This patch resolves:
https://bugzilla.redhat.com/show_bug.cgi?id=889319
When assigning an SRIOV virtual function to a guest using "intelligent
PCI passthrough" (<interface type='hostdev'>, which sets the MAC
address and vlan tag of the VF before passing its info to qemu),
libvirt first learns the current MAC address and vlan tag by sending
an NLM_F_REQUEST message for the VF's PF (physical function) to the
kernel via a NETLINK_ROUTE socket (see virNetDevLinkDump()); the
response message's IFLA_VFINFO_LIST section is examined to extract the
info for the particular VF being assigned.
This worked fine with kernels up until kernel commit
115c9b81928360d769a76c632bae62d15206a94a (first appearing in upstream
kernel 3.3) which changed the ABI to not return IFLA_VFINFO_LIST in
the response until a newly introduced IFLA_EXT_MASK field was included
in the request, with the (newly introduced, of course) RTEXT_FILTER_VF
flag set.
The justification for this ABI change was that new fields had been
added to the VFINFO, causing NLM_F_REQUEST messages to fail on systems
with large numbers of VFs if the requesting application didn't have a
large enough buffer for all the info. The idea is that most
applications doing an NLM_F_REQUEST don't care about VFINFO anyway, so
eliminating it from the response would lower the requirements on
buffer size. Apparently, the people who pushed this patch made the
mistaken assumption that iproute2 (the "ip" command) was the only
package that used IFLA_VFINFO_LIST, so it wouldn't break anything else
(and they made sure that iproute2 was fixed.
The logic of this "fix" is debatable at best (one could claim that the
proper fix would be for the applications in question to be fixed so
that they properly sized the buffer, which is what libvirt does
(purely by virtue of using libnl), but it is what it is and we have to
deal with it.
In order for <interface type='hostdev'> to work properly on systems
with a kernel 3.3 or later, libvirt needs to add the afore-mentioned
IFLA_EXT_MASK field with RTEXT_FILTER_VF set.
Of course we also need to continue working on systems with older
kernels, so that one bit of code is compiled conditionally. The one
time this could cause problems is if the libvirt binary was built on a
system without IFLA_EXT_MASK which was subsequently updated to a
kernel that *did* have it. That could be solved by manually providing
the values of IFLA_EXT_MASK and RTEXT_FILTER_VF and adding it to the
message anyway, but I'm uncertain what that might actually do on a
system that didn't support the message, so for the time being we'll
just fail in that case (which will very likely never happen anyway).
This patch fixes the lack of error messages when libvirt fails to find
VFINFO in a returned netlinke response message.
https://bugzilla.redhat.com/show_bug.cgi?id=827519#c10 is an example
of the error message that was previously logged when the
IFLA_VFINFO_LIST object was missing from the netlink response. The
reason for this failure is detailed in
https://bugzilla.redhat.com/show_bug.cgi?id=889319
Even though that root problem has been fixed, the experience of
finding the root cause shows us how important it is to properly log an
error message in these cases. This patch *seems* to replace the entire
function, but really most of the changes are due to moving code that
was previously inside an if() statement out to the top level of the
function (the original if() was reversed and made to log an error and
return).
Revert the complex workaround of commit 39d91e9, now that we have
a nicer framework for shutting up broken gcc.
* src/util/buf.c (virBufferEscape): Simplify.
Commit 8b8fcdea introduced a check for broken gcc -Wlogical-op,
but did not guard the check against non-gcc compilers, which might
lead to spurious failures when another compiler encounters an
unknown pragma. Additionally, all of our compiler warning logic
should belong in a single file, and use cache variables to allow
overriding the decision at configure time if necessary.
* configure.ac (BROKEN_GCC_WLOGICALOP): Move...
* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): ...here,
and update to modern autoconf idioms.
When changing to virArch, the virt-aa-helper.c file was not
completely changed. The vahControl struct was left with a
char *arch field, instead of virArch arch field.
Historically there was an inconsistency in handling of the
itanium arch. The xen driver & CPU model code treated it
as 'ia64' but the QEMU capabilities code used 'itanium'. On
the grounds that no one has ever seriously used itanium
with QEMU, while RHEL shipped itanium with Xen, we should
favour 'ia64' as the canonical format
When parsing the arch from domain XML, the result was only
saved to a local variable, not the virDomainDefPtr

If securityselinuxtest was run on a system with newer SELinux
policy it would fail, due to using svirt_tcg_t instead of
svirt_t. Fixing the domain type to be KVM avoids this issue.
We can use VIR_REALLOC_N with NULL pointer, which behaves the same way
as VIR_ALLOC_N in that case, so no need for a condition that's
checking if some data are allocated already.
---
I tried to find other parts of the code similar to this, so I can do a
full cleanup for the whole repository, so I used this (excuse the long
line, but that's how I was writing it):
git grep -nHC 5 -e VIR_REALLOC_N -e VIR_ALLOC_N | while read line; do if [[ "$line" == "--" ]]; then if [[ ${#tmpbuf} -gt 10 && "$REALLOC_N" == "true" && "$ALLOC_N" == "true" ]]; then echo $line; while [[ ${#tmpbuf[*]} -gt 0 ]]; do echo "${tmpbuf[0]}"; tmpbuf=( "${tmpbuf[@]:1:${#tmpbuf[*]}}" ); done; fi; unset tmpbuf REALLOC_N ALLOC_N; else if [[ "$ALLOC_N" != "true" && "${line/VIR_ALLOC_N//}" != "${line}" ]]; then ALLOC_N="true"; fi; if [[ "$REALLOC_N" != "true" && "${line/VIR_REALLOC_N//}" != "${line}" ]]; then REALLOC_N="true"; fi; tmpbuf[${#tmpbuf[*]}]="$line"; fi; done | less
And reviewed the output just to find out this was the only occurrence of
the inconsistency.
On few places there are too many levels of indentation when some of
them can be fixed with negating the option they are in or omitting
useless condition altogether.
Unfortunately, rpm is stupid enough to bytycompile python scripts even
though they are located in /usr/share/doc/libvirt-python-*/examples and
it does so after %install phase is finished. Thus there's no way we
could remove those files from BUILDROOT. As a workaround, we may safely
remove the examples subdirectory completely without losing anything. The
python scripts that were installed there are also copied directly into
/usr/share/doc/libvirt-python-*/ by
%doc python/tests/*.py
rule. And yes, the files are actually tests, not examples.

This is yet another refinement to the fix for CVE-2012-3411:
https://bugzilla.redhat.com/show_bug.cgi?id=833033
It turns out that it would be very intrusive to correctly backport the
entire --bind-dynamic option to older dnsmasq versions
(e.g. dnsmasq-2.48 that is used on RHEL6.x and CentOS 6.x), but very
simple to patch those versions to just use SO_BINDTODEVICE on all
their listening sockets (SO_BINDTODEVICE also has the desired effect
of permitting only traffic that was received on the interface(s) where
dnsmasq was set to listen.)
This patch modifies the dnsmasq capabilities detection to detect the
string:
--bind-interfaces with SO_BINDTODEVICE
in the output of "dnsmasq --version", and in that case realize that
using the old --bind-interfaces option is just as safe as
--bind-dynamic (and therefore *not* forbid creation of networks that
use public IP address ranges).
If -bind-dynamic is available, it is still preferred over
--bind-interfaces.
Note that this patch does no harm in upstream, or in any distro's
downstream if it happens to end up there, but builds for distros that
have a new enough dnsmasq to support --bind-dynamic do *NOT* need to
specifically backport this patch; it's only required for distro
releases that have dnsmasq too old to have --bind-dynamic (and those
distros will need to add the SO_BINDTODEVICE patch to dnsmasq,
*including the extra string in the --version output*, as well.
Using s/#authorslist#/$$out/ makes perl eat @domain part of all email
addresses from $out since it tries to interpret them as array variables.
I'm not sure if we can escape those in s/// but I know we can use print:
s/#authorslist#// and print '$$out'
to tell perl not to even look inside $out.
This patch also fixes gen-AUTHORS so that it works in VPATH.
Somehow I managed to push the changes to this file with improper
indentation. This patch just re-indents, reformats the comment lines,
and re-groups a couple of multi-line strings so that they fit within
80 columns. The resulting binary should be identical.
There's been a few bugs about an expected error from polkit:
https://bugzilla.redhat.com/show_bug.cgi?id=873799https://bugzilla.redhat.com/show_bug.cgi?id=872166
The error is:
Authorization requires authentication but no agent is available.
The error means that polkit needs a password, but there is no polkit
agent registered in your session. Polkit agents are the bit of UI that
pop up and actually ask for your password.
Preface the error with the string 'polkit:' so folks can hopefully
make more sense of it.
