STRUCT BRCMF_PMKSA_V3(9)

💅 struct brcmf_pmksa_v3(9) — PMK Security Association

okay bestie so this is a page from the Kernel API Manual, and it's about struct brcmf_pmksa_v3 — literally the PMK Security Association struct. it's giving wireless-driver internals, it's giving "I read headers for fun", and honestly? obsessed. 🎀

✨ NAME ✨

struct brcmf_pmksa_v3 — PMK Security Association

like, the whole vibe of the struct in four little words. slay. 💅

---

🦋 SYNOPSIS 🦋

here's the shape of it, copied exactly, no cap:

struct brcmf_pmksa_v3 {
    u8 bssid[ETH_ALEN];
    u8 pmkid[WLAN_PMKID_LEN];
    u8 pmkid_len;
    u8 pmk[WLAN_PMK_LEN_SUITE_B_192];
    u8 pmk_len;
    __le16 fils_cache_id;
    u8 pad;
    struct brcmf_ssid8_le ssid;
    __le32 time_left;
 };

look at her. nine-ish fields of pure main character energy. 🔥

🌸 Members 🌸

okay so let's go field by field, because every single one matters:

• bssid — the AP's BSSID. that's the basic service set identifier, the AP's whole identity, her government name basically. 👑
• pmkid — the PMK ID. that's it, that's the field.
• pmkid_len — the length of the PMK ID. yes bestie, a length for the ID. we love a self-describing struct.
• pmk — PMK material for FILS key derivation. it's the actual crypto-ish material, okay, treat it with respect. ✨
• pmk_len — length of PMK data. the number that tells you how much of pmk is real.
• fils_cache_id — the FILS cache identifier. FILS said "I'll cache it" and this is the id of that cache. iconic. 🦋
• pad — it's in the struct, it's padding-shaped, and the manpage literally gives it no description at all. so I'm not gonna invent one for you, ngl. it's just... there. 🙈
• ssid — the AP's SSID. the name you actually see in the wifi list, the one you click on at a café and immediately regret.
• time_left — remaining time until expiry. and the page is very specific here: 0 = expired, ~0 = no expiry. memorize that, it's a vibe check in numeric form. 💀

🫶 reminder that pad has no documented meaning on this page — don't go assigning lore to it.

and that's the page, bestie! 🧚 source/version line goes a little something like ./drivers/net/wireless/broadco... and the date stamp says October 2026, and the footer is still repping struct brcmf_pmksa_v3(9) — so yeah, that's the whole read. go forth and associate your PMKs responsibly. 🌈✨
