2023-04-04vsock/test: update expected return valuesArseniy Krasnov1-2/+2
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 <[email protected]> Reviewed-by: Stefano Garzarella <[email protected]> Signed-off-by: Paolo Abeni <[email protected]>

2023-03-30test/vsock: new skbuff appending testArseniy Krasnov1-0/+90
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 <[email protected]> Reviewed-by: Stefano Garzarella <[email protected]> Signed-off-by: Paolo Abeni <[email protected]>

2023-03-16test/vsock: copy to user failure testArseniy Krasnov1-0/+118
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.

2023-01-12test/vsock: add big message testArseniy Krasnov1-0/+69
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.

2023-01-12test/vsock: rework message bounds testArseniy Krasnov5-15/+157
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.

2022-03-18af_vsock: SOCK_SEQPACKET broken buffer testKrasnov Arseniy Vladimirovich1-0/+131
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.

2021-10-15vsock_diag_test: remove free_sock_stat() call in test_no_socketsStefano Garzarella1-2/+0
In `test_no_sockets` we don't expect any sockets, indeed check_no_sockets() prints an error and exits if `sockets` list is not empty, so free_sock_stat() call is unnecessary since it would only be called when the `sockets` list is empty. This was discovered by a strange warning printed by gcc v11.2.1: In file included from ../../include/linux/list.h:7, from vsock_diag_test.c:18: vsock_diag_test.c: In function ‘test_no_sockets’: ../../include/linux/kernel.h:35:45: error: array subscript ‘struct vsock_stat[0]’ is partly outside array bound s of ‘struct list_head[1]’ [-Werror=array-bounds] 35 | const typeof(((type *)0)->member) * __mptr = (ptr); \ | ^~~~~~ ../../include/linux/list.h:352:9: note: in expansion of macro ‘container_of’ 352 | container_of(ptr, type, member) | ^~~~~~~~~~~~ ../../include/linux/list.h:393:9: note: in expansion of macro ‘list_entry’ 393 | list_entry((pos)->member.next, typeof(*(pos)), member) | ^~~~~~~~~~ ../../include/linux/list.h:522:21: note: in expansion of macro ‘list_next_entry’ 522 | n = list_next_entry(pos, member); \ | ^~~~~~~~~~~~~~~ vsock_diag_test.c:325:9: note: in expansion of macro ‘list_for_each_entry_safe’ 325 | list_for_each_entry_safe(st, next, sockets, list) { | ^~~~~~~~~~~~~~~~~~~~~~~~ In file included from vsock_diag_test.c:18: vsock_diag_test.c:333:19: note: while referencing ‘sockets’ 333 | LIST_HEAD(sockets); | ^~~~~~~ ../../include/linux/list.h:23:26: note: in definition of macro ‘LIST_HEAD’ 23 | struct list_head name = LIST_HEAD_INIT(name) It seems related to some compiler optimization and assumption about the empty `sockets` list, since this warning is printed only with -02 or -O3. Also removing `exit(1)` from check_no_sockets() makes the warning disappear since in that case free_sock_stat() can be reached also when the list is not empty.

2020-02-16tools: testing: vsock: Test when server is bound but not listeningSebastien Boeuf1-0/+77
Whenever the server side of vsock is binding to the socket, but not listening yet, we expect the behavior from the client to be identical to what happens when the server is not even started. This new test runs the server side so that it binds to the socket without ever listening to it. The client side will try to connect and should receive an ECONNRESET error. This new test provides a way to validate the previously introduced patch for making sure the server side will always answer with a RST packet in case the client requested a new connection.
