Hi,
I tried to call the following code in a kernel module:
error = do_path_lookup(AT_FDCWD, "/etc/profile.d/glib2.csh",
LOOKUP_PARENT, &nd);
I exported the function do_path_lookup() using
"EXPORT_SYMBOL_GPL(do_path_lookup);"
But do_path_lookup() caused the "general protection fault: 0000 [#1]"
kernel error.
I thought it could be the problem of protection error, so I used the
following codes to enclose the code that calls do_path_lookup(), but
still got the same error.
fs = get_fs (); /*
save previous value */
set_fs (KERNEL_DS); /*
use kernel limit */
......
set_fs(fs);
Any idea on this?
Thanks a lot!
