batadv_v_ogm_metric_update(9)

📦 version 7.3.1, in nixpkgs unstable

💅 batadv_v_ogm_metric_update — the kernel API manual, but make it make sense

okay so bestie, we're in the batadv_v_ogm_metric_update(9) page today — yes that's the manual name, yes it's a mouthful, no we're not shortening it. This one lives in the Kernel API Manual and it's literally all about updating the route metric based on OGM. That's the whole vibe. 🦋

✨ SYNOPSIS ✨

int batadv_v_ogm_metric_update (struct batadv_priv *bat_priv , const
struct batadv_ogm2_packet *ogm2 , struct batadv_orig_node *orig_node ,
struct batadv_neigh_node *neigh_node , struct batadv_hard_iface
*if_incoming , struct batadv_hard_iface *if_outgoing );

six arguments, one int coming back at you. she's serving function signature realness, no cap. 👑

🎀 ARGUMENTS 🎀

  • bat_priv — the bat priv that's holding all the mesh interface information. the main character of the struct collection, fr.
  • ogm2 — the OGM2 structure. that's it, that's the description, it's very lowkey about itself.
  • orig_node — the Originator structure for which the OGM has been received. iykyk.
  • neigh_node — the neigh_node through which the OGM has been received. the middleman. the messenger. respect her.
  • if_incoming — the interface where this packet was received. where it showed up. where it ate. 🍓
  • if_outgoing — the interface for which the packet should be considered. not the same as incoming, bestie, don't mix them up 💀

🌈 RETURN 🌈

three possible moods:

  • 1 — if the OGM is new. fresh off the wire. iconic. ✨
  • 0 — if it is not new but valid. not new, still valid, still slaying in her own way 💅
  • <0 — on error, e.g. an old OGM. yeah, that's a no from her 😭

🌸 SEE ALSO 🌸

the kernel file is ./net/batman-adv/bat_v_ogm.c and honestly the whole friend group is here — every single one of these, no skipping:

twenty-four whole references. she keeps her circle close and her (9) suffixes closer 🫶

ngl this page is short but she's doing exactly what she needs to do. read the args, respect the args, move on. periodt. 💜

and that's the tea, bestie — this one came from ./net/batman-adv, dated October 2026, and it's signed off as batadv_v_ogm_metric_update(9). go forth and update those metrics 🧚‍♀️⭐
