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.

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.

vsock/test: track bytes in sk_buff merging test for SOCK_SEQPACKET

2023-09-17T16:42:37+00:00

The test was a bit complicated to read.
Added variables to keep track of the bytes read and to be read
in each step. Also some comments.

The test is unchanged.

vsock/test: use send_buf() in vsock_test.c

2023-09-17T16:42:37+00:00

We have a very common pattern used in vsock_test that we can
now replace with the new send_buf().

This allows us to reuse the code we already had to check the
actual return value and wait for all the bytes to be sent with
an appropriate timeout.

test/vsock: shutdowned socket test

2023-09-14T06:19:55+00:00

This adds two tests for 'shutdown()' call. It checks that SIGPIPE is
sent when MSG_NOSIGNAL is not set and vice versa. Both flags SHUT_WR
and SHUT_RD are tested.
