+qemu-bridge-helper failure but qemu not exit
+
+When qemu-bridge-helper run failed, its parent process qemu is still alive.
+This is my command line:
+
+qemu-system-x86_64 -curses -enable-kvm -cpu host -smp 4 -m 4096 \
+  -vnc :1 \
+  -kernel /data/xugang_vms/boot/vmlinuz \
+  -initrd /data/xugang_vms/boot/initram \
+  -append 'module_blacklist=drm,evbug net.ifnames=0 biosdevname=0 ROOTDEV=rootfs' \
+  -drive file=/data/xugang_vms/instances/vn7/rootfs.img,format=qcow2,if=virtio \
+  -monitor unix:/data/xugang_vms/var/monitor/vn7.sock,server,nowait \
+  -netdev bridge,br=vmbr99,helper="/root/bridgehelper --ns=kvm_1 ",id=n1 -device virtio-net,netdev=n1,mac=92:99:98:76:01:07
+
+"/root/bridgehelper" is self defined helper binary by me. But after bridge-helper exited with failure(not send fd to qemu process yet), the linux vm's console will be messed up. I checked the qemu source code(at net/tap.c) and found following snip:
+
+===>
+do {
+            fd = recv_fd(sv[0]);
+        } while (fd == -1 && errno == EINTR);
+        saved_errno = errno;
+
+        close(sv[0]);
+
+        while (waitpid(pid, &status, 0) != pid) {
+            /* loop */
+        }
+<=========
+
+why recv_fd will infinitely wait for recv? Maybe it shall waitpid and then recv_fd ?
+
+
+This is an automated cleanup. This bug report has been moved to QEMU's
+new bug tracker on gitlab.com and thus gets marked as 'expired' now.
+Please continue with the discussion here:
