* vxlan: properly handle LOOSE_COMPARISON in ->io_compareSabrina Dubroca2016-06-251-1/+1
| | | | | | | | This lets us match links only on the attributes that have actually been set, instead of comparing all attributes. Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Thomas Haller <thaller@redhat.com>
* pass flags through ->io_compare opSabrina Dubroca2016-06-252-3/+4
| | | | | | | | | | Currently rtnl_link_info_data_compare doesn't pass flags (LOOSE_COMPARISON) to the ->io_compare op, so we cannot do a match on only the attributes that are actually set in the filter object used in a cache lookup via nl_cache_find().

| | | | | | | | | | | Also check for NULL link and dereference link before basic error checking. Also move the declaration of the @sit member inside the macro. Obviously, the macro must now always come at first, after declaring local auto variables. Signed-off-by: Thomas Haller <thaller@redhat.com>
* sit: don't print ip6rd_prefix as integer in sit_dump_details()Thomas Haller2016-04-151-2/+2
| | | | | | | | | | | | | | First of all, inet_ntop() has no reason to fail (ever). As long as the input arguments point to valid data and family is not bogus. But when it fails, we cannot pass a 'struct in6_addr' to "%x" either, so just don't do that. Same for printing ip6rd_relay_prefix as AF_INET. If our addr-to-str method fails, we don't want to come up with something fancy. Otherwise, we'd just implement a inet_ntop() that does not fail. Signed-off-by: Thomas Haller <thaller@redhat.com>

* route/vlan: allow clearing vlan ingress mapThomas Haller2015-11-191-2/+16
| | | | | | | | | | | | | | | | | | | | | An entry of the ingress map can be cleared by setting the "to" part to zero. Previously, vlan_put_attrs() would skip over zero "to" and thus the user cannot unset an ingress map entry. Add a modified-mask to record the state of each ingress map entry and also sent explicit zeros to kernel. when we receive a IFLA_VLAN_INGRESS_QOS message from kernel, vlan_parse() similarly sets the received entries as modified. This preserves previous behavior when using a received object to modify a vlan. Add a capability NL_CAPABILITY_RTNL_LINK_VLAN_INGRESS_MAP_CLEAR to indicate the behavioral change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the io_alloc() implementation unconditionally allocated new memory, thus leaking memory if called more then once.
