mesh_path_lookup(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mesh_path_lookup (9) — from the Kernel API Manual 🎀

Ok so bestie, gather round, because today we're looking up a path in the mesh path table and honestly? It's giving essential infrastructure. ✨

🌸 NAME 🌸

mesh_path_lookup — look up a path in the mesh path table, no cap 🔍

✨ SYNOPSIS ✨

struct mesh_path * mesh_path_lookup (struct ieee80211_sub_if_data *sdata
, const u8 *dst );

🦋 ARGUMENTS 🦋

  • sdata — the local subif, like, the sub-iface you're working with 💖
  • dst — the hardware address of the destination, and yes it's ETH_ALEN length, so don't @ me with a shorter one 🙈

👑 RETURN 👑

It hands you back a pointer to the mesh path structure 🫶 — or NULL if it wasn't found. That's it. That's the vibe check.

💜 DESCRIPTION 💜

Locking: you must call this within a read RCU section. Not optional, not a suggestion, not a "maybe later" — fr fr, respect the RCU section or perish 😭🔥

🌈 SEE ALSO 🌈

The kernel file ./net/mac80211/mesh_pathtbl.c is where all the magic lives, and here's the whole squad it runs with:

💀 Reminder bestie: read RCU section or it doesn't count. That's the whole locking contract and she is not flexible about it.

Okkk that's the page! 🧚 Signing off from ./net/mac80211 in October 2026, brought to you by the mesh_path_lookup(9) girlies — slay, stay safe, and may all your lookups return non-NULL 💅💖🍓
