2019-11-13pimd : Add support for MLAG Register & Un-registerSatheesh Kumar K
when ever a FRR Client wants to send any data to another node using MLAG Channel, uses below mechanisam. 1. sends a MLAG Registration to zebra with interested messages that it is intended to receive from peer. 2. In response to this request, Zebra opens communication channel with MLAG. and also in Rx. diretion zebra forwards only those messages which client shown interest during registration 3. when client is no-longer interested in communicating with MLAG, client posts De-register to Zebra 4. if this is the last client which is interested for MLAG Communication, zebra closes the channel. why PIM Needs MLAG Communication ================================ 1. In general on LAN Networks elecetd DR will send the Join towards Multicast RP in case of a LHR and Register in case of FHR. 2. But in case DR Goes down, traffic will be re-converged only after the New DR is elected, but this can take time based on Hold Timer to detect the DR down. 3. this can be optimised by using MLAG Mecganisam. 4. and also Traffic can be forwarded more efficiently by knowing the cost towards RP using MLAG Signed-off-by: Satheesh Kumar K <sathk@cumulusnetworks.com>

2019-04-21pim: fix order of vxlan mroutes cleanup when pimd is shutdownAnuradha Karuppiah
1. vxlan instance cleanup needs to be done before the upstream entries are force-flushed. 2. also vxlan callbacks need to be ignored post instance-cleanup. Signed-off-by: Anuradha Karuppiah <anuradhak@cumulusnetworks.com>
2019-04-20pimd: initial infrastructure to maintain VxLAN SG databaseAnuradha Karuppiah
These entries will be used over the subsequent commits for 1. vxlan-tunnel-termination handling - setup MDT to rx VxLAN encapsulated BUM traffic. 2. vxlan-tunnel-origination handling - register local-vtep-ip as a multicast source. Signed-off-by: Anuradha Karuppiah <anuradhak@cumulusnetworks.com>
2019-01-04pimd: Remove pimgDonald Sharp
The pimg data structure is only used in one spot to send the default vrf id to zebra upon startup. Add the default vrf id to the struct pim_router data structure and remove the pimg pointer. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
2019-01-04pimd: Create a `struct pim_router` and move thread master into itDonald Sharp
Create a `struct pim_router` and move the thread master into it. Future commits will further move global varaibles into the pim_router structure. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
2018-10-23vtysh: fix exit-vrf printingQuentin Young
Resolves issue with exit-vrf being placed at the end of zebra's portion of a vrf block, but before other daemons' portions of the same config block. Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>

Signed-off-by: David Lamparter <equinox@diac24.net>
2018-09-24pimd: Fix several address sanitizer issuesDonald Sharp
This commit fixes two issues during pim shutdown. 1) The rp_info structure was being freed before the outgoing notifications that depended on it's information was sent out as part of shutdown. 2) The pim->upstream_list shutdown involved iterating over the list via ALL_LIST_ELEMENTS. This typically is enough but pim will auto delete child nodes as well as itself when it goes away and they depend on it. As such the node and nnode could possibly already have been freed. So change the way we look at all the data in the upstream_list Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
2018-08-28*: add a vrf update hook to be informed of the vrf namePhilippe Guibert
The Vrf aliases can be known with a specific hook. That hook will then, from zebra propagate the information to the relevant zapi clients. The registration hook function is the same for all daemons. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>

2018-06-07pimd: Fix ecmp_enable and ecmp_rebalance_enableDonald Sharp

2018-05-11pimd: Clean up rpf_hash *after* upstream cleanupDonald Sharp

2018-03-17pimd: Move some data tracking variables per VRFDonald Sharp
There were a few more global variables that needed to be per vrf. So move them over. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
2018-03-13lib: privileges are granted to vty netns commandPhilippe Guibert

2017-10-05*: Convert list_delete(struct list *) to ** to allow nullingDonald Sharp
Convert the list_delete(struct list *) function to use struct list **. This is to allow the list pointer to be nulled. I keep running into uses of this list_delete function where we forget to set the returned pointer to NULL and attempt to use it and then experience a crash, usually after the developer has long since left the building. Let's make the api explicit in it setting the list pointer to null. Cynical Prediction: This code will expose a attempt to use the NULL'ed list pointer in some obscure bit of code.

2017-09-15*: use clang's 'ForEachMacros' format style optionRenato Westphal
