Hi Ferruh

> Linville).
Sorry about that. I have 2 patches ( one for af packet, one for bonding).

I am a little confused.


> Can you please give more details, what is failing what is the impact etc.

In bond (lacp) we have several nics ( ports )

When we have negotiation with peer about what port we prefer,

we send information about what system we preferred in partner system 
name field.

Peer also sends us what partner system name it prefer.

When we receive a message from it we must compare its preferred

system name with our system name, but not with our port mac address

In my test I have several problems with that

1. If master port (mac address same as system address)

shuts down (I have two ports) I loose connection

2. If secondary port (mac address not same as system address)

receives message before master port, my connection is not established.

Hi Vadim,

Thanks for the info and sorry for late response, it is sitting in backlog for a
long time now.

@Chas, do you have any objection on the fix, if not I am planning to merge it soon.

Thanks,

cc'ed Xavier, he also has a bonding patch in the backlog waiting for review [1].


Vadim, Xavier,

Since you both send bonding patches, I assume you both know about bonding at
some level, at least more than me, so would you mind reviewing eachother's
patch? So both can go it.

Thanks,
ferruh

[dpdk-dev] [PATCH v3] net/bonding: fix LACP system address check

[Ferruh Yigit]

From: Vadim Podovinnikov <podovinnikov@protei.ru>

In bond (LACP) we have several NICs (ports), when we have negotiation
with peer about what port we prefer, we send information about what
system we preferred in partner system name field. Peer also sends us
what partner system name it prefer.

When we receive a message from it we must compare its preferred system
name with our system name, but not with our port mac address

In my test I have several problems with that:
1. If master port (mac address same as system address) shuts down (I
   have two ports) I loose connection
2. If secondary port (mac address not same as system address) receives
   message before master port, my connection is not established.

This patch is waiting for review for a long time, if there is no objection I am 
planning to get it early in the release to give it a time to fix any possible 
issues.
