zebra, bgp: Support type-5 routes with asymmetric routing
The netns backend is chosen by VRF if a runtime flag named vrfwnetns is selected when running zebra. In the case the NETNS backend is chosen, in some case the VRFID value is being assigned the value of the NSID. Within the perimeter of that work, this is why the vrf_lookup_by_table function is extended with a new parameter. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
a vty command is added: in addition to this command ( kept for future usage): - [no] logical-router-id <ID> netns <NETNSNAME> a new command is being placed under vrf subnode - vrf <NAME> [no] netns <NETNSNAME> exit This command permits to map a VRF with a Netnamespace. The commit only handles the relationship between vrf and ns structures. It adds 2 attributes to vrf structure: - one defines the kind of vrf ( mapped under netns or vrf from kernel) - the other is the opaque pointer to ns The show running-config is handled by zebra daemon.

Using the vrf backend kind, the vty command that configured netns under vty will not be installed if the vrf backend is vrf lite Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
Upon following calls: interface poll, address poll, route poll, and ICMPv6 handling, each new Namespace is being parsed. For that, the socket operations need to switch from one NS to one other, to get the necessary information. As of now, there is a crash when dumping interfaces, through show running-config.

This commit is also a fix that avoids a VRF to be attached to the wrong namespace context, at creation time. Because the VRF, at creation time does not know yet the namespace where it will get its information. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
In addition to have the possibility to create from vty vrf based on a netns backend, the API will be made accessible from external, especially for zebra that will handle the netns discovery part. This commit is externalising following functions: - netns_pathname - ns_handler_create - vrf_handler_create Also, the VRF initialisation case when under NETNS backend is changed, since the NS identifier may not be known at the configuration time,but may be known later, under discovery process. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
If vrf backend is netns, then the zebra will create its own zebra_ns context for each new netns discovered. As consequence, a routing table, and other contexts will be created for each new namespace discovered. When it is enabled, a populate process will be done, consisting in learning new interfaces and routes, and addresses from other NETNS. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
The zebra netnamespace contexts are initialised, based on the callback coming from the NS. Reversely, the list of ns is parsed to disable the ns contexts. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
Show vrf command displays information on the vrf, if it is related to vrf kernel or if it is related to netns. When a vrf from kernel is detected, before creating a new vrf, a check is done against an already present vrf, and if that vrf is not a vrf mapped with a netns. If that is that case, then the creation is rejected. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
The addition of the name of the netns in the vrf message introduces also a limitation when the size of the netns is bigger than 15 bytes. Then the netns are ignored by the library. In addition to this, some sanity checks have been introduced. some functions to create the netns from a call not coming from the vty is being added with traces. Also, the ns vty function is reentrant, if the context is already created. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com> Signed-off-by: Renato Westphal <renato@opensourcerouting.org>
Two apis are provided so that the switch from one netns to an other one is taken care. Also an other API to know if the VRF has a NETNS backend or a VRF Lite backend. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
A NS identifier is collected by netlink. This identifier is a 32 bit identifier that is either generated by the kernel (if not set) or manually set by a set netlink command. The commit here is getting the NSID from the newly created NS. If the linux option to create or get a new NSID from the kernel does not exist, then the NSID is locally genrated. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
upon zebra initialisation, and upon further netnamespace creation, the the netnamespaces are created and a vrf associated to the netnamespace is created. By convention, the name of the netns will be the same as the VRF. Add a stub routine that returns a fake ns identifier, in case netlink ( linux machines) is not available. Also, upon each newly discovered NETNS, a NSID id being generated, either by relying on kernel NSID feature, or by generating locally the NSID ( see previous commit for more information). Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
when the netns backend is selected for VRF, the default VRF is being assigned a NSID. This avoids the need to handle the case where if the incoming NSID was 0 for a non default VRF, then a specific handling had to be done to keep 0 value for default VRF. In most cases, as the first NETNS to get a NSID will be the default VRF, most probably the default VRF will be assigned to 0, while the other ones will have their value incremented. On some cases, where the NSID is already assigned for NETNS, including default VRF, then the default VRF value will be the one derived from the NSID of default VRF, thus keeping consistency between VRF IDs and NETNS IDs. Default NS is attempted to be created. Actually, some VMs may have the netns feature, but the NS initialisation fails because that folder is not present.

this is a static analysis performed by c-lang scan-build tool that demonstrated this issue. This commit is handling the fix. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
For supporting vrf based on namespaces, it is possible that an interface with the same index is present. This is the case for loopback interfaces. For that, for each query, if the interface is not found , matching the vrf identifier, then a new interface is created, when the backens for VRF is NETNS. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
the vrf identifier in the ospf_vrf_enable routine is never read, then does not need to be initialised. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
The assert appears in zebra_mpls.c when checking default zebra_vrf. It appears that when the mpls entries are flushed, it gets the default vrf which is already flushed by vrf_terminate() function. In order to avoid that assert to trigger a crash, the mpls flush is called before vrf termination. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
The vrf_sockunion_socket() wraps sockunion_socket() with vrf_id as additional parameter. The creation of socket forces the user to transparently move to new NETNS for doing the operation. The vrf_getaddr_info() wraps getaddr_info() with vrf_id as additional parameter. That API relies on the underlying system. Then there may be need to switch to an other netns in that case too. Also, the vrf_socket() implementation is simplified. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
The change contained in this commit does the following: - discovery of vrf id from zebra daemon, and adaptation of bgp contexts with BGP. The list of network addresses contain a reference to the bgp context supporting the vrf. The bgp context contains a vrf pointer that gives information about the netns path in case the vrf is a netns path. Only some contexts are impacted, namely socket creation, and retrieval of local IP settings. ( this requires vrf identifier). Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
Upon creation of BGP instances, server socket may or may not be created. In the case of VRF instances, if the VRF backend relies on NETNS, then a new server socket will be created for each BGP VRF instance. If the VRF backend relies on VRF LITE, then only one server socket will be enough. Moreover, At startup, with BGP VRF configuration, a server socket may not be created if VRF is not the default one or VRF is not recognized yet. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
Upon starting a BGP VRF instance, the server socket is not created, because the VRF ID is not known, and then underlying VRF backend is not ready yet. Because of that, the peer connection attempt will not be started before. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>

This is an implementation of PBR for FRR.
This implemenation uses a combination of rules and
tables to determine how packets will flow.
PBR introduces a new concept of 'nexthop-groups' to
specify a group of nexthops that will be used for
ecmp. Nexthop-groups are specified on the cli via:
nexthop-group DONNA
nexthop 192.168.208.1
nexthop 192.168.209.1
nexthop 192.168.210.1
!
PBR sees the nexthop-group and installs these as a default
route with these nexthops starting at table 10000
robot# show pbr nexthop-groups
Nexthop-Group: DONNA Table: 10001 Valid: 1 Installed: 1
Valid: 1 nexthop 192.168.209.1
Valid: 1 nexthop 192.168.210.1
Valid: 1 nexthop 192.168.208.1
I have also introduced the ability to specify a table
in a 'show ip route table XXX' to see the specified tables.
robot# show ip route table 10001
Codes: K - kernel route, C - connected, S - static, R - RIP,
O - OSPF, I - IS-IS, B - BGP, P - PIM, E - EIGRP, N - NHRP,
T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP,
F - PBR,
> - selected route, * - FIB route
F>* 0.0.0.0/0 [0/0] via 192.168.208.1, enp0s8, 00:14:25
* via 192.168.209.1, enp0s9, 00:14:25
* via 192.168.210.1, enp0s10, 00:14:25
PBR tracks PBR-MAPS via the pbr-map command:
!
pbr-map EVA seq 10
match src-ip 4.3.4.0/24
set nexthop-group DONNA
!
pbr-map EVA seq 20
match dst-ip 4.3.5.0/24
set nexthop-group DONNA
!
pbr-maps can have 'match src-ip <prefix>' and 'match dst-ip <prefix>'
to affect decisions about incoming packets. Additionally if you
only have one nexthop to use for a pbr-map you do not need
to setup a nexthop-group and can specify 'set nexthop XXXX'.
To apply the pbr-map to an incoming interface you do this:
interface enp0s10
pbr-policy EVA
!
When a pbr-map is applied to interfaces it can be installed
into the kernel as a rule:
[sharpd@robot frr1]$ ip rule show
0: from all lookup local
309: from 4.3.4.0/24 iif enp0s10 lookup 10001
319: from all to 4.3.5.0/24 iif enp0s10 lookup 10001
1000: from all lookup [l3mdev-table]
32766: from all lookup main
32767: from all lookup default
[sharpd@robot frr1]$ ip route show table 10001
default proto pbr metric 20
nexthop via 192.168.208.1 dev enp0s8 weight 1
nexthop via 192.168.209.1 dev enp0s9 weight 1
nexthop via 192.168.210.1 dev enp0s10 weight 1
The linux kernel now will use the rules and tables to properly
apply these policies.
