562fc02ac1 conf: virtiofs: add rlimit_nofile element
Add an element to configure the rlimit nofile size:

...
<binary>
  <rlimit_nofile size='122333'/>
</binary>
...

Non-positive values are forbidden in 'domaincommon.rng'. Added separate
test file, created by modifying the 'vhost-user-fs-fd-memory.xml'.

Now that we have a fake virtiofsd json descriptor in our vhost-user
test data, we can remove the explicitly specified binary and our
mocking will ensure this test won't be affected by the host state.

Also remove the locking options, since they were never supported
by the Rust version of virtiofsd.

cf934c87cc network: allow "modify" option for DNS-Srv records
The "modify" command allows to replace an existing Srv record
(some of its elements respectively: port, priority and weight).
The primary key used to choose the modify record is the remaining
parameters, only one of them is required. Not using some of these

logic is there because of the previous implementation (Add and
Delete options) in the function.

70e826ec6a conf: Fix rawio/sgio checks for non-scsi hostdev devices
The current hostdev parsing logic sets rawio or sgio even if the hostdev type
is not 'scsi'. The rawio field in virDomainHostdevSubsysSCSI overlaps with
wwpn field in virDomainHostdevSubsysSCSIVHost, consequently setting a bogus
pointer value such as 0x1 or 0x2 from virDomainHostdevSubsysSCSIVHost's
point of view. This leads to a segmentation fault when it attempts to free
wwpn.

While setting sgio does not appear to crash, it shares the same flawed logic
as setting rawio.

Instead, we ensure these are set only after the hostdev type check succeeds.
This patch also adds two test cases to exercise both scenarios.

d00816209e qemu_capabilities: Probe SEV capabilities even for QEMU_CAPS_SEV_SNP_GUEST
While it's very unlikely to have QEMU that supports SEV-SNP but
doesn't support plain SEV, for completeness sake we ought to
query SEV capabilities if QEMU supports either. And similarly to
QEMU_CAPS_SEV_GUEST we need to clear the capability if talking to
QEMU proves SEV is not really supported.

This in turn removes the 'sev-snp-guest' capability from one of
our test cases as Peter's machine he uses to refresh capabilities
is not SEV capable. But that's okay. It's consistent with
'sev-guest' capability.

af437d2d64 qemu: Don't specify vfio-pci.ramfb when ramfb is false
Commit 7c8e606b64 attempted to fix
the specification of the ramfb property for vfio-pci devices, but it
failed when ramfb is explicitly set to 'off'. This is because only the
'vfio-pci-nohotplug' device supports the 'ramfb' property. Since we use
the base 'vfio-pci' device unless ramfb is enabled, attempting to set
the 'ramfb' parameter to 'off' this will result in an error like the
following:

  error: internal error: QEMU unexpectedly closed the monitor
  (vm='rhel'): 2024-06-06T04:43:22.896795Z qemu-kvm: -device

  ","ramfb":false,"bus":"pci.7","addr":"0x0"}: Property 'vfio-pci.ramfb'
  not found.

This also more closely matches what is done for mdev devices.

aabf279ca0 tests: fix broken nftables test data so that individual tests are successful
When the chain names and table name used by the nftables firewall
backend were changed in commit
958aa7f274, I forgot to change the test
data file base.nftables, which has the extra "list" and "add
chain/table" commands that are generated for the first test case of
networkxml2firewalltest.c. When the full set of tests is run, the
first test will be an iptables test case, so those extra commands
won't be added to any of the nftables cases, and so the data in
base.nftables never matches, and the tests are all successful.

However, if the test are limited with, e.g. VIR_TEST_RANGE=2 (test #2
will be the nftables version of the 1st test case), then the commands
to add nftables table/chains *will* be generated in the test output,
and so the test will fail. Because I was only running the entire test
series after the initial commits of nftables tests, I didn't notice
this. Until now.

base.nftables has now been updated to reflect the current names for
chains/table, and running individual test cases is once again
successful.

 - 9.1 machine type added
 - 'SierraForest' cpu type added
 - 'SapphireRapids-v3-x86_64-cpu' added
 - 'VFIO_MIGRATION' event added (and corresponding 'migration-events'
   bool for the device
 - 'exit-on-error' argument for 'migrate-incoming' added
 - 'sev-guest' gained 'legacy-vm-type' boolean
 - cpu topology added 'module' fields
 - 'compat-props' argument 'query-machines' added
 - 'deprecated-props' argument for 'query-cpu-model-expansion' added

Deprecated removals:
 - legacy non-shared-storage migration fully removed (config/stats)
 - legacy migration compression fully removed
 - RDMA support removed
 - dropped 'nios2' field type from 'query-cpus-fast' return data

Note that this dump was done on a newer kernel version which resulted in
the 'pcommit' feature being removed from the few test cases which depend
on the real CPU flag dump.

a4f38f6ffe network: use iif/oif instead of iifname/oifname in nftables rules
iifname/oifname need to lookup the string that contains the name of
the interface each time a packet is checked, while iif/oif compare the
ifindex of the interface, which is included directly in the
packet. Conveniently, the rule is created using the *name* of the
interface (which gets converted to ifindex as the rule is added), so
no extra work is required other than changing the commandline option.

If it was the case that the interface could be deleted and re-added
during the life of the rule, we would have to use Xifname (since
deleting and re-adding the interface would result in ifindex
changing), but for our uses this never happens, so Xif works for us,
and undoubtedly improves performance by at least 0.0000001%.

f63cbc7365 virGetGroupList: Refactor and fix callers
Use contemporary style for declarations and automatic memory clearing
for a helper string.

Since the function can't fail any more, remove any mention of returning
errno and remove error checks from all callers.

afbd1bb89e network: eliminate pointless host input/output rules from nftables backend
The iptables backend (which was used as the model for the nftables
backend) used the same "filter" and "nat" tables used by other
services on the system (e.g. firewalld or any other host firewall
management application), so it was possible that one of those other
services would be blocking DNS, DHCP, or TFTP from guests to the host;
we added our own rules at the beginning of the chain to allow this
traffic no matter if someone else rejected it later.

But with nftables, each service uses their own table, and all traffic
must be acepted by all tables no matter what - it's not possible for
us to just insert a higher priority/earlier rule that will override
some reject rule put in by, e.g., firewalld. Instead the firewalld (or
other) table must be setup by that service to allow the traffic. That,
along with the fact that our table is already "accept by default",
makes it possible to eliminate the individual accept rules for DHCP,
DNS, and TFTP. And once those rules are eliminated, there is no longer
any need for the guest_to_host or host_to_guest tables.

958aa7f274 network: rename chains used by network driver nftables backend
Because the chains added by the network driver nftables backend will
go into a table used only by libvirt, we don't need to have "libvirt"
in the chain names. Instead, we can make them more descriptive and
less abrasive (by using lower case, and using full words rather than
abbreviations).

Also (again because nobody else is using the private "libvirt_network"
table) we can directly put our rules into the input ("guest_to_host"),
output ("host_to_guest"), and postrouting ("guest_nat") chains rather
than creating a subordinate chain as done in the iptables backend.

0bd7a47356 network: name the nftables table "libvirt_network" rather than "libvirt"
This way when we implement nftables for the nwfilter driver, we can
create a separate table called "libvirt_nwfilter" and everything will
look all symmetrical and stuff.

f341bdee8d tests: test cases for nftables backend
Run all the networkxml2firewall tests twice - once with iptables
backend, and once with the nftables backend.

The results files for the existing iptables tests were previously
named *.args. That has been changed to *.iptables, and the results
files for the new nftables tests are named *.nftables.
