Created attachment 282741 [details] A snippet from dmesg logs I have a Dell Latitude 5591 laptop with Intel Wireless-AC 9560 wifi card. Using kernel 5.0.13 on Fedora 30 distro. Loaded firmware is iwlwifi-9000-pu-b0-jf-b0-43.ucode On a certain Wifi Access Point I'm getting my dmesg log spammed with iwlwifi 0000:00:14.3: Unhandled alg: 0x707 messages (like 20 every second). Wifi works well during that, but system freezes irrecoverably after approximately an hour passes (maybe some memory limit for dmesg log size?). Magic sysrq key doesn't work after it freezes. Changing access point to a different one helps - dmesg goes silent. This different access point runs on the same router as the misbehaving one, so it's hardware is not the issue. There is a different laptop of the same model and same hardware running Ubuntu 18.04 LTS release with 4.18.5 kernel and does not have this issue on these same access points. Also attached a snippet from dmesg logs.
What access point is that?
It's a 5ghz 11ac access point. Don't know any more details, because it's my workplace access point and admins won't give much info about it
Some additional details: both AP's seems to be mesh-networks (there seems to be 4-5 cells with the same ssid but different mac addresses). Both working and non working AP's have cells with the same frequency and mac address. They are both using IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : PSK And also I have tried to iwlwifi module options 11n_disable=1 and disable_11ac=1 separately and together to use 11g or 11n or 11ac exclusively. That made no change
Created attachment 282909 [details] iwlwifi FW with debug configuration
Created attachment 282911 [details] Debug collection patch
Hi, If you can, it would be useful for our debugging if you could collect some additional data data: 1. Please have a look at the following link which describes how to collect additional debug data: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging#firmware_debugging 2. Please take the time to read our privacy note here: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging#privacy_aspects 3. If you can, use the attached fw, which includes debug data configuration. 4. If you can compile your costume kernel, apply the attached patch. With the attached patch there is no need to manually trigger the debug data collection. 5. It would be very useful if you could also capture kernel traces: - install trace-cmd: yum install trace-cmd - Run: trace-cmd record -e cfg80211 -e mac80211 -e iwlwifi -e iwlwifi_data - Once done, send us the trace.dat file - Note that using '-e iwlwifi_data' would capture all data traffic so you might want to skip data. Thanks in advance, Ilan.
I get this when trying to apply the patch: >Applying: iwlwifi: mvm: Trigger debug collection on unhandled algorithm >error: patch failed: drivers/net/wireless/intel/iwlwifi/fw/error-dump.h:500 >error: drivers/net/wireless/intel/iwlwifi/fw/error-dump.h: patch does not >apply >error: patch failed: drivers/net/wireless/intel/iwlwifi/mvm/rx.c:8 >error: drivers/net/wireless/intel/iwlwifi/mvm/rx.c: patch does not apply >Patch failed at 0097 iwlwifi: mvm: Trigger debug collection on unhandled >algorithm Can you help with getting this patch ready for kernel version 5.0.16?
sure ... I'll try to get it later today or tomorrow morning. Ilan.
Created attachment 282919 [details] Driver patch to force FW crash on unhandled algorithm Sorry I got delayed with this. The patch would cause a FW NMI, which would crash the FW and trigger debug data collection, thus, please make sure that u set the following option in '/etc/modprobe.d/iwlwifi.conf': options iwlwifi fw_restart=0 Thanks, Ilan.
Hi, when using this patch, do I need to have any debugging options enabled in kernel? Do I need to load debug firmware you've provided? Will dmesg output after crash be enough?
No other debugging options are need with this patch, but please use the FW I provided yesterday. If you are going to provide trace-cmd data, then you should enable CONFIG_IWLWIFI_DEVICE_TRACING and enable kernel traces.
Created attachment 282931 [details] iwlwifi debug fw crash log Added a crash log with debug firmware
We'll need the firmware dump that was created if you followed the instructions from the wiki page. Thank you.
Ah, sorry, I can do that only on monday
Created attachment 282947 [details] encrypted dump Adding fw dump encrypted as per privacy instructions described here https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging#privacy_aspects
Thanks for the data. We are looking into it. Would it be possible to also share the syslog or at least the network wlan security configuration: which authentication method is used, and which cipher suite were used? Thanks, Ilan.
IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : PSK Is this info enough?
For now yes. Thanks.
Just a follow up - with Kernel 5.1.5 and firmware version 46 the problem is still present
Hi, Thanks for the update. We now have someone that is looking into the issue. Seems that the issue is with an encrypted multicast data frame that we do not decrypt. However, we still do not know why. I'll keep you updated once we have more. Thanks :) Ilan.
Created attachment 283171 [details] iwlwifi FW with more debug information Hi, Based on the dump you provided we suspect that the issue is caused since no GTK was installed (the key used to decrypt multicast data frames from the AP to the station), but we cannot determine why. Can you please reproduce with the attached FW and in addition also provide trace-cmd data (as specified earlier)? Providing trace-cmd is important since it would allow us to determine if the GTK was configured by the supplicant/driver or not. Thanks in advance, Ilan.
Hi, Just to clarify. Please reproduce with kernel 5.1 and with my patch. Ilan.
Created attachment 283175 [details] encrypted dump 2 Adding dump from kernel 5.1.7 with 46 debug firmware
Created attachment 283177 [details] encrypted trace.dat Adding trace.dat from kernel 5.1.7 with 46 debug firmware
The parsed trace-cmd shows that following a successful connection establishment, after about 1 sec, the wpa_supplicant decided to deauthenticate from the AP, for an unknown reason (reason code in the deauthentiction frame is 3 == leaving). After the deauthentication, the wpa_supplicant issues as scan, and then tries to connect to the same AP, sending an authentication frame. However, before the authentication is complete, the FW forwards to the driver a multicast data frame which it was not able to decrypt (which is expected, as no keys were installed at this stage), and thus we get the "unhandled alg 0x707" message ... which is not really an error message.
Created attachment 283189 [details] Fix multicast frame forwaring Can you please try the attached patch. As explained earlier, the driver configured the FW to pass multicast data frames before actually being able to handle them. This patch attempts to fix this (although such frames might still get to the driver after the association is complete but before the keys were installed). More interesting would be the reason why the wpa_supplicant decided to deauthenticate from the AP, so if you can in your next reproduction please also provide (in addition to trace-cmd, dmesg and FW dump) wpa_supplicant logs (they should be available in the syslog).
I can clarify the deathentication: In order to collect this trace data I had to do the following: 1. rmmod iwlmvm && rmmod iwlwifi (it has crashed before and did not restart automatically) 2. modprobe iwlwifi (it started connecting to "BAM" AP which does not trigger the 0x707) 3. I manually disconnected from "BAM" AP (3 == leaving) and selected "BAW" AP to connect to The reason you thought it was the same AP is that both BAM and BAW AP's share the same MAC address and are served from the same router
This might also explain all the 0x707 messages :) You have two APs configured with the same MAC address, so while the station is connected to AP1, it would still filter in multicast frames from AP2, but since AP2 uses a different key to encrypt them the station is not able to decrypt them .. and thus the error messages. Does this make sense, or did you also get these messages in other scenarios?
This makes sense, but doesn't explain why the second AP doesn't generate these messages...
Maybe this is because when you are connected to the "good AP" the other AP does not have any stations associated with it so it does not transmit any multicast frames. Regardless, can you confirm that this issue is not seen when the 2nd AP is turned off/on a different channel?
Created attachment 283193 [details] iwlist scan encrypted Sorry, I have no control on these AP's being on or off. Providing iwlist scan results listing all AP nodes if these are any help. And will try your patch as well
Hi, Are u sure that "BAM" and "BAW" share the same MAC address? Seems to me that although the address are very similar there is at least 1 bit different between the addresses. At least the scan list that you attached does not have duplication of MAC addresses. Ilan.
Actually...You are right. MAC addresses are similar, but not the same
ok. So at least this is not the issue. Are u sure that the disconnection is done by u? It seems very fast after the initial connection.
I've tried to do it as fast as I can. Finishing building kernel with your patch, will test this again
Created attachment 283195 [details] encrypted dump 3 this is from the run with the patch applied

So now I disabled auto connect and recorded without manual disconnect, as clean as I could
Hi, Based on the debug data you collected, it seems that the patch I send was not used. Can you please double check that you are running a driver with the patch? Thanks, Ilan.
Hi, I've rebuilt the kernel, from build logs I saw the patch applied. After I've built the kernel, I've installed resulting RPMs with rpm -i --force option (as version were the same). Is there any way to find out if the patch was applied from the .ko file that is installed?
Not really ... I'll prepare the same patch with some prints. Will upload in few minutes.
Created attachment 283231 [details] Fix multicast frame forwaring with prints This is the same patch as the previous + print. Give it a try :) You should see: "Setting mcast filter"
One small question - does the patch that crashes driver on 0x707 error have to be applied as well? Or this last one only?
Either you use both patches, or you use only the new one and manually trigger debug dump. Better use both. Ilan
Created attachment 283241 [details] encrypted trace.dat 3 trace.dat with both patches
Created attachment 283243 [details] encrypted snippet from journalctl logs 2 with both patches
So I've deleted everything that I've compiled before, applied both patches, installed kernel and tried to connect to this "broken" AP - firmware didn't crash, logs are not being spammed. Will use this kernel for the day to make sure the system freeze doesn't happen as well. But looks like this helped :)
Created attachment 283251 [details] encrypted dump 4 An hour has passed (when the system used to freeze) and wifi driver has crashed again (but without freeze this time). I collected a dump and journalctl log (I see 0x707 error in it again). Seems that there is some re-handshake or something like that happening during the time. Don't know how to capture trace-cmd without a loot of useless info captured as well
Created attachment 283253 [details] encrypted snippet from journalctl logs 3
hi, This looks like a different problem. From the debug dump it looks like the AP started sending multicast frames using key index == 2 (before that it was using key index == 1). The AP probably performed a GTK rekeying, but based on the dump, the new key was not propagated to the FW, so it fails to decrypt the multicast frame. I cannot say why the key was not programmed to the FW. It is possible that the AP performed the GTK rekey while the station was asleep so it missed this frames. If this is the case then this is a bug on the AP side. I'll need to double check this assumption with some other guys (but that would probably happen only next week ... sorry). For now I suggest that you work only with the 1st patch applied. Thanks again for all your help, Ilan.
Another option, and a better one :) Can you run with power save disabled? In "/etc/modprobe.d/iwlwifi.conf" add: options iwlmvm power_scheme=1 This would disable powersave. Ilan.
Disabling powersave helped, now the firmware doesn't crash :) And by saying that I should work with the 1st patch applied - do you mean the one that kills the driver on 0x707 or the one that filters multicast frames? Anyways, thanks for the support and for solving this problem for me :) Can I expect mcast filtering to land in the mainline kernel?
Hi, Work only with the mcast filtering. The other patch was only to simplify the FW debug data collection. The mcast filtering patch would make its way to mainline kernel as with other bug fixes. FWIW, we are still troubled with the AP behavior during GTK rekeying, as it seems that it completed the GTK rekeys without our device being aware of it. Can you please share the AP details (HW model, chipset and FW version) so we might be able to further investigate this? Thanks for all your help :) Ilan.
So I got the following info about our AP: Model: UniFi AP-AC-Pro, Version: 4.0.42.10433, Board Revision: 26 Should be running with this chipset: Qualcomm Atheros QCA9563 (taken from https://oldwiki.archive.openwrt.org/toh/ubiquiti/unifiac) but it's not running openwrt, it's running stock firmware
Thanks for the info! Ilan.
It turns out that our AP's got upgraded to 4.0.42 version quite recently and it looks like it really helped. Still getting occasional 0x707, but no spamming and no freezes even on vanilla 5.1.9 kernel without powersave off (debug firmware though).

Hi, Good to hear :) As I describe above we indeed suspected that the AP performed the GTK rekey while the station was in power save which is not valid. Just to be clear, your are getting the above without the patch that fixed multicast data handling. right? Thanks, Ilan.
Yes, this is on vanilla kernel from fedora repositories
Great :) A modified version of the fix I gave you will make it to the kernel tree soon. Regards, Ilan.
I am closing this. We will still see any comment you'll add here.
Can you add the SHA1 of the upstream patch that fixes this issue, please, so we can figure out which kernel versions contain it?
Hm... apparently Luca hasn't sent the fix upstream yet. You can find it here: https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git/commit/?id=2fc5847ec08431b1b6e04aa799db686f53eeb31c This is our backport based driver. Any patch here will eventually reach upstream. I typically handle the bugzilla issues (hopefully not for much longer..) and Luca handles the upstreaming work so that we're not always in sync..
How can one tell when the patch has been committed to the kernel? I'm still getting this, and losing wifi, on 5.3 branch.
