The function memblock_insert_region() is in the section
__init_memblock, also put crashlog_init_memblock there.
This fixes this section mismatch warning:
The function memblock_insert_region.isra.1() references
the function __meminit crashlog_init_memblock().
This is often because memblock_insert_region.isra.1 lacks a __meminit
annotation or the annotation of crashlog_init_memblock is wrong.

All supported kernels require patching ledtrig-netdev in the same way,
so it's safe to just move these changes to the base version of this
driver. We needed these patches for some old kernels 2.6.36 and 3.11.

compat-wireless/backports now contains a bcm47xx_nvram.h file to
backport some of the functions in it which are used by the bcmfmac
driver. This file just checks for the kernel versions and provide an
empty implementations on older kernel versions. This is OK on most
systems, but on bcm47xx / bcm53xx systems we want to call the real
functions here. This commit removes the file from backports in our
build process like we do it with the bcma and ssb header files. Instead
we add a recent version into our kernel so all code uses only one
header file. On bcm47xx / bcm53xx the real implementations of this code
will be used.

This contains two sets of fixes for the 8139cp driver.
For all kernel versions older than 4.3, we can apply the fixes from the
4.3-rc4 kernel. In particular, these fix the TX timeout recovery which
is causing my Geos to lock up until the hardware watchdog kicks in.
For 4.0 and later kernels, we can also apply the additional improvements
which are going into 4.4 to fix and enable hardware checksum/TSO
offload. Backporting those to older kernels is non-trivial.

commit r30917 ("kernel: bypass all netfilter hooks if the sysctls for that
functionality have been disabled - eliminates the overhead of enabling
CONFIG_BRIDGE_NETFILTER in the kernel config") introduced an optimization
which should reduce/eliminate the overhead for traffic send over bridges on
kernels compiled with CONFIG_BRIDGE_NETFILTER=y. But this optimization
breaks the nf_call_iptables per bridge setting which is more fine grained
than the global sysctl net.bridge.bridge-nf-call-iptables setting.
A test reflecting a real world setup was created to identify if this really
eliminates the overhead and if per-bridge nf_call_iptables could be used in
some setups to increase the throughput. A Qualcomm Atheros QCA9558 based
system with one ethernet and an ath9k wifi 3x3 in HT40 mode was used.
Cables from the AP to the wifi station were used to reduce interference
problems during the tests.
The wlan interface was put in one bridge interface called br-wlan. This
bridge usually contains some more wlan interfaces. The eth0 was put in a
second bridge called br-lan. This usually contains some other privileged
wlan or mesh interfaces. Routing was added between br-lan and br-wlan.
Three kernels were tested:
* (default) OpenWrt kernel for this device
* (brfilter-global) OpenWrt kernel with CONFIG_BRIDGE_NETFILTER=y
* (brfilter-local) OpenWrt kernel with CONFIG_BRIDGE_NETFILTER=y and
without 644-bridge_optimize_netfilter_hooks.patch
The changes to the the netfilter settings of the bridge were done via:
* (brfilter-global) /sbin/sysctl -w net.bridge.bridge-nf-call-iptables=1
* (brfilter-lobal) echo 1 > /sys/class/net/br-lan/bridge/nf_call_iptables
and/or echo 1 > /sys/class/net/br-wan/bridge/nf_call_iptables
A station connected to the wlan0 (AP) interface was used to send traffic to
a PC connected via ethernet. iperf with 3 concurrent transmissions was used
to generate the traffic.
| kernel | br-nf-* global | nf-call* iface | download | upload |
|-----------------|----------------|----------------|----------|----------|
| default | 0 | - | 209 | 268 |
| brfilter-global | 0 | - | 185 | 243 |
| brfilter-local | 0 | - | 187 | 243 |
| brfilter-local | 0 | br-lan | 157 | 226 |
| brfilter-local | 0 | br-lan br-wlan | 139 | 161 |
| brfilter-global | 1 | - | 136 | 162 |
Download/upload results in Mibit/s
It can be seen that the patch doesn't eliminate the overhead. It can also
be seen that the throughput of brfilter-global and brfilter-local with
disabled filtering is the roughly the same. Also the throughput for
brfilter-global and brfilter-local for enabled filtering on all bridges is
roughly the same.
But also the brfilter-local throughput is higher when only br-lan requires
the filtering. This setting would not be possible with
644-bridge_optimize_netfilter_hooks.patch applied and thus can only be
compared with brfilter-global and filtering enabled for all interfaces.

Currently, multicast packets from an STA are sent to any according
multicast listener directly through the bridge multicast-to-unicast
feature. Unfortunately, so far this includes the originating STA, too,
resulting in multicast packets being echo'ed back to the originating STA
if it itself is a multicast listener for that group.
This behaviour breaks IPv6 duplicate address detection: An IPv6 Neighbor
Solicitation for IPv6 Duplicate Address Detection is being echo'ed back,
resulting in the host falsely detecting an address collision, which
makes the node unable to claim an IPv6 address and use IPv6 in general.
Mac80211 unfortunately only prevents the echoes for us for multicast
frames. For the multicast frames cast to a unicast destination we'll
need to take care of excluding the originator ourselves.

This reverts commit a080e8e1943156168913d0353a2e99d1151102aa.
It did not fix the problem but just hid some symptom. The real issue was
that IGMP/MLD report suppression was not considered for the
multicast-to-unicast feature. A recent netifd which isolates IGMP/MLD
reports between STAs by utilizing AP-isolation and bridge-hairpinning
should have fixed this.
It is perfectly fine to apply multicast-to-unicast to IPv6 Neighbor
Solicitations, too (once that feature is configured correctly).
