+
+Use convenience macro which does almost the same thing we were doing,

+Subject: [PATCH] virarptable: Fix check for message length
+Content-type: text/plain
+
+The previous check was all wrong since it calculated the how long would
+the netlink message be if the netlink header was the payload and then
+subtracted that from the whole message length, a variable that was not
+used later in the code.  This check can fail if there are no additional
+payloads, struct rtattr in particular, which we are parsing later,
+however the RTA_OK macro would've caught that anyway.

+Subject: [PATCH] virarptable: End parsing earlier in case of NLMSG_DONE
+Content-type: text/plain
+
+Check for the last multipart message right as the first thing.  The
+presumption probably was that the last message might still contain a
+payload we want to parse.  However that cannot be true since that would
+have to be a type RTM_NEWNEIGH.  This was not caught because older
+kernels were note sending NLMSG_DONE and probably relied on the fact
+that the parsing just stops after all the messages are walked through,
+which the NLMSG_OK macro successfully did.

+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.

+
+virNetDevBandwidthSet() adds a queue discipline (qdisc) for each

+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

+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.

-    daemon: Export SDL audio environment variables
-    
-    /etc/sysconfig/libvirtd has a few environment variables for configuring
-    libvirt SDL audio. The libvirtd process doesn't see these, however, because
-    they are never exported. Let's export the variables after sourcing the
-    sysconfig script.
-    
-    There is another problem here that the commented out values in the
-    sysconfig script are not neccessarily the actual defaults, we are qemus
-    mercy here. Not sure how to solve that.

-    qemu: Allow using regular audio backends with VNC
-    
-    Currently all host audio backends are disabled if a VM is using VNC, in
-    favor of the QEMU VNC audio extension. Unfortunately no released VNC
-    client supports this extension, so users have no way of getting audio
-    to work if using VNC.
-    
-    Add a new config option in qemu.conf which allows changing libvirt's
-    behavior, but keep the default intact.
-    
-    v2: Fix doc typos, change name to vnc_allow_host_audio

-    Fix CDROM media change for QEMU when using -device syntax
-    
-    Disk devices in QEMU have two parts, the guest device and the host
-    backend driver. Historically these two parts have had the same
-    "unique" name. With the switch to using -device though, they now
-    have separate names. Thus when changing CDROM media, for guests
-    using -device syntax, we need to prepend the QEMU_DRIVE_HOST_PREFIX
-    constant
-    
-    * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add helper function
-      qemuDeviceDriveHostAlias() for building a host backend alias
-    * src/qemu/qemu_driver.c: Use qemuDeviceDriveHostAlias() to determine
-      the host backend alias for performing eject/change commands in the
-      monitor

-    Trivial virsh.pod additions --all for "list" command and similar
-    
-    This is just a trivial patch to virsh.pod (from git master). It adds the
-    following pieces to the virsh man page:
-    
-      + Shows the --inactive and --all optional parameters for the list
-        command.
-    
-        Closes Bugzilla #575512, reported by Renich Bon Ciric
-        https://bugzilla.redhat.com/show_bug.cgi?id=575512

-      + Corrects the existing description of the list command, to now say
-        that only running domains are listed if no domains are specified.
-    
-        The man page up until this point has said all domains are listed if
-        no domains are specified, which is incorrect.
-    
-      + Adds the "shut off" state to the list of states for the list
-        command.
-    
-      + Adds a missing =back around line 755, that pod2man was complaining
-        was missing.

-    network: bridge: Don't start network if it collides with host routing
-    
-    Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=235961
-    
-    If using the default virtual network, an easy way to lose guest network
-    connectivity is to install libvirt inside the VM. The autostarted
-    default network inside the guest collides with host virtual network
-    routing. This is a long standing issue that has caused users quite a
-    bit of pain and confusion.
-    
-    On network startup, parse /proc/net/route and compare the requested
-    IP+netmask against host routing destinations: if any matches are found,
-    refuse to start the network.
-    
-    v2: Drop sscanf, fix a comment typo, comment that function could use
-        libnl instead of /proc
-    
-    v3: Consider route netmask. Compare binary data rather than convert to
-        string.
-    
-    v4: Return to using sscanf, drop inet functions in favor of virSocket,
-        parsing safety checks. Don't make parse failures fatal, in case
-        expected format changes.
-    
-    v5: Try and continue if we receive unexpected. Delimit parsed lines to
-        prevent scanning past newline

-    Don't crash without a security driver
-    
-    "virsh dominfo <vm>" crashes if there's no primary security driver set
-    since we only intialize the secmodel.model and secmodel.doi if we have
-    one. Attached patch checks for securityPrimaryDriver instead of
-    securityDriver since the later is always set in qemudSecurityInit().
-    
-    Closes: http://bugs.debian.org/574359

-    qemu: Report cmdline output if VM dies early
-    
-    qemuReadLogOutput early VM death detection is racy and won't always work.
-    Startup then errors when connecting to the VM monitor. This won't report
-    the emulator cmdline output which is typically the most useful diagnostic.
-    
-    Check if the VM has died at the very end of the monitor connection step,
-    and if so, report the cmdline output.
-

-commit 07f6c3a95f1caca368c8723b5b0a25ae2faa1ffe
-Author: David Allan <dallan@redhat.com>
-Date:   Thu May 27 10:44:02 2010 -0400
-
-    v2 of Cole's wlan support
-    
-    * Incorporated Jim's feedback (v1 & v2)
-    
-    * Moved case of DEVTYPE == "wlan" up as it's definitive that we have a network interface.
-    
-    * Made comment more detailed about the wired case to explain better
-      how it differentiates between wired network interfaces and USB
-      devices.
