3fff8c91b0 network: introduce a "none" firewall backend type
There are two scenarios identified after the recent firewall backend
selection was introduced, which result in libvirtd failing to startup
due to an inability to find either iptables/nftables

 - On Linux if running unprivileged with $PATH lacking the dir
   containing iptables/nftables
 - On non-Linux where iptables/nftables never existed

In the former case, it is preferrable to restore the behaviour whereby
the driver starts successfully. Users will get an error reported when
attempting to start any virtual network, due to the lack of permissions
needed to create bridge devices. This makes the missing firewall backend
irrelevant.

In the latter case, the network driver calls the 'nop' platform
implementation which does not attempt to implement any firewall logic,
just allowing the network to start without firewall rules.

To solve this are number of changes are required

 * Introduce VIR_FIREWALL_BACKEND_NONE, which does nothing except
   report a fatal error from virFirewallApply(). This code path
   is unreachable, since we'll never create a virFirewall
   object with with VIR_FIREWALL_BACKEND_NONE, so the error reporting
   is just a sanity check.

 * Ignore the compile time backend defaults and assume use of
   the 'none' backend if running unprivileged.

   This fixes the first regression, avoiding the failure to start
   libvirtd on Linux in unprivileged context, instead allowing use
   of the driver and expecting a permission denied when creating a
   bridge.

 * Reject the use of compile time backend defaults no non-Linux
   and hardcode the 'none' backend. The non-Linux platforms have
   no firewall implementation at all currently, so there's no
   reason to permit the use of 'firewall_backend_priority'
   meson option.

   This fixes the second regression, avoiding the failure to start
   libvirtd on non-Linux hosts due to non-existant Linux binaries.

 * Change the Linux platform backend to raise an error if the
   firewall backend is 'none'. Again this code path is unreachable
   by default since we'll fail to create the bridge before getting
   here, but if someone modified network.conf to request the 'none'
   backend, this will stop further progress.

 * Change the nop platform backend to raise an error if the
   firewall backend is 'iptables' or 'nftables'. Again this code
   path is unreachable, since we should already have failed to
   find the iptables/nftables binaries on non-Linux hosts, so
   this is just a sanity check.

 * 'none' is not permited as a value in 'firewall_backend_priority'
   meson option, since it is conceptually meaningless to ask for
   that on Linux.

NB, 'firewall_backend_priority' allows repeated options temporarily,
which we don't want. Meson intends to turn this into a hard error

  DEPRECATION: Duplicated values in array option is deprecated. This will become a hard error in the future.

and we can live with the reduced error checking until that happens.

957eea376b meson: Improve default firewall backend configuration
The current implementation requires users to configure the
preference as such:

  -Dfirewall_backend_default_1=iptables
  -Dfirewall_backend_default_2=nftables

In addition to being more verbose than one would hope, there
are several things that could go wrong.

First of all, meson performs no validation on the provided
values, so mistakes will only be caught by the compiler.
Additionally, it's entirely possible to provide nonsensical
combinations, such as repeating the same value twice.

Change things so that the preference can now be configured
as such:

  -Dfirewall_backend_priority=iptables,nftables

Checks have been added to prevent invalid values from being
accepted.

b89c4991da network: add an nftables backend for network driver's firewall construction
Support using nftables to setup the firewall for each virtual network,
rather than iptables. The initial implementation of the nftables
backend creates (almost) exactly the same ruleset as the iptables
backend, determined by running the following commands on a host that
has an active virtual network:

  iptables-save >iptables.txt
  iptables-restore-translate -f iptables.txt

(and the similar ip6tables-save/ip6tables-restore-translate for an
IPv6 network). Correctness of the new backend was checked by comparing
the output of:

  nft list ruleset

when the backend is set to iptables and when it is set to nftables.

This page was used as a guide:

  https://wiki.nftables.org/wiki-nftables/index.php/Moving_from_iptables_to_nftables

The only differences between the rules created by the nftables backed
vs. the iptables backend (aside from a few inconsequential changes in
display order of some chains/options) are:

1) When we add nftables rules, rather than adding them in the
system-created "filter" and "nat" tables, we add them in a private
table (ie only we should be using it) created by us called "libvirt"
(the system-created "filter" and "nat" tables can't be used because
adding any rules to those tables directly with nft will cause failure
of any legacy application attempting to use iptables when it tries to
list the iptables rules (e.g. "iptables -S").

(NB: in nftables only a single table is required for both nat and
filter rules - the chains for each are differentiated by specifying
different "hook" locations for the toplevel chain of each)

2) Since the rules that were added to allow tftp/dns/dhcp traffic from
the guests to the host are unnecessary in the context of nftables,
those rules aren't added.

(Longer explanation: In the case of iptables, all rules were in a
single table, and it was always assumed that there would be some
"catch-all" REJECT rule added by "someone else" in the case that a
packet didn't match any specific rules, so libvirt added these
specific rules to ensure that, no matter what other rules were added
by any other subsystem, the guests would still have functional
tftp/dns/dhcp. For nftables though, the rules added by each subsystem
are in a separate table, and in order for traffic to be accepted, it
must be accepted by *all* tables, so just adding the specific rules to
libvirt's table doesn't help anything (as the default for the libvirt
table is ACCEPT anyway) and it just isn't practical/possible for
libvirt to find *all* other tables and add rules in all of them to
make sure the traffic is accepted. libvirt does this for firewalld (it
creates a "libvirt" zone that allows tftp/dns/dhcp, and adds all
virtual network bridges to that zone), however, so in that case no
extra work is required of the sysadmin.)

3) nftables doesn't support the "checksum mangle" rule (or any
equivalent functionality) that we have historically added to our
iptables rules, so the nftables rules we add have nothing related to
checksum mangling.

(NB: The result of (3) is that if you a) have a very old guest (RHEL5
era or earlier) and b) that guest is using a virtio-net network
device, and c) the virtio-net device is using vhost packet processing
(the default) then DHCP on the guest will fail. You can work around
this by adding <driver name='qemu'/> to the <interface> XML for the
guest).

There are certainly much better nftables rulesets that could be used
instead of those implemented here, and everything is in place to make
future changes to the rules that are used simple and free of surprises
(e.g. the rules that are added have coresponding "removal" commands
added to the network status so that we will always remove exactly the
rules that were previously added rather than trying to remove the
rules that "the current build of libvirt would have added" (which will
be incorrect the first time we run a libvirt with a newly modified
ruleset). For this initial implementation though, I wanted the
nftables rules to be as identical to the iptables rules as possible,
just to make it easier to verify that everything is working.

The backend can be manually chosen using the firewall_backend setting
in /etc/libvirt/network.conf. libvirtd/virtnetworkd will read this
setting when it starts; if there is no explicit setting, it will check
for availability of FIREWALL_BACKEND_DEFAULT_1 and then
FIREWALL_BACKEND_DEFAULT_2 (which are set at build time in
meson_options.txt or by adding -Dfirewall_backend_default_n=blah to
the meson commandline), and use the first backend that is available
(ie, that has the necessary programs installed). The standard
meson_options.txt is set to check for nftables first, and then
iptables.

Although it should be very safe to change the default backend from
iptables to nftables, that change is left for a later patch, to show
how the change in default can be undone if someone really needs to do
that.

865eea30f4 meson: stop looking for iptables/ip6tables/ebtables at build time
This was the only reason we required the iptables and ebtables
packages at build time, and many other external commands already have
their binaries found at runtime by looking through $PATH (virCommand
automatically does this), so we may as well do it for these commands
as well.

Since we no longer need iptables or iptables at build time, we can
also drop the BuildRequires for them from the rpm specfile.

64b966558c network: support setting firewallBackend from network.conf
It still can have only one useful value ("iptables"), but once a 2nd
value is supported, it will be selectable by setting
"firewall_backend=nftables" in /etc/libvirt/network.conf.

If firewall_backend isn't set in network.conf, then libvirt will check
to see if FIREWALL_BACKEND_DEFAULT_1 is available and, if so, set
that. (Since FIREWALL_BACKEND_DEFAULT_1 is currently "iptables", this
means checking to see it the iptables binary is present on the
system).  If the default backend isn't available, that is considered a
fatal error (since no networks can be started anyway), so an error is
logged and startup of the network driver fails.

NB: network.conf is itself created from network.conf.in at build time,
and the advertised default setting of firewall_backend (in a commented
out line) is set from the meson_options.txt setting
"firewall_backend_default_1". This way the conf file will have correct
information no matter what ordering is chosen for default backend at
build time (as more backends are added, settings will be added for
"firewall_backend_default_n", and those will be settable in
meson_options.txt and on the meson commandline to change the ordering
of the auto-detection when no backend is set in network.conf).

virNetworkLoadDriverConfig() may look more complicated than necessary,
but as additional backends are added, it will be easier to add checks
for those backends (and to re-order the checks based on builders'
preferences).

9c1cfc337e meson: Bump glib version to 2.58.0
Now that we don't have any distro stuck with glib-2.56.0, we can
bump the glib version. In fact, this is needed, because of
g_clear_pointer. Since v7.4.0-rc1~301 we declare at compile time
what version of glib APIs we want to use (by setting
GLIB_VERSION_MIN_REQUIRED = GLIB_VERSION_MAX_ALLOWED = 2.56.0),
regardless of actual glib version in the host.

And since we currently require glib-2.56.0 and force glib to use
APIs of that version, some newer bits are slipping from us. For
instance: regular function version of g_clear_pointer() is used
instead of a fancy macro. So what? Well, g_clear_pointer()
function typecasts passed free function to void (*)(void *) and
then calls it. Well, this triggers UBSAN, understandably. But
with glib-2.58.0 the g_clear_pointer() becomes a macro which
calls the free function directly, with no typecasting and thus no
undefined behavior.

3f5a1fa234 meson: Disable -fsanitize=function
Strictly speaking, xdrproc_t is declared as following:

  typedef bool_t (*xdrproc_t)(XDR *, ...);

But our rpcgen generates properly typed functions, e.g.:

  bool_t xdr_virNetMessageError(XDR *xdrs, virNetMessageError *objp)

Now, these functions of ours are passed around as callbacks (via
an argument of xdrproc_t type), for instance in
virNetMessageEncodePayload(). But these two types are strictly
different. We silence the compiler by typecasting the callbacks
when passing them, but strictly speaking - calling such callback
later, when a function of xdrproc_t is expected is an undefined
behavior.

Ideally, we would fix our rpcgen to generate proper function
headers, but: a) my brain is too small to do that, and b) we
would lose compiler protection if an xdr_*() function is called
directly but argument of a wrong type is passed.

Silence UBSAN for now.

0287b5dfd2 tools: Introduce SSH proxy
This allows users to SSH into a domain with a VSOCK device:

  ssh user@qemu/machineName

So far, only QEMU domains are supported AND qemu:///system is
looked for the first for 'machineName' followed by
qemu:///session. I took an inspiration from Systemd's ssh proxy
[1] [2].

To just work out of the box, it requires (yet unreleased) systemd
to be running inside the guest to set up a socket activated SSHD
on the VSOCK. Alternatively, users can set up the socket
activation themselves, or just run a socat that'll forward vsock
<-> TCP communication.

526e7ee15a meson: Restore check for sched_getaffinity()
Commit c07cf0a686 replaced this check with one for the
presence of cpu_set_t.

The idea at the time was that only sched_{get,set}affinity()
were visible by default, while making cpu_set_t visible required
defining _WITH_CPU_SET_T. So libvirt would detect the function
and attempt to use it, but the code would not compile because
the necessary data type had not been made accessible.

The commit in question brought three FreeBSD commits as evidence
of this. While [1] and [2] do indeed seem to support this
explanation, [3] from just a few days later made it so that not
just cpu_set_t, but also the functions, required user action to
be visible. This arguably would have made the change unnecessary.

However, [4] from roughly a month later changed things once
again: it completely removed _WITH_CPU_SET_T, making both the
functions and the data type visible by default.

This is the status quo that seems to have persisted until
today. If one were to check any recent FreeBSD build job
performed as part of our CI pipeline, for example [5] and [6]
for FreeBSD 13 and 14 respectively, they would be able to
confirm that in both cases cpu_set_t is detected as available.

Since there is no longer a difference between the availability
of the functions and that of the data type, go back to what we
had before.

This has the interesting side-effect of fixing a bug
introduced by the commit in question.

When detection was changed from the function to the data type,
most uses of WITH_SCHED_GETAFFINITY were replaced with uses of
WITH_DECL_CPU_SET_T, but not all of them: specifically, those
that decided whether qemuProcessInitCpuAffinity() would be
actually implemented or replaced with a no-op stub were not
updated, which means that we've been running the stub version
everywhere except on FreeBSD ever since.

The code has been copied to the Cloud Hypervisor driver in
the meantime, which is similarly affected. Now that we're
building the actual implementation, we need to add virnuma.h
to the includes.

As a nice bonus this also makes things work correctly on
GNU/Hurd, where cpu_set_t is available but
sched_{get,set}affinity() are non-working stubs.

7284b4cf8b meson: Adjust -fstack-protector use
Back in 2014, -fstack-protector was reported not to work on
aarch64, so fe881ae086 disabled it on that target. OS-wise,
its use is currently limited to just Linux, FreeBSD and Windows.

Looking at the situation today, it seems that whatever issue was
affecting aarch64 a decade ago has been resolved; moreover,
macOS can also use the feature these days.

I haven't checked any of the other BSDs, but since the feature
works on FreeBSD it's pretty safe to assume that they can use
it too. If we get reports that it's not the case, we can always
further restrict its usage accordingly.

9eabf14afb qemu: add runtime config option for nbdkit
Currently when we build with nbdkit support, libvirt will always try to
use nbdkit to access remote disk sources when it is available. But
without an up-to-date selinux policy allowing this, it will fail.
because the required selinux policies are not yet widely available, we
have disabled nbdkit support on rpm builds for all distributions before
Fedora 40.

Unfortunately, this makes it more difficult to test nbdkit support.
After someone updates to the necessary selinux policies, they would also
need to rebuild libvirt to enable nbdkit support. By introducing a
configure option (nbdkit_config_default), we can build packages with
nbdkit support but have it disabled by default.

9231566146 build: suppress "ignoring duplicate libraries" warning on macOS
Xcode 15, which provides the compiler toolchain for building libvirt
on macOS has switched to a new linker that warns about duplicated
"-lblah" options on the ld commandline. In practice this is impossible
to prevent in a large project, and also harmless.

Fortunately the new ld command also has an option,
-no_warn_duplicate_libraries, that supresses this harmless/pointless
warning, meson has a simple way to check if that option is supported,
and libvirt's meson.build files already have examples of adding an
option to the ld commandline if it's available.

87f14badd0 meson: Disable all tests when tests are disabled
Currently, passing -Dtests=disabled only disables a subset of
tests: those that are written in C and thus require compilation.
Other tests, such as the syntax-check ones and those that are
implemented as scripts, are always enabled.

There's a potentially dangerous consequence of this behavior:
when tests are disabled, 'meson test' will succeed as if they
had been enabled. No indication of this will be shown, so the
user will likely make the reasonable assumption that everything
is fine when in fact the significantly reduced coverage might
be hiding failures.

To solve this issues, disable *all* tests when asked to do so,
and inject an intentionally failing test to ensure that 'meson
test' doesn't succeed.
