Has (macOS-provided) DHCP server; subnet mask and IP range can be configured; * `vmnet-host`: allows the guest to communicate with other guests in host mode. By default has enabled DHCP as `vmnet-shared`, but providing network unique id (uuid) can make `vmnet-host` interfaces isolated from each other and also disables DHCP. * `vmnet-bridged`: bridges the guest with a physical network interface. This backends cannot work on macOS Catalina 10.15 cause we use vmnet.framework API provided only with macOS 11 and newer. Seems that it is not a problem, because QEMU guarantees to work on two most recent versions of macOS which now are Big Sur (11) and Monterey (12). Also, we have one inconvenient restriction: vmnet.framework interfaces can create only privileged user: `$ sudo qemu-system-x86_64 -nic vmnet-shared` Attempt of `vmnet-*` netdev creation being unprivileged user fails with vmnet's 'general failure'. This happens because vmnet.framework requires `com.apple.vm.networking` entitlement which is: "restricted to developers of virtualization software. To request this entitlement, contact your Apple representative." as Apple documentation says: https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_vm_networking One more note: we still have quite useful but not supported 'vmnet.framework' features as creating port forwarding rules, IPv6 NAT prefix specifying and so on. Nevertheless, new backends work fine and tested within `qemu-system-x86-64` on macOS Bir Sur 11.5.2 host with such nic models: * e1000-82545em * virtio-net-pci * vmxnet3 The guests were: * macOS 10.15.7 * Ubuntu Bionic (server cloudimg) This series partially reuses patches by Phillip Tennen: https://patchew.org/QEMU/20210218134947.1860-1-phillip.ennen@gmail.com/ So I included them signed-off line into one of the commit messages and also here. v1 -> v2: Since v1 minor typos were fixed, patches rebased onto latest master, redundant changes removed (small commits squashed) v2 -> v3: - QAPI style fixes - Typos fixes in comments - `#include`'s updated to be in sync with recent master v3 -> v4: - Support vmnet interfaces isolation feature - Support vmnet-host network uuid setting feature - Refactored sources a bit v4 -> v5: - Missed 6.2 boat, now 7.0 candidate - Fix qapi netdev descriptions and styles (@subnetmask -> @subnet-mask) - Support vmnet-shared IPv6 prefix setting feature v5 -> v6 - provide detailed commit messages for commits of many changes - rename properties @dhcpstart and @dhcpend to @start-address and @end-address - improve qapi documentation about isolation features (@isolated, @net-uuid) v6 -> v7: - update MAINTAINERS list v7 -> v8 - QAPI code style fixes v8 -> v9 - Fix building on Linux: add missing qapi `'if': 'CONFIG_VMNET'` statement to Netdev union Vladislav Yaroshchuk (7): net/vmnet: add vmnet dependency and customizable option net/vmnet: add vmnet backends to qapi/net net/vmnet: implement shared mode (vmnet-shared) net/vmnet: implement host mode (vmnet-host) net/vmnet: implement bridged mode (vmnet-bridged) net/vmnet: update qemu-options.hx net/vmnet: update MAINTAINERS list MAINTAINERS | 5 + meson.build | 4 + meson_options.txt | 2 + net/clients.h | 11 ++ net/meson.build | 7 + net/net.c | 10 ++ net/vmnet-bridged.m | 111 ++++++++++++ net/vmnet-common.m | 330 ++++++++++++++++++++++++++++++++++ net/vmnet-host.c | 105 +++++++++++ net/vmnet-shared.c | 92 ++++++++++ net/vmnet_int.h | 48 +++++ qapi/net.json | 132 +++++++++++++- qemu-options.hx | 25 +++ scripts/meson-buildoptions.sh | 3 + 14 files changed, 883 insertions(+), 2 deletions(-) create mode 100644 net/vmnet-bridged.m create mode 100644 net/vmnet-common.m create mode 100644 net/vmnet-host.c create mode 100644 net/vmnet-shared.c create mode 100644 net/vmnet_int.h -- 2.23.0
