* If no reply to a computation request is received after a configurable amount of time, the PCC will try again up to a total of 4 requests. IF all of them timeout, the candidate will be delgated with an empty segment list. the timeout can be configured with the client command `timer pcep-request`. * Fix an issue with interpreting SR sub-objects without the MPLS flag set.

The issue arises because rtrlib initiates its own separate pthread in which it runs the hook, which does not establish an FRR RCU context. Consequently, this leads to failures in the logging mechanism that relies on RCU. Initialize a new FRR pthread context from the rtrlib pthread with a valid RCU context to allow logging from the rpki_create_socket() and dependent functions.

… 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>
