Package: src:linux
Version: 6.12.94-1
Severity: important
X-Debbugs-Cc: [email protected]
Hi,
I've spotted a regression regarding loop devices, starting with
v6.12.94. Going back to v6.12.90 makes the issue disappear.
I'm experiencing this issue in Debian 13 VMs that are used to build
Debian 13 system images (for amd64 and for arm64), and I'm able to
reproduce this bug by building two system images for amd64 on the same
host: the first build is fine but leaves the system in a corrupted
state, which breaks the second build (one safeguard detects the
label-based device matching finds more than 1 device, and bails).
I have yet to come up with a minimal reproducer, but I was able to find
ways to assess the “corrupted state” after the first build, without
starting the second build:
root@iot-isobuilder-52:~# fallocate -l 1G foo.img
root@iot-isobuilder-52:~# kpartx -asv foo.img
root@iot-isobuilder-52:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
loop0 7:0 0 1G 0 loop
├─loop0p1 259:0 0 487M 0 part
└─loop0p2 259:1 0 2.3G 0 part
sda 8:0 0 20G 0 disk
├─sda1 8:1 0 18.9G 0 part /
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 1.1G 0 part [SWAP]
root@iot-isobuilder-52:~# losetup
NAME SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE DIO LOG-SEC
/dev/loop0 0 0 0 0 /root/foo.img 0 512
The foo.img file doesn't exist in the first place, it is not getting
partitioned, and yet, we have both loop0p1 and loop0p2 coming up, with
sizes that match the system image built previously. Another hint is that
we have 259:0 and 259:1 as MAJ:MIN, instead of 253:0 and 253:1 when the
system image was being worked on.
Without toying with foo.img, on another system, after a single build,
while lsblk and losetup report nothing related to loop0, it's quite
clear that it's not been cleaned up properly:
root@iot-isobuilder-54:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 20G 0 disk
├─sda1 8:1 0 18.9G 0 part /
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 1.1G 0 part [SWAP]
root@iot-isobuilder-54:~# losetup
root@iot-isobuilder-54:~# find /sys/ -name loop0'*'|sort
/sys/block/loop0
/sys/class/block/loop0
/sys/class/block/loop0p1
/sys/class/block/loop0p2
/sys/devices/virtual/block/loop0
/sys/devices/virtual/block/loop0/loop0p1
/sys/devices/virtual/block/loop0/loop0p2
/sys/kernel/debug/block/loop0
(Going back to the older kernel confirms that loop0pX are absent there.)
Regarding the system image build, /dev/shm/system.img is allocated, then
fdisk, kpartx, mkfs.vfat, mkfs.ext4, debootstrap, apt, and finally
virt-sparsify are involved, but I haven't been able to reproduce the
problem without the debootstrap and apt steps. I'll follow up once I
have a small reproducer than my customer's image builds.
Looking at the changes between v6.12.90 and v6.12.94, the following one
seems pretty plausible:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3cef9aa17bf7dac59095b6972454c049a5fe97c0
backported from:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=267ec4d7223a783f029a980f41b93c39b17996da
From a quick look at loop.c in v6.12.94, the code mentioned in the
commit message looks like it's in place, so if the regression is
confirmed to come from this commit (which I'm not certain of yet), it
shouldn't be caused by assumptions valid in the master branch but not in
the stable branch.
Next steps for me (in no particular order):
- find a minimal reproducer;
- check what happens with a recent mainline kernel (e.g.
7.0.12-2~bpo13+1);
- check what happens with v6.12.94 once that commit is reverted.
Cheers,
