Angus Lees dbf77fba10 Trivial rootwrap -> privsep replacement 
This change replaces all uses of rootwrap with a trivial privsep-based
equivalent.  This replacement simply executes commands as the privsep
user *without any additional checks*.

There are 2 reasons why this is a reasonable thing to do:

1. We don't have a good workflow for merging rootwrap filter changes
   into parent projects (nova/cinder) for a loosely-coupled library like
   os-brick.

2. The previous situation was also insecure.  The os-brick.filters
   rootwrap config permitted commands like "dd" and "cp" with any
   arguments, as root.  This would have posed only a mild inconvenience
   to an attacker.  With privsep we can at least (in principle) limit
   the commands to the privsep uid/gid and Linux
   capabilities (CAP_SYS_ADMIN by default with this change).

This change addresses the urgency of (1).   Later refactors will take
greater advantage of privsep to address (2).

Latest Version

Downloads

OpenStack Cinder brick library for managing local volume attaches

Features

  • Discovery of volumes being attached to a host for many transport protocols.
  • Removal of volumes from a host.

Hacking

Hacking on brick requires python-gdbm (for Debian derived distributions), Python 2.7 and Python 3.4. A recent tox is required, as is a recent virtualenv (13.1.0 or newer).

If "tox -e py34" fails with the error "db type could not be determined", remove the .testrepository/ directory and then run "tox -e py34".
