Known issues with current example code: If you using newer kernel(e.g linux 5.11.x) to compile the example code, you may meet following error: 1. syscall.c:83:50: error: ‘ksys_close’ undeclared; 2. cryptosk.c:17:24: error: field ‘sg’ has incomplete type 3. cryptosk.c:143:9: error: implicit declaration of function ‘get_random_bytes’ 4. error: macro "DECLARE_TASKLET" passed 3 arguments, but takes just 2 Solutions/workaround: 1. In syscall.c, replace #include <linux/syscalls.h> with #include <linux/fdtable.h> and replace ksys_close with close_fd if the kernel version >= 5.11. [1][2] 2. Add #include <linux/scatterlist.h> into cryptosk.c 3. Add #include <linux/random.h> into cryptosk.c 4. In bottomhalf.c and example_tasklet.c, replace DECLARE_TASKLET with DECLARE_TASKLET_OLD and dispose third argument(0L).
