When withdrawing addpaths, adj_lookup was called to find the path that needed to be withdrawn. It would lookup in the RB tree based on subgroup pointer alone, often find the path with the wrong addpath ID, and return null. Only the path highest in the tree sent to the subgroup could be found, thus withdrawn. Adding the addpath ID to the sort criteria for the RB tree allows us to simplify the logic for adj_lookup, and address this problem. We are able to remove the logic around non-addpath subgroups because the addpath ID is consistently 0 for non-addpath adj_outs, so special logic to skip matching the addpath ID isn't required. (As a side note, addpath will also never use ID 0, so there won't be any ambiguity when looking at the structure content.) Signed-off-by: Mitchell Skiba <mskiba@amazon.com> |
