* Add openssl-specific common cipher list names to ssl.c.Steffan Karger2014-03-231-0/+13
| | | | | | | | | | | This adds a number of commonly used cipher list names to ssl.c, which makes OpenVPN not give a "translation not found" warning when using these.

* Replace copied structure elements with including <net/route.h>Gert Doering2014-01-161-93/+2
| | | | | | | | | | | | | | | | | | | | | | The code for FreeBSD, Dragonfly, OpenBSD and NetBSD contained copies of structures from <net/route.h> (struct rt_msghdr in particular). OpenBSD changed some structure elements, making OpenVPN incompatible, depending on the specific OpenBSD version. Clean up: remove copied definitions, replace by including <net/route.h> directly - this could not be done originally due to a conflict with "struct route" in OpenVPN and <net/route.h>, cleaned up by the previous commit. Tested on FreeBSD 9.1-RELEASE, NetBSD 5.1, OpenBSD 4.9 (route.c compiles with no warnings, and "openvpn --show-gateway" works, which is the only part of the code that uses the structures in question).

* Fix spurious ignoring of pushed config options (trac#349).Jens Wagner2014-01-073-1/+5
| | | | | | | | | | | | | | | | | | | | | | | The function incoming_push_message(...) in push.c uses a local variable option_types_found, that gets passed to do_up(...). If the server push got split into several parts, only the last part (PUSH_MSG_REPLY) option_types_found is used for do_up (initilized as 0 locally), the previous ones (PUSH_MSG_CONTINUATION) are ignored. So e.g. a ping config, pushed by the server in the first push, followed by a lot of "push route" configs, causing a second push message, will have the do_up() called, but without e.g. the OPT_P_TIMER flag, so those options will be silently ignored. The patch resolves that, by introducing "push_option_types_found" in "c->options" and using that as storage. Fix trac bug #349.

* Remove OpenSSL tmp_rsa_callback. Removes support for ephemeral RSA in TLS.Steffan Karger2014-01-031-18/+0
| | | | | | | | | | | | | | | | | | | | | This code would not really generate ephemeral keys every time it is called, but a single key that would be reused during process lifetime and returned each time the function was called; probably not what users would expect. TLS allowes ephemeral keys to be used only when no other key exchange, such as (ephemeral) Diffie-Hellman, is performed. The end result is that it was only used by a number of (weak) export ciphers, which could give users a false sense of security. So, instead of fixing a weak cipher mode, we'll just remove support for it completely. Plenty of better alternatives are available in TLS.

| | | | | | | | | | | The "ipv6only" setsockopt logic introduced by 8832c6c4cf was inverted, fix. Also add a msg() to show what value is set, as that makes strange v4/v6 connectivity problems much easier to spot.

* Implement dual stack client support for OpenVPNArne Schwabe2013-11-2914-632/+671
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains a number of changes. I did not further spit this since some changes make only sense being changed together. Always use connection_list, simplifies the reconnection logic. Change meaning of --connect-retry-max and --connect-retry to be used all connections. This now allows OpenVPN to quit after n unsuccessful udp connection attempts Remove the tcp reconnection logic. Failing a TCP connection will now cause a USR1 like a UDP connection. Also extend sig->source from bool to int to specify signal source. This allows a finer grained reconnection logic if necessary in the future. Dual-Stack support: if an address resolves to multiple records each address is tried in sequential order. Then proceed to next connection entry. Introduce the field current_remote to represent the current connecting remote. Also change some fields to struct addrinfo* form openvn_addr to store multiple addresses needed for the dual stack support. Change meaning from udp and tcp to allow both IPv4 and IPv6. Introducue new udp4 and tcp4 to force IPv4.

* change the type of 'remote' to addrinfo*, and rename to 'remote_list'.Arne Schwabe2013-11-275-39/+111
| | | | | | | | | | | | | | | | | Warning: this is work in progress, preparing for the full dual-stack client patch. With this commit in place, connecting via "--proto udp" or "--proto tcp-client" to a host that has IPv4+IPv6 in place, on an OS that will prefer IPv6 to IPv4 will always fail. The remote_list will have IPv6 in it's first entry, while the socket will try to do AF_INET, and that will not work. This will be fixed by the upcoming change to handle multiple remote IP addresses (as returned by getaddrinfo()) as multiple <connection> blocks, with appropriate retry and AF selection logic.

* Remove the ip-remote-hint option.Arne Schwabe2013-11-263-21/+2
| | | | | | | | | | | | | | | | | | | | | The ip-remote-hint option overrides the remote hostname of every remote/connection entry unless management-query-remote is also defined and the management interfaces overrides the option with remote MOD. The remote name is even overridden when when management interface issues remote ACCEPT after being presented with the non overridden remote. Overriding all remote options can also be done by management-query-remote and issuing remote MOD or by changing alll remote statements in the configuration.
