2014-11-21init: add a minimalist init programJustus Winter
This patch adds a minimalist init program. It is somewhat lacking in features, but is able to bring up a Hurd system with the runsystem and rc scripts. In fact, it roughly does what the former /hurd/init did, modulo all the very early bootstrapping stuff and the startup protocol. It is started when all the essential servers are up and running, so it can make use of most of the POSIX goodies, making its implementation much simpler. * Makefile (prog-subdirs): Add init. * daemons/runsystem.sh: Generalize runsystem so that it can start any init as specified on the kernel command line. By default, it starts /hurd/init. * daemons/runsystem.hurd: This is a verbatim copy of runsystem.sh. It is started by /hurd/init. * daemons/rc.sh: Do not start /hurd/mach-defpager as it is already started in runsystem.sh. * daemons/Makefile (SRCS): Add runsystem.hurd. * init/Makefile: New file. * init/init.c: Likewise.
2014-11-21startup: rename /hurd/init to /hurd/startupJustus Winter
This patch series splits /hurd/init into two programs. As a first step, this patch renames /hurd/init to /hurd/startup. It is called startup because it speaks the startup protocol. * startup: Rename init to startup. Adjust accordingly. * Makefile (prog-subdirs): Likewise. * doc/hurd.texi (Server Bootstrap): Likewise. * hurd/paths.h (_HURD_STARTUP): Likewise. * libdiskfs/boot-start.c (diskfs_boot_init_program): Likewise. * libdiskfs/opts-std-startup.c (startup_options): Likewise.
2014-11-21Add proc_set_init_task, make runsystem pid 1Justus Winter
* hurd/process.defs (proc_set_init_task): New procedure. * hurd/process_reply.defs (proc_set_init_task): Likewise. * hurd/process_request.defs (proc_set_init_task): Likewise. * include/pids.h: Add HURD_PID_INIT as 1, adjust others accordingly. * init/init.c (start_child): Register the child task. * proc/proc.h (init_proc): New variable. (create_startup_proc): Rename to create_init_proc. * proc/main.c (main): Create placeholder proc object for pid 1. * proc/mgt.c: Use init_proc instead of startup_proc, as the former is the new root of the process tree. (create_startup_proc): Rename to create_init_proc. (S_proc_set_init_task): New function. * doc/hurd.texi (Server Bootstrap): Update accordingly. * procfs/main.c: Do not hard-code kernel pid, use pids.h instead.

2013-08-29init: Mark all of inits children and init itself as importantJustus Winter
This is based on a fragment of Guillem Jovers patch presented here: http://lists.gnu.org/archive/html/bug-hurd/2006-02/msg00081.html It has been refreshed, updated and the copyright year is adjusted properly. It has been complemented with the necessary features to address the issues the original patch set out to address, namely that killall5 freezes the proc translator before it tries to walk over /proc/*/stat to decide which process to kill. Prior to this patch (and the one marking the procfs server as important process), killall5 would deadlock trying to walk over the proc file system. Ironically it would not have killed any process later on even if it had the chance, since two values obtained from /proc/*/stat are currently hardcoded to zero in our procfs. Patches addressing the problem as a whole are prepared and will be sent as a follow up. * init/init.c (launch_core_servers): Mark init, auth, proc and fs servers as important. (start_child): Mark the real init as important. (S_startup_important_task): Mark exec server as important.
