Adam Williamson e698b1d369 Change the %post fix to match upstream
Upstream fixed this by making the %post scriptlet use
%with_firewalld_zone rather than making the BuildRequires use
%with_firewalld, so let's follow that.

Adam Williamson 97d2066b3e Fix scriptlet error when built without firewalld zone support
In 5cbc0451, Daniel added a use of the %firewalld_reload macro
that's conditional on `with_firewalld`, but made the BuildRequire
on firewalld-filesystem (which provides the macro) conditional
on `with_firewalld_zone`. So if you build without firewalld_zone
but with firewalld, the macro is not expanded and the built
package has a broken %post script. This fixes it by making the
BuildRequire also conditional on `with_firewalld`.

Subject: [PATCH] build: support explicitly disabling netcf
placing "-Dnetcf=disabled" on the meson commandline was ignored,
meaning that even with that option the build would get WITH_NETCF if
the netcf-devel package was found - the only way to disable it was to
uninstall netcf-devel.
This patch adds the small bit of logic to check the netcf meson
commandline option (in addition to whether netcf-devel is installed)
before defining WITH_NETCF.

Subject: [PATCH] storage: split off code for calling rbd_list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The rbd_list method has a quite unpleasant signature returning an
array of strings in a single buffer instead of an array. It is
being deprecated in favour of rbd_list2. To maintain clarity of
code when supporting both APIs in parallel, split the rbd_list
code out into a separate method.
In splitting this we now honour the rbd_list failures.

Subject: [PATCH] network: improve error report when firewall chain creation
fails
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
During startup we create some top level chains in which all
virtual network firewall rules will be placed. The upfront
creation is done to avoid slowing down creation of individual
virtual networks by checking for chain existance every time.
There are some factors which can cause this upfront creation
to fail and while a message will get into the libvirtd log
this won't be seen by users who later try to start a virtual
network. Instead they'll just get a message saying that the
libvirt top level chain does not exist. This message is
accurate, but unhelpful for solving the root cause.
This patch thus saves any error during daemon startup and
reports it when trying to create a virtual network later.

Subject: [PATCH] virSetUIDGIDWithCaps: Don't drop CAP_SETPCAP right away
There are few cases where we execute a virCommand with all caps
cleared (virCommandClearCaps()). For instance
dnsmasqCapsRefreshInternal() does just that. This means, that
after fork() and before exec() the virSetUIDGIDWithCaps() is
called. But since the caller did not want to change anything,
just drop capabilities, these are the values of arguments:
virSetUIDGIDWithCaps (uid=-1, gid=-1, groups=0x0, ngroups=0,
capBits=0, clearExistingCaps=true)
This means that indeed all capabilities will be dropped,
including CAP_SETPCAP. But this capability controls whether
capabilities can be set, IOW whether capng_apply() succeeds.
There are two calls of capng_apply() in the function. The
CAP_SETPCAP is dropped after the first call and thus the other
call (capng_apply(CAPNG_SELECT_BOUNDS);) fails.
The solution is to keep the capability for as long as needed
(just like CAP_SETGID and CAP_SETUID) and drop it only at the
very end (just like CAP_SETGID and CAP_SETUID).

Subject: [PATCH] network: split setup of ipv4 and ipv6 top level chains
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
During startup libvirtd creates top level chains for both ipv4
and ipv6 protocols. If this fails for any reason then startup
of virtual networks is blocked.
The default virtual network, however, only requires use of ipv4
and some servers have ipv6 disabled so it is expected that ipv6
chain creation will fail. There could equally be servers with
no ipv4, only ipv6.
This patch thus makes error reporting a little more fine grained
so that it works more sensibly when either ipv4 or ipv6 is
disabled on the server. Only the protocols that are actually
used by the virtual network have errors reported.

A process can access a file if the set of MCS categories
for the file is equal-to *or* a subset-of, the set of
MCS categories for the process.
If there are two VMs:
a) svirt_t:s0:c117
b) svirt_t:s0:c117,c720
Then VM (b) is able to access files labelled for VM (a).
IOW, we must discard case where the categories are equal
because that is a subset of many other valid category pairs.

Subject: [PATCH] network: avoid trying to create global firewall rules if
unprivileged
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The unprivileged libvirtd does not have permission to create firewall
rules, or bridge devices, or do anything to the host network in
general. Historically we still activate the network driver though and
let the network start API call fail.
The startup code path which reloads firewall rules on active networks
would thus effectively be a no-op when unprivileged as it is impossible
for there to be any active networks
With the change to use a global set of firewall chains, however, we now
have code that is run unconditionally.
Ideally we would not register the network driver at all when
unprivileged, but the entanglement with the virt drivers currently makes
that impractical. As a temporary hack, we just make the firewall reload
into a no-op.

Subject: [PATCH] virSetUIDGIDWithCaps: Set bounding capabilities only with
CAP_SETPCAP
In one of my previous patches I've tried to postpone dropping
CAP_SETPCAP until the very end because it's needed for
capng_apply(). What I did not realize back then was that we might
not have the capability to begin with. Because of unknown reasons
capng_apply() pollutes logs only for CAPNG_SELECT_BOUNDS and not
for CAPNG_SELECT_CAPS.
Reproducer is really simple: run libvirtd as a regular user.
During its initialization, libvirtd will spawn some binaries
(dnsmasq, qemu-*, etc.) and while doing so it will try to drop
capabilities.
Anyway, let's call capng_apply(CAPNG_SELECT_BOUNDS) only if we
have the CAP_SETPCAP (which is tracked in need_setpcap variable).

Subject: [PATCH] qemu: Allow creating ppc64 guests with graphics and no USB
mouse
The existing behavior for ppc64 guests is to always add a USB
keyboard and mouse combo if graphics are present; unfortunately,
this means any attempt to use a USB tablet will cause both pointing
devices to show up in the guest, which in turn will result in poor
user experience.
We can't just stop adding the USB mouse or start adding a USB tablet
instead, because existing applications and users might rely on the
current behavior; however, we can avoid adding the USB mouse if a USB
tablet is already present, thus allowing users and applications to
create guests that contain a single pointing device.

Subject: [PATCH 1/2] wireshark: Switch to tvb_bytes_to_str()
When the dissector sees a byte sequence that is either an opaque
data (xdr_opaque) or a byte sequence (xdr_bytes) it formats the
bytes as a hex numbers using our own implementation. But
wireshark already provides a function for it: tvb_bytes_to_str().
NB, the reason why it returns a const string is so that callers
don't try to free it - the string is allocated using an allocator
which will decide when to free it.
The wireshark formatter was introduced in wireshark commit of
v1.99.2~479 and thus is present in the version we require at
least (2.6.0).

Subject: [PATCH 2/2] wireshark: Drop needless comment in dissect_xdr_bytes()
In the dissect_xdr_bytes() there's a comment that the string
allocated by xdr_bytes() can't be freed using xdr_free(). Well,
that is expected because xdr_bytes() used plain calloc() AND the
string is not an XDR struct but plain 'char *' type. Passing it
to xdr_free() must result in weird things happening.

Subject: [PATCH] cpu_x86: Do not cache microcode version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The microcode version checks are used to invalidate cached CPU data we
get from QEMU. To minimize /proc/cpuinfo parsing the microcode version
was only read when libvirtd started and cached for the daemon's
lifetime. However, the CPU microcode can change anytime (updating the
microcode package can automatically upload it to the CPU) and we need to
stop caching it to avoid using stale CPU model data.

Subject: [PATCH] qemu: Don't cache microcode version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
My earlier commit be46f61326 was incomplete. It removed caching of
microcode version in the CPU driver, which means the capabilities XML
will see the correct microcode version. But it is also cached in the
QEMU capabilities cache where it is used to detect whether we need to
reprobe QEMU. By missing the second place, the original commit
be46f61326 made the situation even worse since libvirt would report
correct microcode version while still using the old host CPU model
(visible in domain capabilities XML).

The admin protocol RPC messages are only intended for use by the user
running the daemon. As such they should not be allowed for any client
UID that does not match the server UID.

Subject: [PATCH] locking: restrict sockets to mode 0600
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The virtlockd daemon's only intended client is the libvirtd daemon. As
such it should never allow clients from other user accounts to connect.
The code already enforces this and drops clients from other UIDs, but
we can get earlier (and thus stronger) protection against DoS by setting
the socket permissions to 0600

Subject: [PATCH] qemu: Set up EMULATOR thread and cpuset.mems before
exec()-ing qemu
It's funny how this went unnoticed for such a long time. Long
story short, if a domain is configured with
VIR_DOMAIN_NUMATUNE_MEM_STRICT libvirt doesn't really honour
that. This is because of 7e72ac787848 after which libvirt allowed
qemu to allocate memory just anywhere and only after that it used
some magic involving cpuset.memory_migrate and cpuset.mems to
move the memory to desired NUMA nodes. This was done in order to
work around some KVM bug where KVM would fail if there wasn't a
DMA zone available on the NUMA node. Well, while the work around
might stopped libvirt tickling the KVM bug it also caused a bug
on libvirt side: if there is not enough memory on configured NUMA
node(s) then any attempt to start a domain must fail. Because of
the way we play with guest memory domains can start just happily.
The solution is to move the child we've just forked into emulator
cgroup, set up cpuset.mems and exec() qemu only after that.
This basically reverts 7e72ac787848b7434c9 which was a workaround
for kernel bug. This bug was apparently fixed because I've tested
this successfully with recent kernel.

Subject: [PATCH] qemu: blockjob: Fix saving of inactive XML after completed
legacy blockjob
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit c257352797 introduced a logic bug where we will never save the
inactive XML after a blockjob as the variable which was determining
whether to do so is cleared right before. Thus even if we correctly
modify the inactive state it will be rolled back when libvirtd is
restarted.
