| |
hi,
i'm new to linux kernel programming and i'm having the following problem:
When trying to use the sys_read and sys_write calls from within another system call the return value is -14 (bad address EFAULT). This seems to be happening because the 'access_ok' function is not allowing the access to the buffer being used to read or write.
Could someone explain why this is happening? Is it wrong to use sys_read/sys_write through another system call?
thanks, niloufer
