* Fix crash when using --inetd.Gert Doering2014-03-301-1/+1
| | | | | | | | | | | | | | | | | | Change "local" argument to socket_do_listen() to avoid calling "local->ai_addr" in the caller for the "do_listen == FALSE" case, in which case it could be NULL. Also, ensure "ai" is always initialized in socket_listen_accept() for the "!remote_dynamic" case - otherwise it will sometimes(!) crash in addrlist_match() later on. Get rid of spurious operator precedence warning concerning GETADDR_CACHE_MASK.

* Implement dual stack client support for OpenVPNArne Schwabe2013-11-291-39/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Schwabe2013-11-271-6/+70
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Instead of using the implicit protocol string that is returned by the proto/af to names function return a constant string. The strings have become part of the wire protocl and we do not want them to change if the printing of proto/af changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes to allow compilation with Microsoft Visual Studio 2008 * Fixed several instances of declarations after statements. * In socket.c, fixed issue where uninitialized value (err) is being passed to to gai_strerror. * ssl.c is trying to access multi_output_peer_info_env function in multi.c, causing an undefined symbol warning at compile time. ssl.c is strictly a client of multi.c (but not the other way around), therefore ssl.c does not include multi.h and should not depend on multi.h API. To fix, moved validate_peer_info_line and multi_output_peer_info_env from multi.c to misc.c. * MSVC doesn't support %z as a printf format specifier for size_t * MSVC doesn't support a const variable being used to dimension an array. * Explicitly cast the third parameter to setsockopt to const void * Acked-by: Gert Doering <gert@greenie.muc.de> Message-Id: <1375049135-21444-1-git-send-email-james@openvpn.net> URL: http://article.gmane.org/gmane.network.openvpn.devel/7777 Signed-off-by: Gert Doering <gert@greenie.muc.de>

* Merge getaddr_multi and getaddr6 into one functionArne Schwabe2012-09-021-11/+6
| | | | | | | | | | | | | | | | | | | the getaddr6 and getaddr_mutli functions are duplicates of each other. Since we always require getaddrinfo to be present both function are merge into one openvpn_getaddrinfo. This functions also returns a standard struct addrinfo* so our resolve interface is closer to the standard unix interface. The getaddr function is a wrapper which provides backward compatibility for IPv4 addresses. Ipv6 calls and calls to getaddr_multi are replaced with the new interface.
