run ./inject.py kmalloc -v '__x64_sys_mount() gets the error: "math between map_value pointer and register with unbounded min value is not allowed", as the array len is 2:
./inject.py kmalloc -v '__x64_sys_mount()
struct pid_struct { u64 curr_call; /* book keeping to handle recursion */ u64 conds_met; /* stack pointer */ u64 stack[2]; };
but in __x64_sys_mount_exit
__x64_sys_mount_exit
/* * Generate exit logic */ if (p->conds_met < 1 || p->conds_met >= 3) return 0; if (p->stack[p->conds_met - 1] == p->curr_call) p->conds_met--;
The check for the upper bound of the array is 3.
@chenhengqi @yonghong-song PTAL, thanks!
