* route/addr: fix handling peer addresses for IPv4 addressesThomas Haller2016-06-291-19/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For IPv4, a "normal" route has IFA_LOCAL and IFA_ADDRESS set to the same destination. An address with a explicit peer, has them differing. A peer of 0.0.0.0 is also valid and must be treated different from a normal address. unshare -n ip link add T type dummy ip link set T up ip addr add 192.168.5.10 peer 192.168.5.10/24 dev T ip addr add 192.168.5.10/24 dev T #RTNETLINK answers: File exists ip addr add 192.168.5.10 peer 192.168.6.10/24 dev T ip addr add 192.168.5.10 peer 0.0.0.0/24 dev T Previously, that would give: nl-addr-list #192.168.5.10/24 inet dev T scope global <permanent> #192.168.5.10 peer 192.168.6.10/24 inet dev T scope global <permanent> #192.168.5.10/24 inet dev T scope global <permanent> With this change, we properly get: nl-addr-list #192.168.5.10/24 inet dev T scope global <permanent> #192.168.5.10/24 peer 192.168.6.10 inet dev T scope global <permanent> #192.168.5.10/24 peer 0.0.0.0 inet dev T scope global <permanent> http://lists.infradead.org/pipermail/libnl/2016-June/002157.html Signed-off-by: Thomas Haller <thaller@redhat.com>
* route/addr: fix ID comparison for AF_INET and AF_INET6 addressesThomas Haller2016-06-291-1/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For AF_INET/IPv4 addresses, the ID equality comparison must include the net-part of the peer address: unshare -n ip link add T type dummy ip link set T up ip addr add 192.168.5.10/24 dev T ip addr add 192.168.5.10 peer 192.168.6.1/24 dev T ip addr add 192.168.5.10 peer 192.168.7.1/24 dev T ip addr add 192.168.5.10 peer 192.168.7.2/24 dev T # RTNETLINK answers: File exists ip addr change 192.168.5.10 peer 192.168.7.2/24 dev T ip addr show | grep 192.168.7. # inet 192.168.5.10 peer 192.168.7.1/24 scope global T For AF_INET6/IPv6 addresses, the prefix length of the address is not part of the ID: unshare -n ip link add T type dummy ip link set T up ip addr add 192.168.7.10/24 dev T ip addr add 192.168.7.10/23 dev T ip addr add 1:2:3:4:5::1/64 dev T ip addr add 1:2:3:4:5::1/63 dev T # RTNETLINK answers: File exists ip addr change 1:2:3:4:5::1/63 dev T ip addr show | grep 1:2:3:4:5::1 # inet6 1:2:3:4:5::1/64 scope global *sigh* http://lists.infradead.org/pipermail/libnl/2016-June/002158.html Signed-off-by: Thomas Haller <thaller@redhat.com>

* link: support RTEXT_FILTER_VFJef Oliver2016-06-241-2/+16
| | | | | | | | | | | | | | | This patch adds RTEXT_FILTER_VF mask support for SRIOV VFs. Since SRIOV VFs don't have a defined address family (ie bridge), there are no new address family specific operations defined.

* neigh: add function to look up neighbour (fdb) by ifindex, mac and vlanJonas Johansson2016-05-291-0/+26
| | | | | | | | | | | | | | | | | The rtnl_neigh_get() function can not be used to look up a fdb entry in the neigh cache. This is due to that the function searches among destination addresses (NDA_DST) and not among link layer addresses (NDA_LLADDR), which is used by fdb entries. A fdb entry can also exist in several vlans, so a vlan id parameter is also needed to find a unique entry. This commit adds a function, rtnl_neigh_get_by_vlan() which searches the neigh cache for a specific neighbour (fdb) entry by interface index, link layer address and vlan id.

* 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>

* lib: update ce-mask to uint64_tDavid Ahern2016-02-127-22/+24
| | | | | | | | | | | | | | | | | | | | 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 Ahern2015-12-071-13/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Haller2015-11-191-2/+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.

This way when adding new modes, rtnl_link_ipvlan_set_mode() does not need to be changed. If the user passes an invalid value and sends a message to the kernel, it will be rejected there. http://lists.infradead.org/pipermail/libnl/2015-June/001902.html Fixes: 7de5be85bf9aa3eb9f022e4813226135e89adec2 Signed-off-by: Thomas Haller <thaller@redhat.com>
