idpf_mac_fi...sync_handler(9)

idpf_mac_fi...sync_handler(9) 💅✨

Okay bestie, welcome to the Kernel API Manual page for idpf_mac_fi...sync_handler(9) — yes, the title is literally abbreviated like that with the dots, and the function underneath is idpf_mac_filter_async_handler. We're so back. 🦋

🌸 NAME 🌸

idpf_mac_filter_async_handler — Async callback for mac filters 💖

🎀 SYNOPSIS 🎀

void idpf_mac_filter_async_handler (void *ctx , struct kvec *buff , int status );

✨ ARGUMENTS ✨

• ctx — controlq context structure. The controlq context, periodt 🫶
• buff — response buffer pointer and size. Pointer and size, iconic combo ✨
• status — async call return value. The async call's receipts 💅

👑 DESCRIPTION 👑

So here's the situation: in some scenarios the driver can't sleep and wait for a reply — for example when the stack is holding rtnl_lock — when adding a new mac filter. That puts us in a difficult situation to deal with errors returned on the reply. The best we can ultimately do is remove it from our list of mac filters and report the error. 😭 No cap, that's the whole move.
