vsock/test: verify socket options after setting them

2024-12-05T10:39:34Z

Replace setsockopt() calls with calls to functions that follow setsockopt() with getsockopt() and check that the returned value and its size are the same as have been set. (Except in vsock_perf.) Signed-off-by: Konstantin Shkolnyy Reviewed-by: Stefano Garzarella Signed-off-by: Paolo Abeni

vsock/test: fix parameter types in SO_VM_SOCKETS_* calls

2024-12-05T10:39:33Z

Change parameters of SO_VM_SOCKETS_* to unsigned long long as documented in the vm_sockets.h, because the corresponding kernel code requires them to be at least 64-bit, no matter what architecture. Otherwise they are too small on 32-bit machines.

vsock/test: fix failures due to wrong SO_RCVLOWAT parameter

2024-12-05T10:39:33Z

This happens on 64-bit big-endian machines. SO_RCVLOWAT requires an int parameter. However, instead of int, the test uses unsigned long in one place and size_t in another. Both are 8 bytes long on 64-bit machines. The kernel, having received the 8 bytes, doesn't test for the exact size of the parameter, it only cares that it's >= sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT returns with success and the socket stays with the default SO_RCVLOWAT = 1, which results in vsock_test failures, while vsock_perf doesn't even notice that it's failed to change it.

test/vsock: add ioctl unsent bytes test

2024-08-02T08:20:28Z

Introduce two tests, one for SOCK_STREAM and one for SOCK_SEQPACKET, which use SIOCOUTQ ioctl to check that the number of unsent bytes is zero after delivering a packet. vsock_connect and vsock_accept are no longer static: this is to create more generic tests, allowing code to be reused for SEQPACKET and STREAM.

vsock/test: add '--peer-port' input argument

2024-01-25T01:47:35Z

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.

vsock/test: two tests to check credit update logic

2023-12-15T10:37:35Z

Both tests are almost same, only differs in two 'if' conditions, so implemented in a single function. Tests check, that credit update message is sent: 1) During setting SO_RCVLOWAT value of the socket. 2) When number of 'rx_bytes' become smaller than SO_RCVLOWAT value.

vsock/test: fix SEQPACKET message bounds test

2023-11-23T16:49:16Z

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.
