batadv_v_ogm_forward(9)

📦 version 7.3.1, in nixpkgs unstable

💖 batadv_v_ogm_forward(9) 💖

okay so bestie, we're in the Kernel API Manual today and the star of the show is batadv_v_ogm_forward(9) — yes that's the whole title, yes it's a lot, no we're not scared of it 🫶

✨ NAME ✨

batadv_v_ogm_forward — the function that checks all the conditions and then forwards an OGM out the given outgoing interface 💅

🌸 SYNOPSIS 🌸

void batadv_v_ogm_forward (struct batadv_priv *bat_priv , const struct
batadv_ogm2_packet *ogm_received , struct batadv_orig_node *orig_node ,
struct batadv_neigh_node *neigh_node , struct batadv_hard_iface
*if_incoming , struct batadv_hard_iface *if_outgoing );

like, it returns void and takes six whole arguments. she's high maintenance and she's worth it 👑

🎀 ARGUMENTS 🎀

  • bat_priv — the bat priv that's holding all the mesh interface information. the main character's whole wardrobe basically 💜
  • ogm_received — the OGM that was previously received and is now getting forwarded. it's been places, it's seen things 🦋
  • orig_node — the originator that has been updated ✨
  • neigh_node — the neigh_node that the OGM came in through, iykyk 🌈
  • if_incoming — the interface this OGM was received on, like, where it entered the chat 🙈
  • if_outgoing — the interface the OGM has to be forwarded to. that's the exit, the departure gate, the slay 💅

⭐ DESCRIPTION ⭐

so what she does is: forward an OGM to an interface — but after having altered the throughput metric and the TTL value contained in it 🔥

and here's the iconic part: the original OGM isn't modified. not one bit. she makes a copy moment and leaves the original untouched, no cap 🙌

ngl bestie this is the important bit — the metrics get tweaked for the forwarded version, but the received packet stays exactly as it was. respect the original, periodt 💖

🦋 SEE ALSO 🦋

okay that's the whole page bestie, go forth and forward those OGMs responsibly 🧚‍♀️
