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") Signed-off-by: Christophe Leroy <christophe.leroy@xxxxxx> Signed-off-by: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- net/netfilter/nf_conntrack_sip.c | 2 -- 1 file changed, 2 deletions(-) --- a/net/netfilter/nf_conntrack_sip.c +++ b/net/netfilter/nf_conntrack_sip.c @@ -1630,8 +1630,6 @@ static int __init nf_conntrack_sip_init( ports[ports_c++] = SIP_PORT; for (i = 0; i < ports_c; i++) { - memset(&sip[i], 0, sizeof(sip[i])); - nf_ct_helper_init(&sip[4 * i], AF_INET, IPPROTO_UDP, "sip", SIP_PORT, ports[i], i, sip_exp_policy, SIP_EXPECT_MAX,
