V3: https://lists.libvirt.org/archives/list/devel@xxxxxxxxxxxxxxxxx/thread/HOCDIMI3SHS6UFFZJUAXUE6VLXE6SVHV/ V2: https://lists.libvirt.org/archives/list/devel@xxxxxxxxxxxxxxxxx/thread/5RTZ6PC3N3CO6X353QUHLVOL43SWQ4JD/ 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). Changes from V3: * Fixed a bug (newly added in V3) that resulted in the firewall name attribute not being added to the XML. * renamed the table to "libvirt_network" (new patch 28) * renamed the chains to be more descriptive, and lower case rather than all caps. (new patch 29) * eliminated all the guest->host and host->guest rules since they are redundant in nftables. (new patch 30) Laine Stump (30): util/network: move viriptables.[ch] from util to network directory network: move all functions manipulating iptables rules into network_iptables.c network: make all iptables functions used only in network_iptables.c static util: #define the names used for private packet filter chains util: change name of virFirewallRule to virFirewallCmd util: rename virNetFilterAction to iptablesAction, and add VIR_ENUM_DECL/IMPL util: check for 0 args when applying iptables rule util: add -w/--concurrent when applying a FirewallCmd rather than when building it util: determine ignoreErrors value when creating virFirewallCmd, not when applying util/network: new virFirewallBackend enum network: add (empty) network.conf file to distribution files network: support setting firewallBackend from network.conf network: framework to call backend-specific function to init private filter chains util: new functions to support adding individual firewall rollback commands util: implement rollback rule autocreation for iptables commands network: turn on auto-rollback for the rules added for virtual networks util: add name attribute to virFirewall util: new function virFirewallNewFromRollback() util: new functions virFirewallParseXML() and virFirewallFormat() conf: add a virFirewall object to virNetworkObj network: use previously saved list of firewall removal commands network: save network status when firewall rules are reloaded meson: stop looking for iptables/ip6tables/ebtables at build time network: add an nftables backend for network driver's firewall construction tests: test cases for nftables backend network: prefer the nftables backend over iptables spec: require either iptables or nftables if network driver is installed network: name the nftables table "libvirt_network" rather than "libvirt" network: rename chains used by network driver nftables backend network: eliminate pointless host input/output rules from nftables backend libvirt.spec.in | 7 +- meson.build | 10 +- meson_options.txt | 1 + po/POTFILES | 3 +- src/conf/virnetworkobj.c | 41 + src/conf/virnetworkobj.h | 8 + src/libvirt_private.syms | 58 +- src/network/bridge_driver.c | 39 +- src/network/bridge_driver_conf.c | 64 + src/network/bridge_driver_conf.h | 3 + src/network/bridge_driver_linux.c | 630 +------ src/network/bridge_driver_nop.c | 6 +- src/network/bridge_driver_platform.h | 6 +- src/network/libvirtd_network.aug | 39 + src/network/meson.build | 36 + src/network/network.conf.in | 28 + src/network/network_iptables.c | 1677 +++++++++++++++++ src/network/network_iptables.h | 30 + src/network/network_nftables.c | 968 ++++++++++ src/network/network_nftables.h | 28 + src/network/test_libvirtd_network.aug.in | 5 + src/nwfilter/nwfilter_ebiptables_driver.c | 1004 +++++----- src/util/meson.build | 1 -
