* eurephia-auth: Fixed a double-free situation with dev-type is not obviousDavid Sommerseth2012-10-111-3/+2
| | | | | | | | | | | | | | If OpenVPN is configured with a unkown --dev name and --dev-type is used, eurephia would in some specific situations double-free a memory region keeping the dev-type information. GETENV_*() functions returns a pointer to a buffer which is supposed to be free'd, but pointers returned by eGet_value() should not be free'd. And in the error situation if dev-type is not forced or detected, the memory allocated by GETENV_DEVNAME() was not properly free'd.

* Fix bug with TUN mode disconnects being logged wrongly.David Sommerseth2012-09-131-8/+0
| | | | | | | | | | This fixes a bug which appeared with newer OpenVPN versions, where the OPENVPN_PLUGIN_LEARN_ADDRESS would be called in the end - also in tun mode. And with the clean-up in session seed, in regards to the netmask not being part of the session seed, this little code made things worse. So lets get rid of it!

* eurephia-auth: eurephiaInit() may not always return a contextDavid Sommerseth2012-01-051-1/+4
| | | | | | Check if we have a context available before setting ctx->tuntype. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Implemented proper TUN support in eurephiaDavid Sommerseth2010-12-141-0/+8
| | | | | | | | | | Now eurephia will support both TUN and TAP configurations in OpenVPN. Thanks to Tavis Paquette and Matthew Gyurgyik for their willingness to test out this patch. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Implemented detection of OpenVPN tunnel device typeDavid Sommerseth2010-11-301-2/+88
| | | | | | | | | | | | This will later be used to be able to support OpenVPN in tun mode as well as the now only supported tap mode. It will first try to detect the tunnel type based on the 'dev_type' environment variable if available. If not, it will try to figure it out based on the device name. If this fails, it is possible to force the eurephia to a specific device type by setting the openvpn_devtype config variable. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Move daemonize() code to be called in the firewall child thread onlyDavid Sommerseth2010-11-261-30/+1
| | | | | | | | The eurephia plug-in would daemonize the OpenVPN process by calling daemonize() too early. This patch renames daemoinze() to efw_daemonize() and calls it only in the firewall child process. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>

* Use macros to extract values via get_env()David Sommerseth2009-10-051-2/+3
| | | | | This has two purposes. To make the code more readable and to use the same maximum length of the data being retrieved from the environment table.
* Modified get_env() function to limit number of bytes to extractDavid Sommerseth2009-10-021-3/+5
| | | | | This is to enhance the security and to avoid possible buffer overflows based on input received from the client
* Rewritten the eurephia_log() to support syslog logging as wellDavid Sommerseth2009-09-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | Also simplified the initialisation of the logging module. By calling the eurephia_log_init(eurephiaCTX *, char *dest, int loglevel) function, a log context will be setup inside the eurephiaCTX. To close the log file, eurephia_log_close(eurephiaCTX *) must be called. The destination string to eurephia_log_init() can be: - stdout: Log everything to stdout - stderr: Log everything to stderr - none: Do no logging at all - syslog:<facility> Log via syslog. <facility> can be: user, local[0-7], daemon or authpriv. - Filename All logging goes to the given filename. If the filename string is not recognised by any of the reserved words above, it will be handled as a filename.

* Cleaned up the code a little bitDavid Sommerseth2009-03-261-5/+4
| | | | | Made sure we only include needed include files and checked that the copyright headers are equal and correct
* Made eurephia_context.h even more generic and independentDavid Sommerseth2008-11-281-0/+3
| | | | | | | | | eurephia_context.h do only need to know about the eurephiaFWINTF * struct when compiling the auth plug-in and firewall modules. To enable this, EUREPHIA_FWINTF needs to be defined as well as the eurephiafw_struct.h must be included before including eurephia_context.h in the source. When this is not done, *fwcfg will just be a void *.
* Reorganised the source codeDavid Sommerseth2008-10-151-0/+179
Moved all OpenVPN plug-in related things into ./plugins, including firewall Moved all shared code into ./common and moved the generic part of the database files into ./database Updated all CMakeLists.txt files and created a new one for the root directory
