+Check for the last multipart message right as the first thing.  The

+have to be a type RTM_NEWNEIGH.  This was not caught because older

-Subject: [PATCH] qemu: ensure TLS clients always verify the server certificate
-
-The default_tls_x509_verify (and related) parameters in qemu.conf
-control whether the QEMU TLS servers request & verify certificates
-from clients. This works as a simple access control system for
-servers by requiring the CA to issue certs to permitted clients.
-This use of client certificates is disabled by default, since it
-requires extra work to issue client certificates.
-
-Unfortunately the code was using this configuration parameter when
-setting up both TLS clients and servers in QEMU. The result was that
-TLS clients for character devices and disk devices had verification
-turned off, meaning they would ignore errors while validating the
-server certificate.
-
-This allows for trivial MITM attacks between client and server,
-as any certificate returned by the attacker will be accepted by
-the client.
-
-This is assigned CVE-2017-1000256  / LSN-2017-0002

+From 807e2670f2704c41f0a1dca81a5d2f2f9336137c Mon Sep 17 00:00:00 2001
+From: Laine Stump <laine@redhat.com>
+Date: Mon, 25 Nov 2024 22:24:44 -0500
+Subject: [PATCH 4/9] util: use a single flags arg for virNetDevBandwidthSet(),
+ not multiple bools
+
+Having two bools in the arg list is on the borderline of being
+confusing to anyone trying to read the code, but we're about to add a
+3rd. This patch replaces the two bools with a single flags argument
+which will instead have one or more bits from virNetDevBandwidthFlags
+set.

+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.

+Subject: [PATCH 8/9] util: add new "tc" layer for virFirewallCmd objects
+
+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.

-The PROBE macro used in qemuMonitorIOProcess and the VIR_DEBUG message

-The messages logged from the PROBE macro are rather useless since they

-Subject: [PATCH] qemuDomainAttachDeviceMknodHelper: Remove symlink before
- creating it
-
-https://bugzilla.redhat.com/show_bug.cgi?id=1528502
-
-So imagine you have /dev/blah symlink which points to /dev/sda.
-You attach /dev/blah as disk to your domain. Libvirt correctly
-creates the /dev/blah -> /dev/sda symlink in the qemu namespace.
-However, then you detach the disk, change the symlink so that it
-points to /dev/sdb and tries to attach the disk again. This time,
-however, the attach fails (well, qemu attaches wrong disk)
-because the code assumes that symlinks don't change. Well they
-do.
-
-This is inspired by test fix written by Eduardo Habkost.

-Subject: [PATCH] nwfilter: increase pcap buffer size to be compatible with
- TPACKET_V3
-
-When an nwfilter rule sets the parameter CTRL_IP_LEARNING to "dhcp",
-this turns on the "dhcpsnoop" thread, which uses libpcap to monitor
-traffic on the domain's tap device and extract the IP address from the
-DHCP response.
-
-If libpcap on the host is built with HAVE_TPACKET3 defined (to enable
-support for TPACKET_V3), the dhcpsnoop code's initialization of the
-libpcap socket would fail with the following error:
-
-  virNWFilterSnoopDHCPOpen:1134 : internal error: pcap_setfilter: can't remove kernel filter: Bad file descriptor
-
-It turns out that this was because TPACKET_V3 requires a larger buffer
-size than libvirt was setting (we were setting it to 128k). Changing
-the buffer size to 256k eliminates the error, and the dhcpsnoop thread
-once again works properly.
-
-A fuller explanation of why TPACKET_V3 requires such a large buffer,
-for future git spelunkers:
-
-libpcap calls setsockopt(... SOL_PACKET, PACKET_RX_RING...) to setup a
-ring buffer for receiving packets; two of the attributes sent to this
-API are called tp_frame_size, and tp_frame_nr. If libpcap was built
-with HAVE_TPACKET3 defined, tp_trame_size is set to MAXIMUM_SNAPLEN
-(defined in libpcap sources as 262144) and tp_frame_nr is set to:
-
- [the buffer size we set, i.e. PCAP_BUFFERSIZE i.e. 262144] / tp_frame_size.
-
-So if PCAP_BUFFERSIZE < MAXIMUM_SNAPLEN, then tp_frame_nr (the number
-of frames in the ring buffer) is 0, which is nonsensical. This same
-value is later used as a multiplier to determine the size for a call
-to malloc() (which would also fail).
-
-(NB: if HAVE_TPACKET3 is *not* defined, then tp_frame_size is set to
-the snaplen set by the user (in our case 576) plus a small amount to
-account for ethernet headers, so 256k is far more than adequate)
-
-Since the TPACKET_V3 code in libpcap actually reads multiple packets
-into each frame, it's not a problem to have only a single frame
-(especially when we are monitoring such infrequent traffic), so it's
-okay to set this relatively small buffer size (in comparison to the
-default, which is 2MB), which is important since every guest using
-dhcp snooping in a nwfilter rule will hold 2 of these buffers for the
-entire life of the guest.
-
-Thanks to Christian Ehrhardt for discovering that buffer size was the
-problem (this was not at all obvious from the error that was logged!)

-Subject: [PATCH 16/19] qemu: capabilities: force update if the microcode
- version does not match
-
-A microcode update can cause the CPUID bits to change; an example
-from the past was the update that disabled TSX on several Haswell
-and Broadwell machines.
-
-Therefore, place microcode version in the virQEMUCaps struct and
-XML, and rebuild the cache if the versions do not match.

-CVE-2017-5715

- (CVE-2018-3639)

-Content-Transfer-Encoding: 8bit
-
-Some AMD processors only support a non-architectural means of
-enabling Speculative Store Bypass Disable. To allow simplified
-handling in virtual environments, hypervisors will expose an
-architectural definition through CPUID bit 0x80000008_EBX[25].
-This needs to be exposed to guest OS running on AMD x86 hosts to
-allow them to protect against CVE-2018-3639.
-
-Note that since this CPUID bit won't be present in the host CPUID
-results on physical hosts, it will not be enabled automatically
-in guests configured with "host-model" CPU unless using QEMU
-version >= 2.9.0. Thus for older versions of QEMU, this feature
-must be manually enabled using policy=force. Guests using the
-"host-passthrough" CPU mode do not need special handling.
