* *: Switch to POSIX utmpx APIBernhard Reutner-Fischer2015-04-021-2/+2
| | | | | | | | | | UTMP is SVID legacy, UTMPX is mandated by POSIX. Glibc and uClibc have identical layout of UTMP and UTMPX, both of these libc treat _PATH_UTMPX as _PATH_UTMP so from a user-perspective nothing changes except the names of the API entrypoints.

* init: do not fail build if SIGPWR is not definedMichael Tokarev2014-01-301-0/+2
| | | | | | | | | Apparently, some *BSD variants (and maybe some other OSes) does not define SIGPWR signal. So since commit 760fc6debcba8c, busybox fails to build on such platforms. Fix this. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* init: halt on SIGPWR tooBogdan Purcareata2013-11-261-3/+4
| | | | | | | | | | | | Most init processes implement a handler for SIGPWR that gracefully stops all child processes when shutting down a machine. Some other technologies rely on this signal - e.g. Busybox powered LXC containers. This patch makes busybox init halt when receiving SIGPWR.

| | | | | | | | | | | | | This feature was removed in 72c99af It is useful when process is removed from inittab and later added back, but never terminated. It prevents init from spawning duplicate. function old new delta check_delayed_sigs 176 182 +6 Signed-off-by: Paulius Zaleckas <paulius.zaleckas@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* init: don't use fixed size buffer for commandDenys Vlasenko2013-08-161-9/+13
| | | | | | | | | | | | | | | We store init actions forever. 256 bytes per action means that a typical inittab of ~10 commands uses 2.5k just to remember command strings - which are usually _much_ shorter than 256 bytes. At a cost of a bit more code, it's possible to allocate only actually needed amount. function old new delta init_exec 224 248 +24 new_init_action 140 142 +2 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
