Hi all:
the memory allocated by malloc in user space is virtually contiguous .. but it's not necessary logically contiguous CMIIW
does this means that it's not correct to use arithmetic pointer operations on a user space memory ..
i.e is this correct:
copy_from_user(kernel_buf1, user_buf, size1);
copy_from_user(kernel_buf2, user_buf + size1, size2);
and in case it wasn't .. is there any way to do it other than copying all user_buf to kernel memory first .. kernel_buf1,2 are pre-allocated so i wanna avoid kmallocing memory in kernel space then copying it to kernel_buf1,2
thanks in advance
