llc_process_tmr_ev(9)

✨ NAME ✨

llc_process_tmr_ev — timer backend. This is the llc_process_tmr_ev(9) page from the Kernel API Manual, bestie. 💖

🌈 SYNOPSIS 🌈

void llc_process_tmr_ev (struct sock *sk , struct sk_buff *skb );

🎀 ARGUMENTS 🎀

• sk — active connection 🫶
• skb — occurred event ✨

🔥 DESCRIPTION 🔥

Okay so this function is called from timer callback functions, periodt. ⏰

When the connection is busy (like, during sending a data frame), the timer expiration event must be queued. That part is non-negotiable, no cap. Otherwise, this event can be sent to the connection state machine. 🌸

Queued events will be processed by the llc_backlog_rcv function after sending the data frame — so they get handled after the frame goes out, bestie. 💅
