Example:
# iptables -N 'hog wash'
# iptables -A INPUT -j 'hog wash'
iptables v1.4.20: Invalid target name `hog wash'
Try `iptables -h' or 'iptables --help' for more information.
Code:
static const char *
parse_target(const char *targetname)
{
...
for (ptr = targetname; *ptr; ptr++)
if (isspace(*ptr))
xtables_error(PARAMETER_PROBLEM,
"Invalid target name `%s'", targetname);
Conclusion:
It seems pointless to allow adding chains which cannot actually be used.
