Set version to 1.0.10
Note: 1.0.10 should be used in preference to
1.0.9 especially with kernels 2.6.18 and later
otherwise 'rpc.nfsd N' won't work to change the
number of threads after nfsd has been started.

"rpc.nfsd XX" should not fail if ports are already open.
support/nfs/nfssvc.c: if any ports are already open,
don't try to open any more.
This means that once nfsd is running
rpc.nfsd X
will just change the number of threads, not the
ports in use.

Use uid/gid of -1 to indicate the export's anonuid/anongid should be used
Kernel routine nfsd_setuser() in fs/nfsd/auth.c checks for the
value -1 and defaults the credential's fsuid/fsgid to the
correct anonuid/anongid values for the given export. We should
be passing this value (-1) down when a name mapping cannot be found.

Disable building/installing mount.nfs by default.
mount.nfs does not yet support 'user' option and some others.
To make it support this we need to make it setuid-root, and
some security isses need to be resolved before that can be done
safely.
Don't depend on Kerberos headers when checking librpcsecgss in configure
Signed-off-by: Kevin Coffman <kwc@citi.umich.edu>
Older versions of MIT Kerberos are missing an OID definition, causing
the configure checks for librpcsecgss to fail. We shouldn't be depending
on their libraries during the configure.
- unused variable 'buf'
- emit a declaration for `buf' on demand.
- unused variable 'i'
- declare i immediately before use
- unused value from IXDR_PUT_
- cast to (void)
- type-punned pointer reference
- cast to (void*) first :-(

Temporary patch to do default mapping if we get an error while trying to
map a gss principal to the appropriate uid/gid. This currently returns
hardcoded values. This may be correct, or we may need to try and figure
out the correct values to match the anonuid/anongid for the export.
Change default buffer size increment for readline()
Signed-off-by: Kevin Coffman <kwc@citi.umich.edu>
The readline routine expects much smaller messages than we are passing.
Change the default initial allocation and increment value from 128
to 2048. This saves many calls to realloc().

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.

Specify that the acquire_cred call should only be concerned with returning
Kerberos credentials since this is Kerberos-only functionality.

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.

Comment out the decades-old SCCS id strings from the original Sun
distribution. They cause compile warnings, there is no longer any
reason to try to build them into the binaries, and gcc seems to be
eliding some of them anyway.
