2024-01-25vsock/test: print type for SOCK_SEQPACKETArseniy Krasnov1-0/+2
SOCK_SEQPACKET is supported for virtio transport, so do not interpret such type of socket as unknown.

2024-01-24vsock/test: add '--peer-port' input argumentArseniy Krasnov6-58/+115
Implement port for given CID as input argument instead of using hardcoded value '1234'. This allows to run different test instances on a single CID. Port argument is not required parameter and if it is not set, then default value will be '1234' - thus we preserve previous behaviour.

Both tests are almost same, only differs in two 'if' conditions, so implemented in a single function.

2023-11-23vsock/test: fix SEQPACKET message bounds testArseniy Krasnov1-6/+13
Tune message length calculation to make this test work on machines where 'getpagesize()' returns >32KB. Now maximum message length is not hardcoded (on machines above it was smaller than 'getpagesize()' return value, thus we get negative value and test fails), but calculated at runtime and always bigger than 'getpagesize()' result. Reproduced on aarch64 with 64KB page size.

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.

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.
