trace_signal_generate(9)

💅 trace_signal_generate(9) — Kernel API Manual ✨

🌸 NAME 🌸

trace_signal_generate — called when a signal is generated. That’s literally the whole vibe of this page, bestie. 🎀

🦋 SYNOPSIS 🦋

void trace_signal_generate (int sig , struct kernel_siginfo *info ,
       struct task_struct *task , int group , int result );

🎀 ARGUMENTS 🎀

• sig — signal number. 💖
• info — pointer to struct siginfo. 👀
• task — pointer to struct task_struct. 🫶
• group — shared or private. 🌈
• result — TRACE_SIGNAL_*. ⭐

💜 DESCRIPTION 💜

Okay so the description is short and specific: current process sends a 'sig' signal to 'task' process with SEND_SIG_NOINFO means that si_code is SI_USER, and SEND_SIG_PRIV means that si_code is SI_KERNEL. 🦋

No cap, those two mappings are the whole little story here.
