Subject: [PATCH] virDomainDiskTranslateSourcePool: Check for disk type
correctly
When rewriting the virDomainDiskTranslateSourcePool() function in
v6.1.0-rc1~184 a typo was introduced. Previously, we allowed
startup policy only for those volumes which translated to
VIR_STORAGE_TYPE_FILE. But starting with the referenced commit,
the value we checked for was changed to VIR_STORAGE_VOL_FILE
which comes from a different enum and has a different value too.
This is wrong, because virStorageSourceGetActualType() returns a
value from the original enum.

Subject: [PATCH] network: make it safe to call networkSetupPrivateChains()
multiple times
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
networkSetupPrivateChains() is currently called only once per run of
libvirtd, so it can assume that errInitV4 and errInitV6 are empty/null
when it is called. In preparation for potentially calling this
function multiple times during one run, this patch moves the reset of
errInitV[46] to the top of the function, to assure no memory is
leaked.

Subject: [PATCH] network: force re-creation of iptables private chains on
firewalld restart
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When firewalld is stopped, it removes *all* iptables rules and chains,
including those added by libvirt. Since restarting firewalld means
stopping and then starting it, any time it is restarted, libvirt needs
to recreate all the private iptables chains it uses, along with all
the rules it adds.
We already have code in place to call networkReloadFirewallRules() any
time we're notified of a firewalld start, and
networkReloadFirewallRules() will call
networkPreReloadFirewallRules(), which calls
networkSetupPrivateChains(); unfortunately that last call is called
using virOnce(), meaning that it will only be called the first time
through networkPreReloadFirewallRules() after libvirtd starts - so of
course when firewalld is later restarted, the call to
networkSetupPrivateChains() is skipped.
The neat and tidy way to fix this would be if there was a standard way
to reset a pthread_once_t object so that the next time virOnce was
called, it would think the function hadn't been called, and call it
again. Unfortunately, there isn't any official way of doing that (we
*could* just fill it with 0 and hope for the best, but that doesn't
seem very safe.
So instead, this patch just adds a static variable called
chainInitDone, which is set to true after networkSetupPrivateChains()
is called for the first time, and then during calls to
networkPreReloadFirewallRules(), if chainInitDone is set, we call
networkSetupPrivateChains() directly instead of via virOnce().
It may seem unsafe to directly call a function that is meant to be
called only once, but I think in this case we're safe - there's
nothing in the function that is inherently "once only" - it doesn't
initialize anything that can't safely be re-initialized (as long as
two threads don't try to do it at the same time), and it only happens
when responding to a dbus message that firewalld has been started (and
I don't think it's possible for us to be processing two of those at
once), and even then only if the initial call to the function has
already been completed (so we're safe if we receive a firewalld
restart call at a time when we haven't yet called it, or even if
another thread is already in the process of executing it. The only
problematic bit I can think of is if another thread is in the process
of adding an iptable rule at the time we're executing this function,
but 1) none of those threads will be trying to add chains, and 2) if
there was a concurrency problem with other threads adding iptables
rules while firewalld was being restarted, it would still be a problem
even without this change.
This is yet another patch that fixes an occurrence of this error:
COMMAND_FAILED: '/usr/sbin/iptables -w10 -w --table filter --insert LIBVIRT_INP --in-interface virbr0 --protocol tcp --destination-port 67 --jump ACCEPT' failed: iptables: No chain/target/match by that name.
In particular, this resolves: https://bugzilla.redhat.com/1813830

Subject: [PATCH] rpc: ensure daemon is spawn even if dead socket exists
The auto-spawn code would originally attempt to spawn the
daemon for both ENOENT and ECONNREFUSED errors from connect().
The various refactorings eventually lost this so we only
spawn the daemon on ENOENT. The result is if the daemon exits
uncleanly, so that the socket is left in the filesystem, we
will never be able to auto-spawn the daemon again.

Subject: [PATCH] systemd: start libvirtd after firewalld/iptables services
When a system has enabled the iptables/ip6tables services rather than
firewalld, there is no explicit ordering of the start of those
services vs. libvirtd. This creates a problem when libvirtd.service is
started before ip[6]tables, as the latter, when it finally is started,
will remove all of the iptables rules that had previously been added
by libvirt, including the custom chains where libvirt's rules are
kept. This results in an error message similar to the following when a
user subsequently tries to start a new libvirt network:
"Error while activating network: Call to virNetworkCreate failed:
internal error: Failed to apply firewall rules
/usr/sbin/ip6tables -w --table filter --insert LIBVIRT_FWO \
--in-interface virbr2 --jump REJECT:
ip6tables: No chain/target/match by that name."
(Prior to logging this error, it also would have caused failure to
forward (or block) traffic in some cases, e.g. for guests on a NATed
network, since libvirt's rules to forward/block had all been deleted
and libvirt didn't know about it, so it couldn't fix the problem)
When this happens, the problem can be remedied by simply restarting
libvirtd.service (which has the side-effect of reloading all
libvirt-generated firewall rules)
Instead, we can just explicitly stating in the libvirtd.service file
that libvirtd.service should start after ip6tables.service and
ip6tables.service, eliminating the race condition that leads to the
error.
There is also nothing (that I can see) in the systemd .service files
to guarantee that firewalld.service will be started (if enabled) prior
to libvirtd.service. The same error scenario given above would occur
if libvirtd.service started before firewalld.service. Even before
that, though libvirtd would have detected that firewalld.service was
disabled, and then turn off all firewalld support. So, for example,
firewalld's libvirt zone wouldn't be used, and most likely traffic
from guests would therefore be blocked (all with no external
indication of the source of the problem other than a debug-level log
when libvirtd was started saying that firewalld wasn't in use); also
libvirtd wouldn't notice when firewalld reloaded its rules (which also
simultaneously deletes all of libvirt's rules).
I'm not aware of any reports that have been traced back to
libvirtd.service starting before firewalld.service, but have seen that
error reported multiple times, and also don't see an existing
dependency that would guarantee firewalld.service starts before
libvirtd.service, so it's possible it's been happening and we just
haven't gotten to the bottom of it.
This patch adds an After= line to the libvirtd.service file for each
of iptables.service, ip6tables.service, and firewalld.servicee, which
should guarantee that libvirtd.service isn't started until systemd has
started whichever of the others is enabled.
This race was diagnosed, and patch proposed, by Jason Montleon in
https://bugzilla.redhat.com/1723698 . At the time (April 2019) danpb
agreed with him that this change to libvirtd.service was a reasonable
thing to do, but I guess everyone thought someone else was going to
post a patch, so in the end nobody did.

Subject: [PATCH] libxl: fix crash when initializing driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 54a401af478 split out DriverConfigInit from DriverConfigNew, but
then called it a bit late from libxlStateInitialize. The cfg is used in
libxlDriverConfigLoadFile and when uninitialized results in a crash.
Calling DriverConfigInit immediately after DriverConfigNew fixes the
crash.

Subject: [PATCH] rpc: socket: Explicitly error if we exceed retry count
When we autolaunch libvirtd for session URIs, we spin in a retry
loop waiting for the daemon to start and the connect(2) to succeed.
However if we exceed the retry count, we don't explicitly raise an
error, which can yield a slew of different error messages elsewhere
in the code.
Explicitly raise the last connect(2) failure if we run out of retries.

Kernel/initrd files are essentially read-only shareable images and thus
should be handled in the same way. We already use the appropriate label
for kernel/initrd files when starting a domain, but when a domain gets
destroyed we would remove the labels which would make other running
domains using the same files very unhappy.

Many users, who admin their own machines, want to be able to access
system libvirtd via tools like virt-manager without having to enter
a root password. Just google 'virt-manager without password' and
you'll find many hits. I've read at least 5 blog posts over the years
describing slightly different ways of achieving this goal.
Let's finally add official support for this.
Install a polkit-1 rules file granting password-less auth for any user
in the new 'libvirt' group. Create the group on RPM install
