tipc: set sysctl_tipc_rmem and named_timeout right range
We find that sysctl_tipc_rmem and named_timeout do not have the right minimum setting. sysctl_tipc_rmem should be larger than zero, like sysctl_tcp_rmem. And named_timeout as a timeout setting should be not less than zero. Fixes: cc79dd1ba9c10 ("tipc: change socket buffer overflow control to respect sk_rcvbuf") Fixes: a5325ae5b8bff ("tipc: add name distributor resiliency queue") Signed-off-by: Jie Liu <liujie165@huawei.com> Reported-by: Qiang Ning <ningqiang1@huawei.com> Reviewed-by: Zhiqiang Liu <liuzhiqiang26@huawei.com> Reviewed-by: Miaohe Lin <linmiaohe@huawei.com> Signed-off-by: David S.
