event_monitor: Add new crate for event reporting This crate exposes the abililty for the VMM to set a file that events should be written to. The event!() macro provides an interface to report those events allowing the specification of an event source, an event type and optional extra data. This will be written to the provided file descriptor as JSON data. Signed-off-by: Rob Bradford <robert.bradford@intel.com> 2021-02-17 11:16:00 +00:00			`[package]`

build: migrate to Rust 2021 edition Rust 2021 edition has a few improvements over the 2018 edition. Migrate the project to 2021 edition by following recommended migration steps. Luckily, the code itself doesn't require fixing. Bump MSRV to 1.56 as it is required by the 2021 edition. Also fix the clap build dependency to make Cloud Hypervisor build again.

event_monitor: refactor the implementation to support concurrent access This patch modifies `event_monitor` to ensure that concurrent access to `event_log` from multiple threads is safe. Previously, the `event_log` function would acquire a reference to the event log file and write to it without doing any synchronization, which made it prone to data races. This issue likely went under the radar because the relevant `SAFETY` comment on the unsafe block was incomplete. The new implementation spawns a dedicated thread named `event-monitor` solely for writing to the file. It uses the MPMC channel exposed by `flume` to pass messages to the `event-monitor` thread. Since `flume::Sender<T>` implements `Sync`, it is safe for multiple threads to share it and send messages to the `event-monitor` thread. This is not possible with `std::sync::mpsc::Sender<T>` since it's `!Sync`, meaning it is not safe for it to be shared between different threads. The `event_monitor::set_monitor` function now only initializes the required global state and returns an instance of the `Monitor` struct. This decouples the actual logging logic from the `event_monitor` crate. The `event-monitor` thread is then spawned by the `vmm` crate.
