Re: [PATCH net] net/sched: act_gate: budget the per-entry list in get_fill_size

Hello:

This patch was applied to netdev/net.git (main)

tcf_gate_get_fill_size returns only the TCA_GATE_PARMS size, but
tcf_gate_dump also emits three 64-bit timestamps, the clock id, flags,
priority and the variable-length TCA_GATE_ENTRY_LIST nest. The per-entry
nest is unbounded: parse_gate_list places no cap on the number of
sched-entries, so a gate with many entries can push the real dump well
past the skb that tca_get_fill allocates from this size.
