vbg_set_sess...capabilities(9)

💅 vbg_set_sess...capabilities(9) 💅

okay so welcome to the Kernel API Manual entry for vbg_set_sess...capabilities(9), bestie. This is the page for vbg_set_session_capabilities, and it’s literally about setting the guest capabilities for a session. It also takes the session mutex — noted, respected, iconic. ✨

🌸 NAME 🌸

vbg_set_session_capabilities — sets the guest capabilities for a session. Takes the session mutex.

---

✨ SYNOPSIS ✨

int vbg_set_session_capabilities (struct vbg_dev *gdev , struct
vbg_session *session , u32 or_mask , u32 not_mask , bool
session_termination );

---

💖 ARGUMENTS 💖

• gdev — the Guest extension device. That’s the vibe.
• session — the session. Main character energy, fr fr.
• or_mask — the capabilities to add. Slay.
• not_mask — the capabilities to remove. Bye bestie.
• session_termination — set if we’re called by the session cleanup code. This tweaks the error handling so we perform proper session cleanup even if the host misbehaves. 🫶

---

🎀 RETURN 🎀

0 or a negative errno value. That’s the whole mood.
