Date: Sun, 1 Aug 2021 16:02:18 +0800	[thread overview]
Message-ID: <CANTwqXD1zfeyjXD+eyjzSaKBuT5k-4HQJ36AR4u3eUVzeO8b6Q@mail.gmail.com> (raw)

Hi,
I found there leaves a dangling pointer urb in function
usbnet_start_xmit in v5.14-rc3,
1386:  entry->urb = urb;
1451:  usb_put_urb(urb);
1454:  goto deferred;

1492:   deferred:
1494:         return NETDEV_TX_OK;

left a pointer in entry->urb,  I'm not sure whether it cound be used
in usbnet_bh

Any feedback would be appreciated, thanks :)


Best wishes,
Nil Yi
