💅 batadv_iv_ogm_update_seqnos(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're being fancy today 🎀 — and today's main character is batadv_iv_ogm_update_seqnos. She's a whole vibe.

✨ NAME ✨

batadv_iv_ogm_update_seqnos — process a batman packet for all interfaces, adjust the sequence number and find out whether it is a duplicate 🦋

like, she takes the packet, she runs it past every interface, she tweaks that sequence number, and then she's the one who goes "hmm… have i seen you before?" 💅

🌸 SYNOPSIS 🌸

enum batadv_dup_status batadv_iv_ogm_update_seqnos (const struct ethhdr
*ethhdr , const struct batadv_ogm_packet *batadv_ogm_packet , const
struct batadv_hard_iface *if_incoming , struct batadv_hard_iface
*if_outgoing );

not me dropping the entire signature on you, but yes, that's her in all her glory — copy it exactly, no freestyling 🙈

💖 ARGUMENTS 💖

  • ethhdr — the ethernet header of the packet. yep, the preamble situation 🎀
  • batadv_ogm_packet — the OGM packet we're actually considering here. the one under the microscope 🔍
  • if_incoming — the interface on which the OGM packet was received. where she came in at 👋
  • if_outgoing — the interface for which the retransmission should be considered. where she might be headed next 🛫

⭐ RETURN ⭐

she gives you back a duplicate status, as enum batadv_dup_status 👑

like — that's literally the entire answer. is it a dupe or not. iconic behaviour, no notes.
