Subject: [PATCH] virarptable: Properly calculate rtattr length
Content-type: text/plain
Use convenience macro which does almost the same thing we were doing,
but also pads out the payload length to a multiple of NLMSG_ALIGNTO (4)
bytes.

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.

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.

+ * 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

+ * partially computed checksum in the packet header) while the guest
+ * (receiver) thinks that the checksum has already been fully

+ * 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

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.

Subject: [PATCH] nss: Skip empty files and avoid use of uninitialized value
Content-type: text/plain
JSON parser isn't called when reading empty files so `jerr` will be used
uninitialized in the original code. Empty files appear when a network
has no dhcp clients.
This patch checks for such files and skip them.

Subject: [PATCH] qemu: Be more forgiving when acquiring QUERY job when
formatting domain XML
Content-type: text/plain
In my previous commit of v11.0.0-rc1~115 I've made QEMU driver
implementation for virDomainGetXMLDesc() (qemuDomainGetXMLDesc())
acquire QERY job. See its commit message for more info. But this
unfortunately broke apps witch fetch domain XML for incoming
migration (like virt-manager). The reason is that for incoming
migration the VIR_ASYNC_JOB_MIGRATION_IN async job is set, but
the mask of allowed synchronous jobs is empty (because QEMU can't
talk on monitor really). This makes virDomainObjBeginJob() fail
which in turn makes qemuDomainGetXMLDesc() fail too.
It makes sense for qemuDomainGetXMLDesc() to acquire the job
(e.g. so that it's coherent with another thread that might be in
the middle of a MODIFY job). But failure to dump XML may be
treated as broken daemon (e.g. virt-manager does so).
Therefore, still try to acquire the QUERY job (if job mask
permits it) but, do not treat failure as an error.
