net: ipv4 sysctl option to ignore routes when nexthop link is down
This feature is only enabled with the new per-interface or ipv4 global
sysctls called 'ignore_routes_with_linkdown'.
net.ipv4.conf.all.ignore_routes_with_linkdown = 0
net.ipv4.conf.default.ignore_routes_with_linkdown = 0
net.ipv4.conf.lo.ignore_routes_with_linkdown = 0
...
When the above sysctls are set, will report to userspace that a route is
dead and will no longer resolve to this nexthop when performing a fib
lookup. This will signal to userspace that the route will not be
selected. The signalling of a RTNH_F_DEAD is only passed to userspace
if the sysctl is enabled and link is down. This was done as without it
the netlink listeners would have no idea whether or not a nexthop would
be selected. The kernel only sets RTNH_F_DEAD internally if the
interface has IFF_UP cleared.
With the new sysctl set, the following behavior can be observed
(interface p8p1 is link-down):
default via 10.0.5.2 dev p9p1
10.0.5.0/24 dev p9p1 proto kernel scope link src 10.0.5.15
70.0.0.0/24 dev p7p1 proto kernel scope link src 70.0.0.1
80.0.0.0/24 dev p8p1 proto kernel scope link src 80.0.0.1 dead linkdown
90.0.0.0/24 via 80.0.0.2 dev p8p1 metric 1 dead linkdown
90.0.0.0/24 via 70.0.0.2 dev p7p1 metric 2
90.0.0.1 via 70.0.0.2 dev p7p1 src 70.0.0.1
cache
local 80.0.0.1 dev lo src 80.0.0.1
cache <local>
80.0.0.2 via 10.0.5.2 dev p9p1 src 10.0.5.15
cache
While the route does remain in the table (so it can be modified if
needed rather than being wiped away as it would be if IFF_UP was
cleared), the proper next-hop is chosen automatically when the link is
down. Now interface p8p1 is linked-up:
default via 10.0.5.2 dev p9p1
10.0.5.0/24 dev p9p1 proto kernel scope link src 10.0.5.15
70.0.0.0/24 dev p7p1 proto kernel scope link src 70.0.0.1
80.0.0.0/24 dev p8p1 proto kernel scope link src 80.0.0.1
90.0.0.0/24 via 80.0.0.2 dev p8p1 metric 1
90.0.0.0/24 via 70.0.0.2 dev p7p1 metric 2
192.168.56.0/24 dev p2p1 proto kernel scope link src 192.168.56.2
90.0.0.1 via 80.0.0.2 dev p8p1 src 80.0.0.1
cache
local 80.0.0.1 dev lo src 80.0.0.1
cache <local>
80.0.0.2 dev p8p1 src 80.0.0.1
cache
and the output changes to what one would expect.
If the sysctl is not set, the following output would be expected when
p8p1 is down:
default via 10.0.5.2 dev p9p1
10.0.5.0/24 dev p9p1 proto kernel scope link src 10.0.5.15
70.0.0.0/24 dev p7p1 proto kernel scope link src 70.0.0.1
80.0.0.0/24 dev p8p1 proto kernel scope link src 80.0.0.1 linkdown
90.0.0.0/24 via 80.0.0.2 dev p8p1 metric 1 linkdown
90.0.0.0/24 via 70.0.0.2 dev p7p1 metric 2
Since the dead flag does not appear, there should be no expectation that
the kernel would skip using this route due to link being down.
v2: Split kernel changes into 2 patches, this actually makes a
behavioral change if the sysctl is set. Also took suggestion from Alex
to simplify code by only checking sysctl during fib lookup and
suggestion from Scott to add a per-interface sysctl.
v3: Code clean-ups to make it more readable and efficient as well as a
reverse path check fix.

net: Cavium: Fix MAC address setting in shutdown state
This bug pops up with NetworkManager on Fedora 21. NetworkManager tends to
stop the interface (nicvf_stop() is called) before changing settings. In
stopped state MAC cannot be sent to a PF. However, when the interface is
restarted (nicvf_open() is called), we ping the PF using NIC_MBOX_MSG_READY
message, and the PF replies back with old MAC address, overriding what we
had after MAC setting from userspace. As a result, we cannot set MAC
address using NetworkManager.
This patch introduces special tracking of MAC change in stopped state so
that the correct new MAC address is sent to a PF when interface is reopen.

Add constants and callback functions for the dwmac on rk3368 socs.
As can be seen, the base structure is the same, only registers and

net: stmmac: dwmac-rk: abstract access to mac settings in GRF
The mac settings like RGMII/RMII, speeds etc are done in the so called
"General Register Files", contain numerous other settings as well and
always seem to change between Rockchip SoCs. Therefore abstract the
register accesses into a per-soc ops struct to make this reusable on
other Rockchip SoCs.

net: stmmac: dwmac-rk: Fix clk rate when provided by soc
The first iteration of the dwmac-rk support did access an intermediate
clock directly below the pll selector. This was removed in a subsequent
revision, but the clock and one invocation remained. This results in
the driver trying to set the rate of a non-existent clock when the soc
and not some external source provides the phy clock for RMII phys.
So set the rate of the correct clock and remove the remaining now
completely unused definition.

netfilter: nf_qeueue: Drop queue entries on nf_unregister_hook
Add code to nf_unregister_hook to flush the nf_queue when a hook is
unregistered. This guarantees that the pointer that the nf_queue code
retains into the nf_hook list will remain valid while a packet is
queued.
I tested what would happen if we do not flush queued packets and was
trivially able to obtain the oops below. All that was required was
to stop the nf_queue listening process, to delete all of the nf_tables,
and to awaken the nf_queue listening process.

bpf: BPF based latency tracing
BPF offers another way to generate latency histograms. We attach
kprobes at trace_preempt_off and trace_preempt_on and calculate the
time it takes to from seeing the off/on transition.
The first array is used to store the start time stamp. The key is the
CPU id. The second array stores the log2(time diff). We need to use
static allocation here (array and not hash tables). The kprobes
hooking into trace_preempt_on|off should not calling any dynamic
memory allocation or free path. We need to avoid recursivly
getting called. Besides that, it reduces jitter in the measurement.

bridge: multicast: start querier timer when running user-space stp
When STP is running in user-space and querier is configured, the
querier timer is not started when a port goes to a non-blocking state.
This patch unifies the user- and kernel-space stp multicast port enable
path and enables it in all states different from blocking. Note that when a
port goes in BR_STATE_DISABLED it's not enabled because that is handled
in the beginning of the port list loop.

This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and the

socket, and the required array size is returned in optlen. Hence,
user-space can retry with a properly sized array in case it was too small.

netns updates and a couple of new features for nfnetlink_log and the socket
match that didn't get in time for the previous pull request. More specifically
they are:
1) Add security context information to nfnetlink_queue, from Roman Kubiak.
2) Add support to restore the sk_mark into skb->mark through xt_socket,

3) Force alignment of 16 bytes of per cpu xt_counters, from Eric Dumazet.

5) Move the IPv6 code in br_netfilter into a separated file.
6) Remove unused RCV_SKB_FAIL() in nfnetlink_queue and nfetlink_log, from Eric
Biederman.
7) Two liner to simplify netns logic in em_ipset_match().
8) Add missing includes to net/net_namespace.h to avoid compilation problems
that result from not including linux/netfilter.h in netns headers.
9) Use a forward declaration instead of including linux/proc_fs.h from
netns/netfilter.h
10) Add a new linux/netfilter_defs.h to replace the linux/netfilter.h inclusion
in netns headers.
11) Remove spurious netfilter.h file included in the net tree, also from Eric
