[PATCH v2] tcp: Store the owner connections for flags frames
by Yumei Huang 11 Sep '25

11 Sep '25

There is an issue reported by Volker Diels-Grabsch and Boleyn Su. A segmentation fault occurs when executing the following command: (sleep 0.1; ssh -p 22000 127.0.0.1) & passt -f -t 22000:22 It's caused by commit 78da088f7bab ("tcp: unify payload and flags l2 frames array"). Fix it by storing the owner connections of flags frames into tcp_frame_conns[] array.

[PATCH] Send an initial ARP request to resolve the guest IP address
by Volker Diels-Grabsch 10 Sep '25

10 Sep '25

When restarting passt while QEMU keeps running with a configured "reconnect-ms" setting, the port forwardings will stop working until the guest sends some outgoing network traffic. Reason: Although QEMU reconnects successfully to the unix domain socket of the new passt process, that one no longer knows the guest's MAC address and uses instead a broadcast MAC address. However, this is ignored by the guest, at least if the guest runs Linux. Only after the guest sends some network package on its own initiative, passt will know the MAC address and will be able to establish forwarded connections. This change fixes this issue by sending an ARP request to resolve the guest's MAC address via its IP address, which we do know, right after the unix domain socket (re)connection. The only case where the IP is "wrong" would be if the configuration changed, and/or on the very first start right after qemu started. But in those cases, we just wouldn't get an ARP response, and can't do anything until we receive the guest's DHCP request - just as before. In other words, in the worst case an ARP request would be harmless.

[PATCH] Fix segfault on TCP connection before first passt socket connection
by Volker Diels-Grabsch 10 Sep '25

10 Sep '25

This issue can be reproduced by running passt with TCP forwarding and connecting to that TCP port before the first client (e.g. QEMU) connects to the passt socket. Example: (sleep 0.1; ssh -p 22000 127.0.0.1) & passt -f -t 22000:22 Although this commit likely doesn't fix the root cause of this issue, it does reliably fix the segfault. --- tcp_buf.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/tcp_buf.c b/tcp_buf.c index bc898de..1a06f15 100644 --- a/tcp_buf.c +++ b/tcp_buf.c @@ -120,6 +120,9 @@ static void tcp_revert_seq(const struct ctx *c, struct tcp_tap_conn **conns, uint32_t seq = ntohl(th->seq); uint32_t peek_offset; + if (conn == NULL) + continue; + if (SEQ_LE(conn->seq_to_tap, seq)) continue; -- 2.47.3

[PATCH 0/3] This series contains fixes and improvements to the vhost-user implementation
by Laurent Vivier 09 Sep '25

09 Sep '25

The first patch fixes a protocol compliance issue where VHOST_USER_GET_QUEUE_NUM was incorrectly returning the number of virtqueues instead of queue pairs. The vhost-user specification clearly states this should return the maximum number of queues supported by the backend. Since each queue consists of an RX/TX pair, the correct value is VHOST_USER_MAX_VQS / 2. This patch also renames the constant to better reflect its meaning. The second and third patches address virtqueue handling in the UDP and TCP receive paths. These changes pass the virtqueue pointer explicitly to the receive functions, enabling proper queue selection for future multiqueue support. This ensures packets are processed on the same virtqueue as the caller. These changes lay the groundwork for full multiqueue support while fixing existing protocol compliance issues.
