Hi,
I have a question about a kernel module that I wrote on RH6.2 . In this
module, I am
intercepting the open system call and reading the /proc directory. The
module is working
when i do an insmod. It also works when I type some commands like ls,.. etc.
I am running
apache web server on the same system. When I send many requests (in a
forever loop) to the
server,the system crashes due to my module.
Please tell me if anything is wrong with the function given below. Am I
making a mistake like reading the directory while it is being written?
I am very new to writing kernel modules.
I would really appreciate a reply.
Thanks in advance,
Femitha.
static void readproc1(void)
{
int i,fd,res;
struct my_dentry ent={"/proc/",1};
struct file* file;
mm_segment_t oldfs;
struct inode *inode;
file = filp_open_R3418d8a1("/proc",O_RDONLY,0600);
inode = file->f_dentry->d_inode;
for(i=0;i<=1;i++){
res = file->f_op->readdir(file,(void *)&ent,my_filldir);
}
if (file) filp_close_R9b838285(file, NULL);
return;
}
