tools/virtio: check mmap return value in vringh_test

2026-07-24T13:51:34+00:00

[ Upstream commit ec6177dfe98b9be1c3ede6c0dfe4394ea2a76959 ] In parallel_test(), the return values of mmap() for both host_map and guest_map are not checked against MAP_FAILED. If mmap() fails, the subsequent code will dereference the invalid pointer, leading to a segmentation fault. Add MAP_FAILED checks after both mmap() calls, using err() to report the error and exit, consistent with the existing error handling style in this file (e.g., the open() call on line 149).

[ Upstream commit c262f75cb6bb5a63828e72ce3b8fe808e5029479 ] The virtio_device vqs_list spinlocks must be initialized before use to prevent functions that manipulate the device virtualqueues, such as vring_new_virtqueue(), from blocking indefinitely.
