c45219c64f Added -q and -Q flags to shutdown command to make the "system is going down"
message appear less often. The -q flag causes messages to only appear at the
10 minute, 5 minute and x-hour intervals.
The -Q flag maintains complete silence up until the final "now" warning.

44fce86dde Added -l flag to "last" command. When used it allows "last" to
display usernames longer than 8 characters long.

be8e6b9e1c shutdown command was setting environment variable INIT_HALT to
"POWERDOWN", this should have been "POWERDOWN" as specified in the
manual page. Fixed code to match manual page and init scripts.

1b659c8ebe Applied patch from Daniel Povey which should allow killall5/pidof to
avoid locking up if it encounters stopped or zombie processes
due to broken NFS mount points.
This should allow Debian bug #719273 to be closed.

d27e34754a Unified shutdown and init to use 3 second wait between SIGTERM and
SIGKILL. Defined this value in init.h (WAIT_BETWEEN_SIGNALS) for
easy modification.
Updated documentation to address Debian bug #375274.

7b1d470949 Added check for kernel parameter init.autocon=1. If this exists, then
init will try to open its own console. If not, then any console=
parameters will be ignored. This avoids conflicts with native kernel
created consoles.

f1ca96e1c1 Added patch from Walter Harms which allows pidof to run without
displaying output. In this mode pidof simply returns true or false
without displaying PID values.

Updated manual page with new -q (quiet) mode.

Added -h flag for pidof, which was recognized before, but not used.
The -h flag now displays brief usage information for pidof.

6e8323e9fb The init process now writes the current runlevel to /var/run/runlevel.
This information can be read by the "runlevel" command as well as "halt"
and "reboot". Having the information logged in /var/run/runlevel as
well as the utmp file means systems without utmp (like those running
the musl C library) can still check the current runlevel. This is
useful when running halt/reboot as these programs want to check the
runlevel.

Updated the changelog, and manual pages for halt and runlevel.
2018-07-07 20:19:03 -03:00
Jesse Smith
6b26692584 Added new runlevel log code which saves (and reads) the current runlevel
from /var/run/runlevel. Added test code to runlevel.c to confirm it works.

Will use this to save/restore runlevel on systems where utmp is not
available.

that were flagged in comments or FIXME labels.

272f112c98 Added new signal handler for SIGUSR2. When init receives SIGUSR2
it closes (and leaves closed) the named pipe /run/initctl. This
can be used to make sure init does not have any files open. However,
it also means we cannot switch run levels or bring down the system.
The pipe can be re-opened by sending init the SIGUSR1 signal.

Updated the man pages for initctl and init to include this information.
2018-04-17 19:44:50 -03:00
Jesse Smith
f09da9cb55 Add check to make sure /run/initctl is open before we try to close
it when receiving SIGUSR1. Avoids crashing upon receiving signal.
2018-04-15 14:09:33 -03:00
Jesse Smith
aee28b3292 Updated init page to reference the initctl manual page instead of
telling people to read the source code to learn how to use
the /run/initctl named pipe. Updated Makefile to install
the initctl.5 manual page.

a4508479f5 Updated shutdown to check if time has lapsed when we did not
notice. For example if the computer was in sleep mode pending
a shutdown. The shutdown command now notices time has past
and adjusts its countdown clock to compensate. Accurate
to the nearest minute.
Closes Savannah bug #36279

d9b6475d85 Removed unneeded "count" variable in utmpdump.c.
Fixed typo in accidental wrote_wtmp_rlevel == 0 || wrote_wtmp_rlevel
comparison so the latter is wrote_utmp_rlevel.

Simplified logic in mountpoint.c when testing for same device or same inode.

Thanks to David Binderman for pointing out the above three issues.

Jesse Smith
8c8172349e Updated mountpoint to search for circular mount points when using
the -p parameter. This works around mountpoint not recognizing
circular mounts where /a/b/c/d and /a/b are the same location
(ie the same device and same inode).
Closes Savannah bug #37114.

986bee63c0 Allow multiple console output
When booting a kernel with multiple serial console support, or multuiple
console arguments ala "console=tty1 console=ttyS0,9600" the kernel will output
messages to all consoles, init however will not. It will only send output to,
and accept input from, the last of the consoles.
This patch fixes it.

80dbcf3de3 Moved the named communication pipe from /dev/initctl to /run/initctl. This
patch was supplied by Robert Millan from Debian. FreeBSD apparently does not
like named piped in /dev, so we move it to /run for better cross-platform
compatibility.

6e3e87bf32 Patch to automatically spawn agetty on kernel consoles
The feature is useful for developers and admins that occasionally need
to boot with e.g. console=ttyS0.
The built in default can be overridden via inittab for each device. An
entry like "S0::off:" turns off the getty on ttyS0.
