[RESENT,PATCHv7,0/6] net/tls: fixes for NVMe-over-TLS

Message

Hi all,

here are some small fixes to get NVMe-over-TLS up and running.
The first set are just minor modifications to have MSG_EOR handled
for TLS, but the second set implements the ->read_sock() callback for tls_sw
which I guess could do with some reviews.

As usual, comments and reviews are welcome.

Changes to the original submission:
- Add a testcase for MSG_EOR handling

Changes to v2:
- Bail out on conflicting message flags
- Rework flag handling

Changes to v3:
- Return -EINVAL on conflicting flags
- Rebase on top of net-next

Changes to v4:
- Add tlx_rx_reader_lock() to read_sock
- Add MSG_EOR handling to tls_sw_readpages()

Changes to v5:
- Rebase to latest upstream
- Split tls_rx_reader_lock() as suggested by Sagi

Changes to v6:
- Fixup tls_strp_read_copyin() to avoid infinite recursion
  in tls_read_sock()
- Rework tls_read_sock() to read all available data

Hannes Reinecke (6):
  net/tls: handle MSG_EOR for tls_sw TX flow
  net/tls: handle MSG_EOR for tls_device TX flow
  selftests/net/tls: add test for MSG_EOR
  net/tls: Use tcp_read_sock() instead of ops->read_sock()
  net/tls: split tls_rx_reader_lock
  net/tls: implement ->read_sock()
