Subject: How to hook the system call?
Date: Wed, 23 Nov 2011 16:40:14 +0800 [thread overview]
Message-ID: <CAAdM-RWsvJ_EQUfmx8daZbahH54FAzAm4FniGCWbKK_z8mN4TQ@mail.gmail.com> (raw)
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?
Thanks!
