Filk Lyrics

I admit it, I'm a nerd.  I sometimes construct `filk

Pf The Packet Filter
####################

To the tune of `Puff, the Magic Dragon <https://en.wikipedia.org/wiki/Puff,_the_Magic_Dragon>`_.

  | Chorus:
  | Pf The Packet Filter lived 'side Layer 3
  | And guarded all the network stack
  | In a land called B S D!
  | 
  | The sysadmins all loved him, that firewall called pf,
  | And bid him watch and N A T
  | And other fancy stuff.
  | 
  | [chorus]
  | 
  | The system had been hardened, in every different way,
  | PaX and N X Stack watched over EIP.
  | Raging worms and DoSes never did any harm,
  | and even the most skilled crackers would simply just give up! Oh,
  | 
  | [chorus]
  | 
  | Code can be proven, mathematically pure;
  | E C C and other things can only go so far.
  | One mid day it happened, the cooling system blew,
  | and pf, that mighty guardian, hit a machine check.
  | The fault handler panic()'d, the system simply stopped.
  | Pf no longer got a chance to get an interrupt!
  | The sysadmins saw "db>" and pondered what to do
  | They typed "reboot", heard a beep, and then saw nothing more. Oh,
  | 
  | [chorus]

NOP Ride
########

To the tune of `Sleigh Ride <https://en.wikipedia.org/wiki/Sleigh_Ride>`_.

  | Just watch those buf-fers fill-a-ling
  | And, OOPS!, over-flow-a-ling too!
  | Such a lovely setup
  | For a NOP sled sneaking by you...
  | O'er net, the shell code's coming,
  | And sploits are calling your code;
  | Such a lovely setup
  | For a NOP sled up to the payload!
  | 
  | Fetch decode, fetch decode, fetch decode, let's go!
  | We've found the payload...
  | We're running some injected elite shell code!
  | Fetch decode, fetch decode, fetch decode, it's fine!
  | Just pay us no mind!
  | We'll spawn a thread,
  | And be out of here in no time...
  | 
  | Your heap is big and full
  | And so curious are we...
  | We scan your allocations
  | Like you would never have let us see...
  | We'll take that FILE before us
  | and snoop a socket() or two...
  | What a lovely setup
  | For a NOP sled together with you!
