[lustre-devel] lnet ip2nets option broken in master?

Hi all,

I'm doing several tests with LNET and I realized lnet module option 'ip2nets' does not work anymore.
I git-bisected the regression down to:

commit f5991afd8779fe747778e28e998277a10242a57d

    LU-11838 lnet: change lnet_ipaddr_enumerate() to use for_each_netdev()

Am I doing something wrong? Is that already known and there is some patchs around for it?

Funny thing is that the normal way to use it does not work, but if I specify IP address in the reverse order, it works. (Could be just a side effect/red herring)

Ie: ip2nets="tcp2(eth0)".  -> ERROR (correct IP)
ip2net="tcp2(eth0)" -> OK

I was not able to understand the bug.

If it makes sense, I can open a ticket.
