Hi all,

For us Bull, TI-RPC is just a mean to supply IPv6 support for RPC.
We always have considered that it is a raw code with bugs and code =

craps, that has not been tested enough.
We just use and supply it to test IPv6 support for NFSv4. And the code =

is stable enough to do tests with NFSv4 and IPv6.
However, we are developping some tests to improve its reliability, =

stability, performance, to make it acceptable in a more general context.

In the past, we discussed with glibc people to extend SunRPC library =

with IPv6 features. Uli Drepper clearly refused and explained that he =

did not want to see new bugs entering in RPC glibc library. He seems to =

consider that RPCs should not be in the glibc, and introduction of new =

features must be done in an external library.

That's why we decided to port an external tirpc library from FreeBSD =

(which is based on the same Sun code than Wietse's )
