Replace runtime WSL2_TEST_ONLY()/WSL1_TEST_ONLY() skip macros with
TAEF metadata-based test selection. Tests that don't apply to the
current WSL version are now excluded by /select: queries at selection
time rather than skipped at runtime, eliminating hundreds of 'skipped'
results from test output.
Changes:
- Add WSL2_TEST_METHOD, WSL1_TEST_METHOD, WSLC_TEST_METHOD macros
in Common.h that tag tests with WSLVersion metadata property
- Convert ~430 test methods across 26 files to use new macros
- Update run-tests.ps1 to auto-add /select: version filter
- Update CloudTest XML configs with version selection queries
- Remove WSL2_TEST_ONLY() from composite macros in NetworkTests.cpp
- Update test README with new macro documentation

* Fix CVE-2026-26127: bump .NET runtime from 10.0.0 to 10.0.4 (#14421)
Addresses Dependabot alerts #10 and #11. The Microsoft.NETCore.App.Runtime
packages (win-x64 and win-arm64) at version 10.0.0 are vulnerable to a
denial of service via out-of-bounds read when decoding malformed Base64Url
input (CVSS 7.5 High). Bumped to 10.0.4 which includes the fix.

* Notice change from build: 141806547 (#14423)
Co-authored-by: WSL notice <noreply@microsoft.com>
* Ship initrd.img in MSI using build-time generation via powershell script (#14424)
* Ship initrd.img in MSI using build-time generation via tar.exe
Replace the install-time CreateInitrd/RemoveInitrd custom actions with a
build-time step that generates initrd.img using the Windows built-in
tar.exe (libarchive/bsdtar) and ships it directly in the MSI.
The install-time approach had a race condition: wsl.exe could launch
before the CreateInitrd custom action completed, causing
ERROR_FILE_NOT_FOUND for initrd.img.
Changes:
- Add CMake custom command to generate initrd.img via tar.exe --format=newc
- Add initrd.img as a regular file in the MSI tools component
- Remove CreateInitrd/RemoveInitrd custom actions from WiX, DllMain,
and wslinstall.def
- Remove CreateCpioInitrd helper and its tests (no longer needed)
- Update pipeline build targets to build initramfs instead of init
* pr feedback
* more pr feedback
* switch to using a powershell script instead of tar.exe
* powershell script feedback
* hopefully final pr feedback

* virtio networking: add support for ipv6 (#14350)
* VirtioProxy: Add IPv6 address, gateway, and route support
- Add PreferredIpv6Address field and GetBestGatewayV6* methods to NetworkSettings
- Extend GetHostEndpointSettings() to discover IPv6 unicast address and gateway
- Add UpdateIpv6Address() using ModifyGuestEndpointSettingRequest<IPAddress>
- Push IPv6 default route to guest via UpdateDefaultRoute(AF_INET6)
- Remove AF_INET6 early return in ModifyOpenPorts, use INETADDR_PORT()
- Add EndpointRoute::DefaultRoute() static factory
- Pass client_ip_ipv6 in devicehost options (not yet parsed by devicehost)
- Remove gateway_ip from devicehost options (only needed for DHCP)
- Include IPv6 DNS servers in non-tunneling DNS settings
- Add ConfigurationV6 and DnsResolutionAAAA tests

* Add iptables to list of apps to install in WSL (#14459)
There were instructions already on how to install tcpdump in WSL, but
iptables are also needed for the log collection to be complete, so this
PR adds instructions on how to also install iptables.

* Moves all Ubuntu distros to the tar-based format (#14463)
* Move all supported Ubuntu images to the new format
We backported the build pipeline so all current LTSes come out in the new tar-based format
* Remove the appx based distros
All WSL users can run tar-based distros by now, right?
There is no benefit in maintaining both formats.
* Enable DNS tunneling for VirtioProxy networking mode (#14461)
- Allow VirtioProxy to keep EnableDnsTunneling=true in config, but clear
socket-specific options (BestEffortDnsParsing, DnsTunnelingIpAddress)
- Suppress dedicated DNS tunneling hvsocket for VirtioProxy; tunneling
is handled through the VirtioNetworking device host instead
- Set DnsTunneling flag on VirtioNetworkingFlags so the device host
knows to tunnel DNS
- Expand SWIOTLB kernel cmdline to cover VirtioFs and VirtioProxy
- Bump DeviceHost package to 1.1.39-0
- Add VirtioProxy DNS test coverage for tunneling on/off
- Skip GuestPortIsReleasedV6 on Windows 10

* Refactor: trim unnecessary DLL deps from COMMON_LINK_LIBRARIES
- Split MSI/Wintrust install functions from wslutil.cpp into install.cpp
- Remove MI.lib, wsldeps.lib, msi.lib, Wintrust.lib, computecore.lib,
computenetwork.lib, Iphlpapi.lib from COMMON_LINK_LIBRARIES
- Add per-target MSI_LINK_LIBRARIES, HCS_LINK_LIBRARIES, SERVICE_LINK_LIBRARIES
- Delay-load msi.dll and WINTRUST.dll for wsl.exe and wslg.exe
- Result: wslhost, wslrelay, wslcsdk, testplugin lose msi/wintrust startup imports;
wsl.exe and wslg.exe defer msi/wintrust loading until actually needed;
wslservice is the only target that imports computecore/computenetwork/Iphlpapi
* minor fixes to install.cpp that were caught during PR
* move to wsl::windows::common::install namespace
