In the words of the submitter:
---- I've worked to enhance the connect() patches. I've just tested this with the Linux JDK appletviewer on an applet that does a lot of connects, and it works as well as during my previous tests. The connect() patch is now a merge between my older patch and the OpenBSD stuff. It ensures that any async error is returned by connect() instead of getsockopt(SOL_SOCKET, SO_ERROR) as reasonnable systems do. There are also minor patches to implement IPPROTO_TCP for get/setsocktopt(). These are also tested (with Linux Apache). ---- I would appreciate any feedback regarding these changes, as they'd be very useful in 2.2.6. Submitted by: pb@fasterix.freenix.org (Pierre Beyssac)
