vsock/test: update expected return values

2023-04-04T10:46:24Z

This updates expected return values for invalid buffer test. Now such values are returned from transport, not from af_vsock.c. Signed-off-by: Arseniy Krasnov Reviewed-by: Stefano Garzarella Signed-off-by: Paolo Abeni

test/vsock: new skbuff appending test

2023-03-30T08:47:48Z

This adds test which checks case when data of newly received skbuff is appended to the last skbuff in the socket's queue. It looks like simple test with 'send()' and 'recv()', but internally it triggers logic which appends one received skbuff to another. Test checks that this feature works correctly. This test is actual only for virtio transport. Signed-off-by: Arseniy Krasnov Reviewed-by: Stefano Garzarella Signed-off-by: Paolo Abeni

test/vsock: copy to user failure test

2023-03-16T17:28:23Z

This adds SOCK_STREAM and SOCK_SEQPACKET tests for invalid buffer case. It tries to read data to NULL buffer (data already presents in socket's queue), then uses valid buffer. For SOCK_STREAM second read must return data, because skbuff is not dropped, but for SOCK_SEQPACKET skbuff will be dropped by kernel, and 'recv()' will return EAGAIN.

test/vsock: vsock_perf utility

This adds utility to check vsock rx/tx performance. Usage as sender: ./vsock_perf --sender --port --bytes Usage as receiver: ./vsock_perf --port --rcvlowat Signed-off-by: Arseniy Krasnov Reviewed-by: Stefano Garzarella Signed-off-by: Paolo Abeni

test/vsock: add big message test

2023-01-12T11:53:54Z

This adds test for sending message, bigger than peer's buffer size. For SOCK_SEQPACKET socket it must fail, as this type of socket has message size limit. Signed-off-by: Arseniy Krasnov Reviewed-by: Stefano Garzarella Signed-off-by: Paolo Abeni

test/vsock: rework message bounds test

2023-01-12T11:53:54Z

This updates message bound test making it more complex. Instead of sending 1 bytes messages with one MSG_EOR bit, it sends messages of random length(one half of messages are smaller than page size, second half are bigger) with random number of MSG_EOR bits set. Receiver also don't know total number of messages. Signed-off-by: Arseniy Krasnov Reviewed-by: Stefano Garzarella Signed-off-by: Paolo Abeni

vsock_test: POLLIN + SO_RCVLOWAT test

af_vsock: SOCK_SEQPACKET broken buffer test

2022-03-18T15:13:19Z

Add test where sender sends two message, each with own data pattern. Reader tries to read first to broken buffer: it has three pages size, but middle page is unmapped. Then, reader tries to read second message to valid buffer. Test checks, that uncopied part of first message was dropped and thus not copied as part of second message.
