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/rds/tcp.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'net/rds') diff --git a/net/rds/tcp.c b/net/rds/tcp.c index c5b86066ff66..2dba7505b414 100644 --- a/net/rds/tcp.c +++ b/net/rds/tcp.c @@ -565,7 +565,8 @@ static __net_init int rds_tcp_init_net(struct net *net) } tbl[RDS_TCP_SNDBUF].data = &rtn->sndbuf_size; tbl[RDS_TCP_RCVBUF].data = &rtn->rcvbuf_size; - rtn->rds_tcp_sysctl = register_net_sysctl(net, "net/rds/tcp", tbl); + rtn->rds_tcp_sysctl = register_net_sysctl_sz(net, "net/rds/tcp", tbl, + ARRAY_SIZE(rds_tcp_sysctl_table)); if (!rtn->rds_tcp_sysctl) { pr_warn("could not register sysctl\n"); err = -ENOMEM; -- cgit
