net-next: stmmac: rework the speed selection

The current stmmac_adjust_link() part which handle speed have
some if (has_platform) code and my dwmac-sun8i will add more of them.

So we need to handle better speed selection.
Moreover the struct link member speed and port are hard to guess their
purpose. And their unique usage are to be combined for writing speed.

My first try was to create an adjust_link() in stmmac_ops but it duplicate some code

The current solution is to have direct value for 10/100/1000 and a mask for them.

The first 4 patchs fix some minor problem found in stmmac_adjust_link() and reported by Florian Fainelli in my previous serie.
The last patch is the real work.

This series is tested on cubieboard2 (dwmac1000) and opipc (dwmac-sun8i).

Changes since v3:
- Added the patch #4 "Convert old_link to bool" as suggested by Joe Perches
- Changed the speedmask

Changes since v2:
- Use true/false for new_state in patch #1

So this patch replace speed/port by simpler
speed10/speed100/speed1000/speed_mask variables.

In dwmac4_core_init and dwmac1000_core_init, port/speed value was used
directly without using the struct link. This patch convert also their
usage to speedxxx.

Linux TCP stack we analyze exhibits behavior that seems odd to me.
The scenario is as follows (all packets have empty payloads, no window
scaling, rcv/snd window size should not be a factor):

       TEST HARNESS (CLIENT)                        LINUX SERVER

   1.  -                                          LISTEN (server listen,
then accepts)

   2.  - --> <SEQ=100><CTL=SYN>               --> SYN-RECEIVED

   3.  - <-- <SEQ=300><ACK=101><CTL=SYN,ACK>  <-- SYN-RECEIVED

   4.  - --> <SEQ=101><ACK=301><CTL=ACK>      --> ESTABLISHED

   5.  - <-- <SEQ=301><ACK=101><CTL=FIN,ACK>  <-- FIN WAIT-1 (server
opts to close the data connection calling "close" on the connection
socket)

   6.  - --> <SEQ=101><ACK=99999><CTL=FIN,ACK> --> CLOSING (client sends
FIN,ACK with not yet sent acknowledgement number)

   7.  - <-- <SEQ=302><ACK=102><CTL=ACK>      <-- CLOSING (ACK is 102
instead of 101, why?)

... (silence from CLIENT)

   8.  - <-- <SEQ=301><ACK=102><CTL=FIN,ACK>  <-- CLOSING
(retransmission, again ACK is 102)

Now, note that packet 6 while having the expected sequence number,
acknowledges something that wasn't sent by the server. So I would
expect
the packet to maybe prompt an ACK response from the server, and then be
ignored. Yet it is not ignored and actually leads to an increase of the
acknowledgement number in the server's retransmission of the FIN,ACK
packet. The explanation I found is that the FIN  in packet 6 was
processed, despite the acknowledgement number being unacceptable.
Further experiments indeed show that the server processes this FIN,
transitioning to CLOSING, then on receiving an ACK for the FIN it had
send in packet 5, the server (or better said connection) transitions
from CLOSING to TIME_WAIT (as signaled by netstat).

</quote>

Indeed, tcp_rcv_state_process() calls tcp_ack() but
does not exploit the @acceptable status but for TCP_SYN_RECV
state.

What we want here is to send a challenge ACK, if not in TCP_SYN_RECV
state. TCP_FIN_WAIT1 state is not the only state we should fix.

Add a FLAG_NO_CHALLENGE_ACK so that tcp_rcv_state_process()
can choose to send a challenge ACK and discard the packet instead
of wrongly change socket state.

After the mentioned commit, some of our packetdrill tests became flaky.

TCP_SYNCNT socket option can limit the number of SYN retransmits.

retransmits_timed_out() has to compare times computations based on
local_clock() while timers are based on jiffies. With NTP adjustments
and roundings we can observe 999 ms delay for 1000 ms timers.
We end up sending one extra SYN packet.

Gimmick added in commit 6fa12c85 ("Revert Backoff [v3]: Calculate
TCP's connection close threshold as a time value") makes no
real sense for TCP_SYN_SENT sockets where no RTO backoff can happen at
all.

Lets use a simpler logic for TCP_SYN_SENT sockets and remove @syn_set
parameter from retransmits_timed_out()

Now that the switchdev bridge ageing time attribute is propagated to all
switch chips of the fabric, each switch can check if the requested value
is valid and program itself, so that the whole fabric shares a common
ageing time setting.

This is especially needed for switch chips in between others, containing
no bridge port members but evidently used in the data path.

To achieve that, remove the condition which skips the other switches. We
also don't need to identify the target switch anymore, thus remove the
sw_index member of the dsa_notifier_ageing_time_info notifier structure.

On ZII Dev Rev B (with two 88E6352 and one 88E6185) and ZII Dev Rev C
(with two 88E6390X), we have the following hardware configuration:

    # ip link add name br0 type bridge

    br0: port 1(lan6) entered blocking state
    br0: port 1(lan6) entered disabled state

Today, driver has a synchronization point while closing
the device which synchronizes its slowpath interrupt line.
However, that's insufficient as that ISR would schedule the
slowpath-tasklet - so even after ISR is over it's possible the

This patch fixes the kernel oops when release net_device reference in
advance. In function raw_sendmsg(i think the dgram_sendmsg has the same
problem), there is a race condition between dev_put and dev_queue_xmit
when the device is gong that maybe lead to dev_queue_ximt to see
an illegal net_device pointer.

My test kernel is 3.13.0-32 and because i am not have a real 802154
device, so i change lowpan_newlink function to this:

        /* find and hold real wpan device */
        real_dev = dev_get_by_index(src_net, nla_get_u32(tb[IFLA_LINK]));
        if (!real_dev)
                return -ENODEV;
//      if (real_dev->type != ARPHRD_IEEE802154) {
//              dev_put(real_dev);
//              return -EINVAL;
//      }
        lowpan_dev_info(dev)->real_dev = real_dev;
        lowpan_dev_info(dev)->fragment_tag = 0;
        mutex_init(&lowpan_dev_info(dev)->dev_list_mtx);

Also, in order to simulate preempt, i change the raw_sendmsg function
to this:

        skb->dev = dev;
        skb->sk  = sk;
        skb->protocol = htons(ETH_P_IEEE802154);
        dev_put(dev);
        //simulate preempt
        schedule_timeout_uninterruptible(30 * HZ);
        err = dev_queue_xmit(skb);
        if (err > 0)
                err = net_xmit_errno(err);

and this is my userspace test code named test_send_data:

int main(int argc, char **argv)
{
        char buf[127];
        int sockfd;
        sockfd = socket(AF_IEEE802154, SOCK_RAW, 0);
        if (sockfd < 0) {
                printf("create sockfd error: %s\n", strerror(errno));
                return -1;
        }
        send(sockfd, buf, sizeof(buf), 0);
        return 0;
}

This is my test case:

This field is sizeof of corresponding kmem_cache so it can't be negative.

Space will be saved after 32-bit kmem_cache_create() patch.
