08.05.20203073KernelBug ReportLowHighAR8337/AR8327 Flow Control Enabled on Archer C7 v5 (and...TrunkUnconfirmed Task Description

I have a TP-Link Archer C7 v5 (ath79/generic) running OpenWrt 19.07.2 r10947-65030d81f3 and periodically one of my hosts sends out a long-running flood (10/sec) of MPCP Pause frames. The AR8337 switch is configured to honor these frames on port 0 (CPU), and other ports, so stops switching frames essentially forever.

There is no way exposed to user to disable flow control.

Flow control should be turned off unless explicitly requested by the user (e.g., they are in a Datacenter/Enterprise environment and/or doing Fibre Channel over Ethernet). This is exactly the opposite of how it currently is with the added benefit that the user cannot change the behavior.

Here’s a tool that will helpfully generate MPCP Pause frames:
https://github.com/nwholloway/mpcp

You can use this to bring down your network indefinitely. Additionally, since the AR8337 switch consumes these frames you will not be able to see them from the OpenWRT host.

24.08.2016115Base systemBug ReportVery LowMediumWWAN-connections using 3g with HUAWEI ME909u-521 unstab...TrunkUnconfirmed Task Description

Actually, I am trying to stabilize wwan (3g actually; LTE later on) using pppd with my HUAWEI ME909u-521,
because either my MT7620-based router locks up during boot already; or after short period of real usage.
During night, when router is almost idle, just some watchdog date sent via wwan, no problem.

First trace of a possible problem was this msg in logread:
daemon.notice netifd: wwan (1676): Error setting WWAN mode!

Wich is expected, as in /lib/netifd/proto/3g.sh:

...

                      elif echo "$cardinfo" | grep -qi huawei; then
                              case "$service" in
                                      umts_only) CODE="14,2";;
                                      gprs_only) CODE="13,1";;
                                      *) CODE="2,2";;
                              esac
                              export MODE="AT^SYSCFG=${CODE},3FFFFFFF,2,4"    #####Will not work !!!!! Switching USB-Stick to 3g-preferred ?

...
...

                      [ -n "$MODE" ] && gcom -d "$device" -s /etc/gcom/setmode.gcom

Will not work, because the ME909u-521 rejects AT^SYSCFG . However, AT^SYSCFGEX will work, but having different syntax.
MODE=”AT^SYSCFG=${CODE},3FFFFFFF,2,4” will be effective for simpler modems.

/etc/gcom/setmode.gcom returns exit 1; but this error is not checked in 3g.sh

Not shure, whether this is the reason for my problems; however, reason of concern, as high speed modems
are more and more common.
Willing to participate in testing/debugging.

With LEDE version reboot-1444-g1bb914d, when pulling data through the WAN interface to the LAN interface at a sufficiently high speed, e.g. on a Raspberry Pi connected by ethernet to a LAN port, and the WAN interface connected to a gigabit internet service and issuing a command like:

curl https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.7.2.tar.xz > /dev/null

From the pi, I see something like:

Where the “link down” is the WGT634U panic’ing and rebooting. The panic on the WGT634U looks like this:

07.09.2016162Base systemBug ReportVery LowLowTwo issues with libuclient-openssl in luci-sslTrunkUnconfirmed Task Description

1: RC4 and 3DES are used when both have security issues. Actually the latter also is true of mbedtls/polarssl.

2: Only TLS 1.2 is supported. This makes multiple clients unable to connect.

BTW, I got this working after modifying the Makefile to luci-ssl to depend on libustream-openssl instead. No idea what the situation is but so far it works without a problem.

Hello,

As I said, if I change the TX power from 0 dBm to 20 dBm doesn’t nothing. There isn’t any visible change in tx power. I tested other powers too (5, 8, 15,..).

It is a Xiaomi Nano (lite).

12.10.2016222Base systemFeature RequestVery LowLowproviding pre-built images for extroot for devices with...TrunkUnconfirmed Task Description

Currently, the only way to be able to make extroot (use an external drive as overlay) for 4MiB devices is to build an image with the Image Builder as they can’t fit the packages needed in the jffs.

For most linux users this isn’t a major issue as the Image Builder runs on Linux and with a couple commands you build all, but it’s still time-consuming.

For everyone else this is an issue, as they need to get a linux system, learn how to use the Image Builder, and so on.

I’m asking if it is possible to make pre-built images with the right packages to allow extroot on 4 MiB devices.

The packages I thing we need in these pre-built images are all is needed by the device to be able to format and check its own drive, because again most users don’t have access to a linux system to format a drive with ext4 or whatever.

It seems e2fsprogs is too big to fit with the other packages required, currently only f2fs filesystem tools are split and can be used in 4MiB devices for extroot.

These are the packages that currently should allow building an extrootable image that fits on 4MiB storage:

blkid block-mount kmod-fs-f2fs kmod-usb-storage kmod-usb-uhci kmod-usb-ohci mkf2fs f2fsck

(of course no luci is included).

21.11.2016296Base systemBug ReportVery LowHighUbiquiti Bullet M 10/100 ethernet interface comes up as...TrunkUnconfirmed Task Description

For the last month or so, and persisting in r2248, when a Ubiquiti Bullet M is booted through typical Ubiquiti 10/100 passive PoE injector, the interface appears to come up in gigabit mode (see timestamp 18.990274 below), despite being only a 10/100 Mbps interface. Restarting /etc/init.d/network fixes it. I am running batman-adv over the ethernet interface, which may be involved. I will check if it happens when batman-adv is not used on the interface and report in a followup comment.

The dmesg look like this:

29.11.2016315Base systemFeature RequestVery LowMediumImprove sysupgrade (CLI) on dual-partition routersTrunkUnconfirmed Task Description

Some of the recent Linksys (maybe other) routers have two partitions: WRT1900, EA8500, etc.

Would be great if when running sysupgrade on those routers it did NOT kill all active processes and kept the router working while writing an image to the inactive partition.

Would also be great if there was an option to prevent automatic reboot after writing an image.

Ultimate goal is to have an upgrade process where current working state is uninterrupted and only when you reboot – you boot into new image.

03.12.2016320Base systemFeature RequestVery LowLowrelayd feature requestTrunkUnconfirmed Task Description

I found a couple of bugs with relayd based bridge configuration and I would like to suggest a feature request. Will fill one entry per issue:

On today’s trunk

3- in a configuration where the network attached to the wireless radio is configured via DHCP, the listening interface is not set up automatically. DD-WRT and Gargoyle do this automatically ( they overwrite the config/network file with the gateway parameter and reload relayd.

 


09.12.2016329Base systemBug ReportVery LowLowAR9341 needs analog switch resetTrunkUnconfirmed Task Description

This is a bug report for the AR9341 SOC on LEDE trunk reboot-2445-gee5a6c1.

I have builded a custom firmware for a unsupported device based on the Atheros DB120 reference board.

The analog port of the ethernet switch needs to be resetted before it can operate.

Part of bootlog without analog reset:

[    2.179262] ag71xx-mdio.1: unknown phy id 'ffff:ffff'

Br-lan is not intialized due no analog switch reset.

Part of bootlog with analog reset:

[    2.059037] ag71xx-mdio.1: Found an AR934X built-in switch

And br-lan is initialized and networking is working fine.

A reset is performed by the function ath79_register_eth (defined in dev-eth.c):

ath79_device_reset_set(AR934X_RESET_ETH_SWITCH);
ath79_device_reset_clear(AR934X_RESET_ETH_SWITCH);

However, no analog reset is performed, for example:

ath79_device_reset_set(AR934X_RESET_ETH_SWITCH);
ath79_device_reset_clear(AR934X_RESET_ETH_SWITCH);

ath79_device_reset_set(AR934X_RESET_ETH_SWITCH_ANALOG);
ath79_device_reset_clear(AR934X_RESET_ETH_SWITCH_ANALOG);

Omitting the analog reset does not break the DB120 builds because the analog reset is already performed by ar934x_nfc_hw_reset in dev-nfc.c.

An easy fix is to do a analog reset in the device’s mach file. However, for the sake of consistency and autism, the reset should be performed by ath79_register_eth in dev_eth.c and not by ar934x_nfc_hw_reset in dev_nfc.c. My AR9341 device doesn’t even use a NAND flash.

15.01.2017389Base systemBug ReportVery LowLowodhcpd relay mode is blocked by firewall by defaultTrunkUnconfirmed Task Description

odhcpd currently won’t work when put in relay mode if followed the manual naively. Turns out this is because firewall blocks incoming traffic to DHCPv6 server (port 547) from external DHCPv6 servers (port 547) from WAN zone by default. It may be a good idea to allow this out of the box, though I’m unsure if there are any security complications from this – I’m a newcomer to IPv6. Replies come with the source global IPv6 address of DHCPv6 server to the global IPv6 address of the router, so it’s difficult to make a more constrained rule without hardcoding them or at least the prefix.

Example rule which fixes relay mode:

config rule
	option enabled '1'
	option target 'ACCEPT'
	option src 'wan'
	option proto 'udp'
	option dest_port '547'
	option name 'Allow DHCPv6 Relay'
	option family 'ipv6'
	option src_port '547'

I have an ISP that requires PPPoE on vlan 201 with 802.1Q tags (CenturyLink fiber). On OpenWRT 15.05.1 and on earlier versions of LEDE (not sure about an exact revision, but maybe October/November timeframe) I could simply define my wan interface in /etc/config/network like this and it just worked:

```
config interface ‘wan’

  option ifname 'eth0.201'
  option proto 'pppoe'
  option username 'user@provider'
  option password 'password'

```

I can’t find any way to make this work on recent versions of LEDE. I’ve tried new builds at least every few weeks, but none have worked for the past few months. I’ve tried configuring the switch_vlan section by adding a ‘t’ after the appropriate switch port to enable tagging, I’ve tried defining a new interface and then using that as the wan ifname, and I’ve tried the command line `ip link` and `ppp` invocations that work on every other linux system I’ve tried, but I can’t find anything that works on recent versions of LEDE.

On other linux systems I can do roughly the following and it works:

```
ip link add link eth0 name eth0.201 type vlan id 201
ip link set eth0.201 up
pppd call centurylink
```

where /etc/ppp/peers/centurylink and /etc/ppp/chap-secrets looks like this:
```
> cat /etc/ppp/peers/centurylink
plugin rp-pppoe.so

eth0.201
name “user@provider” usepeerdns
persist
defaultroute
hide-password
noauth

cat /etc/ppp/chap-secrets
#USERNAME PROVIDER PASSWORD IPADDRESS
user@provider * password
```

I’ve tried using tcpdump to capture what’s happening and on other systems (Ubuntu 16.10, Debian Jessie, pfsense) I see an 802.1Q tag, but I don’t see that on LEDE. That might be expected though because it seems totally possible that the switch itself is doing the 802.1Q stuff and tcpdump doesn’t see the actual packets sent over the wire. I have no idea if that’s the case, though. I guess I could also try this on OpenWRT as well, but I haven’t taken the time to do that yet.

The only other difference I’ve seen is that by default LEDE doesn’t send a Host-Uniq tag, but even if I set the host_uniq uci config it doesn’t fix things. Regardless of what I do I see logs that look like this:

      option netmask '255.255.255.0'

```

Interestingly, OpenWRT has exactly the same version of ppp and rp-pppoe (2.4.7 and 3.8p, respectively) so it seems like there’s something else in play and my guess is it’s related to vlan tagging, but I don’t seem to have the same issue as FS#227 which mentions both PPPoE and vlan config, but it is quite difficult to follow the discussion there so maybe I’m missing something.

17.01.2017398PackagesFeature RequestVery LowLowodhcpd: add UCI option to insert DHCP fill for missing ...TrunkUnconfirmed Task Description

This is a request for a common DHCP function found in other software. It would be nice for an odhcpd general option to enable it to fill in unnamed leases. DHCPv4 use the MAC as in unknown-010203040506 and DHCPv6 use the last 64 bits of the DUID as in unknown-0102030405060708. This can be used to figure out which device has failed to send its host name. This is a common problem with DHCPv6. This is a common problem for smart TV or cameras. Consider logs from a device other than the DHCP serving router. Consider where IT may not want to static assign 100’s of host names for display devices over a large work site or campus. Security logs and DHCP logs on a distributed network can then be reconciled a-synchronously, off line, or only when an investigation is required.

18.01.2017400PackagesBug ReportVery LowLowodhcpd: lease file persistence per RFC2131 S-2.1 and S-...TrunkUnconfirmed Task Description

RFC2131 DHCPv4 expects that the DHCP leases and other configuration results are in persistent storage. For small embedded routers during a machine reboot, it has been accepted that read-write memory is RAM (not flash) and persistence may not be entirely upheld. That being said, odhcpd has no means to maintain the lease information even through an application only restart (example ifup event). The lease file odhcpd writes is not used to seed odhcpd, if it is restarted. (1) an interface reconnect that causes odhcpd to restart destroys the lease record, even if the network resumes as previously configured. (2) even if odhcpd lease file is directed to persistent storage (USB drive) it is not used to resume leases.

18.01.2017401PackagesFeature RequestVery LowLowodhcpd: lease trigger script receives no argumentsTrunkUnconfirmed Task Description

when odhcpd calls the “lease trigger” script it does not pass any arguments to the script. The reason for the trigger and the host involved in the trigger are not shared. There is no discretion for RENEW, REBIND, CONFIRM, or RELEASE. Scripts which wish to load DNS with limited data, need to store their own copy of DHCP lease file and do differences. Otherwise a raw translate and dump of a large DHCP network could cause a lot of congestion as DHCP clients come on line. Reseting a network can cause an “in rush” flow like air conditioning loads on a power grid during a summer power outage.
This is exacerbated if the DNS is served on a separate device over the network, such as nsd and nsd-control (bind or unbound also). It would be good to at least pass the command and parameters common to a odhcpd lease file line.

18.01.2017403PackagesFeature RequestVery LowLowodhcpd: expand the capability of DHCPv6 HOSTID assignem...TrunkUnconfirmed Task Description

It would be nice to assign the HOSTID range or bit width as an option. odhcpd just assigns ::0100~::0FFF without any options. It would be nice to be able to use all 64 bits. With this, also it would be nice to add a random seed and seed time as options. This way the DUID hash-to-HOSTID could be rotated. In this way, SLAAC privacy addresses could be replicated with STATEFUL DHCP control and well known hostnames. This would support high-accountability networks like Universities and other large organizations.

It would be a counter to Google’s lack of “interest” in supporting DHCPv6. This would provide DHCPv6 privacy addresses.

18.01.2017406Base systemFeature RequestVery LowLowodhcpd: enable IPv6 unicast relayTrunkUnconfirmed Task Description

We want to use Prefix Delegation in a large layer3 mesh network. Currently odhcpd only supports DHCPv6-Relay by forwarding the incoming request to the master interface with multicast all-routers-destination address.

In a mesh network we do not have master/uplink interfaces. But we have the IP of the DHCP server which is X hops away and the routing protocol knows which way to send the packet.

Is it possible to add dhcp relay via unicast? An additional config parameter for the IP of the DHCP server is then also needed.

24.01.2017427Base systemBug ReportVery LowMediumSwitch broken with WRT3200ACM (removes wifi adapters an...TrunkUnconfirmed Task Description

- Device problem occurs on:

WRT3200ACM

- Software versions of LEDE release, packages, etc.:

master tree (and v17.01), bisected to f24ffb901e0408917748773b883841eca52eea05.

- Steps to reproduce

* Flash a recent LEDE snapshot on the WRT3200ACM (and factory reset),
* enable wifi (2 or 5 Gz) → Wifi works
* disable wifi → errors in the dmesg about not being able to set a feature (can’t remember the exact error)
* re-enable wifi → errors in the dmesg saying that the adapter does not exist. This gets shouted in the dmesg every 5 seconds

A reboot doesn’t fix the issue. I need to downgrade the firmware prior to f24ffb901e0408917748773b883841eca52eea05 and factory reset to get the wifi adapters back.

For the Vlan bridge, symptoms are easier to detect:
* create a new adapter bridged on eth0.100 eth1.100
* no traffic goes through it. An snapshot before f24ffb901 used to work
(the setup is the Free french provider which has a vlan between the modem and the TV adapter over VLAN 100. So the LEDE box should act like a pass-through here only)

I bisected to the commit mentioned above (which, to me seems suspicious given that the driver is for mvsw61xx and the switch in the WRT3200ACM is MV88E6352, so a different generation). I don’t have enough knowledge of the chip to understand why this fails, but I don’t feel confident enough to simply send a PR with the revert.

Reverting f24ffb901e on top of master makes the Wifi and VLAN back to normal.

01.02.2017449Base systemBug ReportVery LowLowrelayd can cause dropped packets if client has /proc/sy...TrunkUnconfirmed Task Description

DEVICE: N/A (can be reproduced on any system running relayd)
LEDE version: N/A (can be reproduced on a VM running debian with relayd installed)

Steps to reproduce:

* Run relayd on a system (aka router)with two interfaces.
* Run a stock Ubuntu-16.04 system (aka client) connected to the managed interface.
* Run another system (aka server) on the other interface of relayd system.
* Have server ping client and watch connectivity drop out periodically.
* Have client ping server and watch connectivity drop out periodically.

Our fix for the problem need two changes:

* Add arptables rules to system to handle kernel level arp requests properly via mangling the source address in the arp requests
* Modify relayd to send the correct src addr in the arp requests that it generates.

Our changes to relayd are here:

* https://github.com/troth/relayd/commit/c8d895ee71be59262f01c3fdf50f307ebf1593e7

From commit message for my fix:

    Add option to set arp src addr for managed interfaces.
    
    Relayd will send arp requests out a managed interface like this:
    
        Who has 192.168.1.40, tell 192.168.2.1
    
    In most cases, this works, but some clients will not send a reply (on
    linux, client will not reply if /proc/sys/net/ipv4/conf/*/rp_filter is
    set to 1, which happens to be the default on ubuntu-16.04).
    
    Add '-s' option to tell relayd to use the specified addr as the arp src
    addr for managed interfaces. The arp requests would then look like:
    
        Who has 192.168.1.40, tell 192.168.1.100
    
    for which the client properly sends a reply.
    
    The symptoms of the problem manifest as dropped packets due to the
    kernel marking the arp entry for the client as FAILED due to lack of
    responses to the arp requests. Eventually (10-30 seconds later), the arp
    table is updated and connectivity is restored.
04.02.2017461Base systemBug ReportVery LowMediumMass Cascade of DHCP ULA Prefix Assignments with DHCP-P...AllUnconfirmed Task Description

Here is one that gets a bit ugly. Lets say we chain a bunch of LEDE based routers together. Lets also enable a nice numbering system in IP4 and IP6. Lets enable DHCP-PD through the network, because our ISP was generous with a /56. The IP4 is only static and is easy to control, see table below. Its tedious, but easy. The problem is in parallel the IP6 addresses compound in the ULA region. Each router DHCP-PD the ULA above it, and gets its own ULA from Global settings in Network UCI. There seems no easy way to control this mass cascade of ULA, and get good fail over.

Ideal Requirements:
(1) If router above is unavailable, then next tier router uses ULA (network global UCI) to begin assigning addresses to clients and subnets.
(2) If router above is available, then next tier router expires its self-generated ULA and subnets, and gets ULA from delegation above to then re-delegate to subnets.
(*) Bonus: make some parts optional

04.02.2017463Base systemBug ReportVery LowLowup/down on a usbnet interfaces fails to reassign ULA ad...TrunkUnconfirmed Task Description

Supply the following if possible:
- Device problem occurs on: anything running usbnet
- Software versions of LEDE release, packages, etc: head
- Steps to reproduce:

Install the usbnet package, enable a usb0 device in /etc/config/network

(in my case this is a c.h.i.p, but most hackerboards except the pi do usbnet)

config interface ‘usb0’

      option ifname 'usb0'            
      option proto 'static'                 
      option ipaddr '172.26.97.200'
      option netmask '255.255.255.255'
      option ip6assign '64'           
      option ip6class 'local' 

So long as the chip beats the router to booting, this gives it an ipv4 and ipv6 ULA out of the pool.

Reboot the device on the other side. The kernel deregisters and registers the usbnet driver, and netifd assigns the ipv4 address again.

However the ip6 subnet that was assigned from the ula does not come back. Haven’t tried it with a public address.

ifup/ifdown does not work and the ifstatus usb0 does not show any ipv6 addresses assigned.

Overall, it may be the cross compilation process, overlay or something else entirely.

11.02.2017499Base systemBug ReportVery LowLowWiFi client mode leaves router inaccessible if upstream...TrunkUnconfirmed Task Description

This bug was originally reported to the OpenWrt team and there is a discussion of it in their mailing list. Luiz Angelo Daros de Luca suggested reporting here (and switching to LEDE, which I will do).

I have a TP-Link TL-MR3020 v1.9 with Chaos Calmer 15.05.01. I’m using it to provide a WiFi access point to my phone/tablet while I travel, and it’s acting as a WiFi client for the various hostels I visit.

If you configure it as a wifi client with a wwan interface using the LuCI scan/join wizard, and then you configure a wifi access point on the same radio, the router works as expected and when you connect to the router’s AP, you get Internet via the client connection.

However, if you move out of range of the network the router is a client of, or if it goes down, when you power off the OpenWrt router and power back on, the access point won’t come up.

The AP will only come up if the client network you configured is also working; so you have no way to connect to the router over wifi, and no way to reconfigure the router, if that client network is down or out of range.

This is a particular problem for a travel router because it will often move it out of range of the original upstream network, and you may only have a wifi-capable device with which to reconfigure it.

The Ethernet port on the router does remain active, so I can tell it does actually boot. It’s just the radio that doesn’t come up. I managed to get back in range of a network once, and the router worked as expected.

It doesn’t matter whether the AP or client connection are configured first or second on the radio interface, and, unticking “bring up on boot” for the wwan interface has no effect on the behaviour.

Steps to reproduce: Connect the router to a wifi network as a client using the Join wizard. Add a wifi master-mode access point on the same radio interface. Verify you can access the Internet by joining the router’s new master AP. Reboot the router with the original network it was a client of turned off. Notice the router’s AP you configured never comes up.

Expected behaviour: The master access point of the router should always come up, regardless of the availability of the client network.

The OpenWRT team will not fix it, but had some explanation as to why it is happening. IMO, it’s still a very frustrating bug and most users would expect the behaviour I did.

12.02.2017500Base systemBug ReportVery LowLowfirewall3: missing targets with IPv6 NATopenwrt-18.06Unconfirmed Task Description

When the kmod-ipt-nat6 package is installed, running /etc/init.d/firewall reload or /etc/init.d/firewall restart produces warnings that targets are missing:

 * Populating IPv6 nat table

13.02.2017506Base systemBug ReportVery LowMediumBT Home Hub 5: 5g WiFi jumps to channel 36 and stops wo...TrunkUnconfirmed Task Description

Supply the following if possible:
- Device problem occurs on BT Home Hub 5
- Software versions of LEDE release, packages, r3425-f28eef4 and previous versions
- Steps to reproduce

It can be after a few hours, if WiFi 5g radio0 Qualcomm Atheros QCA9880 802.11nac (radio0) is configured to a Band B channel, it jumps to Channel 36 even though there is no apparent interference.
This appears to happen more frequently overnight during long periods of inactivity. Whilst the device is being used it does not happen.

After it does make the jump, if I stop and restart the device (using luci disable/enable) the device stops, but it fails to restart. Attempts to change the channel and re-enable the device also do not help.

It requires a reboot to restore service.

 


14.02.2017514Base systemBug ReportVery LowLowAny files copied to flash gone after reboot17.01.0-rc2 ...TrunkUnconfirmed Task Description

PCEngines Alix with lede-17.01.0-rc2-r3131-42f3c1f-x86-geode-combined-squashfs.img

Boots fine.

Any software installed or files copied to flash disappear after reboot.

However LAN ethernet IP address is (usually)remembered but did get reset on one occasion.
But WiFi config of a USB dongle is always lost.

The board has a Lexar 16GB UDMA7 CF card. This config works fine with OpenWrt CC.

Reflashing, changing the flash card etc makes no difference.

  no stats available

The only statistics available are the ones provided by `ifconfig`, but I’m not sure whether that is accurate — I’m not seeing any drops even under load.

Note that statistics are available on the switch (through `swconfig show`), it’s only the SoC’s interface that’s impacted.

(While I’m at it, the driver is incomplete in other ways — there’s no support for Pause frames or for scatter-gather, although a quick read of the datasheet indicates that it should be possible to implement these features. I’m not sure that’s important, though.)

27.02.2017563Base systemBug ReportVery LowLowcake qdisc high cpu usage on tp-link 841nTrunkUnconfirmed Task Description

So, I had this crazy idea to just make cake the default qdisk after seeing the battlemesh presentation. Now we are seeing high spikes in CPU usage after some time - the peaks appear to be of periodic nature. I only have some nmeter plots (basically vmstat/sar with dots - it’s a busybox applet) - the high load immediatly vanishes after switching the qdiscs back to fq_codel.

I’ve seen this on 2 841n routers one only using ap+ibss mode the other having wan+lan+ap+ibss+tap interfaces with cake running. Both also run a bridge for the AP.

Is the high system cpu usage expacted behavoir? cake qdisc is just using defaults:

This script does the activation:

# cat /etc/hotplug.d/iface/00-cake-qdisc 
#!/bin/sh

case "$ACTION" in
                ifup)
                grep -q '^sch_cake' '/proc/modules' && {
                        command -V tc > /dev/null || return 
                        tc qdisc replace dev "$DEVICE" root cake

01.03.2017580Base systemBug ReportVery LowLowNetgear R7800 does not receive multicast messages on LA...TrunkUnconfirmed Task Description

Netgear R7800 running lede-17.01.

Multicast packets are not received on LAN (wired) interfaces but work fine on WiFi interfaces. I think the problem is at device/driver level.

The problem was first noticed using Avahi, which did not see announcements on LAN interfaces. However it can be easily reproduced with a simple IP Multicast sender/receiver like https://github.com/GrahamCobb/Multicast-Client-Server-Example

To reproduce:

Run the “client” on the R7800 using:

client 232.0.1.1 4545 100

Run the “server” on another system using:

server 232.0.1.1 4545 100 1000

If the server is connected to the client using a WiFi interface, the messages are received. If it using a LAN, they are not.

The messages are received if the LAN interface is set in promiscuous mode (ifconfig ... promisc) or all multicast mode (ifconfig ... allmulti). They stop again immediately if the mode is turned off.

I believe this is the same problem as reported in https://forum.lede-project.org/t/ipv6-works-only-with-wan-in-promiscuous-mode/490/9 – in that thread it is mentioned that the AC2600 (which uses the same driver) has the same problem.

As the problem goes away in promiscuous or all multicast modes, I am guessing that the device is just not sending the multicast packets to the driver. This could be a hardware bug, a bug in the multicast filter setup code in dwmac1000_core.c or the devicetree incorrectly reporting device characteristics such as the number of multicast filter bins.

03.03.2017591OtherFeature RequestVery LowLowInclude branch info in subject from 'lede-commits'AllUnconfirmed Task Description

Please include the branch being committed to as part of the subject. As it currently stands emails are received:

[source] ubox: update to the latest version
[source] bcm53xx: include Broadcom PHY driver in the kernel

However there’s no clue in the subject that the ubox commit is for ‘master’ (and of interest to me) whilst the ‘bcm53xx’ is a commit to ‘17.01’ (and of much less interest to me)

It’s driving me (even more) insane :-)

04.03.2017592PackagesBug ReportVery LowLow6in4 not creating routes when multiples prefixes usedAllUnconfirmed Task Description

If you need to route several (non aggregatable) prefixes thru a 6in4 tunnel, I’ve not found documentation, but it seems that this will make it:

option ip6prefix ‘prefix::/64 prefix::/48’

(example for 2 prefixes)

Then doing ifstatus interface-ipv6, you can see that both prefixes have been considered under ipv6-prefix.

However, under route, only the first one has a default route for that “source-prefix”.

Creating a manual route, it works, so the bug is not creating automatically that route.

09.03.2017611Base systemBug ReportVery LowHighdnsmasq Ignore resolv file option forget at restartAllUnconfirmed Task Description

If you set up dnsmasq to ignore resolv file it will ignore it until reboot is performed. To make ignore it again the option must be uncheck and apply and then check and apply again.

I have /etc/resolv.conf as a symlink to /tmp/resolv.conf, when the router boots up the contents are the dns offered from dhcp over the wan interface. When the ignore resolv option is checked or unchecked the contens are overwrited to search lan and nameserver 127.0.0.1 but it doesn’t seems to affect as if you uncheck ignore resolv the router resolv names, and when you check again the option it can resolv names even the contents still are search lan and nameserver 127.0.0.1.

I haven’t seen yet any other change that can cause the reboot to make dnsmasq follow resolv file when the option is checked until you uncheck-apply and check-apply.

09.03.2017612Base systemBug ReportVery LowHighWAN to LAN leakage on MT7620 devicesTrunkUnconfirmed Task Description

I am currently testing two MT7620 devices - the ZBT WE826 and the Sanlinking D240. During the first seconds of the boot, I see that packets leak between the WAN and LAN ports. Typically, this results in clients receiving a DHCP reply from my upstream router, rendering the clients without connectivity when the switch is properly initialized. I have also tested with the default firmware and do not see this behavior. Also, if I stop the devices in the bootloader, then packets do not leak until I resume boot again.

In order to try to solve this bug, I have tried to port some (at least to me) missing steps from the bootloader switch code and to the mt7620 switch driver in LEDE. This did not have an effect, at least not on the packet leak. A work-around I have found is to update u-boot and remove the input delay, so that the device will boot immediately. However, this is quite cumbersome to install and not very reliable. I suspect my luck with this work-around is more due to the timing of the DHCP clients in Ubuntu and Windows 10.

Does anyone have any idea as to what could be wrong and where to start looking?

Thanks in advance for any help.

14.03.2017631Base systemBug ReportVery LowLowAR8327 switch link state change check not working on TL...TrunkUnconfirmed Task Description

Hello,

On my TP-LINK TL-WR1043ND v3 (ar71xx QCA9558) with today’s LEDE snapshot, the AR8327 switch isn’t sending port change interrupt events to the CPU.

The `ar8xxx_check_link_states` function in `target/linux/generic/files/drivers/net/phy/ar8216.c` is not being called at all, since not only the messages about port link status change aren’t printed to the dmesg, but the ARL table isn’t getting cleaned either. I don’t understand why this is happening...

This regression is not present in other routers with the same AR8327 switch chip (but rev. 2 instead of rev. 4), such as TP-LINK TL-WDR4300 v1 (ar71xx) and TP-LINK TL-WDR4900 v1 (mpc85xx).

(Latest LEDE stable release also does exibit the regression.)

Below you can see a session with LEDE; and a session with OpenWrt CC 15.05.1 release, which does not exibit the problem.

(The CC image is for the TL-WR1043ND v2, since v3 images weren’t built yet at that time; v2 and v3 are the same hardware, as it can be seen from the FCC docs, where TP-LINK requested an ID change from v2 to v3.)

Please let me know if there’s anything I can try to help debug this problem!
