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.

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.

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.

5d3815b0ff Added manual page and options for readbootlog. 2018-11-12 20:53:52 -04:00
Jesse Smith
7c1a8d932a Added new tool (readbootlog) which will read the /var/log/boot file
produced by bootlogd. The output is displayed cleaned up so there
are no control characters. This avoids the need to use sed or related
tools to try to clean up the contents of the log.

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.)

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.

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.

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.

7656f9d5f9 Version information is now fetched and defined by the Makefile.
No more need to update the version manually in the init.c source.

bed25016b1 Updated sulogin.c to pull in crypt.h as it is a new, undocumented
dependency on Fedora 28.
Confirmed we can still build on other/older platforms.

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

cfb39b573f Updated init.c to remove some old notes and answer questions
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.

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.

2e1f87635e Removed extra sleep() calls from shutting down process since we use
sync() anyway to pause and make sure data is written out to disk.
