ROHC tunnel : decompression of packet #1 failed

[tsg321]

I have downloaded the latest ROHC and successfully build it using the following link.
https://rohc-lib.org/wiki/doku.php?id=library-install-sources

To test ROHC tunnel application, I have configured two PC with the steps mentioned in the following link
https://rohc-lib.org/wiki/doku.php?id=rohc-tunnel

First PC
modprobe tun
rohctunnel rohc0 udp remote 10.244.0.251 local 10.244.0.187 port 5000
ip link set rohc0 up
ip -4 addr add 10.0.0.1/24 dev rohc0

Second PC
modprobe tun
rohctunnel rohc0 udp remote 10.244.0.187 local 10.244.0.251 port 5000
ip link set rohc0 up
ip -4 addr add 10.0.0.2/24 dev rohc0

Once ROHC tunnel is configured, I ran ping application. Packet is being received on the other side but ROHC tunnel application is getting an error "decompression of packet #1 failed" and crashes. I am using ubuntu 14.04

I am unable to figure out why decompression failing ??

Hello,

This is probably the same problem as the one fixed there: https://github.com/didier-barvaux/rohc/commit/d9cdeb3be4bf744c5d20dbc5ec365d4fac89b31d

Try with the latest version on the 1.7.x branch, it contains fixes since the 1.7.0 release. Either get it with Git from https://github.com/didier-barvaux/rohc.git or simply download the following ZIP file https://github.com/didier-barvaux/rohc/archive/1.7.x.zip

Tell me if it fixes your problem.

Regards,
Didier
