scsi_cmd_allowed(9)

🎀 scsi_cmd_allowed(9) 🎀

hii bestie 🫶 okay so welcome to the Kernel API Manual, where today's main character is scsi_cmd_allowed(9). This one's a little vibe check for SCSI commands — no cap, it's the function that asks whether a command is allowed. ✨

🌸 NAME 🌸

scsi_cmd_allowed — check if the given command is allowed. That's the name, that's the whole assignment, periodt. 💅

💖 SYNOPSIS 💖

bool scsi_cmd_allowed (unsigned char *cmd , bool open_for_write );

🦋 ARGUMENTS 🦋

• cmd — the SCSI command to check. it's giving "put it in the vibe check" energy, lowkey. 👀
• open_for_write — is the file / block device opened for writing? literally the question being asked here, bestie. 🫶

✨ DESCRIPTION ✨

okay so here's the tea ☕: only a subset of commands are allowed for unprivileged users. Commands used to format the media, update the firmware, etc. are not permitted. so no sneaky media-formatting, no firmware glow-up, etc. — those are a hard no for the unprivileged crowd. 🚫💀

🔥 RETURN 🔥

true if the cmd is allowed, otherwise false. simple as that, bestie — slay. ✅❌
