To improve hardware offload debuggability count pending 'add', 'del' and

scheduling new task and decremented when workqueue handler finishes
executing. These counters allow user to diagnose congestion on hardware
offload workqueues that can happen when either CPU is starved and workqueue
jobs are executed at lower rate than new ones are added or when
hardware/driver can't keep up with the rate.
Implement the described counters as percpu counters inside new struct
netns_ft which is stored inside struct net. Expose them via new procfs file
'/proc/net/stats/nf_flowtable' that is similar to existing 'nf_conntrack'

On our RVP platforms using rt298 with combojack we've seen issues with
controls being in incorrect state after suspend/resume cycle. This is
caused by codec driver not setting pins to correct state and causing
codec suspend method to not be called. Which on resume caused codec
registers to be in undefined state. Fix this by setting pins correctly
in jack detect function.
Above problem is caused by the fact that when jack == NULL code doesn't
reach rt298_jack_detect() function which sets pins. Alternatively
problem could be fixed by just moving rt298_jack_detect, but as rt298
codec is similar to rt286, align the code by setting pins explicitly.

BCLK to GPIO functions when probing the i2s bus interface, but missed
adding a check for when devm_pinctrl_get() returns an error. This can lead
to the following NULL pointer dereference on a rockpro64-v2 if there are no
"pinctrl" properties in the i2s device tree node.
Check that i2s->pinctrl is valid before attempting to search for the
bclk_on and bclk_off pinctrl states.

If we set XFRM security policy by calling setsockopt with option
IPV6_XFRM_POLICY, the policy will be stored in 'sock_policy' in 'sock'
struct. However tcp_v6_send_response doesn't look up dst_entry with the
actual socket but looks up with tcp control socket. This may cause a
problem that a RST packet is sent without ESP encryption & peer's TCP
socket can't receive it.
This patch will make the function look up dest_entry with actual socket,
if the socket has XFRM policy(sock_policy), so that the TCP response
packet via this function can be encrypted, & aligned on the encrypted
TCP socket.
Tested: We encountered this problem when a TCP socket which is encrypted
in ESP transport mode encryption, receives challenge ACK at SYN_SENT
state. After receiving challenge ACK, TCP needs to send RST to
establish the socket at next SYN try. But the RST was not encrypted &
peer TCP socket still remains on ESTABLISHED state.
So we verified this with test step as below.
[Test step]
1. Making a TCP state mismatch between client(IDLE) & server(ESTABLISHED).
2. Client tries a new connection on the same TCP ports(src & dst).
3. Server will return challenge ACK instead of SYN,ACK.
4. Client will send RST to server to clear the SOCKET.
5. Client will retransmit SYN to server on the same TCP ports.
[Expected result]
The TCP connection should be established.

Before each invocation of vsnprintf(), do_test() memsets the entire
allocated buffer to a sentinel value. That buffer includes leading and
trailing padding which is never included in the buffer area handed to
vsnprintf (spaces merely for clarity):
pad test_buffer pad
**** **************** ****
Then vsnprintf() is invoked with a bufsize argument <=
BUF_SIZE. Suppose bufsize=10, then we'd have e.g.
|pad | test_buffer |pad |
**** pizza0 **** ****** ****
A B C D E
where vsnprintf() was given the area from B to D.
It is obviously a bug for vsnprintf to touch anything between A and B
or between D and E. The former is checked for as one would expect. But
for the latter, we are actually a little stricter in that we check the
area between C and E.
Split that check in two, providing a clearer error message in case it
was a genuine buffer overrun and not merely a write within the
provided buffer, but after the end of the generated string.
So far, no part of the vsnprintf() implementation has had any use for
using the whole buffer as scratch space, but it's not unreasonable to
allow that, as long as the result is properly nul-terminated and the
return value is the right one. However, it is somewhat unusual, and
most %<something> won't need this, so keep the [C,D] check, but make
it easy for a later patch to make that part opt-out for certain tests.
