Title:
Kernel 4.4 NBD size overflow with image size exceeding 1TB
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Xenial:
Fix Committed
Bug description:
== SRU Justification ==
With the Xenial kernel, the bug reporter states there is an NBD size
overflow with image size exceeding 1TB.
There's an issue in kernel's NBD module which prevents some larger images to
be
correctly "connected" , largely described here:
https://github.com/NetworkBlockDevice/nbd/issues/44
This is a regression from Trusty and was fixed in mainline as of
v4.10-rc1.
== Fix ==
ef77b515243b ("nbd: use loff_t for blocksize and nbd_set_size args")
== Regression Potential ==
Medium. A backport was needed. However, it was due to some context
diffs and the way debugfs_create_u32 was used in Xenial and how
debugfs_create_u64 was used in the patch.
== Test Case ==
A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.
== Original Bug Report ==
Release 16.04, kernel 4.4.0-124-generic
There's an issue in kernel's NBD module which prevents some larger images to
be
correctly "connected" , largely described here:
https://github.com/NetworkBlockDevice/nbd/issues/44
There is a small patch here that was accepted into mainline 4.10:
https://www.spinics.net/lists/linux-block/msg07060.html
This is a regression from the previous LTS 3.13 kernel.
Here is a small example of the faulty behaviour:
# qemu-img create -f qcow2 test.img 1100G
Formatting 'test.img', fmt=qcow2 size=1181116006400 cluster_size=65536
lazy_refcounts=off refcount_bits=16
# qemu-nbd -c /dev/nbd0 test.img
# blockdev --getsize64 /dev/nbd0
18446743055802302464
The correct response would be 1181116006400; this breaks most tools
and makes the image unusable, e.g.
# fdisk -l /dev/nbd0
fdisk: cannot open /dev/nbd0: Invalid argument

apport information ** Tags added: apport-collected xenial ** Description changed: Release 16.04, kernel 4.4.0-124-generic There's an issue in kernel's NBD module which prevents some larger images to be correctly "connected" , largely described here: https://github.com/NetworkBlockDevice/nbd/issues/44 There is a small patch here that was accepted into mainline 4.10: https://www.spinics.net/lists/linux-block/msg07060.html This is a regression from the previous LTS 3.13 kernel.
