Removing or expiring a proxy path\ntherefore returns a slot that was never charged.\n\nmesh_path_add() uses the same counter to enforce MESH_MAX_MPATHS, so once\nit falls below the number of installed paths the limit no longer holds.\n\nReserve the shared quota before allocating a proxy path and release it on\nevery unsuccessful addition. Mesh and proxy paths now share one\n1024-entry budget, so mpp_path_add() can return -ENOSPC at that limit.","state":0,"publishedAt":"2026-10-18T15:46:35.52+00:00","modifiedAt":"2026-10-21T12:55:53.953+00:00","affected":[{"ecosystem":"Vendor
