[Kernel-packages] [Bug 1743279] Re: QCA6174 stops working on newer kernels after second group rekeying
Hi there, AceLan, I've subscribed you to this bug because of 1) I've noticed you reported another bug, which had a fix submitted to xenial-proposed a few days ago, and I'm looking for some guidance here on how to have this bug fixed ASAP (even by me, if it means creating and submitting a new package myself or something like that, as per Ubuntu's documentation on fixing bugs) and 2) You're probably affected by it, if you own a QCA6174 and you're using a kernel later than 4.12. I'd consider this bug a high priority one because it directly affects users (and in a very significant way), it's been already fixed in upstream since October 2017 and porting the fix to Ubuntu would be trivial, I guess. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1743279 Title: QCA6174 stops working on newer kernels after second group rekeying Status in linux-firmware package in Ubuntu: Confirmed Bug description: After upgrading to the 4.13 kernel on Ubuntu 16.04.3, I've noticed my WiFi would stop working after every 20 minutes or so.

@Seth I just confirmed that it does fix the bug. I forced the re-installation of version 1.157.14 and rebooted. I checked that the old firmware was loaded and that the files in the /lib/firmware/ath10k/QCA6174/hw3.0/ folder were indeed the ones that came with the old package. Then I let the bug happen, which it did. Then I downloaded your package and installed it with dpkg.

[Kernel-packages] [Bug 1743279] Re: QCA6174 stops working on newer kernels after second group rekeying

The problem initially seems related to some DNS services crashing because of what happend in browsers and other software that usually rely on DNS but I've noticed I couldn't ping my router and other local devices for which I knew the IP addresses. The connection is still presented as being connected, but it just doesn't work. After googling a lot, I came across this question on askubuntu.com https://askubuntu.com/questions/967355/wifi-unstable- after-17-10-update Which led me to this bug report on Debian's bug tracker: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=879184 Which led me to this bug in upstream: http://lists.infradead.org/pipermail/ath10k/2017-September/010088.html I've tested the proposed fixes myself and I can confirm they work. What causes the WiFi to stop working is a bug related to the group rekeying routines. It seems it only happens in >4.12 kernels, hence why I've only had problems after 4.13 was pushed as the current rolling HWE kernel for 16.04.3. kvalo made the fix available in version WLAN.RM.4.4.1-00051-QCARMSWP-1 of the firmware-6.bin file, which is the current one present in upstream. Updating the firmware-6.bin (and board-2.bin, optionally) to any version equal or later than that fixes the issue completely. - SRU Justification: [Impact] Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter, available in numerous laptops, including ones that ship with Ubuntu 16.04 pre-installed, silently stops working after the second group rekeying, which is usually few minutes after the user has connected to a WiFi network. The connection status remains unchanged but there's no connectivity at all. This effectively disconnects the user without notifying it of what's occurred. Additionally, this happens for the only HWE kernel that's been patched against the recent Meltdown vulnerability, leaving the user without the option of using a recent kernel and a secure kernel at the same time.
