[PATCH bpf-next 0/3] skmsg: Add the data length in skmsg to SIOCINQ ioctl and rx_queue

[Pengcheng Yang <yangpc@wangsu.com>]

When using skmsg redirect, the msg is queued in psock->ingress_msg,
and the application calling SIOCINQ ioctl will return a readable
length of 0, and we cannot track the data length of ingress_msg from
the ss tool.

In this patch set, we added the data length in ingress_msg to the 
SIOCINQ ioctl and the rx_queue of tcp_diag.

Pengcheng Yang (3):
  skmsg: Calculate the data length in ingress_msg
  tcp: Add the data length in skmsg to SIOCINQ ioctl
  tcp_diag: Add the data length in skmsg to rx_queue
