Subject: [PATCH] net: fix kernel_accept() error path
Date: Thu, 04 Oct 2007 16:20:05 -0400 [thread overview]
Message-ID: <47054AF5.4050409@cybernetics.com> (raw)
If accept() returns an error, kernel_accept() releases the new socket
but passes a pointer to the released socket back to the caller. Make it
pass back NULL instead.
