Before this patch, and upon the reception of the\nRM_ADDR, the other peer will then try to decrement this\nadd_addr_accepted. That's not correct because the attached subflows have\nnot been created upon the reception of an ADD_ADDR.\n\nA way to solve that is to decrement the counter only if the attached\nsubflow was an MP_JOIN to a remote id that was not 0, and initiated by\nthe host receiving the RM_ADDR.", "affected": [ { "package": { "ecosystem": "Raspberry Pi OS:12", "name": "linux" }, "versions": [
