4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe Leroy <christophe.leroy@xxxxxx>
commit da2f27e9e615d1c799c9582b15262458da61fddc upstream.
In commit 82de0be6862cd ("netfilter: Add helper array
register/unregister functions"),
struct nf_conntrack_helper sip[MAX_PORTS][4] was changed to
sip[MAX_PORTS * 4], so the memory init should have been changed to
memset(&sip[4 * i], 0, 4 * sizeof(sip[i]));
But as the sip[] table is allocated in the BSS, it is already set to 0
Fixes: 82de0be6862cd ("netfilter: Add helper array register/unregister functions")
