+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: 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] Don't pass virConnectPtr in nwfilter 'struct
- domUpdateCBStruct'
-
-The nwfilter driver only needs a reference to its private
-state object, not a full virConnectPtr. Update the domUpdateCBStruct
-struct to have a 'void *opaque' field instead of a virConnectPtr.

+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] Remove use of virConnectPtr from all remaining nwfilter code
-
-The virConnectPtr is passed around loads of nwfilter code in
-order to provide it as a parameter to the callback registered
-by the virt drivers. None of the virt drivers use this param
-though, so it serves no purpose.
-
-Avoiding the need to pass a virConnectPtr means that the
-nwfilterStateReload method no longer needs to open a bogus
-QEMU driver connection. This addresses a race condition that
-can lead to a crash on startup.
-
-The nwfilter driver starts before the QEMU driver and registers
-some callbacks with DBus to detect firewalld reload. If the
-firewalld reload happens while the QEMU driver is still starting
-up though, the nwfilterStateReload method will open a connection
-to the partially initialized QEMU driver and cause a crash.

+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.
