7dc8e24f0e ktest: Restore stty setting at first in dodie
The do_send_email() will call die before restoring stty if sendmail
setting is not correct or sendmail is not installed. It is safer to
restore it in the beginning of dodie().

4e7d2a8f0b ktest.pl: Add RUN_TIMEOUT option with default unlimited
There is a disconnect between the run_command function and the
wait_for_input. The wait_for_input has a default timeout of 2 minutes. But
if that happens, the run_command loop will exit out to the waitpid() of
the executing command. This fails in that it no longer monitors the
command, and also, the ssh to the test box can hang when its finished, as
it's waiting for the pipe it's writing to to flush, but the loop that
reads that pipe has already exited, leaving the command stuck, and the
test hangs.

Instead, make the default "wait_for_input" of the run_command infinite,
and allow the user to override it if they want with a default timeout
option "RUN_TIMEOUT".

But this fixes the hang that happens when the pipe is full and the ssh
session never exits.

83d29d439c ktest.pl: Give back console on Ctrt^C on monitor
When monitoring the console output, the stdout is being redirected to do
so. If Ctrl^C is hit during this mode, the stdout is not back to the
console, the user does not see anything they type (no echo).

Add "end_monitor" to the SIGINT interrupt handler to give back the console
on Ctrl^C.

e8bf9b98d4 ktest.pl: Fix missing "end_monitor" when machine check fails
In the "reboot" command, it does a check of the machine to see if it is
still alive with a simple "ssh echo" command. If it fails, it will assume
that a normal "ssh reboot" is not possible and force a power cycle.

In this case, the "start_monitor" is executed, but the "end_monitor" is
not, and this causes the screen will not be given back to the console. That
is, after the test, a "reset" command needs to be performed, as "echo" is
turned off.

26df05a8c1 kest.pl: Fix grub2 menu handling for rebooting
grub2 has submenus where to use grub-reboot, it requires:

  grub-reboot X>Y

where X is the main index and Y is the submenu. Thus if you have:

menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ...
	[...]
}
submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ...
        menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ...
                [...]
        }
        menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ...
		[...]
        }
        menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ...
                [...]
        }

And wanted to boot to the "Linux test" kernel, you need to run:

 # grub-reboot 1>2

As 1 is the second top menu (the submenu) and 2 is the third of the sub
menu entries.

Have the grub.cfg parsing for grub2 handle such cases.

ef784eebb5 ktest.pl minconfig: Unset configs instead of just removing them
After a full run of a make_min_config test, I noticed there were a lot of
CONFIGs still enabled that really should not be. Looking at them, I
noticed they were all defined as "default y". The issue is that the test
simple removes the config and re-runs make oldconfig, which enables it
again because it is set to default 'y'. Instead, explicitly disable the
config with writing "# CONFIG_FOO is not set" to the file to keep it from
being set again.

With this change, one of my box's minconfigs went from 768 configs set,
down to 521 configs set.

171ec346fc bootconfig/tracing/ktest: Add ktest examples of testing bootconfig
bootconfig is a new feature that appends scripts onto the initrd, and the
kernel executes the scripts as an extended kernel command line.

Need to add tests to test that the happened. To test the bootconfig
properly, the initrd needs to be updated and the kernel rebooted. ktest is
the perfect solution to perform these tests.

Add a example bootconfig.conf in the tools/testing/ktest/examples/include
and example bootconfig scripts in tools/testing/ktest/examples/bootconfig
and also include verifier scripts that ktest will install on the target
and run to make sure that the bootconfig options in the scripts took place
after the target rebooted with the new initrd update.

6a0f365295 ktest: Re-arrange the code blocks for better discoverability
Perl, as with most scripting languages, is fairly flexible in how /
where you can define things, and it will (for the most part) do what you
would expect it to do.  This however can lead to situations, like with
ktest, where things get muddled over time.

This pushes the variable definitions back up to the top, followed by
functions, with the main script executables down at the bottom, INSTEAD
of being somewhat mish-mashed together in certain places.  This mostly
has the advantage of making it more obvious where things are initially
defined, what functions are there, and ACTUALLY where the main script
starts executing, and should make this a little more approachable.

becdd17b5a ktest: Adding editor hints to improve consistency
Emacs and Vi(m) have different styles of dealing with perl syntax
which can lead to slightly inconsistent indentation, and makes the
code slightly harder to read.  Emacs assumes a more perl recommended
standard of 4 spaces (1 column) or tab (two column) indentation.

Vi(m) tends to favor just normal spaces or tabs depending on what
was being used.

This gives the basic hinting to Emacs and Vim to do what is
expected to be basically consistent.

Emacs:
	- Explicitly flip into perl mode, cperl would require
	  more adjustments

Vi(m):
	- Set softtabs=4 which will flip it over to doing
	  indentation the way you would expect from Emacs

If it fails to send email, then try again without the log file stating that

of email failed for some other reasons, but it will at least give the user

271e0c9dce ktest.pl: Fix incorrect reboot for grub2bls
This issue was first noticed when I was testing different kernels on
Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a
kernel entry was added successfully and the index of that kernel entry was
retrieved correctly, ktest still wouldn't reboot the system into
user-specified kernel.

The bug was spotted in subroutine reboot_to where the if-statement never
checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be
set for the next boot.

Add a check for "grub2bls" so that $grub_reboot $grub_number can
be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to
the correct kernel.

locations, and even though the test pass, there's things I want to look at
in the log file (like warnings). It is much easier to find where the log
file is, if it is displayed at the end of a test.

9dce29e65b ktest.pl: Have config-bisect save each config used in the bisect
When performing a automatic config bisect via ktest.pl, it is very useful to
have a copy of each of the bisects used. This way, if a bisect were to go
wrong, it is possible to retrace the steps and continue at the location
before the error was made.

The ktest.pl will make a copy of the good and bad configs, labeled as such,
as well as a number attached to it that represents the iteration of the
bisect. These files are saved in the ktest temp directory where it currently
stores the good and bad config files.

4d00fc477a ktest: Add timeout for ssh sync testing
Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.

Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.

791dc9d6b3 ktest: Make default build option oldconfig not randconfig
For the last time, I screwed up my ktest config file, and the build went
into the default "randconfig", blowing away the .config that I had set up.
The reason for the default randconfig was because when this was first
written, I wanted to do a bunch of randconfigs. But as time progressed,
ktest isn't about randconfig anymore, and because randconfig destroys the
config in the build directory, it's a dangerous default to have. Use
oldconfig as the default.

For BLS, kernel entry is added by kernel-install command through
POST_INSALL, for example,

POST_INSTALL = ssh root@Test "/usr/bin/kernel-install \
    add $KERNEL_VERSION /boot/vmlinuz-$KERNEL_VERSION"

The entry is removed by kernel-install command and the kernel
version is needed for the argument.

Pass KERNEL_VERSION variable to POST_KTEST so that kernel-install
command can remove the entry like as follows:

POST_KTEST = ssh root@Test "/usr/bin/kernel-install remove $KERNEL_VERSION"

37e1677330 ktest: introduce REBOOT_RETURN_CODE to confirm the result of REBOOT
Unexpected power cycle occurs while the installation of the
kernel.

   ssh root@Test sync ... [0 seconds] SUCCESS
   ssh root@Test reboot ... [1 second] FAILED!
   virsh destroy Test; sleep 5; virsh start Test ... [6 seconds] SUCCESS

That is because REBOOT, the default is "ssh $SSH_USER@$MACHINE
reboot", exits as 255 even if the reboot is successfully done,
like as:

   ]# ssh root@Test reboot
   Connection to Test closed by remote host.
   ]# echo $?
   255
   ]#

To avoid the unexpected power cycle, introduce a new parameter,
REBOOT_RETURN_CODE to judge whether REBOOT is successfully done
or not.
