Change the default behavior of mount/umount dbus calls from blocking to
unblocking ones.
Once mount/unmount is triggered, appropriate action is running in the
background moving handling of operation result to async event. At the
end of processing dbus completion signal is sent to client with uint
value of operation status (identical with errno code).
Tested:
Manual scheduling of mount and unmount operations with monitoring dbus
communication of virtual-media service - matching api calls with
completion signal.

Due to requirements from community, new projects have to be built with
meson.
To unify with other projects some additional warnings has been enabled,
so appropriate code updates has been implemented.
This commit makes both meson and CMake available to simplyfy transition
in openbmc. CMake support will be removed after switching to meson in
openbmc will be accepted.
Tested:
Compiled and smoke tested.

* Force udev change event on init
This change provides temporary workaround for HSD HSD18020136609 ("Can not mount image using Virtual media and CIFS protocol"). When in initial state, additional udev change event is triggered for all NBD devices, which prevents from disconnection on first mount attempt after reboot. The actual issue is a regression, introduced after kernel update from 5.10.67 to 5.14.11. The exact source in kernel is yet to be located; after that an actual fix shall be provided and this change will be reverted.
Abstracts echoToFile to a separate class, that may be used by other classes through inheritance. This way, writing to udev files can be handled by different object than UsbGadget.
Tested:
Successful mounts after reboot for all supported methods (Proxy, Legacy HTTPS, Legacy CIFS).

In the mechanism of passing the password to client application a file
with password is used. Until now, the file has been created with use of
unsecure tmpnam function, which can be a subject of TOCTOU vulnerability.
Changing tmpnam to mkstemp required some changes in the
flow (std::fstream can't reuse file descriptor of opened file,
appropriate file permissions are set by mkstemp).
Tested:
Manually. Password is passed to nbdkit, temporary file permissions are the same as
before.

Socket files needed to serve virtual media devices are created in /tmp
directory which is temporary tmpfs mount. All temporary directories are
subject of systemd's systemd-tmpfiles-clean.service which cleanes up
them basing on age.
Systemd-tmpfiles-clean uses tmpfiles.d entries to manage all temporary
directories. This change moves creation of VM socket directory to
tmpfiles.d - appropriate config has been added for Virtual Media. The
entry will create socket directory without Age limitation.
Socket location is moved from /tmp to /run. Is it more
appropriate place where all daemons should have it's working files
located.
Tested:
Manually mounting proxy and legacy cifs/https share, running
systemd-tmpfiles-clean.service does not render any problems.

According to security guidelines, files created by service must be
limited to the narrowest set of permissions required. This must be also
true for 3rd party files used by Virtual Media.
- For all regular files and directories created by service umask is
used.
- For sockets, permissions are limited by permissions of parent
directory. For full reference see man unix(7). Below the most important
fragment:
"In the Linux implementation, sockets which are visible in the
filesystem honor the permissions of the directory they are in. Their
owner, group and their permissions can be changed. Creation of a new
socket will fail if the process does not have write and search (execute)
permission on the directory the socket is created in. Connecting to the
socket object requires read/write permission. This behavior differs from
many BSD-derived systems which ignore permissions for UNIX domain
sockets. Portable programs should not rely on this feature for
security."

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.)

Previously implemented error handling for Mount checks only if mounting was
successful and returns boolean with the result.
Following change introduces optional error to existing ReadyState
(a.k.a. "idle state"). If state machine enters ReadyState with error it is
stored into ReadyState field with std::errc and std::string message.
In the case of mount failure with such error information stored, Mount
returns graceful D-Bus error reply with specific error code.
Tested:
Manual and automated tests on WilsonCity platform:
- negative tests for invalid network share, unauthorized share access,
error injection (renaming expected unix socket names 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
