[OpenWrt-Devel] Patch iwinfo to detect wrt3200acm chipsets

[Erik Andersen]

A small patch to iwinfo is needed to properly detect and report the
Marvell 88W8964 and 88W8887 chipsets in the wrt3200acm. This trivial
patch against the latest iwinfo git tree works for me.

This should be fixed in kernel 4.14.32. Try the latest snapshot.

[OpenWrt-Devel] [PATCH] mac80211: pass hostapd control socket to mesh-mode supplicant

[Daniel Golle]

Unlike when operating in Ad-Hoc mode, we apparently need to pass the
hostapd control socket interface to wpa_supplicant when using 802.11s
mesh mode.

There also seems to still be something wrong with the logic setting
channel and (v)htmode parameters when using AP + mesh...

Hi,

Thanks for the pointer. I compiled a new image KALLSYMS, but now I am
not able to reproduce the error. Perhaps there was something dirty in
my build directory. I will keep the image KALLSYMS on the routers and
keep checking for the error.

Re: [OpenWrt-Devel] Boot Time Reduction

Now as mentioned in previous mail only 
at that two locations I see some process consuming lot of time.

Is it possible to reduce the time consumed by the process?




Isn't the long time between pre-init and ubi mount due to the lengthy 
block scan that the ubi layer performs? In that case, switching to 
squashfs with optionally an overlay might reduce the mount time.

[OpenWrt-Devel] Wifi-related kernel-oops on mt7621 after 4.14 update

[Kristian Evensen]

Hello,

I have recently updated some ramips mt7621-devices (ZBT WG3526) to the
latest nightly. Almost everything seems to work fine, but using either
wifi interface in client mode seems triggers an oops. I see two
different oops-messages:
