (I noticed the latter, but haven't actually tested the
former.)
The return value handling is fine for the other places where
openvpn_run_script() is used, because those places previously used
openvpn_execve_check() (notice the "_check" suffix).

The main task of this patch is to avoid reporting the SCRIPT_SECURITY_WARNING
over and over again, in addition to not show this warning when it should not
be a problem. This general warning should now only appear once, and only when
--script-security is not set, 0 or 1. In all other cases this warning should
not appear.
In addition, this warning will come close to the script-hook which most probably
will fail. It will also give a little bit more concrete hint on which script-hook
which failed. If --script-security is 2 or 3, only the execve failure itself will
be shown. This message will on the other hand be shown repeatedly.
This is a new rewritten version which simplifies the implementaion of the new
openvpn_run_script() function. It was considered to remove it completely, but
due to code clearity and easy of use it was decided to make this function a static
inline function instead. Anyhow, this function will enforce openvpn_execve_check()
to be called with the S_SCRIPT flag.

Patch arrived from Davide Brini:
- No more bashisms (AFAICT). Should work with any POSIX-compatible shell
(which means "almost all reasonably recent shells"), though I've only tested
with bash and dash.
- Unnecessary calls to external tools (sed) removed
- Manages multiple DNS and DOMAIN options. Each DNS option becomes a
"nameserver" line in the new resolv.conf (up to a maximum of 3). If there's a
single DOMAIN option, it becomes a "domain" line in resolv.conf; otherwise,
all the domains are listed in a "search" line in resolv.conf (eg "search
foo.com example.net").
- Client.up renames the existing resolv.conf and creates a brand new one;
client.down restores it from the saved copy when the VPN terminates (the usual
rules about running as root apply). This is how Gentoo does that; the old
scripts instead added/removed some lines at the beginning of the file, which
looks a less clean approach to me. The rename approach also dramatically
simplifies and shortens client.down, as you'll see.
- Uses resolvconf if it's available (detected by the presence of
/sbin/resolvconf) rather than writing to resolv.conf directly. Not sure
whether this is a Linux-only thing or other systems use it though.
Script has been smoke tested on Fedora 12 with OpenVPN 2.1.1 without
the resolvconf package , and in addition Debian Lenny with
OpenVPN 2.1_rc11 according to the patch.

By hardening the create_temp_filename() function to check if the generated
filename exists and to create the temp file with only S_IRUSR|S_IWUSR bit
files set before calling the script, it should become even more difficult to
exploit such a scenario.
After a discussion on the mailing list, Fabian Knittel provided an enhanced
version of the inital patch which is added to this patch.
This patch also renames create_temp_filename() to create_temp_file(), as this
patch also creates the temporary file. The function returns the filename of the
created file, or NULL on error.

There was a debian bugreport which was filed in 2005 . It was patched but
it seems that nobody forwarded the patch to the openvpn project itself.
The problem is quite simple:
The dashes for options (the double dashes) are not escaped. This causes
trouble in relationship with utf-8 .
Since the bugreport was closed it was patched within the debian/ubuntu
packages itself. I've attached the patch to get it atleast reviewed by the
openvpn project itself.

Many of the scripts in the openvpn source have their shell set to
/bin/bash, but only two use bash features. The attached patch (against
openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for
better portability. The only scripts that actually require bash are
contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable
indirection feature.

I am running a multihomed host where 'local <extip>' must be specified
for proper operation. Unfortunately, this implies 'lport 1194' or
another static port.
This causes problems with stateful firewalls which register the host/port
pairs in the internal connection tracking table. On ungraceful reconnects,
the new TCP connection will have same the host/port pairs but unexpected
sequence numbers. The new connection will be assumed as invalid hence and
be dropped.
It would be nice when local port can be configured to be bound to a
random port number. After reading code,
| else if (streq (p[0], "lport") && p[1])
| ...
| port = atoi (p[1]);
|- if (!legal_ipv4_port (port))
|+ if (port != 0 && !legal_ipv4_port (port))

With --verb 5, openvpn logs a single letter (rwRW) for each package
received or sent. I recently ran into a problem with the tun device on
Linux where the read from that device returned 0. Unfortunately this was
also logged as "r", which made me assume that openvpn had received
something, while it actually hadn't.
(See https://dev.openwrt.org/ticket/6650 for the bug that made me find out
about this problem with openvpn.)
I'm attaching a patch which prevents openvpn from logging "r" or "R" when
it didn't actually read anything. This is against openvpn 2.1-rc20, but
probably still applies to the most recent version.

This patch should be easy to process.
A resubmission of the patch sent to this list on 04/23/2009.
The patch changes the verify-cn script sample
to be used with --tls-verify so that instead of having
to hardcode a cn to verify in the OpenVPN configuration file
the allowed cns may be written into a separate file.
This makes the process of verifying cns a whole
lot more dynamic, to the point where it is useful
in the real world.
One problem with this patch is that it is backwards
incompatible. I did not bother keeping the original
calling interface as A) it's a sample script, and B) the
original's functionality seems useless
and equalivant functionality is easily available
with the new script.
The problem with the original is that there seems
little point in verifying a client's cn when all
the clients share one cn, as would have to be
the case when the cn is hardcoded into the openvpn
config file.
This patch applies against the testing allmiscs branch,
and should apply against any of the other testing
branches as well.
It works for me. I've tested it throughly but not
used it extensively in production.

Patch arrived from Davide Brini:
- No more bashisms (AFAICT). Should work with any POSIX-compatible shell
(which means "almost all reasonably recent shells"), though I've only tested
with bash and dash.
- Unnecessary calls to external tools (sed) removed
- Manages multiple DNS and DOMAIN options. Each DNS option becomes a
"nameserver" line in the new resolv.conf (up to a maximum of 3). If there's a
single DOMAIN option, it becomes a "domain" line in resolv.conf; otherwise,
all the domains are listed in a "search" line in resolv.conf (eg "search
foo.com example.net").
- Client.up renames the existing resolv.conf and creates a brand new one;
client.down restores it from the saved copy when the VPN terminates (the usual
rules about running as root apply). This is how Gentoo does that; the old
scripts instead added/removed some lines at the beginning of the file, which
looks a less clean approach to me. The rename approach also dramatically
simplifies and shortens client.down, as you'll see.
- Uses resolvconf if it's available (detected by the presence of
/sbin/resolvconf) rather than writing to resolv.conf directly. Not sure
whether this is a Linux-only thing or other systems use it though.
Script has been smoke tested on Fedora 12 with OpenVPN 2.1.1 without
the resolvconf package , and in addition Debian Lenny with
OpenVPN 2.1_rc11 according to the patch.

By hardening the create_temp_filename() function to check if the generated

files set before calling the script, it should become even more difficult to
exploit such a scenario.
After a discussion on the mailing list, Fabian Knittel provided an enhanced

There was a debian bugreport which was filed in 2005 . It was patched but
it seems that nobody forwarded the patch to the openvpn project itself.
The problem is quite simple:
The dashes for options (the double dashes) are not escaped. This causes
trouble in relationship with utf-8 .
Since the bugreport was closed it was patched within the debian/ubuntu
packages itself. I've attached the patch to get it atleast reviewed by the
openvpn project itself.

Many of the scripts in the openvpn source have their shell set to
/bin/bash, but only two use bash features. The attached patch (against
openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for
better portability. The only scripts that actually require bash are
contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable
indirection feature.

I am running a multihomed host where 'local <extip>' must be specified
for proper operation. Unfortunately, this implies 'lport 1194' or
another static port.
This causes problems with stateful firewalls which register the host/port
pairs in the internal connection tracking table. On ungraceful reconnects,
the new TCP connection will have same the host/port pairs but unexpected
sequence numbers. The new connection will be assumed as invalid hence and
be dropped.
It would be nice when local port can be configured to be bound to a
random port number. After reading code,
| else if (streq (p[0], "lport") && p[1])
| ...
| port = atoi (p[1]);
|- if (!legal_ipv4_port (port))

With --verb 5, openvpn logs a single letter (rwRW) for each package
received or sent. I recently ran into a problem with the tun device on
Linux where the read from that device returned 0. Unfortunately this was
also logged as "r", which made me assume that openvpn had received
something, while it actually hadn't.
(See https://dev.openwrt.org/ticket/6650 for the bug that made me find out
about this problem with openvpn.)
I'm attaching a patch which prevents openvpn from logging "r" or "R" when
it didn't actually read anything. This is against openvpn 2.1-rc20, but
probably still applies to the most recent version.

This patch should be easy to process.
A resubmission of the patch sent to this list on 04/23/2009.
The patch changes the verify-cn script sample
to be used with --tls-verify so that instead of having
to hardcode a cn to verify in the OpenVPN configuration file
the allowed cns may be written into a separate file.
This makes the process of verifying cns a whole
lot more dynamic, to the point where it is useful
in the real world.
One problem with this patch is that it is backwards
incompatible. I did not bother keeping the original
calling interface as A) it's a sample script, and B) the
original's functionality seems useless
and equalivant functionality is easily available
with the new script.
The problem with the original is that there seems
little point in verifying a client's cn when all
the clients share one cn, as would have to be
the case when the cn is hardcoded into the openvpn
config file.
This patch applies against the testing allmiscs branch,
and should apply against any of the other testing
branches as well.
It works for me. I've tested it throughly but not
used it extensively in production.

This patch should be easy to process.
A resubmission of the patch sent to this list on 04/23/2009.
The patch changes the verify-cn script sample
to be used with --tls-verify so that instead of having
to hardcode a cn to verify in the OpenVPN configuration file
the allowed cns may be written into a separate file.
This makes the process of verifying cns a whole
lot more dynamic, to the point where it is useful
in the real world.
One problem with this patch is that it is backwards
incompatible. I did not bother keeping the original
calling interface as A) it's a sample script, and B) the
original's functionality seems useless
and equalivant functionality is easily available
with the new script.
The problem with the original is that there seems
little point in verifying a client's cn when all
the clients share one cn, as would have to be
the case when the cn is hardcoded into the openvpn
config file.
This patch applies against the testing allmiscs branch,
and should apply against any of the other testing
branches as well.
It works for me. I've tested it throughly but not
used it extensively in production.

"openvpn login OURDOMAIN+USERNAME password PASSWORD"
Finally I turned on more verbose logging and found that the plugin did
not recognize "USERNAME" as something to replace, because it expected
the string to be surrounded by whitespace. I wrote the following patch
to correct this. I hope you find it useful,

This is a modified version of a patch sent to the sf.net
patch tracker:
<http://sourceforge.net/tracker/?func=detail&aid=2491190&group_id=48978&atid=454721>
After having disucssed this patch on IRC (#openvpn-discussions)
March 4, 2010, it was decided to accept this patch when not modifying
TARGET_* defines through out the code. Further, in a mail comment
Alon Bar-Lev had some other comments of what would be needed to be done.
Mail reference:
<http://thread.gmane.org/gmane.network.openvpn.devel/3176>
This patch has been tested by bootstrapping the code on a RHEL4.6 box.
with the following autotools packages installed:
autoconf-2.59-5
automake-1.9.2-3
libtool-1.5.6-4.EL4.2
It builds cleanly and 'make check' passes.

There was a debian bugreport which was filed in 2005 . It was patched but
it seems that nobody forwarded the patch to the openvpn project itself.
The problem is quite simple:
The dashes for options (the double dashes) are not escaped. This causes
trouble in relationship with utf-8 .
Since the bugreport was closed it was patched within the debian/ubuntu
packages itself. I've attached the patch to get it atleast reviewed by the
openvpn project itself.
See <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=296133> for details.

Many of the scripts in the openvpn source have their shell set to
/bin/bash, but only two use bash features. The attached patch (against
openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for
better portability. The only scripts that actually require bash are
contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable
indirection feature.

I am running a multihomed host where 'local <extip>' must be specified
for proper operation. Unfortunately, this implies 'lport 1194' or
another static port.
This causes problems with stateful firewalls which register the host/port
pairs in the internal connection tracking table. On ungraceful reconnects,
the new TCP connection will have same the host/port pairs but unexpected
sequence numbers. The new connection will be assumed as invalid hence and
be dropped.
It would be nice when local port can be configured to be bound to a
random port number. After reading code,
| else if (streq (p[0], "lport") && p[1])

With --verb 5, openvpn logs a single letter (rwRW) for each package
received or sent. I recently ran into a problem with the tun device on
Linux where the read from that device returned 0. Unfortunately this was
also logged as "r", which made me assume that openvpn had received
something, while it actually hadn't.
(See https://dev.openwrt.org/ticket/6650 for the bug that made me find out
about this problem with openvpn.)
I'm attaching a patch which prevents openvpn from logging "r" or "R" when
it didn't actually read anything. This is against openvpn 2.1-rc20, but
probably still applies to the most recent version.

It should be nice to enhance tls-verify check possibilities against peer
cert during a pending TLS connection like :
- OCSP verification
- check any X509 extensions of the peer certificate
- delta CRL verification
- ...
This patch add a new "tls-export-cert" option which allow to get peer
certificate in PEM format and to store it in an openvpn temporary file.
Peer certificate is stored before tls-script execution and deleted after.
The name of the related temporary file is available under tls-verify
script by an environment variable "peer_cert".
The patch was made from OpenVPN svn Beta21 branches.
Here is a very simple exemple of Tls-verify script which provide OCSP
support to OpenVPN (with tls-export-cert option) without any OpenVPN
"core" modification :
X509=$2
openssl ocsp \
-issuer /etc/openvpn/ssl.crt/RootCA.pem \
-CAfile /etc/openvpn/ssl.capath/OpenVPNServeur-cafile.pem \
-cert $peer_cert \
-url http://your-ocsp-url
if [ $? -ne 0 ]
then
echo "error : OCSP check failed for ${X509}" | logger -t
"tls-verify"
exit 1
fi

1. Fail gracefully rather than segfault if calloc returns NULL.
2. The openvpn_plugin_abort_v1 function can potentially be called
with handle == NULL. Add code to detect this case, and if
so, avoid dereferencing pointers derived from handle.
(Thanks to David Sommerseth for finding this bug).

or "dhcp-renew" options were combined with "route-gateway dhcp".
The problem is that the IP Helper functions for DHCP release and
renew are blocking, and so calling them from a single-threaded
client stops tunnel traffic forwarding, and hence breaks
"route-gateway dhcp" which requires an active tunnel. The fix is
to call the IP Helper functions for DHCP release and renew from
another process.

This feature is intended to make UDP clients respond the same as TCP
clients in the case where the server issues a RESTART message in
order to force the client to reconnect and pull a new options/route
list.
