The following will cause a segfault due to NULL being
passed to strcmp(3)
$ RC_SVCNAME=foo supervise-daemon
Fix the bounds check on argc in main. If argc<=1, then
it is not safe to dereference argv[1].
The statement
ll = strlen(applet);
appears twice in the same block without any
intervening assignment to the variables
'll' or 'applet'
Remove the second (duplicate) statement.
We have used /run for some time now and we have had this migration
script for 6 years. Linux users should have upgraded by now to a version
of OpenRC which stores its information in /run.
In order to run healthcheck() and the unhealthy() function, add an
exec_command call to the supervisor.
Another difference is This function also logs errors instead of
attempting to display them.
This is for #271.
I do not know of a need to have the default shell be a build-time
configurable setting. All *nix systems I am aware of have /bin/sh as a
default posix compatible shell.
If some systems running OpenRC do not make that assumption about
/bin/sh, I will consider bringing this back, so feel free to open an
issue.
Without a respawn period setting, the supervisor will give up on
respawning agetty after it is respawned respawn_max times. For most
daemons giving up like this is reasonable, but not for agettys. Agettys
should always be respawned unless they are respawning too fafst,.
If an agetty is respawning faster than 10 times in 60 seconds, this
seems to be too fast.
Since the pid file is internal to us, start moving toward deprecating it
by not requiring the user to specify it.
In the next release, I plan on working on code to start phasing out the
use of a pid file if this is possible.
This is needed in preparation for adding support for a fifo to allow us
to communicate with the supervisor to ask it to signal the child it is
supervising.
This reverts commit 2af0cedd59.
After speaking with Luis Ressel on the Gentoo selinux team, I am reverting
this commit for the following reasons:
- Luis told me that he feels this is not the solution we need to address
the concern with checkpath; I will be working with him on another
solution.
- There are concerns about the way the path variable was handled
and the assert() call.
The path variable should be dynamically allocated using xasprintf
instead of defining a length at compile time. This would eliminate the
need for the assert() call.
- It introduces the definition of _GNU_SOURCE which makes it
easier to introduce portability concerns in the future (see #262).
The pidfile of the supervisor doesn't need to be adjustable by the
service script. It is only used so the supervisor can stop itself when
the --stop option is used.
In start-stop-daemon and rc-schedules, we were printing out a warning if
the nanosleep call was interrupted by a signal, but we did not treat
this as an error situation other than displaying the message, so there
is no need for the message.
These services represent the parts of the keymaps and termencoding
services which saved the settings back to the root file system so they
can be loaded very early in the boot process.
These are needed to allow keymaps and termencoding to run earlier in the
boot sequence.

On Linux, kernel modules should be loaded once during boot, either in an
initramfs or by this service.
This does not change anything other than printing out messages if a
module is loaded more than once.

Health checks are a way to monitor a service and make sure it stays
healthy.
If a service is not healthy, it will be automatically restarted after
running the unhealthy() function to clean up.
