ba96b53461 Reinstate one more old bugfix that got lost in the tirpc commit:
always look up -network and -mask addresses numerically before
trying getnetbyname(). Without this, we may end up attempting DNS
queries on silly names such as "127.0.0.0.my-domain.com". See the
commit log from revisions 1.21 and 1.20 for further details.

701f37e23c When exporting a directory that is not a mountpoint, mountd repeatedly
removes the last path component until the mount() succeeds. However,
the code never checks if it has passed the mountpoint, so in some
cases where the mount() never succeeds, it can end up applying the
flags from a mounted filesystem to the underlying one.

Add a sanity check to the code which removes the last path component:
test that the fsid associated with the new path is the same as that
of the old one.

e293eec299 The introduction of IPv6 support from NetBSD's mountd invalidated
a number of assumptions related to the parsing of options in
/etc/exports, and missed a few necessary new error checks.

The main problems related to netmasks: an IPv6 network address
missing a netmask would result in the filesystem being exported to
the whole IPv6 world, non-continuous netmasks would be made continuous
without any warnings, and nothing prevented you specifying an IPv4
mask with an IPv6 address.

This change addresses these issues. As a side-effect we now store
netmasks in sockaddr structs (this matches the kernel interface,
and is closer to the way it used to be). Add a flag OP_HAVEMASK to
keep track of whether or not we have successfully got a mask from
any source. Replace some mask-related helper functions with versions
that use the sockaddr-based masks.

Also tidy up get_net() and fix the code that interprets IPv4 partial
networks such as "127.1" as network rather than host addresses.
Properly zero out some structures that were ending up partially
containing junk from the stack, fix a few formatting issues, and
add a comment noting some assumptions about export arguments.

439a88e5fd Fix a long-standing bug relating to the handling of SIGHUP: mountd
would call malloc, stdio and other library functions from the signal
handler which is not safe due to reentrancy problems.

Instead, add a simple handler that just sets a flag, and call the
more complex function from main() when necessary. Unfortunately to
be able to check this flag, we must expand the svc_run() call, but
the RPC library makes that relatively easy to do.

3f3a6a4168 A few more mountd cleanups:
- Remove some horrible code that faked a "struct addrinfo" to be
  later passed to freeaddrinfo(). Instead, add a new group type
  "GT_DEFAULT" used to denote that the filesystem is exported to the
  world, and treat this case separately.
- Don't clear the AI_CANONNAME flag in a struct addrinfo returned
  by getaddrinfo. There's still a bit more struct addrinfo abuse
  left in here.
- Simplify do_mount() slightly by using an addrinfo pointer to keep
  track of the current address.

023d47cd6f Various bugfixes and cleanups, mainly from Martin Blapp:
- Revert del_mlist() to its pre-tirpc prototype. Unlike NetBSD's version,
  ours lets the caller generate any syslog() messages, so that it
  can include the service name in the message.
- Initialise a few local variables to clarify the logic and avoid some
  compiler warnings.
- Remove a few unused functions and local variables, and fix some
  whitespace issues.
- Reinstate the logic for avoiding duplicate host entries that got
  removed accidentally in revision 1.41 (added in r1.5). This bit
  was submitted in a slightly different form by Thomas Quinot.

f67e4a8fc7 Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and
associated changes that had to happen to make this possible as well as
bugs fixed along the way.

  Bring in required TLI library routines to support this.

  Since we don't support TLI we've essentially copied what NetBSD
  has done, adding a thin layer to emulate direct the TLI calls
  into BSD socket calls.

  This is mostly from Sun's tirpc release that was made in 1994,
  however some fixes were backported from the 1999 release (supposedly
  only made available after this porting effort was underway).

  The submitter has agreed to continue on and bring us up to the
  1999 release.

  Several key features are introduced with this update:
    Client calls are thread safe. (1999 code has server side thread
    safe)
    Updated, a more modern interface.

  Many userland updates were done to bring the code up to par with
  the recent RPC API.

  There is an update to the pthreads library, a function
  pthread_main_np() was added to emulate a function of Sun's threads
  library.

  While we're at it, bring in NetBSD's lockd, it's been far too
  long of a wait.

  New rpcbind(8) replaces portmap(8) (supporting communication over
  an authenticated Unix-domain socket, and by default only allowing
  set and unset requests over that channel). It's much more secure
  than the old portmapper.

  Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
  to support TI-RPC and to support IPV6.

  Umount(8) is also fixed to unmount pathnames longer than 80 chars,
  which are currently truncated by the Kernel statfs structure.

18d474781f Switch to using a struct xucred instead of a struct xucred when not
actually in the kernel.  This structure is a different size than
what is currently in -CURRENT, but should hopefully be the last time
any application breakage is caused there.  As soon as any major
inconveniences are removed, the definition of the in-kernel struct
ucred should be conditionalized upon defined(_KERNEL).

This also changes struct export_args to remove dependency on the
constantly-changing struct ucred, as well as limiting the bounds
of the size fields to the correct size.  This means: a) mountd and
friends won't break all the time, b) mountd and friends won't crash
the kernel all the time if they don't know what they're doing wrt
actual struct export_args layout.

d9b1099758 Just when you thought it was safe...
- getnetgrent.c: address some NIS compatibility problems. We really need
to use the netgroup.byuser and netgroup.byhost maps to speed up innetgr()
when using NIS. Also, change the NIS interaction in the following way:

If /etc/netgroup does not exist or is empty (or contains only the
NIS '+' token), we now use NIS exclusively. This lets us use the
'reverse netgroup' maps and is more or less the behavior of other
platforms.

If /etc/netgroup exists and contains local netgroup data (but no '+').
we use only lthe local stuff and ignore NIS.

If /etc/netgroup exists and contains both local data and the '+',
we use the local data nd the netgroup map as a single combined
database (which, unfortunately, can be slow when the netgroup
database is large). This is what we have been doing up until now.

Head off a potential NULL pointer dereference in the old innetgr()
matching code.

Also fix the way the NIS netgroup map is incorporated into things:
adding the '+' is supposed to make it seem as though the netgroup
database is 'inserted' wherever the '+' is placed. We didn't quite
do it that way before.

(The NetBSD people apparently use a real, honest-to-gosh, netgroup.db
database that works just like the password database. This is
actually a neat idea since netgroups is the sort of thing that
can really benefit from having multi-key search capability,
particularly since reverse lookups require more than a trivial
amount of processing. Should we do something like this too?)

- netgroup.5: document all this stuff.

- rcmd.c: some sleuthing with some test programs linked with my own
version of innetgr() has revealed that SunOS always passes the NIS
domain name to innetgr() in the 'domain' argument. We might as well
do the same (if YP is defined).

- ether_addr.c: also fix the NIS interaction so that placing the
'+' token in the /etc/ethers file makes it seem like the NIS
ethers data is 'inserted' at that point. (Chances are nobody will
notice the effect of this change, which is just te way I like it. :)

666343f7f0 Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount).  The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server.  It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs.  Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.

af8a974897 Fixed stupid bug in mountd: it would seem that the kernel doesn't allow
you to push the same host into its NFS export lists twice, but mountd
tries to do it anyway. This means that putting:

/some_file_system -ro host1 host1

in your /etc/exports file causes an error. This is bogus: mountd should be
smart enough to ignore the second instance of host1. This can be a problem
in some configurations that use netgroups. For example, each host in my
netgroups database is has two entries:

startide (startide,-,) (startide.ctr.columbia.edu,-,)

When mountd sees this, it tries to put startide.ctr.columbia.edu into the
export list *twice*. Just listing 'startide' /etc/exports list will also
screw up because mountd will try to resolve the netgroup 'startide' instead
of the hostname 'startide.'

My solution is watch for duplicate entries in get_host() and mark them
as grouptype GT_IGNORE, which do_mount() will now cheefully throw away.
This is a bit of a kludge, but it was the least obtrusive fix I could
come up with.

Also silenced a compiler warning: arguments passwd to xdr_long() should
be u_long, not int. :)
