* Add support of utun devices under Mac OS XArne Schwabe2013-07-031-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mac OS X 10.7+ natively supports tun devices (called utun). The "standard" utun.ko driver is sometimes problematic (e.g. VmWare Fusion 5 and tun.ko do not work together). When OpenVPN is compiled with utun support it will if no dev-node is given first try to use utun and if that is not available will try the traditional tun devices v2: Fixed tap support, get device name via ioctl, add manage v3.1: Fix compiling without if/utun.h, fix manage errors v4/v5: Don't try open to dynamically open utun0 -255 when early utun initialization fails, fix fallback to tun, give fatal error message when utun fails but no tun fallback should be done v6: add commit message change log, replace strstr with strncmp, move v7: Throw error if a user does the strange combination of --dev tun --dev-type tap and --dev-node utun A lot good input on earlier patches by Jonathan K.

* Added support for the Snappy compression algorithmJames Yonan2013-05-191-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added support for the Snappy compression algorithm which has shown to have considerably better compression speed than LZO at a comparable compression ratio. To enable Snappy add: compress snappy to both client and server config files. Alternatively, enable compression framing on the client: compress and have the server selectively push "compress snappy" to the client. This change also extends the client capability handshake to include IV_SNAPPY so the server can be aware that a connecting client supports Snappy. Note that the Snappy implementation also includes an improved framing approach where the first byte of the compressed payload is replaced by the compression control byte (the first payload byte is moved to the end of the packet). This solves off-by-one alignment issues, which improves performance on ARM. By default, the configure script will try to build with Snappy support. To disable, use the --disable-snappy option. The --enable-lzo-stub configure directive is now --enable-comp-stub (because it's not actually "lzo" but "compression-enabled packet framing") Add compression overhead to extra buffer unconditionally, as long as USE_COMP is defined.

* Remove the support for using system() when executing external programs or ↵David Sommerseth2012-10-311-16/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scripts This patch removes the support for the system() call, and enforces the usage of execve() on the *nix platform and CreateProcessW() on Windows. This is to enhance the overall security when calling external scripts. Using system() is prone to shell expansions, which may lead to security breaches. Which is also why the execve() approach has been the default since commit a82813527551f0e79c6d6ed5a9c1162e3c171bcf which re-introduced the system() in Nov. 2008. After having asked on the mailing list and checked around on the IRC channels, the genereal consensus is that very few uses system() these days. The only annoyance I've been made aware of is that this will now require adding a full path to the script interpreter together with the script, and not just put in the script name alone. But to just use the script name in Windows, you had to configure --script-security with the 'system' flag earlier too. So my conclusion is that it's better to add a full path to the script interpreter in Windows and raise the overal security with OpenVPN, than to continue to have a possible potentially risky OpenVPN configuration just to make life "easier" for Windows script users. Removal of the system() call, also solves a nasty bug related to the usage of putenv() on the *nix platforms.

* Add --compat-names optionHeiko Hund2012-09-121-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | With this option, users can basically undo the changes of the UTF-8 support commit 5e86fd93779482b90a191f929edebe414cd78a4f. It's here for short term compatibility and should be removed again as soon as possible. When OpenSSL is used, the subject strings will be in the proprietary format again. Generally username, X.509 CN, and X.509 subject will again be subject to '_' replacemant, unless the "no-remapping" flag is also specified. That flag ensures compatibility with setups using the --no-name-remapping option, that has been removed in 2.3.

| | | | | | | | | | | | | | | | | | This patch documents the usage of inline files in OpenVPN. Hackish ways of inline files are deliberately left out. For tls-auth and secret the key-direction option is right way of specifying the direction and not by using two tls-auth/secret lines where the first sets the direction and has a dummy file name and the second sets the inline file data but does not reset the direction parameter. Also pkcs12 [[INLINE]] base64encoded_data works but is a quirk of how the config parser works Signed-off-by: Arne Schwabe <arne@rfc2549.org> Acked-by: Gert Doering <gert@greenie.muc.de> Message-Id: 1345756860-2044-1-git-send-email-arne@rfc2549.org URL: http://article.gmane.org/gmane.network.openvpn.devel/7006 Signed-off-by: David Sommerseth <davids@redhat.com>
