User-Visible OpenAFS Changes

OpenAFS 1.8.15pre1

  All platforms

    * The generically named lock.h header file has been renamed to
      afs/afs_lock.h to avoid conflicts with other software.  For
      backward compatibility, a wrapper lock.h is still provided, ensuring
      that older software built against OpenAFS will continue to compile. Any
      users of lock.h should update to using afs/afs_lock.h as soon as
      possible; the lock.h wrapper will be removed in the future.
      (16605, 16610, 16611)

  All server platforms

    * A fileserver bug has been fixed where uninitialized data from the
      stack could be sent over the network when handling certain
      protection-related RPCs. This change prevents a potential information
      leak. (16207)

    * A potential race condition has been fixed in the fileserver that was
      only triggerable by the obsolete RXAFS_GetVolumeInfo RPC. (16206)

    * A fileserver bug has been fixed where the SRXAFS_GetStatistics64 RPC
      could send 4 bytes of uninitialized memory over the network. This change
      prevents a potential information leak from the fileserver. (16205)

  All UNIX clients

    * A long-standing bug has been fixed in the afs_create() operation where
      callback expiration was processed incorrectly.  This could lead
      to processes reading stale data for newly-created files under certain
      conditions. (16612)

    * A memory leak during error conditions in the PGetVolumeStatus pioctl
      has been fixed. (16262)

    * A race condition has been fixed where the client asserts during startup
      when the client was started with `afsd -fakestat` or `afsd -fakestat-all`
      and a user attempts to set a token early in the startup. (16653)

  Linux client

    * Support for Linux kernel 6.17 has been added. (16603, 16604)

    * A potential race condition on Linux clients has been fixed that could
      cause a spurious SIGBUS error when reading memory-mapped files from AFS.
      This bug was introduced in OpenAFS 1.6.0. (16616)

  MacOS client

    * A bug has been fixed where the privhelper component of the prefpane was
      not honoring the configured compiler flags.  This caused the prefpane
      operations to not work on x86 for universal packages built on arm. (16662)

  AIX

    * Build support for AIX has been improved. (16125, 16126, 16127, 16128,
      16129, 16633, 16634)

    * Installation instructions for AIX have been reinstated. (16635)
