[PATCH] hyperv: add support for secure boot configuration
by Jonathon Jongsma 18 Feb '26

18 Feb '26

When getting the xml description of a guest, check if secure boot is enabled and set firmware features accordingly. Also support firmware autoselection and honor the secure boot setting when defining new vms from xml.

[PATCH v2] qemu: Store tapfd path in domstatus XML
by Wesley Hershberger 16 Feb '26

16 Feb '26

Introduce a read-only `tapfd` element for direct interfaces (macvtap), which contains the path to the backing tapfd for that interface (e.g. `/dev/tapXX`). The element is only included when the domain is being formatted for internal consumption (VIR_DOMAIN_DEF_FORMAT_STATUS) and is not accepted in user-provided XML (!VIR_DOMAIN_DEF_PARSE_INACTIVE). This is used by the AppArmor security driver when re-generating profiles. Partial-Resolves: #692 Bug-Ubuntu: https://bugs.launchpad.net/bugs/2126574 Signed-off-by: Wesley Hershberger <wesley.hershberger(a)canonical.com> --- This submission is a partial revision of a previous series with a fix for the macvtap component of gitlab#692 [1][2]. I haven't had bandwidth to resolve the blockcommit component since the complexity there is somewhat higher (and is also lower priority for us). I kept the separate `tapfd` element rather than reusing the existing `backend` element (virDomainNetBackend.tap) to avoid making a user-visible change [3]. I'd be happy to use the existing field instead if you think that would make more sense. I opted not to introduce/modify a security driver API for FD+path as the patch here is sufficient to resolve the bug, but would be willing to do so if that would make this change more palatable. I've opened a MR to libvirt-tck with test cases that demonstrate the bugs that this fixes [4]. apparmor/110-macvtap.t passes with this patch applied.

[PATCH] scripts: avoid matching 'char **' as string for systemtap

From: Daniel P. Berrangé <berrange(a)redhat.com> When a probe argument is declared "char *" we reference the userspace string value using 'user_string(...)' for systemtap.

[PATCH v4 0/5] nwfilter: add nwfilter nftables driver
by Dion Bosschieter 16 Feb '26

16 Feb '26

This series aims to implement nftables as a backend driver for the nwfilter feature. The idea is that eventually it will replace the ebiptables driver and provide an easy way for users to switch from one driver to another. The first 2 patches are moving of functions and renames, meant to decouple nwfilter from the currently only existing ebiptables driver. The 3rd patch introduces the new nwfilter driver. After which nwfilter allows users to choose it in the 4th patch. The last patch introduces unit testing of the new nftables driver. - Implemented very basic nwfilter.conf reading and choosing a nwfilter driver based on the name of the drivers (nftables/ebiptables). Defaults to the nftables driver, based on the firewall_backend_priority meson option, following the bridge driver logic. - Resolves issue https://gitlab.com/libvirt/libvirt/-/issues/603 benchmarks showed that the amount of iifname jumps for each interface with is the cause for this. Switched the nftables driver towards a vmap (verdict map) so we can have 1 rule that jumps to the correct root input/output chain per interface. Which improves throughput as when the number of interface check and jump rules increases the throughput decreases. The issue describes the interface matching works using the interface name and the majority of the effort is the strncpy, this commit also switches nftables to an interface_index compare instead. However, just using the interface_index is not enough, the amount of oif and iif jump rules causes quite a performance issue, the vmap instead solves this. - Split rules into separate tables: "libvirt-nwfilter-ethernet" and "libvirt-nwfilter-other" to preserve existing firewall behavior. - Reworked chain logic for clarity with root -input/-output chains per interface. input in the VM interface is filtered in the -input chain(s), output out of the VM inteface is filtered in the -output chain(s). - Stuck with prerouting and postrouting as hooks for input / output on the -ethernet and -other table. This makes it easier to merge the tables in the future. Saving management of two tables and decreasing the amount of tables a packet sees. Currently ebtables filtering happens via PREROUTING and POSTROUTING hooks, while ip/ip6tables filtering happens in the output/forward hooks. - Stuck with 2 tables for compatibility reasons with eb iptables, unifying into 1 table will break users firewall definitions, which depend on being able to do accepts on ethernet rules (which currently get defined via ebtables) and additional filtering via the ip rules (which currently get defined via ip(6)tables). The nwfilter_nftables_driver keeps splitting the ethernet and non ethernet (other) rules in seperate tables "libvirt-nwfilter-ethernet" and "libvirt-nwfilter-other". - Rewrote chain logic, so it is easier to understand, input in the VM interface is filtered in the -input chain(s), output out of the VM inteface is filtered in the -output chain(s). -ethernet and -other table follow the same style and hook in the same way. - Simplified conntrack handling: rules with accept+conntrack are duplicated to the opposite chain for symmetric behavior, to support the existing ebiptables logic. - Firewall updates continue use tmp names for atomic replacement. Unsupported nwfilter features (for now): - STP filtering - Gratuitous ARP filtering - IPSets (potential future support via nft sets) - Reject due to filtering in pre/postrouting, using drop instead of reject, copying logic from existing ebiptables ebtables actions Future improvements: - Use `nft -f` for atomic rule application. - Optional single-table mode via nwfilter.conf. - Optimize boot phase with chain hash comparison. --- Changes in v4: - Fix rarp nft commands "arp saddr ether" "arp daddr ether" - Filter chain creation, don't create unnecessary chains - Apply danpb seperate argument suggestion - Fix table not existing errors in drop all rules - Fix table not existing errors in apply basic rules Changes in v3: - Renamed -other to -inet - Renamed - to _ in table names - Updated rule / chain sorting on ethernet table to to copy ebtables logic - Fix possible broken revert path - Fix remove rules not working in some cases, EBUSY - Shared functions camel case commit - Rename config option - Add extra config params, enable_trace, enable_counters This required passing the config struct to the ebip/nft nwfilter drivers - Add extra augeaus files Changes in v2: - Rename {ebip,nf}tables specific test files in 1 directory instead of seperating them in different directories. - Added default nwfilter.conf file in git, documented including augeas files - Replaced hardcoding of default driver based on existing firewall_backend_priority meson option. - Added nwfilter_driver_conf.{h,c} for configuration handling, to match the common pattern used in other drivers. Dion Bosschieter (5): nwfilter: rename generic names to virNWFilter* and CamelCase nwfilter: move shared nwfilter driver functions into nwfilter_tech_driver.c nwfilter: add nwfilter nftables driver

[PATCH 0/5] conf: Add firmwareFeatures element for domaincaps
by Andrea Bolognani 13 Feb '26

13 Feb '26

This is primarily intended to as a companion to my series that makes it possible to use Secure Boot on aarch64[1], but I'm posting it separately because it's independently useful and could be pushed before it. Depending on which one of the two series is merged first, some minor conflict resolution will need to be applied to the other.
