From 646c5478c04297485e3e045cd8969d2ae7642004 Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Mon, 26 Sep 2016 11:08:21 +0300 Subject: record/replay: add network support This patch adds support of recording and replaying network packets in irount rr mode. Record and replay for network interactions is performed with the network filter. Each backend must have its own instance of the replay filter as follows: -netdev user,id=net1 -device rtl8139,netdev=net1 -object filter-replay,id=replay,netdev=net1 Replay network filter is used to record and replay network packets. While recording the virtual machine this filter puts all packets coming from the outer world into the log. In replay mode packets from the log are injected into the network device. All interactions with network backend in replay mode are disabled. v5 changes: - using iov_to_buf function instead of loop Signed-off-by: Pavel Dovgalyuk Signed-off-by: Jason Wang --- vl.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'vl.c') diff --git a/vl.c b/vl.c index d77dd862f9..a23de18fa9 100644 --- a/vl.c +++ b/vl.c @@ -2859,7 +2859,8 @@ static bool object_create_initial(const char *type) g_str_equal(type, "filter-mirror") || g_str_equal(type, "filter-redirector") || g_str_equal(type, "colo-compare") || - g_str_equal(type, "filter-rewriter")) { + g_str_equal(type, "filter-rewriter") || + g_str_equal(type, "filter-replay")) { return false; } -- cgit 1.4.1
