Date: Mon, 18 Nov 2013 14:33:13 +0000
Subject: [PATCH 03/17] fipvlan fails on powerpc
fipvlan fails to execute properly on powerpc architecture.
# fipvlan -a
Try 'fipvlan --help' for more information
#
# fipvlan --create --start eth1
Try 'fipvlan --help' for more information
#
In power pc systems, when there are no more arguments to be parsed, getopt_long
should return -1. But gdb output shows that it c is 255 whereas in intel system
it shows -1 properly.
"char" must not be trusted when signing is important! Different arches (and even
different gcc versions on the same arch) may default char to signed or unsigned.
Ideally, a portable program should always use signed char or unsigned char when
it depends on the signedness of an object. But many programs have been written
to use plain char and expect it to be signed, or expect it to be unsigned,
depending on the machines they were written for. In this case the variable c
is expected to behave as signed and hence using signed would be the safe option.

Subject: [PATCH 04/17] fipvlan: Only shutdown interfaces if no vlans are
created
Instead of having to check the individual stages we can
easier just check if any vlans are created. Vlans are
only created if the user specified '--create', so if
no VLANs are created either the user has not specified
it or some error occured along the line. In either case
we can shutdown the interface.

Instead of starting the VLAN interface after the call to
vlan_create() we should rather start it after the netlink
message has been received. Otherwise we have a race window
as we might try to start a network interface which isn't
present yet.

Subject: [PATCH 10/17] fipvlan: Re-send VLAN discovery
Some switches might decide to discard the VLAN discovery request,
so we should rather re-send it whenever we need to retry.
At worst we will be receiving several responses, but they'll be
discarded.

If we don't receive a SAN MAC address it's pointless to try
to create a socket, as FCoE itself cannot continue. So we
should be handling errors from socket creation and abort
VLAN discovery early.

From 6bde8d1b9f63a7d110fab53e3791040cbe9b101f Mon Sep 17 00:00:00 2001
From: Hannes Reinecke <hare@suse.de>
Date: Tue, 19 Nov 2013 20:26:14 +0000
Subject: [PATCH 17/17] fipvlan: filter interfaces from rtnl_getlink
Instead of carrying around two different ways on selecting
interfaces we should be filter the list of possible interfaces
during RTM_GETLINK / RTM_NEWLINK and use only one list.
This safes us from having implement two codepaths for doing
the same thing.
