sys_lsm_get_self_attr(9)

💖 sys_lsm_get_self_attr(9) 💖

okay so bestie, welcome to sys_lsm_get_self_attr(9) from the Kernel API Manual — this is the one that returns the current task's security module attributes, and yes it ate. ✨

✨ NAME ✨

sys_lsm_get_self_attr — returns the current task's security module attributes. No cap, that's the whole vibe. 💅

🎀 SYNOPSIS 🎀

long sys_lsm_get_self_attr (unsigned int attr , struct lsm_ctx __user *
       ctx , u32 __user * size , u32 flags );

💅 ARGUMENTS 💅

• attr — which attribute to return. simple as that, bestie.
• ctx — the user-space destination for the information, or NULL. yes, NULL is allowed, icon behavior.
• size — pointer to the size of space available to receive the data. it's giving capacity check.
• flags — special handling options. LSM_FLAG_SINGLE means only attributes associated with the LSM identified in the passed ctx get reported. iykyk.

🌸 DESCRIPTION 🌸

okay so here's the tea: this returns the calling task's LSM contexts. 💖 On success, it returns the number of ctx array elements. That number can be zero if there are no LSM contexts assigned — not a whole crisis, just a cute empty-array moment. 🫶

If size is insufficient to contain the return data, -E2BIG is returned and size is set to the minimum required size. In all other cases, a negative value indicating the error is returned. 💀
