| |
Hi,
I have a network driver that get specific informations from device but I can't envisage the size of the informations. So I do a kmalloc call when data come.
But my problem seems to come from the kmalloc because when I try to send data to user space via an ioctl call I get a segmentation fault.
One solution would be to pass fixed size beetween the both but it isn't the cleaner.
I've heard about copy_to_user method , is it the best way ? Is there a way to create a struct in user space dynamicaly from kernel space ?
thanks for any help ...
