It appears it was removed from PW due to 30 days inactivity, when that happens you should resend the patch since it needs to be retested by CI.
diff --git a/drivers/bluetooth/virtio_bt.c b/drivers/bluetooth/virtio_bt.c index 67c21263f9e0..fd281d439505 100644 --- a/drivers/bluetooth/virtio_bt.c +++ b/drivers/bluetooth/virtio_bt.c @@ -219,7 +219,7 @@ static void virtbt_rx_work(struct work_struct *work) if (!skb) return; - skb->len = len; + skb_put(skb, len); virtbt_rx_handle(vbt, skb); if (virtbt_add_inbuf(vbt) < 0)
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) Signed-off-by: Soenke Huster <soenke.huster@eknoes.de> --- drivers/bluetooth/virtio_bt.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
