User-Visible OpenAFS Changes

OpenAFS 1.8.1

  All Platforms

    * Improve the usability and consistency of the public API: install missing
      headers, and add additional symbols to the export list for shared libraries.

    * Improved Rx abort generation: use the proper serial number for an existing
      connection if possible, and 0 otherwise (to improve debugging).

    * Assorted minor fixes in response to static analysis of the codebase.

    * Fix memory-safety error in XDR decoding of enumerated types.

  All Server Platforms

    * Fix reference counting error that could cause an assertion failure
      in some workloads.

    * vldb_check -fix will no longer corrupt the vldb when multiple MH blocks are present.

    * Assorted cleanups and efficiency improvements in the ubik implementation.

    * Return a valid InlineBulkStatus response in error cases.

    * The fileserver now rejects invalid partition names when attaching partitions.

  All Client Platforms

    * Fix volume callbacks (e.g., when running 'vos release').

    * Treat failure to obtain a DSlot as a hard error for that cache partition,
      avoiding a flood of "disk cache read error in CacheItems" log messages,
      and reducing the chance of subsequent panic.

    * Improve error messages for invalid values with -volume-ttl.

    * Remove useless error message:
      "find_preferred_connection: no connection and !create".

    * Avoid passing NULL to a kernel memory deallocator, which is not guaranteed
      to be safe on all systems.

  Linux

    * Add support for 64-bit ARM clients ("arm64").

    * Fix panic when cache bypass is enabled.

    * Improve cache manager behavior when unable to open cache files.

    * Improvements to the RPM packaging.

    * Detect out-of-memory when using kernel pages for writing.

  Solaris

    * Fix various issues in the build process for recent Solaris versions.

  MacOS

    * Fix clients on OS X 10.13.

  FreeBSD / NetBSD / OpenBSD

    * Fix panic triggered during periodic cleanup operations and shutdown.
