Commit Message

fix(vsock): set guest-initiated connections to non-blocking

In guest-initiated connections, the Unix stream socket was created in
blocking mode. This caused the `uds_vsock` worker to block indefinitely
when reading from the socket if the RX queue had available buffers but
the host had not sent enough data to fill them.

The test is also updated to use multiple buffers in the RX queue to
reproduce and verify the fix.
