* zebra: start the netns notification mechanism after ns initialisationPhilippe Guibert2019-01-091-1/+5
| | | | | | | | | | | | | when zebra is run, by using vrf netns backend mode, then the parser detector of netns is run before forcing the default vrf to a possible value. In that case, there is a possibility that the forced '-o' option will create a second vrf with same name, whereas this option should be there to uniquely have a default vrf with a value. To make things consistent, the forced value will be priorised. Then, the notifier will attempt to create vrf contexts. The expectation is that the creation will fail, due to an already present vrf with same name. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>

* zebra: avoid initialising more than one the l3vni hash structurePhilippe Guibert2018-12-171-3/+0
| | | | | | | | | the l3vni structure is allocated only once, since that structure is only used for default netns. For that, move the initialisation part is moved to a proper place, where there is no risk of attempting to initialise it more than once, even when vrf backend is netns.

* zebra: separate netlink socket for dataplaneMark Stapp2018-11-211-5/+34
| | | | | | | | | | Use a separate netlink socket for the dataplane's updates, to avoid races between the dataplane pthread and the zebra main pthread. Revise zebra shutdown so that the dataplane netlink socket is cleaned-up later, after all shutdown-time dataplane work has been done. Signed-off-by: Mark Stapp <mjs@voltanet.io>

* zebra: Start breakup of zns into zrouter and znsDonald Sharp2018-10-241-123/+0
| | | | | | | | | | | | | | | | | | | | | | The `struct zebra_ns` data structure is being used for both router information as well as support for the vrf backend( as appropriate ). This is a confusing state. Start the movement of `struct zebra_ns` into 2 things `struct zebra_router` and `struct zebra_ns`. In this new regime `struct zebra_router` is purely for handling data about the router. It has no knowledge of the underlying representation of the Data Plane. `struct zebra_ns` becomes a linux specific bit of code that allows us to handle the vrf backend and is allowed to have knowledge about underlying data plane constructs. When someone implements a *bsd backend the zebra_vrf data structure will need to be abstracted to take advantage of this instead of relying on zebra_ns.

* zebra: add IPTABLE_ADD and IPTABLE_DEL commands in zapiPhilippe Guibert2018-04-161-0/+9
| | | | | | | | | | | Those messages permit a remote daemon to configure an iptable entry. A structure is defined that maps to an iptable entry. More specifically, this structure proposes to associate fwmark, and a table ID. Adding to the configuration, the initialisation of iptables hash list is done into zebra netnamespace. Also a hook for notifying the sender that the iptables has been correctly set is done. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
* zebra: handle entry pointfs for ipset creation/destructionPhilippe Guibert2018-04-161-0/+14

* zebra: add an indirection table for ns_idPhilippe Guibert2018-04-131-3/+4
| | | | | | | | | | This list "table" is created in the case the netns backend for VRF is used. This contains the mapping between the NSID value read from the 'ip netns list' and the ns id external used to create the VRF value from vrf context. This mapping is necessary in order to reserve default 0 value for vrf_default. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
* zebra: add the handling of table ids from remote daemonsPhilippe Guibert2018-03-291-0/+6

* zebra: Read in on startup arbitrary tablesDonald Sharp2018-03-161-0/+11
| | | | | | | | | | | | | | | When we receive an arbitrary table over the netlink bus save it for later perusal and sweep any routes that we may have created from an earlier run. The current redistribute code is limited to ZEBRA_KERNEL_TABLE_MAX. I left this alone for the moment because I believe it needs to be converted to a RB tree instead of a flat array. Which is more work for the future. Additionally this proposed change might necessitate some cli changes or rethinks. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* zebra: adapt the vrf and logical router initialisationPhilippe Guibert2018-02-271-3/+22
| | | | | | | | The zebra daemon introduces the logical router initialisation. Because right now, the usage of logical router and vrf NETNS is exclusive, then the logical router and VRF are initialised accordingly. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
* zebra: upon startup, a NSID is assigned to default netnsPhilippe Guibert2018-02-271-1/+11
| | | | | | | | | | | | | | | | | | 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.

* zebra: collect and get netnamespaces informationPhilippe Guibert2018-02-271-0/+3
| | | | | | | | | | | | | | 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).

* zebra: handle the zns init/destroyPhilippe Guibert2018-02-271-2/+15
| | | | | | | | 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>
* zebra: add the registration mechanism for netnsPhilippe Guibert2018-02-271-1/+62
| | | | | | | | | | | 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>
* zebra: copy logical-router-command under vrf subnodePhilippe Guibert2018-02-271-0/+8
| | | | | | | | | | | | | | | | | | | 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.

* zebra: Move zvrf->other_tables into znsDonald Sharp2018-02-231-0/+69
| | | | | | | | | | | | The other_tables data structure does not belong to a vrf. It belongs to the zns. This is because each vrf does not need to have copies of each of other_tables. Additionally move the array into a RB_TREE. This will allow us to sort quickly and easily expand the number of tables we can support to beyond the ZEBRA_KERNEL_TABLE_MAX define.

* *: Handle VRF configuration when VRF gets inactivated and activatedvivek2018-01-241-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A VRF is active only when the corresponding VRF device is present in the kernel. However, when the kernel VRF device is removed, the VRF container in FRR should go away only if there is no user configuration for it. Otherwise, when the VRF device is created again so that the VRF becomes active, FRR cannot take the correct actions. Example configuration for the VRF includes static routes and EVPN L3 VNI. Note that a VRF is currently considered to be "configured" as soon as the operator has issued the "vrf <name>" command in FRR. Such a configured VRF is not deleted upon VRF device removal, it is only made inactive. A VRF that is "configured" can be deleted only upon operator action and only if the VRF has been deactivated i.e., the VRF device removed from the kernel. This is an existing restriction. To implement this change, the VRF disable and delete actions have been modified.
