Hello Chris,
1) is this on amd64?
Yes, this is on amd64.
2) which terminal is this? tty1 or something else?
What do you mean with "is this"? The error messages show up on tty1, the
default terminal I get when booting Debian without a GUI installed. The
one where it says "Debian GNU/Linux trixie/sid <hostname> tty1". But the
agetty process that crashes seems to be trying to manage a different tty
(see below).
3) whats your kernel command line?
# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-6.12.12-amd64
root=PARTUUID=add96c19-7043-4bb1-8899-ca970a7d33c8 ro console=tty0
console=ttyS0,115200 earlyprintk=ttyS0,115200 consoleblank=0
4) which image did you use exactly?
I can reproduce the error with today's image,
debian-13-generic-amd64-daily-20250223-2032.qcow2, without any
additional modifications. I'm running this on a Proxmox host.
5) could you try util-linux 2.41-rc1 from experimental?
I have just installed util-linux 2.41~rc1-1 and its dependencies and
rebooted the VM, didn't change anything, the error / segfault is still
present.
Attaching should be fine, possibly compressed. Probably an strace
log could be more insightful than the ltrace log.
I have attached both an ltrace and an strace log to this email.
Looks like commit 47831cc02ac0d71c335caecef1753f4c8861277c did not
take this into account fully. get_terminal_name resets *name to
NULL, and I think then op->tty ends up being NULL.
Yeah, that seems to be what happens. After I sent this bug report
yesterday, I also found out that someone has reported what I believe is
the same bug to upstream a while ago (
https://github.com/util-linux/util-linux/issues/3304 ) but so far nobody
has commented on that report.
Note that in the strace log I attached, it tries to open / access the
file at /run/credentials/serial-getty@ttyS0.service. My VM does not have
a serial port (since Proxmox VMs apparently don't have one by default).
If I add a serial port to the VM and then boot it, the errors are gone.
So maybe it tries to provide a serial console on ttyS0 due to the
"console=ttyS0,115200" in the kernel command line (I didn't put it
there, maybe it's the default?) and that fails because it doesn't exist?
If I run "cat /dev/ttyS0" on such a machine, I get "Input/output error".
When I add a serial port through proxmox (and the error is gone), the
"cat /dev/ttyS0" works (doesn't return because it's reading data).
So the issue seems to be related to a nonfunctioning serial port,
apparently.
Best regards,
Florian
