USB device attach events are missing for a specific device

Issue description

USB device attach events are missing for a specific device.

I have a USB camera that has two modes. In the first (startup) mode, bootloader mode, it is a USB2 device. To use the camera the camera's API loads a firmware into it while it is in the bootloader mode, then the camera restarts. After restarting the camera becomes either a USB2 device or a USB3 device (depending on a switch; the default is USB3) with the same vendor ID but a different product ID. When shut down, the camera reboots back into the USB2 bootloader mode.

Running the device's software in my host PC works as expected. Running the same software inside my LXD container fails to find the running-mode device. Debugging using libusb has shown that the specific event indicating the new device has been attached to the USB bus is not received by the application, even though all other device attach/remove events are.

I have added a device to my container that covers both modes by specifying only the vendor ID:

$ lxc config device add my_container oakd usb vendorid=03e7

The device shows up correctly inside the container using this device. Both the bootloader mode device and the running-mode device appear correctly in /dev/bus/usb, and with the correct permissions thanks to a udev rule, SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666". Here's a sample showing the running-mode device inside the container:

/dev/bus/usb:
total 0
drwxr-xr-x 2 root root 40 Aug 13 07:02 001
drwxr-xr-x 2 root root 40 Aug 20 09:24 003
drwxr-xr-x 2 root root 60 Aug 20 09:24 004

/dev/bus/usb/001:
total 0

/dev/bus/usb/003:
total 0

/dev/bus/usb/004:
total 0
crw-rw-rw- 1 root root 189, 431 Aug 20 09:24 048

When the device's software is run inside the container, it correctly initialises the device from bootloader mode to running-mode, but then cannot find the device as it does not receive the notification about the running-mode device attaching to the USB bus.

Here's what it looks like in dmesg when the software runs:

[3233363.346779] usb 3-2.3: USB disconnect, device number 88
[3233363.641018] usb 4-2.3: new SuperSpeed Gen 1 USB device number 48 using xhci_hcd

Device 88 on the USB2 bus is the bootloader mode device, which disconnects and is replaced by the running-mode device number 48 on the USB3 bus. When the software fails to respond to the camera, after a timeout it reboots back into bootloader mode, giving device 89 on the USB2 bus.

Running the application with LIBUSB_DEBUG=4 is what told us that the attachment notification event is not received by the application. The following events are received by the application.

The removal of the bootloader-mode device when it reboots:

[ 1.445999] [0000164e] libusb: debug [linux_netlink_read_message] netlink hotplug found device busnum: 3, devaddr: 30, sys_name: 3-2, removed: yes

The appearance of the bootloader-mode device after the running-mode device gives up and reboots:

[10.156069] [0000164e] libusb: debug [linux_netlink_read_message] netlink hotplug found device busnum: 3, devaddr: 31, sys_name: 3-2, removed: no

The removal of the running-mode device when it gives up and reboots (note that this happens after the above line):

[10.467585] [0000164e] libusb: debug [linux_netlink_read_message] netlink hotplug found device busnum: 4, devaddr: 19, sys_name: 4-2, removed: yes

Notably absent from the debug output in the container is the event for the running-mode device appearing, even though the device node in /dev/bus/usb is created properly, has the correct permissions, etc., and even though it gets an event for the device's removal from the USB bus. This pattern appears to be also visible in the /var/log/lxd/lxd.log file.

Running on the host, the debug output does contain an event for the running-mode device appearance. It is only within the LXD container that this event is missing.

Running the software with the device using USB2 in its running mode correctly shows a USB2 device in /dev/bus/usb but the attach event still does not appear in the application.

I have tried adding a cgroup LXC rule directly:

$ lxc config set oakd_test raw.lxc="lxc.cgroup.devices.allow = c 189:* rwm"

But this made no difference to the behaviour, and I'm guessing that it's added already anyway by the LXD device config.

See this issue on the DepthAI repository for where this bug was discovered and our debugging process to date.

Steps to reproduce

You will need an OAK-D camera, or possibly some similar device that reboots into a separate mode to be used, to reproduce this issue.

  1. Create an LXD container with Ubuntu 20.04 
    lxc launch ubuntu:20.04 my_container
  2. Enter the container 
    lxc exec my_container --user 1000 --group 1000 -- bash --login
  3. In the container, set up the udev rule for DepthAI 
    echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | sudo tee /etc/udev/rules.d/80-movidius.rules
sudo udevadm control --reload-rules && sudo udevadm trigger
  4. On the host, add the USB device to the container: 
    lxc config device add my_container oakd usb vendorid=03e7
  5. Plug in the OAK-D
  6. In the container, execute the depthai_demo.py demonstration application
  7. Observe that the application finds the OAK-D in its bootloader mode, but fails to find the device after it reboots.

@brauner this is going to be one for you as you wrote all that fun uevent handling logic!

stgraber avatar Aug 23 '21 19:08 stgraber

@brauner reminder to look into this when you're back

stgraber avatar Sep 10 '21 04:09 stgraber

@stgraber is this still on @brauner's TODO list?

zyga avatar Nov 01 '21 12:11 zyga

@gbiggs, I sent a tentative fix for this but can you please show me the output of udevadm monitor debug on the host with all the events that you expect to see and then udevadm monitor debug from inside the container with the received events.

brauner avatar Nov 01 '21 13:11 brauner

Sorry for being slow to respond to this issue and check if the fix works. I've been snowed under for the past couple of months. I'll have time over the holidays to move this forward.

Is this still an issue then?

I need more insight into what's actually sent over the wire. Can you compile and run the following program and then show me the uevents associated with that camera, please:

#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <asm/types.h>
#include <linux/netlink.h>

int fd_uevent = -EBADF;

{
	struct sockaddr_nl local;
	socklen_t socklen;
	int sndbuf = 32768;
	int rcvbuf = 32768;

	fd_uevent = socket(AF_NETLINK, SOCK_RAW | SOCK_CLOEXEC, NETLINK_KOBJECT_UEVENT);
	if (fd_uevent < 0)
		return -1;

	if (setsockopt(fd_uevent, SOL_SOCKET, SO_RCVBUF, &rcvbuf,sizeof(rcvbuf)) < 0)

	memset(&local, 0, sizeof(local));
	local.nl_family = AF_NETLINK;
	local.nl_groups = -1;
	local.nl_pid = getpid();

	socklen = sizeof(local);
	if (getsockname(fd_uevent, (struct sockaddr*)&local, &socklen) < 0)
		return -1;

	if (socklen != sizeof(local))

	do {
		ret = write(fd, buf, count);
	} while (ret < 0 && errno == EINTR);

	return ret;
}

int main(int argc, char *argv[])
{
	int ret;
	char buf[UEVENT_BUFFER_SIZE];
	char *buf_ptr;

	fd_uevent = uevent_socket_open();
	if (fd_uevent < 0) {

		exit(EXIT_FAILURE);
	}

	ret = EXIT_SUCCESS;

			buf_ptr += 40;
			r -= 40;
			write_nointr(STDOUT_FILENO, "libudev: ", sizeof("libudev: ") - 1);
		} else {
			write_nointr(STDOUT_FILENO, "udev: ", sizeof("udev: ") - 1);
		}

		if (r != w) {
			ret = EXIT_FAILURE;
			goto on_error;
		}
		write_nointr(STDOUT_FILENO, "\n", 1);
	}

	close(fd_uevent);
	exit(ret);
}
