* lib: add type casting for nla_for_each_nested macroPrzemyslaw Szczerbik2016-02-251-1/+1
| | | | | | | | | | | g++ is unable to compile code with nla_for_each_nested macro due to implicit type conversion from void* to nlattr*. This patch adds type casting for nla_for_each_nested macro to address this issue.

| * lib: update ce-mask to uint64_tDavid Ahern2016-02-1225-64/+99
|/ | | | | | | | | | | | | | | | | | | | lib/route/link.c already defines 32 attributes which fills the current uint32_t used for ce_mask. To accommodate more attributes the mask needs to be expanded. This patch updates the definition to uint64_t. The nl_object_diff API is maintained for ABI with existing users. A new nl_object_diff64 API is added for the expanded attribute list. The MSB of the 32-bit API is used to indicate if higher order attributes had a mismatch. (Suggested by Thomas). Note that LINK_ATTR_LINK_NETNSID changes. But since the attribute flags are not public API it shouldn't be a problem. http://lists.infradead.org/pipermail/libnl/2015-December/002078.html http://lists.infradead.org/pipermail/libnl/2015-December/002083.html Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: Thomas Haller <thaller@redhat.com>

| * lib: handle family-based parsing of IFLA_AF_SPEC attributeDavid Ahern2015-12-072-13/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The encoding of the IFLA_AF_SPEC attribute varies depending on the family used for the request (RTM_GETLINK) message. For AF_UNSPEC the encoding has another level of nesting for each address family with the type encoded first. i.e., af_spec = nla_nest_start(skb, IFLA_AF_SPEC) for each family: af = nla_nest_start(skb, af_ops->family) af_ops->fill_link_af(skb, dev, ext_filter_mask) nest_end nest_end This allows the parser to find the address family by looking at the first type. Whereas AF_BRIDGE encoding is just: af_spec = nla_nest_start(skb, IFLA_AF_SPEC) br_fill_ifvlaninfo{_compressed}(skb, vg) nest_end which means the parser can not use the attribute itself to know the family to which the attribute belongs.

* route/vlan: allow clearing vlan ingress mapThomas Haller2015-11-193-3/+25
| | | | | | | | | | | | | | | | | | | | | 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.
