test/vsock: vsock_perf utility This adds utility to check vsock rx/tx performance.

test/vsock: io_uring rx/tx tests This adds set of tests which use io_uring for rx/tx. This test suite is implemented as separated util like 'vsock_test' and has the same set of input arguments as 'vsock_test'. These tests only cover cases of data transmission (no connect/bind/accept etc).

test/vsock: MSG_ZEROCOPY flag tests This adds three tests for MSG_ZEROCOPY feature: 1) SOCK_STREAM tx with different buffers. 2) SOCK_SEQPACKET tx with different buffers. 3) SOCK_STREAM test to read empty error queue of the socket. Patch also works as preparation for the next patches for tools in this patchset: vsock_perf and vsock_uring_test: 1) Adds several new functions to util.c - they will be also used by vsock_uring_test. 2) Adds two new functions for MSG_ZEROCOPY handling to a new source file - such source will be shared between vsock_test, vsock_perf and vsock_uring_test, thus avoiding code copy-pasting.

vsock/test: Add test for null ptr deref when transport changes Add a new test to ensure that when the transport changes a null pointer dereference does not occur. The bug was reported upstream [1] and fixed with commit 2cb7c756f605 ("vsock/virtio: discard packets if the transport changes"). KASAN: null-ptr-deref in range [0x0000000000000060-0x0000000000000067] CPU: 2 UID: 0 PID: 463 Comm: kworker/2:3 Not tainted Workqueue: vsock-loopback vsock_loopback_work RIP: 0010:vsock_stream_has_data+0x44/0x70 Call Trace: virtio_transport_do_close+0x68/0x1a0 virtio_transport_recv_pkt+0x1045/0x2ae4 vsock_loopback_work+0x27d/0x3f0 process_one_work+0x846/0x1420 worker_thread+0x5b3/0xf80 kthread+0x35a/0x700 ret_from_fork+0x2d/0x70 ret_from_fork_asm+0x1a/0x30 Note that this test may not fail in a kernel without the fix, but it may hang on the client side if it triggers a kernel oops. This works by creating a socket, trying to connect to a server, and then executing a second connect operation on the same socket but to a different CID (0). This triggers a transport change. If the connect operation is interrupted by a signal, this could cause a null-ptr-deref. Since this bug is non-deterministic, we need to try several times. It is reasonable to assume that the bug will show up within the timeout period. If there is a G2H transport loaded in the system, the bug is not triggered and this test will always pass. This is because `vsock_assign_transport`, when using CID 0, like in this case, sets vsk->transport to `transport_g2h` that is not NULL if a G2H transport is available.
