[nfs-utils.git] / ChangeLog

2006-04-10 kwc@citi.umich.edu
        Update calls to gss_export_lucid_sec_context()
        
        Change the calls to gss_export_lucid_sec_context() to match the corrected
        interface definition in libgssapi-0.9.
        
2006-04-10 kwc@citi.umich.edu
        Plug memory leaks in svcgssd
        
        Various memory leaks in the svcgssd context processing are eliminated.
        
2006-04-10 kwc@citi.umich.edu
        Fix memory leak of the AUTH structure on context negotiations
        
        Free AUTH structure after completing context negotiation and sending
        context information to the kernel.
        
2006-04-10 kwc@citi.umich.edu
        Fix support/include/config.h.in such as would be done be running autoheader.

        1.0.8-pre3, aclocal/autoconf/automake
        
2006-03-28 kwc@citi.umich.edu
        Use PKGCONFIG to locate gssapi and rpcsecgss header files
        
        Instead of having separate copies of the gssapi and rpcsecgss
        header files, or depending on the Kerberos gssapi header,
        locate the headers now installed with the libgssapi and librpcsecgss
        libraries.
        
        Remove local copies of the gssapi and rpcsecgss header files.
        
        This depends on the configure_use_autotools patch.
        
2006-03-28 kwc@citi.umich.edu
        Add debugging to better detect negotiation of enctype not supported by kernel
        
        Print debugging message indicating the type of encryption keys being sent
        down to the kernel.  This should make it easier to detect cases where
        unsupported encryption types are being negotiated.
        (really this time)

        Don't unnecessarily close and re-open all pipes after every DNOTIFY
        signal.  These unnecessary closes were triggering a kernel Oops.
        Original patch modified to correct segfault when unmounting last
        NFSv4 mount.

        Must still use knowledge of the glue context for pre-1.4 versions of MIT krb5
        
        We need to get access to the internal krb5 context pointer for
        older (pre-1.4) versions of MIT Kerberos.  We get a pointer to
        the gss glue's context.  Get the right pointer before accessing
        the context information.

2006-03-28 kwc@citi.umich.edu
        Update krb5 code to use glue routine lucid context functions
        
        
        
        The gssd code should not know about the glue layer's context structure.
        A previous patch added gss_export_lucid_sec_context() and
        gss_free_lucid_sec_context() functions to the gssapi glue layer.
        Use these functions rather than calling directly to the Kerberos
        gssapi code (which requires the Kerberos context handle rather
        than the glue's context handle).
        
        (really this time)
        
2006-03-28 kwc@citi.umich.edu

        the value to determine how long idmapping entries are cached.
        (Really this time)

        Consolidate gssd and svcgssd since they share much code
        
        Remove directory svcgssd which was only created because the old
        build system could not handle building two daemons in the same
        directory.  This eliminates build complications since gssd and
        svcgssd also share many source files.
        
        This patch effectively removes the utils/svcgssd directory, moving
        all its files to the utils/gssd directory.  File utils/gssd/Makefile.am
        is modified with directions to build both gssd and svcgssd.

        Set libnfsidmap library debugging level and logging function.

        This patch adds a call to the new libnfsidmap library function 
        nfs4_set_debug(), which defines the verbosity level libnfsidmap
        should use as well as the logging function.

        Add CONTINUE_INIT handling to svcgssd. Store the partially complete spkm

        Specify GSS_C_MUTUAL_FLAG rather than GSS_C_ANON_FLAG for
        spkm3.
        
        NOTE: we need a way to pass the appropriate value rather than
        hard-coding this flag.
        
        ---
        Increase size of rpc send/receive buffers
        
        Change the clnt_create() to use routines which allow us to set the
        send and receive buffer size.  This is needed for larger spkm3
        exchanges including certificate chains.
        
        This has the side-effect of skipping the portmap call since
        we specify the port (by specifying the service) when getting
        the server's address information.
        
        ---
        Define _LINUX_QUOTA_VERSION to 1
        
        The rquotad code is written against the "old" kernel quota interface.
        Fedora Core 4 is the only platform known to check for different
        versions, so this should not have any affect on other platforms
        and fixes the build for FC4.

        *support/nfs/rpcmisc.c(rpc_init): is stdin is a socket, but
        is already connected (as e.g. from ssh), don't assume we
        were started by inetd.

2005-11-03 Steve Dickson <SteveD@redhat.com> NeilBrown <neilb@suse.de>
        *utils/idmapd/idmaps.c:
        
        I've recently updated the nfs-utils in rawhide with the
        latest patches from the SourceForge CVS tree and the
        latest CITI patches (1.0.7-4).
        
        In testing these patches, I notice that when the server was started
        and a SIGHUP was sent to rpc.idmapd to open the nfs4.nametoid/channel
        and nfs4.idtoname/channel files, the second open (the nfs4.idtoname one)
        failed because the path (i.e. ic->ic_path) was NULL.
        
        Now the reason the ic_path was NULL was because it was never set
        during the call to nfsdopen(). nfsdopen() looks like:
        nfsdopen(char *path)
        {
             return ((nfsdopenone(&nfsd_ic[IC_NAMEID], IC_NAMEID, path) == 0 &&
             nfsdopenone(&nfsd_ic[IC_IDNAME], IC_IDNAME, path) == 0) ? 0 
               : -1);
        }

        Note: the call to nfsdopenone() is how the path is set in each nfsd_ic[]
        entry and nfsdopen() is only called once.
        
        So when rpc.idmap comes up and the first call to nfsdopenone() fails
        (because the server is not running) the path in nfsd_ic[IC_IDNAME] is
        never filled in because the second nfsdopenone() never happen...
        
        Now there was a CITI patche (idmapd_revert_fix_reopen_on_sighup.dif)
        that tried to address this problem but did seem to fix it.. The
        attached patch fix the problem by initializing both nfsd_ic[IC_IDNAME]
        and nfsd_ic[IC_NAMEID] structures with the needed info...
        I figured since there is no way of changing these paths or filenames
        by command line args, why not just set them during compile time...
        so that's what this patch does.
        
        This patch also changes how nfsdreopen_one() handles the
        case where the event has already been set. Unlike the CITI
        patch (idmapd_revert_fix_reopen_on_sighup.dif) which just
        just does not register the second event, my patch deletes
        the old event and the registers the new one. It just seems like
        the right thing to do since a SIGHUP means a new server just
        started so we probably should create a new event as well...
        
        steved.

        * utils/mountd/mountd.c(get_exportlist): Without this patch,
        showmount -e would sometimes display host names that should really
        have been subsumed under a wildcard entry.

        The problem was that the code in get_exportlist would always
        skip the next group entry after removing one FQDN.

        * utils/mountd/mountd.c: Eliminate 3 syslog message that are
        logged for successful events. 
        * utils/mountd/mountd.c: make sure the correct hostname is used in
        the SM_NOTIFY message that is sent from a rebooted server which

        *utils/statd/montor.c(sm_mon_1_svc): as above
        *support/nfs/xlog.c(xlog): Changed xlog to use LOG_INFO instead of
        LOG_DEBUG so debug messages will appear w/out any config changes
        to syslog.conf. 

        
2005-09-02 Mike Frysinger <vapier@gentoo.org>
        * utils/rquotad/rquota_server.c(getquotainfo): use explicit
        struture-member copying rather than memcpy, as the element
        sizes are the same on all architectures.

        Add option to set rpcsec_gss debugging level (if available)

        Changes to allow gssd/svcgssd to build when using Hiemdal Kerberos
        libraries.  Note that there are still run-time issues preventing
        this from working when shared libraries for libgssapi and librpcsecgss
        are used.
        
2005-08-26 Kevin Coffman <kwc@citi.umich.edu>
        Remove the rpcsec_gss code and rely on an external library instead.

2005-08-26 Kevin Coffman <kwc@citi.umich.edu>
        *utils/mountd/mountd.c:
        mountd currently always returns AUTH_NULL and AUTH_SYS as the
        allowable flavors in mount replies.  We want it to also return gss
        flavors when appropriate. For now as a hack we just have it always
        return the KRB5 flavors as well. 

        *utils/mountd/cache.c:
        
        When attempting to mount an NFSv4 pseudofilesystem (fsid=0) and the
        actual exported directory does not exist on the server, rpc.mountd
        doesn't check the directory exists (when fsidtype=1, i.e. using fsid,
        but does check for fsidtype=0, i.e. using dev/ino).  The non-existent
        exported directory path with fsid=0 is written to the kernel via
        /proc/net/rpc/nfsd.export/channel, which leads to path_lookup() to
        return ENOENT (seems appropriate).  Unfortunately, the new_cache
        approach ignores errors returned when writing via the channel file so
        that particular error is lost and the mount request is silently ignored.
        
        Assuming it doesn't make sense to revamp the new_cache/up-call method to
        not ignore returned errors, it seems appropriate to fix the case where
        rpc.mountd doesn't check for the existence of an exported directory with
        fsid= semantics.  The following patch does this by moving the stat() up
        so it is done for both fsidtype's.  I'm not certain whether the other
        tests need to be executed for fsidtype=1, but it doesn't appear to hurt
        [Not exactly true: the comparison of inode numbers caused problems so
        now it's kept for fsidtype=0 only].
        
        Would it be also desirable to log a warning for every error, if any,
        returned by a write to any of the /proc/net/rpc/*/channel files which
        would otherwise be ignored (maybe under a debug flag)?

        * gssd/mountd/svcgssd: Changes gssd, svcgssd, and mountd to ignore a
        SIGHUP rather than dying.

        * many: Remove the gssapi code and rely on an external library instead.

2005-08-26 Kevin Coffman <kwc@citi.umich.edu>
        * utils/exportfs/exports.man: Document the "crossmnt" export export option
        * utils/gssd/krb5_util.c: 
        Add better debugging and partially revert the function
        check for gss_krb5_ccache_name.
        
        For MIT Kerberos releases up to and including 1.3.1, we *must*
        use the routine gss_krb5_ccache_name to get the K5 gssapi code
        to use a different credentials cache.
        
        For releases 1.3.2 and on, we want to use the KRB5CCNAME
        environment variable to tell it what to use.
        (A problem was reported where 1.3.5 was being used, our
        code was using gss_krb5_ccache_name, but the underlying
        code continued to use the first (or default?) credentials
        cache.  Switching to using the env variable fixed the problem.
        I cannot recreate this problem.

        *utils/gssd/krb5_util.c:
        Andrew Mahone <andrew.mahone@gmail.com> reported that reiser4
        always has DT_UNKNOWN.  He supplied patch to move the check
        for regular files after the stat() call to correctly find
        ccache files in reiser4 filesystem.
        
        Also change the name comparison so that the wrong file is
        not selected when the substring comparison is done.

        *utils/gssd/krb5_util.c:
        Limit the set of encryption types that can be negotiated by
        the Kerberos library to those that the kernel code currently
        supports.
        
        This should eventually query the kernel for the list of
        supported enctypes.

        *utils/gssd/gss_util.c, utils/svcgssd/svcgssd_main_loop.c:
        Print more information in error messages to help debugging failures.

        *utils/svcgssd/svcgssd_proc.c: Increase token buffer size and
        update error handling so that a response is always sent.

        *utils/svcgssd/svcgssd_proc.c: Add support to retrieve
        supplementary groups. 
        
        
2005-08-26 Kevin Coffman <kwc@citi.umich.edu>
        * configure.in etc
        Consolidate some of the Kerberos checking instead of repeating
        the same things for MIT and Heimdal.
        Also adds more checks to distinguish 32-bit from 64-bit
        (mainly for gssapi.h)
        Fix svcgssd Makefile so make TOP=../../ works correctly there.
        Enable running a modern autoheader.
        * utils/gssd/gss_oids.c: Use correct OID value for SPKM-3
        * utils/gssd/gss_util.c: Fix build with older MIT releases that do not define GSS_C_NT_HOSTBASED_SERVICE
        * utils/gssd/write_bytes.h, support/include/gssapi/gssapi.h:
        Length of gss_buffer_desc is a size_t which is 64-bits on a
        64-bit machine.  Kernel code expects 32-bit integer for length.
        Coerce length value into a 32-bit value when reading from or
        writing to the kernel.
        Change gssapi.h to use datatype size values obtained from
        configure rather than hard-coded values.
        * utils/idmapd/idmapd.c: The EV_INIT check here was wrong, and was
        causing idmapd to become unresponsive to server requests after
        receiving a sighup. 
        * utils/idmapd/idmapd.c: Idmapd should flush the server id<->name
        caches when its started. 

2005-04-12  G. Allen Morris III <gam3@gam3.net>

        * All Makefile: added TOP as needed for easier compile.

        * utils/nfsstat/nfsstat.c: added NFS V4 support; added the -m
          option; Added -2, -3, and -4 options; changed -a option to -v
          option; added long options; changed default output to not
          show V2 NFS statistics unless used.

        * utils/nfsstat/nfsstat.man: Documented above changes; changed
          authors email address; added BUGS section.

        "nfsddebug" and update flag names.
        * configure.in, nodist/* redhat/* nfs-utils.spec*: remove redhat
        specific files (as no-one actually uses them, especially not
        redhat), and the nodist /etc files (as they drift out-of-date, and
        the debian directory provides a suitable example.
        * utils/svcgssd_proc.c(get_ids): fix memory leak
        * utils/svcgssd/svcgssd_proc.c: Rely on count of the number of

        file for the default domain, instead of doing that ourselves.

        downcall fails. 
        * utils/gssd/gssd_proc.c: We were forgetting to restore the euid

        that it needed to.

        * debian/nfs-kernel-server.init: Cosmetic changes.

2003-07-18 NeilBrown <neilb@cse.unsw.edu.au>

        Release 1.0.5:
         1.0.4 was a bit of a brown-paper-bag-release because of the extra
         'free' in auth.c.  So I'm releasing this just a few days later.

        * support/nfs/cacheio.c(cache_flush): Correct test for 'open
        failed'
        * utils/exportfs/exportfs.c(main): If "-f" given as lone option,
        check if new_cache is enabled, error if not, flush and exit if it
        is. 
        * utils/exportfs/exportfs.man: Explain -f option and explain the
        two different modes that exportfs can work in.
        * utils/mountd/mountd.c: Do not change RLIMIT_NOFILE if the -o
        option wasn't given.
        * utils/mountd/mountd.man: Record the change if default behaviour
        for RLIMIT_NOFILE.
        * configure.in, nfs-utils.spec: update version to 1.0.5 and
        run autoconf
        
2003-07-15 NeilBrown <neilb@cse.unsw.edu.au>

        * utils/mountd/mountd.c(main): getopt string fix for 'o'
        * utils/mountd/auth.c(auth_authenticate): remove extra 'free'
        * utils/exportfs/exportfs.c(main): make 'exportfs -f' just flush
        the caches.
        * support/include/nfs/export.h: Reserve a bit for possible ACL
        related use.
        
2003-07-03 NeilBrown <neilb@cse.unsw.edu.au>

        * utils/exportfs/nfsd.man: new man page for nfsd filesystem. Also
        assorted changed to cope with section 7 of the manual.
        * configure.in, nfs-utils.spec: Update version to 1.0.4
        * run autoconf

        This is a 'pre-release' for 1.1.0  Hopefully 1.1.0 will be the
        baseline for 2.6 and 2.8.  I.e. it should continue to work right
        through the 2.8 (or 3.0) kernel series.  Previous releases wont.

2003-07-04 NeilBrown <neilb@cse.unsw.edu.au>    
        Steve Dickson <SteveD@redhat.com>

        statd cleanup:
        * utils/statd/statd.c: create a pidfile with pid of statd, and
        truncate it when statd exists.
        * utils/statd/statd.c: drop privs by setuid to owner of SM_DIR,
        and warn if this is root.
        * utils/statd/statd.c: when statd forks, connect child to parent
        with a pipe, and send a byte down the pipe once the child is
        working properly.
        * Makefile: create and chown sm, sm.bak, state when "make install"
        * configure.in: add --with-statduser= option which defaults to
        "rpcuser" or "nobody"
        * config.mk.in: pass "statduser" through to Makefile
        
2003-07-03 NeilBrown <neilb@cse.unsw.edu.au>

        * support/include/nfs/nfs.h: Make sure correct __kernel_dev_t is
        used as the size was changed somewhere in 2.5.60-2.5.70.  Without
        this nfs-utils compiles against 2.6 headers will not work on a
        2.4 kernel.     
        
2003-07-03 NeilBrown <neilb@cse.unsw.edu.au>

        * support/nfs/nfssvc.c(nfssvc): If /proc/fs/nfs/threads exists,
        set number of threads by writing to there.  This means it will
        still work when the syscall interface goes away in 2.7.

2003-07-03 NeilBrown <neilb@cse.unsw.edu.au>
        fumihiko kakuma <kakmy@mvh.biglobe.ne.jp>

        * utils/exportfs/exportfs.c(unexportfs): improve host comparison
        so as to only export the wildcard exports that were asked for.
        * support/export/export.c(export_allowed): changed to return the
        nfs_export rather than a "struct exportent", as m_changed is
        needed by called
        * support/export/rmtab.c(rmtab_read): modified to deal with
        interface change for export_allowed(), and enhanced to preserve
        m_changed flag when a wild-card export causes the creation of
        a non-wildcard export.
        
2003-07-02 NeilBrown <neilb@cse.unsw.edu.au>
        Steve Dickson <SteveD@redhat.com>

        * utils/mountd/mountd.man: Add valid kinds of debugging.
        * utils/mountd/mountd.c(main): ignore SIGPIPE
        * utils/nfsstat/nfsstat.c: fine-tune printing of warning so
        we don't get warnings about unavailable stats that weren't asked
        for.
        
2003-06-24 NeilBrown <neilb@cse.unsw.edu.au>

        * support/nfs/nfsexport.c(exp_unexp): When unexporting filesystems
        via /rpc/net/rpc/nfsd*/channel, set the expiry date to 1, not
        'forever', so things disappear out of the cache rather than just
        be ignored. 
        
2003-06-16  "J. Bruce Fields" <bfields@fieldses.org>

        * utils/mountd/cache.c(nfsd_fh): don't export the export_ent
        if it wasn't found.

2003-06-16  NeilBrown   <neilb@cse.unsw.edu.au>

        * debian/nfs-kernel-server.init,etc/nodist/nfs-server,
        etc/redhat/nfs.init: when checking if V3 is supported, make sure
        nfs server 'knows' about 127.0.0.1 first.
        
2003-06-10  Chip Salzenberg  <chip@pobox.com>

        * support/nfs/xlog.c (xlog): Fix off-by-one buffer overflow bug.

        support/nfs/export.c, utils/exportfs/exportfs.c,
        utils/mountd/mountd.c: new export option "mountpoint"
        If no path is given, then the export point must be a
        mount point, or it won't be exported.  If a path is 
        given (e.g. mountpoint=/path) then that path must be
        a mountpoint or the exportpoint won't be exported.
        * utils/exportfs/exportfs.man: document mountpoint option.
        * support/misc/mountpoint.c: New file with is_mountpoint()
        to determine if something is a mountpoint.
        
2003-05-23  NeilBrown <neilb@cse.unsw.edu.au>

        * utils/mountd/cache.c(cache_get_filehandle): take a separate path
        argument as we might not be getting the filehandle for the
        mountpoint.
        * utils/mountd/mountd.c(get_rootfh): pass real path when calling
        cache_get_filehandle.
        * utils/mountd/mountd.c(get_rootfh): check export point and
        requested directory are on the same filesystem, and complain if
        not.
        
2003-05-22  NeilBrown <neilb@cse.unsw.edu.au>

        * utils/mountd/auth.c(auth_authenticate_internal): make sure
        portnumber is still checked when using new cache lookup.
        
2003-05-21  NeilBrown <neilb@cse.unsw.edu.au>

         to flush
        * utils/exportfs/exportfs.c: add -f option to fully flush cache.
        * support/export/xtab.c: Only rename new xtab into place if it has
         changed, thus preserving modify date for exportfs to use when
         flushing.
        * support/nfs/cacheio.c: Add cache_flush
        * support/export/xtab.c: Only rename new xtab into place if it has

         flushing.
        
2003-05-21  NeilBrown <neilb@cse.unsw.edu.au>

        * support/export/client.c: Add client_compose, client_member to
        handle new composite client names
        * support/include/exportfs.h: Declare above functions.
        * utils/mountd/auth.c: use client_compose to determine calling
        client if new cache is being used.
        * utils/mountd/auth.c: call cache_export to export a filesystem if
        new_cache, check if new cache is used, and call my_svc_run instead
        of svc_run
        * utils/mountd/svc_run.c: new file defining my_svc_run
        * utils/mountd/cache.c: new file for handling cache upcalls.

        * tools/rpcgen/rpc_main.c(find_cpp): removed
        * tools/rpcgen/rpc_main.c(open_input): use execvp to find "cpp", 
        then try hard-coded paths.

        * debian/changelog: Version 1.0.3-1.

        * utils/mountd/rmtab.c (slink_safe_rename): real_newpath should be
        "const char*", not "char*".

2003-03-26 NeilBrown <neilb@cse.unsw.edu.au>

        * configure.in (VERSION): Set to "1.0.3".
        * nfs-utils.spec: Likewise.

        * support/nfs/nfsexport.c: export and unexport through
        /proc/rpc/*/channel if possible, as old syscall interface
        may not survive into 2.6 on all architectures.
        
2003-02-19 NeilBrown <neilb@cse.unsw.edu.au>    
        Ben Leslie <benno@sesgroup.net>

        * support/nfs/rpcmisc.c(rpc_init):  change test for ignoring
        "defport" from (__rpcfdtype == 0) to (__rpcpmstart==0).  The
        former would incorectly ignore defport if the application 
        explicitly set __rpcfdtype.  The later is sufficient to avoid the
        special handling in the case where stdin is an internet socket.

        * utils/mountd/mountd.c(main): Add 'n' to option list in
        getopt_long as this is a short form of --no-tcp which want being
        checked.

        card characters match a period.  They do.
        
2002-10-15  Juan Gomez <juang@us.ibm.com>

        * utils/mountd/rmtab.c (slink_safe_rename): New. Support
        symlink.

        Add support for fsid=nn export option so that device
        numbers don't go in filehandles.
        * support/export/nfsctl.c(expsetup): if exporting and NFSEXP_FSID
        is set, pass the fsid in-place of the device number
        * support/nfs/exports.c: parse and print fsid= option.
        Also check if efname has been set, and use "command line"
        instead in error messages.
        Also, use strtol instead of atoi for anon[ug]id= so that
        bad numbers cause errors.

        * support/export/client.c (client_lookup) : add "canonical"
        flag which says that the hostname is known to be canonical, so
        don't do a lookup

        flag to be passed down to client_lookup
        * support/export/export.c (export_lookup) : Likewise

        (is_export != 1).

        routine. Functionality is completely included in
        exports_update

Wed Sep 08 16:49:32 1999  Neil Brown <neilb@cse.unsw.edu.au>

1/ utils/mountd/rmtab.c::mountlist_list

     This routine stats the rmtab file to see if it has changed.  It
     if has, it cleans up it's old copy of the data. But it still
     always re-read the file, thus returning multiple copies of the
     data on consecutive calls without intervening changes.
     "Showmount -a" didn't show this as it appears to sort/unique the
     data, but 'strace showmount -a' showed that the size of the
     datagram that it received grew.

     I moved the getrmtabent loop inside the mtime test.

2/ utils/exportfs/exportfs.c
   
     Many routines used the m_path field of m_export instead of
     e_path.
     According to the comment in nfslib.h, m_path should only
     be used when processing a mount request (i.e. in mountd)
     where the mountpoint may be a subdirectory of the export point.

     I changed all occurances of m_path to e_path


3/ utils/exportfs/exportfs.c:main

      extra arguments are not meaningful with -a or -r, but
      exportfs accepted them and then ignored the -a/-r, expect that
      -r would still unexport everything first.

      I generate an error if there are extra args and f_all

4/ utils/exportfs/exportfs.c:main
     extract dump out as a special case.

5/ utils/exportfs/exportfs.c
     made f_reexport a local variable.


6/ utils/exportfs/exportfs.c:main,exportall

    support/export/rmtab.c
       only  mayexport on newly created entries, don't set xtabent at all

7/ support/include/nfslib.h

      add #define _PATH_PROC_EXPORTS to be /proc/fs/nds/exports

8/ support/export/xtab.c

      xtab_mount_read loads data from _PATH_PROC_EXPORTS if it exists,
      else from xtab


9/ support/export/xtab.c

      xtab_mount_read now sets m_exported, and NOT
        xtabent and mayexport

      removed the append arguement from xtab_write as it was
        never used.

      added is_export flag to xtab_write similar to xtab_read
        if is_export, only write entries with m_xtabent or m_addxtab
        if !is_export, only write entries with m_exported
     
10/ support/export/export.c::export_allowed_internal

      added test for exp->m_mayexport, as the export tree
        may have entries that are no longer allowed to be exported,
        and so shouldn't caused deduced exported by rmtab_read

11/ utils/exportfs/exportfs.c::main
        error checking of flags.

12/ utils/exportfs/exportfs.c

        total rewrite of export and unexport logic.
        We now:
        -  build an exportslist of valid exports, based on
           current etab file  and arguments,
        -  read rmtab to instantiate relevant wild card entries
        -  read etab to find out what is currently exported
        -  synchronise intention with reality
        -  write out etab and xtab

13/  various
        discard the m_addxtab flag
        add m_changed flag so we know what to report in exportfs

14/ utils/mountd/auth.c:auth_authenticate

        the value returned by gethostbyaddr was trusted.

        It now follows this with a call to gethostbyname
        and checks that the address is in the list.

15/ support/export/nfsctl.c::cltsetup,expsetup

        force client names to lowercase as kernel is
        sensitive to case

16/ quietened a few compiler warnings

17/ support/export/client:client_lookup

     look for pre-existing client with same name before creating
        a new one.

18/ support/include/exportfs.h

     The ordering of the MCL_* enum was:
        ANONYMOUS, FQDN, SUBNETWORK, WILDCARD, NETGROUP

     I moved ANONYMOUS to the end.

     The ordering is significant when an export entry is being searched for to 
        match a given address.  There are two problems with ANONYMOUS being first.

        1/ if a directory is exported rw to a couple of hosts and ro to everyone else,
           then the ro case will always be found first and the privileged hosts won't get
           their privilege
        2/ When mountd gets a request to mount an ANONYMOUSly exported tree, it creates a FQDN
           export entry for the specific host, and writes it to xtab.
           When another request comes from the same host, the ANONYMOUS entry is found again, 
           before the new FQDN entry, so it creates another FQDN entry and writes it to xtab
           again.  If causes bloat in xtab.

      Putting ANONYMOUS at the end reflects it's nature as a catch-all

19/ utils/exportfs/exportfs.man
        many updates to the man page to reflect changes to the code

-----------------------



TODO:

- allow exportfs to modify rmtab file
- make sure kernel never gets two clients with same IP address
    - possible kernel should reject
    - needs to be some way to lookup client in kernel by IP address
- maybe get kernel to do case-insensitive comparisons on client names
- remove unused clients from kernel

- change etab to xtab and xtab to xtab.active

- timestamp and/or statd-stamp in rmtab for removing old entries.
