Move the is_connected check to the fibre channel transport, as it has no
meaning for other transports. To facilitate this split out a new
nvmf_fail_nonready_command helper that is called by the transport when
it is asked to handle a command on a queue that is not ready.
Also avoid a function call for the queue live fast path by inlining
the check.

Compared to other clients the Linux smb3 client ramps up
credits very slowly, taking more than 128 operations before a
maximum size write could be sent (since the number of credits
requested is only 2 per small operation, causing the credit
limit to grow very slowly).
This lack of credits initially would impact large i/o performance,
when large i/o is tried early before enough credits are built up.

====================
This small series allows test_offload.py selftest to run on modern
distributions which may create BPF programs for cgroups at boot,
like Ubuntu 18.04. We still expect the program list to not be
altered by any other agent while the test is running, but no longer
depend on there being no BPF programs at all at the start.
Fixing the test revealed a small problem with bpftool, which doesn't
report the program load time very accurately. Because nanoseconds
were not taken into account reported load time would fluctuate by
1 second. First patch of the series takes care of fixing that.

Modern distroes increasingly make use of BPF programs. Default
Ubuntu 18.04 installation boots with a number of cgroup_skb

test_offloads.py tries to check if programs and maps are not
leaked on error paths by confirming the list of programs on the
system is empty between tests.
Since we can no longer expect the system to have no BPF objects
at boot try to remember the programs and maps present at the start,
and skip those when scanning the system.

l2tp: pppol2tp_connect() fixes
This series fixes a few remaining issues with pppol2tp_connect().
It doesn't try to prevent invalid configurations that have no effect on
kernel's reliability. That would be work for a future patch set.

If 'fd' is negative, l2tp_tunnel_create() creates a tunnel socket using
the configuration passed in 'tcfg'. Currently, pppol2tp_connect() sets
the relevant fields to zero, tricking l2tp_tunnel_create() into setting
up an unusable kernel socket.
We can't set 'tcfg' with the required fields because there's no way to
get them from the current connect() parameters. So let's restrict
kernel sockets creation to the netlink API, which is the original use
case.

l2tp_session_priv() returns a struct pppol2tp_session pointer only for
PPPoL2TP sessions. In particular, if the session is an L2TP_PWTYPE_ETH
pseudo-wire, l2tp_session_priv() returns a pointer to an l2tp_eth_sess
structure, which is much smaller than struct pppol2tp_session. This
leads to invalid memory dereference when trying to lock ps->sk_lock.

Define cfg.pw_type so that the new session is created with its .pwtype
field properly set (L2TP_PWTYPE_PPP).
Not setting the pseudo-wire type had several annoying effects:
* Invalid value returned in the L2TP_ATTR_PW_TYPE attribute when
dumping sessions with the netlink API.
* Impossibility to delete the session using the netlink API (because
l2tp_nl_cmd_session_delete() gets the deletion callback function
from an array indexed by the session's pseudo-wire type).
Also, there are several cases where we should check a session's
pseudo-wire type. For example, pppol2tp_connect() should refuse to
connect a session that is not PPPoL2TP, but that requires the session's
.pwtype field to be properly set.

commit 079096f103 ("tcp/dccp: install syn_recv requests into ehash
table") introduced an optimization for the handling of child sockets
created for a new TCP connection.
But this optimization passes any data associated with the last ACK of the
connection handshake up the stack without verifying its checksum, because it
calls tcp_child_process(), which in turn calls tcp_rcv_state_process()
directly. These lower-level processing functions do not do any checksum
verification.
Insert a tcp_checksum_complete call in the TCP_NEW_SYN_RECEIVE path to
fix this.
