      netfilter: log: Fix log-level processing · 16af511a
      由 Joe Perches 提交于 
      auto75914331@hushmail.com reports that iptables does not correctly
output the KERN_<level>.

$IPTABLES -A RULE_0_in  -j LOG  --log-level notice --log-prefix "DENY  in: "

result with linux 3.6-rc5
Sep 12 06:37:29 xxxxx kernel: <5>DENY  in: IN=eth0 OUT= MAC=.......

result with linux 3.5.3 and older:
Sep  9 10:43:01 xxxxx kernel: DENY  in: IN=eth0 OUT= MAC......

commit 04d2c8c8
("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern")
updated the syslog header style but did not update netfilter uses.

Do so.

Use KERN_SOH and string concatenation instead of "%c" KERN_SOH_ASCII
as suggested by Eric Dumazet.

      net: small bug on rxhash calculation · 68622342
      由 Chema Gonzalez 提交于 
      In the current rxhash calculation function, while the
sorting of the ports/addrs is coherent (you get the
same rxhash for packets sharing the same 4-tuple, in
both directions), ports and addrs are sorted
independently. This implies packets from a connection
between the same addresses but crossed ports hash to
the same rxhash.

For example, traffic between A=S:l and B=L:s is hashed
(in both directions) from {L, S, {s, l}}. The same
rxhash is obtained for packets between C=S:s and D=L:l.

This patch ensures that you either swap both addrs and ports,
or you swap none. Traffic between A and B, and traffic
between C and D, get their rxhash from different sources
({L, S, {l, s}} for A<->B, and {L, S, {s, l}} for C<->D)

The patch is co-written with Eric Dumazet <edumazet@google.com>
