But SO_TXTIME was later added, which can send skbs with timestamps against other clocks. It is now possible to detect these through skb tstamp_type. Make FQ robust by converting these timestamps for use in FQ (patch 2). This also requires testing against out-of-bounds values. Prefer to do this at the source, when parsing SCM_TXTIME (patch 1). But, tests in the hot path are still needed, to handle BPF sources. Extend the so_txtime selftest to handle this new case (patch 3). v1: https://lore.kernel.org/20260603190243.2789335-1-willemdebruijn.kernel@gmail.com ==================== Link: https://patch.msgid.link/20260604194221.3319080-1-willemdebruijn.kernel@gmail.com Signed-off-by: Jakub Kicinski --- 1e127c94fa11cd55c8495c4b13bb255094683b4c
