VOP_REVOKE(9)

💖 VOP_REVOKE — bestie, it's time to revoke some access 💖

okay so this is the VOP_REVOKE(9) page, from the Kernel Developer's Manual, and it's literally about kicking devices out of the group chat. let's get into it 🎀

✨ NAME ✨

VOP_REVOKE — revoke access to a device and its aliases

🌸 SYNOPSIS 🌸

#include <sys/param.h>
#include <sys/vnode.h>

int
VOP_REVOKE(struct vnode *vp, int flags);

🦋 DESCRIPTION 🦋

so here's the tea ☕ — VOP_REVOKE() will administratively revoke access to the device specified by vp, and also to any aliases that got created via make_dev_alias(9). like, the whole friend group, not just the one device. 💅

any further file operations on any of these devices by processes that have them open will nominally fail. so if a process is still holding it open and tries to do stuff? yeah, that's a no. 🙈

now the flags — they must be set to REVOKEALL to signify that all access will be revoked. that's the vibe. any other value is invalid, full stop, periodt. 🚫

🔒 LOCKS 🔒

the vp must be exclusively locked on entry, and it will remain locked upon return. so don't be out here unlocking it on your way out, bestie — it stays locked, that's the deal. 🔐
