Subject: [RFC PATCH 0/6] hv_sock: Hardening changes

Miscellaneous changes to "harden" the hv_sock driver and enable it
in isolated guests.  The diff in ring_buffer.c, hyperv.h is due to
a consequent refactoring/code elimination (patch #6).

Applies to v5.18-rc2.

Thanks,
  Andrea

Andrea Parri (Microsoft) (6):
  hv_sock: Check hv_pkt_iter_first_raw()'s return value
  hv_sock: Copy packets sent by Hyper-V out of the ring buffer
  hv_sock: Add validation for untrusted Hyper-V values
  hv_sock: Initialize send_buf in hvs_stream_enqueue()
  Drivers: hv: vmbus: Accept hv_sock offers in isolated guests
  Drivers: hv: vmbus: Refactor the ring-buffer iterator functions
