report_bad_packet(9)

💅 report_bad_packet(9) — like, the Kernel API Manual page, bestie 💖

okay so real talk, this is the man page for report_bad_packet, straight out of the Kernel API Manual ✨ yes the man page section 9 one, we love a kernel-internals moment 🎀 stay with me, it's actually so simple.

---

🌸 NAME 🌸

report_bad_packet — literally just: Report bad packets 🫶

---

✨ SYNOPSIS ✨

bestie the signature is exactly this, no cap, copy it character for character:

void report_bad_packet (struct ishtp_cl *hid_ishtp_cl , void *recv_buf ,
size_t cur_pos , size_t payload_len );

---

🦋 ARGUMENTS 🦋

four args, four vibes, let's go 💅

• hid_ishtp_cl — the client instance you're pulling stats from 👑
• recv_buf — the raw received host interface message, straight off the wire, no filter 💀
• cur_pos — the current position index in the payload, like a little cursor going "we are HERE" 📍
• payload_len — how long the payload is expected to be 🌸 (key word: expected, iykyk)

---

🧚 DESCRIPTION 🧚

so what does it do?? it dumps an error in case a bad packet is received 🚨 that's the whole thing. packet goes bad ➡️ error gets dumped. the way that's literally it 😭 iconic behaviour honestly, no notes.

fr fr this is the "something smells off in the packet" alarm. it doesn't fix anything, it just tells you 🫶
