+/* There are a few simple rules, which allow for local port reuse by
+ * an application.  In essence:
+ *
+ *      1) Sockets bound to different interfaces may share a local port.
+ *         Failing that, goto test 2.
+ *      2) If all sockets have sk->sk_reuse set, and none of them are in
+ *         TCP_LISTEN state, the port may be shared.
+ *         Failing that, goto test 3.
+ *      3) If all sockets are bound to a specific inet_sk(sk)->rcv_saddr local
+ *         address, and none of them are the same, the port may be
+ *         shared.
+ *         Failing this, the port cannot be shared.
+ *
+ * The interesting point, is test #2.  This is what an FTP server does
+ * all day.  To optimize this case we use a specific flag bit defined
+ * below.  As we add sockets to a bind bucket list, we perform a
+ * check of: (newsk->sk_reuse && (newsk->sk_state != TCP_LISTEN))
+ * As long as all sockets added to a bind bucket pass this test,
+ * the flag bit will be set.
+ * The resulting situation is that tcp_v[46]_verify_bind() can just check
+ * for this flag bit, if it is set and the socket trying to bind has
+ * sk->sk_reuse set, we don't even have to walk the owners list at all,
+ * we return that it is ok to bind this socket to the requested local port.
+ *
+ * Sounds like a lot of work, but it is worth it.  In a more naive
+ * implementation (ie. current FreeBSD etc.) the entire list of ports
+ * must be walked for each data port opened by an ftp server.  Needless
+ * to say, this does not scale at all.  With a couple thousand FTP
+ * users logged onto your box, isn't it nice to know that new data
+ * ports are created in O(1) time?  I thought so. ;-)   -DaveM

- *
- *      1) Sockets bound to different interfaces may share a local port.
- *         Failing that, goto test 2.
- *      2) If all sockets have sk->sk_reuse set, and none of them are in
- *         TCP_LISTEN state, the port may be shared.
- *         Failing that, goto test 3.
- *      3) If all sockets are bound to a specific inet_sk(sk)->rcv_saddr local
- *         address, and none of them are the same, the port may be
- *         shared.
- *         Failing this, the port cannot be shared.
- *
- * The interesting point, is test #2.  This is what an FTP server does
- * all day.  To optimize this case we use a specific flag bit defined
- * below.  As we add sockets to a bind bucket list, we perform a
- * check of: (newsk->sk_reuse && (newsk->sk_state != TCP_LISTEN))
- * As long as all sockets added to a bind bucket pass this test,
- * the flag bit will be set.
- * The resulting situation is that tcp_v[46]_verify_bind() can just check
- * for this flag bit, if it is set and the socket trying to bind has
- * sk->sk_reuse set, we don't even have to walk the owners list at all,
- * we return that it is ok to bind this socket to the requested local port.
- *
- * Sounds like a lot of work, but it is worth it.  In a more naive
- * implementation (ie. current FreeBSD etc.) the entire list of ports
- * must be walked for each data port opened by an ftp server.  Needless
- * to say, this does not scale at all.  With a couple thousand FTP
- * users logged onto your box, isn't it nice to know that new data
- * ports are created in O(1) time?  I thought so. ;-)   -DaveM
