[PATCH] v2v: Refactor some command line error messages.
by Richard W.M. Jones
This change (mostly) has no effect, except I changed the content of
two error messages to make them consistent with the others.

[PATCH] v2v: -o null: Force output format to be raw sparse.
by Richard W.M. Jones
When converting and throwing away the output (-o null), the input
format should not really matter. However it does currently matter for
a couple of reasons:
(1) If the input is not raw or qcow2, then you'll get the error below
because virt-v2v wants to write the same output format as input format
but only allows raw or qcow2 as output formats:
virt-v2v: error: output format should be 'raw' or 'qcow2'.
(2) If you use -o null -oa preallocated then a non-sparse temporary
disk is created before being deleted, but that just wastes disk space
for no reason.
Therefore this change
(i) prevents '-o null -oa preallocated' from being specified on the
command line,
(ii) prevents '-o null -of <anything>',
(iii) forces the output (temporary file) to be raw sparse.

Can I ask questions about libguestfs usage in SUSE linux ?
by Wang, Phoenix
Hi all,
Glad to join this mail list. As for project usage, we have to use libguestfs to mount guest image in SUSE Linux. While I see this mail list is in redhat, can I ask some question about libguest issue in SUSE ?
To be or not to be, that's the question.

[PATCH v4 0/9] Introducing virt-builder-repository
by Cédric Bosdonnat
Hi all,
Here is a v4 of my series. It includes the changes according to
Pino and Richard's comments.
However, the perrorf/debug problem is addressed differently:
instead of adding an implementation for the internal function
names when building for mllib, I redefine these macros. Obviously
this is not perfect, but at least easier to understand.
Pino's comment about the Notes regex wasn't quite right... thus
I added a unit test for the Index_parser.write_entry
As some more code has been moved around, the number of commits
in the series increased a little bit ;)
Cédric Bosdonnat (9):
lib/osinfo.c: Extract xml processing into a callback
lib: extract osinfo DB traversing API
mllib: ocaml wrapper for lib/osinfo
builder: rename docs test script
builder: add Index_parser.write_entry function
builder: add a template parameter to get_index
dib: move do_cp to mllib.Commun_utils
mllib: add do_mv helper function to Common_utils
Add a virt-builder-repository tool

[PATCH] v2v: Add extra tests for malformed OVA files.
by Richard W.M. Jones
Test:
- Bad SHA1 sum
- Bad SHA256 sum
- Invalid lines in manifest (x2)
- Good checksum and manifest
These tests were originally written by Tomáš Golembiovský. All I have
done is to integrate them into the virt-v2v test suite.

SECURITY: Various security issues in icoutils 'wrestool', used by libguestfs
by Richard W.M. Jones
Sorry for missing the importance of these earlier. These
vulnerabilities were first disclosed this January.
There are seven vulnerabilities reported in the icoutils package, in
the 'wrestool' program.
Unfortunately because libguestfs downloads untrusted guest content and
processes it with 'wrestool -x' on the host, libguestfs is vulnerable
to these. This could lead to host local code execution if you run
inspection tools (like virt-inspector) on untrusted guests or disk
images.
Virt-manager is also vulnerable if you have python-libguestfs
installed and are running any untrusted guests.
The suggested action is to immediately update icoutils to the
non-vulnerable version (at least 0.31.1).
* CVE-2017-5208 (wrestool):
When calling the guestfs_inspect_get_icon API to find the icon
associated with Windows XP or Windows 7 guests, libguestfs will run
'wrestool -x ...' on an untrusted file from the guest. wrestool could
be exploited to run local code on the host.
Note that any guest can "pretend" to look like Windows as far as
libguestfs inspection is concerned, so just because you don't have any
Windows guests does not help.
Original bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=850017
* CVE-2017-6009 (wrestool):
Also memory corruption in wrestool, could cause a crash and might be
exploitable in other ways. Original bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854050
* CVE-2017-6010, CVE-2017-6011 (both in wrestool):
Also memory corruption in wrestool, could cause a crash and might be
exploitable in other ways. Original bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854054
* CVE-2017-5331, CVE-2017-5332 and CVE-2017-5333 (all in wrestool):
These are also all local code execution bugs in wrestool and could be
exploited in the same way as above.

[PATCH] v2v: -o local: Check that UEFI firmware is installed before conversion.
by Richard W.M. Jones
Avoids a lengthy conversion followed by failure if we discover at the
end that OVMF is not installed.
This also changes the order of the methods in -o libvirt and -o qemu
so that it matches the order in the class interface, and also
logically makes more sense.
Partial fix for: https://bugzilla.redhat.com/show_bug.cgi?id=1429506
Thanks: Christopher Brown

[PATCH] lib: Prefer tirpc for XDR, and rationlise how we search for alternatives.
by Richard W.M. Jones
glibc in Fedora is currently configured with `--enable-obsolete-rpc',
so I guess we can see the way the wind is blowing.
(1) This changes our configure script to prefer libtirpc if it is
available.
If libtirpc is _not_ available then:
(a) Headers must be located in <rpc/xdr.h>, or the user must supply
the right CFLAGS.
(b) XDR functions must be located in one of -lportablexdr, -lrpc,
-lxdr, -lnsl or no library at all (ie. -lc), and the user must set
LDFLAGS if needed.
(2) We no longer add these paths automatically to $(CFLAGS)/$(LIBS).
Any part of libguestfs which needs <rpc/*.h> or the xdr_* functions
must use $(RPC_CFLAGS)/$(RPC_LIBS) explicitly.
(3) Previously Mac OS X had a workaround for the broken 64 bit support
in the supplied rpcgen. This workaround "activates" all the time if
you use tirpc, so breaking Linux after the above changes. tirpc is
supported on OS X, so I think it's just better to use that rather than
the broken rpcgen.
Thanks: Roy Keene
