STRUCT CFG80211_MATCH_SET(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct cfg80211_match_set(9) 💅

ok so this is from the Kernel API Manual, bestie — and it's literally about sets of attributes to match. that's the whole NAME section, no cap: sets of attributes to match. it's giving "we're gonna filter your scan results" energy and honestly? iconic. 🎀

This page is long so it comes in 3 parts — buckle up, part 1 is the setup arc. ✨

✨ SYNOPSIS ✨

okay so here's the actual struct, and yes it's exactly this, copy it character for character, i don't make the rules (i do enforce them tho 🫶):

struct cfg80211_match_set {
    struct cfg80211_ssid ssid;
    u8 bssid[ETH_ALEN];
    s32 rssi_thold;
};

like. three members. that's it. she's small but she's doing a lot. main character energy in eleven lines. 🌸

🦋 Members 🦋

  • ssid — the SSID you wanna match, bestie. but listen: it may be zero-length if you're doing a BSSID match instead, or if you're doing no match at all (i.e. RSSI only). so an empty SSID isn't a bug, it's a choice. 💖
  • bssid — the BSSID you wanna match. same deal, flipped: it may be all-zero BSSID if you're matching on SSID instead, or again if there's no match at all (RSSI only). zeroed out = vibes only, no BSSID hunting. ✨
  • rssi_thold — lowkey a bouncer for your scan results: don't report scan results below this threshold, and it's measured in s32 dBm. so anything weaker than your number just doesn't get in the group chat. 🙈

so that's part 1 — the struct itself and who's who in the friend group. part 2 and part 3 are coming, don't go anywhere. 💜

🌈 SEE ALSO 🌈

Okay bestie, this is the part where the page just… names everyone in the group chat. 💅 Every single one of these lives in the kernel file ./include/net/cfg80211.h — that's the mothership — and each one has its own (9) page waiting for you to fall down a rabbit hole. No cap, it's a lot of them. Buckle up. 🎀

Yeah okay that's the whole extended friend group 💅 like genuinely every single one of them, no cap, I didn't skip a single mutual. There's struct-prefixed ones and plain-function ones mixed in there and I kept them exactly as they came, because we do not deadname anybody's identifier in this house 🫶

bestie if one of these names makes you go "wait what does that even do" — that's literally what the (9) is for, go click it. I'm not out here guessing at behaviour for you, that would be so not slay of me 😭

Okay that's a wrap on this whole page, and I'm lowkey emotional about it 🥹 You made it to the end of struct cfg80211_match_set(9) — that's main character energy fr fr.

Where it lives: ./include/net 🎀. What we're calling this era: October 2026 (yes, the future, we're ahead of the timeline, iconic). And the headline, the title card, the whole vibe: struct cfg80211_match_set(9) ✨

Now go forth and match some sets, bestie. Slay 💖🌸🦋
