hi all ,
i followed the link and tried to add a system call in kernel-version 2.6.37 here is the code :
#include<linux/linkage.h> #include<linux/kernel.h> #include<linux/fs.h> //for getname #include<linux/err.h> //for PTR_ERR asmlinkage int sys_hariohm(const char __user *filename) { char *tmp = getname(filename); int fd=PTR_ERR(tmp); if (!IS_ERR(tmp)) { printk("filename %s \n",tmp); putname(tmp); return fd; } else { return 2; } }
which syscall number did you assigned to this syscall? and exactly how do you assign it? NB: your code style doesn't follow the Linux kernel coding standart.... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
