ip: fix unformat_ip_address forcing version to IP4 for some IP6 addresses
dd2f12ba made use of ip46_address_is_ip4() in order to determine whether the address is ipv4 or ipv6 within unformat_ip_address - however, its logic is correct only for some addresses. e.g. a valid IPv6 address of :: (unspecified) will result in "true" result. This is probably not an issue for most of the cases (the unspecified address is quite rare), however if the unformat_ip_address is used as part of the prefix parsing, the ::/0 is a fairly often utilized construct, which gets parsed as 0.0.0.0 Solution: return the old logic, but use a temporary variable to avoid overwriting the target memory on failure. Type: fix Fixes: dd2f12ba6ab952d9d66f4d9ba89ffde6309b1ff2. Change-Id: I272f740dfdf07036cec68516e153f0701a53233d Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
