*** Notes specific to am-utils version 6.1.2.1 - Bugs fixed: * properly turn off the attrcache in freebsd and openbsd * can turn off attrcache on netbsd, but need kernel patch, see README.attrcache *** Notes specific to am-utils version 6.1.2 MAJOR BUG FIXES: Synchronize Amd's view of its file systems with the kernel's NFS client-side DNLC/dcache. Amd changes its view when it reloads maps (automatically or via "amq -f") because new map entries could be added, old one removed, or existing ones changed. Amd also changes its view when a simple entry has expired and was flushed, or was forced out via "amq -u". Amd was not updating the mtime of its parent directory (often the amd automount point): this resulted in the kernel re-using cached entries, which are now possibly stale. Many users had seen this problem in the form of occasional ESTALE errors, or dangling/broken automounted symlinks, especially on systems under heavy use. To tell the kernel to ignore (flush) its old entries for an directory, the mtime of the directory must be updated (monotonically incremented). Amd was indeed doing so in several places, but unfortunately it was using time(2) which only provides a one-second resolution clock: this was fine a decade ago, but not good enough on today's fast systems; using only a one-second resolution clock meant that on busy systems that invoke Amd many times a second, some rapidly changing entries do not get flushed from the kernel, and the kernel thus uses stale entries. The solution to all of these was to rework the whole clock timer updates to use gettimeofday(), using a micro-second resolution timer, and to use that time whenever Amd needs to update an mtime/atime/ctime of any node. Finally, we now update the mtime in places that were never updated before (when a whole map is flushed or a single entry times out). Warning: some OSs, we discovered, are incapable of turning off their NFS attribute cache entirely. This means that Amd cannot work fully reliability on these systems, not under heavy load. This is documented in detail in the README.attrcache file included with this distribution. - minor new ports: i386-pc-linux-deb3.1 powerpc-apple-darwin8.2.0 - bugs fixed: * minor documentation corrections *** Notes specific to am-utils version 6.1.1 New amd.conf global parameter: forced_unmounts (default to "no"). If set to "yes," and the client OS supports forced or lazy unmounts, then Amd will attempt to use them if it gets any of three serious error conditions when trying to unmount an existing mount point or mount on top of one: EIO, ESTALE, or EBUSY. This could be useful to recover from serious conditions such as hardware failure of mounted disks, or NFS servers which are down permanently, were migrated, or changed their IP address. Only "type:=toplvl" mounts hung with EBUSY are forcibly unmounted using this option: this is useful to ensure that a new Amd can mount itself even if a previous Amd died and left its mount points hung, or to force Amd to shutdown cleanly, even if some processes (i.e., user shells) have their CWD on Amd's own mount point. This functionality is available for Linux, BSD44 systems, Solaris, OSF/1, and partially for AIX. New amd.conf global parameter: truncate_log (default to "no"). If set to "yes", then Amd will truncate the log file (if it's a regular file) on startup. This could be useful when conducting extensive testing on Amd maps (or Amd itself) and you don't want to see log data from a previous run in the same file. - minor new ports: i386-pc-linux-fc4 i386-pc-linux-suse9.3 i386-pc-linuxoldld-deb3.1 - bugs fixed: * safer mtab handling for Linux (locks + handles /proc/mounts) * small compile problems on Solaris 6 (rpcvers_t) * small compile problems on HPUX 10 (h_errno) * possibly missing definition of INADDR_NONE in wire.c * extern for sleep(3) may be missing on older gcc systems * updated nfs_args structure on aix4. * possible running off end of exported_ap[] array. * buffer overflow in pawd. * aix4 clean build. * use strlcat/snprintf in a few places for safety. * recover from IP address change of a down NFS server * don't discard restarted mntfs that was used. *** Notes specific to am-utils version 6.1 - bugs fixed: * set timeo/retrans for type:=nfs only if user asked Also, if you want to know what's new in 6.1 compared to 6.0.x, it's EVERYTHING below this line, up to "6.0.4." Yes, that's a lot of stuff. *** Notes specific to am-utils version 6.1-rc7 Remove alloca from am-utils, and rewrite code that used it. Assorted minor code cleanups. - minor new ports: alpha-unknown-linux-gentoo1.4.16 alphaev56-dec-osf4.0f (using both cc and gcc) mips-sgi-irix6.5 (using both cc and gcc) mips-unknown-linux-gentoo1.4.16 sparc64-unknown-linux-gentoo1.4.16 - bugs fixed: * getwire() detects networks correctly on OSF/1 *** Notes specific to am-utils version 6.1-rc6 - minor new ports: i386-pc-linux-deb3.0 i386-pc-linux-gentoo1.4.16 i386-pc-linux-suse9.2 i386-unknown-freebsd5.4 i386-unknown-netbsdelf2.0.2 i386-unknown-openbsd3.7 powerpc-unknown-linux-yellowdog2.3 - bugs fixed: * minor compile error of nfs_subr.c on some systems. * AIX 5.2/5.3 PPC compile fixes. *** Notes specific to am-utils version 6.1-rc5 For NetBSD systems, $os used to say "netbsdelf1" or "netbsdelf2." Now it just says "netbsd." - minor new ports: powerpc-apple-darwin7.9.0 - bugs fixed: * silly (but nasty) null pointer dereferencing * improved fix for '-opts' syntax for resetting map options *** Notes specific to am-utils version 6.1-rc4 - bugs fixed: * check for "macosx" in M4 macros properly * minor memory leaks (thanks to Valgrind) *** Notes specific to am-utils version 6.1-rc3 Minor fix to configure.in. Reran bootstrap to get a working configure script that indeed checks for certain Linux nfs/autofs headers. *** Notes specific to am-utils version 6.1-rc2 New amd.conf global parameter: normalize_slashes (default to "yes"). If set to "no," then Amd will not condense repeated slashes or remove trailing ones from strings representing pathnames. This is sometimes useful with SMB mounts, which often require multiple slash characters in pathnames. Using a custom version of strlcpy instead of strncpy (but only where it makes sense), to minimize string overflow changes. Audited all use of strncpy/strlcpy to ensure safety. On Apple machines, use "powerpc" for $arch, instead of "Power Macintosh". Also, use sw_vers to find out more appropriate OS name (macosx) and OS version (10.3.x) than uname(3) reports. - minor new ports: powerpc64-unknown-linux-rhel4 powerpc64-unknown-linux-sles9 - bugs fixed: * pawd handles all file systems * fix double-free in type:=nfsx * timeo and retrans shouldn't be set for type:=toplvl * fix inconsistency in handling filehandle generation number * document proper use of hosts.allow (don't spawn) * single dash '-' map entry now resets the defaults *** Notes specific to am-utils version 6.1-rc1 - minor new ports: i386-pc-linux-fc2 (Fedora Core 2). i386-pc-linux-fc3 (Fedora Core 3). i386-pc-linux-rhel3 i386-pc-linux-rhel4 i386-pc-linux-suse8.2 i386-pc-linux-suse9.1 i386-pc-solaris2.10 i386-unknown-freebsd4.8 i386-unknown-freebsd4.9 i386-unknown-freebsd4.10 i386-unknown-freebsd4.11 i386-unknown-freebsd5.1 (5.1-RELEASE) i386-unknown-freebsd5.2 (5.2-RELEASE) i386-unknown-freebsd5.2.1 (5.2.1-RELEASE) i386-unknown-freebsd5.3 (5.3-RELEASE) i386-unknown-freebsd6.0 (6.0-CURRENT-SNAP001) i386-unknown-netbsdelf1.6.1 i386-unknown-netbsdelf2.0 i386-unknown-openbsd3.6 ia64-hp-hpux11.20 ia64-unknown-linux-rhel4 mipsel-unknown-linux-rhPS2 (Linux on Sony PlayStation 2) powerpc-apple-darwin7.6.0 powerpc-apple-darwin7.7.0 powerpc-apple-darwin7.8.0 powerpc-ibm-aix5.2.0.0 powerpc-ibm-aix5.3.0.0 sparc-sun-solaris2.10 sparc64-unknown-linux-deb3.0 x86_64-unknown-linux-rh2.9.5AS - support for executable maps ala Sun automounter. Set map_type=exec in amd.conf, and map_name to a program/script that takes a key as argv[1], and returns key-value pair on stdout. See also exec_map_timeout [global] parameter which defines how many seconds (default 10 sec) Amd will wait for an executable map program to return output before timing out. See am-utils manual for full details. - new amd.conf parameter "nfs_allow_insecure_port". Used to work around bugs in certain kernels, which cause them to try and talk to amd from unprivileged ports. - new amd.conf parameter: localhost_address. Used to override the localhost (often 127.0.0.1) address Amd uses to connect to for the local NFS server and RPC server. - new amd.conf [global] parameter: domain_strip (default "yes"). If set to "no," Amd won't strip domain names from host names, which is useful if your Amd maps are served by multiple domains and you want to tell from the logs which exact host did what. - new amd.conf [global] parameter: auto_attrcache (default to 0). Sets Amd's own NFS attribute-cache timeout in seconds. A value of 0 turns off attribute caching, meaning that Amd will be consulted via a kernel-RPC each time someone stat's the mount point (which could be abused as a denial-of-service attack). If you're concerned, set this to something greater than zero (a value of 1 second is currently recommended). Warning: if you set this option to any non-zero value, especially a large value, and you get ESTALE errors on your particular OS, then set this value back to 0 seconds. - four new amd.conf [global] parameters, similar to nfs_retry_interval and nfs_retransmit_counter, which allow you to set the "timeo" and "retrans" NFS mount parameters, respectively. Now you can set those parameters globally and separately for UDP vs. TCP, using any of these: nfs_retry_interval_udp, nfs_retransmit_counter_udp nfs_retry_interval_tcp, and nfs_retransmit_counter_tcp. - new amd.conf [global] parameter: preferred_amq_port. Allows you to select the UDP+TCP port that Amd's amq service will use with the RPC portmapper. Useful with firewalls and NAT'ed environments. - new amd.conf option "debug_mtab_file". Allows user to define the mtab file during debug-mtab mode. The default path is "/tmp/mnttab". - new function selector xhost(ARG) which will match ARG against the current host name. This works even if ARG is a CNAME (unlike the host==ARG selector). - support restarting the automounter's own mount points (only over NFS, for now). - fully support WebNFS as per RFC 2054. It now tries v3/TCP first, falling back to v2/UDP if this doesn't work. The "webnfs" pseudo-mount options has been renamed (again) to "public" to match Solaris 2. - restructured the restarting of already-mounted filesystems, in the process also fixing a problem with restarting nfsx components. - support escaped slashes, needed for SMB mounts. Use '\\\/\\\/' in a string to get a double slash. - amd -v now prints domain, host, and hostd values: foo, example.com, and foo.example.com, respectively. - On Linux, if umount(2) failed with EIO or ESTALE, try the new umount2(2) system call with MNT_FORCE+MNT_DETACH. This could be quite helpful to unmounting hung mount points that otherwise cannot be fixed without a reboot. - The ping=N mount option now works. N defaults to 30 seconds for all NFS servers. It can now be set to any value for each server separately. Setting it to a large value can reduce the amount of NFS_NULL chatter on your network considerably, especially in large sites. Setting this to -1 will turn off pings for that server (useful in NFS-HA setups). Setting N to 0 will pick the default ping value in Amd (currently 30 seconds). Note that if you have multiple Amd entries using the same file server, and each entry sets a different value of N, then each time Amd mounts a new entry, the ping value will be re-evaluated (and updated, turned off, or turned back on as needed). Note that NFS_NULL pings are sent for both UDP and TCP mounts, because even a hung TCP mount can cause user processes to hang. - file system inheritance code restructured, so it's no longer a pseudo file system, but actually integrated into Amd (as it should have been). - for type:=program, the "umount" program doesn't have to be defined; it'll default to "unmount ${fs}". - "amd -v" now prints the distribution name if it's known (e.g., rh9, fc3, suse8, etc.). - bugs fixed: * various memory management problems (leaks, etc) * fixed nfsx support * fixed a race involving late replies to network queries which arrive after the file system has already been mounted * recognize pcfs_args_t fields in FreeBSD 5 * recognize other mount types in pawd: host, linkx, and nfsx * allow exactly one of umount and unmount in type:=program * race condition between calls to mntctl() on AIX * plock/mlockall wasn't inherited by fork(); moved after daemonizing. * fix inconsistency between Socket and TLI RPC timeouts. * don't warn when couldn't rmdir a dir with a readonly ancestor. * avoid hangs of amd in ctl-amd (must chdir to /) * workaround occasional daemonizing problems (parent won't die) * don't hang on exit if debug_options=mtab was used * utimeout=N mount option works with non-nfs types (ufs, pcfs, etc.) * SEGV (null pointer deref) in type:=program and type:=cachefs * unmount_on_exit of type:=program caused amd to hang * match amd2ldif output with ldap.schema *** Notes specific to am-utils version 6.1b4 - minor new ports: i686-apple-darwin6.6 - speed up the recovery of inherited (restarted) filesystems by using the proper waiting channels - added support for mounting webnfs filesystems, see entry below. It doesn't do any probing currently, so it will default to v2/UDP unless another version and/or protocol are explicitly specified. - pseudo-mount option "ignore_portmapper" renamed to "webnfs" - bugs fixed: * properly time out autofs filesystems on Linux * link mounts with relative targets weren't working on autofs * the link side of the nfsl file system wasn't working on autofs * umount code was accidentally turning all symlinks into directories during attempted umounts, causing stale filehandles * various minor build fixes for "impossible" configurations * prevent ldap code from dereferencing a null pointer *** Notes specific to am-utils version 6.1b3 - new amd.conf option autofs_use_lofs, set by default to "yes". "yes" means using in-place mounts (lofs, bind mounts, etc.), thus utilizing one of Autofs's main advantages. "no" means using symlinks instead, which has the "/bin/pwd" problem and certain efficiency issues on Solaris 2.6+ and is also not supported on Solaris Autofs v1 and derivatives; however, the autofs code that uses symlinks is simpler and more thoroughly tested. - new amd.conf option map_default (can be used in [global] and overwritten in the per-map section). This will overwrite the /defaults entry of the map itself, to allow people to set defaults in amd.conf (useful when you cannot control your amd maps, or you'd rather not modify them globally). - for type:=program, you can use either unmount:=XXX or umount:=XXX (but not both). This new 'unmount' name is an alias for convenience. - fixed the "multiple matching sub-entries in a map entry" semantics to try mounting those sub-entries one by one, until either one succeeds or all fail. The old semantics of trying to mount everything in parallel and use the one that mounted fastest hasn't worked in a long time; in fact, 6.0 currently simply ignores all but the first matching sub-entry. - made amd fail much faster (instantly, in fact) if the remote server doesn't have a functional portmapper or NFS service. Also reduced the total timeout to 3 seconds for a completely downed server. - new pseudo-mount option "ignore_portmapper"; not very useful currently, will make more sense when we also accept hard-coded ports for mountd and nfsd. - amd will no longer query the portmapper for all possible NFS versions and protocols if the user requested to use specific ones. - increased the major number for the library, so that 6.0 and 6.1 can't share libraries anymore. - support tcpd/libwrap tcpwrappers. If your system supports libwrap, then you can use /etc/hosts.allow and /etc/hosts.deny to control remote Amq access to Amd. The new amd.conf parameter use_tcpwrappers is set to "yes" by default. - support NULL entries in Hesiod maps, if they start with a ".". - code reorganization - documentation cleanup, corrections, and general updates. Better references to all man pages. Support newer texi2html. Proper building of DVI and PSI files. Allow building of am-utils manual in one long Web page. - minor new ports: ia64-unknown-linux-rh2.1AS (Red Hat Itanium Advanced Server) i386-unknown-freebsd5.0 (5.0-RELEASE) sparc64-unknown-linux-suse7.3 i386-unknown-netbsdelf1.6.1 i386-unknown-openbsd3.3 i386-pc-solaris2.9 - bugs fixed: * autofs mode on Linux was segfaulting on a silly error (and noone complained, which proves that I'm probably the only one testing these beta releases, tsk tsk). * fixed handling of host entries over autofs. * fixed handling of nfsl entries over autofs. * the matching in find_mntfs() was causing problems for inherited filesystems, so make an exception for them. Tighten the matching even more, to take into account the f/s type as well. * recognize xlatecookie mnttab option on netbsd * document Solaris lex bug (use flex) * document AIX 5.x NFS bug (need patch) * document Solaris 8 autofs version change (need to fix system header file) * ensure lex doesn't run out of output slots * support GNU flex-2.5.31+ * force version.texi to be rebuilt unconditionally * mk-amd-map open db file exclusively (security) * turn off maintainer-only rules in distros * don't core dump if log_file is NULL (Solaris) * don't include malloc.h if stdlib.h exists * recognize file system failures (EIO) upon reading file maps *** Notes specific to am-utils version 6.1b2 - new mount flag "softlookup", which determines how amd will respond to lookups of NFS shares already mounted (return a valid symlink or return EIO). The default, if "softlookup" is not specified, depends on whether the mount is "soft" or "hard". - return EIO instead of ENOENT if amd thinks the server is down; this allows well-written applications to sleep and retry the operation. - minor new ports: i386-apple-darwin6.0 i386-pc-linux-rh8.0 ia64-unknown-linux-rh2.1AW sparc-sun-solaris2.9 - automatic support for loop mounts on Linux (deprecates the "loop" mount option) - new amd.conf parameter ldap_proto_version (default 2) for setting the LDAP protocol version to use. - bugs fixed: * redundancy mode (multiple servers for the same share) wasn't working * non-autofs mode had some rather nasty hangs on downed file servers * double-free'ing problem in assign_error_mntfs and free_continuation * free'ing non-malloc'ed memory in amfs_auto_mount * late server ping replies were not ignored * amfs_auto_lookup_mntfs wasn't propagating errors up to callers * autofs-v4 on Solaris 9 works * handle std{in,out,err} correctly when releasing controlling tty (for real this time) * don't cast pointers between enum_t and u_long, it doesn't work on 64-bit big-endian platforms * fix compile problem with mlockall() on Darwin *** Notes specific to am-utils version 6.1b1 - Major Autofs work Partial support for Sun Autofs v1 Documented known problems with Sun Autofs v1 (possible deadlocks) Fixes for Sun Autofs v2/v3 Preliminary support for Sun Autofs v4 (Solaris 9) Kernel-based expirations for Linux Autofs - Minor new ports: powerpc-ibm-aix5.1.0.0 i386-unknown-netbsd1.6A - Work around IBM's NFSv3 ABI change in aix4.3 - trivial regression test suite started: run "make check" on a built am-utils to execute tests. Currently only one test which checks to see if "amd -v" executes correctly. - new command line option "amd -A arch" to overwrite the value of $arch. - bugs fixed: * Linux loop mounts of ISO images * assorted LDAP fixes * strerror not found on some systems * small fixes for hpux9 and aix43 * exclude ldap/hesiod support unless both libraries+headers exist * fully support "xlatecookie" mount option * security: if -D noamq option, don't listen on socket. *** Notes specific to am-utils version 6.1a5: - browsable_dirs support for Solaris autofs, *without* mount storms! - new amd.conf global parameter: map_reload_interval (default 1 hour). Determines how often Amd checks to see if maps have changed at the source (and then reloading only those that have changed). - "amd -v" now lists bug-reporting address. - assorted code cleanups and porting to use latest versions of GNU Autotools. - opts:=loop works for type:=cdfs, for mounting ISO-9660 files on Linux. - bugs fixed: * fixed sublink support in Linux autofs (broken in a4) * hlfsd takes uid 0's home from root's passwd entry instead of defaulting to '/' * (not really our bug) Linux ignores the microseconds field in mtime, so hlfsd and amd need to increment the seconds field all the time to prevent symlink caching * generic map parsing bug which was rejecting a numerical mount option if it was the last option in the string. * file descriptor leak in Linux autofs. * "nolock" is an NFS mount option, not a generic one. * use mlockall(2) on systems that have it, for plock=yes. Now pinning Amd's pages in memory works on Linux. * ctl-amd/ctl-hlfsd correctly refer to @sysconfdir@ for alternate location of configuration files. *** Notes specific to am-utils version 6.1a4: - full autofs support for Solaris 2.[67], including symlinks, sublinks and direct mounts - fixed mount/umount deadlock in Linux autofs - fixed sublinks in Linux autofs - support for network/netmask pairs in the in_network() selector - support disabling LDAP and Hesiod support using configure - forward-ported all the fixes from the stable branch (MacOS X support, minor Linux fixes) - bind-mount support for type==link and type==lofs with Linux 2.4+ - FiST lofs support under Linux (also in 6.0.6s2) *** Notes specific to am-utils version 6.1a3: - various things from the 6.0 branch: compile fixes for Linux 2.4-ac and 2.2.19pre+ Darwin/Rhapsody/OS X support much reduced configure script (works around a bug in Darwin's cpp) *** Notes specific to am-utils version 6.1a2: - working autofs support for Solaris 2.[67], but incomplete - forward-ported all the changes up to 6.0.5s2 - removed support for amq -M - known bugs nfsx support is broken linux NFS codes fixes NFS cache aliasing fixes lots of stuff ported from 6.0 branch *** Notes specific to am-utils version 6.1a1: - working autofs (v3 and v4) support for Linux! - forward-ported all the changes in 6.0.4s4 - bugs fixed client-side fail-over to NFSv2/UDP - known bugs autofs v3 will probably break with host maps *** Notes specific to am-utils version 6.0.4: - NFSv3 support for Linux and HPUX-11 - new amd.conf [global] options: nfs_vers: force all NFS mounts to version 2 or 3 nfs_proto: force all NFS mounts to udp or tcp - new debug_options (amd -D): hrtime: turns on high-resolution timer if available readdir: traces browsable_dirs code xdrtrace: traces XDR routines (trace: only traces NFS and RPC) - new amq options: -H: shows usage -w: translate getpwd() into an Amd path - new map syntax: ${dollar}: to include a literal '$' in assignments - new "opts:=" options: ver3: turns on NFS version 3 on some systems (linux) - updated or minor new ports: alpha-dec-osf4.0f alphaev6-dec-osf5.0 i386-pc-linux-rh6.2 i386-unknown-freebsd3.4 - bugs fixed: symlink mtime fixes to avoid u/mount race conditions update amq -s failed umounts count correctly linux compiles even if efs is available linux works with mount(2) option "intr" linux works with pcfs and cdfs handle std{in,out,err} correctly when releasing controlling tty browsable_readdir works on 64-bit kernel architectures irs/wire routines compile for bsdi{2,3,4} *** Notes specific to am-utils version 6.0.3: - updated or minor new ports: hppa1.0-hp-hpux11.00 i386-pc-bsdi4.1 i386-unknown-netbsd1.4.1 sparc-sun-solaris2.8 i*86-pc-linux-gnu-rh6.1 (some preparations for Compaq Tru64) - new variables ${uid} and ${gid}, return the numeric UID/GID of the user (not root) who invokes an amd pathname. Similar to what hlfsd does. - automake now uses automatic dependency tracking - new mount options: optionstr, noexec, nomnttab - maps of type:=auto are now browsable (using map option "browsable") - ctl-amd has "status" argument (same as RedHat) - bugs fixed: document buggy AIX 4.3 plock() behavior fixes to stale file handle on symlinks reduce race conditions upon rapid umount/mount sequences use vsnprintf, more secure than vsprintf more assorted and smaller bugs *** Notes specific to am-utils version 6.0.2: - safe map reloads: when a map needs to be reloaded, it is reloaded into a temporary copy first. Only if the reload was completely successful, Amd discards the old map and uses the new one. Otherwise Amd continues to use the old maps. This should help a lot with transient NIS problems. - amq -f now also forces a (safe) map reload, but only if the timestamp on the maps was updated. - two new selector variables: ${vendor} and ${full_os}, which are the same as the output seen in "amd -v". - documentation fixes and updates - updated or minor new ports: i386-unknown-freebsdelf3.3 - support 'ignore' flags (automntfs) in bsdi-4.1 - bugs fixed: expn.pl uses correct sockaddr_in() not, pack() make sure configure --enable-*args take an argument don't busy-loop trying to rebind to ldap servers use vsnprintf, not vsprintf (security) *** Notes specific to am-utils version 6.0.1: - updated or minor new ports: i386-pc-bsdi4.0.1 i386-unknown-freebsdelf3.0 i386-unknown-freebsdelf3.1 i386-unknown-freebsdelf3.2 i386-unknown-freebsdelf4.0 i386-unknown-netbsd1.4 i386-unknown-openbsd2.5 powerpc-unknown-linux-gnu - automount2amd added, a new script to convert Sun automount maps to Amd maps - new map function netgrpd(ARG), same as netgrp() but matches FQHN - 'ignore' is a generic mount option - hesiod info service isup() function to check if service is up - more Y2K fixes (see README.y2k for the full story) - using alloca.c on systems that don't have it (hpux9 with /bin/cc) - configure script reduced in size by using M4/sh loops instead of repeated entries - documentation updates - too many bugs fixed to list here: 'addopts' option works with 'remopts' as well as 'opts' AIX can perform NFS V.3 mounts explicitly NIS is_up fixed, especially for NIS+ running in compatibility mode amd -v incorrectly listing file systems that don't really work amd's own mounts use reserved ports if possible browsable directories works for Linux 2.3 (NFS cookies) bsd44 systems check for isofs flags bsd44 systems check for new options: norrio, gens, and extatt buildall works better on Ultrix's /bin/sh compile and build on Linux kernels 2.2 and newer compile and build on RedHat Linux 6.0 (glibc 2.1) compile and build on Solaris 7 (with or without vendor LDAP) completely eliminate all of amd's amq -M code, when not enabled correctly interpret failure code of unmount of type:=program don't create autofs listener service unless used don't list or process amq's -M option unless feature was turned on don't turn on/off noconn option if it was already in that state ldap info service: don't strcmp null strings lostaltmail correctly sets struct sockaddr_in make sure Linux systems have configured kernel headers test for bsize/namlen fields in nfs_args (linux mount versions 2/3) turn off broken NFS V.3 support for HPUX use getifaddrs() on bsd44 systems makes wire.c more reliable use matching NFS rsize/wsize on Linux 2.0 and 2.[123] kernels. verify that RPC requests come from reserved, privileged local ports warn when Linux kernel headers mismatch with running kernel pawd works for type:=nfsl too *** Notes specific to am-utils version 6.0: - updated or minor new ports: hppa2.0w-hp-hpux11.00, i386-pc-bsdi4.0 i386-unknown-freebsd2.2.8 i386-unknown-netbsd1.3.3 i386-unknown-openbsd2.4 mips-sgi-irix6.5 powerpc-ibm-aix4.3.1.0 i386-unknown-freebsd3.0 now supports nfs v.3 - ctl-amd and ctl-hlfsd now compatible with RedHat's chkconfig utility - ctl-amd stop will now wait until amd is down - libamu.so completely self contained --- does not export any symbols which must be defined by the process linking with it. This is so shared libraries could be supported on systems that have restrictive shared libraries. - use latest autoconf, automake, and libtool (off of cygnus' CVS server) to support shared libraries on many more platforms. - posix code cleanups - bugs fixed: case insensitive host match in type:=nfsl correct swapped args to kill(2) try to avoid a race condition b/t mounting and unmounting yp_all support is found in libnsl in RH-5.1 systems *** Notes specific to am-utils version 6.0b1: - updated or minor new ports: - *-pc-linux-gnu (glibc2 systems such as RedHat 5.1) - sparc-sun-solaris2.7 - i386-pc-solaris2.7 - i386-unknown-freebsd3.0 (official release, post 4.4lite port) - sparc64-unknown-linux-gnu (RH 5.1 on Sun Sparc Ultra) - bugs fixed: - major memory leak in processing of /defaults - core dump if map_type given in amd.conf doesn't exist - memory leak in replacement yp_all - don't access uninitialized memory in DU 4.0 - other smaller bugs, see ChangeLog *** Notes specific to am-utils version 6.0a16: - new ports: hppa1.0-hp-hpux11.00 (works, not NFS V.3 due to missing headers) mips-dec-ultrix4.3 (working, unverified) - new minor ports: i386-pc-bsdi3.1 i386-unknown-netbsd1.3.1 alpha-dec-osf2.1 - new options addopt:=ARG will "smartly" add and override options specified in opts:= - new amd.conf options: pid_file: specifies the file to store the PID hesiod_base: specifies the base for the Hesiod service unmount_on_exit: if 'yes' will attempt to unmount all file systems when amd exits. - amd.conf file is parsed after all other command line options. If no options specified at all, then use /etc/amd.conf by default. - some variables' values are now compared case-insensitive as per specs, such as host names, domain names, and more. - NIS service uses a new isup() function to detect if the service is up before using it. Used to ensure amd doesn't clear the existing maps before reloading them, unless the remote info service is working. - new cdfs mount options: rrip, noversion, defperm, nodefperm (OSF) - support efs/xfs separately on irix - new -D info trace option to turn on info specific debugging, such as RES_DEBUG for hesiod services. - document updates and fixes - new file MIRRORS lists official mirror sites (also in am-utils home page) - new file BUGS lists known amd/OS bugs - source restructuring: rename all Amd file-systems' sources to amfs_ARG.c such that it matches the type:=ARG as well. Free names afs/dfs for Andrew F/S and Distributed F/S. - checkpoint config.guess several times during the long configure, so that if it is aborted midway, the bulk of the features discovered will be re-read from the config.cache file. - more systems support shared libraries (libtool 1.2) - using automake 1.3 + more fixes - bugs fixed: use dynamic buffer for list of interfaces, not fixed size output of amd -H duplicated if >2 interfaces -D mem for hlfsd not on by default (so it will daemonize) linux looks for ext2fs before ufs CDFS looks for 'isofs' mount type as well compile on Solaris 2.6 with /opt/SUNWspro/bin/cc various additional fixes which gcc 2.8.x reported print syslog help string based on what's supported correctly ignore loopback interface on SunOS 3.x don't use -lucb for strcasecmp hlfsd's dump file securely written in /usr/tmp/hlfsd.dump.XXXXXX inherit NFS V.3 mounts correctly write pid file securely *** Notes specific to am-utils version 6.0a15: - new ports: alpha-unknown-linux-gnu: works i386-unknown-netbsd1.3: fully working *-sun-sunos3: compiles, not tested - updated ports: m68k-next-nextstep3: cleaner compile, works. - new file system type nfsl (NFS Link). Uses nfs if file system is remote, and link if it is local (based on if $rhost equals the host name). - support for Solaris cachefs. Requires setting fs, rfs, and a new variable cachedir. See documentation for explanation, examples, and caveats. - support negated selector functions such as !exists(/foo/bar) - wire, network, netnumber, in_network() selectors now match against all locally attached networks (by either name or number), not just the first two interfaces. - new program pawd (and man page for it) --- Print Automounter Working Directory, to print the proper pathname of the cwd or any other pathname, adjusted for automounter paths, while avoiding mount points. - two new switches to amq: -U will force using UDP only; -T will force using only TCP to communicate with amd. If neither (or both) are specified, amq will try TCP first, and if that failed, will try UDP. - support syslog facilities, using "amd -l syslog:facility". Old behavior when using only -l syslog is to use the LOG_DAEMON facility. - you may specify browsable_dirs=full, to get a listing of all entries (other than /default), including those with '*' wildcard and '/' characters. - amd -D trace now also includes as much of struct nfs_args as can be displayed. Useful in figuring out what the kernel really gets during a mount(2), as opposed to what the /etc/mnttab file says. -D trace also traces the xdr_* functions. - support for versions of shared libamu version. upped version from 0.0.0 to 1.0.0. each am-utils release that will change the library will also update its version. - amd/ops_TEMPLATE.c: a new template file for those brave enough to try and implement a new amd file system. Includes comments and other info useful for developers. - if localconfig.h exists in the current directory during the run of configure, it is included in all am-utils sources. This allows courageous developers to make certain modifications during compilations, and especially turn off undesired features (not very recommended). - documentation types and updates for all new features, ports, etc. - bugs fixed: support NFS mount options grpid and maxgrps nextstep: set NFS success code to 0 (NFS_OK), not 1 (EPERM) bsdi2: set NFS success code to 0 (NFS_OK), not 1 (EPERM) set NFS V.3 mount table names to "nfs" if vers/proto exist use mkstemp() if possible (more secure) ctl-amd looks for amd.conf in ${prefix}/etc after /etc hpux: use "ignore" mount table type openbsd2.2: turn off "noconn" mount option, so only connected used fixed memory leak in hlfsd (don't setpwent after endpwent) all NFS3 systems should have proto/vers mount/amd options DEBUG_MEM compiles and prints something more useful uninit_mntfs(): free() mf_private *after* it is used browsable_readdir: fewer bytes sent back to kernel for each chunk mount_toplvl: don't free() an automatic variable! amd should chdir() to / before daemonzing (for core dumps etc) cdfs should be called 'cdfs' not whatever the mnttab type is amd -v: don't print "FS:" list twice when >=2 net interfaces *** Notes specific to am-utils version 6.0a14: - updated ports: powerpc-ibm-aix4.2.1.0: NFS V.3 works - minor new ports: sparc-sun-sunos4.1.3C m68k-sun-sunos4.1.1 (sun3) mips-sgi-irix5.2 - new option to amd, -O ARG, will override the operating systems *name* with ARG. Corrected documentation for amd -o ARG --- it overrides the operating system *version* and not the name as the docs incorrectly stated. - logging now behave more like syslog: will not print repeated strings, but rather a count such as "last message repeated N times". (N will not exceed 100.) - restructured the code which deals with the numerous possible fields and flags that are set in struct nfs_args. That code was moved to libamu as the functions compute_nfs_args() and compute_automounter_nfs_args(). - bugs fixed: mnttab name ufs/cdfs/pcfs/etc filesystems corrected use pmap_ping for amq (a must for secure portmappers, bsdi2/3) test for xfs (irix) as a disk-based file system set correct nfs_prot headers for Solaris 2.5 removed stale code from lostaltmail.in lostaltmail will look for conf file in multiple locations assorted documentation corrections amq does not print "get_secure_amd_client" if run as root *** Notes specific to am-utils version 6.0a13: - new in_network(ARG) nomadic selector, true if ARG is the name (or number) of any of this host's network interfaces. - removed variables primnetname, primnetnum, subsnetname, and subsnetnum. (Kept "wire" and its alias "network", and "netnumber".) - include am-utils.dvi and am-utils.ps in distribution. - hlfsd supports new option -P ARG, for reading password map off of file ARG. Allows you to use the hlfs redirector using paths other than user's home directories. - use a replacement yp_all for some systems (irix) known to have a broken one which leaks a file descriptor each time called. - if remote NFS server is down or does not support portmap, downgrade machine to NFS V.2 and retry again later. - bugs: don't redefine yywrap on systems using a modified flex use correct "ignore" mnttab/mount option on hpux for df(1) use nfs_args' fsname field (hpux) to avoid syncer/mount(1) problems don't add ops_ufs.o twice to Makefile's $(OBJS) don't fail if autofs listener fails to initialize hlfsd should test if run as root after usage() and getopt - minor code cleanups for netbsd - html docs now in http://www.am-utils.org - added README file in binaries ftp directory *** Notes specific to am-utils version 6.0a12: - minor or updated/broken ports fixed: hppa1.1-hp-hpux10.10: compiles, untested (probably works). hppa1.1-hp-hpux9.05: compiles, untested (probably works). hppa1.1-hp-hpux9.07: compiles, untested (probably works). m68k-hp-hpux9.00: compiles, untested (probably works). rs6000-ibm-aix4.1.4.0: compiles, untested. sparc-sun-solaris2.6: works w/ NFS V.3. sparc-sun-sunos4.1.4: compiles, untested (probably works). - new ports: powerpc-ibm-aix4.2.1.0: compiles w/ NFS V.3, untested. - wire-test also checks for combinations of NFS protocol/version from the client to a remote (or local) host. - conf/mtab/mtab_file.c: use flock() to lock the file, and fcntl() if flock() is not available. (Used to prefer fcntl() over flock().) - bug fixes: tli get_nfs_version() gets into an infinite loop tli get_nfs_version() should time out faster sockets get_nfs_version() should work w/ secure portmappers ESTALE returned for NFS mounts for SunOS 4.x fixed do not exceed HOSTNAMESZ for nfs_args.hostname (get ENAMETOOLONG) properly initialize some mntent_t fields (fsck, freq, mnt_time) properly initialize some pcfs_args fields (mask, uid, gid) properly initialize some cdfs_args fields (ssector) *** Notes specific to am-utils version 6.0a11: - bug fixes: amd could not NFS mount v.2 servers from v.3 clients hlfsd will only use first occurrence of home dir for same uid *** Notes specific to am-utils version 6.0a10: - MAJOR DOCUMENTATION UPDATE! (first time in 6 years) - new ports: m68k-next-nextstep3: configures, compiles, not tested. - preliminary autofs support. See README.autofs for details. - new amd.conf [global] yes/no keywords: show_statfs_entries: shows number of entries for df(1) fully_qualified_hosts: use FQHN for NFS/RPC authentication - detect down remote hosts faster - log output of "amd -v" at startup - removed $osver override for solaris: now it is 2.5.1, not 5.5.1 - buildall will use gmake first if available - bugs fixed: amd core dumped when remote host was down allow up to 1024 entries back from readdir() amd.conf works even if only [global] option defined avoid using bad memcmp() implementations fixed meaning of plock [global] option (was reversed) hlfsd infinite loop unless compiled with --enable-debug NIS code works with NIS+ servers in NIS compatibility mode reset tag fields in amd.conf so they don't carry to other entries *** Notes specific to am-utils version 6.0a9: - new ports: sparc-sun-solaris2.4: configures/compiles, and runs (no NFS V3) i386-unknown-openbsd2.1: configures/compiles, runs (NFS V3) - updated ports: i486-ncr-sysv4.3.03: configures/compiles, not tested - Multiple amd support: new amd.conf [global] key "portmap_program" can be used to specify an alternate RPC program number for amd to un/register. Allowed numbers range from 300019 to 300029. A matching new option for amq: -P prognum, will use an alternate program number to contact. - man pages: amd.conf.5 new mk-amd-map.8 new amd.8 updated amq.8 updated (other man pages required minor updates) - shared libraries support expanded. Using GNU libtool-1.0. You can build a shared version of libamu, and link with it accordingly, by specifying --enable-shared to configure. Default is --enable-static --disable-shared, and you can mix and match. See "INSTALL" file for listing of systems on which shared libraries seem to build and work fine. - new option: amq -p, will return the PID of the running amd (local or remote). Uses a new RPC message. Useful especially in "ctl-amd stop". - new configure script options --enable-ldflags, for specifying -L flags. The older --enable-libs is to be used only for -l options. - two new LDAP map options for amd.conf: ldap_cache_seconds and ldap_cache_maxmem. - new script, am-eject from Debian linux's version of amd-upl102. - additional passwd map support using var[0-3], from Debian folks. - hesiod code cleanup. works for hesiod 1.3 as well as 3.0. - removed defunct -h option from amd. - started using automake-1.2. This fixed several bugs that caused some versions of yacc/lex and non-GNU make to fail. - bug fixes: amd/hlfsd mounts should be hidden from df(1) use "noconn" option for nfs mounts (multi-homed hosts) don't use connected sockets on linux before 1.3.10 (from Debian) better checks for [gn]dbm forbid excessive retries after timeouts (from Debian) readdir(): don't skip over map entries with prefix, and include it more assorted linux fixes from Debian folks lofs mount on svr4 was broken find default value of $karch from uname() not $arch hlfsd failed to mount itself on some little-endians *** Notes specific to am-utils version 6.0a8: - new ports: i386-unknown-netbsd1.2.1: configures/compiles (with NFS V.3), works, but some OS stability problems exist. - updated ports: hppa1.1-hp-hpux9.01: now tested and working rs6000-ibm-aix3.2 and rs6000-ibm-aix3.2.5: now tested and working - fixed browsable directories (readdir) code. - better methods to find amd/hlfsd pid to kill in ctl-{amd,hlfsd} - "ignore/auto" mount types fixed for irix, sunos, and others, so "df" does not show amd mounts by default (but GNU df -a does). - each time amd is built, a new "build" version is incremented. See amd -v. - man page for fsinfo added - empty fillers for new file (bsd44) systems: nullfs, unionfs, umapfs. - when amd is not running, or portmapper is down, make amq timeout faster (5 sec) than system default, usually 4-5 minutes. - bug fixes: hlfsd mount got "protocol not supported" first regular map in amd.conf didn't inherit global options make "bad" versions of lex still work with amd/conf_parse.l check for 'nodev' option, not 'nondev' typo in "ro" option, and fillers to ac{reg,dir}{min,max} and others amd.conf parsing done before switching default log/debug options allow doubly-quoted values in amd.conf hesiod-reload code cleanup - assorted code cleanup *** Notes specific to am-utils version 6.0a7: - new ports: i386-unknown-freebsd3.0: fully functional with NFS V.3 sparc-sun-solaris2.3: fully functional (should work for 2.4) sparc-unknown-netbsd1.2E: configures/compiles (with NFS V.3), untested - updated ports: i386-pc-bsdi3.0: NFS V.3 works look for hesiod in libc mips-sgi-irix5.3: fully functional with NFS V.3 - LDAP support! New [global] amd.conf options ldap_base and ldap_hostports. Also includes a new script amd2ldif to convert amd maps into plain text LDAP object files. - the following amd.conf variables: browsable_dirs, map_options, map_type, mount_type, and search_path --- can now be specified in [global] as well as the map entry itself. That way you can declare them only once in [global], and override them as needed per map. - option "cluster" added to [global] (HPUX clusters ala "amd -C"). - assorted info_hesiod map fixes and cleanup. removed HESIOD_RELOAD code. - added netgrp(name) function to amd map syntax to see if current host is in the netgroup. - removed unused option "amd -m". - filled in "tasks" file with todo items. - filled "COPYING" file with legal stuff. - cleanup: all global variables are now in one big structure (struct amu_global_options) that's easy to identify and enhance. Also migrated several flags that used be an integer each into one unsigned integer that's used as a bit-flag. - big fixes: xdr_mountres3 should compile only if has NFS V3 lex/yacc macros show full pathname (to tell if correct one runs) misc fixes/cleanup *** Notes specific to am-utils version 6.0a6: - amd configuration file! See scripts/amd.conf-sample for help and some explanation. This new conf file allows for the following new features: default selectors can be turned on/off globally. browsable_dirs/readdir() support can be turned on per map. search paths for file type maps. can force the map type to file, nis, ndbm, etc. rather than default to looking at all of them. tag each map for "amd -T tag", useful for grouping maps. can override $os and others (so if you don't like "sunos5" default naming, set os=sos5 and it will work with your old maps). and more goodies... - enable-default-selectors: No longer turned on by the configure script or optionally compiled. Code made dynamic and can be turned on or off from the amd.conf file. This code is off by default, and must be turned on by amd.conf's [global] section. - new ports: mips-sgi-irix5.3: configure/compile, not tested i486-ncr-sysv4.3.03: configure/compile, not tested - updated ports: alpha-dec-osf4.0: major code redone sparc-sun-sunos4.1.3: fixed and working mips-sgi-irix6.2: tested with gcc and "cc -32 -Wl,-woff,84" mips-sgi-irix6.4: tested with gcc and "cc -32 -Wl,-woff,84" - better NFS3 port, including more support for proto= and vers=, and automatic determination of proto/vers combination. - conf/nfs_prot/nfs_prot_*.h: all of the NFS protocol header files had to be redone, because of the osf4 port. OSF used very different names for these, and they conflicted with am-utils'. The only solution was to more or less conform to OSF4's naming, and change all the others. - ctl-amd script: improved to look for amd.conf in $prefix/etc and /etc better methods for finding the pid of amd to kill - autoconf support for LDAP. amd/info_ldap.c needs to be written. - wire-test also reports the local IP address. Some systems have multiple, buggy version of get_myaddress(), esp. SunOS and Irix. Note that Solaris x86 has a buggy htonl(). - amd -H prints usage. - bugs fixed: minor TLI problem in fwd_socket mount options properly comma delimited LIBS is set only to the right set of libraries to include selectors-on-default code ignored last selector ent in /defaults assorted code cleanups *** Notes specific to am-utils version 6.0a5: - NFS Version 3 support!!! Works on Solaris 2.5.1. Minimal testing done on Irix 6. Compiles cleanly on DU-4.0 but no tests performed. Will fall back to V2 mounts when V3 is not available. Will also use TCP if possible, UDP otherwise. - Ports to new platforms: alpha-dec-osf4.0 (not tested) i386-pc-bsdi3.0 (tested and working) i386-unknown-freebsd2.2.1 (tested and working) sparc-unknown-linux-gnu (tested and working) - New scripts added: amd2sun: convert amd maps to Sun automount maps ctl-amd: script to start/stop/restart amd ctl-hlfsd: script to start/stop/restart hlfsd expn: expand mail alias (used by hlfsd) lostaltmail: redeliver "lost" mail redirected by hlfsd lostaltmail.conf-sample: sample conf file for lostaltmail wait4amd: run a command once amd is up on a host wait4amd2die: wait for an amd process to die before returning - "amd -v" now includes more info and "amq -v" lists all of it. - new parser for linux specific mount options. - Main bugs fixed: "new toplvl readdir" bug caused amd to dump core handler for SIGCHLD didn't check for all possible children hlfsd leaking file descriptors when home file system was full cdfs/pcfs mounts should not timeout by default hesiod domain names should be compared in case-insensitive manner several printfs in amq were missing \n *** Notes specific to am-utils version 6.0a4: - amd services both TCP and UDP amq requests. This will help because of the limited UDP message size. - "amq -M" code is disabled by default because it is insecure. It is rarely used. Users who wish to use it should run "configure --enable-amq-mount". *** Notes specific to am-utils version 6.0a3: - New tested ports (configures, compiles, and runs): i386-unknown-freebsd2.2 - New ports (configures and compiles correctly, not tested): rs6000-ibm-aix3.2.5 rs6000-ibm-aix4.1.5.0 - More am-utils programs ported to all existing platforms: hlfsd, fsinfo, mk-amd-map, and fixmount. - Shared libraries: a new configure option --enable-shared will build a shared libamu.so, link applications with it, and use it. Reduces binary sizes by 20-30%. This is the first step towards loadable modules, as many changes had to be done to be able to compile and use PIC code. This is code that obviously needs to be generalized to be able to build shared libraries on many other platforms. It was only tested on Solaris 5.5.1. - the file INSTALL contains the latest compatibility table of which platforms am-utils configures, compiles and runs on. - Trimmed down the size of the configure script. Some tests that are not used anywhere were removed. *** Notes specific to am-utils version 6.0a2: - New ports (configures and compiles correctly, not tested): i386-pc-bsdi2.1 hppa1.1-hp-hpux9.01 hppa1.1-hp-hpux10.20 - new configure options: --enable-cppflags[=ARG] configure/compile with ARG (-I) preprocessor flags --enable-libs[=ARG] configure/compile with ARG (-L/-l) library flags - file system, mount table entries, and mount type tests can now look in /lib/modules and /proc/filesystems for statically/dyadically loadable kernel modules (linux) - prefer vfat over msdos/pc/etc file system for PCFS. - moved all fixed headers to include/am_defs. Left only #define/#undef entries in aux/acconfig.h. - make more sense of systems that have full, partial, or no NFS protocol headers. - minor fixes for NetBSD (untested platform). - hesiod map fixed. - buildall -D: new option to run even stricter developer options. - lots of other bugs fixed (see ChangeLog). *** Notes specific to am-utils version 6.0a1: I have it configure and build correctly for the following systems: i386-pc-solaris2.5.1 i386-unknown-freebsd2.1.0 mips-sgi-irix6.2 sparc-sun-solaris2.5.1 sparc-sun-sunos4.1.3 Amq, wire-test, and "amd -v" work on all of the above. A real running amd was only tested and confirmed working on i386-pc-solaris2.5.1 sparc-sun-solaris2.5.1 Many things are still missing: options, features, etc. But for now, let's concentrate on getting the basic functionality working on the more popular systems.
