Date: Mon, 27 Jan 2014 11:49:02 +0800 From: Wang Weidong <wangweidong1@...wei.com> To: <nhorman@...driver.com>, <davem@...emloft.net>, <vyasevich@...il.com> CC: <dborkman@...hat.com>, <netdev@...r.kernel.org> Subject: [PATCH 1/2] sctp: fix a missed .data initialization As commit 3c68198e75111a90("sctp: Make hmac algorithm selection for cookie generation dynamic"), we miss the .data initialization. If we don't use the net_namespace, the problem that parts of the sysctl configuration won't be isolation and won't occur. In sctp_sysctl_net_register(), we register the sysctl for each net, in the for(), we use the 'table[i].data' as check condition, so when the 'i' is the index of sctp_hmac_alg, the data is NULL, then break. So add the .data initialization.
