* Fix parameter listing in non-debug builds at verb 4Josh Cepek2013-03-145-11/+11
| | | | | | | | | | | | | | | | | | | | | | | When built with enable_debug=no, the parameter output expected at --verb 4 is not printed due to use of #ifdef ENABLE_DEBUG in the responsible code sections. This appears to be a mistake when looking at the configure help text for enable_small and enable_debug. This change keys the relevant code off of enable_small instead, including the parameter listing when enale_small=no (the configure-script default.) Most of this code is in options.c, with some callers present in plugin.c/h and route.c/h. No function code is changed, just the #ifdef values to use the small feature instead of debug. This means builds no longer need enable_debug=yes in order to get the expected log output at verb 4.

* Repair "tcp server queue overflow" brokenness, more <stdbool.h> fallout.Gert Doering2013-03-121-1/+1
| | | | | | | | | | | | | | | | Return value of mbuf_len() wrong - it's returning a length value, not a yes/no value - so when the queue length approached 65 (full!), it still only returned "1", leading to MBUF overflow later on. Change from "bool" to "unsigned int", misbehaviour gone... This fixes OpenVPN trac ticket #263.

* Fix corner case in NTLM authentication (trac #172)Christian Niessner2013-03-071-2/+2
| | | | | | | | | | | | | | | | | The problem is located in the file proxy.c within "establish_http_proxy_passthru": To keep buffers small long base64-encoded NTLM-Strings are truncated. But the truncating is done on a wrong place: base 64 strings can be cut every 4 chars. the buffer is 128 bytes - including the terminating \0, so the usable data is only 127 bytes. And decoding a 127 char base64 string fails... this is why the ntlm authentication fails in certain cases (long strings)...

* Ignore UTF-8 byte order markHeiko Hund2013-02-061-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently openvpn exits when reading configuration from a file that has an UTF-8 byte order mark (EF BB BF) at its start. While it is useless to put a BOM into UTF-8 encoded files, the Unicode standard [1] permits it (on page 36): "Use of a BOM is neither required nor recommended for UTF-8, but may be encountered in contexts where UTF-8 data is converted from other encoding forms that use a BOM or where the BOM is used as a UTF-8 signature." Notepad.exe, the default text editor on Windows, always puts the BOM into UTF-8 encoded files when saving them. Others may do as well. Just ignoring the UTF-8 BOM will make config files with UTF-8 BOM readable.

* 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.

* Remove the support for using system() when executing external programs or ↵David Sommerseth2012-10-317-223/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The situation is even worse for non-latin alphabets, where CCD file names consist of underscores entirely.

| | | | | | | | | | | | | | | | There's a small implementation issue with the V3 plugin API implementation. V3 plugins cannot return data back to OpenVPN using openvpn_plugin_args_func_return since openvpn_plugin_args_func_return.return_list is always NULL. This patch makes the behaviour identical to the V2 API (return_list is again a proper out parameter).

* Add --compat-names optionHeiko Hund2012-09-125-9/+94
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix reconnect issues when --push and UDP is used on the serverDavid Sommerseth2012-09-112-3/+6
| | | | | | | | | | | | | | | | | | | | | When the server is configured with UDP and --push statements, reconnecting often fails by the client never receiving PUSH_REPLY. The client sends PUSH_REQUEST and the server logs these requests but does not send them. This bug got introduced in commit ff65da3a230b658b2c1d52dc1a48612e80a2eb42 which tries to avoid sending duplicated PUSH messages if the client/server connection is slow. This patch keeps this behaviour, but instead of a session wide PUSH_REPLY block it sets an expiry time for the PUSH_REPLY block. The expiry time is set to 30 seconds.
