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.

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.

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. |
