* pimd: fixup (S,G,rpt) prune to conform to the RFCAnuradha Karuppiah2019-11-151-27/+24
| | | | | | | | | Deviations - 1. Avoid using SPTbit setting. Replace that with Use_Spt macro. 2. If S is supposed to be forwarded along the RPT but has an empty OIL prune it. Signed-off-by: Anuradha Karuppiah <anuradhak@cumulusnetworks.com>

* pimd: RPT Prunes do not need to be figured for a *,G PruneDonald Sharp2018-07-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Packet sending in PIM is a two step process. 1) Gather data size of next G to be packed into a packet. 2) Write data After 1 we need to ensure that the next G to pack will actually fit in a packet. If it does not send what we've currently written and start a new packet to send. Because this was a 2 step process it is important to be consistent in what you think you have packed -vs- what you think you should. PIM has a bug where we were considering S,G RPT Prunes for a *,G even when the *,G was being pruned. This lead to a situation where we were figuring a write size of more data then what we actually wrote into a packet. This would leave a 8 byte whole of 0's in the packet due to the way we moved pointers around. Fix the code so that we do not attempt to consider S,G rpt prunes for a *,G prune when figuring out how much we should write in step 1.

| | | | | | | | | | | The FSF's address changed, and we had a mixture of comment styles for the GPL file header. (The style with * at the beginning won out with 580 to 141 in existing files.) Note: I've intentionally left intact other "variations" of the copyright header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

* pimd: Fix WG/SGRpt & WG J/P processingChirag Shah2017-05-071-1/+3
| | | | | | | | | | | | | | | | | | | | During processing of Join/Prune, for a S,G entry, current state is SGRpt, when only *,G is received, need to clear SGRpt and add/inherit the *,G OIF to S,G so it can forward traffic to downstream where *,G is received. Upon receiving SGRpt prune remove the inherited *,G OIF. From, downstream router received *,G Prune along with SGRpt prune. Avoid sending *,G and SGRpt Prune together. Reset upstream_del reset ifchannel to NULL. Testing Done: Run failed smoke test of sending data packets, trigger SPT switchover, *,G path received SGRpt later data traffic stopped S,G ages out from LHR, sends only *,G join to upstream, verified S,G entry inherit the OIF. Upon receiving SGRpt deletes inherited oif and retains in SGRpt state. Signed-off-by: Chirag Shah <chirag@cumulusnetworks.com>

This is assured already because buffer sizes are checked for minimum lengths for the entire packet ahead of time. So we are double checking.

| | | | | | | | | | | | | | Ticket: CM-12041 Reviewed By: sharpd, CCR-5556 Testing Done: Tested on Local setup generating PIM Register (Data/Null) and processing both Tx/Rx with correct checksum. Provided quagga debian to submitter and checksum cases passed on submitter setup. 1. PIM Register msg checksum only accounts for 8 bytes (4 bytes for PIM header and next 4 byetes before data payload). In PIM header checksum calculation checked PIM packet type (in this case REGISTER type) then only pass 8 bytes as length rather than full packet length. 2. PIM Register Rx path also handled with 8 byte and full pim lenth checksum. Signed-off-by: Chirag Shah <chirag@cumulusnetworks.com>

* | pim-anycast-rp: Add limited support for secondary addresses.anuradhak2016-12-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Anycast requires that the lo interface be associated with multiple addresses. One is the anycast IP address (which is the same on all RPs participating in RP redundancy) and the second is the unique IP address that will be used as the router id by routing protocols. To accomodate that we maintain a list of secondary addresses per-pim iface and allow any of them to be the RP address. This lets the I_am_RP macro succeed on anycast RPs. Note that the support is limited i.e. we don't actually advertise a secondary list to the neighbors. This is assuming the anycast IP will never be used as a router id i.e. will never be an RPF neighbor.

Welcome pimd to the Quagga daemon zoo! This is a merge of commit 77ae369 ("pimd: Log ifindex found for an interface when zebra lib reports a new connected address."), with the intermediate "reconnect" changes removed (c9adf00...d274381). d274381 is replaced with b162ab7, which includes some changes. In addition, 4 reconnect-related changes and 1 cosmetic one have been bumped out. The rebase command used to produce the branch that is merged here is: git rebase --onto b162ab7 c9adf00 77ae369 Note that 3 patches had their author rewritten from "Anonymous SR#108542 <>" (which is not a valid git author ID) to: "Savannah SR#108542 <nbahr@atcorp.com>" (which is the e-mail address listed in the associated Savannah ticket) Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
