Lyrics

[Verse 1]
Deep inside the kernel's binary maze
Objdump reveals what compilation creates
No execution needed, just forensic sight
Disassembling opcodes in the static light
Symbol tables whisper secrets of the core
Functions mapped like territories to explore

[Chorus]
nm shows the names, objdump shows the flow
Static analysis lets the kernel's secrets grow
Text and data sections, BSS unmarked space
Read the machine code without the runtime race
Symbols tell stories, addresses align
Kernel archaeology, one instruction at a time

[Verse 2]
Dash lowercase t for text section scan
Uppercase T means global, part of the plan
Undefined symbols marked with capital U
Weak references lowercase w will show you
Debug info embedded if the flags were set
Dwarf format dancing through the object net

[Chorus]
nm shows the names, objdump shows the flow
Static analysis lets the kernel's secrets grow
Text and data sections, BSS unmarked space
Read the machine code without the runtime race
Symbols tell stories, addresses align
Kernel archaeology, one instruction at a time

[Bridge]
Hexdump raw bytes when assembly's not enough
Cross-reference symbols when the linking gets rough
Virtual addresses mapped to physical frames
Export tables linking all the kernel's claims

[Verse 3]
Dash capital S shows source interleaved
Assembly mixed with C as originally conceived
Jump targets labeled, call graphs traced
Function boundaries clearly marked and spaced
No runtime overhead, no system calls
Just pure examination of the kernel's walls

[Chorus]
nm shows the names, objdump shows the flow
Static analysis lets the kernel's secrets grow
Text and data sections, BSS unmarked space
Read the machine code without the runtime race
Symbols tell stories, addresses align
Kernel archaeology, one instruction at a time

[Outro]
Before you boot, before the first syscall
Static tools reveal the kernel's protocol
Every byte examined, every symbol known
The kernel's architecture carved in stone
