User-Visible OpenAFS Changes
OpenAFS 1.8 (in progress)
All Platforms
* Substantial code quality improvements, largely spotted by Coverity and
clang's static analysis.
- Add new library for platform independent functions (opr).
- Remove arbitrary path name length limits.
- Convert to Heimdal's roken library for reliability.
- Avoid garbage in allocated buffers (calloc).
- Modernize signal handling in pthreaded server processes (softsig).
- Improve code comments and additional Doxygen style comments.
- Reduce compiler warnings, dead code, unused variables, and
undefined behavior.
- Fix bugs found by static code analyzer (clang-analyzer).
- Improved unit test coverage.
- Make VLDB flag definitions consistent.
- Improve use of run-time assertions and add static assertions.
- Add compiler attributes to assist static analyzers.
- Clean up include headers in the entire tree.
- Improve command-line handling library (libcmd).
- Replace hash functions with Jenkin's hash function for faster
and more evenly distributed lookups.
- Provide a red-black tree data structure to enable algorithmic speedups.
- Convert backup and salvage servers to the common logging API (libutil).
- Improve volume id data type consistency (VolumeId).
- Import APIs for kerberos-style profile configuration support.
- Add new APIs to support UserList identities.
- Add new APIs to support tabular output from command-line utilities.
* Improved support for non-DES encryption types:
- Convert to Heimdal's hcrypto library to support RFC 3961.
- Add extended key file format replacing rxkad.keytab, and
new key management APIs.
- Add support for extended key types to asetkey.
- Add akeyconvert to assist in upgrading to OpenAFS 1.8.x by converting an
existing rxkad.keytab file to an extended key file.
- Do not install the kaserver and related utilities by default to
discourage the use of these DES-dependent components.
- Remove obsolete klogin and klogin.krb programs.
- Add new token APIs to support new rx security classes.
* Migrate from LWP to POSIX threads (pthreads):
- Convert the ptserver and vlserver from LWP to pthreads.
- Remove LWP version of the file server binary.
- Convert afsd, aklog, asetkey, klog.krb5, pts, udebug, and vos, from LWP
to pthreads.
* Improvements to Rx:
- Restructure the Rx API to privatize the implementation.
- Convert rx events to a red-black tree data structure to improve
performance.
- Convert from mutexes to atomic operations for counters to reduce lock
contention.
- Provide per-opcode Rx statistics.
- Add an rx_opaque data type to support non-DES encryption types
and general code cleanup.
* Libraries (both internal and installed) are built using libtool, including
libuafs. The resulting shared libraries for libafsrpc and libafsauthent
should be more usable than previously.
* Improvements to the build system:
- Convert to libtool to build shared libraries.
- Clean up and improve the build system.
- Support out of tree builds.
- Add a makefile target to generate Doxygen source code documentation.
- Link the Java API for OpenAFS with libuafs.a and remove the
libjuafs.a library.
- Always build the rxperf tool.
* Improvements to documentation:
- Document the new KeyFileExt file.
- Reorganized the README files.
- Improvements and fixes to documentation generation.
- Add experimental epub and mobi support
- Remove obsolete LWP information from the file server documentation.
- Update and reorganize the Quick Start Guide.
- Update the Admin Guide.
- Remove AIX, HP-UX, and IRIX information from the Quick Start Guide.
- Document the vldb and prdb (ubik) file formats.
- Corrections and clarifications to man pages.
* Improvements for troublshooting, debugging, and testing:
- Log more details on volume-server-to-fileserver communication errors
when possible.
- Set thread names in pthreaded servers on platforms which support
thread names.
- Add dynroot lock tracking to cmdebug
- Fix tracking of an fstrace call site in the cache manager background
process.
- Add the afsload tool to simulate multiple cache managers for file server
load testing.
- Add run-time checks for refcount imbalances in the cache manager.
* Developer tool improvements:
- Improvements and fixes for rxgen (used to generate Rx RPC bindings).
- Add tool for man page verification of command options.
- Add tool to find Unix cache manager lock identification numbers.
- Add an option for pretty build output.
* Add a new protection error code (PRNAMETOOLONG) instead of silently
truncating names which exceed the maximum name length (PR_MAXNAMELEN).
* Add an implementation limit (50000) on the number of names/ids which can
be transmitted by unauthenticated clients to the ptserver, avoiding
excessive resource consumption from unauthenticated requests.
* Add the -config option to vos, pts, and aklog to specify the path to the
cell configuration files.
* Add more details in vos release -verbose output.
* Add the cacheout -encrypt option to encrypt communication between the
cacheout client and the fileserver.
* Add the command line options to the afsio program to enable encryption of
traffic between afsio and the fileserver (-clear, -crypt).
* Add the vos release -force-reclone option to force recloning the volume to
be released without forcing a full volume dump being transmitted to all
remote sites.
* Fix vos to avoid writing loopback addresses into the VLDB in
certain cases.
* Print bos and pts error messages to standard error instead of
standard out.
* Improve formatting of the -help output of all commands.
* Change -n to -dryrun in all backup subcommands.
* Change the backup deletedump -port command line option to -portoffset.
* Add user and build host in the version string returned by
rxdebug -version.
All Server Platforms
* Ubik servers using pthreads are now available and are used by default
* Remove periodic background fsync by the fileserver (ihandle fsync thread).
* Fix potential file handle leak in the file server ihandle caching layer.
* Disable the so-called "hot threads" feature in the file server. The hot
threads feature was intended as an optimization for dispatching incoming
calls to the current listener thread, but has been reported to incur a
performance penalty on modern multi-core systems.
* Do not permit creation of users with id of ANONYMOUSID.
* Add the ptserver -restrict_anonymous option to inhibit exposure of user
names from the ptserver.
* Do not truncate server log files by default when server processes
are started. The -transarc-logs option provides backward compatibility
with IBM AFS log handling on server startup. Log messages may be lost
in back-to- back restarts when a server is running in this mode.
* Reopen server logs on SIGUSR1. This may be used by third-party log
rotation tools, such as logrotate, to reopen the log file handles after
log files have been renamed.
* Fix various bugs when logging with -mrafslogs enabled.
* Dynamically reload the kerberos realm to AFS cell mapping (krb.conf) and
exclusions for mapping kerberos principals to AFS identities (krb.excl)
configuration when the CellServDB cell configuration file is touched.
Previously, a restart of the file server was required after updating the
kerberos mapping configuration files.
* Add a command line option (-restricted_query) to the vlserver and
volserver to restrict information queries about volumes to a specific
group of users.
* Add a command line option to the server programs to specify an alternate
fully qualified log file name (-logfile).
* Add a command line option (-config) to the server programs to specify
an alternate path to the server configuration.
* Add a command line option to the ptserver and vlserver to specify an
alternate path to the database data files.
* Add a command line option to the volume server to enable encryption of
volume-server-to-volume-server-traffic (-s2scrypt).
* Increase the maximum number of LWP threads allowed for the ptserver and
vlserver from 16 to 64 (-lwp).
* Remove an unused file server command line option (-k).
* Fix an incorrect assertion in Demand Attach File Server which could cause
the file server process to abort in certain rare conditions.
* Deprecate the -bitmap-later configure option for non-Demand-Attach File
Servers (DAFS).
* Add -vhashsize support to non-Demand-Attach File Servers (DAFS).
* Add support for subnet ranges in the NetInfo and NetRestrict
configuration files.
* Add the GetXStats RPC to the audit log.
* Fix directory creation by bosserver when built for non-Transarc paths.
* Fix incomplete list of server addresses retreived by vos listaddr when the
vldb contains unreferenced multi-homed server entries.
* Remove obsolete bos blockscanner and unblockscanner commands that
were only needed for the removed MR-AFS functionality.
* Remove obsolete bos salvage options that were only used by the
removed MR-AFS functionality..
* Remove calls to the deprecated sbrk() function.
* Add an experimental feature to database servers to support ubik reads
while write transactions are in progress, enabled at build time with the
--enable-ubik-read-while-write configure option. This feature is not
considered ready for production usage at this time.
All Client Platforms
* Add support for relative ACL changes with fs setacl. If a single plus (+)
or minus (-) character is appended to the rights' letters argument, the
new rights are computed relatively to the existing ones.
* Remove afsd -settime and afsd -nosettime support.
* Add the afsd -inumcalc option to specify the method used to calculate
inode numbers presented by AFS.
* Return EIO on internal errors instead of the misleading ENOENT.
* Log ICMP errors received, if any, for unreachable servers.
* Improve performance of clients with multiple PAGs for different cells.
* Fix race condition between changing and using user tokens among cache
manager threads.
* Fix fs sysname for users with UID 2748 and 2750 when not running
in -rmtsys mode.
* Add Perl bindings for the user-space cache manager library (libuafs).
* Fixes to the bypasscache feature.
* Remove the obsolete Netscape plugin.
Linux
* Remove Linux 2.2 and 2.4 support.
* Changes to avoid EIO errors with multiple processes doing intensive mmap
writing. (Drop PageReclaim AOP_WRITEPAGE_ACTIVATE.)
* Prevent fakestat data inconsistencies in certain cases (131855).
* Fix dentry leak which can cause a crash on shutdown.
* Improve error reporting when encountering corrupt directories.
* Improve rx error handling in the Linux cache manager.
* Rename kpasswd to kapasswd when packaging RPMs to avoid colliding with
Kerberos kpasswd.
* Do not use the obsolete --enable-largefile-fileservers configure option
when packaging RPMs.
* Use the RemainAfterExit systemd feature to avoid premature exit
when -afsdb is not given, for RPM packages.
* Remove Debian packaging files from the OpenAFS source tree. Debian
packaging files are currently maintained in the downstream Debian
infrastructure.
* Add the sparc_linux26 sysname.
Solaris
* Remove support for all Solaris and SunOS platforms prior to Solaris 8.
* Build 64-bit binaries for Solaris x86 by default.
MacOS
* Stop processing upcalls once rx shutdown starts.
* Enable atomics for the darwin kernel.
* Add a syscall to enable/disable bulkstat at run-time, which is
disabled by default.
FreeBSD
* Use the native kernel module build system instead of an ad hoc
replacement build system.
* Remove FreeBSD packaging files from the OpenAFS source tree. FreeBSD
packaging files are currently maintained in the downstream FreeBSD Ports
Collection.
* Stay up to date with new FreeBSD releases (through 10.3).
NetBSD
* Stay up to date with new NetBSD releases (through 7.x)
* Update to use cprng(9) as the randomness source on NetBSD 6.99/7.x.
* Build system updates for NetBDS 6.99.x
OpenBSD
* Stay up to date with new OpenBSD releases (through 4.7)
AIX
* Updates for AIX support.
* Fix build system for AIX exports.
* Add the uidpag and localuid runtime options to the aklog LAM plugin.
(These runtime options override the use of UID-based PAGs, which were
introduced to appease the CDE screensaver.)
