Version 0.9.3

Fix for the fix Released: 2022-08-23

  • Work around a glib fix that changed behavior of the log API where now calling g_log_set_writer_func results in an hard error, which broke the test suite since aforementioned function was indeed called more than once. Nothing a level of indirection couldn't fix.

  • CI: disable Debian based ci for now. Another glib fix broke the Debian and Arch based docker container. Fedora has patched glib to bake the fix out again so it is fine.

Version 0.9.2

Please get along Released: 2022-01-27

  • This release is compatible with umockdev >= 0.16.3; there was a change in umockdev that made our test fail with it, since both our test and umockev were trying to create the same directorires. bolt now allows for the dir to already exist.

  • The license for 90-bolt.rules has changed from GPL-2.1+, which does not exist and was probably was confused with LGPL-2.1+, to GPL 2.0+.

  • Documentation has been updated and spelling mistakes fixed.

  • Various improvements for continuous integration.

  • The minimum required version of meson has been bumped to 0.46.0.

Version 0.9.1

Unstable icy waters Released: 2020-11-30

  • Bug fixes for integrated thunderbolt controllers: On Ice Lake, the Thunderbolt 3 i/o subsystem is fully integrated into the die. As a side effect it does not have a DROM, which means the host udev device does not have the device and vendor name and id attributes. Additionally the unique_id of said host controller changes with every boot, which breaks one of the fundamental assumptions in boltd. Therefore a number of bug fixes were necessary to properly support this new architecture:

    • Don't store domains where uuids change across reboots [!220]
    • Fixes for the journal and the domain's acl-log [!221]
    • Version the store and use that to clean up stale domains once [!226, !231]
    • Host identification for embedded thunderbolt controllers [!233]

  • Various other small bug fixes and memory leak fixes.

      • newly enrolled devices get added to all bootacls of all domains if the policy is BOLT_POLICY_AUTO
      • removed devices get deleted from all bootacls of all domains
      • boltacl domain command will show the bootacl slots and their content
