RE: Whate kind of kernel errors cause an Segmentation Fault

Well he asked what kind of kernel error causes segfault.
If I am not wrong returning EFAULT, e.g. from driver causes
the kernel to send signal 11 (SIGSEGV) to the application
which has default signal handler that causes the application
to crash.

K.D.

No segmentation fault is sent as signal 11 it's not a return value.

Happens when the program uses memory it dose not own.
