Message-ID: To: kernelnewbies@lists.kernelnewbies.org List-Id: kernelnewbies.lists.kernelnewbies.org Hello everyone, I am going to hook a system call like 'read' or 'send' by modifying the sys_call_table, but it seems that the sys_call_table is in read only page, how can I set modify the sys_call_table ? Or if there any method that I can use to hook a system call in module without modify the kernel source?
