Subject: [PATCH 1/6] copy: Stable sort in tests.
When running the tests in Koji they behaved differently from running
locally (under a UTF-8 locale). This turned out to be a difference in
sorting under the different locales.
Thanks: Eric Blake

Now that we finally have a CVE number, it's time to document
the problem (it's low severity, but still a denial of service).

Subject: [PATCH 3/6] Revert "copy: file-ops.c: Remove unneeded check"
This reverts commit 0f6e4f38bc440fc52c20a3a448ef031f806ec5e2.
This fails on ppc64le only with:
lt-nbdcopy: file-ops.c:136: page_was_cached: Assertion `page < rwf->cached_pages.size' failed.
Coincidentally this is the only architecture on Fedora that uses a 64K
page size, although I don't know if that is connected. I was not able
to make this fail on x86.

Subject: [PATCH 5/6] copy/file-ops.c: Fix page eviction when len < page_size.
On Fedora ppc64le at the moment page size is 64K. When asked to evict
a range with length < 64K the length calculation wrapped around and it
tried to evict a huge number of pages beyond the end of the file.
With Nir's commit 0f6e4f38b this (correctly) resulted in an assertion
failure.
Fix this by checking for the overflow and returning early.

From 64962a582c00828cc2d26d94b149840ab2402165 Mon Sep 17 00:00:00 2001
From: Eric Blake <eblake@redhat.com>

Subject: [PATCH 6/6] info: Let exit status reflect any failures during
NBD_OPT_INFO
It turns out that at least nbdkit's testsuite was relying on a
non-zero exit status from nbdinfo when purposefully attempting to get
info on an invalid export name. Printing as much information as
possible instead of going silent becaus of one error is good, but any
time we print to stderr, the exit status should reflect that.
Fixes: 5473e34fc1 (info: Don't kill --list early just because one opt_info fails)
Reported-by: Rich Jones <rjones@redhat.com>
