Without this patch, we always set the BGP Prefix SID attribute flag without checking if it's malformed or not. RFC8669 says that this attribute MUST be discarded. Also, this fixes the bgpd crash when a malformed Prefix SID attribute is received, with malformed transitive flags and/or TLVs.

If we receive an attribute that is handled by bgp_attr_malformed(), use treat-as-withdraw behavior for unknown (or missing to add - if new) attributes. Signed-off-by: Donatas Abraitis <[email protected]>
