hi all,
i have to trap some kernel functions like:
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. but when it reurns with 0 , the nameidata->dentry and mnt fields of nameidata structure point to the pathname component. so most probably( m not sure) this will change the stack address and get back to the calling point of link_path_walk().
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. 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?
is there any way in /proc subsystem to check it out?
Please rephrase your question: are you going to find symbol address? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
