Hello Guix,

During 'guix system reconfigure' I got a kernel panic.

Getting it quite often while 'guix system reconfigure' at Linux magnolia
4.13.4-gnu #1 SMP 1 x86_64 GNU/Linux.  But it's not a subject of current
report.

After reboot I tried another attempt to make a 'guix system
reconfigure', but because of /etc/group.lock and /etc/passwd.lock
operating-system groups and users fields didn't applied.

I tried to get a creation of adbusers group and add my user to it, but
because of those files I cannot do it, until manually removed them.

So, do we need to check if *.lock files are exist and remove them at the
start of 'guix system reconfigure' OR abort reconfigure and creation of
Grub boot entry OR something else?

Thanks,
Oleg.

Kernel panic was caused by my miss configuring.  I used a Guile module
on reconfigure via GUILE_LOAD_PATH and (use-modles (my-module) in
config.scm.  I guess it's also required after reconfigure, according to
some times getting errors after reconfigure: cannot find my-module.  So
I need to add my-module globally on system.

Hello,

Oleg Pykhalov <go.wigust@HIDDEN> skribis:

> During 'guix system reconfigure' I got a kernel panic.

Can you show the exact command and its output?

A user-land program is not supposed to be able to cause a kernel panic;
if it does, that=E2=80=99s a kernel bug.

But perhaps you got the kernel panic *after* rebooting in the
reconfigured system?  That could well be a GuixSD bug, indeed.

I=E2=80=99m not sure I understand what happened.  Could you copy/paste comm=
ands
and outputs, or transcribe what happened?

TIA,
Ludo=E2=80=99.

Without seeing the config, I cannot tell whether it=E2=80=99s a bug on our =
side
or not.

However, if you=E2=80=99re confident that the bug is in your code, that=E2=
=80=99s good.
;-)  Should we close this bug?

Thanks,
Ludo=E2=80=99.

Hello Ludovic,

apologies for not adding logs before.  It's hard to do when I do guix
commands from Xterm and not from Emacs.  Emacs *shell* or *compilation*
buffers will eat all memory if they get too much text.

Probably need to redirect STDOUT STDERR in file when Xterm do guix.

I heard Guix folks work on implementing tiny log output to console and
redirect everything else to a log file.  This will be my life saver.

Sorry, as I said this is not a topic and I don't want to do it again and
I caution to make it on my current system.

I will setup a specific Guix VM for this, where I could make a 'system
reconfigure'.  Then I'll create a new bug report with full log.

Neverless I'll leave a how-to reproduce it below for at least for myself
TODO list.

The problem
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

The bigger problem from my view are files like /etc/group.lock and
/etc/passwd.lock.  For example:

    sudo touch /etc/group.lock

/etc/config.scm

    (operating-system
      ;; =E2=80=A6
      (groups (cons
         (user-group (name "test"))
         %base-groups)))

reconfigure log

The new system generation was produced without "test" group, so you
could reboot into it.  And it could lead to problems if we will have a
tiny output to console and big output to a log file, I guess.

                       How to make a kernel panic

The problem will be No defined variable IPTABLES-SSH after 'guix system
reconfigure' and kernel crash after.

$HOME/src/iptables/iptables/ru.scm

    (define-module (iptables ru)
      ;; =E2=80=A6
      )

    (define %iptables-ssh
       "-A INPUT -p tcp --dport 22 \
    -m state --state NEW -m recent --set --name SSH -j ACCEPT")

/etc/config.scm

    (use-modules ;; =E2=80=A6
                 (iptables ru))

    (define start-firewall
      #~(let ((iptables
               (lambda (str)
                 (zero? (system (string-join `(,#$(file-append iptables
                                                               "/sbin/iptab=
les")
                                               ,str) " "))))))
          (format #t "Install iptables rules.~%")
          (and
           ;; =E2=80=A6
           (iptables %iptables-ssh))))

    (define firewall-service
      (simple-service 'firewall shepherd-root-service-type
                      (list
                       (shepherd-service
                        (provision '(firewall))
                        (requirement '())
                        (start #~(lambda _
                                   #$start-firewall))
                        (respawn? #f)
                        (stop #~(lambda _
                                  (zero?
                                   (system* #$(file-append iptables
                                                           "/sbin/iptables")
                                            "-F"))))))))

    (operating-system
      ;; =E2=80=A6
        (services (cons* ;; =E2=80=A6
                         firewall-service)))

Make a kernel panic

    sudo GUILE_LOAD_PATH=3D\"$HOME/src/iptables\
    :$GUILE_LOAD_PATH\" guix system reconfigure \
    $HOME/dotfiles/guix/system-magnolia.scm

    # Run above again and kernel will panic.

> But perhaps you got the kernel panic *after* rebooting in the

No, it happens after second 'guix system reconfigure' with howto above.

[...]

Thanks,
Oleg.

I think we can avoid the problem by forcefully removing these two lock
files at boot time:

I tried to reproduce it with my user=E2=80=99s shepherd, but that didn=E2=
=80=99t work:

--8<---------------cut here---------------start------------->8---
ludo@ribbon ~/src/guix$ cat ,t.scm
(define s
  (make <service>
    #:provides '(nothing)
    #:start (lambda _ unbound)))

(register-services s)
(start s)
ludo@ribbon ~/src/guix$ herd load root ,t.scm
Loading ,t.scm.
herd: exception caught while executing 'load' on service 'root':

IOW, shepherd caught the exceptions and didn=E2=80=99t die.

What am I missing?

There is also a '/etc/.pwd.lock'.  Info about this file
https://lists.debian.org/debian-user/2005/07/msg02949.html


I'm not sure if any files are exist.  Days past after reconfigure
failure.

$ sudo find /etc -name '*.lock' # Shows nothing.

Hi!

Good idea.

<https://bugs.gnu.org/28647> is somewhat related.

Fundamentally though, to simplify this use case, we should have:

  (define (additional-udev-rules . rules)
    "Add RULES, a list of file-like object, as a udev rules."
    (simple-service 'udev-rule udev-service-type rules))

so one can write:

  (operating-system
     ;; =E2=80=A6
     (services (cons (additional-udev-rules %example-udev-rule)
                     %desktop-services)))

Thoughts?

Ludo=E2=80=99.

Hello Ludovic,

Apologies for the late reply.

Yes, I got an undefined %iptables-rst variable in reconfigure output

But at second run substitutions didn't work.  GuixSD rebuilds the world.
I didn't wait for this.

I also didn't make guix pull.

In my previous message I showed a way to (attempt to) reproduce the
problem by directly using =E2=80=98herd load=E2=80=99.

Could you try to reproduce the problem in this way?

You should even be able to check with a shepherd instance not running as
PID=C2=A01, which is more convenient.

Thanks in advance,
Ludo=E2=80=99.
