Title:
Xenial 32-bit: multipath exits with SIGSEGV
Status in multipath-tools package in Ubuntu:
Fix Released
Status in multipath-tools source package in Xenial:

Status in multipath-tools source package in Yakkety:

Bug description:
[Impact]
* The CLI for multipath segfaults when on 32-bit platforms.
* As example, a simple 'sudo multipathd -k"show paths"' will blow up,
assuming you have a multipath configured.
* The ultimate cause of the bug is the codebase not correctly dealing
with bit flags that have exceeded the 32-bit natural word size on
32-bit architectures. The fix has been cherrypicked from upstream.
[Test Case]
* You'll need to setup a 32-bit (e.g. i386) multipath environment to
test. I used qemu/kvm.
* See https://bugs.launchpad.net/ubuntu/+source/multipath-
tools/+bug/1611360/comments/4
* Once configured, type "sudo multipathd -k"show paths" and it will
fail with a segfault on 32-bit architectures, but succeed on 64-bit architectures.
[Regression Potential]
* Limited potential as only affects flag bits > 32-bits. In addition
to testing commands affected by these bits on 32-bit platform (i386),
I've regression tested that these commands work on 64-bit platform
(amd64).
