Ezequiel Garcia 049bbf589e ipv4: Fix non-initialized TTL when CONFIG_SYSCTL=n ... Commit fa50d974d1 ("ipv4: Namespaceify ip_default_ttl sysctl knob") moves the default TTL assignment, and as side-effect IPv4 TTL now has a default value only if sysctl support is enabled (CONFIG_SYSCTL=y). The sysctl_ip_default_ttl is fundamental for IP to work properly, as it provides the TTL to be used as default. The defautl TTL may be used in ip_selected_ttl, through the following flow: ip_select_ttl ip4_dst_hoplimit net->ipv4.sysctl_ip_default_ttl This commit fixes the issue by assigning net->ipv4.sysctl_ip_default_ttl in net_init_net, called during ipv4's initialization. Without this commit, a kernel built without sysctl support will send all IP packets with zero TTL (unless a TTL is explicitly set, e.g. with setsockopt). Given a similar issue might appear on the other knobs that were namespaceify, this commit also moves them.
