2021-10-15vsock_diag_test: remove free_sock_stat() call in test_no_socketsStefano Garzarella
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.

2021-06-11vsock_test: add SOCK_SEQPACKET testsArseny Krasnov
Implement two tests of SOCK_SEQPACKET socket: first sends data by several 'write()'s and checks that number of 'read()' were same. Second test checks MSG_TRUNC flag. Cases for connect(), bind(), etc. are not tested, because it is same as for stream socket. Signed-off-by: Arseny Krasnov <arseny.krasnov@kaspersky.com> Signed-off-by: David S.

One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.)

2020-02-16tools: testing: vsock: Test when server is bound but not listeningSebastien Boeuf
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.

2019-12-20vsock_test: wait for the remote to close the connectionStefano Garzarella
Before check if a send returns -EPIPE, we need to make sure the connection is closed. To do that, we use epoll API to wait EPOLLRDHUP or EPOLLHUP events on the socket.
