- Previously machine did not handle AnyEvent correctly,
implementation in BaseState was always run
- Changing from ActiveState to ReadyState was bugged,
previously only one of event SubprocessStopped or UdevNotification
caused state change when it is required to wait for both
- Introduced longer timer when waiting for ReadyState during Eject and
ActiveState during Inject, because ndbkit can timeout during Eject and
it is required to complete before next inject can success.
- Added event notification when process is terminated
- Added resourcess classes to handle deletion and notifications

This change introduces new 'Mount' API argument - UNIX_FD for named pipe.
This named pipe is utilized to securely send secret data over D-Bus.
Currently data consists of null-terminated char buffers with username and
password.
Data on receiving side is encapsulated into classes whose role is to:
- keep secret as short-lived as possible
- erase secret from memory when it's not needed
- pass secrets (and format them) to another secure container with above
capabilities
New classes:
- Credentials: is a class encapsulating login and password. It zeroes them
at destruction.
- CredentialProvider: contains Credentials, specifies SecureBuffer, allows
to store credentials in SecureBuffer
- SecureBuffer: char vector which zeroes itself at destruction,
used to provision secret data
- VolatileFile: class creating temporary file with 'owner-only' permissions
in /tmp; at destruction overwrites it's contents with '*' and removes it
New behavior:
- when UNIX_FD is provided over D-Bus it's treated as open unix pipe. Data
is read from this pipe and stored securely into CredentialsProvider
- credentials are stored in applications inside CredentialsProvider object,
encapsulated by unique_ptr for as long as it's needed
- strings containing secrets are zeroed immediately after use
- VolatileFile is used to securely pass credentials to nbdkit curl plugin
instead of command line parameters.
Tested:
Manual and automated tests on WilsonCity platform:
- positive and negative tests for authentication on both CIFS and HTTPS
resources
- error injection (ill-formed data transfered over pipe, pipe broken etc.)

This change introduces integration of virtual-media application with
NBDKit. NBDKit is used here to connect to externally provided image on web
and expose NBD device internally in BMC for NBD subsystem (already
implemented in Proxy mode) to use.
'Mount' D-Bus call accepts 's imgUrl' and 'b rw'. Based on 's imgUrl'
prefix (https:// or smb://) proper mount type is attempted. 'b rw'
determines Read-Only mode for both USB Gadget and NBD stack.
When 'Mount' is called, virtual-media parses arguments, determines mounting
options and attempts to mount external share.
For SMB protocol native CIFS Linux module is used:
1) mount(8) call is used to mound provided CIFS share
2) NBDKit loads file on mounted filesystem and exposes NBD Server on
internal unix socket
3) Pre-existing code takes care of mouting gadget automatically
(connecting socket to /dev/nbdX and then /dev/nbdX to USB Gadget)
For HTTPS protocol provisioning is performed by NBDKit:
1) NBDKit connects to provided resource and exposes NBD Server on internal
unix socket
2) Pre-existing code takes care of mouting gadget automatically
(connecting socket to /dev/nbdX and then /dev/nbdX to USB Gadget)
Tested:
Manual and automated tests on WilsonCity platform:
- mounting and unmounting images over CIFS and HTTPS (single, multiple
at the same time etc)
- positive and negative tests for D-Bus calls
- ensuring proper information is exposed on D-Bus
