Secure Modules

sm common code

sm modules are loaded to 0x80B000, then code from that addr is executed.

There is a lot of common code shared between sm: entry, cmd handler, cmd setup, etc

Entry

This is the first code executed in sm. It's located at 0x80B000. It does the following:

• Get random value (stack cookie?)
• call_ctors()
• sm_main()
• call_dtors()
• syscall 1: Unload
• while(1) sleep()
