Thanks for the backport - the retarget to nf_log_ipv4.c is right for 5.10.
One gap though: upstream fixed both loggers via the consolidated
nf_log_syslog.c, but in 5.10 the IPv6 logger (net/ipv6/netfilter/
nf_log_ipv6.c) still has the identical unguarded fallback and is left
vulnerable here - which is also Pablo's "why only 5.10?" point.
