ENUM BATADV_TT_CLIENT_FLAGS(9)

✨ enum batadv_tt_client_flags(9) ✨

okay bestie so this is a page from the Kernel API Manual and it's literally all about enum batadv_tt_client_flags — the TT client specific flags. tiny little bits, huge main character energy 💅

🎀 NAME 🎀

enum batadv_tt_client_flags — TT client specific flags, periodt.

---

🦋 SYNOPSIS 🦋

enum batadv_tt_client_flags {
    BATADV_TT_CLIENT_DEL ,
    BATADV_TT_CLIENT_ROAM ,
    BATADV_TT_CLIENT_WIFI ,
    BATADV_TT_CLIENT_ISOLA ,
    BATADV_TT_CLIENT_NOPURGE ,
    BATADV_TT_CLIENT_NEW ,
    BATADV_TT_CLIENT_PENDING ,
    BATADV_TT_CLIENT_TEMP

};

so yeah, eight constants, all lowercase-screaming at you. icons only, no cap 🌈

🌸 Constants 🌸

• BATADV_TT_CLIENT_DEL — the client has to be deleted from the table. it's giving eviction notice 😭
• BATADV_TT_CLIENT_ROAM — the client roamed to/from another node, and the new update telling its new real location has not been received/sent yet. so it's in transit, lowkey lost 🧚
• BATADV_TT_CLIENT_WIFI — this client is connected through a wifi interface. this info is used by the “AP Isolation” feature. yes it snitched, and yes it served 🫶
• BATADV_TT_CLIENT_ISOLA — this client is considered “isolated”. this info is used by the Extended Isolation feature. alone but iconic 💜
• BATADV_TT_CLIENT_NOPURGE — this client should never be removed from the table. it's protected, it's cherished, it stays 🎀
• BATADV_TT_CLIENT_NEW — this client has been added to the local table but has not been announced yet. brand new arrival, no introduction text 😳
• BATADV_TT_CLIENT_PENDING — this client is marked for removal but it is kept in the table for one more originator interval for consistency purposes. it got a stay of execution fr fr 💀
• BATADV_TT_CLIENT_TEMP — this global client has been detected to be part of the network but no node has already announced it. found in the wild, undisclosed ✨

🌟 Description 🌟

okay so here's the tea on the bit layout ☕

Bits from 0 to 7 are called remote flags because they are sent on the wire. like, actually transmitted, on the network, for everyone to see 💫

Bits from 8 to 15 are called local flags because they are used for local computations only. just for us, private vibes 🙈

Bits from 4 to 7 — a subset of remote flags — are ensured to be in sync with the other nodes in the network. to achieve this goal these flags are included in the TT CRC computation. so yeah, synchronisation is a whole commitment 🔥
