Summary - GRE tunnels dont work
Task Type - Bug Report
Category - Kernel
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - lede-17.01
Due in Version - Undecided
Due Date - Undecided
Details - LEDE version: 17.01.4, r3560-79f57e422d
BusyBox v1.25.1
Device: TP-Link TL-WDR3600 v1

Steps to Reproduce:
- Installed gre module with: opkg install gre mod-gre
- Added gre interfaces to /etc/config/network as following:

config interface 'gre0'
        option proto 'gre'
        option ifname 'gre0'
        option peeraddr 'myfqn.example.com'
        option mtu '1476'

config interface 'gre0_static'
        option proto 'static'
        option ifname '@gre0'
        option ipaddr '192.168.0.2'
        option netmask '255.255.255.252'

- When I try to ping the other side of the tunnel with: "ping 192.168.0.1"

root at lede-router:/etc/config# ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
ping: sendto: Invalid argument

Have tried already to run just with kmod-gre package install and get the same result.

When I install the gre package with: "opkg install gre" I get the following output from logread:

Sun Jan  7 03:25:05 2018 daemon.notice netifd: Interface 'gre0' is now down
Sun Jan  7 03:25:05 2018 daemon.notice netifd: Interface 'gre0' is setting up now
Sun Jan  7 03:25:05 2018 daemon.notice netifd: gre0 (3448): ./gre.sh: eval: line 1: resolveip: not found
