The current password checking is unable to distinguish between the user entering an empty password or pressing Control-D. As a result, an empty password always results in normal startup. We modify bb_ask to return NULL if Control-D is pressed without entering a password. The sulogin applet is then modified to only proceed to normal startup if bb_ask returns NULL. This covers EOF with no password, interrupt by timeout and ^C. Signed-off-by: Jonathan Liu <net147@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
Please see the LICENSE file for copyright information (GPLv2) libbb is BusyBox's utility library. All of this stuff used to be stuffed into a single file named utility.c. When I split utility.c to create libbb, some of the very oldest stuff ended up without their original copyright and licensing information (which is now lost in the mists of time). If you see something that you wrote that is mis-attributed, do let me know so we can fix that up. Erik Andersen <andersen@codepoet.org>
