2003-04-24There have been many reports of init failing to reboot and/or failing to haltEric Andersen
over the years. Well I finally took the time to track this down. It turns out that inside linux/kernel/sys.c the kernel will call machine_halt(); do_exit(0); when halting, or will call machine_power_off(); do_exit(0); during a reboot. Unlike sysv init, we call reboot from within the init process, so if the call to machine_halt() or machine_power_off() returns, the call to do_exit(0) will cause the kernel to panic. Which is a very bad thing to happen. So I just added this little patch to fork and call the reboot syscall from within the forked child process, thereby neatly avoiding the problem. But IMHO, both calls to do_exit(0) within linux/kernel/sys.c are bugs and should be fixed. -Erik

2002-12-17Odd. I never brought this forward from bb.stable. Should handleEric Andersen
reaping child processes better. -Erik
2002-11-28Use error_msg instead of fprintf(stderrGlenn L McGrath
2002-10-22I committed the fflush in the wrong spot. I should go to bedEric Andersen
earlier so I don't screw up such easy stuff. -Erik
2002-10-22Be absurdly careful about flushing stdout.Eric Andersen
2002-10-12After thinking about it, I think this patch from Matt Kraai is probably theEric Andersen
best way to go. Sysvinit does not provide a controlling tty since it doesn't even try to open ttys for apps. We do. So we should _try_ to provide a controlling tty if possible, but we needn't freak out if it doesn't work. This way we won't need to use openvt or similar, we'll just have init do the Right Thing(tm).
2002-10-10last_patch61 from vodz:Eric Andersen
New complex patch for decrease size devel version. Requires previous patch. Also removed small problems from dutmp and tar applets. Also includes vodz' last_patch61_2: Last patch correcting comment for #endif and more integrated with libbb (very reduce size if used "cat" applet also). Requires last_patch61 for modutils/config.in.

2002-09-25Ignoring SIGCHLD causes a race leading to the occasional hang of initEric Andersen
when init will wait() on itself in waitfor() when the child exits before init is scheduled to run. Letting init hang is very seriously bad. -Erik

2002-07-29Kill a silly warningEric Andersen
2002-07-29Patch from Tim Riker to allow tty* in inittab if the ttyEric Andersen
actually exists -- serial console is not the issue...
2002-07-03This is last_patch48 from vodz. More cleanups, kills a bitEric Andersen
of dead code, fixes one blatent bug.
2002-07-03Apply last_patch47 from vodz to fix several problems, such as the ash "jobEric Andersen
control turned off" bug, console_setup() was called with a closed file descriptor, setsid() inconsistancy, and silly string handling bugs. I have modified his patch to allow the askfirst init actions to have a controlling terminal.

2001-09-05Two patches from Magick <magick@linux-fan.com>:Eric Andersen
1st makes init smaller, and fixes a bug with AskFirst. Reading from /dev/null gives EOF. 2nd makes init run the command's in the order of inittab, as in FIFO instead of LIFO.
2001-07-23Add support for devfs device names.Matt Kraai
2001-07-22Some patches to make dietlibc work...Eric Andersen

2001-04-25Move messages.c to libbb. Make each string in messages.c be its own .o file.Eric Andersen
This way, we can new get rid of all that tedious #define rubbish we used to need to enable specific messages. This way is enormously simpler, and as a bonus also ends up saving us 96 bytes. -Erik
2001-04-23A patch from Marc Karasek and Kanoj (kernel serial.c maintainer)Eric Andersen
so init will work on serial consoles with 2.4.3+ kernels, thanks to Fabrice Gautier <gautier@email.enst.fr> for finding this one. -Erik
