syscall_set_arguments(9)

💖 NAME 💖

okay so this is syscall_set_arguments(9) from the Kernel API Manual, bestie — welcome to the page where we change a syscall parameter 💅

syscall_set_arguments — change system call parameter value ✨

---

🎀 SYNOPSIS 🎀

void syscall_set_arguments (struct task_struct *task , struct pt_regs *regs , const unsigned long *args );

---

🦋 ARGUMENTS 🦋

• task — task of interest, must be in system call entry tracing 👀
• regs — task_pt_regs of task
• args — array of argument values to store 🎀

---

🌸 DESCRIPTION 🌸

Okay so real talk: this changes 6 arguments to the system call. The first argument gets value args[0], and so on — you get the vibe ✨

⚠️ It's only valid to call this when task is stopped for tracing on entry to a system call, due to SYSCALL_WORK_SYSCALL_TRACE or SYSCALL_WORK_SYSCALL_AUDIT. That is not a suggestion, bestie — that's the rule 💀
