Message changed from an - Error to a Warning. - - * (sfs_ops.c) added linkx fstype. linkx is the same as link but - it also checks that the target exists. This makes it useful for - wildcard map entries. - - * (wire.c) applied changes from Dirk Grunwald. Now stands a - better chance of correctly determining the network name. - - * (map.c) changes in timeout_mp to cause second and subsequent - backgrounded unmount attempts to backoff and so reduce the chance - of running more than one backgrounded unmount at a time. - - * (misc_rpc.c) bug fix from Martyn Johnson to avoid xdr_free'ing - the wrong piece of memory. This was causing random core dumps, - often with a stack trace through pickup_rpc_reply. - -Sun Sep 15 21:16:38 1991 Jan-Simon Pendry (jsp at achilles) - - * Release 5.3 alpha 14. - - * (os-osf1.h) merged in OSF/1 support. - -Sun Aug 4 18:25:04 1991 Jan-Simon Pendry (jsp at achilles) - - * (os-stellix.h) merged in Stellix support. - - * (os-u4_2.h) merged in Ultrix 4.2 support. - - * (host_ops.c) made TCP the default transport protocol. Define - HOST_RPC_UDP somewhere to get UDP transport. - - * (many) added support for ${remopts}. Suggested by Steve - Heimlich. remopts is the same as opts, but is used when the - remote server is not on the local network.

This is - used by nfsx_ops.c. - - * (mapc.c) uses new RE_HDR abstraction coping with systems which - already have the re package installed. - - * (nfsx_ops.c) automatically generates a suitable sublink to make - things work. Remounts now work correctly, but are done in the - foreground so there is a possibility that things may hang. This is - too hard to do differently. - -Wed Apr 3 17:49:05 1991 Jan-Simon Pendry (jsp at achilles) - - * (nfs_ops.c) HAS_NFS_QUALIFIED_NAME is a new compile time switch - which puts a qualified domain name into the RPC authentication - instead of using the default value. Abstracted this out into new - routine called make_nfs_auth(). - - * (afs_ops.c) fixed bug which caused spurious ENOENTs to appear. - this was caused by some code motion which also got slightly - altered int the process. moral: don't make two changes at once. - -Sun Mar 17 12:05:27 1991 Jan-Simon Pendry (jsp at forest) - - * Release 5.3 Alpha 11. - - * (amq.8) Updated. - - * (amq.c) Added new -v option which displays the version number of - the target Amd. Also added support to Amd and reworked newvers - script. Got rid of rcs_info.c. - - * (mk-amd-map.c) Changed name of remove function to avoid clash - with ANSI C. - - * (wire.c) Fixed to work with new 4.4BSD sockaddr's. - - * Changed const to const everywhere and added new define in config.h. - - * (mk-amd-map.c) New -p option which just writes the output to - stdout. Useful for making NIS or Hesiod maps. - - * (amdref) Small updates and clarifications. - -Sat Mar 16 20:35:17 1991 Jan-Simon Pendry (jsp at forest) - - * (amq_subr.c) Flush request now flushes all internal caches. - - * (amq_subr.c) Changed xdr_amq_mount_tree to return only the - required sub-tree. - - * (ifs_ops.c) Added missing return 0; to ifs_mount. - -Sat Mar 9 19:31:25 1991 Jan-Simon Pendry (jsp at forest) - - * (get_args.c) Output the primary network interface information - with the -v option. - - * (mapc.c) Fixed spurious warning about "root" map not supporting - cache mode "all".

The C library routine is not used because it - uses a static buffer and it takes a structure argument on some - machines and unsigned longs on others. This confuses the hell out - of some compilers and causes SEGVs. - - * task_notify becomes do_task_notify to avoid clash with Mach. - - * (mntfs.c) In realloc_mntfs, the private data field wasn't being - cleared out when the mntfs object was being re-used. This meant - that the data might be used for the wrong mount, so causing - various obscure errors. - - * (info_file.c) Reworked to provide support for map cache "sync" - option. - - * (mapc.c) Added new "sync" option to map cache. This ensures - that the cached data doesn't become stale wrt the source. - Currently this isn't implemented for passwd and hesiod maps. - -Wed Feb 27 11:38:07 1991 Jan-Simon Pendry (jsp at forest) - - * (afs_ops.c) Fixed pid put in fs_hostname for toplvl mount. - -Sun Feb 24 19:37:55 1991 Jan-Simon Pendry (jsp at forest) - - * (wire.c) New module which determines the name of the primary - attached network. This could be used to determine which - server to use. - - * (srvr_nfs.c) Changed mount daemon port mapping caching. This is - now much more eager to recompute the mapping than before. Will - also now work even if pinging is switched off (for example "tcp"). - - * (info_nis.c) Added back old NIS reload code to allow NIS maps to - support "regexp" caching. - - * (mapc.c) Added support for "regexp" caching. This is a type of - map cache where the entries are all REs to be matched against the - requested key. This implies "all" since all the keys must be - loaded for the search to work. - -Sat Feb 23 15:32:43 1991 Jan-Simon Pendry (jsp at forest) - - * (afs_ops.c) Avoid spurious error messages about discarding a - retry mntfs. - - * (amq_subr.c) Removed inet_ntoa call due to disagreement between - gcc and libc about 4 byte structure passing. - - * (xutil.c) Changed way initial logging is done to make command - line more usable. Default logging flags are set statically and - can then be modified by -x options. At the end an additional call - to switch_option is made to initialise xlog_level_init. - - * (umount_fs.c) ENOENT now treated the same as EINVAL. If the - filesystem gets removed and the mountpoint deleted then just - assume the filesystem isn't there - which it isn't. - - * (host_ops.c) Now copes with unmount failures by attempting to - remount the filesystems which had been unmounted. - - * (host_ops.c) Added check during fhandle collection to detect - duplicate entries in the export list (from Stefan Petri). - - * (nfsx_ops.c) Reworked to correctly keep track of what is and - isn't mounted. - -Sun Jan 27 16:58:02 1991 Jan-Simon Pendry (jsp at achilles) - - * (misc-next.h) Added missing NeXT config file. - - * Merged Harris HCX/UX support from Chris Metcalf. - - * (ifs_ops.c) added ifs_fmount entry point to keep nfsx_ops happy. - -Sun Jan 13 18:19:19 1991 Jan-Simon Pendry (jsp at beauty) - - * (nfsx_ops.c) play with opt_fs field to make sure it is unique. - -Fri Dec 21 15:35:45 1990 Jan-Simon Pendry (jsp at forest) - - * Release 5.3 Alpha 9. This is still not Beta! - - * (host_ops.c) use normalized hostname in mtab entries, from - Chris Metcalf. - - * (map.c) enum ftype -> ftype, from Andrew Findlay. - -Mon Dec 17 01:11:25 1990 Jan-Simon Pendry (jsp at beauty) - - * (amdref.texinfo) merged in fsinfo documentation from Nick. - -Sat Dec 15 15:39:07 1990 Jan-Simon Pendry (jsp at beauty) - - * (clock.c) minor tweaks to messages. - - * (sfs_ops.c) make the opt_fs field unique, rather than always - ".", but make sure it still begins with a "." to avoid a clash - with any other existing mounts. - - * (amd.c) changed way local IP address is obtained to avoid using - a call to the name server. It was observed that if the power to - the building goes and everything reboots simultaneously then there - would be a good chance that the nameserver would not recover - before Amd on another machine required it. This happened :-) Now - use the RPC get_myaddress call. - - * (info_hes.c) added hesiod_reload code from Bruce Cole. - Optionally compiled when HAS_HESIOD_RELOAD is defined. - - * (amq_subr.c) fix "security" check. - - * (amq.c) make sure a privileged port is allocated. In fact - RPC3.9 and newer make this guarentee but older versions don't so - we do it here. - -Sun Dec 2 21:30:07 1990 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) fixed problem with pointer pre-increment. - -Mon Nov 19 00:31:28 1990 Jan-Simon Pendry (jsp at achilles) - - * (nfs_ops.c) saved filehandle with mntfs structure. this allows - nfsx unmounts to be undone even if the filehandle cache has lost - the entry. all of this is bogus and deserves a rewrite... - -Sun Nov 18 22:55:43 1990 Jan-Simon Pendry (jsp at achilles) - - * (nfsx_ops.c) now handles mounts of root filesystem correctly. - - * (afs_ops.c) fixed dfs_ops definition to call toplvl_mounted when - done, so making sure that a map cache reference is set up. - -Sun Nov 11 21:09:34 1990 Jan-Simon Pendry (jsp at achilles) - - * (fsinfo/wr_fstab.c) has per-ostype fstab rules. - - * (fsinfo/fsi_lex.l) now works correctly with flex. - -Mon Nov 5 00:08:30 1990 Jan-Simon Pendry (jsp at achilles) - - * Release 5.3 Alpha 8. No more new features from now to 5.3Rel. - Call next one Beta. - - * (amdref.texinfo) more updates. - - * (info_union.c) reload routine now adds a wildcard pointing to - the last named directory so that new files get created correctly. - -Sun Nov 4 22:02:50 1990 Jan-Simon Pendry (jsp at achilles) - - * (os-u4_0.h) Ultrix 4.0 support merged. - - * (os-utek.h) Utek 4.0 support merged. - - * (amdref.texinfo) fixed & updated. - - * (nfsx_ops.c) reworked string munging to prevent ..//.. strings - from occuring. - - * (util.c) am_mounted now correctly updates the am_node for - duplicate mounts. - - * (afs_ops.c) added union fstype. derived from "toplvl" except it - causes all the filesystems to be mounted. cannot be used for - filesystem types whose mounts may be defered (eg nfs) since it - doesn't retry the mounts. - - * (info_union.c) map type for union fstype support. currently - can't handle being given automounted filesystems - causes a - deadlock. - -Sun Oct 21 22:56:16 1990 Jan-Simon Pendry (jsp at achilles) - - * (fsinfo/*) finally integrated the fsinfo package. currently no - documentation or man page. this is a pre-req to getting mmd up. - -Sun Oct 14 20:02:11 1990 Jan-Simon Pendry (jsp at achilles) - - * (amdref.texinfo) reworking of documentation continues. - - * (clock.c) reschedule_timeouts() now called in the event that the - system clock goes backwards. this is possible during the average - bootstrap juggling act with timed/xntpd etc. especially useful if - your machines TOY clock gets way ahead of time. - -Sat Oct 6 19:57:55 1990 Jan-Simon Pendry (jsp at achilles) - - * (map.c) when expanding the filehandle for a server which is - down, don't update the ttl on the original node unless a new node - gets allocated. this should give the original mount a chance to - go away as soon as the server comes back. - - * (arch, os-type) Updated. - - * (nfs_ops.c) Added "noconn", "spongy" and "compress" mount - options for 4.4 BSD. - -Sun Sep 30 18:37:54 1990 Jan-Simon Pendry (jsp at beauty) - - * Release 5.3 Alpha 6. - - * (util.c) domain_strip now doesn't leave partial domains behind. - if it can't strip the complete domain it leaves the string untouched. - - * (restart.c) remember to initialise opt_opts field from mtab. - - * (nfs_ops.c) supports "nocto" option for SunOS4.1. - - * (os-irix.h) new SGI Iris port. - - * (os-next.h) new NeXT port. - - * (os-dgux.h) new DG/UX port. - - * (many) fixed problem where mf_opts was being used for two - different purposes. Now have two fields. - - * (mapc.c) error map prints error message whenever used. - - * (mapc.c) wildcard code rewritten. - - * (util.c) slpit into two parts - some code now in xutil.c. This - is used by mmd (not yet shipped). - -Sun Aug 19 19:58:16 1990 Jan-Simon Pendry (jsp at achilles) - - * (srvr_nfs.c) reduce verbosity of "nfs server yoyo is ok" messages. - - * (opts.c) fix deslashification in expand. - - * (nfs_start.c) amq registering done just before the server kicks - in. running amd with nothing to do leaves the portmapper in peace. - - * (mapc.c) bootstrap code abstracted to allow AMQ_MOUNT entry point. - - * (nfsx_ops.c) new filesystem type, supporting groups of nfs - mounts. needs abstracting to allow groups of (*) mounts. - - * (am.h, *_ops.c) am_ops structure changed; corresponding changes - in the filesystem implemention source. Change was to allow nfsx - filesystem implementation. - - * (amd.c) hostname defaults to "localhost" startup code re-ordered - so that logging still works in case things go wrong early. - - * (am_ops.c) new routine to print list of available fs types; used - by the -v option. - - * (info_file.c) bug fix to make reloads work correctly. - - * (mtab_file.c) does locking on single write, to avoid trashing - mount table when a mount and unmount are done at the same time. - - * (mount_fs.c) automount hack removed since afs_ops no longer - needs it. - - * (afs_ops.c) split "auto" into several other filesystem types. - Now much cleaner. - - * (amq.c) new -M option. - - * (amq_subr.c) support for AMQ_MOUNT added. - - * (amq.x) new AMQ_MOUNT RPC call allows mount map entries to be - passed in at run-time. Automount points can now be added - dynamically, but not yet deleted. - -Sat Jun 23 22:12:48 1990 Jan-Simon Pendry (jsp at beauty) - - * Release 5.2 for Berkeley. - - * (*) Re-organised source code layout. Now much more complicated. - - * (map.c) code which flushed the kernel name cache is not really - needed now that the modify times on the automount directories are - correctly updated so ifdef the whole lot. Remove later... - - * (map.c) make sure that the automount directories modify times - are updated when a change occurs so that the nfs client code can - decide when to update its name cache. - - * (srvr_nfs.c) fixed bug which caused mounted filesystems to - appear down when they were up. - - * YP becomes NIS. - -Mon May 28 19:50:34 1990 Jan-Simon Pendry (jsp at achilles) - - * (amd.tex) substantially updated with more explanation of the - theory and more examples. - - * (nfs_stubs.c) statfs now claims to have a single used block. - Avoids ambiguity between 100% and 0% full. - - * (nfs_stubs.c) changed to allow the size of symlinks optionally - to be accurate wrt the length of the string returned. Optional - because it is cheaper to ignore the length when doing a getattr - and just send any length for the readlink. However, this breaks - on some systems (e.g. Ultrix). - - * (mount_fs.c) automount points get marked type "nfs" instead of - "ignore". This is to fix an interaction with getwd(). Can go - away when getwd() gets re-written. Really only applies to SunOS4 - but change applies to everything to keep consistent across platforms. - - * (mount_fs.c) abstracted out mount options into a table and - corresponding loop. - - * (srvr_nfs.c) make sure portmap information is available when - needed, not just after a ping has succeeded. This needed changing - after the ping algorithm got changed. - - * (mntfs.c) fixed incorrect reference to mf_error instead of mf_flags. - - * (nfs_start.c) keep track of number of fds in use, so don't run - select on system maximum (which is bad news if you have a large - system maximum). - - * (host_ops.c) new NFS tree mount filesystem type (ala Sun -hosts). - - * (nfs_ops.c) abstracted out NFS mount code to support host_ops. - - * (afs_ops.c) dfs_readlink now returns the am_node, instead of the - link. This allows getattr to return the correct set of attributes - so keeping Ultrix happy. - - * (afs_ops.c) Make certain the hostname field given to mount() - does not get too long - otherwise random EINVAL errors occur. - - * Putting closing comments on all #endif's - -Sun May 13 16:07:21 1990 Jan-Simon Pendry (jsp at achilles) - - * (srvr_nfs.c) second rewrite of NFS ping algorithm. - -Sun Apr 29 21:12:33 1990 Jan-Simon Pendry (jsp at achilles) - - * (nfs_stubs.c) re-arranged readlink code to avoid need to - pre-mount a direct filesystem whenever possible. - - * (host_ops.c) finally incorporated new module to support /net - mount point. - -Sat Mar 24 13:18:47 1990 Jan-Simon Pendry (jsp at achilles) - - * (nfs_stubs.c) workaround added to rename entry point to avoid - arguments with NFS client code. - - * (srvr_nfs.c) changed the way NFS pings are done and cleaned up - the process for deciding when a server is up or down. Now there - is just a simple time limit on a reply from the server. The limit - is adjusted depending on whether the state of the server is known. - - * (opts.c) fixed bug with ${var/} expansion et al. Added ${varN} - N = 0..7 for use as scratch variables. - - * (mntfs.c) fixed bug in dup_mntfs(). - -Thu Jan 11 16:56:41 1990 Jan-Simon Pendry (jsp at achilles) - - * Release 5.1c. - - * (amq*) has new options. -f flushes the map cache and -m prints - information about mounted filesystem and fileservers. - -Tue Jan 2 14:44:21 1990 Jan-Simon Pendry (jsp at achilles) - - * (util.c) am_mounted() patches the path for "direct" mounted - filesystems - cosmetic. - - * (afs_ops.c) when possible sets a small kernel attribute cache - timeout on the automount points. - - * (nfs_stubs.c) delete() and rmdir() operations implemented. Used - when a mount point is timed out so the kernel name cache gets to - know about the changes. Fixes most ESTALE errors. - - * (nfs_stubs.c) New do_readlink() function added. This is used to - make sure that a filesystem is mounted at the time a link is read - in the case of "direct" mounts. Done so that the length of the - link is available when the initial getattr is done on the mountpoint. - - * (sfs_ops.c) Changed implementation to avoid race conditions. - The link target is re-arranged so that sublink points to the - target and fs always points at ".". - - * Fixed mount flag bug on Ultrix. - - * Added support from Sjoerd Mullender for Alliant FX/4 and Encore - Multimax. - -Thu Dec 7 17:55:29 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) dfs_readlink now does a new_ttl on the node it - returns. - - * (afs_ops.c) next_nonerror_node now implements the task after - which it is named. - -Tue Nov 28 17:20:52 1989 Jan-Simon Pendry (jsp at achilles) - - * Release 5.1b. - - * (restart.c) Generates link nodes for any unrecognised filesystem - types and then marks them so that they are never deleted (since - they could never be automounted later). - - * (os-*.h) Irrelevant #undef's deleted. - - * (arch) Now knows about AIX on RTs. - - * (amq.c) Rationalised the output. Now only gives you what you - asked for. - - * (am.h) New macro: FSRV_ISDOWN(fs), which checks whether a - fileserver is down. - - * (afs_ops.c) When a mount fails due to a timeout the underlying - filesystem is ripped away and replaced with an error fs. This - avoids the possibility of being left with a single error reference - to a valid mounted filesystem. - -Thu Nov 23 18:04:29 1989 Jan-Simon Pendry (jsp at achilles) - - * (nfs_start.c) Re-order bootstrap sequence to avoid potential - deadlock if restart() ends up accessing one of the automount points. - - * (amq.c) Don't produce default mount output if one of the -l, -x - or -D options was used. - - * (umount_fs.c) Add alternative unmount routine for 4.4 BSD. - -Mon Nov 20 16:22:50 1989 Jan-Simon Pendry (jsp at achilles) - - * (os-bsd44.h) Fixed redefinition of UMOUNT_FS. - - * (info_ndbm.c) Added missing #include <sys/stat.h>. - - * (mapc.c) Fixed typo in ifdef around gdbm config entry. - -Sat Nov 18 16:39:13 1989 Jan-Simon Pendry (jsp at achilles) - - * (util.c) If "/" is automounted, make sure it is never timed out. - - * (mtab.c) Missing clock invalidation added in read_mtab (from a file). - - * (mntfs.c) realloc_mntfs simplified. - - * (map.c) Closed a race condition during shutdown when second and - subsequent duplicate mounts were deleted prematurely. - - * (afs_ops.c) Duplicate mounts are now given the correct return - code. - -Fri Nov 17 18:58:18 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.1 Release. - -Thu Nov 16 17:57:02 1989 Jan-Simon Pendry (jsp at achilles) - - * (mntfs.c) Make sure inherit mntfs structures are not cached - after last reference; otherwise a second reference to the - inherited filesystem will get stuck on the inherit rather than the - (now) fully mounted filesystem. - - * (am.c, nfs_start.c) After forking the server, make sure the - parent does not exit until the automount points are mounted. This - allows a clean sequence during system startup. - - * Initial port to 4.4 BSD. Several new configuration abstractions - were added to make this port possible. - -Thu Nov 9 21:42:14 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c, opts.c) Added map logging to facilitate mount map - debugging without needing a -DDEBUG version of Amd. - - * (afs_ops.c) Make sure the length of the fs_hostname mount - parameter does not exceed MAXHOSTNAMESZ. - -Wed Nov 8 13:44:02 1989 Jan-Simon Pendry (jsp at achilles) - - * Change the message log format to indicate the severity of the - message to allow simpler analysis of the log file. - -Tue Nov 7 14:11:36 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 11. - - * (os-bsd44.h) Initial guess at 4.4 BSD definitions. - - * (os-aux.h) Port for Macintosh II from Julian Onions. - - * (amq.c) Output formats cleaned up. AMQ_MNTTREE is still broken - in amq_subr.c though. - - * (afs_ops.c) If a mount timed out, for example an NFS server was - down at the time, it was possible for the error code to remain - unset thus jamming that mount node in a state from which it could - not recover. Just make sure that the mf_error field gets filled - in when an error occurs. - - * (afs_ops.c) strsplit is run over /defaults to avoid problems - with whitespace creeping in. - -Sun Nov 5 11:50:51 1989 Jan-Simon Pendry (jsp at achilles) - - * (util.c) am_mounted: Added missing initialisation of stats.s_mtime. - -Fri Nov 3 17:33:02 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 10. - - * Changed the copyright. - -Thu Nov 2 17:07:53 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 9. - - * (opts.c) new option syntax: == != := - - * (nfs_ops.c) Less caching of filehandles. Now cached errors are - discarded after use. - - * (mtab.c) now attempts to deal with a lack of open file slots (ENFILE). - - * (mount_fs.c) automount entries in the mount table now have a - dev= entry in the same way as NFS and UFS. - - * (mntfs.c) mntfs nodes are now cached after the last reference - and discarded <ALLOWED_MOUNT_TIME> seconds later. This avoids - thrashing during a mount. - - * (mapc.c) map default cache mode is now selected with - "mapdefault", not "default" - - * (amd.tex) numerous clarifications. Still more work required... - - * (amq_subr.c) now allows the -x option of amq to operate. - - * (afs_ops.c) afs_bgmount now keeps track of which filesystem - needed retrying and ensures that the mount node in the - continuation correctly points at an unmounted filesystem. This - fixes a problem whereby a valid mounted filesystem could appear to - have failed to mount. - - * Configure now gives more of a running commentary and checks - whether os-type and arch actually worked. - - * Allow spurious ';'s in a mount location. - -Fri Oct 27 14:03:31 1989 Jan-Simon Pendry (jsp at achilles) - - * foo=blah changed to foo:=blah, foo==blah and foo!=blah. - - * -l stderr changed to -l /dev/stderr. - -Thu Oct 19 15:34:28 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 6. - - * LOG_INFO messages have been rationalised so that some - statistics, graphs and so on can be generated. - - * Transaction ID's for RPC calls are now allocated by the - individual callers, rather than from a central pool. This - decreases the load on mount daemons and NFS servers since the - same XID is used for retries when needed. - - * Many fine details of the new data structures have been changed. - Some areas have been optimized. - -Fri Oct 13 12:31:26 1989 Jan-Simon Pendry (jsp at achilles) - - * Restart code re-implemented to work with the new data structures. - - * Fine tuning applied to new NFS server modeling code. - -Thu Oct 12 15:57:24 1989 Jan-Simon Pendry (jsp at achilles) - - * Added ${/var} and ${var/} variable expansions. The first gives - the "basename" component of the variable, the latter gives the - "dirname" component. Additionally, spurious /'s are deleted after - the variable expansions is complete. - - * Added new -C option to allow the machine's cluster name to be - given to amd. ${cluster} fetches the value and can be used as - another selector. - - * Broken the major data struct (am_node) into three layers: - am_node (one for each automount node), mntfs (one for each mounted - filesystem) and fserver (one for each file server). Machine - up/down state is maintained in the fserver layer. Filesystem - mount/unmount state is maintained in the mntfs layer. This change - fixes the last known major problem caused by the lack of a central - focus for filesystem and fileserver status. There is a dummy file - server layer for local filesystems (ufs, link, program, error). - -Tue Oct 10 11:15:42 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 5. - - * (nfs_ops.c) the filehandle cache is now flushed when a - filesystem is unmounted. This avoids ending up with stale - information if a server bounces. - - * (clock.c) new module to implement callouts. Many other - routines changed to use callouts instead of messing with ttl - fields. - -Sun Oct 1 17:08:20 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 3 & 4. - - * Numerous cleanups. - -Wed Sep 13 14:30:05 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 2. - - * (nfs_ops.c) portmap information is not remembered beyond the - basic filehandle cache interval. That avoids problems when a new - portmap and/or rpc.mountd is started and the bound port changes. - - * (mapc.c) cache reloads are automatically done every hour. - - * Removed xlog macro in favour of plog() so that the log level - can be reflected through to syslog(). log() routine renamed to - plog() which takes an extra parameter indicating the log level. - -Tue Sep 5 20:00:19 1989 Jan-Simon Pendry (jsp at achilles) - - * (nfs_ops.c) when a server is known to be down, any cached file - handles and port mapping informaton is flushed since that may have - changed when it comes back up. - - * (map.c) timeout no longer attempts to unmount a hung mount point. - -Mon Sep 4 14:49:18 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) a mount node which timed out during mount is now - retained for the normal timeout interval rather than for a short - period. This avoids wasting time retrying mounts from a server - which is down. - - * (afs_ops.c) hung mounts are now detected and not used as a - duplicate mount - something which defeated the replacement fs - scheme. - - * (nfs_ops.c) keepalive's now back-off when a server has gone - down. - -Thu Aug 31 21:18:35 1989 Jan-Simon Pendry (jsp at achilles) - - * 5.0 Patchlevel 1. - - * Fixed several bugs which showed up in the keepalive - implementation when a gateway went down causing - a different sequence of errors than usual. - -Wed Aug 30 11:29:21 1989 Jan-Simon Pendry (jsp at achilles) - - * (amq.x) now uses a Sun assigned program number. - - * Revision 5.0 - can now start using metaconfig. - -Tue Aug 29 14:36:48 1989 Jan-Simon Pendry (jsp at achilles) - - * (os-u3_0.h, os-type) now knows about DECstations (mips). - - * (nfs_stubs.c) Added hooks to readlink entry point to call - per-fs readlink routine if it exists, otherwise old behaviour. - - * (afs_ops.c) Added implementation of "type=direct". This is - the same as "type=auto" but is itself the link to the - mount point, rather than being a directory containing a list - of links to mount points. - -Mon Aug 28 17:48:15 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) Changed readdir to workaround a problem on - ultrix 3 where it seems to forget that eof has been reached. - -Thu Aug 24 15:17:55 1989 Jan-Simon Pendry (jsp at achilles) - - * Created "beta16". - - * (afs_ops.c) /defaults is located along with every key. - this makes it possible to update the /defaults in - a map and get to use it. - - * (mapc.c) added map cache synchronization support. if - a file or ndbm map is updated the cache is junked so avoiding - things getting out of sync. - -Wed Aug 23 19:17:52 1989 Jan-Simon Pendry (jsp at achilles) - - * (os-u3_0.h) new file to support Ultrix 3.0 - - * (opts.c) allow environment variables to be accessed via - the same ${env} syntax used for options & selectors. - -Tue Aug 22 13:19:49 1989 Jan-Simon Pendry (jsp at achilles) - - * (opts.c, get_args.c) added support for kernel architecture - type to allow /usr/kvm to be automounted under SunOS 4.x. - - * (os-xinu43.h) updated for june '89 release of MORE/bsd. - - * (opts.c) fixed memory allocation problems where some strings - may not have been strdup'ed before they were free'ed so causing - the malloc arena to get into a twist. This caused core dumps on - some machines and infinite loops on others. - - * (*.c) clock handling is now done by a macro. Global variable - clock_valid is > 0 (ie the time) when valid, 0 if invalid. - - * (map.c) timeout code survived a complete rewrite and is now - O(n) rather than O(n^2). - - * (info_hes.c) new database hooks for Hesiod nameserver. - - * (get_args.c) the local sub-domain is picked up from the - hostname if it is not specifed with -d. The subdomain is - then stripped from the hostname. - - * (am.c) when a SIGTERM is received, an immediate abort - occurs - only the top-level automounts are unmounted; all - other mounts stay -- use amd -r to restart. - - * (afs_ops.c) cleaned up key prefix handling. Again updated - the "hostname" string passed to the kernel so that includes - the hostname, pid and mount point. - -Tue Aug 8 16:05:23 1989 Jan-Simon Pendry (jsp at achilles) - - * (nfs_ops.c) changed the way the file handle cache is managed. - No longer gets a race condition between something entering the - cache and being used and discard. - -Tue Jul 25 20:40:51 1989 Jan-Simon Pendry (jsp at achilles) - - * (map.c) changed fh_to_mp2 so that it does not return - ESTALE during shutdown. it returns ENOENT instead which - avoids thrashing with the kernel. - -Sun Jul 23 15:06:10 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) make sure the incoming key from the kernel - does not contain any characters which could cause trouble - during macro expansion (such as `"! etc). - - * (afs_ops.c) fixed contruction of "mtab" entry. - -Fri Jul 21 11:01:05 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) some changes to support the new startup - shutdown scheme. - - * (map.c) startup and shutdown are now done using the - standard interfaces. Startup is done by creating a - private cache map ";root;" and then doing lookups - on all the names in it. Shutdown is done by forcibly - timing out all the mount points including the automount - points. - - * (info_*.c) modified to provide interface required by - mapc.c module. - - * (mapc.c) new module to implement map caching. Caching - can be controlled by an fs option. "all" means cache - the entire map (if possible). "inc" means cache things - incrementally. "none" means never cache things. Each - map type has a default caching mode which is used if - cache option "default" is used. - -Wed Jul 19 16:14:52 1989 Jan-Simon Pendry (jsp at achilles) - - * (sched.c) implements a general sleep/wakeup scheme and uses - it for sub-process handling. - - * (nfs_start.c) task_notify() called from where it used to - be called. - - * (nfs_ops.c) now implements a non-blocking rpc library. - Everything in nfs_ops was changed to use it. This should - not be in this file and will be moved later. - - * (map.c) if a mount point times out and it is deferred then - issue a wakeup so that it can be retried. - - * (map.c) when creating a new mount point fetches the entry - "/defaults" from the associated map if no other options are - specified. - - * (am.c) implements the -p (print process id) option. - - * (afs_ops.c) a mount attempt now has a time-to-live of twenty - seconds. if only deferred attempts are waiting after that - interval the kernel gets sent ETIMEDOUT. - - * (afs_ops.c) the name by which the kernel knows the filesystem - has changed from pid%d@host to /mountpoint@host. That looks - better to users who get hit by it. - -Fri Jul 14 18:46:16 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) now knows about defered mounts - mounts which - are not in progress, not completed, and not failed. - - * (sched.c) added new entry point sched_ast(). This simulates - a completed job. The basic idea is to let something else return - to the main scheduling loop with a guarentee that it will be - called back when some other action has taken place. - - * (nfs_ops.c) implemented a file handle cache. The nfs_init - routine starts up a request for the filehandle and the mount - routine uses it when it arrives. - -Thu Jul 13 18:07:58 1989 Jan-Simon Pendry (jsp at achilles) - - * (afs_ops.c) found a race condition between an error occuring - and the am_node being timed out. Fixed by updating the - time-to-live and keepalive counters in the node whenever - AMF_MOUNTING is cleared. Also changed afs_lookuppn() so that - it doesn't destroy the node when it returns the error code. - This stops thrashing and the node is eventually timed out. - Now the only way a node gets deleted is by the timeout code - which seems more elegant. - -Tue Jul 11 15:36:44 1989 Jan-Simon Pendry (jsp at achilles) - - * Created "beta15". - - * Fixed *all* references to "u2.2". Some where missed in - the original change. They are now u2_2. - - * (mk-amd-map.c) new command. Converts plain files into - ndbm databases for use by the info_ndbm module. Hooks - included for future support for gdbm just as soon as I - can get a copy. - -Sun Jul 9 19:00:22 1989 Jan-Simon Pendry (jsp at achilles) - - * Created "beta14". - - * (get_info.c) code to handle yp and files now split into - new files info_yp.c and info_file.c New support for ndbm - databases is in info_ndbm.c. A table in get_info.c controls - what and in which order things are searched. - - * (map.c, nfs_stubs.c) better handling for hung mount points. - if a filehandle is passed in by the kernel which references - a hung node, then try to find a replacement, possibly by calling - lookup explicitly. - - * (*.c) use new xlog(level)(message) interface - -Thu Jun 8 20:28:55 1989 Jan-Simon Pendry (jsp at achilles) - - * (nfs_ops.c, ufs_ops.c) when compiled with DEBUG, display - the fs options being used. - - * (am.c) make test for root a little more polite. - - * (get_args.c) update Usage message to include -r option. - -Wed Jun 7 16:28:51 1989 Jan-Simon Pendry (jsp at achilles) - - * (rpc_fwd.c) fwd_reply: if the recvfrom call fails because it - is interrupted then try again. - -Tue Jun 6 16:39:15 1989 Jan-Simon Pendry (jsp at achilles) - - * Created "beta12". - - * (afs_ops.c) inheriting mount option list from command line - is now cumulative. A -foo on the command line is prepended - to the default option list taken from the map. This can be - used to override the ``default default'' options in opts.c. - - * (get_args.c, am.c) added new -r (restart) option. Restart of - mounted filesystems is only done if this option is specified. - [Should *not* be specified in /etc/rc.local of course. - wrong] - - * (yp_master.c) make the enumeration error message more verbose - when debugging is enabled. - - * (rpc_fwd.c) rearranged some declarations at the top. Removed - a spurious call to free which was causing grief on some systems, - but not on Sun's. [This problem was the reason for implementing - the -D mem option.] - - * (opts.c) make sure opt_key and opt_path are set to a zero - length string unless otherwise specified. Previously they - were a source of dangling pointers. - - * (nfs_ops.c) make sure that the allocated nfs_private identifiers - are unique even when some filesystem are being restarted. This mean - starting the basic allocation from 1, not zero. - - * (am.h, get_args.c, util.c) added definition and implmentation of - a simple memory allocation trace (D_MEM). - - * (afs_ops.c) afs_lookuppn: tightened up memory allocation and - delay string copying until last possible moment. - -Mon Jun 5 18:01:18 1989 Jan-Simon Pendry (jsp at achilles) - - * (Makefile.com) diffs: added new rule to generate diffs - between versions. - - * (get_info.c) search_file: added a new dlog() to note when - wildcards are returned. - - * (afs_ops.c) afs_lookuppn: call to init_map specifies efs as - the default ops structure. If the location list only contained - defaults and no real mounts then this previously caused a null - pointer dereference. - - * (map.c) last_used_map: Added new variable. Keeps track of the - last used map, which may be wildly different from first_free_map. - This fixes bugs in several routines in this file. - - * (util.c) mkdirs, rmdirs: Changed directory make/unmake. It is - not possible to quickly determine how many directories need to - be created or deleted, so we try to make as many as possible. - - * (opts.c) Added default values for rfs, rhost and fs. - The new defaults guarentee unique names to allow the NFS - keepalive stuff to work. - -Sun Jun 4 16:12:15 1989 Jan-Simon Pendry (jsp at achilles) - - * First draft of documentation included in the next release. - - * Hooks for TFS added, though this still requires a lot of work. - - * Re-implemented option handling. Options are now allocated - dynamically on a per-mount basis in the continuation structure. - - * Changed os type u2.2 to u2_2 to allow for regular expression - matching in selectors. - - * Format of mount maps is now entirely different. Instead of - guessing which filesystem type is being used, it is now explicitly - stated along with the required options. Variable expansion is - done on the options and selectors are also implemented. The - requested name can also contain any of the selectors. - -Wed May 24 15:21:39 1989 Jan-Simon Pendry (jsp at achilles) - - * Re-implemented NFS ping algorithm to use the new RPC forwarding - system. This allowed a large amount of nfs_ops specific code - to be removed from nfs_start.c and moved to nfs_ops.c. - There is still no strategy for hung file systems. At the moment - it will merely try to mount an alternative (or the same again) - to the same place in the file system. - - * Added RPC forwarding package. This supports general RPC gatewaying - over a UDP transport. The idea is to put a packet identifier into - each outgoing RPC packet and then match that up in a database when - a reply comes in. The database records the original packet identifier - (so that it can be replaced), the source address for the packet and - a function to call to do the forwarding. - - * ChangeLog added between beta8 and beta9. Should have done this sooner. |
