Subject: [142/151] ipvs: zero usvc and udest
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Simon Horman <horms@...ge.net.au>
commit 258c889362aa95d0ab534b38ce8c15d3009705b1 upstream.
Make sure that any otherwise uninitialised fields of usvc are zero.
This has been obvserved to cause a problem whereby the port of
fwmark services may end up as a non-zero value which causes
scheduling of a destination server to fail for persisitent services.
As observed by Deon van der Merwe <dvdm@...teq.co.za>.
This fix suggested by Julian Anastasov <ja@....bg>.
For good measure also zero udest.
