tipc_sk_filtering(9)

💖 tipc_sk_filtering 💖

okay so this is a page from the Kernel API Manual — yes bestie, the kernel has lore too — and it's all about tipc_sk_filtering, a lil function whose whole job is checking whether a socket should be traced. that's it. that's the vibe. 🎀

---

✨ SYNOPSIS ✨

bool tipc_sk_filtering (struct sock *sk );

literally one argument, returns a bool, we love a low-maintenance king 👑

---

🌸 ARGUMENTS 🌸

• sk — the socket to be examined 👀 that's the one getting the vibe check

---

🦋 DESCRIPTION 🦋

so here's the tea: sysctl_tipc_sk_filter gets used as the socket tuple for filtering. and that tuple is made of these five things, in this exact order:

• portid
• sock type
• name type
• name lower
• name upper

that's the whole description, no cap. the sysctl is the tuple, the tuple is the filter, periodt. 💅

---

💜 RETURN 💜

it hands back true if the socket meets the socket tuple data — and quick note, a value of 0 means 'any' ✨ — or when there is no tuple set at all (that's all = 0). otherwise? false. simple as. 🫶

ok real talk: nothing here is scary, but don't go inventing tuple values in your head — 0 means 'any' and no tuple set is all = 0, and that's exactly what the page says, so keep it that way 🙈
