ENUM IEEE80211_PRIVACY(9)
โจ enum ieee80211_privacy(9) โจ
okay so bestie, welcome to the Kernel API Manual โ this is the page for enum ieee80211_privacy(9) and honestly it's a short one but it's important, so pay attention ๐
๐ NAME ๐
enum ieee80211_privacy โ the BSS privacy filter, aka the little vibe check that decides whether a BSS is giving "locked down" or "open to literally anyone" ๐
๐ฆ SYNOPSIS ๐ฆ
enum ieee80211_privacy {
IEEE80211_PRIVACY_ON ,
IEEE80211_PRIVACY_OFF ,
IEEE80211_PRIVACY_ANY
};
likeโฆ look at her. three constants. no notes. iconic ๐
๐ธ Constants ๐ธ
these are the three members of the enum, and each one is a different mood for your privacy filter ๐ซถ
IEEE80211_PRIVACY_ONโ privacy bit set โจ (the BSS is privacy-on, periodt)IEEE80211_PRIVACY_OFFโ privacy bit clear ๐ (privacy-off, no cap)IEEE80211_PRIVACY_ANYโ the wildcard value for matching any privacy setting ๐ฏ like, doesn't matter if it's on or off, this one matches everything, iykyk
ngl the wildcard one is the main character here โ IEEE80211_PRIVACY_ANY is literally "idc, match whatever" and that's such a mood ๐
more coming bestie, don't go anywhere ๐ง
๐ SEE ALSO ๐
okay bestie, this is the part of the page where it stops explaining and just drops the whole bibliography on you ๐ and likeโฆ it's a lot. it's giving "my README has 400 badges" energy. but every single one of these is a real page you can go read, so we're listing them all, no skips, no cap โจ
- kernel file โ
./include/net/cfg80211.h
that file is the whole reason this list exists, iykyk ๐ซถ and here's the first batch, the band-and-capability girlies:
