Description
sys_str2addr() converts a string address representation to the sockaddr
structure. However, an invalid address sets either AF_INET or AF_INET6
address family and returns corrupted IP portion of the sockaddr object.
Return AF_UNSPEC address family in case of an invalid IP address. So,
default gateway detection can handle address parsing.
Invalid port portion is still silently ignored. In the future, the
function should return the conversion status and this needs to be
handled explicitly by the function users.
sys_gateway() converts string address to a temporary sockaddr object
on stack before changing the result object. However, a different
uninitialized object is checked for the conversion status.
Check the correct object.
