I need a reviewer for a small change to the networking code. On Solaris, the SO_SNDBUF/SO_RCVBUF parameters are clamped by the values of the tcp_max_buf and udp_max_buf parameters. Unfortunately the code in net_util_md.c has been using a private/unsupported interface that no longer exists in Solaris 11. That one is going to take a while to sort out so I'd like to propose a short term solution which is to simply change the fallback values to the out the box defaults (1MB for TCP, 2MB for UDP). That will eliminate the test failures for all cases except where ndd has been used to change the system defaults (probably rare). While I was there, I changed the implementation to just attempt to set the socket options before clamping. The rational is that it should be rare that applications attempt to set these socket options to values larger than the system limit anyway.
One other change included in this webrev is a small change to the newly added ThrowUnknownHostExceptionWithGaiError to address a few compiler warnings.
The webrev the changes is here: http://cr.openjdk.java.net/~alanb/6989190/webrev/ Thanks, Alan.
