Subject: ip6_udp_tunnel fails to load
Date: Tue, 23 Sep 2014 18:21:17 +0300	[thread overview]
Message-ID: <54218FED.4080102@dev.mellanox.co.il> (raw)

Hello Andy,

Lately I've start to observe a phenomena where the mlx4_en driver
couldn't load on my system as a result of an 'Unknown symbol in module'.

[ 1277.458715] ip6_udp_tunnel: Unknown symbol ip6_local_out (err 0)
[ 1277.486810] ip6_udp_tunnel: Unknown symbol __put_net (err 0)

Apparently, the mlx4_en driver is depend on the vxlan driver, which
depends on the ip6_udp_tunnel module which fails to load.

1. I've bisected this issue down to the following commit:
fd38441 udp_tunnel: Seperate ipv6 functions into its own file.

2. on a different host with a different .config, the module is loads
cleanly.

3. my sources are based on net-next commit
6d967f8 udp_tunnel: Only build ip6_udp_tunnel.c when IPV6 is selected

I'll send you both of the .config files in a private message.

This issue is making any driver which is depend on vxlan/ip6_udp_tunnel
unusable, please take a look and fix

Best Regards,
Eyal.
