binder_netlink_report(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the binder_netlink_report page from the Kernel API Manual — this is the little function that spills the tea ☕ about a transaction that flopped, and it does it over netlink. buckle up, it's short but it matters 🎀

✨ NAME ✨

binder_netlink_report — report a transaction failure via netlink 🔥

No cap, that's the whole job. A transaction failed, and this is how the kernel tells somebody about it.

🌸 SYNOPSIS 🌸

void binder_netlink_report (struct binder_proc *proc , struct
binder_transaction *t , u32 data_size , u32 error );

it's giving "void, returns nothing, move along" 💅

🦋 ARGUMENTS 🦋

  • proc — the binder proc sending the transaction 👑
  • t — the binder transaction that failed 😭 (rip bestie)
  • data_size — the user provided data size for the transaction 🍓
  • error — enum binder_driver_return_protocol returned to sender 📬

💜 DESCRIPTION 💜

okay this is the part you actually need to read, so pay attention 🙈

🚨 Note that t->buffer is not safe to access here, as it may have been released (or not yet allocated).

like, literally do not touch it. it's giving "he's not even there anymore" 💀

Callers should guarantee all the transaction items used here are safe to access. that's on you, bestie, not on this function — do your vibe check before you call it ✨
