vsock/test: print type for SOCK_SEQPACKET

2024-01-26T00:39:21+00:00

SOCK_SEQPACKET is supported for virtio transport, so do not interpret
such type of socket as unknown.

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

2024-01-25T01:47:35+00:00

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

2023-12-15T10:37:35+00:00

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

2023-11-23T16:49:16+00:00

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.

This is a preliminary patch to introduce SOCK_STREAM bind connect test.
vsock_accept() is split into vsock_listen() and vsock_accept().

test/vsock: io_uring rx/tx tests

2023-10-15T12:19:43+00:00

This adds set of tests which use io_uring for rx/tx. This test suite is
implemented as separated util like 'vsock_test' and has the same set of
input arguments as 'vsock_test'. These tests only cover cases of data
transmission (no connect/bind/accept etc).

test/vsock: MSG_ZEROCOPY support for vsock_perf

2023-10-15T12:19:42+00:00

To use this option pass '--zerocopy' parameter:

./vsock_perf --zerocopy --sender  ...

With this option MSG_ZEROCOPY flag will be passed to the 'send()' call.

test/vsock: MSG_ZEROCOPY flag tests

2023-10-15T12:19:42+00:00

This adds three tests for MSG_ZEROCOPY feature:
1) SOCK_STREAM tx with different buffers.
2) SOCK_SEQPACKET tx with different buffers.
3) SOCK_STREAM test to read empty error queue of the socket.

Patch also works as preparation for the next patches for tools in this
patchset: vsock_perf and vsock_uring_test:
1) Adds several new functions to util.c - they will be also used by
   vsock_uring_test.
2) Adds two new functions for MSG_ZEROCOPY handling to a new source
   file - such source will be shared between vsock_test, vsock_perf and
   vsock_uring_test, thus avoiding code copy-pasting.
