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.
