*** 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 overlow changes. Audited all use
of strncpy/strlcpy to ensure safety.
- bugs fixed:
* pawd handles all file systems
* fix double-free in type:=nfsx

- 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.

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)

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()

- 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.

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.

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

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

- 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 <name> 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.
