Subject: [PATCH v10 17/18] vsock_test: add SOCK_SEQPACKET tests
Date: Thu, 20 May 2021 22:19:50 +0300 [thread overview]
Message-ID: <20210520191953.1272798-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210520191357.1270473-1-arseny.krasnov@kaspersky.com>
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>
---
v9 -> v10:
1) Commit message updated.
2) Add second test for message bounds.
