This is a regression test for firecracker-microvm#1444 Signed-off-by: Ioana Chirca <[email protected]>
Validate that the RX queue won't freeze under high stateless ingress traffic when encountering bottlenecks on the tap. Signed-off-by: Serban Iorga <[email protected]>
Under heavy ingress traffic we might end up in a situation where the tap device is full, but the rx.deferred_frame flag is not set. Beeing in this state the firecracker RX queue becomes effectively blocked. The tap won't issue any new event because of the EPOLLET flag, while any rate limiter or RX queue event won't do any processing because the rx.deferred_frame flag is not set. We need to make sure we set the rx.deferred_frame flag on all the paths that leave unprocessed frames in the tap.

Add a new parameter to devtool that fixes permissions for the build directory (the one that can get modified by the container). This way unprivileged users can regain rights (i.e delete build session) when devtool dies in the middle of a privileged session. Signed-off-by: Diana Popa <[email protected]>
