[David Miller <davem@davemloft.net>]

Lots of tiny fixes, pretty much everywhere.  Nothing really stands out, but
each bug is certainly a bummer if you happen to run into it.

I hope all the PMTU and redirect regressions I added to the ipv4 code
are really fixed now :-)  A huge thanks to Steffen Klassert, Eric Dumazet,
and others for helping to resolve these problems.

The netfilter ADVANCED depency adjustments are, of course, in here too.

1) ARCNET and PHYLIB were inadvertantly changed to bool, revert back to
   tristate.  From Ben Hutchings.

2) Two netfilter ADVANCED adjustments.

3) Cached route lookups must validate referenced inetpeer.

4) Revert old udp_recvmsg() 'redundant variable' change, because in fact
   the 'copied' variable was not redundant and this broke things when
   encountering UDP packets with bad checksums.

5) TCP ipv6 input packet processing could crash under various
   circumstances in error paths, fixes from Eric Dumazet.

6) Fix bad decnet socket refcounting, also from Eric Dumazet.

7) L2TP needs to validate attached socket route, fix from Florian Westphal.

8) Proxy ARP entries listed improperly in network namespace, fix from
   Jorge Boncompte.

9) IGMP's ip_mc_add_src() incorrectly decrements the entry refcount,
   fix from Jun Zhao.

10) bnx2x LED handling fix from Yaniv Rosner.

11) TX descriptor list was mis-sized in qlge driver, fix from Thadeu
    Lima de Souza Cascardo.

12) ehea per-TX-queue memory consumption was enormous, scale it
    down to be more reasonable, from Anton Blanchard.

13) We have to adjust the IP header ->daddr in ip_forward_options()
    not ip_options_rcv_srr() as the latter is too early.  Fix from
    Li Wei.

14) Netlabel adds to ipv4 map list in ipv6 code :-)  Fix from
    Dan Carpenter.

15) Several MTU handling regression fixes in ipv4 from Steffen Klassert.

16) DM9000 driver tests bit using && instead of &.  Fix from Mark Brown.

17) Concurrent stream socket reads may cause poll() to incorrectly block
    for AF_UNIX sockets, report and fix from Alexey Moiseytsev.

18) Invalidate cached ipv4 redirects properly, fix from Eric Dumazet.

19) Some 802.11 netlink attributes were not being validated properly,
    fix from Eliad Peller.

20) Wireless TX aggregation accidental double-stop fix from Johannes Berg.

21) rtlwifi can deadlock on lps_lock, fix from Stanislaw Gruszka.

22) /proc/*/net/dev_mcast output corruption fix from Anton Blanchard.

23) "-1" means default for multicast hops in ipv6, fix from Li Wei.

24) Integer overflow fix in SCTP from Xi Wang, although it took me two
    tries to get it committed properly, my bad.

25) ISDN string NULL termination fixes from Dan Carpenter.

26) TEQL driver needs to perform dst_get_neighbour() under proper
    RCU protection, fix from Eric Dumazet.

27) Likewise, fix a similar lockdep splat in rt_cache_seq_show, also
    from Eric Dumazet.

28) When the PSCHED_SHIFT was adjusted from 10 to 6 the RED packet scheduler did
    not have it's idle period handling adjusted properly.  Fix from Eric Dumazet.
    
29) When bridge user-stp mode is used, we can get the device stuck in no-carrier
    state forever.  Fix from Vitalii Demianets.

30) When the RED packet scheduler was made classful, we didn't update the test
    for queue empty.  It must check q->qdisc->q.len not whether sch->q is empty.
    Fix from Eric Dumazet.

31) Missing spin_lock_init() and workqueue deadlock fix in p54spi driver from
    Michael Buesch.

32) ip_route_me_harder() in netfilter needs to use HH_DATA_ALIGN when expanding
    the SKB header area, otherwise packet headers become misaligned.  Fix
    from Paul Guo.

33) iseries_veth uses wrong length argument to memset() call, from Thomas Jarosch.

34) When DCCP ipv4 connect fails to lookup a route, we don't record the error
    from the 'rt' error pointer properly, fix from RongQing Li.

35) Fix namespace based OOPS in nf_conntrack by making event callback
    registration per-ns.  Fix from Pablo Neira Ayuso.

36) In netlink socket dumps, report the TOS attribute of inet sockets,
    regardless of whether they are ipv4 or ipv6, because this value
    has meaning for ipv4 mapped ipv6 connections.  Fix from Maciej
    Żenczykowski.

37) ndisc_send_redirect() has reversed rate limiting check, oops.  Fix from
    Li Wei.

38) B44 needs to use dev_kfree_skb_irq() when releasing TX buffers because
    the free runs with an IRQ safe spinlock held, fix from Xander Hover.

39) If we reuse a TCP time-wait socket in ipv6, we erroneously drop the SYN
    because treq->iif is not set early enough in tcp_v6_conn_request().  Fix
    from Eric Dumazet.  This was largely not noticed because 1 second later the
    client would resend the SYN and that would work since the first SYN
    killed off the time-wait entry.

40) Fix PHY initialization in jme driver, from Aries Lee.

Please pull, thanks a lot.
