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.

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.

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.
