Signed-off-by: ryndia <dindyalsarvesh@gmail.com>

This commit ensures proper cleanup by deleting the gm_join_list when a PIM interface is deleted. The gm_join_list was previously not being freed, causing a memory leak. The ASan leak log for reference: ``` *********************************************************************************** Address Sanitizer Error detected in

… 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>

When using "vtysh -f", the northbound compatible configuration is committed together whereas, in interactive mode, it committed line by line. In the first situation, in validation state nb_running_get_entry() fails because the area not yet in running. Do not use nb_running_get_entry() northbound validation state.

… 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 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>

… 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>
