11.01.20213571KernelBug ReportVery LowCriticalKernel Drops Packets and causes heavy re-transmissionopenwrt-19.07Unconfirmed Task Description

Supply the following if possible:
- Device problem occurs on - Netgear R6220
- Software versions of OpenWrt/LEDE release, packages, etc - OpenWrt 19.07.04 & 19.07.05, mt7621
- Steps to reproduce - No Specific steps to reproduce the problem. Problem automatically starts occurring after a few weeks of usage. Upon running tcpdump on the bridged lan interface where majority of my clients are connected, many packets were dropped by the Kernel which caused many re-transmissions.

root@OpenWrt:~# tcpdump -i br-lan -w /mnt/sda1/tcpdump/tcpdump.pcap
tcpdump: listening on br-lan, link-type EN10MB (Ethernet), capture size 262144 bytes

39397 packets received by filter
14785 packets dropped by kernel
root@OpenWrt:~#

During the tcpdump packet capture, all I tried doing was browse various web pages from one client and do a speedtest from another client. The web pages would either never load and load after several re-attempts. Speedtest would fail to complete and error out.

Hi all
With snapshot r5117-fbde9ac, at least on a bananapi (cortex-a7) the USB ports are down, apparently there is some problem with VBUS (maybe DT problem?)
Here the dmesg after boot

04.08.20181728KernelBug ReportVery LowHighNewifi D1- Unable to rebootAllUnconfirmed Task Description

Newifi D1, openwrt trunk, 18.06, etc.

This device can not reboot and there is a patch that can fix this problem.
The official builds don’t include it, so the only way to solve it is to build the firmware by ourselves, which is very inconvenient.

I hope there is someone who can solve this problem.

Thank you!

The patch is from https://forum.openwrt.org/t/newifi-d1-unable-to-reboot/7910/8

30.08.20181826KernelBug ReportVery LowHighFQ_codel is the wrong qdisc for the CAN busTrunkUnconfirmed Task Description

Supply the following if possible:
- Device problem occurs on
CAN bus
- Software versions of OpenWrt/LEDE release, packages, etc.
all
- Steps to reproduce

 bring up a can device that expects pfifo-fast, rather than noqueue

We finally had an edge case where fq_codel is totally the wrong thing.

https://marc.info/?l=linux-can&m=152785826628439&w=2

https://github.com/systemd/systemd/issues/9194

I don’t know how many can bus devices expect pfifo_fast, rather than noqueue. So far as I can tell the flow dissector doesn’t engage, so no FQ, but can is oft blocking bus so codel can drop more often than pfifo_fast does.

- 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.

 


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).

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.

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 ?

05.11.20192578KernelBug ReportVery LowHighrb532 via-rhine kernel crash when compiled with CONFIG_...TrunkUnconfirmed Task Description

- Device problem occurs on

rb532A, with two miniPCI Oxford Semiconductor Ltd OX16PCI954 modules installed

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

kernel 4.4.197

- Steps to reproduce

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!

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.

Looking through the sources, I see the module being copied, but I don’t see the requisite kernel configuration to force it to be built:

philipp@ubuntu16:~/lede2$ fgrep -i -r nft_reject_ipv4 Makefile rules.mk Config.in config include package target
include/netfilter.mk:$(eval $(if $(NF_KMOD),$(call nf_add,NFT_CORE,CONFIG_NFT_REJECT, $(P_XT)nft_reject $(P_V4)nft_reject_ipv4 $(P_V6)nft_reject_ipv6),))
philipp@ubuntu16:~/lede2$

I do see config state for nft_reject.ko however:

philipp@ubuntu16:~/lede2$ grep -i -r ‘nft_reject’ Makefile rules.mk Config.in config include package target
include/netfilter.mk:$(eval $(if $(NF_KMOD),$(call nf_add,NFT_CORE,CONFIG_NFT_REJECT, $(P_XT)nft_reject $(P_V4)nft_reject_ipv4 $(P_V6)nft_reject_ipv6),))
include/netfilter.mk:$(eval $(if $(NF_KMOD),$(call nf_add,NFT_CORE,CONFIG_NFT_REJECT_INET, $(P_XT)nft_reject_inet),))
include/netfilter.mk:$(eval $(if $(NF_KMOD),$(call nf_add,NFT_BRIDGE,CONFIG_NFT_BRIDGE_REJECT, $(P_EBT)nft_reject_bridge),))
philipp@ubuntu16:~/lede2$

and the synthesized .config in the kernel directory and the built modules are:

When I build, I get prompted for the following kernel symbols:

Verify kernel signature during kexec_file_load() syscall (KEXEC_SIG) [N/y/?] (NEW)

Netfilter nf_tables support (NF_TABLES) [M/n/y/?] m
Netfilter nf_tables set infrastructure (NF_TABLES_SET) [M/n/?] m
Netfilter nf_tables mixed IPv4/IPv6 tables support (NF_TABLES_INET) [N/y/?] (NEW)

IPv4 nf_tables support (NF_TABLES_IPV4) [N/y/?] (NEW)

IPv6 nf_tables support (NF_TABLES_IPV6) [N/y/?] (NEW)

Detect Hung Tasks (DETECT_HUNG_TASK) [Y/n/?] y
Default timeout for hung task detection (in seconds) (DEFAULT_HUNG_TASK_TIMEOUT) [120] (NEW)
Panic (Reboot) On Hung Tasks (BOOTPARAM_HUNG_TASK_PANIC) [N/y/?] (NEW)

which makes me wonder if part of the default kernel config is incorrect... including symbols like CONFIG_NFT_REJECT_IPV4, 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

This is the working commit https://github.com/openwrt/openwrt/commit/0e522d5f4a31182312bd115c26c7edb654769724

Supply the following if possible:
- Device problem occurs on
- Software versions of OpenWrt/LEDE release, packages, etc.
- Steps to reproduce

 

X86_64 arch, kernel fails to insert XFRM states with AES-GCM as transform.
Testable with
ip x s add proto esp dst 14.0.0.70 src 14.0.0.52 spi 0×07 mode transport reqid 0×07 replay-window 32 aead ‘rfc4106(gcm(aes))’ 0x44434241343332312423222114131211f4f3f2f1 128 sel src 14.0.0.52/24 dst 14.0.0.70/24 proto tcp

Works on Arch.
Result on X86_64 OpenWRT 19.07.3:
RTNETLINK answers: No such file or directory

On Arch 5.6.15-arch1-1, works (no output, ip x s shows the state).
Also fails 100% of the time when tested using an IKE keying daemon, e.g. strongSwan

This happened on OpenWrt SNAPSHOT r13520-68b94f0fb4, but it’s pretty random. I haven’t been able to figure out what causes it. It usually happens at least once within a week. I’m not sure why there’s no call stack here, I also tried `cat /sys/kernel/debug/crashlog` a few hours after it happened and got a “No such file or directory”.

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:

14.10.20203386KernelBug ReportVery LowHighRegression: Broadcom Roboswitch B53TrunkUnconfirmed Task Description

Hi,

in the current trunk version, Broadcom Roboswitch will not work for certain router models. However, in the past it did work.

Building OpenWrt from scratch results in a working switch with v17.01.5 (from 15 Jul 2018 21:25:16) for target profile “Broadcom SOC, BCM43xx Wifi (brcmsmac)”. Building OpenWrt from scratch for v18.06.0 (from 30 Jul 2018 18:44:34) results in the switch not working for the same target. So the problematic commit must have been between 15 Jul 2018 and 30 Jul 2018, and the problem is still present today.


For v17.01.5

# dmesg | grep switch
[    3.596260] bgmac_bcma bcma0:2: Support for Roboswitch not implemented
[    3.683106] b53_common: found switch: BCM5325, rev 4

Despite the message “Roboswitch not implemented” the switch comes up automatically and I can ping other computers connected through the switch.

# swconfig dev switch0 show

VLAN 1:
        ports: 1 2 3 4 5t
VLAN 2:
        ports: 0 5t

For v18.06.0

# dmesg | grep switch
[    4.174603] bgmac_bcma bcma0:2: Support for Roboswitch not implemented
[    4.275337] b53_common: unsupported switch detected (BCM5304/BCM4)
[    4.281640] Broadcom B53 (2) bcma_mdio-0-0:1e: failed to register switch: -22

The switch does not come up and thus I cannot ping.


I tested this for the (unsuported) router Huawei B593u-12. You can find details about the router, logs, etc. under https://openwrt.org/toh/huawei/b593u-12

This also seems to address other routers, e.g. ZTE H218N, see https://forum.openwrt.org/t/b53-failed-to-detect-switch-on-bcm5358/20011

Hello all,

For some time I see that a problem persists when you want to change the ip address to access the router, this cannot be done from the luci web interface.
The following errors occurred after I connected to the web interface and I wanted to access 5ghz wifi from the phone it can no longer connect to wifi.

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:

12.02.2017503KernelBuild FailureVery LowMediumBuild fails with CONFIG_KERNEL_GIT_CLONE_URI beig setAllAssigned Task Description

When specifying

CONFIG_KERNEL_GIT_CLONE_URI

a clean build fails, as the system assumes a already downloaded/cloned/packed linux-source is present in dl/ which on a freshly checked out openwrt/lede source isn’t the case yet, when

toolchain/kernel-headers

is about to be built.

The build error looks like:

make[3]: Entering directory `/build/lede.git/toolchain/kernel-headers'
zcat /build/lede.git/dl/linux-4.4.42.tar.gz | tar -C /build/lede.git/build_dir/toolchain-arm_cortex-a9+neon_gcc-6.3.0_glibc-2.24_eabi -xf -
gzip: /build/lede.git/dl/linux-4.4.42.tar.gz: No such file or directory
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

The issue apparently is located in

include/kernel-defaults.mk

, line 53ff::

  ifeq ($(strip $(CONFIG_KERNEL_GIT_CLONE_URI)),"")
    define Kernel/Prepare/Default
        zcat $(DL_DIR)/$(LINUX_SOURCE) | $(TAR) -C $(KERNEL_BUILD_DIR) $(TAR_OPTIONS)
        $(Kernel/Patch)
        $(if $(QUILT),touch $(LINUX_DIR)/.quilt_used)
    endef
  else
    define Kernel/Prepare/Default
        zcat $(DL_DIR)/$(LINUX_SOURCE) | $(TAR) -C $(KERNEL_BUILD_DIR) $(TAR_OPTIONS)
    endef
  endif

For the package

kernel-headers

it just tries to access the not-yet downloaded/cloned/packed linux kernel source archive.

14.06.2017845KernelBug ReportVery LowMediumMT7628 : wrong data reading the I2C busAllUnconfirmed Task Description

Hi,

I’ve already talked to blogic about this issue. He asked me to perform some tests on the platform even back to openwrt CC.

The bug in question occurs with the MT7628 chip and the I2C bus (WRTNode 2p board).
Configuring the pinmux and enabling the driver, the kernel correctly sees the i2c bus. But then going to use the “i2cdetect” command from i2c-tools package has a surprising result: devices are actually sees devices that are not connected.

Curious about the problem I connected my DSO and I did the probe of the SDA and SCL pins. Data and clock seem to be transferred correctly. So the problem seems to be in the “reading”.

According to the i2c specification if SDA is pull-low and you do an i2cdetect the system should identify in the bus an ACK for each slave address, this does does not happen and the same list appear again.

Turning back to different versions this still happens, unfortunately I have not been able to test every single commit.
The test I’ve made:

  • Openwrt CC the device was not supported.
  • Openwrt first commit of the device support: the i2c bus was not recognized by the driver.
  • Openwrt trunk, the i2c bus is not registered
  • LEDE 12.01 the problem as described above.
  • LEDE HEAD: the problem as described above.
  • LEDE HEAD 4.9 (kernel): The problem as described above.

i2cdetect result (same result with SDA pulled low) .config wrtnode2p.dts

16.07.2017910KernelBug ReportVery LowMediumRaspberry Pi 3 keeps attempting to change CPU frequency...TrunkUnconfirmed Task Description

I recently updated a Raspberry Pi 3 to a recent LEDE git master build: Reboot (SNAPSHOT, r4576-9fe9175)

The kernel keeps logging the following errors:

[  103.041158] bcm2835-cpufreq:bcm2835_cpufreq_set_clock:84: Failed to set clock: 600000 (-12)

[  103.767870] cpufreq: __target_index: Failed to change cpu frequency: -22

I am seeing ~10ms latency spikes for traffic through the device and I believe these errors are the reason. If I force the scheduler to only run the CPU at its maximum speed with the command below then then errors cease and the latency spikes disappear:

# echo 1200000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq

I looked into the kernel sources and the messages above appear to be saying that there was an error when asking the Pi firmware to change the CPU speed.

I know there is a HW quirk in the RPi3 which means the UART is effected by the CPU speed. I wonder whether this has anything to do with the firmware rejecting the speed change:

25.10.20171113KernelBug ReportVery LowMediumUnknown symbol zlib_inflateAllUnconfirmed Task Description

I’ve experienced a strange issue with zlib_inflate on x84_64 system.
There is no zlib_inflate-related symbols at /proc/kallsyms and modules like btrfs couldn’t be loaded.

17.01 branch and the current master branch, both are affected.

Steps to reproduce:
1. Use attached config file (zlib_inflate-test-config). It’s almost default but I’ve set CONFIG_PACKAGE_kmod-fs-btrfs=y and some other options.
2. Compile LEDE:

make defconfig && make -j $(nproc)

3. Run qemu:

qemu-system-x86_64 -curses -kernel bin/targets/x86/64/lede-x86-64-ramfs.bzImage

4. Try to load btrfs module:

root@LEDE:/# modprobe btrfs
[   23.345891] btrfs: Unknown symbol zlib_inflateInit2 (err 0)
[   23.347096] btrfs: Unknown symbol zlib_inflate (err 0)
[   23.347673] btrfs: Unknown symbol zlib_inflate_workspacesize (err 0)
[   23.348293] btrfs: Unknown symbol zlib_inflateEnd (err 0)

It’s not btrfs related but any module with zlib_inflate in it’s dependency list.

I suspect it should not happen. ethernet device should not react to change of link state on particular switch ports
