From 5f6723e71e3765d1d43bfa9ba1c66e0e05e11a48 Mon Sep 17 00:00:00 2001
Message-Id: <5f6723e71e3765d1d43bfa9ba1c66e0e05e11a48@dist-git>
From: Michal Privoznik <mprivozn@redhat.com>

Subject: [PATCH] Allow NUMA nodes without vCPUs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
QEMU allows creating NUMA nodes that have memory only.
These are somehow important for HMAT.
With check done in qemuValidateDomainDef() for QEMU 2.7 or newer
(checked via QEMU_CAPS_NUMA), we can be sure that the vCPUs are
fully assigned to NUMA nodes in domain XML.

Reviewed-by: Daniel Henrique Barboza <danielhb413@gmail.com>
(cherry picked from commit a26f61ee0cffa421b87ef568002b684dd8025432)
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1749518
Conflicts:
- src/qemu/qemu_validate.c: This file doesn't exist in downstream
yet, so I've moved the change that original patch would do to
qemu_domain.c where the validator lives.

So far, the <cell/> element can have two types of children
elements: <distances/> and <cache/> (which can be repeated more
times). However, there is no reason to require specific order in
input XML. Allow elements to be interleaved.

Subject: [PATCH] check for NULL before calling g_regex_unref
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
g_regex_unref reports an error if called with a NULL argument.
We have two cases in the code where we (possibly) call it on a NULL
argument. The interesting one is in virDomainQemuMonitorEventCleanup.
Based on VIR_CONNECT_DOMAIN_QEMU_MONITOR_EVENT_REGISTER_REGEX, we unref
data->regex, which has two problems:
* On the client side, flags is -1 so the comparison is true even if no
regex was used, reproducible by:
$ virsh qemu-monitor-event --timeout 1
which results in an ugly error:
(process:1289846): GLib-CRITICAL **: 14:58:42.631: g_regex_unref: assertion 'regex != NULL' failed
* On the server side, we only create the regex if both the flag and the
string are present, so it's possible to trigger this message by:
$ virsh qemu-monitor-event --regex --timeout 1
Use a non-NULL comparison instead of the flag to decide whether we need
to unref the regex. And add a non-NULL check to the unref in the
VirtualBox test too.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There is nothing domain specific about the function, thus it
should not have virDomain prefix. Also, the fact that it is a
static function makes it impossible to use from other files.
Move the function to virxml.c and drop the 'Domain' infix.

+ <span class='since'>Since 6.6.0</span> the <code>cell</code> element can
+ have a <code>cache</code> child element which describes memory side cache
+ for memory proximity domains. The <code>cache</code> element has a
+ <code>level</code> attribute describing the cache level and thus the
+ element can be repeated multiple times to describe different levels of
+ the cache.
+ </p>
+
+ <p>
+ The <code>cache</code> element then has following mandatory attributes:
+ </p>
+
+ <dl>
+ <dt><code>level</code></dt>
+ <dd>
+ Level of the cache this description refers to.
+ </dd>
+
+ <dt><code>associativity</code></dt>
+ <dd>
+ Describes cache associativity (accepted values are <code>none</code>,
+ <code>direct</code> and <code>full</code>).
+ </dd>
+
+ <dt><code>policy</code></dt>
+ <dd>
+ Describes cache write associativity (accepted values are
+ <code>none</code>, <code>writeback</code> and
+ <code>writethrough</code>).
+ </dd>
+ </dl>
+
+ <p>
+ The <code>cache</code> element has two mandatory child elements then:
+ <code>size</code> and <code>line</code> which describe cache size and
+ cache line size. Both elements accept two attributes: <code>value</code>
+ and <code>unit</code> which set the value of corresponding cache
+ attribute.
+ </p>
+
+ <p>
+ The NUMA description has an optional <code>interconnects</code> element that
+ describes the normalized memory read/write latency, read/write bandwidth
+ between Initiator Proximity Domains (Processor or I/O) and Target
+ Proximity Domains (Memory).
+ </p>
+
+ <p>
+ The <code>interconnects</code> element can have zero or more
+ <code>latency</code> child elements to describe latency between two
+ memory nodes and zero or more <code>bandwidth</code> child elements to
+ describe bandwidth between two memory nodes. Both these have the
+ following mandatory attributes:
+ </p>
+
+ <dl>
+ <dt><code>initiator</code></dt>
+ <dd>Refers to the source NUMA node</dd>
+
+ <dt><code>target</code></dt>
+ <dd>Refers to the target NUMA node</dd>
+
+ <dt><code>type</code></dt>
+ <dd>The type of the access. Accepted values: <code>access</code>,
+ <code>read</code>, <code>write</code></dd>
+
+ <dt><code>value</code></dt>
+ <dd>The actual value. For latency this is delay in nanoseconds, for
+ bandwidth this value is in kibibytes per second. Use additional
+ <code>unit</code> attribute to change the units.</dd>
+ </dl>
+
+ <p>
+ To describe latency from one NUMA node to a cache of another NUMA node
+ the <code>latency</code> element has optional <code>cache</code>
+ attribute which in combination with <code>target</code> attribute creates
+ full reference to distant NUMA node's cache level. For instance,
+ <code>target='0' cache='1'</code> refers to the first level cache of NUMA
+ node 0.

Subject: [PATCH] conf: properly clear out autogenerated macvtap names when
formatting/parsing
Back when macvtap support was added in commit 315baab9443 in Feb. 2010
(libvirt-0.7.7), it was setup to autogenerate a name for the device if
one wasn't supplied, in the pattern "macvtap%d" (or "macvlan%d"),
similar to the way an unspecified standard tap device name will lead
to an autogenerated "vnet%d".
As a matter of fact, in commit ca1b7cc8e45 added in May 2010, the code
was changed to *always* ignore a supplied device name for macvtap
interfaces by deleting *any* name immediately during the <interface>
parsing (this was intended to prevent one domain which had failed to
completely start from deleting the macvtap device of another domain
which had subsequently been provided the same device name (this will
seem mildly ironic later). This was later fixed to only clear the
device name when inactive XML was being parsed. HOWEVER - this was
only done if the xml was <interface type='direct'> - autogenerated
names were not cleared for <interface type='network'> (which could
also result in a macvtap device).
Although the names of "vnetX" tap devices had always been
automatically cleared when parsing <interface> (see commit d1304583d
from July 2008 (!)), at the time macvtap support was added, both vnetX
and macvtapX device names were always included when formatting the
XML.
Then in commit a8be259d0cc (July 2011, libvirt-0.9.4), <interface>
formatting was changed to also clear out "vnetX" device names during
XML formatting as well. However the same treatment wasn't given to
"macvtapX".
Now in 2020, there has been a report that a failed migration leads to
the macvtap device of some other unrelated guest on the destination
host losing its network connectivity. It was determined that this was
due to the domain XML in the migration containing a macvtap device
name, e.g. "macvtap0", that was already in use by the other guest on
the destination. Normally this wouldn't be a problem, because libvirt
would see that the device was already in use, and then find a
different unused name. But in this case, other external problems were
causing the migration to fail prior to selecting a macvtap device and
successfully opening it, and during error recovery, qemuProcessStop()
was called, which went through all def->nets objects and (if they were
macvtap) deleted the device specified in net->ifname; since libvirt
hadn't gotten to the point of replacing the incoming "macvtap0" with
the name of a device it actually created for this guest, that meant
that "macvtap0" was deleted, *even though it was currently in use by a
different guest*!
Whew!
So, it turns out that when formatting "migratable" XML, "vnetX"
devices are omitted, just as when formatting "inactive" XML. By making
the code in both interface parsing and formatting consistent for
"vnetX", "macvtapX", and "macvlanX", we can thus make sure that the
autogenerated (and unneeded / completely *not* wanted) macvtap device
name will not be sent with the migration XML. This way when a
migration fails, net->ifname will be NULL, and libvirt won't have any
device to try and (erroneously) delete.

Subject: [PATCH] cpu_map: Define and enable Snowridge model
Due to missing pdpe1gb support in the host CPU data, the CPU is still
incorrectly detected as Westmere-IBRS for host capabilities because we
don't have the option to disable features included in the base model
there.

Subject: [PATCH] cpu_map: Remove monitor feature from EPYC-Rome
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The feature is filtered by KVM and never automatically enabled. So even
though QEMU definition of EPYC-Rome contains this feature, the guest
won't see it. Also domain capabilities will show it as disabled for KVM
domains. Thus the feature should not really be included in our
definition of EPYC-Rome.

Subject: [PATCH] domain_validate: use defines for cpu period and quota limits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commints <bc760f4d7c4f964fadcb2a73e126b0053e7a9b06> and
<98a09ca48ed4fc011abf2aa290e02ce1b8f1bb5f> fixed the code to use
defines instead of magic numbers but missed this place.
Following commit <ed1ba69f5a8132f8c1e73d2a1f142d70de0b564a> changed
the cpu quota limit to reflect what kernel actually allows so using
the defines fixes XML validations as well.

MIME-Version: 1.0

There is only one caller of virDomainNumaSetNodeCpumask() which
checks for the return value but because the function will return
NULL iff the @cpumask was NULL in the first place. But in that
place @cpumask can't be NULL because it was just allocated by
virBitmapParse().

Subject: [PATCH] numa_conf: Properly check for caches in
virDomainNumaDefValidate()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When adding support for HMAT, in f0611fe8830 I've introduced a
check which aims to validate /domain/cpu/numa/interconnects. As a
part of that, there is a loop which checks whether all <latency/>
with @cache attribute refer to an existing cache level. For
instance:
<cpu mode='host-model' check='partial'>
<numa>
<cell id='0' cpus='0-5' memory='512000' unit='KiB' discard='yes'>
<cache level='1' associativity='direct' policy='writeback'>
<size value='8' unit='KiB'/>
<line value='5' unit='B'/>
</cache>
</cell>
<interconnects>
<latency initiator='0' target='0' cache='1' type='access' value='5'/>
<bandwidth initiator='0' target='0' type='access' value='204800' unit='KiB'/>
</interconnects>
</numa>
</cpu>
This XML defines that accessing L1 cache of node #0 from node #0
has latency of 5ns.
However, the loop was not written properly. Well, the check in
it, as it was always checking for the first cache in the target
node and not the rest. Therefore, the following example errors
out:
<cpu mode='host-model' check='partial'>
<numa>
<cell id='0' cpus='0-5' memory='512000' unit='KiB' discard='yes'>
<cache level='3' associativity='direct' policy='writeback'>
<size value='10' unit='KiB'/>
<line value='8' unit='B'/>
</cache>
<cache level='1' associativity='direct' policy='writeback'>
<size value='8' unit='KiB'/>
<line value='5' unit='B'/>
</cache>
</cell>
<interconnects>
<latency initiator='0' target='0' cache='1' type='access' value='5'/>
<bandwidth initiator='0' target='0' type='access' value='204800' unit='KiB'/>
</interconnects>
</numa>
</cpu>
This errors out even though it is a valid configuration. The L1
cache under node #0 is still present.

Subject: [PATCH] qemu: Fix domfsinfo for non-PCI device information from guest
agent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
qemuAgentFSInfoToPublic() currently only sets the devAlias for PCI devices.
However, the QEMU guest agent could also provide the device name in the
"dev" field of the response for other devices instead (well, at least after
fixing another problem in the current QEMU guest agent...). So if creating
the devAlias from the PCI information failed, let's fall back to the name
provided by the guest agent. This helps to fix the empty "Target" fields
that occur when running "virsh domfsinfo" on s390x where CCW devices are
used for the guest instead of PCI devices.
Also add a proper debug message here in case we completely failed to set the
device alias, since this problem here was very hard to debug: The only two
error messages that I've seen were "Unable to get filesystem information"
and "Unable to encode message payload" - which only indicates that something
went wrong in the RPC call. No debug message indicated the real problem, so
I had to learn the hard way why the RPC call failed (it apparently does not
like devAlias left to be NULL) and where the real problem comes from.

Subject: [PATCH] qemu: format 'ramfb' attribute for mediated devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It's possible to use ramfb as the boot display of an assigned vgpu
device. This was introduced in 4b95738c, but unfortunately the attribute
was not formatted into the xml output for such a device. This patch
fixes that oversight and adds a xml2xml test to verify proper behavior.
https://bugzilla.redhat.com/show_bug.cgi?id=1847791
(the expected test results were massaged slightly due to the fact that
commit 3b8feb4793cef66f5dbfb9bdabe4d40834f1e90e is not present in this
build).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A few commits ago, in aeecbc87b73, I've implemented command line
generation for ACPI HMAT. For this, we need to know if at least
one guest NUMA node has vCPUs. This is tracked in
@masterInitiator variable, which is initialized to -1, then we
iterate through guest NUMA nodes and break the loop if we find a
node with a vCPU. After the loop, if masterInitiator is still
negative then no NUMA node has a vCPU and we error out. But this
exact check was missing comparison for negativeness.

Subject: [PATCH] qemuFirmwareFillDomain: Fill NVRAM template on migration too
In 8e1804f9f66 I've tried to fix the following use case: domain
is started with path to UEFI only and relies on libvirt to figure
out corresponding NVRAM template to create a per-domain copy
from. The fix consisted of having a check tailored exactly for
this use case and if it's hit then using FW autoselection to
figure it out. Unfortunately, the NVRAM template is not saved in
the inactive XML (well, the domain might be transient anyway).
Then, as a part of that check we see whether the per-domain copy
doesn't exist already and if it does then no template is looked
up hence no template will appear in the live XML.
This works, until the domain is migrated. At the destination, the
per-domain copy will not exist so we need to know the template to
create the per-domain copy from. But we don't even get to the
check because we are not starting a fresh new domain and thus the
qemuFirmwareFillDomain() function quits early.
The solution is to switch order of these two checks. That is
evaluate the check for the old style before checking flags.

Subject: [PATCH] tests: fix iptables test case commandline options in
virfirewalltest.c
This test was created with all the commandlines erroneously having
"--source-host", which is not a valid iptables option. The correct
name for the option is "--source". However, since the test is just
checking that the generated commandline matches what we told it to
generate (and never actually runs iptables, as that would be a "Really
Bad Idea"(tm)), the test has always succeeded. I only found it because
I made a change to the code that caused the test to incorrectly try to
run iptables during the test, and the error message I received was
"odd" (it complained about the bad option, rather than complaining
that I had insufficient privilege to run the command).

Subject: [PATCH] util: Add phys_port_name support on virPCIGetNetName
virPCIGetNetName is used to get the name of the netdev associated with
a particular PCI device. This is used when we have a VF name, but need
the PF name in order to send a netlink command (e.g. in order to
get/set the MAC address of the VF).
In simple cases there is a single netdev associated with any PCI
device, so it is easy to figure out the PF netdev for a VF - just look
for the PCI device that has the VF listed in its "virtfns" directory;
the only name in the "net" subdirectory of that PCI device's sysfs
directory is the PF netdev that is upstream of the VF in question.
In some cases there can be more than one netdev in a PCI device's net
directory though. In the past, the only case of this was for SR-IOV
NICs that could have multiple PF's per PCI device. In this case, all
PF netdevs associated with a PCI address would be listed in the "net"
subdirectory of the PCI device's directory in sysfs. At the same time,
all VF netdevs and all PF netdevs have a phys_port_id in their sysfs,
so the way to learn the correct PF netdev for a particular VF netdev
is to search through the list of devices in the net subdirectory of
the PF's PCI device, looking for the one netdev with a "phys_port_id"
matching that of the VF netdev.
But starting in kernel 5.8, the NVIDIA Mellanox driver began linking
the VFs' representor netdevs to the PF PCI address [1], and so the VF
representor netdevs would also show up in the net
subdirectory. However, all of the devices that do so also only have a
single PF netdev for any given PCI address.
This means that the net directory of the PCI device can still hold
multiple net devices, but only one of them will be the PF netdev (the
others are VF representors):
$ ls '/sys/bus/pci/devices/0000:82:00.0/net'
ens1f0 eth0 eth1
In this case the way to find the PF device is to look at the
"phys_port_name" attribute of each netdev in sysfs. All PF devices
have a phys_port_name matching a particular regex
(p[0-9]+$)|(p[0-9]+s[0-9]+$)
Since there can only be one PF in the entire list of devices, once we
match that regex, we've found the PF netdev.

(cherry picked from commit 5b1c525b1f3608156884aed0dc5e925306c1e260)
Conflicts: src/util/virpci.c - upstream all DIR* were converted to use
g_autoptr, which permitted virPCIGetNetName() to be
simplified. Unfortunately, backporting this refactor would require
backporting an ever-ballooning set of patches, making the
possibility of causing a regression a very real danger. Instead,
one small refactor of virPCIGetName() that didn't affect any other
functions was backported, and this patch (adding phys_port_name
support) resolved the remaining conflicts by mimicking the current
upstream version of the function, but with all "return 0" replaced
by "ret = 0; goto cleanup;" and all "return -1" replaced by "goto
cleanup;" (the code at cleanup: just closes the DIR* and returns
the current value of ret). This will assure identical behavior to
upstream.

Subject: [PATCH] util: always check for ebtables/iptables binaries, even when
using firewalld
Even though *we* don't call ebtables/iptables/ip6tables (yet) when the
firewalld backend is selected, firewalld does, so these binaries need
to be there; let's check for them. (Also, the patch after this one is
going to start execing those binaries directly rather than via
firewalld).

Subject: [PATCH] util: assign tap device names using a monotonically
increasing integer
When creating a standard tap device, if provided with an ifname that
contains "%d", rather than taking that literally as the name to use
for the new device, the kernel will instead use that string as a
template, and search for the lowest number that could be put in place
of %d and produce an otherwise unused and unique name for the new
device. For example, if there is no tap device name given in the XML,
libvirt will always send "vnet%d" as the device name, and the kernel
will create new devices named "vnet0", "vnet1", etc. If one of those
devices is deleted, creating a "hole" in the name list, the kernel
will always attempt to reuse the name in the hole first before using a
name with a higher number (i.e. it finds the lowest possible unused
number).
The problem with this, as described in the previous patch dealing with
macvtap device naming, is that it makes "immediate reuse" of a newly
freed tap device name *much* more common, and in the aftermath of
deleting a tap device, there is some other necessary cleanup of things
which are named based on the device name (nwfilter rules, bandwidth
rules, OVS switch ports, to name a few) that could end up stomping
over the top of the setup of a new device of the same name for a
different guest.
Since the kernel "create a name based on a template" functionality for
tap devices doesn't exist for macvtap, this patch for standard tap
devices is a bit different from the previous patch for macvtap - in
particular there was no previous "bitmap ID reservation system" or
overly-complex retry loop that needed to be removed. We simply find
and unused name, and pass that name on to the kernel instead of
"vnet%d".
This counter is also wrapped when either it gets to INT_MAX or if the
full name would overflow IFNAMSIZ-1 characters. In the case of
"vnet%d" and a 32 bit int, we would reach INT_MAX first, but possibly
someday someone will change the name from vnet to something else.
(NB: It is still possible for a user to provide their own
parameterized template name (e.g. "mytap%d") in the XML, and libvirt
will just pass that through to the kernel as it always has.)

Subject: [PATCH] util: call iptables directly rather than via firewalld
When libvirt added support for firewalld, we were unable to use
firewalld's higher level rules, because they weren't detailed enough
and could not be applied to the iptables FORWARD or OUTPUT chains
(only to the INPUT chain). Instead we changed our code so that rather
than running the iptables/ip6tables/ebtables binaries ourselves, we
would send these commands to firewalld as "passthrough commands", and
firewalld would run the appropriate program on our behalf.
This was done under the assumption that firewalld was somehow tracking
all these rules, and that this tracking was benefitting proper
operation of firewalld and the system in general.
Several years later this came up in a discussion on IRC, and we
learned from the firewalld developers that, in fact, adding iptables
and ebtables rules with firewalld's passthrough commands actually has
*no* advantage; firewalld doesn't keep track of these rules in any
way, and doesn't use them to tailor the construction of its own rules.
Meanwhile, users have been complaining for some time that whenever
firewalld is restarted on a system with libvirt virtual networks
and/or nwfilter rules active, the system logs would be flooded with
warning messages whining that [lots of different rules] could not be
deleted because they didn't exist. For example:
firewalld[3536040]: WARNING: COMMAND_FAILED:
'/usr/sbin/iptables -w10 -w --table filter --delete LIBVIRT_OUT
--out-interface virbr4 --protocol udp --destination-port 68
--jump ACCEPT' failed: iptables: Bad rule
(does a matching rule exist in that chain?).
See:
https://bugzilla.redhat.com/1607929 (RHEL8)
https://bugzilla.redhat.com/1790837 (RHEL8-AV)
for many more examples and a discussion)
Note that these messages are created by iptables, but are logged by
firewalld - when an iptables/ebtables command fails, firewalld grabs
whatever is in stderr of the program, and spits it out to the system
log as a warning. We've requested that firewalld not do this (and
instead leave it up to the calling application to do the appropriate
logging), but this request has been respectfully denied.
But combining the two problems above ( 1) firewalld doesn't do
anything useful when you use it as a proxy to add/remove iptables
rules, 2) firewalld often insists on logging lots of
annoying/misleading/useless "error" messages when you use it as a
proxy to remove iptables rules that don't already exist), leads to a
solution - simply stop using firewalld to add and remove iptables
rules. Instead, exec iptables/ip6tables/ebtables directly in the same
way we do when firewalld isn't active.
We still need to keep track of whether or not firewalld is active, as
there are some things that must be done, e.g. we need to add some
actual firewalld rules in the firewalld "libvirt" zone, and we need to
take notice when firewalld restarts, so that we can reload all our
rules.
This patch doesn't remove the infrastructure that allows having
different firewall backends that perform their functions in different
ways, as that will very possibly come in handy in the future when we
want to have an nftables direct backend, and possibly a "pure"
firewalld backend (now that firewalld supports more complex rules, and
can add those rules to the FORWARD and OUTPUT chains). Instead, it
just changes the action when the selected backend is "firewalld" so
that it adds rules directly rather than through firewalld, while
leaving as much of the existing code intact as possible.
In order for tests to still pass, virfirewalltest also had to be
modified to behave in a different way (i.e. by capturing the generated
commandline as it does for the DIRECT backend, rather than capturing
dbus messages using a mocked dbus API).

Subject: [PATCH] util: fix typo in VIR_MOCK_WRAP_RET_ARGS()
When virfirewalltest.c was first written in commit 3a0ca7de51 (March
2013), a conditional accidentally tested for "ipv4" instead of
"ipv6". Since the file ended up only testing ipv4 rules, this has
never made any difference in practice, but I'm making some other
changes in this file and just couldn't let it stand :-)

Subject: [PATCH] util: replace macvtap name reservation bitmap with a simple
counter
There have been some reports that, due to libvirt always trying to
assign the lowest numbered macvtap / tap device name possible, a new
guest would sometimes be started using the same tap device name as
previously used by another guest that is in the process of being
destroyed *as the new guest is starting.
In some cases this has led to, for example, the old guest's
qemuProcessStop() code deleting a port from an OVS switch that had
just been re-added by the new guest (because the port name is based on
only the device name using the port). Similar problems can happen (and
I believe have) with nwfilter rules and bandwidth rules (which are
both instantiated based on the name of the tap device).
A couple patches have been previously proposed to change the ordering
of startup and shutdown processing, or to put a mutex around
everything related to the tap/macvtap device name usage, but in the
end no matter what you do there will still be possible holes, because
the device could be deleted outside libvirt's control (for example,
regular tap devices are automatically deleted when the qemu process
terminates, and that isn't always initiated by libvirt but could
instead happen completely asynchronously - libvirt then has no control
over the ordering of shutdown operations, and no opportunity to
protect it with a mutex.)
But this only happens if a new device is created at the same time as
one is being deleted. We can effectively eliminate the chance of this
happening if we end the practice of always looking for the lowest
numbered available device name, and instead just keep an integer that
is incremented each time we need a new device name. At some point it
will need to wrap back around to 0 (in order to avoid the IFNAMSIZ 15
character limit if nothing else), and we can't guarantee that the new
name really will be the *least* recently used name, but "math"
suggests that it will be *much* less common that we'll try to re-use
the *most* recently used name.
This patch implements such a counter for macvtap/macvlan, replacing
the existing, and much more complicated, "ID reservation" system. The
counter is set according to whatever macvtap/macvlan devices are
already in use by guests when libvirtd is started, incremented each
time a new device name is needed, and wraps back to 0 when either
INT_MAX is reached, or when the resulting device name would be longer
than IFNAMSIZ-1 characters (which actually is what happens when the
template for the device name is "maccvtap%d"). The result is that no
macvtap name will be re-used until the host has created (and possibly
destroyed) 99,999,999 devices.

Subject: [PATCH] util: synchronize with firewalld before we start calling
iptables directly
When it is starting up, firewalld will delete all existing iptables
rules and chains before adding its own rules. If libvirtd were to try
to directly add iptables rules during the time before firewalld has
finished initializing, firewalld would end up deleting the rules that
libvirtd has just added.
Currently this isn't a problem, since libvirtd only adds iptables
rules via the firewalld "passthrough command" API, and so firewalld is
able to properly serialize everything. However, we will soon be
changing libvirtd to add its iptables and ebtables rules by directly
calling iptables/ebtables rather than via firewalld, thus removing the
serialization of libvirtd adding rules vs. firewalld deleting rules.
This will especially apparent (if we don't fix it in advance, as this
patch does) when libvirtd is responding to the dbus NameOwnerChanged
event, which is used to learn when firewalld has been restarted. In
that case, dbus sends the event before firewalld has been able to
complete its initialization, so when libvirt responds to the event by
adding back its iptables rules (with direct calls to
/usr/bin/iptables), some of those rules are added before firewalld has
a chance to do its "remove everything" startup protocol. The usual
result of this is that libvirt will successfully add its private
chains (e.g. LIBVIRT_INP, etc), but then fail when it tries to add a
rule jumping to one of those chains (because in the interim, firewalld
has deleted the new chains).
The solution is for libvirt to preface it's direct calling to iptables
with a iptables command sent via firewalld's passthrough command
API. Since commands sent to firewalld are completed synchronously, and
since firewalld won't service them until it has completed its own
initialization, this will assure that by the time libvirt starts
calling iptables to add rules, that firewalld will not be following up
by deleting any of those rules.
To minimize the amount of extra overhead, we request the simplest
iptables command possible: "iptables -V" (and aside from logging a
debug message, we ignore the result, for good measure).
(This patch is being done *before* the patch that switches to calling
iptables directly, so that everything will function properly with any
fractional part of the series applied).

Subject: [PATCH] util/tests: enable locking on iptables/ebtables commandlines
by default
iptables and ip6tables have had a "-w" commandline option to grab a
systemwide lock that prevents two iptables invocations from modifying
the iptables chains since 2013 (upstream commit 93587a04 in
iptables-1.4.20). Similarly, ebtables has had a "--concurrent"
commandline option for the same purpose since 2011 (in the upstream
ebtables commit f9b4bcb93, which was present in ebtables-2.0.10.4).
Libvirt added code to conditionally use the commandline option for
iptables/ip6tables in upstream commit ba95426d6f (libvirt-1.2.0,
November 2013), and for ebtables in upstream commit dc33e6e4a5
(libvirt-1.2.11, November 2014) (the latter actually *re*-added the
locking for iptables/ip6tables, as it had accidentally been removed
during a refactor of firewall code in the interim).
I say "conditionally" because a check was made during firewall module
initialization that tried executing a test command with the
-w/--concurrent option, and only continued using it for actual
commands if that test command completed successfully. At the time the
code was added this was a reasonable thing to do, as it had been less
than a year since introduction of -w to iptables, so many distros
supported by libvirt were still using iptables (and possibly even
ebtables) versions too old to have the new commandline options.
It is now 2020, and as far as I can discern from repology.org (and
manually examining a RHEL7.9 system), every version of every distro
that is supported by libvirt now uses new enough versions of both
iptables and ebtables that they all have support for -w/--concurrent.
That means we can finally remove the conditional code and simply
always use them.

Subject: [PATCH] util: virhostcpu: Fail when fetching CPU Stats for invalid
cpu
virHostCPUGetStatsLinux walks through every cpu in /proc/stat until it
finds cpu%cpuNum that matches with the requested cpu.
If none is found it logs the error but it should return -1, instead of 0.
Otherwise virsh nodecpustats --cpu <invalid cpu number> and API bindings
don't fail properly, printing a blank line instead of an error message.
This patch also includes an additional test for virhostcputest to avoid
this regression to happen again in the future.

Subject: [PATCH] vircgroup: enforce range limit for cpu.shares
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Before the conversion to using systemd DBus API to set the cpu.shares
there was some magic conversion done by kernel which was documented in
virsh manpage as well. Now systemd errors out if the value is out of
range.
Since we enforce the range for other cpu cgroup attributes 'quota' and
'period' it makes sense to do the same for 'shares' as well.

Subject: [PATCH] vircgroup: fix cpu quota maximum limit
Kernel commit <d505b8af58912ae1e1a211fabc9995b19bd40828> added proper
check for cpu quota maximum limit to prevent internal overflow.
Even though this change is not present in all kernels it makes sense
to enforce the same limit in libvirt.

Subject: [PATCH] vircgroup: introduce nested cgroup to properly work with
systemd
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When running on host with systemd we register VMs with machined.
In this case systemd creates the root VM cgroup for us. This has some
implications where one of them is that systemd owns all files inside
the root VM cgroup and we should not touch them.
We already use DBus calls for some of the APIs but for the remaining
ones we will continue accessing the files directly. Systemd doesn't
support threaded cgroups so we need to do this.
The reason why we don't use DBus for most of the APIs is that we already
have a code that works with files and we would have to check if systemd
supports each API.
This change introduces new topology on systemd hosts:
$ROOT
|
+- machine.slice
|
+- machine-qemu\x2d1\x2dvm1.scope
|
+- libvirt
|
+- emulator
+- vcpu0
+- vcpu0
compared to the previous topology:
$ROOT
|
+- machine.slice
|
+- machine-qemu\x2d1\x2dvm1.scope
|
+- emulator
+- vcpu0

Subject: [PATCH] vircgroup: use DBus call to systemd for some APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When running on host with systemd we register VMs with machined.
In this case systemd creates the root VM cgroup for us. This has some
implications where one of them is that systemd owns all files inside
the root VM cgroup and we should not touch them.
If we change any value in file that systemd knows about it will be
changed to what systemd thinks it should be when executing
`systemctl daemon-reload`.
These are the APIs that we need to call using systemd because they set
limits that are proportional to sibling cgroups.

When we create a new child cgroup and the parent cgroup has any process
attached to it enabling controllers for the child cgroup fails with
error. We need to move the process into the child cgroup first before
enabling any controllers.

Subject: [PATCH] vircgroupv2: properly detect placement of running VM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When libvirtd starts a VM it internally stores a path to the main
cgroup. When we restart libvirtd we should get to the same state.
When we start a VM on host with systemd the cgroup is created for us and
the process is already placed into that cgroup and we detect the path
created by systemd using /proc/$PID/cgroup. After that we create
sub-cgroups and move all threads there.
Once libvirtd is restarted we again detect the cgroup path using
/proc/$PID/cgroup, but in this case we will get a different path because
the main thread was moved to a "emulator" cgroup.
Instead of ignoring the "emulator" directory when validating cgroups
remove it completely when detecting cgroup otherwise cgroups will not
work properly when libvirtd is restarted.

Subject: [PATCH] virhostcpu.c: fix 'die_id' parsing for Power hosts
Commit 7b79ee2f78 makes assumptions about die_id parsing in
the sysfs that aren't true for Power hosts. In both Power8
and Power9, running 5.6 and 4.18 kernel respectively,
'die_id' is set to -1:
$ cat /sys/devices/system/cpu/cpu0/topology/die_id
-1
This breaks virHostCPUGetDie() parsing because it is trying to
retrieve an unsigned integer, causing problems during VM start:
virFileReadValueUint:4128 : internal error: Invalid unsigned integer
value '-1' in file '/sys/devices/system/cpu/cpu0/topology/die_id'
This isn't necessarily a PowerPC only behavior. Linux kernel commit
0e344d8c70 added in the former Documentation/cputopology.txt, now
Documentation/admin-guide/cputopology.rst, that:
To be consistent on all architectures, include/linux/topology.h
provides default definitions for any of the above macros that are
not defined by include/asm-XXX/topology.h:
1) topology_physical_package_id: -1
2) topology_die_id: -1
(...)
This means that it might be expected that an architecture that
does not implement the die_id element will mark it as -1 in
sysfs.
It is not required to change die_id implementation from uInt to
Int because of that. Instead, let's change the parsing of the
die_id in virHostCPUGetDie() to read an integer value and, in
case it's -1, default it to zero like in case of file not found.
This is enough to solve the issue Power hosts are experiencing.
