[avahi] Testing required: new avahi patch to fix breakage from 0.6.15

[Trent Lloyd]

Howdy folks,

The new patch in 0.6.15 that checked the sending process of netlink
messages has turned out to be bogus and break in some cases, most
especially when using NetworkManager.

I have a new patch here
http://lathiat.net/avahi-0.6.15-checkcred.patch

Is everybody that is able/can/wants to, whether they had the problem or not,
able to test this? The most notable case to test is starting with the network
down, starting avahi, and then bringing the network up, this specific
case consistently broke with network-manager (easiest way to test is to
have another device on your network advertising, and see if it appears
in avahi-discopver)

If you can report if you had this problem with 0.6.15, and then if you
have this problem with this patch applied, and whether you are using
network manager or something else.

Of course, general testing of any scenario is welcomed to make sure this
patch doesnt break something else :)

If this patch does break something, please look for lines that say

Netlink message received from cred->uid != 0 (<UID)

And include that line (or specifically the value of <UID>)

Thanks :)

Trent

NOTE: Those compiling on 2.6.19 (e.g. Ubuntu Feisty) may wish to apply
