STRUCT BATADV_PRIV_BLA(9)

🦋 struct batadv_priv_bla(9) 🦋

okay bestie, welcome to the Kernel API Manual page for struct batadv_priv_bla(9) — the per mesh interface bridge loop avoidance data. It's the BLA backstage pass, basically. We're gonna read it top to bottom, no cap 💅✨

🌸 NAME 🌸

struct batadv_priv_bla — per mesh interface bridge loop avoidance data.

That's the whole vibe: it's the per mesh interface bridge loop avoidance data, and it's lowkey iconic 👑

⭐ SYNOPSIS ⭐

Here's the struct in all its glory — field names are sacred, don't rename a single one:

struct batadv_priv_bla {
    atomic_t num_requests;
    spinlock_t num_requests_lock;
    struct batadv_hashtable *claim_hash;
    struct batadv_hashtable *backbone_hash;
    u8 loopdetect_addr[ETH_ALEN];
    unsigned long loopdetect_lasttime;
    atomic_t loopdetect_next;
    struct batadv_bcast_duplist_entry
bcast_duplist[BATADV_DUPLIST_SIZE];
    int bcast_duplist_curr;
    spinlock_t bcast_duplist_lock;
    struct batadv_bla_claim_dst claim_dest;
    struct delayed_work work;
 };

💖 Members 💖

• num_requests — number of bla requests in flight, literally keeping tabs on what's in the air.
• num_requests_lock — the lock for the update of num_requests + batadv_backbone_gw::state + batadv_backbone_gw::wait_periods update. Yes, all of that, and it's giving very busy bouncer energy.
• claim_hash — hash table containing mesh nodes this host has claimed.
• backbone_hash — hash table containing all detected backbone gateways.
• loopdetect_addr — MAC address used for own loopdetection frames.
• loopdetect_lasttime — time when the loopdetection frames were sent.
• loopdetect_next — how many periods to wait for the next loopdetect process.
• bcast_duplist — recently received broadcast packets array, specifically for broadcast duplicate suppression.
• bcast_duplist_curr — index of last broadcast packet added to bcast_duplist.
• bcast_duplist_lock — lock protecting bcast_duplist & bcast_duplist_curr.
• claim_dest — local claim data, e.g. claim group.
• work — work queue callback item for cleanups & bla announcements.
