[OpenAFS-announce] OpenAFS release 1.6.12 available

[Stephan Wiesand]

The OpenAFS Release Team is pleased to announce the availability of =
OpenAFS
version 1.6.12 for UNIX/Linux. Source files can be accessed via the web =
at:

  http://www.openafs.org/dl/openafs/1.6.12/

or via AFS at:

   /afs/grand.central.org/software/openafs/1.6.12/
  \\afs\grand.central.org\software\openafs\1.6.12\

There are no binaries yet. Those will be uploaded as they become =
available.

OpenAFS 1.6.12 is the next in the current series of stable releases of =
OpenAFS
for all platforms except Microsoft Windows. Besides other bug fixes and
enhancements, important changes include:

 * A fix to avoid potential database corruption

   With all prior releases of OpenAFS there was a risk of database =
corruption if
   a database server is shut down and then brought up again quickly with =
an
   altered database. This happened if the coordinating server (the "sync =
site")
   hadn't noticed that the peer server is down before the latter is =
started again,
   which could take up to 75 seconds. Details are discussed in [1]. This =
issue is
   fixed in this release by introducing additional checks of the server =
state and
   the validity of the local database.

 * A fix to avoid spurious errors during memory mapped I/O on Linux

   With some kernel versions and under certain conditions, EIO errors =
could
   occur when large chunks of data were written to a memory mapped file =
in AFS.

 * Support for recent Linux kernels up to 4.1

   At the time of writing it seems likely that Linux 4.2 will require =
further
   changes and will thus not be supported by this release.
