sd_dhcp_client_set_client_id() is the only API for setting a raw client-id.
All other setters are more restricted and only allow to set a type 255 DUID.
Also, dhcp4_set_client_identifier() is the only caller, which already
does:
r = sd_dhcp_client_set_client_id(link->dhcp_client,
ARPHRD_ETHER,
(const uint8_t *) &link->mac,
sizeof(link->mac));
and hence ensures that the data length is indeed ETH_ALEN.
Drop additional input validation from sd_dhcp_client_set_client_id(). The client-id
is an opaque blob, and if a caller wishes to set type 1 (ethernet) or type 32
(infiniband) with unexpected address length, it should be allowed. The actual
client-id is not relevant to the DHCP client, and it's the responsibility of the
caller to generate a suitable client-id.
For example, in NetworkManager you can configure all the bytes of the
client-id, including such _invalid_ settings. I think it makes sense,
to allow the user to fully configure the identifier. Even if such configuration
would be rejected, it would be the responsibility of the higher layers (including
a sensible error message to the user) and not fail later during
sd_dhcp_client_set_client_id().
Still log a debug message if the length is unexpected.
