This function is no longer needed as it is implemented in the PCEPlib, where it actually should be.

As far as I can see, the function in pceplib gives a description of the error and this function gives just a small identifier of the error. This is not very practical in the context of the debug information as it can get large. Am I missing something ?

Does this function still need the ctrl_state?

I don't want to remove it until it is actually implemented, ctrl_state is need for communicating with the controller, like for scheduling a timer for example.

Ok, then maybe we should move this functionality with the shorter descriptions to the pceplib, since it doesnt make sense to have it in multiple disparate places.
I believe there are other similar debugging functions that could probably also be moved to the pceplib, but this can be done separately.

I am fin with that, there is multiple functions in path_pcep_debug that could go there.

@bradyallenjohnson Do you consider this a blocker for merging this feature ?

I think this discussion got moved to the wrong file. For now, can you remove the duplicate error message code and call the pceplib function that returns the lengthier description. Then we can merge this patch. Today I can add a patch to pceplib that returns a shorter description.

After talking to Sebastien in private, we'll go ahead and merge this as-is. Later (today or tomorrow) we'll add this code to pceplib and remove it from pathd.

Due to the github issues, this got merged but somehow the PR got broken, closing it. |

… the neighbor status remains UP Test Scenario: RouterA and RouterB are in the same routing domain and have configured a P2P link. RouterA is configured with "is-type level-1" while RouterB is configured with "is-type level-1-2". They establish a level-1 UP neighborship. In this scenario, we expect that when RouterB's configuration is switched to "is-type level-2-only", the neighborship status on both RouterA and RouterB would be non-UP. However, RouterB still shows the neighbor as UP. Upon receiving a P2P Hello packet, the function "process_p2p_hello" is invoked. According to the ISO/IEC 10589 protocol specification, section 8.2.5.2 a) and tables 5 and 7, if the "iih->circ_type" of the neighbor's hello packet does not match one's own "circuit->is_type," we may choose to take no action. When establishing a neighborship for the first time, the neighbor's status can remain in the "Initializing" state. However, if the neighborship has already been established and one's own "circuit->is_type" changes, the neighbor's UP status cannot be reset. Therefore, when processing P2P Hello packets, we should be cognizant of changes in our own link adjacency type. Topotest has identified a core issue during testing.

(gdb) p pthread No symbol "pthread" in current context. (gdb) p thread $1 = (struct event *) 0x10000 When LAN links and P2P links share the` circuit->u` of a neighbor, if one link is no longer in use and the union is not cleared, the other link is unable to pass the non-empty check, resulting in accessing an invalid pointer. Unfortunately, for non-DIS devices in LAN links, `circuit->u.bc.run_dr_elect[x]` is essentially always 1, but in `isis_circuit_down()`,` circuit->u.bc.run_dr_elect[x] `will not be cleared because `circuit->u.bc.is_dr[x]` is always 0. Consequently, when switching to a P2P link, `isis_circuit_circ_type_set()` does not reset the link in a non-C_STATE_UP state, leading to subsequent accesses of `circuit->u.p2p.t_send_p2p_hello` resulting in a non-empty yet invalid address. I believe that in `isis_circuit_down()`, the LAN link should unconditionally clear `circuit->u.bc.run_dr_elect[x]`. Signed-off-by: zhou-run <zhou.run@h3c.com>
