2006-10-19 <[email protected]>
* ======== Release 6.1.2 =========
* Use ssize_t for return variable from read(2) and write(2) in
mkcodabf. (Phil Nelson)
* Remove unnecessary rpc2/fail.h rpc2/fcon.h includes.
* Release parent when an assertion triggers, this avoids locking
out a user during the boot when venus's RVM layout has changed.
* Remove unnecessary parent recursion code when a conflict is
detected, this is done by the server now.
* Don't return permission denied when we check for file existence.
* Account file data when reporting CML size in cfs listvolume output.

* Return hints for cross directory rename resolution (Adam Wolbach)
* Make cross-directory rename hinting server-side only.
* Fix launching of ASRs for local/global conflicts. (Adam Wolbach)
* Get the fid(s) for local/global conflicts from the cmlent
* Don't assume Coda is mounted at /coda, try to use the configured
location for pioctls.
* Separate worker threads from authentication threads on the server.
* Don't try to be smart and leave the umask alone. (Rune)
* Remove updateclnt/updatesrv dependency on rpc2portmap. (Rune)
* Remove rpc2portmap source, move updatesrv to codasrv-se port.
* Remove win95 (djgpp compiled, dos binary client) code.
2006-08-28 <[email protected]>
* ======== Release 6.1.0 =========
* Rewrite of the application specific resolver (ASR) framework.
(Adam Wolbach)
* Double stack size for Callback threads to avoid stack overflows
on cygwin.
2006-08-25 <[email protected]>
* ======== Release 6.0.16 =========
* Fix client crash during repair introduced in 6.0.15
* Merged 64-bit fixes from Brett Lymn
* Fix many 64-bit issues in the Coda client, 64-bit seems to be
somewhat working now.
* Changes to have the vget upcall fetch the file into cache yet return
* Try to finalize server-server part of a repair.
* Try to not cache attributes from individual replicas.
* Fix libreadline test on FC2 and link libreadline5-dev on Debian.
* Remove prototypes for unused/no longer existing functions. (Rune)
* One small fix for coda.spec to fix the init.d file locations on
OpenSuse. (Jerry Amundson)
* Increase minimum RVM allocation size. (Jerry Amundson)
* Compilation fix for coda with MIT krb5. (Maurice van der Pot)
* Make the test for libreadline find it in /usr/pkg tree if it is
there. (Phil Nelson)
* Add the mkcodabf utility. (Phil Nelson)
2006-05-30 <[email protected]>
* ======== Release 6.0.15 =========
* Make sure we pass valid 'owner' to resolution log entries.
* Weakly equal VVs should not trigger a R/U file conflict.
* Fix large file trickle reintegration.
* Interpret setmode argument in the fix file as an octal value.
* Use unsigned int for partition blocks free/available counts.
* Use unsigned long for partition used/free block counts.
* FC5 compilation fixes that were sent to the bug tracker.
* Allow updates even when the rwcdb is opened read-only.
* Fix rwcdb_read on in-memory records.
* Look for libX11 in /usr/lib as well.
* Remove mmap code in rwcdb.
* Fix kerberos checks in configure (Maurice van der Pot)
* Aggressively disconnect client when tokens expire.
* Close pipe to the parent when we crash during startup.
* Kick the FSO daemon when we hit yellow or red zones.
* Set root directory mode-bits on a new volume to 0755.
* Implemented a new Coda token format.
* Fix pathnames for binaries called by venus-setup.
* FC5 compile fixes
* Add make dist target
2005-10-28 <[email protected]>
* ======== Release 6.0.14 =========
* Different, more backward compatible fix for the incorrectly
packed CML remove operations.
2005-10-21 <[email protected]>
* ======== Release 6.0.13 (dontuse) =========
* Only allow members of the System Administrators group to create
or remove mountlinks.
* Reintegrated remove operations were packed incorrectly and would
trigger spurious conflicts.
* Allow overriding the path-prefix in codadump2tar with an -rn
<prefix> argument. The prefix normally defaults to the name of the
backup volume.
* Do not use red zone/yellow zone slowdown if we are disconnected.
We really only need to wait for background reintegration when we
are write-disconnected.
2005-09-21 <[email protected]>
* ======== Release 6.0.12 =========
* Allow access to cached realms when starting disconnected.
* Allow getacl to work while write-disconnected (for unmodified
directories).
* Drop last remains of the writeback code, this breaks network
compatibility with clients and servers older than Coda-6.0.7.
* Do not cache inode number information of container files in RVM.
This allows backup/restore of venus.cache and associated RVM data
when venus is not running.
* Make sure reintegration will always try to make some progress even
when the estimated bandwidth is so low that no entries are
considered eligible.
* Fixed RPC2 connection entry leaks.
* Avoid closing a random filedescriptor when open fails.
* Avoid a crash in open when locally generated objects are reclaimed
as a result of cache pressure.
* Avoid crash when updating cached status for an object and not all
the data is available yet.
* Added vcodacon, fltk-based codacon implementation. (Phil Nelson)
* Added CML size in bytes to 'cfs lv' output.
* Make sure the servers do not report a conflict for objects when the
parent of those objects is marked as a conflict.
* gcc-4.0 and 64-bit related cleanups. (many from Brett Lymn)
(Not yet enough to make Coda actually work correctly on a 64-bit CPU)
2005-06-07 <[email protected]>
* ======== Release 6.0.11 =========
* Fixed kernel device check in venus-setup. (Maurice van der Pot)
* libc5 compilation fixes. (Dan Fandrich)
* Reintegration of 'mkdir bar; chown foo bar' was incorrectly
considered as a conflicting update.
* Fix iterators to make sure we keep objects pinned down with a
refcount to prevent them from being pulled out when we yield (make
an RPC2 call) during the iteration.
* Send error messages from the backup scripts to root@localhost
instead of the current (/dev/null-ed) addresses in the Coda domain.
2005-04-28 <[email protected]>
* ======== Release 6.0.10 =========
* Fix file resolution bug that was introduced in the 6.0.9 release.
2005-04-27 <[email protected]>

* Darwin patches from Stephen Turnbull.
* heimdal patches for the krb5 support code (Tom Ivar Helbekkmo)
* fixes some compile errors that resulted from the lwp.h cleanups.
* allow codadump2tar to deal with long volume names in dump files.
* rvmsizer now separately shows RVM used for directory contents.
* cunlog now uses the default realm in venus.conf if it wasn't
specified.
* Avoid permission denied errors when an authenticated user revokes
his tokens or when they expire.
* configure should now be able to find libresolv on Darwin.
* Added udev support to venus-setup along with some other cleanups.
* avoid a crash when running cfs fr during reintegration.
* split --with-crypto into individual --with-openssl/krb4/krb5
options.
* added '-port' option to updatesrv to force it to bind to a specific
port.
* Returning 1 as the directory link count so that the find -noleaf
option is no longer necessary.
* Added a pretty much all of the old manpages that I could find.
2005-03-03 <[email protected]>
* codadump2tar and volutil restore no longer break when a volume
name is longer than 31 characters (names will be truncated
though).
* rvmsizer now also shows amount of RVM used for directory data.
* Build fixes for lwp-2.0 changes.
* Using tmpfile instead of mktemp for the temporary file used
during runt resolution.
* Fix permission denied errors for files that are accessible by
System:Anyuser when a user has lost his token.
* Make cunlog use the default realm from venus.conf if the user
hasn't specified a realm.
2004-12-22 <[email protected]>
* ======== Release 6.0.8 =========
* Removed obsolete purgevol script.
* codasrv daemonizes itself.
* Allow '/' characters in volume names in createvol_rep, also don't
assume /vicepa is always a top-level directory.
* Fixed RVM usage estimates that are given when setting up a server,
they were off by quite a bit.
* Changed vice-setup to assume the rootvolume is named '/', and
try to automatically create it.
* Number of CML and hoard entries are now relative to the number of
cache files instead of the cache size.
* Make cfs flushobject recurse across mountpoints.
* cpasswd broke in the last release, fixed.

* ======== Release 6.0.7 =========
* new codadump2tar, takes a 'volutil dump' file and spits out a
tar archive, doesn't yet work for incremental dumps. (Satya)
* Send shutdown and zombie events to codacon. (Phil Nelson)
* Added several manpages in docbook format. We need docbook2man or
docbook-to-man to convert these into *roff.

* createvol_rep doesn't use the VSGDB (E0000XXX numbers)
anymore, servers are now explicitly named;
'createvol_rep <volumename> <server>[/<partition] ...'
* Default rootvolume name is '/'. If /vice/db/ROOTVOLUME
exists we transparently map requests for '/' to the volume
named in the ROOTVOLUME file. (i.e. nothing really changed)
* Correctly swap the ports to network byte order in the DNS SRV
response. (Ivan Popov)
* Ignore realm names starting with a period. (Ivan Popov)
* Fixed cfs forcereintegrate error return code. (Jim Page)

(Write-)Disconnected state after startup.
* When SRV records say that a service is definitely not
available ('.' response) don't fall back on normal DNS host
resolution.

* Removed most of the writeback permits code.
2004-04-20 <[email protected]>

2004-03-19 <[email protected]>
* ======== Release 6.0.5 =========
* An inverted test prevented resolving a realm by ip-address.
* There was a fatal bug when fetching a 0-length file. (Rajesh Balan)
* Forgot to bump the venus.version number to 6.0.4, it is .5 now.

* ======== Release 6.0.4 =========
* Make sure we initialize libresolv before doing hostname lookups.
* Name lookups in /etc/hosts used to fail because of an appended '.'.
* pdbtool group management fixes (adding or removing groups from
groups). Run 'pdbtool cm' to fix the existing pdb database.
* Fixed volume destructor, now realms disappear when all cached
files have been dropped.
* Persistently store a realm's rootvolume in RVM (needed when starting
disconnected).
* Fix some [CODA_](MAXPATHLEN|MAXNAMELEN) confusion.
* Return EPERM when a user tries to set the ACL on a fake directory.
* Slow down client when running low on cachable objects, similar to
the reintegration log redzoning.
* Check the lookaside cache when handling a disconnected fetch.
* IPv6 support for clog, cpasswd, au, auth2, updateclnt, updatefetch,
updatesrv, getvolinfo, rpc2ping, smon2, volutil, cmon.
* Aggregate all anonymous connections for a realm (instead of having
anonymous connections for each local userid)

* MacOS X fixes from William van Etten.
* INSTALL/README.BSD update from Greg Troxel.
2003-09-29 <[email protected]>

before obtaining tokens. This simplifies getting tokens while
keeping passwords safe from a root crontab entry.
clog -as www-data [webuser] < /.../passwordfile
* Fix rounding error in GrowVnodes which was causing a server crash
during backups.
* Runt-resolution fixes.

2003-08-01 <[email protected]>
* ======== Release 6.0.2 =========
* Make sure the server stays responsive while computing SHA
checksums by occasionally yielding to other threads.
* Instantiate a realm in /coda when a user gets tokens.
* Using double fork to let init catch our zombie processes.
* Avoid codacon crash when pathnames are very long.
* Fix '..' traversal across mountpoints which was causing problems
on every system but Linux (which never passes '..' to venus).
* Make sure that updateclnt actually reconnects after the updatesrv
was down for some time.
* Improved performance and importing large groups in pdbtool.
* Returning a fake ACL for fake local objects. Realm mountpoints,
repair related trees, etc. (Ivan Popov)
* Redzone/yellowzone to avoid running a client into the brick
wall of 'no more CML or blocks available' when we are
(write-)disconnected. When the CML or disk fills up we start slowing
down when we are starting to run low on space, and start blocking
mutating threads when space is pretty much exhausted. This way the
reintegrating thread has a chance to catch up.
* Added fts.c/.h when libc doesn't provide it. (Phil Nelson)
* Removed per-user rpc2 connection limit.
* Removed masquerade option (it is now always enabled).

does not purge them during initialization.
* When restarting after failed repair, recover CML linkage to
localized objects.
* Allow for dirty objects without a container file.
* Only allow mountpoints to be created through a cfs ioctl instead of
interpreting magic characters in a regular symlink.
* Venus now allows arbitrary size volume names, the servers don't.
* Empty mountlinks trigger pathname based volume lookups. (Ivan Popov)
* Correctly report disk block usage. (Greg Troxel)
* A newly created /etc/coda/xxx.conf is now actually readable.
* More kerberos fixes (Ivan Popov, Mark Phalan, Rafael Perez)
* Removed libdb 1.85 dependency, related code is now using rwcdb.
* Perform mount syscall from a child process on *BSD systems to avoid
deadlocks during mount.

* Avoid unnecessary conflict as a result of a strict VV test during
reintegration.
* Removed the server's dependency on the VSGDB.
* Several server-server conflict resolution and repair fixes.
* Replaced internal codasrv and venus log-rotation with an external
scripted solution.

2002-12-13 <[email protected]>
* ======== Release 5.3.20 =========
* Don't abort repair when some replicas cannot be found.

* Fixed createvol_rep to deal with spaces in volume names.
* Corrected Linux's devfs aliases in the modules.conf file.
* Fixed occasional memory leak and bad free in venus.
* Added 'masquerade_port' option to venus.conf to force venus to use a
fixed port number when masquerading.
* Kerberos cleanups and improved integration (no more special kauth2
or kclog binaries).
* Reduced the size of CML entries in the client.
* Fixed inverted test that blocked the creation of files named '..foo'
* Keep the vnode bitmaps on the server small, servers would crash when
more than 30000 files are created in a single volume. Now we should
be ok until we hit about 240000.
2002-03-12 <[email protected]>
* ======== Release 5.3.19 =========
* Fixes for createvol_rep script.
* Avoid using hardcoded configuration file location in scripts.
* Avoid uninitialized atime and ctime when fetching an object,
although we don't keep track of these times, it broke make.
* Fixed bad cast from rec_dlist to dlist.
2002-02-01 <[email protected]>
* ======== Release 5.3.18 (unreleased) =========
* Coda servers were doing strncmp instead of memcmp on ip-addresses.
This fixes 'identity-crisis' problems for replicated servers, where
servers didn't know which volumes they were hosting etc. (Ivan Popov)
* A wrong mknod args in the RPM postinstall, we failed to correctly
create the /dev/cfs0 device.
* Some Coda client postinstall fixes for Debian.
* Made ValidateAttrs on the server more resilient to bad input.
* Handle reintegration conflicts when doing a partial reintegration,
instead of endlessly looping.
* Improved devfs support on Linux (Rajesh Balan).
* We had some stupid assumptions about 'equivalency' between C++
classes and C structs which break when compiling with
gcc-3.0, there might be more problems lurking there.
* Windows XP installation fix (Phil Nelson).
* Searching the colon separated CODACONFPATH environment variable for
venus.conf and server.conf configuration files.
* Added some more paranoia checks while parsing the /vice/db/servers
file.
* No longer ordering VRDB entries entries by ip-address. This allows
us to resize a VSG without affecting version-vectors.
* Replaced the codaconfedit script with a C implementation that
searches CODACONFPATH and can be used to query entries as well.
* Venus now gracefully handles the situation where getvolinfo returns
different replicas compared to the cached replication information.
Now we only need add server support for VSG changes and a trigger
that forces venus to make a getvolinfo call and we can start moving
volumes around in the system.
* Added rds_print_stats to the server's printstats output to aid in
finding whether an RVM allocation failure is due to running out of
RVM space, or due to a large defragmentation that cannot be logged
in the RVM log.
2001-11-06 <[email protected]>
* ======== Release 5.3.17 =========
* venus-setup created NOT_REALLY_CODA in / instead of in /coda
(Ivan Popov).
* Avoid killing clients when receiving truncated directory data.
* Block when accessing an uncached object during resolution instead of
failing. This is especially useful during weak-reintegration.
* Added -local flag to cfs lv to avoid client-server rpc2 traffic.
* Fetch data as well as status in write-disconnected mode, the dirty
status-only object would prevent subsequent data-fetches until
successful reintegration completed.
* Added venus.conf option 'validateattrs' to limit piggybacked fids
during validate attrs to help reducing IP layer fragmentation.
* Another new venus.conf option 'serverprobe' to increase server probe
intervals (keeps firewalls from dropping masqueraded connections).
* venus.conf.ex file now defaults to turning on both masquerading and
using private mmap's for RVM.
* Disallow unlinking special names with 'cfs rmm'
* Optimized local-global fid replacement.
* Removed /dev/cfs0 from RPM package to allow unpacking the RPM on devfs
enabled systems, we don't fix up the devfs autoloading stuff yet.
* Moved /usr/bin/replay to /usr/bin/coda_replay to avoid name conflicts.
* Added getvolinfo program to be useful when debugging volume mounting
problems.
* Added the missing fflush back in the server logging.
* Fixed createvol_rep to disable resolution logging when creating singly
replicated volumes.
* Fixed possible errors during runt-resolution.
* Added assert to the server when not all hostnames in a VSG can be
resolved.
* Avoid servers getting stuck in file-creation when there are
pre-existing files in /vicepa.
* Always pre-allocate fids with the maximum possible stride, will become
useful when we allowing modifications to a volume's replication
group. However, any replicated volume over a mix of old and new
servers has a slightly higher probability on getting unwanted
fid-collissions.
* Reduced server memory usage during reintegration.
* gcc-3.0 compilation fixes.
* Lots of cygwin/win32 patches (Phil Nelson).
* Fixed the test for readline library version (Phil Nelson).
* Fixed detecting libdb3 with db 1.85 'compatible' API (Russ Mennie).
* OpenBSD patches (Jeff Bachtel).
2001-06-12 <[email protected]>

* Fix wild iterator when killing off connection groups.
* Found server memory leak in the access validation path.
* Addressed possible race in server down handling.
* Not returning ENOENT when testing inconsistent files with
access(F_OK).
* More effectively invalidate kernel caches for dangling symlinks as a
result of conflicts.
* Remove some unused code.
* Allow server-server repair with only one existing replica, needed
for repairing conflicts after running out of diskspace.
* Code cleanups for gcc-3.0 prerelease.
* Added "skip volumes" argument to norton-reinit -load.
* Reduce stack usage when printing name contexts.
* The 'change id' function of pdbtool would silently corrupt the pdb
databases, group owner id's were not updated, users were missing
as members from groups. Group could become a member of a user.
Hueristics to fix these corruptions are added to the 'pdbtool cm'
functionality.
2001-03-27 <[email protected]>
* ======== Release 5.3.14 =========
* Reintroduced VSGs in venus.

in the low end of the priority queue.
* Fixed PackVS bug when hosts in an mgrp are not all packed into the
beginning of the hosts array.
* Merged decision to use vol->AddCOP2 into vol->COP2.
* Fixed signal handler so that simply sending SIGHUP rotates the
logfiles without crashing venus.
* Replaced a couple of uses of mktemp() with tmpfile().
* Removed most redefines of VSG_MEMBERS, this constant should now only
be defined in vcrcommon.rpc2.

* Added check for -fno-operator-names (Timothy Wood).
* Added warning when gethostbyname(myname) returns a 127.x.x.x
address.
* Added warning when db/servers has a server with `reserved' hostid
(0, 127 or 255).
* Added ipaddress=xxx.xxx.xxx.xxx server.conf option to override
incorrect gethostbyname(myname) results.
* Fixed server hostTable iterators.
* Allow server to bind to IN_ADDR_ANY when not running multiple
servers on the same machine.

2000-05-01 <[email protected]>
* ======== Release 5.3.7 =========
* Bumped the version number to 5.3.7.
* Many changes to the server setup scripts (Phil Nelson).
* Allow for overriding hardcoded paths in server programs by using
config files in /etc/coda to configure (multiple) servers. (Phil).
* Locked up updatesrv to serve files from /vice/ only. Also added an

occasionally cancelled out the wrong operations.
* Correctly handle writeback caching on replicated volumes
(Shafeeq Sinnamohideen)
* Filenames in repair files sometimes got truncated.
2000-02-04 <[email protected]>
* ======== Release 5.3.5 =========
* Lots of fixes for Solaris sparc & i386 (Phil Nelson).
* CML entries were not frozen during trickle reintegration and repair
* sessions. This lead to problems with failed backfetches, bad
reintegrations of owrite files, and crashes during log optimizations.

* Fixed a crash on 'cfs rmm dir/'
* Skipping non-cacheable objects during the hoard walk.
* Got rid of a double free (and crash) in the sftp code.
* Added optional private rvm mappings. Huge performance wins when
enabled, but only works for rvm-files. (Phil Nelson)
* Fixed the year being printed as 100 in the logfiles in 2000.
* Build cleanups, moved kernel-src and lwp to separate packages.
* Switched codaservers to exit by default, added a -zombify flag and
test for /vice/srv/ZOMBIFY to switch back to the endless sleep.
* Cleanups in backup and setup scripts. (Kurt Huwig and David J. Graff)
* Added more options for venus.conf.
* Added support for multi-level incremental backups.

- Truncating a file while disconnected caused venus to crash.
- A memory leak was triggered by failing SFTP transfers, this has
been partially fixed.
- Fixed a crash that occurred after a double kill of a namecontext
during a hoard walk after token expiry.
- Collapsed hoard namecontexts were never re-expanded due to some
optimizations.
* Cleanups & features:
- Thanks to a huge patch from Jozsef Kadlecsik, many #ifdef's in
the code are now based on autoconf detected features instead of
operating system.
- Reworked the init scripts a bit.
- New configuration file, $sysconfdir/coda/venus.conf, which
allows persistent changes to rvm/logfiles/cache directory
locations, which should allow distributions to push Coda into
their standard directory hierarchy.
- Fixed a (false) conflict that was created after a token expired.
- Several compiler errors/warnings fixed, thanks to Troy
Benjegerdes and Kurt Garloff.
- Phil Nelson has been making many fixes and updates for the

important ones are listed below.
- New directory handling code, which does not corrupt the directory
structures on the server and has better `bad-directory' checking and
handling code.
- New RTT and bandwidth estimates in the rpc2 code, currently these
estimates are used by SFTP and venus, RPC2 itself remains to be
converted to the new scheme. Little timing/correctness errors were
fixed.

apps around it (clog, cfs, etc.).
* and more....
