(Updated Description/Summary)
Summary
==========
* This is a bug in the supermin package v5.1.14 in Xenial.
* This bug affects supermin versions < v5.1.18 when using a
kernel that is v4.13-based or later.
* This bug was caused by an update to the mainline v4.13 kernel
which broke supermin due to the way supermin handled symlinks.
Impact
========
* The bug results in total loss of functionality in supermin
and users of supermin such as guestfish, libguestfs-test-tool,
others. i.e. it is a regression in functionality for managing
virtual appliances.
* This bug does not affect Bionic, Artful or Trusty (See Comment #14).
Test Case & Reproduction
===========================
* This bug manifests in different ways based on the caller / use case
but is reliable and consistent in its reproduction.
See original description and Comment #12, for trivial repro cases.
Fix
====
* The fix for the Xenial version includes a backport of 2 upstream
fixes to the file ext2fs-c.c (the fix for the symlink breakage
is contained in this file). See comment #13 for details.
* A separate PPA test package for Xenial is available to test with
(See comment #13).
* This fix has been tested successfully on Xenial and shown to fix the
reported and related breakages as listed in this bug (Comment #12).
Regression Potential
=====================
* Regression Potential: there might be some bugs in some edge cases
that have not been tested or some environment that is not typical
causing some new issue which might affect the creation of the virtual
appliances and their management/manipulation via tools in the
libguestfs-tools package (e.g. guestfish).

package version supermin_5.1.14-2ubuntu1 to supermin_5.1.14-2ubuntu1.1.

[Impact]
An update to mainline kernel v4.13 breaks the supermin v5.1.14
package in Xenial. Supermin is a tool for preparing and building
very specific, tiny, virtual appliances which boot very fast. It
uses an ext2 file system disk image. Users of supermin functionality
like guestfish, libguestfs-test-tool, etc., all break in different
ways as a result, some catastrophic, but in each case, the tool
and virtual appliance are not usable. This impacts the
libguestfs-tools package (users of supermin).
This bug results in users not being able to upgrade their kernel,
specifically, use a kernel that is v4.13-based or later. A
workaround is to ensure that an earlier kernel (e.g. v4.4-based
Xenial kernels) is used by supermin. This can conflict
with user needs to use a later kernel for other reasons.
[Test Case]
1) Using the v5.1.14 supermin installed and running on a 4.13-based
kernel like 4.13.0-32-generic #35~16.04.1-Ubuntu:
(Assuming you have virtualization support packages etc. already
installed):
$ sudo apt-get install libguestfs-tools
$ libguestfs-test-tool
[appliance kernel panic or qemu crash or just a silent hang]
2) Using the v5.1.14 supermin version and running on a 4.13-based
kernel like 4.13.0-32-generic #35~16.04.1-Ubuntu:
# wget https://cloud-images.ubuntu.com/releases/16.04/release/ubuntu-16.04-server-cloudimg-amd64-disk1.img -O /var/lib/libvirt/images/ubuntu-16.04-server-cloudimg-amd64-disk1.img
# guestfish --rw -a /var/lib/libvirt/images/ubuntu-16.04-server-cloudimg-amd64-disk1.img
Welcome to guestfish, the guest filesystem shell for
editing virtual machine filesystems and disk images.
Type: 'help' for help on commands
'man' to read the manual
'quit' to quit the shell
><fs> run
libguestfs: error: appliance closed the connection unexpectedly.
This usually means the libguestfs appliance crashed.
[Regression Potential]
* There might be errors in creation and management of tiny
supermin appliances via tools in the libguestfs-tools
package.
[Other Info]
* From the upstream patch description, brief explanation of
the bug:
"The ext2 filesystem on disk format has two ways to store symlinks.
For symlinks >= 60 bytes in length, they are stored as files
(so-called "slow symlinks"). For shorter symlinks the symlink is
stored in the inode ("fast symlinks").
Previously we only created slow symlinks even if they are shorter than
60 bytes. This didn't matter until recently, when a change went into
the upstream kernel which assumes that symlinks shorter than 60 bytes
are always stored in the inode, thus breaking the filesystems that we
created before..."
Note that the real fix is to switch to use ext2fs_symlink() to create
links.
* A fix for this problem went into upstream supermin v5.1.18.
Thus this bug affects supermin < v5.1.18, and kernel >= v4.13.
* Thus this bug only affects the Ubuntu Xenial distro release:
supermin = v5.1.14
kernel = v4.13.*
Artful includes the v4.1.18 supermin package (which has the symlink fix)
and Bionic has a later one (v4.1.19). Thus neither is affected by
this issue. Trusty is running an older version (4.1.6-1) of supermin
but is not running the v4.13 or later kernel, and is thus not affected
either.
* This fix has been tested successfully on Xenial and shown to fix the
reported and related breakages as listed in the Test Case section
and more.
* A public PPA test package for Xenial is available to test with
and has been tested by at least one user who was seeing the
problem, successfully.
* This fix backports 2 patches from upstream:
1. ext2: Don't load whole files into memory when copying to the appliance (RHBZ#1113065).
2. ext2: Create symlinks properly (RHBZ#1470157).
Patch 1 is necessary as it supplies some dependent code
used by Patch 2; and Patch 2 does not compile cleanly without
it.
https://github.com/libguestfs/supermin/commit/158854e3ba4be7f6b8d81f662ddad98358ede1de
https://github.com/libguestfs/supermin/commit/f5a3deef588759c49dc862427a265aced612002d
Both patches are contained to a single file (ext2fs-c.c).
* The fixed supermin has been tested with older (< 4.13) kernels
as well, with no regression or issues.
* There is no security impact / aspect to this change (as confirmed
by a quick review from security team member)
