This patch adds one API function to the QEMU plugin API bool qemu_plugin_read_memory_vaddr(vaddr, GByteArray *, size_t);
The API allows reading memory from an arbitrary guest virtual address, which is useful for many things but the motivating examples are: * Virtual Machine Introspection (VMI) * Accurate and easier execution trace extraction * Debugging and logging tools An example of its use is added to the existing syscalls plugin, which now has an option to hexdump the buf argument to any write(2) syscalls which occur. For v3, fixed a missing '*' in a comment which caused a doc build issue.
