[Bug 1245255] Re: IO-Error when trying to change the master password of a self encrypting ssd

[Seth Arnold]

I believe the Linux kernel's default configuration is to filter out
these commands (so your webserver doesn't set a password for you :) --
see e.g.
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/ata
/libata-scsi.c?id=HEAD#n3043

(Though I'm a bit confused, that's in the libata code, and I don't see
libata loaded on my laptop...)

Try adding libata.allow_tpm=1 to the kernel command line via's grub
edit-command option, and see if this changes the situation.

Thanks

Title:
  IO-Error when trying to change the master password of a self
  encrypting ssd

Status in “hdparm” package in Ubuntu:
  Incomplete

Bug description:
   I tried to set the master password on my self encrypting Samsung SSD
  840 Pro in a Dell Latitude 6400 ATG laptop (Bios Version: A34), german
  keyboard via

  sudo hdparm --user-master m --security-set-pass "$( printf
  'testmasterpassword' | tr '1234567890qwertzuiopasdfghjklyxcvbnm'
  '\2-\11\20\21\26\27\30\31\40-\45\60-\70\104-\107\110\111\120')"
  /dev/sda

  this gives me the following error:

  security_password=" 1 P01 %011$2" /dev/sda: Issuing SECURITY_SET_PASS
  command, password=" 1 P01 %011$2", user=master, mode=high
  SECURITY_SET_PASS: Input/output error

  Any idea, whats wrong here? Is there a workaround?
