[libvirt PATCH 00/28] native support for nftables in virtual network driver
by Laine Stump
This patch series enables libvirt to use nftables rules rather than
iptables *when setting up virtual networks* (it does *not* add
nftables support to the nwfilter driver). It accomplishes this by
abstracting several iptables functions (from viriptables.[ch] called
by the virtual network driver into a rudimentary "virNetfilter API"
(in virnetfilter.[ch], having the virtual network driver call the
virNetFilter API rather than calling the existing iptables functions
directly, and then finally adding an equivalent virNftables backend
that can be used instead of iptables (selected manually via a
network.conf setting, or automatically if iptables isn't found on the
host).
A first look at the result may have you thinking that it's filled with
a lot of bad decisions. While I would agree with that in many cases, I
think that overall they are the "least bad" decisions, or at least
"bad within acceptable limits / no worse than something else", and
point out that it's been done in a way that minimizes (actually
eliminates) the need for immediate changes to nwfilter (the other
consumer of iptables, which *also* needs to be updated to use native
nftables), and makes it much easier to change our mind about the
details in the future.
When I first started on this (long, protracted, repeatedly interrupted
for extended periods - many of these patches are > a year old) task, I
considered doing an all-at-once complete replacement of iptables with
nftables, since all the Linux distros we support have had nftables for
several years, and I'm pretty sure nobody has it disabled (not even
sure if it's possible to disable nftables while still enabling
iptables, since they both use xtables in the kernel). But due to
libvirt's use of "-t mangle -j CHECKSUM --checksum-fill" (see commit
fd5b15ff all the way back in July 2010 for details) which has no
equivalent in nftables rules (and we don't *want* it to!!), and the
desire to be able to easily switch back to iptables in case of an
unforeseen regression, we decided that both iptables and nftables need
to be supported (for now), with the default (for now) remaining as
iptables.
Just allowing for dual backends complicated matters, since it means
that we have to have a config file, a setting, detection of which
backends are available, and of course some sort of concept of an
abstracted frontend that can use either backend based on the config
setting (and/or auto-detection). Combining that with the fact that it
would just be "too big" of a project to switch over nwfilter's
iptables usage at the same time means that we have to keep around a
lot of existing code for compatibility's sake rather than just wiping
it all away and starting over.
So, what I've ended up with is:
1) a network.conf file (didn't exist before) with a single setting
"firewall_backend". If unset, the network driver tries to use iptables
on the backend, and if that's missing, then tries to use nftables.
2) a new (internal-only, so transient!) virNetFilterXXX API that is
used by the network driver in place of the iptablesXXX API, and calls
either iptablesXXX or:
3) a virNftablesXXX API that exactly replicates the filtering rules of
the existing iptablesXXX API (except in the custom "libvirt" base
table rather than the system "filter" and "nat" tables). This means
that:
4) when the nftables backend is used, the rules added are *exactly the
same* (functionally speaking) as we currently add for iptables (except
they are in the "libvirt" table).
We had spent some time in IRC discussing different ways of using new
functionality available in nftables to make a more
efficient/performant implemention of the desired filtering, and there
are some really great possibilities that need to be explored, but in
the end there were too many details up in the air, and I decided that
it would be more "accomplishable" (coined a new word there!) to first
replicate existing behavior with nftables, but do it inside a
framework that makes it easy to modify the details in the future (in
particular making it painless to switch back and forth between builds
with differing filter models at runtime) - this way we'll be able to
separate the infrastructure work from the details of the rules (which
we can then more easily work on and experiment with). (This implies
that the main objective right now is "get rid of iptables
dependencies", not "make the filtering faster and more efficient").
Notable features of this patchset:
* allows switching between iptables/nftables backends without
rebooting or restarting networks/guests.
Because the commands required to remove a network's filter rules are
now saved in the network status XML, each time libvirtd (or
virtnetworkd) is restarted, it will execute exactly the commands
needed to remove the filter rules that had been added by the
previous libvirtd/virtnetworkd (rather than just making a guess, as
we've always done up until now), and then add new rules using the
current backend+binary's set of rules (while also saving the info
needed for future removal of these new rules back into the network's
status XML).
* firewall_backend can be explicitly set in (new)
/etc/libvirt/network.conf, but if it's not explicitly set, libvirt
will default to the iptables backend if the iptables binary is
found, and otherwise fall back to nftables as long as the nft
binary is found; otherwise the first attempt to start a network will
fail with an appropriate error.
Things that seem ugly / that I would like to clean up / that I think
are just fine as they are:
* virFirewall does *not* provide a backend-agnostic interface [this is fine]
* We need to maintain a backward-compatible API for virFirewall so
that we don't have to touch nwfilter code. Trying to make its API
backend-agnostic would require individually considering/changing
every nwfilter use of virFirewall.
* instead virFirewall objects are just a way to build a collection
of commands to execute to build a firewall, then execute them
while collecting info for and building a collection of commands
that will tear down that firewall in the future.
Do I want to "fix" this in the future by making virFirewall a higher
level interface that accepts tokens describing the type of rule to
add (rather than backend-specific arguments to a backend-specific
command)? No. I think I like the way virFirewall works (as
described in that previous bullet-point), instead I'm thinking that
it is just slightly mis-named - I've lately been thinking of it as a
"virNetFilterCmdList". Similarly, the virFirewallRules that it has a
list of aren't really "rules", they are better described as commands
or actions, so maybe they should be renamed to virNetfilterCmd or
virNetfilterAction. But that is just cosmetic, so I didn't want to
get into it in these patches (especially in case someone disagrees,
or has a better idea for naming).
* Speaking of renaming - I should probably rename all the
"iptablesXXX" functions to "virIptablesXXX" to be consistent with so
much of our other code. I lost the ambition to deal with it right
now though, so I'm leaving that for later cleanup (or I could do it
now if it really makes someone's day :-).
* I could have chosen a higher place in the callchain to make the
virNetfilter abstraction, e.g. at the level of
"networkAddXXXFirewallRules()" rather than at the lower level of
iptablesXXX(). That is actually probably what will happen in the
future (since it will be necessary in order for an nftables-based
firewall to be significantly different in structure from an
iptables-based firewall). But that's the beauty of an API being
private - we can freely add/remove things as needed. the important
thing is that we now have the basic structure there.
For now, the split is just above the existing iptablesXXX API
(util/viriptables.[ch], which seems like a "narrow" enough
place. Most iptablesXXX functions are written in terms of just 10
*other* iptablesXXX functions that add iptables-specific commands -
I've just moved those functions into virnetfilter.[ch]
(appropriately renamed), and changed them to call the 10
virNetfilterXXX functions that will in-turn call those 10
iptablesXXX (or equivalent virNftablesXXX) functions.
* Some people may dislike that the 10 virNetfilterXXX functions are
each written with a switch statement that has cases to directly call
each backend, rather than each backend driver having a table of
pointers to API functions, with the virNetfilter API function
calling backends[fwBackend]->XXX() (ie the pattern for so many
drivers in libvirt). But for just 2 backends, that really seemed
like overkill and unnecessary obfuscation.
* As implemented here, I am storing a "<fwRemoval>" element in the
network status XML - it contains a serialized virFirewall object
that directly contains the commands necessary to remove the
firewall. I could instead just store "<firewall>", which would
include all the commands that were used to *create* the firewall in
addition to the commands needed to remove the firewall. The way it's
done currently takes up less space; switching to storing the full
firewall *might* be more informative to somebody, but on the other
hand would make the network status XML *very* long. If anybody has
an opinion about this, now is the time to bring it up - do you think
it's worth having a separate list of all the commands that were used
to create a network's firewall (keeping in mind that there is no
public API to access it)? Or is it enough to just store what's
needed to remove the firewall?
* Several months ago Eric Garver posted patches for a pure firewalld
backend, and I requested that they not be pushed because I wanted
that to be integrated with my nftables backend support. Due to the
fact that the firewalld backend is almost entirely implemented by
putting the bridge into a new firewalld "zone", with no individual
rules added, that won't happen as just another backend driver file
in parallel to iptables and nftables; it will instead work by
checking firewall_backend at a higher level in the network driver,
thus avoiding the calls to virNetfilterXXX() entirely. I have
locally merged Eric's patches over the top of these patches, and
there are surprisingly few conflicts, but since his patches didn't
account for a user-settable config (but instead just always used the
firewalld backend if firewalld was active), some of the patches are
going to require a bit of rework, which I'll take care of after
getting these patches in.

[libvirt PATCH 0/3] Introduce VIR_MIGRATE_ASSUME_SHARED_STORAGE
by Andrea Bolognani
This was initially motivated by a KubeVirt issue[1] concerning
integration with the Portworx storage provide, but it turns out to be
more generally applicable: since mounting an NFS share on the same
host that is exporting it is known to cause issues and is therefore
not recommended, we need a way to allow migration in such a
configuration while still not going quite as far as
VIR_MIGRATE_UNSAFE does and losing all handrails.

Versioned CPU types in libvirt
by Jonathon Jongsma
I'm currently looking at getting libvirt working with AMD's SEV-SNP
encrypted virtualization technology. I have access to a test machine
with an AMD EPYC 7713 processor which I can use to launch SNP guests
with qemu, but only when I specify one of the following versioned -cpu
values:
- EPYC-v4
- EPYC-Milan-v2
- EPYC-Rome-v3
From what I understand, the unversioned CPU models in qemu are supposed
to resolve to a specific versioned CPU model depending on the machine
type. But I'm not exactly sure how machine type influences it.
I've got some libvirt patches to launch an SEV-SNP guest working now
except for the CPU model specification. As far as I can tell, I can
currently only specify the un-versioned model in libvirt. Is there any
way to request a particular versioned CPU from qemu? I feel like I'm
missing something here.
I should perhaps also mention that I'm running a development version of
qemu from Cole's copr repo[1], which could still have some related bugs

[PATCH 00/16] Farewell rpcgen
by Daniel P. Berrangé
This series something I was hacking on a little while back in an
attempt to make our RPC layer more maintainable. There are many
aspects I'm unhappy about with current code
* When serializing a message we have no clue how big
it will be, but xdrmem_create wants a fixed size,
so we have to keep trying to serialize in a loop
making it bigger each time
* We don't control memory allocation/free'ing directly
so we can't do a virSecureErase on fields inside the
RPC message struct that handle secrets.
* The XDR API is generally unpleasant to use as it is
outside our virNetMessage object. Ideally we would
be reading/writing directly from/to the virNetMessage
buffer with APIs on virNetMessage,instead of indirectly
via a XDR object.
* We want more from XDR than it actually gives us. Our
XDR protocol files have annotations to express what
we want our code generator todo, or for ACLs. The
relationship between the structs and the message
numbers is implicit. Essentially we've defined our
own language indirectly via comments, and then
parse this with regexes which is horrid.
* The code rpcgen creates is poor quality which we have
to post-process to fix bugs/problems. It also lacks
support for modern features like g_auto.
Anyway, in a fit of rage I looked at the XDR RFC and thought..
This language is trivial, why do we need to outsource to
rpcgen and libtirpc instead of dealing with it directly.
This small series moves in that direction. It creates an
XDR language lexer and parser, and then a code generator
which emits code that is (nearly) identical to what rpcgen
would emit. This is sufficient to eliminate rpcgen usage
and support g_auto. Since we're still using libtirpc
at this stage we can be confident we're still doing the
same thing on the wire. I've got some unit tests too
with the rpcgen generation to validate stuff.
The next step is to change the code generator so that
instead of generating code for libtirpc APIs, it will
instead directly speak virNetMessage APIs. That would
give us full control over our RPC stack guaranteed to
be platform portable instead of fighting slight differences
in RPC libraries (eg xdr_quad vs xdr_int64 madness).
I was going to wait until I had written such code before
sending this series, but I've got diverted onto other more
important tasks. So here at least is what I have so far.
After that foundation is done, we are in a place where
we can actually do more innovative things. For example
we can directly extend the XDR protocol language if we
like, turning our magic comments into properly parsable
constructs.
With this, we would be in a position to replace our
Perl RPC client/server dispatch code generators with
something that is more supportable in Python. The python
code would work with properly represented objects and
formal parsers and not regexes and anonymous complex
perl data structures.

ANNOUNCE: Mailing list move complete
by Daniel P. Berrangé
This is an announcement to the effect that the mailing list move is now
complete. TL;DR the new list addresses are:
* announce(a)lists.libvirt.org (formerly libvirt-announce(a)redhat.com)
Low volume, announcements of releases and other important info
* users(a)lists.libvirt.org (formerly libvirt-users(a)redhat.com)
End user questions and discussions and collaboration
* devel(a)lists.libvirt.org (formerly libvir-list(a)redhat.com)
Patch submission for development of main project
* security(a)lists.libvirt.org (formerly libvir-security(a)redhat.com)
Submission of security sensitive bug reports
The online archive and membership mgmt interface is
https://lists.libvirt.org
In my original announcement[1] I mentioned that people would need to manually
re-subscribe. Due to a mixup in communications, our IT admins went ahead and
migrated across the existing entire subscriber base for all lists. Thus there
is NO need to re-subscribe to any of the lists. If you were doing filtering
of mail, you may need to update filters for the new list ID matches.
With the new list server, HyperKitty is providing the web interface. Thus
if you wish to interact with the lists entire via the browser this is now
possible. Note that it requires you to register for an account and set a
password, even if you are already a list subscriber.
If you mistakenly send to the old lists you should receive an auto-reply
about the moved destinations.
Note, we had some technical issues on Thursday/Friday, so if you sent
mails on those two days they probably will not have reached any lists,
and so you may wish to re-send them.
With regards,
Daniel

RFC: Switch to a date-based versioning scheme
by Andrea Bolognani
Since we're just a few months away from the 10.0.0 release, I thought
it would be a good time to bring up this idea.
Can we move to date-based version numbers? I suggest having
libvirt 24.01.0 instead of 10.0.0
24.03.0 10.1.0
24.04.0 10.2.0
...
24.11.0 10.9.0
24.12.0 10.10.0
The big advantage is that, once version numbers are obviously
date-based, any expectation of them being interpreted according to
semver[1] are immediately gone.
Of course semver doesn't make sense for us, given our extremely
strong backwards compatibility guarantees, and that's exactly why
we've left it behind with 2.0.0; however, that's something that's not
immediately obvious to someone who's not very involved with our
development process, and regarless of our intentions libvirt version
numbers *will* be mistakenly assumed to be semver-compliant on
occasion.
People are quite used to date-based version numbers thanks to Ubuntu
having used them for almost two decades, so I don't think anyone is
going to be confused by the move. And since our release schedule is
already date-based, having the versioning scheme match that just
makes perfect sense IMO.
Up until now, one could have argued in favor of the current
versioning scheme because of the single-digit major version
component, but that's going away next year regardless, which makes
this the perfect time to raise the topic :)
Thoughts?
