ECN support incorrectly maps ECN BESTEFFORT packets to TC_PRIO_FILLER
(1) instead of TC_PRIO_BESTEFFORT (0)

This means ECN enabled flows are placed in pfifo_fast/prio low priority
band, giving ECN enabled flows [ECT(0) and CE codepoints] higher drop
probabilities.

This is rather unfortunate, given we would like ECN being more widely
used.

When the pipe uses aligned-mode data packets, we must reserve 4 bytes
instead of 3 for the pipe protocol header. Otherwise the Phonet header
would not be aligned, resulting in potentially corrupted headers with
later unaligned memory writes.

zero-terminated strings are not checked.  When they are used as argument
to a format string containing "%s" in request_module(), some sensitive

We use the reply tuples when limiting the connections by the destination
addresses, however, in SNAT scenario, the final reply tuples won't be
ready until SNAT is done in POSTROUING or INPUT chain, and the following
nf_conntrack_find_get() in count_tem() will get nothing, so connlimit
can't work as expected.

In this patch, the original tuples are always used, and an additional
member addr is appended to save the address in either end.

Much of ip_vs_leave() is unnecessary if CONFIG_SYSCTL is undefined.

I tried an approach of breaking the now #ifdef'ed portions out
into a separate function. However this appeared to grow the
compiled code on x86_64 by about 200 bytes in the case where
CONFIG_SYSCTL is defined. So I have gone with the simpler though
less elegant #ifdef'ed solution for now.
