* pimd: Cleanup S,GRPt prune handling on Mroute LossDonald Sharp2017-08-241-2/+1
| | | | | | | | | | | | | 1) Clean up display of S,GRPt prune state to be more meaningful 2) Upon receipt of a S,GRPt prune make sure we transition to the correct state 3) Upon loss of a S,GRPt prune make sure we transition to the correct state as well as immediately send a *,G join upstream to propagate the loss of the prune. 4) Removal of a weird S,G state being installed upon loss of a S,G RPt prune.

* pimd: Convert to using a RB tree for the pim_ifp ifchannel_listDonald Sharp2017-08-021-2/+8
| | | | | | | | This patch does two things: 1) Converts the pim_ifp->ifchannel_list to a pim_ifp->ifchannel_rb 2) Removes the hashing to use the RB RB_FIND instead. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* pimd: Fix code to not send joins when SGRPT Prune is receivedDonald Sharp2017-07-241-1/+2
| | | | | | | | | | | | | | | When we receive a SGRPT Prune we were switching the upstream to JOINED and immediately sending a join. This was not the right thing to do. This was happening because we were making decisions about the new ifchannel before it was fully formed. Rework ifchannel startup to provide enough information to the pim upstream data structure to make the right decisions Ticket: CM-16425 Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* | *: make consistent & update GPLv2 file headersDavid Lamparter2017-05-151-18/+17
|/ | | | | | | | | | | 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 Shah2017-04-251-1/+1
| | | | | | | | | | | | | | | | 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. Testing Done: 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>
* pimd: Add display of SGRpt state for ifchannelDonald Sharp2017-03-171-1/+1

* pimd: Make ifchannel lookup a hash lookupDonald Sharp2017-02-241-0/+3
| | | | | | | | | When we are at scale, it is possible that we have a very large number of ifchannels per interface. So make lookup for that situation to be a hash lookup. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* pimd: Narrow inheritance search down to interface we are interested in.Donald Sharp2017-02-241-0/+1

* pimd: Use correct flag to add an oifDonald Sharp2017-01-301-2/+2
| | | | | | | | | | | | When we are creating the igmp ifchannel we were creating it with both a P and a I flag. This was causing it to not be cleaned up properly when the interface was shut down. Subsuquently when the interface came back up we would attempt to add it back in but it would fail. Ticket: CM-14586 Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

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>
