STRUCT CAN_SKB_EXT(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual page for struct can_skb_ext(9) — it's literally the struct can_skb_ext page, aka skb extensions for CAN specific content, fr fr. it's giving very specific little struct energy and honestly? obsession 💅.

🦋 SYNOPSIS 🦋

here's the whole cutie in C-struct form — keep it exact, no edits, periodt:

       struct can_skb_ext {
           int can_iif;
           u16 can_framelen;
           u8 can_gw_hops;
           u8 can_ext_flags;
           u32 can_skb_uid;
        };

🌸 Members 🌸

• can_iif — the ifindex of the first interface the CAN frame appeared on. lowkey important, iykyk.
• can_framelen — cached echo CAN frame length for bql. yes bestie, cached, that's the whole vibe ✨.
• can_gw_hops — the can-gw CAN frame time-to-live counter. hops but make it CAN-gw 🐇.
• can_ext_flags — CAN skb extensions flags. flags! we love a flag moment 🎀.
• can_skb_uid — CAN skb UID for raw_rcv and isotp echo handling. no cap, it's right there 🫶.

🎀 SEE ALSO 🎀

• Kernel file ./include/net/can.h — go read it bestie, it's literally the reference 💖.

mwah 💋 this little page came from ./include/net, dated October 2026, and it's the struct can_skb_ext(9) manual page. byeee 🫶✨
