2010-04-29Fix certificate serial number exportDavide Brini3-5/+120
contrib/OCSP_check/OCSP_check.sh: New barebone script to demonstrate how to use $tls_serial_{n} to perform simple OCSP queries using OpenSSL command line "openssl ocsp". Minimal sanity checks to fail if user tries to use it without customizing. openvpn.8: Added some notes about $tls_serial_{n} format and usage to the existing description. ssl.c: correctly manage and export serial numbers of any size (as parsed by OpenSSL) into the environment. Set to empty string in case of errors, as 0 and negative numbers are all possible (although illegal) certificate serial numbers. Use an OpenSSL BIO object to do the job. Conforms to coding style guidelines. See the discussion at http://article.gmane.org/gmane.network.openvpn.devel/3588 for more details.

2010-04-29Enhance contrib/pull-resolv-conf/client.{up,down} scriptsDavide Brini2-69/+64
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.

2010-04-29Harden create_temp_filename() (version 2)David Sommerseth2-16/+48
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.

2010-04-29The man page needs dash escaping in UTF-8 environmentsJan Brinkmann1-806/+806
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.

2010-04-29bash->bourne script cleanupDan Nelson17-17/+17
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. sf.net tracker: <https://sourceforge.net/tracker/?func=detail&aid=2040296&group_id=48978&atid=454721> Discussed on the IRC meeting March 4, 2010 in #openvpn-discussions. <http://thread.gmane.org/gmane.network.openvpn.devel/3242> Signed-off-by: David Sommerseth <dazo@users.sourceforge.net> Acked-by: James Yonan <james@openvpn.net>
2010-04-29Allow 'lport 0' setup for random port bindingEnrico Scholz1-1/+1
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)) | { in options.c seems to be the only required change.

2010-04-29verb 5 logging wrongly reports received bytesDavid Sommerseth1-2/+2
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.

2010-04-29[PATCH] Change verify-cn so cn is no longer hardcoded in openvpn's config fileKarl O. Pinc1-15/+27
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.

2009-10-01client-kill management interface command, when issued on server, willjames6-7/+41
now send a RESTART message to client. 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. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@5021 e7ae566f-a301-0410-adde-c780ea21d3b5

2009-09-29Added the ability for the server to provide a custom reason stringjames8-14/+84
when an AUTH_FAILED message is returned to the client. This string can be set by the server-side managment interface and read by the client-side management interface. For more info, see management/management-notes.txt, and look for references to "client-reason-text". git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@5012 e7ae566f-a301-0410-adde-c780ea21d3b5
2009-09-28Fixed a bug introduced in r4436 (2.1_rc17) where using thejames1-2/+2
redirect-gateway option by itself, without any extra parameters, would cause the option to be ignored. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@5011 e7ae566f-a301-0410-adde-c780ea21d3b5
2009-09-28Added --server-poll-timeout option : when polling possible remotejames8-0/+70
servers to connect to in a round-robin fashion, spend no more than n seconds waiting for a response before trying the next server. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@5010 e7ae566f-a301-0410-adde-c780ea21d3b5
2009-09-27Eliminated the limitation on the number of options that can be pushedjames16-115/+271
to clients, including routes. Previously, all pushed options needed to fit within a 1024 byte options string. Remember that to make use of this feature to allow many routes to be pushed to clients, the client config file must specify the max-routes option, and the number of pushed routes cannot exceed this limit. Also, both server and client must include this commit. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@4991 e7ae566f-a301-0410-adde-c780ea21d3b5
2009-09-17The maximum number of "route" directives (specified in the configjames8-30/+86
file or pulled from a server) can now be configured via the new "max-routes" directive. Previously, the limit was set to 100 and fixed by a compile-time constant. Now the limit is dynamic and can be modified by the "max-routes" directive. If max-routes is not specified, the default limit is 100. Note that this change does not address the maximum size of the pushed options string sent from server to client, which is still controlled by the TLS_CHANNEL_BUF_SIZE compile-time constant. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@4967 e7ae566f-a301-0410-adde-c780ea21d3b5
2009-09-16Modified client to send a PUSH_REQUEST message to server 1 secondjames3-5/+14
after connection initiation rather than 0 seconds after. Successive PUSH_REQUEST messages after the first will continue to be sent at 5 second intervals until a response is received. This tends to speed up the client connection sequence by 4 seconds because the first PUSH_REQUEST message is usually sent too soon and is dropped, causing a wait of 5 seconds until the next PUSH_REQUEST message is sent.

2009-05-24Added new 'autolocal' redirect-gateway flag. When enabled, the OpenVPNjames6-33/+119
client will examine the routing table and determine whether (a) the OpenVPN server is reachable via a locally connected interface, or (b) traffic to the server must be forwarded through the default router. Only add a special bypass route for the OpenVPN server if (b) is true. If (a) is true, behave as if the 'local' flag is specified, and do not add a bypass route. The new 'autolocal' flag depends on the non-portable test_local_addr() function in route.c, which is currently only implemented for Windows. The 'autolocal' flag will act as a no-op on platforms that have not yet defined a test_local_addr() function. Increased TLS_CHANNEL_BUF_SIZE to 2048 from 1024 (this will allow for more option content to be pushed from server to client). Raised D_MULTI_DROPPED debug level to 4 from 3.

2008-11-03Fixed some ifconfig-pool issues that precludedjames3-10/+12
it from being combined with --server directive. Now, for example, we can configure thusly: server 10.8.0.0 255.255.255.0 nopool ifconfig-pool 10.8.0.2 10.8.0.99 255.255.255.0 to have ifconfig-pool manage only a subset of the VPN subnet. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3471 e7ae566f-a301-0410-adde-c780ea21d3b5

2008-10-28Modified pkitool to allow flexibility in separatingjames1-14/+20
the Common Name convention from the cert/key filename convention. For example: KEY_CN="James's Laptop" KEY_NAME="james" ./pkitool james will crete a client certificate/key pair of james.crt/james.key having a Common Name of "James's Laptop" and a Name of "james". git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3463 e7ae566f-a301-0410-adde-c780ea21d3b5

2008-09-06Modified ip_or_dns_addr_safe, which validates pulled DNS names,james2-4/+16

2008-09-062.1_rc8 and earlier did implicit shell expansion on scriptjames9-363/+350
arguments since all scripts were called by system(). The security hardening changes made to 2.1_rc9 no longer use system(), but rather use the safer execve or CreateProcess system calls. The security hardening also introduced a backward incompatibility with 2.1_rc8 and earlier in that script parameters were no longer shell-expanded, so for example: client-connect "docc CLIENT-CONNECT" would fail to work because execve would try to execute a script called "docc CLIENT-CONNECT" instead of "docc" with "CLIENT-CONNECT" as the first argument. This patch fixes the issue, bringing the script argument semantics back to pre 2.1_rc9 behavior in order to preserve backward compatibility while still using execve or CreateProcess to execute the script/executable. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3311 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-09-04Added --allow-pull-fqdn option which allows client to pull DNS namesjames5-12/+45
from server (rather than only IP address) for --ifconfig, --route, and --route-gateway. OpenVPN versions 2.1_rc7 and earlier allowed DNS names for these options to be pulled and translated to IP addresses by default. Now --allow-pull-fqdn will be explicitly required on the client to enable DNS-name-to-IP-address translation of pulled options. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3307 e7ae566f-a301-0410-adde-c780ea21d3b5

2008-08-05Added additional warnings to flag common gotchas:james5-27/+133
* Warn when ethernet bridging that the IP address of the bridge adapter is probably not the same address that the LAN adapter was set to previously. * When running as a server, warn if the LAN network address is the all-popular 192.168.[0|1].x, since this condition commonly leads to subnet conflicts down the road. * Primarily on the client, check for subnet conflicts between the local LAN and the VPN subnet. Added a 'netmask' parameter to get_default_gateway, to return the netmask of the adapter containing the default gateway. Only implemented on Windows so far. Other platforms will return 255.255.255.0. Currently the netmask information is only used to warn about subnet conflicts. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3179 e7ae566f-a301-0410-adde-c780ea21d3b5

DHCP proxy mode: Configure server mode for ethernet bridging using a DHCP-proxy, where clients talk to the OpenVPN server-side DHCP server to receive their IP address allocation and DNS server addresses. Added "--route-gateway dhcp", to enable the extraction of the gateway address from a DHCP negotiation with the OpenVPN server-side LAN. Modified client.conf and server.conf to reflect new option modes.

2008-07-26Completely revamped the system for calling external programs and scripts:james23-420/+1098
* All external programs and scripts are now called by execve() on unix and CreateProcess on Windows. * The system() function is no longer used. * Argument lists for external programs and scripts are now built by the new argv_printf function which natively outputs to string arrays (i.e. char *argv[] lists), never truncates its output, and eliminates the security issues inherent in formatting and parsing command lines, and dealing with argument quoting. * The --script-security directive has been added to offer policy controls on OpenVPN's execution of external programs and scripts. Also added a new plugin example (openvpn/plugin/examples/log.c) that logs information to stdout for every plugin method called by OpenVPN. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3122 e7ae566f-a301-0410-adde-c780ea21d3b5

success/error, and any truncation of output due to an insufficiently large output buffer will be cause for error. In verify_callback, read X509 Subject Name without truncation.

2008-07-17Previously, OpenVPN might log a client's auth-user-passjames3-2/+19
password if the verbosity was set to a high debug level such as 7 or higher. Normally this would only be used by developers. Now, even at high debug levels, the password will not be output. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3073 e7ae566f-a301-0410-adde-c780ea21d3b5

2008-07-17Call prng_init after fork in background processjames1-0/+4
created by port_share_open, so as to ensure a newly seeded PRNG sequence. This is strictly defensive programming since port_share_proxy currently does not use the PRNG. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3070 e7ae566f-a301-0410-adde-c780ea21d3b5

git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3066 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-17Support wraparound of reliable.[ch] packet IDs. Injames1-12/+44
practice, wraparound of the packet ID sequence is extremely unlikely since the sequence is restarted for each mid-session TLS renegotiation. But we will support it for completeness. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3065 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-17Fixed a potential information leak in the new NTLM phase 3 code,james2-8/+21
as well as a failure of the code to check the return value from base64_decode. Fixed compiler warnings in the new NTLM phase 3 code about implicit casting between signed and unsigned char *. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3064 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-17Fixed issue in read_key_file, where the return value ofjames1-1/+3
read() wasn't being checked for errors. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3063 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-16Added SOCKET_SND_RCV_BUF_MAX constant (set to 1000000) to limit thejames2-5/+16
maximum size passed to setsockopt SNDBUF/RCVBUF. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3062 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-16In the Windows version of tun_finalize, on errors that wouldjames1-1/+6
return -1, set buf->len to 0 rather than -1. While downstream code is set up to consider the buffer invalidated if its length is <= 0, this change makes the code cleaner and safer. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3061 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-16Used unlikely() macro to tell compiler that msg() willjames1-1/+1
usually be silent. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3060 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-16Added likely() and unlikely() branch prediction hint macrosjames4-21/+68
to syshead.h Introduced BUF_MAX constant to limit struct buffer offset and length values. BUF_MAX has been set to 2^20. Use likely() and unlikely() macros in buffer.h code to allow the compiler to generate more efficient code. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3058 e7ae566f-a301-0410-adde-c780ea21d3b5
