note 83877 added to function.socket-create

It took some investigation to understand the bit about raw sockets requiring root access and raw sockets being required to perform a seemingly simple "ping" on a Linux server. My source of confusion was that the regular command line "ping" utility did not require me to be root to exec it, so what was the difference? I found the answer starting with a forum posting to look up man 7 raw for raw sockets info which reveals: "Only processes with an effective user ID of 0 or the CAP_NET_RAW capability are allowed to open raw sockets." So root is not the only way; the ping utility normally works because it has suid permission. There is some interesting source code however that allows you to selectively assign the CAP_NET_RAW capability without the need for suid.
