By using skb_put we ensure that skb->tail is set correctly. Currently, skb->tail is always zero, which leads to errors, such as the following page fault in rfcomm_recv_frame: BUG: unable to handle page fault for address: ffffed1021de29ff #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page RIP: 0010:rfcomm_run+0x831/0x4040 (net/bluetooth/rfcomm/core.c:1751) Fixes: afd2daa26c7a ("Bluetooth: Add support for virtio transport driver") Signed-off-by: Soenke Huster <soenke.huster@eknoes.de> --- v2: Add Fixes tag drivers/bluetooth/virtio_bt.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
