MFA2 format parsing and the firmware flash state machine logic. As the
module implements common logic which will be needed by various different
Mellanox drivers, it defines a set of callbacks needed to interact with the

Patches 1-5 implement the needed mlxfw callbacks in the mlxsw spectrum

 (1) All the local endpoint, peer and call lists, locks, counters, etc. are
     moved into the per-namespace record.

 (2) All the connection tracking is moved into the per-namespace record
     with the exception of the client connection ID tree, which is kept
     global so that connection IDs are kept unique per-machine.

 (3) Each namespace gets its own epoch.  This allows each network namespace
     to pretend to be a separate client machine.

 (4) The /proc/net/rxrpc_xxx files are now called /proc/net/rxrpc/xxx and
     the contents reflect the namespace.

fs/afs/ should be okay with this patch as it explicitly requires the current
net namespace to be init_net to permit a mount to proceed at the moment.  It
will, however, need updating so that cells, IP addresses and DNS records are
per-namespace also.

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

tcp: better validation of received ack sequences

Paul Fiterau Brostean reported :

<quote>
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.

Gimmick added in commit 6fa12c850314 ("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

To achieve that, remove the condition which skips the other switches. We

net: ieee802154: fix net_device reference release too early

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;

David S. Miller [Mon, 22 May 2017 23:37:40 +0000 (19:37 -0400)]
Merge branch 'dsa-distribute-switch-events'

Vivien Didelot says:

====================
net: dsa: distribute switch events

DSA is by nature the support for a switch fabric, which can be composed
of a single, or multiple interconnected Ethernet switch chips.

The current DSA core behavior is to identify the slave port targeted by
a request (e.g. adding a VLAN entry), and program the switch chip to
which it belongs accordingly.

This is problematic in a multi-chip environment, since all chips of a
fabric must be aware of most configuration changes. Here are some
concrete examples in a 3-chip environment:

         [CPU].................... (mdio)
    (eth0) |   :       :          :
          _|_____    _______    _______
         [__sw0__]--[__sw1__]--[__sw2__]
          |  |  |    |  |  |    |  |  |
          v  v  v    v  v  v    v  v  v
          p1 p2 p3   p4 p5 p6   p7 p8 p9

If you add a VLAN entry on p7, sw2 gets programmed, but frames won't
reach the CPU interface in a VLAN filtered setup. sw0 and sw1 also need
to be programmed. The same problem comes with MAC addresses (FDB, MDB),
or ageing time changes for instance.

This patch series uses the notification chain introduced for bridging,
to notify not only bridge, but switchdev attributes and objects events
to all switch chips of the fabric.

An ugly debug message printing the ignored event and switch info in the
code handling the switch VLAN events would give us:

    # bridge vlan add dev p7 vid 42
    sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase)
    sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase)
    sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase)
    sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase)

To achieve that, patches 1-8 change the scope of the bridge and
switchdev callbacks from the DSA slave device to the generic DSA port,
so that the port-wide API can be used later for switch ports not exposed
to userspace, such as CPU and DSA links.

Patches 9-15 move the DSA port specific functions in a new port.c file.

Patches 16-20 introduce new events to notify the fabric about switchdev
attributes and objects manipulation.

This patch series only adds the plumbing to support a distributed
configuration, but for the moment, each switch chip ignores events from
other chips of the fabric, to keep the current behavior.

The next patch series will add support for cross-chip configuration of
bridge ageing time, VLAN and MAC address databases operations, etc.
