cfg80211_li...oc_tid_stats(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, so this one is a kernel API function and it lives in the manual as cfg80211_li...oc_tid_stats(9) (yeah the title's truncated, that's just how the man page renders it, don't come for me 😭). It's giving small-but-load-bearing, so let's get into it.

🎀 NAME 🎀

cfg80211_link_sinfo_alloc_tid_stats — allocate per-tid statistics. that's it, that's the whole job. it allocates. for every tid. stats. slay ✨

🦋 SYNOPSIS 🦋

int cfg80211_link_sinfo_alloc_tid_stats (struct link_station_info
*link_sinfo , gfp_t gfp );

lowkey it returns an int, takes a pointer to a struct link_station_info called link_sinfo, and a gfp_t called gfp. literally the whole signature, no cap. 💅

🌸 ARGUMENTS 🌸

  • link_sinfo — the link station information. this is the thing you're allocating the per-tid stats for, so like, hand it over 🫶
  • gfp — allocation flags. you know the drill, this is the gfp_t vibe check for how the allocation happens — pass your flags and let the function do its thing ✨

⭐ RETURN ⭐

  • 0 on success. we love a clean zero, iconic 👑
  • Non-zero on error. so like, if it's not zero, something went sideways — check it, don't ignore it, fr fr 🙈

okay that's part one done, next part's coming so don't go anywhere 💖

💫 SEE ALSO 💫

Okay so first thing, bestie: the actual source of truth is the kernel file ./include/net/cfg80211.h — that's the mothership, the main character, the whole reason we're here. Start your journey with Introduction(9) and Device registration(9), and then buckle up because this list is long and honestly? kind of iconic of it.

Now the channel-and-rate crew, the ones that set the whole vibe: 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). No cap, this is the foundational stuff.

Then we get into the capability glow-ups — HT, VHT, HE, EHT, UHR, the whole alphabet mafia: 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).

And obviously the band/EDMG/S1G section because we contain multitudes: 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). Obsessed with all of it tbh.

Okay now Actions and configuration — Actions and configuration(9) is the section vibe, and it comes with struct vif_params(9), struct key_params(9), struct cfg80211_chan_def(9), struct cfg80211_tid_cfg(9), struct cfg80211_tid_config(9), struct cfg80211_fils_aad(9), struct cfg80211_set_hw_timestamp(9).

Then the chandef girlies, who are lowkey the backbone of everything: cfg80211_get_chandef_type(9), cfg80211_chandef_create(9), cfg80211_chandef_identical(9), cfg80211_chandef_is_edmg(9), cfg80211_chandef_is_s1g(9), cfg80211_chandef_compatible(9), nl80211_chan_width_to_mhz(9), cfg80211_chandef_get_width(9), cfg80211_chandef_valid(9), cfg80211_chandef_usable(9), cfg80211_chandef_dfs_required(9), cfg80211_chandef_dfs_usable(9), cfg80211_chandef_dfs_cac_time(9), cfg80211_chandef_primary(9), cfg80211_chandef_npca_valid(9), cfg80211_chandef_add_npca(9), cfg80211_chandef_add_dbe(9), nl80211_send_chandef(9), ieee80211_chandef_max_power(9), cfg80211_chandef_s1g_pri_width(9), cfg80211_any_usable_channels(9). Slay, every single one.

Survey, crypto, and the AP-side icons: 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_acl_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).

Then the station lore, which is a whole saga: 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), enum rate_info_flags(9), enum rate_info_bw(9), struct rate_info(9), enum bss_param_flags(9), struct sta_bss_parameters(9), struct cfg80211_txq_stats(9), struct cfg80211_tid_stats(9), struct link_station_info(9), struct station_info(9), struct cfg80211_sar_sub_specs(9), struct cfg80211_sar_specs(9), struct cfg80211_sar_freq_ranges(9), struct cfg80211_sar_capa(9), cfg80211_get_station(9), enum monitor_flags(9), enum mpath_info_flags(9), struct mpath_info(9), enum wiphy_bss_param_flags(9), struct bss_parameters(9), struct mesh_config(9), struct mesh_setup(9), struct ocb_setup(9), struct ieee80211_txq_params(9). That's a lot of structs and every one of them ate, fr fr.

Back to scanning events and BSS management because we're nothing if not thorough: cfg80211_scan_done(9), cfg80211_sched_scan_results(9), cfg80211_sched_scan_stopped(9), cfg80211_sched_scan_stopped_locked(9), cfg80211_inform_bss_frame_data(9), cfg80211_gen_new_bssid(9), cfg80211_is_element_inherited(9), cfg80211_merge_profile(9), enum cfg80211_bss_frame_type(9), cfg80211_get_ies_channel_number(9), cfg80211_ssid_eq(9), cfg80211_inform_bss_data(9), __cfg80211_get_bss(9), cfg80211_get_bss(9), cfg80211_ref_bss(9), cfg80211_put_bss(9), cfg80211_unlink_bss(9), cfg80211_bss_iter(9), cfg80211_rx_mlme_mgmt(9), cfg80211_auth_timeout(9), struct cfg80211_rx_assoc_resp_data(9), cfg80211_rx_assoc_resp(9), struct cfg80211_assoc_failure(9), cfg80211_assoc_failure(9), cfg80211_tx_mlme_mgmt(9), cfg80211_rx_unprot_mlme_mgmt(9), cfg80211_michael_mic_failure(9), cfg80211_ibss_joined(9), cfg80211_notify_new_peer_candidate(9).

RFkill integration, vendor stuff, and test mode, oh my: RFkill integration(9), wiphy_rfkill_set_hw_state_reason(9), wiphy_rfkill_start_polling(9), wiphy_rfkill_stop_polling(9), Vendor commands(9), cfg80211_vendor_cmd_alloc_reply_skb(9), cfg80211_vendor_cmd_reply(9), cfg80211_vendor_cmd_get_sender(9), cfg80211_vendor_event_alloc(9), cfg80211_vendor_event_alloc_ucast(9), cfg80211_vendor_event(9), Test mode(9), cfg80211_testmode_alloc_reply_skb(9), cfg80211_testmode_reply(9), cfg80211_testmode_alloc_event_skb(9), cfg80211_testmode_event(9).

Then the connect/roam/notify hall of fame, aka the plot twists: struct cfg80211_fils_resp_params(9), struct cfg80211_connect_resp_params(9), cfg80211_connect_done(9), cfg80211_connect_bss(9), cfg80211_connect_result(9), cfg80211_connect_timeout(9), struct cfg80211_roam_info(9), cfg80211_roamed(9), cfg80211_port_authorized(9), cfg80211_disconnected(9), cfg80211_ready_on_channel(9), cfg80211_remain_on_channel_expired(9), cfg80211_tx_mgmt_expired(9), cfg80211_sinfo_alloc_tid_stats(9), cfg80211_sinfo_release_content(9), cfg80211_new_sta(9), cfg80211_del_sta_sinfo(9), cfg80211_del_sta(9), cfg80211_conn_failed(9), struct cfg80211_rx_info(9), cfg80211_rx_mgmt_ext(9), cfg80211_rx_mgmt_khz(9), cfg80211_rx_mgmt(9).

Bestie note: that's the whole cross-reference list, no skips, no cuts. If a name is in here, it's in here on purpose — go read the ones you need and hydrate while you're at it. 💅

okay bestie, final stretch — and it's the cross-reference wall of fame 😭 the page literally just drops a massive list of names on you with zero commentary and dips, so here's every single one, untouched, in the exact order it appears. no skips, no merges. read them, they're canon 💅
