From c899710fe7f9f24dd77135875f199359f7b8b774 Mon Sep 17 00:00:00 2001 From: Joel Granados Date: Wed, 9 Aug 2023 12:50:03 +0200 Subject: networking: Update to register_net_sysctl_sz Move from register_net_sysctl to register_net_sysctl_sz for all the networking related files. Do this while making sure to mirror the NULL assignments with a table_size of zero for the unprivileged users. We need to move to the new function in preparation for when we change SIZE_MAX to ARRAY_SIZE() in the register_net_sysctl macro. Failing to do so would erroneously allow ARRAY_SIZE() to be called on a pointer. We hold off the SIZE_MAX to ARRAY_SIZE change until we have migrated all the relevant net sysctl registering functions to register_net_sysctl_sz in subsequent commits. An additional size function was added to the following files in order to calculate the size of an array that is defined in another file: include/net/ipv6.h net/ipv6/icmp.c net/ipv6/route.c net/ipv6/sysctl_net_ipv6.c Signed-off-by: Joel Granados Signed-off-by: Luis Chamberlain --- net/mptcp/ctrl.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'net/mptcp') diff --git a/net/mptcp/ctrl.c b/net/mptcp/ctrl.c index ae20b7d92e28..43e540328a52 100644 --- a/net/mptcp/ctrl.c +++ b/net/mptcp/ctrl.c @@ -150,7 +150,8 @@ static int mptcp_pernet_new_table(struct net *net, struct mptcp_pernet *pernet) table[4].data = &pernet->stale_loss_cnt; table[5].data = &pernet->pm_type; - hdr = register_net_sysctl(net, MPTCP_SYSCTL_PATH, table); + hdr = register_net_sysctl_sz(net, MPTCP_SYSCTL_PATH, table, + ARRAY_SIZE(mptcp_sysctl_table)); if (!hdr) goto err_reg; -- cgit v1.2.3
