Subject: [RFC PATCH v8 17/19] vsock_test: add SOCK_SEQPACKET tests
Date: Tue, 13 Apr 2021 15:46:58 +0300 [thread overview]
Message-ID: <20210413124701.3407363-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210413123954.3396314-1-arseny.krasnov@kaspersky.com>
This adds test of SOCK_SEQPACKET socket: it transfer data and
then tests 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>
---
v7 -> v8:
- Test for MSG_EOR flags now removed.
