User-Visible OpenAFS Changes

OpenAFS 1.6.11 (in progress)

  All platforms

    * Allow aklog to succeed creating native K5 tokens even when mapping
      the K5 principal to a K4 one fails (11538)

    * Build fixes (11435 11636)

  All client platforms

    * Avoid a potential kernel panic due to connection reference overcounts
      (11645) (RT #131885)

    * Avoid potential corruption of files written using memory mapped I/O
      when the file is larger than the cache (11656) (RT #131976)

  Linux clients

    * Support kernels at least up to 3.19 (11549 11550 11569 11570 11595
      11658..11662 11694)

      Note: By default this excludes kernels 3.17 to 3.17.2, which will leak
            an inode reference when an error occurs in d_splice_alias(). The
            module will build and work, but leak kernel memory, leading to
	    performance degradation and eventually system failure due to
	    memory exhaustion. Since it's impossible to detect this condition
	    automatically, the switch --enable-linux-d_splice_alias-extra-iput
	    must be passed to configure when building the module for those
	    kernels. The same would be necessary for any kernel with backports
	    of commit 908790fa3b779d37365e6b28e3aa0f6e833020c3 or commit
	    95ad5c291313b66a98a44dc92b57e0b37c1dd589 but not the fix in commit
	    51486b900ee92856b977eacfc5bfbe6565028070 in the linux-stable repo
	    (git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git) or
	    the corresponding changes on other branches.

    * Fixed a regression introduced in OpenAFS release 1.6.10 which could
      make the spurious "getcwd: cannot access parent directories" problem
      return (11558 11568) (RT #131780)

    * Avoid leaking memory when scanning a corrupt directory (11707)

  OS X clients

    * Support OS X 10.10 "Yosemite" (11571 11572 11611) (RT #131946)

  Solaris clients

    * Avoid reading random data rather than correct cache content when using
      ZFS as the cache file system on Solaris >= 11, and fix potential similar
      problems on other platforms (11713 11714)

  FreeBSD

    * Build fix for releases >= 11.0 (11610)

  OpenBSD

    * Support release 5.4 (11700)
