[PATCH 1/5] ktest: Add support for grub2

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 7497 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

As only grub or 'script' is supported for rebooting to a new kernel,
and Fedora 17 has dropped support for grub, I decided to add grub2
support as well (I also plan on adding syslinux/extlinux support too).

The options GRUB_FILE and GRUB_REBOOT were added to allow the user
to specify where to find the grub.cfg and what tool to use to reboot
into the next kernel respectively.

[PATCH 2/5] ktest: Sync before reboot

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 810 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Before rebooting the target, run the sync command, as it seems that
either Grub2 or systemd gets screwed up if you update to reboot a kernel
once and do a reboot without doing a sync.

[PATCH 3/5] ktest: Add native support for syslinux boot loader

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 5997 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

I installed Fedora 17 which no longer supports grub v1. I worked
with grub2 for a while, but there's so many issues with it and automated
rebooting, that I decided to switch to syslinux. Instead of using
the REBOOT_SCRIPT and add customized changes to get syslinux booted,
I thought it better to make ktest aware of syslinux and add options
to simplify the use of syslinux on a target test box.

[PATCH 4/5] ktest: Fix breakage from change of oldnoconfig to olddefconfig

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 1614 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Commit fb16d891 "kconfig: replace 'oldnoconfig' with 'olddefconfig', and
keep the old name", changed ktest's default config update from
oldnoconfig to olddefconfig without adding oldnoconfig as a backup.
The make oldnoconfig works much better than its backup of:
   yes '' | make oldconfig

But due to this change, and the fact that ktest is used to build lots of
older kernels (and for bisects), it forgoes the oldnoconfig completely.

[PATCH 5/5] ktest: Test if target machine is up before install

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 1492 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Sometimes a test kernel will crash or hang on reboot (this is even more
apparent when testing a config without CGROUPS on a box running
systemd). When this happens, on the next iteration of installing a
kernel, ktest will fail when it tries to install.

Have ktest do a check to see if the target can be connected to via ssh
before it tries to install. If it can't connect, then reboot again.
This time the reboot will fail because it can't connect and will force a
power cycle.

Just a bit disappointed that none of this made ever it into your for-next

Yeah, I know. That's because most of it stays in a quilt queue and I
commit it to git when the merge window opens. I use ktest every day, and
hammer it more than anyone else. I usually shake out all the bugs before
I post.

As this sits in the tools/testing/ktest/ directory and is just a single
perl script, it doesn't interact with other parts of the kernel tree.
I've been trying to remember to add it to linux-next, but sometimes I
forget :-(

My work flow with ktest is basically this:

1) Something about ktest bothers me

2) I write up a new feature

3) Test it a bit, and then make it into a quilt patch

4) After using it for a while, I'll do the git commit and push
   it off to linux-next

5) Merge window opens, I look at both my commits and my quilt queue
   and commit any missing patches that I feel is good enough

6) Push the entire thing off to Linus


ktest is very low on my priority list of things to maintain, and I
sometimes forget step 4. But I don't worry too much because it may miss
out on some testing, but if it breaks, it will only break ktest. It
shouldn't break anything else in the kernel.

And actually, I admit the last 3 patches of the series was written in
the last week and the other 2 a couple of weeks before that, as I was
adding a new machine to my test suite and added a Fedora 17 image for
the first time (first one without grub1 and with systemd), that it
caused me a lot of pain with my automated testing. I struggled with
grub2, got it mostly working, but then decided recently to just use
syslinux. I also just noticed the breakage that was there from the last
release, where the make oldnoconfig was changed. Hmm, maybe I should
look at linux-next more often, to see if anyone is touching ktest
without telling me.

I'll try to be better next time :-)  (no pun intended)

This makes sense, we should provide a backup for older kernels. Sorry
for not noticing the breakage.
