User-Visible OpenAFS Changes


OpenAFS 1.8.8 (in progress)

  All platforms

    * Improved documentation, diagnostics and error messages (14311 14326
      14331 14367 14399 14419 14420 14427 14434 14436 14437 14438 14439
      14440 14502 14516 14518 14546)

    * Build fixes, mostly for recent compilers (14217 14298 14299)

    * Avoid some potential performance losses in the wire protocol (14503
      14514)

    * Avoid client connections hanging forever when the server is
      restarted while they're active (14504 14505 14506 14507)

  All server platforms

    * Avoid Rx calls getting stuck on the incoming call queue for busy
      servers (14394)

    * Avoid a possible salvageserver deadlock (14283)

    * Fixed salvageserver's parsing of the "-parallel all<number>" argument
      (14285)

    * Avoid potential salvager crashes (14515 14614)

    * Avoid erratic vlserver behaviour due to overflowing the maximum
      VLDB size of 2 GB. Log a message and return an error instead (14288)

    * Fixed a ptserver issue where 'pts mem -expandgroups' failed when
      supergroups were enabled (14345)

    * Take read-only volumes offline while being converted to read-write
      ones with "vos convertROtoRW", preventing them from ending up in an
      inconsistent state when accessed during the conversion (14433)

    * Avoid inconsistent volume states due to interrupted rename operations
      and other potential issues (14449 14450)

    * Add new variants to asetkey's "delete" command to allow deleting
      non-des keys (14293)

    * Improved ubik performance and robustness (14141 14142 14365)

    * Fixed building the vol-bless utility, which is now also built by
      default but still not installed and distributed (14601)

    * Fixed parsing of "-cores none" when bosserver is started this way
      (14589)

  All client platforms

    * Avoid crashes or panics when potentially recoverable errors
      during cache I/O are encountered (14286)

    * Avoid flooding servers with NAT pings, which could happen under
      certain circumstances (14364)

    * Avoid possible panics during client startup or shutdown (14393 14441)

    * Fixed several potential problems in "aklog -keytab" (14478 14479
      14480 14481 14482)

    * Performance improvements (14391)

    * Avoid unexpected "cold" shutdowns upon umount /afs on platforms
      which should perform a "warm" shutdown by default (14610)

    * Avoid memory leaks during shutdown (14615 14616)

    * Fixed building the afscp utility, which is still not built by default
      though (14627)

  Linux clients

    * Support mainline kernels up to and including 5.12 (14267 14268 14269
      14315 14563 14564 14565)

    * Avoid failures of cache I/O operations in the context of tasks
      restricted by security mechanisms like AppArmor (14082 14099)

    * Avoid a crash while loading the kernel module when reading from
      /proc/fs/openafs/CellServDB before afsd has started (14284)

    * Avoid more possible causes of getcwd() failures (14451)

    * Restore the -setpag functionality in some older utilities like klog
      (14327 14328)

  macOS

    * Added support for release 11.0 "Big Sur" (14597 14598 14605 14600)

  FreeBSD

    * Support releases 11.2, 12.1, 12.2 (14520 14537 14590)

    * Add a wide range of FBSD specific fixes and improvements (14521..36)
