df1aec8981 Accepted patch from Luc Gommans which explains why zombie and 
deep sleep processes (Z and D) may be hidden from pidof
 2019-05-25 15:41:57 -03:00
Jesse Smith
cc464b1189 Use millisecond delays in init so that shutdown 
can happen without a near-full-second delay after
all processes have terminated. Replaced do_sleep()
with do_msleep(), provided by Serge Belyshev.

Replaced hardwired sleep constants in init.c with
defined constants for easy updating in the future.

647ec365c6 Updated manual page for shutdown to better describe -h, -H and -P 
flags.

f1da344565 Dropped "-f" format flag for pidof command as it 
could be used to print information from memory or crash
pidof. Replaced flag with "-d" which allows for a custom
separator to be used between listed PIDs.
Patch supplied by KatolaZ.

4e2ad6a698 Fixed segfault in pidof when the -f (format) flag is used with 
crafted format strings.
Avoid printing stack memory when special format string is passed
to -f.
Listed control characters for -f flag in manual page.

aa3b8121e1 Fixed typo in init.8 manual page. 2019-02-17 21:51:13 -04:00
Jesse Smith
483dc777d2 Changed the way the "when" variable is used internally in shutdown.c. 
It starts as a NULL pointer, then might get set as a pointer to optarg,
then it might get set to point to an argv parameter, then it might have
a string value copied into it, over-writing the original data. We should
not risk over-writing internal variables which might get used for something
else (it's rude and security risk). Set up "when" as its own buffer
that has data from optargs and/or argv copied into it.

Minor code fixes across multiple source files to avoid buffer
overflows, or uninitialized strings.
 2019-01-27 15:55:08 -04:00
Jesse Smith
3f2b4a5704 Added logsave.c and logsave.8 manual page from e2fsprogs to make 
sure logsave is available to initscripts.

Updated src/Makefile to make sure bootlogd compiles with Clang.

5d955d55c8 Increased the size of the kernel command line buffer in bootlogd 
from 256 characters to 4096. This size is defined in KERNEL_COMMAND_LENGTH
for easy modification downstream.
 2018-12-29 14:46:10 -04:00

be8d584161 Added some defines and compile-time conditionals to make some 
components of sysvinit compile on FreeBSD.

cb0a849e87 Added patch to re-enable the omit flag (-o) in pidof. 2018-11-24 12:37:25 -04:00
Jesse Smith
f0e93128bc When the halt command is called with the -p flag (or as poweroff) 
the command now passes the "-h -P" flags to shutdown. This
in turn sets the INIT_HALT environment variable to POWEROFF.
Assuming this value is checked by initscripts during the
shutting down procedure, it should cause the system to
be powered off.
If halt is called without -p then the value of INIT_HALT
is not set and the default action (often set in /etc/defaut/halt)
is taken.
 2018-11-23 22:11:42 -04:00
Jesse Smith
c03e2fac2b Added fix to pidof which re-enabled the omit (-o) flag. 
this was broken when formatting was added in the 2.92 release.
Closes Debian bug #914494.

5b03e0faf0 Updated shutdown manual page to try to clarify which components 
of the shutdown process vs shutdown program we are referring to.
 2018-11-15 13:28:35 -04:00

f064d8f4b9 Added reference to readbootlog to the bootlogd manual page. This

prior to trying to install it.

848ee05104 Updated init manual page to include GRUB in boot loader comment 
as LILO is rarely used outside of the Slackware family these days.

Switched stty flags to use ECHOE instead of ECHOPRT. This should
give smoother, more natural backspac-erase behaviour on emergency
consoles. (Created in init -b mode.)

2fd897ff3a Fixed typo in changelog. 2018-11-01 22:06:14 -03:00
Jesse Smith
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.
 2018-11-01 17:21:47 -03:00
Jesse Smith
44fce86dde Added -l flag to "last" command. When used it allows "last" to 
display usernames longer than 8 characters long.
 2018-10-30 21:46:04 -03:00

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.

a17f736a42 Applied patch from Regid Ichira to clarify shutdown command 
line options. Updated manual page for shutdown.

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.
 2018-10-27 20:26:15 -03:00

b4f8539153 Addressed man page documentation to warn the halt -i flag may 
not properly shut down a network interface if it has no
valid IP address.

ed85143837 Removed super loud PC speaker beep during shutdown. 
Closes Debian bug #614893. Patch from Andreas Fackler.
 2018-10-22 22:03:09 -03:00
Jesse Smith
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.
 2018-10-22 21:44:39 -03:00
Jesse Smith
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.
 2018-09-29 17:12:12 -03:00
Jesse Smith
c29655a5c8 Updated changelog with information on pidof's new -q flag. 
Fixed Makefile to make sure it does proper clean before making
tarball. And properly creates signed tarball afterwards.
 2018-09-08 23:29:02 -03:00
Jesse Smith
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

7656f9d5f9 Version information is now fetched and defined by the Makefile.

e0cfd39728 Added "Fall through" comments to some switch statements where multiple 
approaches are tried in order to prevent warnings from GCC 7 (and newer).

Added includes on Linux for sys/sysmacros.h as the old defines in
the sys/types.h file will be removed in the future.
 2018-05-04 14:51:40 -03:00
Jesse Smith
cfb39b573f Updated init.c to remove some old notes and answer questions 
that were flagged in comments or FIXME labels.
 2018-04-23 00:09:49 -03:00
Jesse Smith
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
266671c968 Added documentation page for initctl (/run/initctl). 2018-04-08 22:03:07 -03:00
Jesse Smith
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
 2018-04-04 23:12:25 -03:00

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.

a436cdc993 Merge branch 'mountpoint' 2018-03-27 20:33:52 -03:00
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.

Jesse Smith
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.
