2013-05-21sulogin: allow system maintenance login if root password is emptyJonathan Liu
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>

2012-07-05include sys/resource.h where neededMike Frysinger
We use functions from sys/resource.h in misc applets, but don't include the header. This breaks building with newer glibc versions, so add the include where needed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
