Update the printerr() function to:
1) Determine whether we'll print the message before going to all the
work of formatting it.
2) Don't just toss away messages that are too long for the buffer.
Print what we can and give an indication of the truncation with
"..." at the end.
3) Use a single buffer rather than two.
4) Messages either go to syslog (with level ERR) or stderr. Don't
send some messages to syslog level DEBUG.
Use setfsuid() rather than seteuid() while creating contexts
Signed-off-by: Kevin Coffman <kwc@citi.umich.edu>
As suggested by Olaf Kirch <okir@suse.de>, use setfsuid() rather than
seteuid() when creating a gss context. This prevents users from using
credentials that do not belong to them, while also preventing them from
doing things like killing, renicing, or changing the priority of the
gssd process while it is processing the context creation.

Do a call to determine mechanisms supported by the gssapi library early.
This allows us to discover early in case the gssapi library is somehow
misconfigured. We can bail out early and give a meaningful message
rather than getting errors on each attempt at a context negotiation.

Correct the definition of mech_used in the gss context to use gss_OID_desc.
This fixes problems on 64-bit machines when referencing the OID.
Also updates write_buffer function to use u_int rather than size_t when
doing calculations.

Allow rpc.nfsd to suppress tcp or udp, and listen on a specific address.
-T - will suppressing listening for TCP connection.
-U - will suppress UDP
-H host - will only listen on that local address
-p port - will listen on that port.
This requires kernel patches which will hopefully be in 2.6.19 and possibly some
earlier test and vendor kernels.

Try to make sure that clientid used for NFSv4 is reliable.
We need to give an IP address to identify this client to the
server.
The current code does a gethostbyname of the hostname. One
some systems this returns 127.0.0.1 or similar, which is not useful.
Instead, use getsockname of the sock used to connect to the server
to confirm that the server is working. This gives the address on the
interface that was chosen to talk to that server, which is the
best address we can find (if there is a NAT in the way, it might
still not work, but in that case there is nothing we can do).

multiple threads for mountd
How about the attached patch against nfs-utils tot? It
adds a -t option to set the number of forked workers.
Default is 1 thread, i.e. the old behaviour.
I've verified that showmount -e, the Ogata mount client,
and a real mount from Linux and IRIX boxes work with and
without the new option.
I've verified that you can manually kill any of the workers
without the portmap registration going away, that killing
all the workers causes the manager process to wake up and
unregister, and killing the manager process causes the
workers to be killed and portmap unregistered.
I've verified that all the workers have file descriptors
for the udp socket and the tcp rendezvous socket, that
connections are balanced across all the workers if service
times are sufficiently long, and that performance is
improved by that parallelism, at least for small numbers
of threads. For example, with 60 parallel MOUNT calls
and a testing patch to make DNS lookups take 100 milliseconds
time to perform all mounts (averaged over 5 runs) is:
