db7a94d60f highmem: Export totalhigh_pages.
Hash et al. sizing code in SCTP wants to make the
calculation totalram_pages - totalhigh_pages, just
like TCP.  But this requires an export for the
CONFIG_HIGHMEM case to work.

This kernel panic appears with CONFIG_NET_NS=y.

How to reproduce ?

    On the buggy host (host A)
       * ip addr add 1.2.3.4/24 dev eth0

    On a remote host (host B)
       * ip addr add 1.2.3.5/24 dev eth0
       * iptables -A INPUT -p tcp -s 1.2.3.4 -j DROP
       * ssh 1.2.3.4

    On host A:
       * netstat -ta or cat /proc/net/tcp

This bug happens when reading /proc/net/tcp[6] when there is a req_sock
at the SYN_RECV state.

When a SYN is received the minisock is created and the sk field is set to
NULL. In the listening_get_next function, we try to look at the field 
req->sk->sk_net.

When looking at how to fix this bug, I noticed that is useless to do
the check for the minisock belonging to the namespace. A minisock belongs
to a listen point and this one is per namespace, so when browsing the
minisock they are always per namespace.

33ad798c92 tcp: options clean up
This should fix the following bugs:
  * Connections with MD5 signatures produce invalid packets whenever SACK
    options are included
  * MD5 signatures are counted twice in the MSS calculations

Behaviour changes:
  * A SYN with MD5 + SACK + TS elicits a SYNACK with MD5 + SACK

    This is because we can't fit any SACK blocks in a packet with MD5 + TS
    options. There was discussion about disabling SACK rather than TS in
    order to fit in better with old, buggy kernels, but that was deemed to
    be unnecessary.

  * SYNs with MD5 don't include a TS option

    See above.

Additionally, it removes a bunch of duplicated logic for calculating options,
which should help avoid these sort of issues in the future.

c1e20f7c8b tcp: RTT metrics scaling
Some of the metrics (RTT, RTTVAR and RTAX_RTO_MIN) are stored in
kernel units (jiffies) and this leaks out through the netlink API to
user space where the units for jiffies are unknown.

This patches changes the kernel to convert to/from milliseconds. This
changes the ABI, but milliseconds seemed like the most natural unit
for these parameters.  Values available via syscall in
/proc/net/rt_cache and netlink will be in milliseconds.

3072367300 pkt_sched: Manage qdisc list inside of root qdisc.
Idea is from Patrick McHardy.

Instead of managing the list of qdiscs on the device level, manage it
in the root qdisc of a netdev_queue.  This solves all kinds of
visibility issues during qdisc destruction.

The way to iterate over all qdiscs of a netdev_queue is to visit
the netdev_queue->qdisc, and then traverse it's list.

The only special case is to ignore builting qdiscs at the root when
dumping or doing a qdisc_lookup().  That was not needed previously
because builtin qdiscs were not added to the device's qdisc_list.

d89cbbb1e6 ipv4: clean the init_ipv4_mibs error paths
After moving all the stuff outside this function it looks
a bit ugly - make it look better.

Proc temporary uses stats from init_net.

BTW, TCP_XXX_STATS are beautiful (w/o do { } while (0) facing) again :)

852566f53c mib: add netns/mib.h file
The only structure declared within is the netns_mib, which will
carry all our mibs within. I didn't put the mibs in the existing
netns_xxx structures to make it possible to mark this one as
properly aligned and get in a separate "read-mostly" cache-line.

a0c80b80e0 pkt_sched: Make default qdisc nonshared-multiqueue safe.
Instead of 'pfifo_fast' we have just plain 'fifo_fast'.
No priority queues, just a straight FIFO.

This is necessary in order to legally have a seperate
qdisc per queue in multi-TX-queue setups, and thus get
full parallelization.
