💅 efx_filter_get_filter_safe(9)

okay so this is a page from the Kernel API Manual and it's all about efx_filter_get_filter_safe — the safe-girl version of grabbing a filter by its ID 🎀

---

✨ NAME ✨

efx_filter_get_filter_safe — retrieve a filter by ID, but like… carefully 🙈

---

🌸 SYNOPSIS 🌸

int efx_filter_get_filter_safe (struct efx_nic *efx , enum
       efx_filter_priority priority , u32 filter_id , struct efx_filter_spec
       *spec );

periodt, that's the whole signature, no notes 💅

---

🦋 ARGUMENTS 🦋

• efx — the NIC from which to remove the filter. yeah that's literally what the page says bestie, don't come for me 😭
• priority — the priority of the filter, exactly as you passed it to efx_filter_insert_filter
• filter_id — the ID of the filter, exactly as it came back from efx_filter_insert_filter
• spec — the buffer where the filter specification gets stored 📥

---

💖 DESCRIPTION 💖

bestie listen. this function range-checks filter_id first. that's the whole flex 💪

so it is safe to call with a value passed from userland — like, actually safe, not "safe if you squint" safe. no cap. 🫶
