PROBE::TCPMIB.CURR(3stap)

💖 probe::tcpmib.CurrEstab 💖

okay bestie, welcome to PROBE::TCPMIB.CURR(3stap) — yes that's the manual page name, yes it's a mouthful, no we are not changing it. it lives in the SNMP Information Tapset and it is genuinely so much simpler than it looks. sit down, hydrate, let's go 🫶

✨ NAME ✨

probe::tcpmib.CurrEstab — update the count of open sockets 💅

like. that's the whole job. it updates the count of open sockets. main character behavior honestly 👑

---

🌸 SYNOPSIS 🌸

probe tcpmib.CurrEstab {}

no args, no drama, no flags. just vibes. the empty braces are literally the point 🎀

---

🦋 VALUES 🦋

the probe hands you these, and you should lowkey care about both:

• sk — a pointer to the struct sock being acted on. it's giving "here's the socket, do something iconic with it" ✨
• op — the value to be added to the counter. the default value is 1. so if you don't say anything, it just adds one, like a polite little gremlin 🍓

---

💜 DESCRIPTION 💜

so here's the tea, fr fr:

the packet pointed to by skb gets filtered by the function tcpmib_filter_key. that's the bouncer at the door, checking IDs, deciding who's allowed in 🧚

and if the packet passes the filter, it gets counted in the global CurrEstab. that global is equivalent to SNMP's MIB TCP_MIB_CURRESTAB. no cap. that's the whole flow — packet shows up, filter does its thing, passing packets get tallied, the global counter goes up 🎀
