STRUCT CFG80211_ACL_DATA(9)

🦋 struct cfg80211_acl_data(9) 🦋

straight outta the Kernel API Manual, bestie — and it's giving “access control list data” realness. 💅

🌸 NAME 🌸

struct cfg80211_acl_data — Access control list data. That’s the whole vibe: this struct is the ACL data container, periodt.

✨ SYNOPSIS ✨

okay so here’s the exact struct layout, copied character-for-character because we do not play fast and loose with code:

struct cfg80211_acl_data {
    enum nl80211_acl_policy acl_policy;
    int n_acl_entries;
    struct mac_address mac_addrs[];
};

Three members, one cute little package. Let’s meet them properly. 🫶

👑 Members 👑

acl_policy — this is an enum nl80211_acl_policy, and it’s the ACL policy to be applied on the station's entry specified by mac_addr. So yeah, it’s the “which policy are we applying here?” field. ✨
n_acl_entries — an int, bestie, and it’s literally the Number of MAC address entries passed. That’s the count of MAC address entries in the mix. 🔢
mac_addrs — this is a struct mac_address mac_addrs[], aka the List of MAC addresses of stations to be used for ACL. The square brackets are right there in the struct, no cap. 🎀

💖 SEE ALSO 💖

Okay bestie, SEE ALSO is basically the group chat of every related kernel doc, and we are NOT leaving anyone on read. It starts with Kernel file ./include/net/cfg80211.h, and then the whole squad rolls in:

Introduction(9), Device registration(9), enum ieee80211_channel_flags(9), struct ieee80211_channel(9), enum ieee80211_rate_flags(9), enum ieee80211_bss_type(9), enum ieee80211_privacy(9), struct ieee80211_rate(9), struct ieee80211_he_obss_pd(9), struct cfg80211_he_bss_color(9), struct ieee80211_sta_ht_cap(9), struct ieee80211_sta_vht_cap(9), struct ieee80211_sta_he_cap(9), struct ieee80211_eht_mcs_nss_supp(9), struct ieee80211_sta_eht_cap(9), struct ieee80211_sta_uhr_cap(9), struct ieee80211_sband_iftype_data(9), enum ieee80211_edmg_bw_config(9), struct ieee80211_edmg(9), struct ieee80211_sta_s1g_cap(9), struct ieee80211_supported_band(9), _ieee80211_set_sband_iftype_data(9), ieee80211_set_sband_iftype_data(9), for_each_sband_iftype_data(9), ieee80211_get_sband_iftype_data(9), ieee80211_get_he_iftype_cap(9), ieee80211_get_he_6ghz_capa(9), ieee80211_get_eht_iftype_cap(9), ieee80211_get_uhr_iftype_cap(9), wiphy_read_of_freq_limits(9).

Then we slide into the Actions and configuration corner, and yes, it is giving “linked list of destiny”:

The survey / crypto / beacon / AP / station-params part of the chat is also fully present, no one got muted:

enum survey_info_flags(9), struct survey_info(9), struct cfg80211_crypto_settings(9), struct cfg80211_mbssid_config(9), struct cfg80211_mbssid_elems(9), struct cfg80211_rnr_elems(9), struct cfg80211_beacon_data(9), struct cfg80211_fils_discovery(9), struct cfg80211_unsol_bcast_probe_resp(9), struct cfg80211_s1g_short_beacon(9), struct cfg80211_ap_settings(9), struct cfg80211_ap_update(9), struct cfg80211_csa_settings(9), struct cfg80211_color_change_settings(9), struct iface_combination_params(9), enum station_parameters_apply_mask(9), struct sta_txpwr(9), struct link_station_parameters(9), struct link_station_del_parameters(9), struct cfg80211_ttlm_params(9), struct station_parameters(9), struct station_del_parameters(9), enum cfg80211_station_type(9), cfg80211_check_station_change(9).
