17) Set a more appropriate sk_pacing_rate for non-TCP sockets, otherwise
    FQ packet scheduler does not pace those flows properly.  Also from
    Eric Dumazet.

18) rtlwifi miscalculates packet pointers, from Mark Cave-Ayland.

19) l2tp_xmit_skb() can be called from process context, not just softirq

    doing two full packet xmit paths at the same time when emitting
    neighbour discovery messages.  From Hannes Frederic Sowa.

454594f3b9 Revert "bridge: only expire the mdb entry when query is received"
While this commit was a good attempt to fix issues occuring when no
multicast querier is present, this commit still has two more issues:

1) There are cases where mdb entries do not expire even if there is a
querier present. The bridge will unnecessarily continue flooding
multicast packets on the according ports.

2) Never removing an mdb entry could be exploited for a Denial of
Service by an attacker on the local link, slowly, but steadily eating up
all memory.

Actually, this commit became obsolete with
"bridge: disable snooping if there is no querier" (b00589af3b)
which included fixes for a few more cases.

Therefore reverting the following commits (the commit stated in the
commit message plus three of its follow up fixes):

====================
Revert "bridge: update mdb expiration timer upon reports."
This reverts commit f144febd93.
Revert "bridge: do not call setup_timer() multiple times"
This reverts commit 1faabf2aab.
Revert "bridge: fix some kernel warning in multicast timer"
This reverts commit c7e8e8a8f7.
Revert "bridge: only expire the mdb entry when query is received"
This reverts commit 9f00b2e7cf.

Do not touch keyboard backlight unless explicitly passed a module
parameter.  In this way we won't make wrong assumptions about what are
good default values since they actually are different from model to
model.

The only side effect is that we won't know what is the current value
until set via the sysfs attributes.

02cf4ebd82 tcp: initialize passive-side sk_pacing_rate after 3WHS
For passive TCP connections, upon receiving the ACK that completes the
3WHS, make sure we set our pacing rate after we get our first RTT
sample.

On passive TCP connections, when we receive the ACK completing the
3WHS we do not take an RTT sample in tcp_ack(), but rather in
tcp_synack_rtt_meas(). So upon receiving the ACK that completes the
3WHS, tcp_ack() leaves sk_pacing_rate at its initial value.

Originally the initial sk_pacing_rate value was 0, so passive-side
connections defaulted to sysctl_tcp_min_tso_segs (2 segs) in skbuffs
made in the first RTT. With a default initial cwnd of 10 packets, this
happened to be correct for RTTs 5ms or bigger, so it was hard to
see problems in WAN or emulated WAN testing.

Since 7eec4174ff ("pkt_sched: fq: fix non TCP flows pacing"), the
initial sk_pacing_rate is 0xffffffff. So after that change, passive
TCP connections were keeping this value (and using large numbers of
segments per skbuff) until receiving an ACK for data.

d69e0f7ea9 davinci_emac.c: Fix IFF_ALLMULTI setup
When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't,
emac_dev_mcast_set should only enable RX of multicasts and reset
MACHASH registers.

It does this, but afterwards it either sets up multicast MACs
filtering or disables RX of multicasts and resets MACHASH registers
again, rendering IFF_ALLMULTI flag useless.

This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and
disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set.

Tested with kernel 2.6.37.

c2f17e827b ipv6: probe routes asynchronous in rt6_probe
Routes need to be probed asynchronous otherwise the call stack gets
exhausted when the kernel attemps to deliver another skb inline, like
e.g. xt_TEE does, and we probe at the same time.

We update neigh->updated still at once, otherwise we would send to
many probes.

3a70417c1d Merge branch 'rt6i_gateway'
Julian Anastasov says:

====================
ipv6: use rt6i_gateway as nexthop

	The following patchset makes sure that rt6i_gateway
contains valid nexthop information in all cases, so that
we can use different nexthop for sending.

	The first patch is a simple fix that makes IPVS, TEE,
RAW(hdrincl) and RTF_DYNAMIC(without RTF_GATEWAY) work as
before 3.9. There is a single corner case not solved by
this patch: RAW(hdrincl) or TEE using local address for
nexthop, a silly feature, I guess. In this case we
see zeroes in rt6i_gateway because we get route that is not
cloned. This is solved only with patch 2.

	The second patch is an optimization that makes sure
all resulting routes have rt6i_gateway filled, so that we
can avoid the complex ipv6_addr_any() call added to rt6_nexthop()
by patch 1. And it sets rt6i_gateway for local routes, a case
not handled by patch 1.

	The third patch uses the new rt6_nexthop() function to fix
the matching of gateways in the same way as commit bbb5823cf7
("netfilter: nf_conntrack: fix rt_gateway checks for H.323 helper")
fixes nf_conntrack_h323_main.c for IPv4. Currently, it depends on
the new definition of rt6_nexthop() in patch 2. Actually, if
patch 2 is applied, patch 3 becomes a cosmetic change.

	I see the following two alternatives for applying these
patches:

1. Linger patch 2 in net-next to avoid surprises in the upcoming
release. In this case patch 3 can be reworked not to depend on
the new rt6_nexthop() definition in patch 2. I guess this is a
better option, so that patch 2 can be reviewed and tested for
longer time.

2. Include all 3 patches in net tree - more risky because this
is my first attempt to change IPv6.

	Here is the situation as handled by patch 2:

	In IPv6 the resolved routes are always host routes (/128
with DST_HOST), mostly cloned ones. We allow routes in FIB
to contain rt6i_gateway with zeroes (eg. for local subnets) but
on cloning we can fill the rt6i_gateway field in result.
This works even without this patchset.

	There is a single special case where dst is provided as
skb_dst directly without a routing call: icmp6_dst_alloc(). It is a
private dst allocated just for the particular ICMP packet. Patch 2
fills rt6i_gateway in this case, needed for the new rt6_nexthop()
simplification.

	The last case is addrconf_dst_alloc(), it can put in
FIB local/anycast routes when addresses are added. Patch 2
needs to fill rt6i_gateway in this case because such routes
are returned without cloning.

Make sure rt6i_gateway contains nexthop information in
all routes returned from lookup or when routes are directly
attached to skb for generated ICMP packets.

The effect of this patch should be a faster version of
rt6_nexthop() and the consideration of local addresses as
nexthop.

96dc809514 ipv6: always prefer rt6i_gateway if present
In v3.9 6fd6ce2056 ("ipv6: Do not depend on rt->n in
ip6_finish_output2()." changed the behaviour of ip6_finish_output2()
such that the recently introduced rt6_nexthop() is used
instead of an assigned neighbor.

As rt6_nexthop() prefers rt6i_gateway only for gatewayed
routes this causes a problem for users like IPVS, xt_TEE and
RAW(hdrincl) if they want to use different address for routing
compared to the destination address.

Another case is when redirect can create RTF_DYNAMIC
route without RTF_GATEWAY flag, we ignore the rt6i_gateway
in rt6_nexthop().

Fix the above problems by considering the rt6i_gateway if
present, so that traffic routed to address on local subnet is
not wrongly diverted to the destination address.

Thanks to Simon Horman and Phil Oester for spotting the
problematic commit.

Thanks to Hannes Frederic Sowa for his review and help in testing.

4293b9f57a bnx2x: Don't pretend during register dump
As part of a register dump, the interface pretends to have the identity
of other interfaces of the same physical device in order to perform
HW configuration for them - specifically, it needs to prevent attentions
from generating on those functions as the register dump accesses registers
in common blocks which whose reading might generate an attention.

However, such pretension is unsafe - unlike other flows in which the driver
uses pretend, during register dump there is no guarantee no other HW access
will take place (by other flows). If such access will take place, the HW will
be accessed by the wrong interface, and leave both functions in an incorrect
state.

This patch removes all pretensions from the register dump flow. Instead, it
changes initial configuration of attentions such that no fatal attention will
be generated for other functions as a result of the register dump
(notice however, a debug print claiming an attention from other functions IS
possible during the register dump)

32316a46f2 bnx2x: Lock DMAE when used by statistic flow
bnx2x has several clients to its DMAE machines - all of them with the exception
of the statistics flow used the same locking mechanisms to synchronize the DMAE
machines' usage.

Since statistics (which are periodically entered) use DMAE without taking the
locks, they may erase the commands which were previously set -
e.g., it may cause a VF to timeout while waiting for a PF answer on the VF-PF
channel as that command header would have been overwritten by the statistics'
header.

This patch makes certain that all flows utilizing DMAE will use the same
API, assuring that the locking scheme will be kept by all said flows.

1a6974b2c7 bnx2x: Prevent an illegal pointer dereference during panic
During a panic, the driver tries to print the Management FW buffer of recent
commands. To do so, the driver reads the address of that buffer from a known
address. If the buffer is unavailable (e.g., PCI reads don't work, MCP is
failing, etc.), the driver will try to access the address it has read, possibly
causing a kernel panic.

This check 'sanitizes' the access, validating the read value is indeed a valid
address inside the management FW's buffers.
The patch also removes a read outside the scope of the buffer, which resulted
in some unrelated chraracters appearing in the log.

sendto len<mtu flag MSG_MORE
sendto len>mtu flag 0
The skb is not treated as fragmented one because it is not initialized
that way. So move the initialization to fix this.

e36d3ff911 udp6: respect IPV6_DONTFRAG sockopt in case there are pending frames
if up->pending != 0 dontfrag is left with default value -1. That
causes that application that do:
sendto len>mtu flag MSG_MORE
sendto len>mtu flag 0
will receive EMSGSIZE errno as the result of the second sendto.

This patch fixes it by respecting IPV6_DONTFRAG socket option.

f2e5ddcc0d net: fix cipso packet validation when !NETLABEL
When CONFIG_NETLABEL is disabled, the cipso_v4_validate() function could loop
forever in the main loop if opt[opt_iter +1] == 0, this will causing a kernel
crash in an SMP system, since the CPU executing this function will
stall /not respond to IPIs.

This problem can be reproduced by running the IP Stack Integrity Checker
(http://isic.sourceforge.net) using the following command on a Linux machine
connected to DUT:

"icmpsic -s rand -d <DUT IP address> -r 123456"
wait (1-2 min)

90c6bd34f8 net: unix: inherit SOCK_PASS{CRED, SEC} flags from socket to fix race
In the case of credentials passing in unix stream sockets (dgram
sockets seem not affected), we get a rather sparse race after
commit 16e5726 ("af_unix: dont send SCM_CREDENTIALS by default").

We have a stream server on receiver side that requests credential
passing from senders (e.g. nc -U). Since we need to set SO_PASSCRED
on each spawned/accepted socket on server side to 1 first (as it's
not inherited), it can happen that in the time between accept() and
setsockopt() we get interrupted, the sender is being scheduled and
continues with passing data to our receiver. At that time SO_PASSCRED
is neither set on sender nor receiver side, hence in cmsg's
SCM_CREDENTIALS we get eventually pid:0, uid:65534, gid:65534
(== overflow{u,g}id) instead of what we actually would like to see.

On the sender side, here nc -U, the tests in maybe_add_creds()
invoked through unix_stream_sendmsg() would fail, as at that exact
time, as mentioned, the sender has neither SO_PASSCRED on his side
nor sees it on the server side, and we have a valid 'other' socket
in place. Thus, sender believes it would just look like a normal
connection, not needing/requesting SO_PASSCRED at that time.

As reverting 16e5726 would not be an option due to the significant
performance regression reported when having creds always passed,
one way/trade-off to prevent that would be to set SO_PASSCRED on
the listener socket and allow inheriting these flags to the spawned
socket on server side in accept(). It seems also logical to do so
if we'd tell the listener socket to pass those flags onwards, and
would fix the race.

Before, strace:

recvmsg(4, {msg_name(0)=NULL, msg_iov(1)=[{"blub\n", 4096}],
        msg_controllen=32, {cmsg_len=28, cmsg_level=SOL_SOCKET,
        cmsg_type=SCM_CREDENTIALS{pid=0, uid=65534, gid=65534}},
        msg_flags=0}, 0) = 5

After, strace:

recvmsg(4, {msg_name(0)=NULL, msg_iov(1)=[{"blub\n", 4096}],
        msg_controllen=32, {cmsg_len=28, cmsg_level=SOL_SOCKET,
        cmsg_type=SCM_CREDENTIALS{pid=11580, uid=1000, gid=1000}},
        msg_flags=0}, 0) = 5

This reverts commit 320c90be7b.

Christoph Hellwig <hch@infradead.org> commented:
This one shouldn't go in - Geert sent it a bit prematurely, as Lustre
shouldn't use it just to reimplement core VM functionality (which it
shouldn't use either, but that's a separate story).
