smk_write_cipso2(9)

💖 NAME 💖

okay bestie, this page is for smk_write_cipso2(9) from the Kernel API Manual — it’s the write() hook for /smack/cipso2 ✨

🌸 SYNOPSIS 🌸

ssize_t smk_write_cipso2 (struct file *file , const char __user *buf ,
       size_t count , loff_t *ppos );

🎀 ARGUMENTS 🎀

• file — a file pointer, but bestie it is not actually used 🙈
• buf — where to get the data from.
• count — bytes sent.
• ppos — where to start.

🦋 DESCRIPTION 🦋

Okay so the vibe check here is simple: it accepts only one cipso rule per write call. No cap. It returns the number of bytes written or an error code, as appropriate — literally that's the whole description, and it ate 💅
