* common: Improved the certificate information extračtionDavid Sommerseth2013-06-072-2/+88
| | | | | | | | | Added a function to extract the needed information from an OpenSSL X509 object. Also extended parse_tlsid() to include a pointer to the certificate digest, to have a common behaviour between parse_tlsid() and parse_x509_cert(). Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* common: Prepare for OpenVPN 2.3's new logging feature in plug-in API v3David Sommerseth2013-06-053-7/+42
| | | | | | | In OpenVPN v2.3 there's a new plug-in API with a more integrated log features. This patch prepares the logging infrastructure for this API. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* New feature: Added config option auth_disable_internalDavid Sommerseth2013-03-031-0/+1
| | | | | | | | | | | | By setting this config option in the eurephia database, eurephia will expect all user account/certificate links to be set up with an external plug-in for username/password authentications. Further, it is now ensured that system configuration issues or general failures not related to the user authentication itself, is not counted as a login attempt. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Added the first stab of an authentication plug-in frameworkDavid Sommerseth2013-03-032-2/+6
| | | | | | | | | This enables a run-time loadable support for other authentication modules. This can be used to make eurephia authenticate user's passwords against other sources than the local eurephia database itself. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* common: Added possibility to do dlsym() lookups as optional via ↵David Sommerseth2013-03-032-5/+22
| | | | | | | | eGetSym_optional() Will be used by the authentication plug-in framework. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>

* common: Fixed an error in the veurephia_log() macroDavid Sommerseth2011-07-261-1/+1
| | | | | | | The argument list didn't match what the internal _veurephia_log_func() function expected. This error was introduced in commit ebf4e80250b525e17 Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Moved generic parts of the config file parser to the common libraryDavid Sommerseth2011-07-253-0/+191
| | | | | | | Modified the eurephiadm client_config section to make use of the common version as well. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* common: Rework eurephia_log() to include also veurephia_log()David Sommerseth2011-07-252-11/+53
| | | | | | | veurephia_log() is to eurephia_log() what vprintf() is to printf(), taking va_list and const char *fmt arguments directly. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Look for endian.h in include/sys as well.David Sommerseth2010-12-311-1/+5
| | | | | | On FreeBSD the endian.h file is located in sys/endian.h. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Make use of more cross-platform friendly libc functionsDavid Sommerseth2010-12-311-3/+5
| | | | | | | | The initial implementation of the SHA512 hashing functions was tightly connected to glibc. This patch changes those few functions which is glibc to more portable functions. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Implemented proper TUN support in eurephiaDavid Sommerseth2010-12-141-0/+1
| | | | | | | | | | 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>
* Added a new eurephiaVALUES function: eClear_key_value()David Sommerseth2010-12-132-2/+16
| | | | | | | | This function clears the contents of a eurephiaVALUES key/value record. It will not remove the record from the stack, but only free the key and value pointers and sets them to NULL. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Implemented detection of OpenVPN tunnel device typeDavid Sommerseth2010-11-301-0/+9
| | | | | | | | | | | | 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>
* Discovered a failing loop checkDavid Sommerseth2010-09-271-1/+1
| | | | | | This could cause eurephia to use a faulty hashing rounds value. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Harden memory management in passwd.cDavid Sommerseth2010-09-271-0/+18
| | | | | | | Do a mlock() call on all buffers used by the password hashing algorithms, to make sure these data segments never will be written to swap. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Updated wrong log entriesDavid Sommerseth2010-08-291-1/+1
| | | | | | Removed old and obsolete expressions used to reference the eurephia database driver. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>

| * Improved file logging, providing source file and line number infoDavid Sommerseth2009-09-243-10/+24
| | | | | | | | | | Also changed malloc_nullsafe() and free_nullsafe() to report directly which file:line which called the malloc/free function.

| |
| * Rewritten the eurephia_log() to support syslog logging as wellDavid Sommerseth2009-09-243-46/+260
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* BUGFIX: saltlen was set to 0 when a buffer for a new salt was generatedDavid Sommerseth2009-09-151-12/+12
