* kernel: fq_codel match flows_cnt to limit sizingKevin Darbyshire-Bryant2016-05-121-2/+4
| | | | | | | | | | | | | | | | | | OpenWRT changed the default fq_codel sch->limit from 10240 to 1024, without also adjusting q->flows_cnt. Eric Dumazet explains below that you must also adjust the buckets (q->flows_cnt) for this not to break. Eric explains: Limit of 1024 packets and 1024 flows is not wise I think. (If all buckets are in use, each bucket has a virtual queue of 1 packet, which is almost the same than having no queue at all) I suggest to have at least 8 packets per bucket, to let Codel have a chance to trigger. So you could either reduce number of buckets to 128 (if memory is tight), or increase limit to 8192. flows_cnt is now set to 1024/8=128 Signed-off-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk>

* kernel: fix section mismatch in crashlogHauke Mehrtens2016-03-051-1/+1
| | | | | | | | | | | | | | | 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.

* kernel: take bcm47xx_nvram.h from kernel and not backportsHauke Mehrtens2015-11-133-16/+38
| | | | | | | | | | | | | | | | | | 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.

* generic: Fix per interface nf_call_iptables settingFelix Fietkau2015-09-091-179/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
