14. Changes in RAUC

14.1. Release 1.0-rc1 (released Oct 12, 2018)

Enhancements

  • Bundle creation
    • Add support for passing Keys/Certificates stored on PKCS#11 tokens (e.g. for using a smart card or HSM). See PKCS#11 Support for details.
    • Print a warning during signing if a certificate in the chain will expire within one month
    • If keyring is given during bundle creation, automatically verify bundle signature and trust chain
  • Configuration (see the reference for the [system], [keyring] and [slot.*.*] sections for details)
    • Add extra-mount-opts argument to slot config to allow passing custom options to mount calls (such as user_xattr or seclabel)
    • Implement support for readonly slots that are part of the slot description but should never be written by RAUC
    • Add option use-bundle-signing-time to use singing time for verification instead of the current time
    • Introduce max-bundle-download-size config setting (by Michael Heimpold)
    • Rename confusing force-install-same flag to ignore-checksum (old remains valid of course) (by Jan Remmet)
    • Add strict parsing of config files as we do for manifests already. This will reject configs with invalid keys, groups, etc. to prevent unintentional behavior
  • Installation
    • Remove strict requirement of using .raucb file extension, although it is still recommended
    • Export RAUC slot type to handlers and hooks (by Rasmus Villemoes)
    • Add *.squashfs to raw slot handling (by Emmanuel Roullit)
    • Add checking of RAUC bundle identifier (squashfs identifier)
    • *.img files can now be installed to ext4, ubifs or vfat slots (by Michael Heimpold)
    • Warn if downloaded bundle could not be deleted
  • Expose system information (variant, compatible, booted slot) over D-Bus (by Jan Remmet)
  • The rauc status command line call now only uses the D-Bus API (when enabled) to obtain status information instead of loading configuration and performing operations itself. This finalizes the clear separations between client and service and also allows calling the command line client wihout requiring any configuration.
  • Add debug log domain rauc-subprocess for printing RAUC subprocess invocations. This can be activated bysetting the environment variable G_MESSAGES_DEBUG=rauc-subprocess. See Debugging RAUC for details.
  • Enhancement of many debug and error messages to be more precise and helpful
  • Let U-Boot boot selection handler remove slot from BOOT_ORDER when marking it bad
  • Implemented obtaining state and primary information for U-Boot boot selection interface (by Timothy Lee)
  • Also show certificate validity times when the certificate chain is displayed
  • Added a simple CGI as an example on how to code against the D-Bus API in RAUC contrib/ folder. (by Bastian Stender)

Bug fixes

  • Bootchooser EFI handler error messages and segfault fixed (by Arnaud Rebillout)
  • Fix preserving of primary errors while printing follow-up errors in update_handlers (by Rasmus Villemoes)
  • Make not finding (all) appropriate target slots a fatal error again
  • Prevent non-installation operations from touching the installation progress information (by Bastian Stender)
  • Call fsync() when writing raw images to assure content is fully written to disk before exiting (by Jim Brennan)
  • Fix casync store initialization for extraction without seeds (by Arnaud Rebillout)
  • Fix slot status path generation for external mounts (by Vyacheslav Yurkov)
  • Do not try to mount already mounted slots when loading slot status information from per-slot file
  • Fix invalid return value in case of failed mark_active()
  • Fix bootname detection for missing root= command line parameter
  • Fix passing intermediate certificates via command line which got broken by a faulty input check (by Marcel Hamer)
  • Preserve original uid/gid during extraction to be independent of the running system. This was only problematic if the name to ID mapping changed with an update. Note that this requires to enable CONFIG_FEATURE_TAR_LONG_OPTIONS when using busybox tar.
  • Block device paths are now opened with O_EXCL to ensure exclusive access
  • Fix handling for file:// URI’s
  • Build-fix workaround for ancient (< 3.4) kernels (by Yann E. MORIN)
  • Various internal error handling fixes (by Ulrich Ölmann, Bastian Stender)
  • Several memory leak fixes

Testing

  • Abort on g_critical() to detect issues early
  • Extended and restructured testing for barebox and u-boot boot selection handling
  • Basic rauc convert (casync) testing
  • Switch to Travis xenial environment
  • Make diffs created by uncrustify fatal to enforce coding style
  • Fix hanging rauc.t in case of failed tests for fixing sharness cleanup function handling
  • Run sharness (rauc.t) tests with verbose output
  • Show make-check log on error

Code

  • Add GError handling to download functions
  • Prepare support for tracing log level
  • Start more detailed annotation of function parameter direction and transfer
  • Simplified return handling as result of cleanup helper rework
  • Treewide introduction of Glib automatic cleanup helpers. Increases minimum required GLib version to 2.45.8 (by Philipp Zabel)
  • Prepare deprecation of RAUC ancient non-bundle ‘network mode’

14.2. Release 0.4 (released Apr 9, 2018)

Enhancements

  • Add barebox-statename key to [system] section of system.conf in order to allow using non-default names for barebox state
  • Support atomic bootloader updates for eMMCs. The newly introduced slot type boot-emmc will tell RAUC to handle bootloader updates on eMMC by using the mmcblkXboot0/-boot1 partitions and the EXT_CSD registers for alternating updates.
  • Support writing *.vfat images to vfat slots
  • Add basic support for streaming bundles using casync tool. Using the casync tool allows streaming bundle updates chunk-wise over http/https/sftp etc. By using the source slot as a seed for the reproducible casync chunking algorithm, the actual chunks to download get reduced to only those that differ from the original system.
    • Add rauc convert command to convert conventional bundles to casync bundle and chunk store
    • Extend update handler to handle .caibx and .caidx suffix image types in bundle
  • Added --detailed argument to rauc status to obtain newly added slot status information
  • Added D-Bus Methods GetSlotStatus to obtain collected status of all slots
  • Extended information stored in slot status files (installed bundle info, installation and activation timestamps and counters)
  • Optionally use a central status file located in a storage location not touched during RAUC updates instead of per-slot files (enabled by setting statusfile key in [system] section of system.conf).
  • Add write-slot command to write images directly to defined slots (for use during development)

Bug fixes

  • Fix documentation out-of-tree builds
  • Fixed packaging for dbus wrapper script rauc-service.sh
  • Some double-free and error handling fixes

Testing

  • Create uncrustify report during Travis run

Code

  • Unified hash table iteration and variable usage
  • Add uncrustify code style configuration checker script to gain consistent coding style. Committed changes revealed by initial run.

Documentation

  • Updated and extended D-Bus interface documentation
  • Added documentation for newly added features (casync, central slot status, etc.)
  • Fixed and extended Yocto (meta-rauc) integration documentation
  • Add link to IRC/Matrix channel
  • Some minor spelling errors fixed

14.3. Release 0.3 (released Feb 1, 2018)

Enhancements

  • Added support for intermediate certificates, improved bundle resigning and certificate information for hooks. This makes it easier to use a multi-level PKI with separate intermediate certificates for development and releases. See Resigning Bundles for details.
  • Added support for image variants, which allow creating a single bundle which supports multiple hardware variants by selecting the matching image from a set contained in the bundle. See Handling Board Variants With a Single Bundle for details.
  • Added support for redundant booting by using EFI boot entries directly. See EFI for details.
  • Added boot information to rauc status
  • Added rauc extract command to extract bundles
  • Support detection of the booted slot by using the UUID= and PARTUUID= kernel options.
  • Improved the status and error output
  • Improved internal error cause propagation

Bug fixes

  • Fixed boot slot detection for root=<symlink> boot parameters (such as root=/dev/disk/by-path/pci-0000:00:17.0-ata-1-part1)
  • Removed redundant image checksum verification during installation.

Testing

  • Improve robustness and test coverage
  • Use gcc-7 for testing

Documentation

  • Added documentation for
    • intermediate certificates
    • re-signing bundles
    • image variants
    • UEFI support
  • Minor fixes and clarifications
