tipc_crypto_key_synch(9)

welcome to tipc_crypto_key_synch(9) from the Kernel API Manual — this is your bestie’s guide to the function that keeps key data in sync, and yes, it’s giving main character energy. 💅✨

✨ NAME ✨

tipc_crypto_key_synch — synch own key data according to peer key status. periodt. 💖

🦋 SYNOPSIS 🦋

void tipc_crypto_key_synch (struct tipc_crypto *rx , struct sk_buff *skb );

🌸 ARGUMENTS 🌸

• rx — RX crypto handle. 🫶
• skb — TIPCv2 message buffer (incl. the ehdr from peer). 💌

🎀 DESCRIPTION 🎀

okay so here’s the tea, bestie: this function updates the peer node related data as the peer RX active key has changed, so the number of TX keys’ users on this node are increased and decreased correspondingly. literally keeping the key-user count from doing a chaos. 😭🔥

It also considers if peer has no key, then we need to make own master key (if any) taking over — i.e. starting grace period — and also trigger key distributing process. iconic behavior, ngl. 💀👑
