[dm-crypt] truecrypt - what's the real story behind it?

["U.Mutlu" <for-gmane@mutluit.com>]

Hi,
the cryptsetup tool supports besides plain and luks, also loopaes and truecrypt.
I now compiled truecrypt-7.1a, and it looks not bad.
I wonder why some people say truecrypt is no more secure.
Which part or method of truecrypt is allegedly broken? Can't be fixed?
And: is full truecrypt functionality integrated in cryptsetup tool? I mean the 
create-options below.

Here's a manually done "create"-session with the available options:

# truecrypt -c

Enter volume size (sizeK/size[M]/sizeG): : 250M

Encryption algorithm:
  1) AES
  2) Serpent
  3) Twofish
  4) AES-Twofish
  5) AES-Twofish-Serpent

  8) Twofish-Serpent
Select [1]: 3
