SubjectSO_PASSCRED broken in 2.4 ?

Hi !

I have a program that uses the SO_PASSCRED socket option on a connected UNIX
socket.

This program works fine under 2.2, but under 2.4 I receive an EOPNOTSUPP when
doing the recvmsg() call on the new socket after a client connects.

Is this a known feature, or should I go look for the problem ?
I did peek into the net/unix and net/core code and compared 2.2.14 and 2.4,
but this is out of my league. Sorry.

I'm running 2.4.0-test2 on i686 SMP.

Thanks,
