The idea is pretty similar to recently introduced cgroup sysctl hooks, but implementation is simpler (no need to convert to/from strings). What this can be applied to: * move business logic of what tos/priority/etc can be set by containers (either pass or reject) * handle existing options (or introduce new ones) differently by propagating some information in cgroup/socket local storage Compared to a simple syscall/{g,s}etsockopt tracepoint, those hooks are context aware. Meaning, they can access underlying socket and use cgroup and socket local storage. v9: * allow overwriting setsocktop arguments (Alexei Starovoitov) (see individual changes for more changelog details) ==================== Signed-off-by: Alexei Starovoitov --- 2ec1899e99b4959bd2a46fd3993220e4f1a5397f
