2017-04-13su: FEATURE_SU_BLANK_PW_NEEDS_SECURE_TTYDenys Vlasenko
When this feature is enabled, blank passwords are not accepted by su unless the user is on a secure TTY defined in /etc/securetty. This resembles the default PAM configuration of some Linux distros which specify the nullok_secure option for pam_unix.so. Based on patch by Kaarle Ritvanen <kaarle.ritvanen@datakunkku.fi> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2017-01-10Big cleanup in config help and descriptionDenys Vlasenko
Redundant help texts (one which only repeats the description) are deleted. Descriptions and help texts are trimmed. Some config options are moved, even across menus. No config option _names_ are changed. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

It is impossible to formulate sane ABI based on size of ulong because it can be 32-bit or 64-bit. Basically it means that you cannot portably use more that 32 option chars in one call anyway... Make it explicit.

2006-09-07getty, sulogin: convert to using bb_msg for syslog outputDenis Vlasenko
2006-08-03Remove bb_ prefixes from xfuncs.c (and a few other places), consolidateRob Landley
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only had one user), clean up lots of #includes... General cleanup pass. What I've been doing for the last couple days. And it conflicts! I've removed httpd.c from this checkin due to somebody else touching that file. It builds for me. I have to catch a bus. (Now you know why I'm looking forward to Mercurial.)
