25.09.20181868KernelBug ReportVery LowHighkmod-netem: Unable to handle kernel NULL pointer derefe...TrunkUnconfirmed Task Description

Device is WRT1900ACv2, kernel version is 4.14.71
It is simple to reproduce, just invoke netem such as `tc qdisc add dev eth1 root netem delay 100ms`, it will crash immediately

01.10.20181877KernelBug ReportVery LowHighSD Card corruption on reboot after power failureTrunkUnconfirmed Task Description

- problem occurs on zbt-we1326 with mt7621 cpu with mtk_sd kernel module loaded.
- openwrt latest snapshot(30-08-2017) firmware downloaded from openwrt.
- Steps to reproduce
1. setup extroot on the sdcard with a partition of 1gb(ext4)(boot) mounted as /overlay and 31gb(f2fs)(data) mounted at /media/
2. works fine on normal reboot(through ui).
3. turn off router power and start the router by plugging back in. notice corruption of extroot or data folder or both . it doesn’t happen rarely but it definitely happens on subsequent power off/on cycle.

 


26.12.20182026KernelBug ReportVery LowHighkernel ipq806x Oopsopenwrt-18.06Unconfirmed Task Description

Device: netgear,r7800
Version: 18.06.1

Steps to reproduce:
The crash will happen with 100% certainty, but what exactly causes the problem is a little hard to say. It looks like large internet frames on WAN interface somehow trigger the error.

The WAN interface (eth.2) is untagged, on the LAN ports besides 1 untagged VLAN, 3 untagged VLANs exist. Only (possibly) relevant extra installed package is ip-tiny; it isn’t used though for any custom configuration though.

From the syslog (from boot till Oops, seemingly non-related stuff redacted out):

27.02.20192150KernelBug ReportVery LowHighCrashlogs are empty/borken - TD-W8970 v1AllUnconfirmed Task Description

Device TD-W8970 v1.
Lot of crashes, all does not produce anything on logs (even tried to crank up log levels and saving to USB, to be sure to read last lines logged, but no errors is shown).
After the automatic reboot I can see the message

Crashlog allocated RAM at address 0x3f00000

with logread.
No log file is generated inside

/sys/kernel/debug

.
I compiled a custom image with

/dev/mem

enabled and dumped the memory after 0x3f00000 (basically last MB of ram available) and I can only see the bytes “A1 EE DE AD” followed by ~1KB of “00” and after that probably other programs code.

In this thread there is the full explanation about how this device is currently unstable, and having no logs available makes debugging x10 times harder..

10.03.20192176KernelBug ReportMediumHighubiquiti loco xw (AR9342 Rev.2) stops receiving on wire...AllNew Task Description

This bug has been existing as long as the ubiquiti loco xw 5 ghz hardware is around, probably what we are dealing with is a hardware bug in the AR9342 Rev. 2 chip. It is somehow hard to reproduce, but it hits us reliable every couple of hours, sometimes days, running any version of OpenWrt up to todays master branch. It just happened again and this time I decided to check if the bug is actually listed on FS – in addition to creating the usual cron-job executing `iw dev wlan0 scan` every minute. There is even a watchdog in the community libremesh repository designed to catch exactly this bug:
https://github.com/libremesh/lime-packages/blob/master/packages/cotonete/Makefile#L21

So to run into it, here we got 2 ubiquiti nanobeam m5 devices running OpenWrt ar71xx/generic loco-m-xw pointing at each other over a distance of roughly 2km. This link is acceptable, but not perfect and slightly asymmetric.

Device A (worse RX SNR):

Device B (better RX SNR)

Now it so happens that device A (and always only device A!) becomes deaf after some hours of mostly sending lots of traffic to device B. It will continue to send beacons, but loose all associations. device B will keep trying setting up a link, but it keeps ending up in ‘BLOCKED’ state and dumps using a monitor mode interface show that device A simply doesn’t react at all to any of the frames send by device B. A simple `iw dev wlan0 scan` on device A (which doesn’t give any results) fixes the problem.

The channel seems rather unused otherwise and signal quality only varies by weather conditions. Interestingly this seems to happen on non-DFS channels only. And it happens on Ad-Hoc mode (unencrypted, never tried encrypted) and 802.11s (open ie. setup via `iw` tool as well as with SAE ie. running `wpa_supplicant`) equally. It doesn’t happen on all nodes, but only on those with rather bad signal or at least one far-off neighbor.

Maybe related to FS#1246

I saw this occuring on ubnt nanostation loco m5 XW as well as on all nanobeam m5 variants (which is supposedly compatible with the loco-m-xw image).

01.04.20192216KernelBug ReportMediumHighath79 - eth0 Spasmodic Link Speed After Driver Changes?...openwrt-19.07Assigned Task Description

I’ve built the latest version of OpenWRT with stock packages and configuration, however, after random amounts of time, all clients lose connectivity because the eth0 link speed drops from the regular 100 Mbps Full Duplex to 10 Mbps Half Duplex, only to reconnect again after a couple of minutes (seconds to mintes, it depends), and do it again at another random time.

[18580.106696] eth0: link up (100Mbps/Full duplex)

[24500.880989] eth0: link up (10Mbps/Half duplex)

The logs aren’t very useful, it seems. Both syslog and dmesg show the same.

I suspect this started happening after this series of commits (ending with this one) where there were driver changes to the switch, as it didn’t happen before I recompiled a new build with all those newer changes:

The problem has been confirmed on gl-inet b1300 and Asus AC58u, latest snapshot and 18.06.2.

very low ipsec throughput under normal strongswan road-warrior configuration, but performance become reasonable after installing strongswan-mod-kernel-libipsec, it means bypass kernel’s ipsec stack.

For instance

# CONFIG_NFT_RT is not set

is the likely cause for

please enable the kernel conf in order nft can utilize its full potential, particularly since being dedicated to routers.

16.07.20192391KernelBug ReportVery LowHighmac80211: ath9k AP fails to honour client's power save ...TrunkUnconfirmed Task Description

Context:

I am using one device in AP mode, the other in client mode.
The client uses wpa_supplicant to do background scan to other channels that the data channel.
I am running iperf (UDP) from the AP to the client.

My device is home-made, Cavium development board-based, equipped with Compex WLE350NX.
It works correctly with kernel 3.18 and the 2015 wireless backport.
I updated to kernel 4.9 and the wireless backport 4.19.32-1, the last one from the trunk. (previously I used backport-2017-11-01 with the same result).

I am running wireshark with Airpcap to spy the wireless link.

Problem:

* When the client scans offchannel, it correctly sends nullfunc frames around the offchannel period, with the PM bit set then unset.

* However, during this time, the AP continues to send data to the client.

 

* This results in a lot of lost frames, though I set the powersave buffers to high values on the AP side.

After some research I saw that the same kind of problem was fixed several times(*), but since there where so many changes in the queue management, I cannot really compare his work and the current state of the driver.

Any idea / patch / research directions ?

Software Configuration
- kernel compiled with CONFIG_VIA_RHINE_MMIO set to “Y”

Hardware Configuration
- two MiniPCI OX16PCI954 Quad UART installed
- one module installed on the router’s miniPCI slot
- one module installed on the daughter board’s miniPCI slot
- /dev/ttyS5 continuously bombarded by messages over the serial
- Eth0, Eth1, Eth1 are bridged
- Eth1 (via-rhine) is continuously bombarded by TFTP requests
- Eth0 executes minicom monitoring /dev/ttyS5

Tasks
minicom
in.tftpd

The machine looks working properly in the window time of some hours, but within 48 hours some weird things happened, and it crashed due to what seems memory corruption in kernel space.

Workaround

18.11.20192614KernelBug ReportVery LowHighath10k 5 GHz connectivity issues for some client device...openwrt-19.07Researching Task Description

* - Device problem occurs on TP-Link Archer C2600.

* - Software version of OpenWrt 19.07-rc1 and older 19.07.

* - From the first version, which I tested after the release of 19.07, I have a problem with 5GHz radio / Wi-Fi. On two devices: LG OLED B8 55 “OTT and Cyfrowy Polsat STB OTT does not work internet. Both devices connect to the network, but do not have access to the Internet. In the connection diagnostics on the TV, the message pops up that it is a DNS error. On 2.4 GHz Wi-Fi everything is fine.

* - I have reverted to the 18.06 to fix the problem for now.


12.12.20192670KernelBug ReportVery LowHigh[ATH79] unstable USB on WR1043 v2openwrt-19.07Unconfirmed Task Description

Hi there!

I recently upgraded my TP-Link TL-WR1043 v2 device to the ath79 targeted 19.07-rc2 release using my custom build, which I have compiled with the image builder.

make image PROFILE=tplink_tl-wr1043nd-v2 PACKAGES="block-mount curl diffutils ethtool iperf3 iwinfo htop kmod-fs-ext4 kmod-usb-storage luci mailsend-nossl minidlna nfs-kernel-server ppp-mod-pppoe shadow-su transmission-daemon-mbedtls transmission-web vsftpd zram-swap -ip6tables -kmod-ip6tables -kmod-ipv6 -kmod-nf-conntrack6 -kmod-nf-ipt6 -libopenssl1.1 -odhcp6c -odhcpd-ipv6only -luci-proto-ipv6 -libip6tc2"

I just recently rolled back to an EXT4 partition, because of it's smaller memory footprint. (just mounting a ~50GB f2fs partition consumes around 10MBs of memory)
So in the very first attempt I wanted to copy back everything to my Transcend 790K. But after the first 500-1000 MBs(mix of archives, image, text and video files), the transaction speed has fallen down couple of times. I thought maybe the passive FTP connection was the problem, because after a few automatic reconnect attempts, the speed of the copy has been normalized again and in the end the device was connected. Later I found that the USB devices was reseted.
I had another try with a Sandisk Ultra Fit drive (SDCZ-43), but the result and the configuration was pretty sam. ~50GB EXT4 partition without journal and without barrier.
I force upgraded the machine to the ar71xx target and Filezilla so far copied back 16GBs without any problem.
Target ATH79 seem to be has so many problems with the USB subsystem, please see my other bugreport for the WDR4300 as well: FS#2567 - [ATH79] USB speed degradation on WDR4300.

Let me know if I can help the bughunting any way,
thanks and regards!

28.12.20192707KernelBug ReportVery LowHighmt7621/ath9k: unreliable AP with hardware encryptionTrunkUnconfirmed Task Description

Board: MikroTik Routerboard RBM33G (ramips/mt7621)
Interface: MikroTik R11e-2HPnD (ath9k/ar9582)
Tested versions: 18.06.5, snapshot

Some background: I’ve been using RB433AH & UBNT XR2 (ath5k) as home AP for many years. It was extremely reliable with OpenWRT, LEDE and OpenWRT once again. However, the 802.11g is not sufficient nowadays, so I decided to upgrade. I’ve acquired a RBM33G board and R11e-2HPnD module, but this setup is very unreliable for me.

The bug: At some point, the AP cannot receive (decrypt?) packets from a station, but the connection is still established.

Details:

  • It can happen on any active station connected to AP, but only one stalls at a given time (not all of them).
  • AP actually receives data from STA, as the RX byte counter increases, but the RX packet count is typically stuck at the same value. For example, several subsequent calls to `iw wlan0 station dump` show: rx bytes: 12121338 / 12127266 / 12141740, rx packets: 1282 / 1282 / 1282.
  • Driver discards the packets, as the replay counter greatly increases when this bug occurs. (e.g. /sys/kernel/debug/ieee80211/phy0/keys/3/replays: 484947)
  • There is nothing relevant in `dmesg` or `logread`.

Reproducibility:

  • It happens after several hours of a typical traffic.
  • I can trigger it manually much faster by passing high data throughput between clients (e.g. using iperf).

Configuration:

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '11'
        option hwmode '11g'
        option path 'pci0000:00/0000:00:00.0/0000:01:00.0'
        option htmode 'NOHT'
        option txpower '16'
        option disabled '0'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid '<SSID>'
        option encryption 'psk2+ccmp'
        option key '<KEY>'

Stations tested:

  • Dell Latitude E7440 with Intel Wireless 7260 (iwlwifi), running linux 5.4.6
  • Dell Latitude E7270 with Intel Wireless 8260 (iwlwifi), running linux 4.19.91
  • RB411U with DBII F20-PRO (ath5k, AR5414), running LEDE 17.01.4 (in WDS link)


What does NOT help:

  • Changing the basic configuration (SSID, key).
  • Disabling 802.11n.
  • Disabling WDS (both AP & STA).
  • Disabling SMP (nosmp kernel cmdline option).
  • Using another version of hostapd, i.e. wpad-mesh.
  • Changing miniPCIe slot on the RBM33G board.
  • Disabling CPU powersave in MikroTik bootloader.

Workarounds:

  • Disable the encryption at all, but that’s obviously not an option.
  • Disable hardware encryption with ath9k’s nohwcrypt=1 parameter.

This bug does not occur with software encryption, at least in 802.11g mode. In 802.11n mode, the throughput is limited to a little over 30 Mbps and there are frequent disconnects. Apparently, the CPU is not the limiting factor, as `top` reports usage of approximately 10%.

Unfortunately, this bug renders the AP unusable for me, because I need the best reliability.

I also tested this setup with different board and (so far) I cannot reproduce this bug on RW2458N (ar71xx) & R11e-2HPnD with OpenWRT 18.06.5.

12.01.20202730KernelBug ReportVery LowHighTL-WR841N v8 ath79 Link Unstableopenwrt-19.07New Task Description

Probably related to https://bugs.openwrt.org/index.php?do=details&task_id=2216 which was reported almost a year ago. The bug is still not fixed though.

Are there any plans to fix it or will 18.06 be the last stable version for this and probably other devices?

There are old closed reports about it 2353 2354

I have tried with kernel 4.14 and with kernel 4.19 from the 19 branch and also removing the nf_conntrack_rtcache module, but the result is the same.

There are times that I see no BUG at all, others where I see it appear between 1 and several times. I use several docker containers and depending on the races, sometimes everything launches well and afterwards (if I don’t play with new docker instances) it is 100% stable whereas other times I have to reboot up to 3 or even 5 times for everything to work reliably.

22.02.20202849KernelBug ReportVery LowHighAR8327 can't work on hybid VLAN tagging mode.AllUnconfirmed Task Description

I have 2 vlan channel in family network for IPTV STB with VLAN 51 & 85. My router is WZR-HP-G302H which have the same hardware with WZR-HP-G300NH2.

With the default vlans1&2, I set the switch has 4 vlan channels:
vlan1 goes cpu(port0) tagged, lan(port1-4) untagged, wan(port5) off,
vlan2 goes cpu(port0) tagged, lan(port1-4) off, wan(port5) untagged,
vlan51(for multicast) goes cpu(port0) untagged, IPTV(port1) tagged, PC(port2-4) off, wan(port5) tagged,
vlan85(IPTV stream) goes cpu(port0) untagged, IPTV(port1) tagged, PC(port2-4) off, wan(port5) tagged.
And I use TTL to logon my IPTV STB, with ifconfig eth0&eht0.85, I can see the STB got both internet routing ip(192.168.2.x) & IPTV intranet ip(217.xxx.xxx.xxx), but when I’m trying to ping 192.168.2.1, it failed.
When I set wan(port5) with vlan51&85 off, the internet was back, and got acks from ping 192.168.1.1.
So I tried to replace wan to port1-4 ,IPTV port to port2-5 with all the possibility, it shows the same problem.

Then I try to use the route with AP mode:
vlan1 goes cpu(port0) tagged, lan(port1-5) untagged,
vlan51 goes cpu(port0) off, lan(port1-5) tagged,
vlan85 goes cpu(port0) off, lan(port1-5) tagged.
The STB still got 2 IPs , which 192.168.1.x & 217.xxx.xxx.xxx both offerd by Modem’s DHCP.
And the same problem appears: only port with both vlan51&85 turned off can got internet access, others not.

I tried firmwares openwrt-19.07.1-ath79-generic-buffalo_wzr-hp-g302h-a1a0-squashfs-sysupgrade.bin, openwrt-19.07.1-ar71xx-generic-wzr-hp-g300nh2-squashfs-sysupgrade.bin and openwrt-18.06.7-ar71xx-generic-wzr-hp-g300nh2-squashfs-sysupgrade, they shows the same problem while the port sets in hybird mode with vlan tagged & untagged.

So I have to seeks documents and troubleshoots for help. Finally I found the ticket:(https://dev.archive.openwrt.org/ticket/12181.html) told the same problem.
But the ticket is 5 yeas ago, and the ar8216.c no in 19.07.1 and 18.06.7 is definitely different, the “k”‘s path is no longer available with new ar8216.c, so I have to report the bug here again.
Is there any patch or a new fixed version of ar8216.c work with hybird mode which inculde tagged & untagged frame on the same port? Thank you very much.

14.04.20203008KernelBug ReportVery LowHighGenesys Logic USB 3.0 hub not recognized by the systemAllUnconfirmed Task Description

Hi) I have a problem with Genesys Logic USB 3.0 hub (based on GL3523) on my Xiaomi MiR3G. The system don’t see this hub. Same on 4.14 & 4.19 kernel. Bought on AliExpress

Workaround: insert a half of the plug into router port → the system recognize USB 2.0 hub, then insert the plug to the end → the system recognize USB 2.0 & USB 3.0 hubs as it must be.
1. Normal connect hub → the log is empty.
2. Insert a half of the plug:

But after reboot the same: no hub at all.
Nope, the connector is normal, recognized correctly on PC & smartphone. So, this is kernel or driver bug.

26.04.20203049KernelBug ReportVery LowHighsunxi / lamobo-r1: switch not working with kernel 5.4TrunkUnconfirmed Task Description

- Device problem occurs on

Lamobo-R1 BananaPI Router

- Software versions of OpenWrt/LEDE release, packages, etc.

OpenWRT Snapshots (Imagebuilder) sometime after r12688-46d0ce19f1

- Steps to reproduce

Write any recent image to SD card, it boots but networking does not work.


Hello,

I’m doing regular updates with imagebuilder (about once per week) for Lamobo-R1. Some time after r12688-46d0ce19f1 the networking configuration broke.
I’m assuming the cause is kernel 5.4, because my last working image is from 2020-03-22 and it stopped working the week after, around 2020-03-29.

As far as I can tell the problem lies in the switch configuration: The switch is not found, the bootlog of kernel 5.4 contains no reference to “b53”.

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.

11.05.20203091KernelBug ReportVery LowHighLatest build does not work properly on Banana Pi R2TrunkUnconfirmed Task Description

I compile my image according to the given guide: https://openwrt.org/toh/sinovoip/sinovoip_banana_pi_r2

With kernel version 4.19 everything went smooth (OpenWrt Snapshot shown after boot was r12726-92616c4227).

Then i wanted to upgrade to the current master and after applying the new bpi_bananapi-r2-kernel.bin and root.squashfs files the boot process stops every time at the same point (see attached file boot.txt).

I did the follwing steps:

  1. ./scripts/feeds update -a
  2. ./scripts/feeds install -a
  3. make -j8 menuconfig
  4. follow instructions for menuconfig on guide
  5. make -j8 kernel_menuconfig
  6. follow instructions for kernel_menuconfig on guide
  7. I did not apply the patch that was given. I didn’t encounter any problems with failing network connections even with the old linux kernel. It also does not make any difference according to the current problem.
  8. make -j8
  9. changed repositories.conf according to the guide
  10. make image PROFILE=bpi_bananapi-r2
  11. apply new kernel-file and rootfs according to the guide

I tried this several times with different configurations but the result was the same anyway.

It seems like there is a bug at loading rootfs from MTD.

 


30.05.20203138KernelBug ReportVery LowHighmac802.11sh commit broken and causing one radio to dropAllUnconfirmed Task Description

Source of the problem: commit `b551660` `/lib/netifd/wireless/mac802.11sh`
Device problem occurs on: Netgear R7800, LinksysWRT1900ACSv2, Netgear EX6400, TP-Link Archer C60
Software versions of OpenWrt/LEDE: v19.07.3 and master

Steps to reproduce: I created a post here https://forum.openwrt.org/t/wrt1900acsv2-only-one-wifi-radio-is-staying-up/64273 regarding the last WiFi client disconnecting from the AP stops working on that radio.

If I go into ‘Network > Wireless’ in LuCI and click the ‘Restart’ button on the 2.4 or 5GHz radio, that radio is the only radio that stays working, whereas the other radio says disabled and wireless not associated.

I can also replicate this via SSH/CLI running `wifi up radio0` disables radio1. Running `wifi up` brings radio1 up this but drops radio0. If I run `wifi up` a second time both radios come back up.

My forum has been linked to a Netgear 7800 thread found here https://forum.openwrt.org/t/netgear-r7800-exploration-ipq8065-qca9984/285/2259 and there has been confirmation that there appears to be a problem with commit `b551660` from May 4, 2020 for `openwrt/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh`. Rolling back to commit `0495324` appears to fix this issue.

I too can confirm this by renaming `mac80211.sh` to `mac80211.sh.old`, downloading commit `0495324`, placing it under `/lib/netifd/wireless`, setting the permissions to `0755` and then running `wifi up radio0` in SSH/CLI. Radio0 (5GHz) drops as expected and after a couple of seconds it is back up all without affecting the radio1 (2.4GHz).

This is the broken commit https://github.com/openwrt/openwrt/commit/b5516603dd90215d5cdc5bac7ea496a6c758bb0f

kernel 4.14 (OpenWrt stable 19.07.x) seems to fall through the cracks somehow. With kernel 5.4 in upcoming stable OpenWrt 20.x still far out it would make sense to backport the patch into OpenWrt stable 19.07.x

12.07.20203226KernelBug ReportHighHighGL-AR300M: Frequent WAN (eth1) link down / link upopenwrt-19.07Assigned Task Description

Trying to find a solution for the issue with Wi-Fi on the latest stable release (19.07.3) installed a snapshot version if OpenWrt. I’m not sure if Wi-Fi issue is solved (difficult to test in the current situation) but there is another problem now which was not happening on the stable branch: WAN link (eth1) goes up and down all the time.

Details:
- Device: GL-AR300M
- OpenWrt Version: OpenWrt SNAPSHOT r13770-edbc8e5512 / LuCI Master git-20.190.40190-44b0fcb
- Kernel: Linux OpenWrt 5.4.50 #0 Fri Jul 10 09:39:05 2020 mips GNU/Linux
- OpenWrt snapshot downloaded from https://downloads.openwrt.org/snapshots/targets/ath79/nand/openwrt-ath79-nand-glinet_gl-ar300m-nor-squashfs-sysupgrade.bin

Configuration:
- WAN6: eth1, DHCPv6
- WAN: ds-lite (IPv4 over IPv6)
- LAN: eth0 + wlan0

How to reproduce:
1. Flash firmware
2. Install ds-lite and luci and reboot
3. Configure WAN as DS-LITE
4. Configure Wi-Fi
5. Connect to Wi-Fi and start using internet

Result: internet access disappears for short time frequently at random times

23.07.20203244KernelBug ReportVery LowHighath9k_htc: Kernel oops in snapshot on RaspberryPi 4 (at...TrunkUnconfirmed Task Description

- Device: Raspberry Pi4
- Snapshot kernel 5.4 with 5.7 backport
- Install ath9k_htc dongle and connect WiFi client

So, I have been able to tackle down who is causing a kernel panic and reboot of my RPi4 with current snapshots.

It is the ath9k_htc dongle I use but only if there are clients connected to it
Apparently it corrupts memory so the kernel panic look quite different among them, here two caputer with serial:

I have tried two different RPi4 hardware and two different SD cards. No other devices are connected to the USB ports,ath9k_htc dongle is connected to USB 2.0 port.

With 19.07.x on a Orangepi PC2 device, the same dongle behaved correctly

15.08.20203285KernelBug ReportVery LowHighCan't change MTU on IPQ806x devicesTrunkUnconfirmed Task Description

- I’ve personally tested it on ZyXEL NBG6817
- Any version with https://patchwork.kernel.org/patch/11283121/ patch applied
- To reproduce:
# ifdown wan
# ifconfig (wan_interface) MTU 1499 (or 1501 or anything other than 1500)

This bug is caused by txfifosz being 0 on IPQ806x devices (and possibly more) unless tx-fifo-depth is specified in device tree, potential fix would be to specify tx-fifo-depth in device tree for all affected devices, or, check if txfifosz == 0 and then allow MTU change.

19.09.20203350KernelBug ReportVery LowHighKernel Warning in module mac80211/tx.copenwrt-19.07Unconfirmed Task Description

Hi,

I am using the following with the latest update of openwrt:

Model Netgear R6220
Architecture MediaTek MT7621 ver:1 eco:3
Firmware Version OpenWrt 19.07.4 r11208-ce6496d796 / LuCI openwrt-19.07 branch git-20.260.30581-915a64c
Kernel Version 4.14.195

The problem occured already with 19.07.3 several times, so I upgraded to 19.07.4, but the problem remains.
The wifi module kept crashing and in consequence a part of the wifi devices cannot connect anymore. Sometimes the router
recovers by itself, sometimes not and a reboot is necessary to get wifi working again. It mostly affects the 2,4 GHz band
and not the 5 GHz band, but that might be related which device is renewing DHCP or which ones are not (I am not sure).
A reboot solves the problem, but after some time, the problem occurs again. After the below warning, the router runs without
further problems for 2 days now. So it seems pretty rare. Nevertheless, the same hardware was working fine with 18.x
openwrt for a year at least. No kernel warning at the time. I cannot completely rule out that the HW is broken as it is
of age, as you can see. Any hint on what I should report or test myself is welcome! I can help debug and even install
updates that should fix the problem, if necessary. The router ist just used as an access point - routing is taking
place elsewhere.

Here is the korresponding kernel warning, where I included the immediate log entries before and after:

[1] assumes that u-boot image is smaller than 512 KB, but this is no longer the case. Followed the instructions without a second thought and bricked my device. It could have used ${filesize} like the sections below it, or simply use 640 KiB instead of 512 KiB. (The 660 KiB in the section might be a typo, it is not multiple of 128 KiB)

Besides, links in [2] are mostly broken and outdated. In addition, for V4 A3 devices, there are no test pads for JTAG.

27.10.2016253Base systemBug ReportVery LowHighMulticast over wireless ceases to work properly after a...AllNew Task Description

I am having a problem on a UBNT UAP-LR where, if many clients stay connected the router for a long time, multicast packets will stop being reliably sent to the wireless clients. I can reproduce this with LEDE r1953, but it goes back at least as far as OpenWRT 15.05.1 with kernel 3.18. I can not, however, reproduce it on another network with the same WAP but with only one or two wireless clients.

This originally manifested as IPv6 ceasing to work since the (multicasted) RA packets were not reaching the wireless clients. I used tcpdump on the WAP and determined that the RAs were arriving through the wired interface and leaving through the wireless interface as they should, but tcpdump on the client indicates that a vast majority of the RAs are never received. (Please note that the IPv6 issue is not reproducible with the router running OpenWRT/LEDE and odhcpd, since odhcpd unicasts RAs sent as a response to an RS instead of multicasting them, while it is reproducible when the router is running radvd, for example as pfSense does.)

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:

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.

 


17.04.2017714Base systemBug ReportVery LowHighARP/Broadcast does not reach other clients in the same ...AllUnconfirmed Task Description

I have the default bridge with ethernet and WLAN in it. When i try to send data from a client to another, both connected to the same WLAN SSID, it doesn’t work (Destination unreachable).
Wireshark shows that it sends endless ARP requests to Broadcast, but the other clients in that WLAN never get it (and therefore can’t answer). The broadcast gets still delivery to every client connected through Ethernet. If i create a second WLAN SSID (even on the same adapter) and and add it to the bridge, it gets also all broadcast packets from the other WLAN...
So if i put the 2 clients in different WLAN SSIDs or ethernet they get the broadcast from each other, but not when both are connected to the same.

The isolate option is not set in the wireless config.

19.04.2017717Base systemBug ReportVery LowHighWRT3200ACM USB 3.0 ProblemAllUnconfirmed Task Description

I can´t get my Seagate Expansion Portable 1TB STEA1000400 USB3.0 drive to be be recognized on the USB 3.0 port of the router after a reboot or cold start on WRT3200 but if i remove and hotplug the drive, it is automatically detected and can be mounted.
It happens with images from Openwrt 15.05.1, LEDE 17.01.1 and many snapshots from both projects that i have installed. I have no problem with another usb2.0 drive from Samsung that is installed in another USB2.0 port.
