Re: [OpenWrt-Devel] shutting down gb10 soon from the build cluster

2016-07-28 Thread Zoltan HERPAI

Hi Dave,

Thanks for running and contribting gb10 up to this point - we have a 
thread going on with Travis about migrating off the buildmaster. I'm 
offline for a couple days, will be back around 6/Aug - so if you could 
keep the server running until 10/Aug it'd be greatly appreciated.


Thanks,
Zoltan H

It is still my hope that some sane way of funding the continuous
integration system and the maintainers of it emerges, as per this old
conversation here:

https://lists.openwrt.org/pipermail/openwrt-devel/2015-December/037781.html

but I've got to cut things back. It appears that the current openwrt
build cluster is sizeable enough for the load, currently, and gb10,
will not be especially missed.

[OpenWrt-Devel] [L2TP] Bad UDP Checksum on TP-LINK hardware

2016-07-28 Thread Leon George
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

Hi :-)

The UDP checksum for outgoing L2TP datagrams seems to be broken.
It has been tested with TP-LINK's WR842n, WDR3600, and WDR4300.
On two normal Linux computers it's working.

We've tried disabling UDP offloading using ethtool without success.

Is there any way we can make OpenWRT emit the datagrams with the
checksum in place?

This shows up in Wireshark. The first two datagrams are being received
on the other side. The ones after the l2tp aren't.

#this is received on the other end. normal udp
14.6944 UDP 575 52958 → 53201  Len=513
14.8159 UDP 152 53201 → 52958  Len=90
#ip l2tp add tunnel tunnel_id 52958 peer_tunnel_id 53201 encap udp
local '2001:920:18ae:3:20b:c0ff:fe46:42b0' udp_sport 52958 remote
'2a03:b0c0:3:d0::bb5:6001' udp_dport 53201
14.9130 UDP 184 52958 → 53201  Len=122 [ILLEGAL CHECKSUM (0)]
15.3230 UDP 152 52958 → 53201  Len=90 [ILLEGAL CHECKSUM (0)]
15.6929 UDP 184 52958 → 53201  Len=122 [ILLEGAL CHECKSUM (0)]
15.8198 UDP 164 53201 → 52958  Len=102

hoping somebody has an idea :-)

cu,
Leon
