User-Visible OpenAFS Changes

OpenAFS 1.9.1

  All platforms

    * Fix initial Rx Connection ID (CID) generation.
      Remove stale initialization and overflow detection logic that resulted
      in connection failures due to all CIDs being set to 0x80000002.
      (14491, 14492, 14496)

    * Fix RPC hangs if a server is restarted while a client is sending
      data (13875 13758 13876).

    * Fix xstat_cm_test/xstat_fs_test -period option bug introduced
      by pthreaded xstats. (14366)

    * Fix remote_is_server field in Rx RPC statistics. Before this fix, the
      rxstat_get_process and rxstat_get_peer programs reported all RPC stats
      as "accessed as a client" (14374).

    * Fix an incorrect server type reported by rxstat_get_process and
      rxstat_get_peer programs (14375).

    * Fix the clock square calculation for stats reported by xstat_fs_test,
      xstat_cm_test, rxstat_get_process, and rxstat_get_peer (14376)

    * Avoid packet resend delays when ICMP socket errors are
      encountered (14424).

    * Report RxRPC packet statistics for version packets, that had previously
      been ignored (14519).

    * Fix various issues detected by static-analyzer tools (13155, 13156,
      13163, 13206, 13333, 14501).

  All server platforms

    * Add support for multiple audit log interfaces and options (13774).

    * Fix a directory handle leak in the convertROtoRWvolume procedure
      when a new transaction cannot be created (14342).

    * Fix out of range memory access when orphaned vnodes are encountered
      during salvages (14385).

    * Add KeyFileExt and rxkey.keytab access rights checks to the
      bosserver and log all access check failures instead of stopping
      on the first failure (14239, 14330).

    * Fix creation of the bosserver audit log file when the bosserver
      is started with the -auditlog option (14381)

    * Fix 'bos salvage -forceDAFS' when the DAFS fileserver is stopped (14382).

    * Add VL_DBBAD ("Database is inconsistent") error code to indicate vlserver
      database inconsistencies, and report VL_DBBAD when unable to remove
      deleted vlentries from the database hash chains (13382, 13383)

    * Fix possible memory leaks when under memory pressure (13156 13313).

    * Fix possible double release of volume locks in vos release
      and vos convertROtoRW (14426).

    * Fix -partition option requires a -server option checks in vos (14005).

    * Take the target read/write volume offline during the conversion
      to a read-only volume by vos convertRWtoRO (14340).

    * Check for volume lock inconsistencies in vldb_check (14307).

    * Document vos restore -readonly option (14348).

    * Consolidate implementation of, and more reliably use, logged warnings
      for single-DES or missing keys (10831).

  All client platforms

    * Avoid panic when failing to allocate a new vnode or
      failing to write a dcache (13701, 13804).

    * Fix double release of afs_xvcb lock (14411).

    * Log process name and PID on disk cache read errors (14416).

    * Add cache-too-full and wait-for-drain cache manager stats (13168).

    * Add afsio readdir and afsio fidreaddir commands to dump
      AFS3 directories (12381).

    * Fix diagnostic messages from "vos partinfo" to correctly refer to
      itself (14489).

  Linux

    * Fix file leak in background thread regression introduced by
      13284 (LINUX: Turn on AFS_NEW_BKG). (13984)

    * Avoid getcwd() and bind-mount call errors by returning
      errors from the d_revalidate callback (14417).

      support (14499, 14500).

    * Support Linux 5.12-RC2 (14548, 14549).

  Solaris

    * Add the OpenAFS provider for the Solaris kstat framework (13170).

  FreeBSD

    * Import the start of a series of locking and stability fixes developed by
      Tim Creech and Andrew Deason that will culminate in a client that
      supports FreeBSD 12.2 (13854, 13856, 13858..13860, 13998..14000, 14162,
