[LEDE-DEV] [BUG] Kernel crashes with ath10k radio and Nexus 5X clients

[Timo Sigurdsson]

Hi everybody,

I have a TP-Link Archer C7 v2 running a fairly recent build of LEDE (r1952, 
Linux 4.4.26, compat-wireless-2016-10-08). It all works well except for the
fact that when I connect a Nexus 5X device to the 5GHz radio, the kernel or
ath10k driver will crash after a while. 5Ghz wifi will be dead after that
until I reboot the system.

This issue has been reported before [1] and it also has been declared as
solved with newer firmwares [2] (but reopened by other users). However, even
with the latest firmware 10.2.4.70.58 from Kalle Valo's Github repository the
issue is far from resolved. I have tried many different firmware revisions
over the time (more recently 10.2.4.70.56 and 10.2.4.70.54), and I can could
only find that the issue sometimes takes longer to trigger with some firmwares
(which might just be random), but it would always occur at some point with API
level 5 firmwares. With API level 2 firmwares (which I testesd when I was
still using OpenWrt 15.05) I never saw these crashes, but the Nexus 5X had
other connectivity issues with these older firmwares that made this
combination no fun to use either. But this shows that the firmware itself
makes the difference here.

I actually have two Nexus 5X on my network (my wife's and my own). I can
trigger the crash with either one of them. And if both Nexus 5X are connected
to the 5Ghz radio, then the issue triggers much faster (can be as low as 15
minutes). My workaround is to let the Nexus 5X devices only connect to the
2.4GHz radio. This way, the device can runs for weeks without any issue or
crash, but of course I would prefer the actual bug being fixed rather than to
circumvent it.

I'm appending a syslog from my access point with a crash happening while one
Nexus 5X was connected to the 5GHz radio starting from the time the system
booted. I randomized the MAC addresses. but left the first two characters
unique so different clients can be distinguished.

If there is more info I could collect to help identify the cause of this
issue, please let me know (and possibly how to do that as well).

Thank you and regards,

Timo

Not much. There are now just four "Mode Mismatch Interrupt" instead of five.

I did a short 400MiB read speed test from a fast usb stick.
The dwc2 driver (with the param_ltq values) is faster than 
ifxhcd.

ifxhcd:
real 0m 23.26s
user 0m 0.01s
sys 0m 15.18s

dwc2:
real 0m 16.31s
user 0m 0.00s
sys 0m 8.38s

Christian

Ok, Thanks, I guess this should work fine if you follow through with 
phasing out the old driver too (Yay for that!). The 
"lantiq,ifxhcd-danube" will take preference as it is the first entry,
but that's fine.

I tested the patch on my EasyBox 802 (Arcadyan ARV752DPW).

[6.294998] dwc2 1e101000.ifxhcd: Configuration mismatch. Forcing host mode
^^

This can be fixed by setting dr_mode to host in the DTS.

The generic dwc2 defaults to OTG mode (as per generic.txt) [0].
(Well, technically, it's UNKNOWN at first but here's the logic [1]).

I don't think these are much of an issue. At least for this device the ifxhcd 
driver
also produces the same messages. For example, this is an extract bootlog from 
the
opernwrt wiki [2].

Now, there has been recent changes to dwc2 which might fix these pesky
errors. The discussion can be found on the LKML [3] and three patches
were committed to 4.9-rc.

usb: dwc2: Properly account for the force mode delays [4]
usb: dwc2: Add delay to core soft reset [5]
usb: dwc2: gadget: Only initialize device if in device mode [6]

I'll give then a try and see test if they help. Otherwise:

[LEDE-DEV] lots of broken packages

[Torbjorn Jansson]

Hello

looks like there are lots of broken packages currently.
was going to install i2c-tools but it looks like it failed with lots of 
messages like:


include/linux/i2c-dev.h:156:21: warning: inlining failed in call to 
'i2c_smbus_access': call is unlikely and code size would grow [-Winline]
 static inline __s32 i2c_smbus_access(int file, char read_write, __u8 
command,


is this a case of problem already known and i just have to wait a bit 
and it will get fixed by itself?


i'm currently testing something and i need i2c tools.
then later i probably need to read up how the building of primarily the 
kernel is done so i can add a few missing kernel modules.

Arch Linux also uses gcc 6:
$ gcc --version
gcc (GCC) 6.2.1 20160830

with your little test:
$ echo 'int main(int a, char **v) { gzdopen(0, "rb"); return 0; }' |
  gcc -include zlib.h -x c -o test - -Wl,-Bstatic -lz -Wl,-Bdynamic
$ echo $?
0

I have not tested the buildroot though

No, sorry. I was testing the wrong build. I'm afraid "snps,dwc2" doesn't
work after all. It tries to autodetect the parameters, doesn't log any
errors, but then doesn't recognise devices which are plugged in, 
so presumably the parameter values it thinks it has detected are
not correct.

What do you think would be the best thing to do, stick with my original
patch set using the same parameters as for arx and vrx, which appear
to work fine, or investigate the ifxhcd code and add a separate 
dwc2_core_params structure called params_danube with (possibly) bigger
fifos? I'd prefer the former for simplicity's sake.

Thanks again,

Ben

We have to start somewhere, and having the technical base available to
actually build releases is a good first step.

I agree that eventually there needs to be a release engineering team but
it makes no sense to have that in place when nobody is actually able to
build releases. Also code freezes or branches make less sense when no
one is able to produce suitable, updated binary artifacts - that is the
main reason why we try to solve the technical hurdles first.

I will feel much more confident about this once we actually did a
release test (means a test on how to build a binary release, not a
release for testing binaries) - then we can start planning schedules.

In the past, building OpenWrt binary releases was a painful, manual and
time consuming task which took between 4 to 8 weeks to pull of.

Help is pretty much appreciated in, any direction :)

I cannot tell much about Gluon, I never used it myself but I did notice
that it has a rather continuous and solid development model. Also with
Matthias on board I am confident that some experience can be shared here
in the long run.

Sure, it might make sense to leverage synergies here (sorry for the BS
phrase) but for example I think that Gluon has a good testing exposure
and valuable community feedback which are things LEDE can certainly
benefit from.

I'm sure some people will attend the 33c3 - for the rest we can maybe
stage a video conference or something to exchange ideas. Personally I'll
likely not able to be there but I would appreciate some discussions
nonetheless.

You are right. It works fine with "snps,dwc2". (Apart from the same
mode mismatch warnings) When I tried that before I didn't have the
benefit of your hardware initialisation code and my own version
must have been wrong.

I'll submit a version 2 patch set.

Uhm, I think you are wrong.
In OpenWRT/LEDE applications that don't need root access are run as 
unprivileged users for security reasons, so yes, a privilege escalation 
is BAD also for OpenWRT/LEDE.

root@lede:/# cat /etc/passwd
root:x:0:0:root:/root:/bin/ash
daemon:*:1:1:daemon:/var:/bin/false
ftp:*:55:55:ftp:/home/ftp:/bin/false
network:*:101:101:network:/var:/bin/false
nobody:*:65534:65534:nobody:/var:/bin/false
dnsmasq:x:453:453:dnsmasq:/var/run/dnsmasq:/bin/false

And for LEDE the answer to the vulnerability was "finish the porting to 
latest kernel 4.4 for all devices ASAP as that kernel is a LTS kernel so 
it received the fix upstream, and apply patches to other kernels", see 
these mailing list posts:
http://lists.infradead.org/pipermail/lede-dev/2016-October/003579.html
http://lists.infradead.org/pipermail/lede-dev/2016-October/003580.html

So current LEDE is already protected, I don't know if this stuff also 
ends in OpenWRT.

Depends :-).
OpenWRT has a big package repository, offering dozens applications. I
guess, that you're right for about > 80% of all OpenWRT users, but there
are others. As far as I'm aware of, discussions on CVE-2016-5195 are
taking place  https://forum.openwrt.org/viewtopic.php?id=68181 so some
people do care - some discussions are happening on openwrt-dev, too.

However, I'm neither interested in discussing the impact of a local root
exploit, nor the urgency for this kind of fix.

I'm trying to estimate the liveliness and its future impact for OpenWRT.
Take
https://lists.openwrt.org/pipermail/openwrt-devel/2016-July/041987.html
for instance.
Please don't get me wrong: I'm not saying that OpenWRT is unable to do
releases, but "KanjiMonster" statements, make me worry about the shape
of OpenWRT-Setup when something bigger happens.

Greetz, yanosz

I think 2 GB is excessive. Due to the way that sysupgrade works, having
such a large rootfs partition is often not very useful anyway, since
everything except for config files gets lost.
It significantly increases build time and the amount of time it takes to
transfer an image to a flash medium.

In my opinion it's much more useful to keep the rootfs small and add a
data partition covering the rest of the medium, which then gets
preserved across upgrades.

[LEDE-DEV] buildroot broken on debian jessie

[Dirk]

Hi,

something scrumbled my formerly working LEDE buildroot environment.
I'm using debian testing/jessie as host - see output below.
The static zlib package (zlib1g-dev) is installed and the library is
located in /usr/lib/x86_64-linux-gnu/libz.a.
Any idea how to nail down this problem?

Thanks!
Dirk
