* Mac OS X Keychain management clientVasily Kulikov2015-04-131-28/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for using certificates stored in the Mac OSX Keychain to authenticate with the OpenVPN server. This works with certificates stored on the computer as well as certificates on hardware tokens that support Apple's tokend interface. The patch is based on the Windows Crypto API certificate functionality that currently exists in OpenVPN. This patch version implements management client which handles RSA-SIGN command for RSA offloading. Also it handles new 'NEED-CERTIFICATE' request to pass a certificate from the keychain to OpenVPN. OpenVPN itself gets new 'NEED-CERTIFICATE" command which is called when --management-external-cert is used. It is implemented as a multiline command very similar to an existing 'RSA-SIGN' command. The patch is against commit 3341a98c2852d1d0c1eafdc70a3bdb218ec29049. v4: - added '--management-external-cert' argument - keychain-mcd now parses NEED-CERTIFICATE argument if 'auto' is passed as cmdline's identity template - fixed typo in help output option name - added '--management-external-cert' info in openvpn(8) manpage - added 'certificate' command documentation into doc/management-notes.txt v3: - used new 'NEED-CERTIFICATE' command for certificate data request instead of 'NEED-OK' - improved option checking - improved invalid certificate selection string handling - added man page for keychain-mcd - handle INFO, FATAL commands from openvpn and show them to user * ACK from Arne Schwabe for OpenVPN part * ACK from James based on Arne's testing v2 (http://sourceforge.net/p/openvpn/mailman/message/33225603/): - used management interface to communicate with OpenVPN process v1 (http://sourceforge.net/p/openvpn/mailman/message/33125844/): - used RSA_METHOD to extend openvpn itself Signed-off-by: Vasily Kulikov <segoon@openwall.com> -- Acked-by: Arne Schwabe <arne@rfc2549.org> Message-Id: <20150225160718.GA6306@cachalot> URL: http://article.gmane.org/gmane.network.openvpn.devel/9486 Signed-off-by: Gert Doering <gert@greenie.muc.de>
* Remove ENABLE_SSL define (and --disable-ssl configure option)Steffan Karger2014-12-311-2/+2
| | | | | | | | | | | | | | | | | | | Remove the --disable-ssl configure option and accompanying ENABLE_SSL defines in the master/2.4 branch, to reduce the code and testing complexity a bit. This does not remove to runtime option to run without SSL, just the compile time option to not include any SSL-related code. During the community meeting in November 2014 there were no objections amongst he developers present. Also, this has been announced on the -users and -devel mailing lists two weeks ago, without any response whatsoever.

* Workaround broken Android 4.4 VpnService API for persist-tun modeArne Schwabe2014-03-221-0/+28
| | | | | | | | | | | | | | | | In Android 4.4 it is not possible to open a new tun device and then close the old tun device without breaking the whole VPNService stack until the device is rebooted. Add new management method to ask the UI what method should be taken to ensure the optimal solution for the situation. Then do open-before-close or close-before-open inside open_tun() as requested.

* Implement dual stack client support for OpenVPNArne Schwabe2013-11-291-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Make push-peer-info visible in "normal" per-instance environment.Gert Doering2013-05-271-28/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, peer-info pushed by clients in the TLS handshake is only visible on the management interface, and only if --management-client-auth is enabled. With this patch, received records are sanitized and put into the normal "multi instance" environment, where it can be evaluated by --client-connect or --auth-user-pass-verify scripts and plugins, etc. Only records matching a fairly strict "name=value" format are accepted, and only names starting with IV_ or UV_ are exported, to avoid clients sending funny stuff and playing havoc with script/plugin environments on the server. In the "value" part, spaces, non-printable characters and shell metacharacters are replaced by '_'. The change is somewhat invasive as reception of the peer_info string was only done when username+password are expected from the client, but the data is always there (if the client sends no username/password, it will send 0-length strings, so always extracting 3 strings is safe). Also, the sanitation function validate_peer_info_line() and the opts->peer_info field were only compiled in #ifdef MANGEMENT_DEF_AUTH... Patch v3: do not call the old man_output_peer_info_env() anymore, unless a management env-filter has been set (= ensure IV_ and UV_ stuff is sent at most *once*, and exactly the way OpenVPN AS expects it). Add substituting of "bad" characters in the environment values.

* Avoid recursion in virtual_output_callback_func()David Sommerseth2012-11-291-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This solves a SEGV situation when using the management API while OpenVPN is closing down. The situation happens when the management socket has closed and OpenVPN tries to write an error about this to the management socket. What happens is that virtual_output_callback_func() is called, which then calls -> man_output_list_push_finalize() -> man_output_standalone() -> man_write() <-- this does the socket write -> man_io_error() -> x_msg() -> virtual_output_print() -> virtual_output_callback_func() (recursion start) virtual_output_callback_func() do have a mechanism to avoid recursion, but that did not keep the recurse counter when man_output_list_push_finalize() is called. This patch just reorganise the recursion block to also keep the counter while calling the other functions from virtual_output_callback_func() Signed-off-by: David Sommerseth <davids@redhat.com> Acked-by: Gert Doering <gert@greenie.muc.de> Message-Id: 1353063726-25113-1-git-send-email-dazo@users.sourceforge.net URL: http://article.gmane.org/gmane.network.openvpn.devel/7130
