The documentation for this release is available at https://docs.system-transparency.org/st-1.2.0/ A release tar file is published at https://dist.system-transparency.org/st/st-1.2.0.tar.gz https://dist.system-transparency.org/st/st-1.2.0.tar.gz.sig The release keys used for both the release tar file and the corresponding git tags are published at https://www.system-transparency.org/keys This collection release corresponds to the manifest file https://git.glasklar.is/system-transparency/core/system-transparency/-/blob… Project homepage and contact information can be found at https://www.system-transparency.org/ Cheers, The System Transparency team NEWS for st-1.2.0 This is an update to the st-1.1.0 collection release, with a few new features requested by users. It is intended to be backwards compatible with the st-1.0.0 and st-1.1.0 collections except for a new build-time requirement on go-1.22 or later. The code components of st-1.2.0 are stboot v0.5.2, stmgr v0.5.2, and stprov v0.4.2 (also listed, with corresponding commit hashes, in the manifest file). Corresponding documentation is included in the collection, and it is also published at https://docs.system-transparency.org/st-1.2.0/. Bug fixes: * stprov: Don't add any extra dot when using default hostname (neither -h or -H specified on the command line). * stmgr: Properly assign the issuer and subject in generated X.509 certificates. Features: * stboot: Add support for encrypted OS packages. * stprov: For network autoselect (-A), prefer the fastest network interface. * stboot, stprov: Improvements to logging. * stboot, stprov: Display and populate the new (and optional) "description" field in the host configuration. * stmgr: The uki subcommand can now produce both .uki and .iso in the same run.

It is intended to be backwards compatible with the st-1.0.0 collection. Using a relative os_pkg_url for OS packages served (one of the new features) requires an stboot upgrade, or else the boot will fail. Bug fixes: * stboot: When stboot is started as the init process (pid 1), it now loads kernel modules *before* mounting the efivarfs. Previously, accessing EFI variables required that the efivarfs driver was compiled statically into the kernel, rather than as a module.

Features: * stboot: If a provisioning OS package is included in the stboot image, the operator can force stboot into provisioning mode by pressing Ctrl-C to interrupt normal boot, and stboot can similarly enter provisioning mode if normal boot fails for any other reason. See https://docs.system-transparency.org/st-1.1.0/docs/reference/stboot-system/… * stboot, stmgr: the OS package archive URL (os_pkg_url) can now be relative to the OS package pointer.

The most notable feature is the ability to enter provisioning mode even if a host configuration has already been provisioned on the system. Bug fixes: * When running stboot as the init process, load kernel modules before trying to mount /sys/firmware/efi/efivars. This ensures EFI variables will work when the efivarfs driver is provided as a loadable kernel module (rather than being built into the kernel). For users that use u-root as the init process: be aware that the same issue which has now been fixed in stboot still remains open in u-root, see https://github.com/u-root/u-root/issues/2993. * Properly wait for the selected network interfaces to reach state UP before considering the network to be configured successfully. This ensures stboot will not spend any of its retries due to interfaces that are not up yet. New features and improvements: * If a provisioning OS package is included in the stboot image, it is now possible to enter provisioning mode if the provisioned host configuration is invalid or if the user presses Ctrl-C. See docs/stboot-system.md for details and security implications. * The OS package descriptor now supports "os_pkg_url" to be relative to the descriptor's (absolute) base URI. Refer to the OS package specification for the exact resolution rules. This release has been tested to work with: * Artifacts produced by stmgr v0.4.0 (pre-release version). https://git.glasklar.is/system-transparency/core/stmgr/-/tree/v0.4.0 * Systems provisioned with stprov v0.3.8 (pre-release version) https://git.glasklar.is/system-transparency/core/stprov/-/tree/v0.3.8 This release implements the specifications at https://git.glasklar.is/system-transparency/project/docs/-/tree/v0.3.0/cont…
