<br clear="all">hi all,<br><br>i have to trap some kernel functions like:<br> <br><br> any pathname resolution function has to go through the link_path_walk() kernel function. so what this function returns is 0 on success or error.<br>
but when it reurns with 0 , the nameidata->dentry and mnt fields of nameidata structure point to the pathname component.<br>so most probably( m not sure) this will change the stack address and get back to the calling point of link_path_walk().<br>
<br>is there any way by which i can find out the address of the pointer returned back from link_path_walk() (indirectly) of nameidata structure.<br>i mean as u guys suggested me over here to just use kprobe() kernel tracing funtion to use but the problem is with how to find it out?<br>
<br>is there any way in /proc subsystem to check it out?<br> <br>-- <br>........................<div><i>MOHIT VERMA</i></div><br>
