-Subject: [PATCH] interface: fix udev reference leak with invalid flags
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The udevInterfaceGetXMLDesc method takes a reference on the udev
-driver as its first action. If the virCheckFlags() condition
-fails, however, this reference is never released.

-Subject: [PATCH] rpc: avoid leak of GSource in use for interrupting main loop
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-We never release the reference on the GSource created for
-interrupting the main loop, nor do we remove it from the
-main context if our thread is woken up prior to the wakeup
-callback firing.
-
-This can result in a leak of GSource objects, along with an
-ever growing list of GSources attached to the main context,
-which will gradually slow down execution of the loop, as
-several operations are O(N) for the number of attached GSource
-objects.

-The root cause is a bad assumption in the virNetClientIOEventLoop
-method. This method is run by whichever thread currently owns the
-buck, and is responsible for handling I/O. Inside a for(;;) loop,
-this method creates a temporary GSource, adds it to the event loop
-and runs g_main_loop_run(). When I/O is ready, the GSource callback
-(virNetClientIOEventFD) will fire and call g_main_loop_quit(), and
-return G_SOURCE_REMOVE which results in the temporary GSource being
-destroyed. A g_autoptr() will then remove the last reference.
-
-What was overlooked, is that a second thread can come along and
-while it can't enter virNetClientIOEventLoop, it will register an
-idle source that uses virNetClientIOWakeup to interrupt the
-original thread's 'g_main_loop_run' call. When this happens the
-virNetClientIOEventFD callback never runs, and so the temporary
-GSource is not destroyed. The g_autoptr() will remove a reference,
-but by virtue of still being attached to the event context, there
-is an extra reference held causing GSource to be leaked. The
-next time 'g_main_loop_run' is called, the original GSource will
-trigger its callback, and access data that was allocated on the
-stack by the previous thread, and likely SEGV.
-
-To solve this, the thread calling 'g_main_loop_run' must call
-g_source_destroy, immediately upon return, to guarantee that
-the temporary GSource is removed.

+From: Laine Stump <laine@redhat.com>
+Date: Mon, 25 Nov 2024 22:24:45 -0500
+Subject: [PATCH 5/9] util: make it optional to clear existing tc
+ qdiscs/filters in virNetDevBandwidthSet()
+
+virNetDevBandwidthSet() always clears all existing qdiscs and their
+subordinate filters before adding all the new qdiscs/filters. This is
+normally exactly what we want, but there is one case (the network
+driver) where the Qdisc added by virNetDevBandwidthSet() may already
+be in use by the nftables backend (which will add a rule to fix the
+checksum of dhcp packets); in that case, we *don't* want
+virNetDevBandwidthSet() to clear out the qdisc that was already added
+for nftables, and none of the bandwidth filters have been added yet,
+so there already aren't any "old" filters that need to be removed
+either - it is safe to just skip virNetDevBandwidthClear() in this
+case.
+
+To allow the network driver to set bandwidth without first clearing
+it, this patch adds the flag VIR_NETDEV_BANDWIDTH_SET_CLEAR_ALL to the
+virNetDevBandwidthSetFlags enum, and recognizes it in
+virNetDevBandwidthSet() - if the flag is set, then
+virNetDevBandwidth() will call virNetDevBandwidthClear() just as it
+always has. But if the flag isn't set it *won't* call
+virNetDevBandwidthClear().
+
+As suggested above, VIR_NETDEV_BANDWIDTH_SET_CLEAR_ALL is set for all
+calls to virNetdevBandwidthSet() except for two places in the network
+driver.

+Subject: [PATCH 6/9] util: put the command that adds a tx filter qdisc into a
+ separate function
+
+virNetDevBandwidthSet() adds a queue discipline (qdisc) for each
+interface that it will need to add tc transmit filters to, and the
+filters are then attached to the qdisc.
+
+There are other circumstances where some other function will need to
+add tc transmit filters to an interface (in particular an upcoming
+patch to the network driver nftables backend that will use a tc tx
+filter to fix the checksum of dhcp packets), so that function will
+also need a qdisc for the tx filter. To assure both always use exactly
+the same qdisc, this patch puts the command that adds the tx filter
+qdisc into a separate helper function that can (and will) be called
+from either place

+Subject: [PATCH 7/9] util: don't re-add the qdisc used for tx filters if it
+ already exists
+
+There will soon be two separate users of tc on virtual networks, and
+both will use the "qdisc root handle 1: htb" to add tx filters. One or the
+other could get the first chance to add the qdisc, and then if at a
+later time the other decides to use it, we need to prevent the 2nd
+user from attempting to re-add the qdisc (because that just generates
+an error).
+
+We do this by running "tc qdisc show dev $bridge handle 1:" then
+checking if the output of that command contains both "qdisc" and " 1:
+".[*] If it does then the qdisc has already been added. If not then we
+need to add it now.
+
+[*]As of this writing, the output more exactly starts with "qdisc
+htb 1: root", but our comparison is made purposefully generous to
+increase the chances that it will continue to work properly if tc
+modifies the format of its output.

+
+If the layer of a virFirewallCmd is "tc", then the "tc" utility will
+be executed using the arguments that had been added to the
+virFirewallCmd
+
+tc layer doesn't support auto-rollback command creation (any rollback
+needs to be added manually with virFirewallAddRollbackCmd()), and also
+tc layer isn't supported by the iptables backend (it would have been
+straightforward to add, but the iptables backend doesn't need it, and
+I didn't want to take the chance of causing a regression in that
+code for no good reason).

+Subject: [PATCH 9/9] network: add tc filter rule to nftables backend to fix
+ checksum of DHCP responses
+
+Please see the commit log for commit v10.9.0-rc1-1-g42ab0148dd for the
+history and explanation of the problem that this patch is fixing.
+
+A shorter explanation is that when a guest is connected to a libvirt
+virtual network using a virtio-net adapter with in-kernel "vhost-net"
+packet processing enabled, it will fail to acquire an IP address from
+a DHCP seever running on the host.
+
+In commit v10.9.0-rc1-1-g42ab0148dd we tried fixing this by *zeroing
+out* the checksums of these packets with an nftables rule (nftables
+can't recompute the checksum, but it can set it to 0) . This
+*appeared* to work initially, but it turned out that zeroing the
+checksum ends up breaking dhcp packets on *non* virtio/vhost-net guest
+interfaces. That attempt was reverted in commit v10.9.0-rc2.
+
+Fortunately, there is an existing way to recompute the checksum of a
+packet as it leaves an interface - the "tc" (traffic control) utility
+that libvirt already uses for bandwidth management. This patch uses a
+tc filter rule to match dhcp response packets on the bridge and
+recompute their checksum.
+
+The filter rule must be attached to a tc qdisc, which may also have a
+filter attached for bandwidth management (in the <bandwidth> element
+of the network config). Not only must we add the qdisc only once
+(which was already handled by the patch two prior to this one), but
+also the filter rule for checksum fixing and the filter rule for
+bandwidth management must be different priorities so they don't clash;
+this is solved by adding the checksum-fix filter with "priority 2",
+while the bandwidth management filter remains "priority 1" (both will
+always be evaluated anyway, it's just a matter of which is evaluated
+first).
+
+So far this method has worked with every different guest we could
+throw at it, including several that failed with the previous method.

+ * nftablesAddUdpChecksumFixWithTC:
+ *
+ * Add a tc filter rule to @ifname (the bridge device of this network)
+ * that will recompute the checksum of udp packets output from @iface with
+ * destination port @port.
+ *
+ * Normally the checksum should be filled by some part of the basic
+ * network stack, but there are cases (e.g. DHCP response packets sent
+ * from virtualization host to a QEMU guest when the guest NIC uses
+ * vhost-net packet processing) when the host (sender) thinks that
+ * packet checksums will be computed elsewhere (and so leaves a
+ * partially computed checksum in the packet header) while the guest
+ * (receiver) thinks that the checksum has already been fully
+ * computed; in the meantime none of the code in between has actually
+ * finished computing the checksum.
+ *
+ * An example of this is DHCP response packets from host to guest. If
+ * the checksum of each of these packets isn't properly computed, then
+ * many guests (e.g. FreeBSD) will drop them with reason BAD CHECKSUM;
+ * this tc filter rule will fix the ip and udp checksums, and the
+ * FreeBSD dhcp client will happily accept the packet.
+ *
+ * (NB: if you're wondering how the tc qdisc and filter are removed
+ * when the network is destroyed, the answer is that the kernel
+ * automatically (and properly) removes them for us, so we don't need
+ * to worry about keeping track/deleting as we do with nftables rules)

+Subject: [PATCH] network: permit <forward mode='open'/> when a network has no
+ IP address
+Content-type: text/plain
+
+The whole point of <forward mode='open'/> is to supress libvirt from
+adding any firewall rules for a network, and someone might want to
+create a network with no IP address (i.e. they don't want the guests
+to have connectivity to the host via this interface) and no firewall
+rules (they don't want any, or they want to add their own). So there's
+no reason to fail when a network has <forward mode='open'/> and also
+has no IP address.

+Subject: [PATCH] qemu: snapshot: delete disk image only if parent snapshot is
+ external
+Content-type: text/plain
+
+When we are deleting external snapshot that is not active we only need
+to delete overlay disk image of the parent snapshot. This works
+correctly even if parent snapshot is external and active as it will have
+another overlay created when user reverted to that snapshot.
+
+In case the parent snapshot is internal there are no overlay disk images
+created as everything is stored internally within the disk image. In
+this case we would delete the actual disk image storing internal
+snapshots and most likely the original disk image as well resulting in
+data loss once the VM is shutoff.
