💅 proc_int_conv(9) — Kernel API Manual energy 💅

okay so bestie, this is proc_int_conv(9) from the Kernel API Manual, and it's literally about changing a user or kernel pointer based on direction. slay. let's get into it 🫶

✨ NAME ✨

proc_int_conv — change user or kernel pointer based on direction. no cap, that's the whole name-vibe 💖

🌸 SYNOPSIS 🌸

int proc_int_conv (bool *negp , ulong *u_ptr , int *k_ptr , int dir ,
const struct ctl_table *tbl , bool k_ptr_range_check , int
(*user_to_kern)(const bool *negp, const ulong *u_ptr, int *k_ptr) , int
(*kern_to_user)(bool *negp, ulong *u_ptr, const int *k_ptr) );

🎀 ARGUMENTS 🎀

  • negp — will be passed to uni-directional converters. yes bestie, it gets handed off 💌
  • u_ptr — pointer to user variable. user-side pointer, iconic.
  • k_ptr — pointer to kernel variable. kernel-side pointer, main character.
  • dir — TRUE if this is a write to the sysctl file. direction check, periodt.
  • tbl — the sysctl table. the table in question 🪑
  • k_ptr_range_check — check range for k_ptr when TRUE. only when TRUE, got it? 🔥
  • user_to_kern — callback used to assign value from user to kernel var. the u→k callback 🦋
  • kern_to_user — callback used to assign value from kernel to user var. the k→u callback 🧚

💫 DESCRIPTION 💫

okay so here's the actual tea ☕: when direction is kernel to user, then the u_ptr is modified. when direction is user to kernel, then the k_ptr is modified. that's the pointer glow-up depending on which way the direction is going, bestie 💅✨

✅ RETURN ✅

0 on success. that's it, that's the return. slay 💖
