* Replace strdup() calls for string_alloc() callsSteffan Karger2015-10-041-1/+1
| | | | | | | | | | | | As reported by Bill Parker in trac #600, strdup() return values are not always correctly checked for failed allocations. This patch adds missing checks by using string_alloc(), which performs the required checks.

* Fix commit e473b7c if an inline file happens to have a line break exactly at ↵Arne Schwabe2015-07-271-1/+4
| | | | | | | | | | | | | | | buffer limit The check does only for strlen(line) space and buf_printf will only use at most space -1 and not print the final character ('\n') in this corner. Since a missing \n only breaks certificates at the start and end marker, missing line breaks otherwise do not trigger this error.

* Mac OS X Keychain management clientVasily Kulikov2015-04-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Support UTF-8 --client-config-dirHeiko Hund2012-10-291-0/+5
| | | | | | | | | | | | | | | | | | | If a common name (or user name, when used in conjunction with --username-as-common-name) contains UTF-8 encoded characters their octets get replaced by underscores. This becomes problematic when user "Müller" and "Möller" need to have a CCD file and both would receive options from the file "M__ller". The situation is even worse for non-latin alphabets, where CCD file names consist of underscores entirely. This patch removes that limitation and also allows the file names to contain any punctuation characters besided the resevered ones.
