wimax: allow specifying debug levels as command line option

Add "debug" module options to all the wimax modules (including
drivers) so that the debug levels can be set upon kernel boot or

This is needed as currently there was a limitation where the debug

enumerated. This made it difficult to debug issues that made a device

15 years agowimax/i2400m: during probe, call sdio_disable at most once

wimax/i2400m: during probe, call sdio_disable at most once

In the Intel Wireless Multicomm 3200, the initialization is
orchestrated by a component called Top. This component also monitors
how many times a function is reset (via sdio_disable) to detect
possible issues and will reset the whole multifunction device if any
function triggers a maximum reset level.

During WiMAX's probe, the driver needs to wait for Top to come up
before it can enable the WiMAX function. If it cannot, it will return
-ENODEV and the Top driver will rescan the SDIO bus once done
loading.

Currently, the WiMAX SDIO probe routine was trying a few times before
returning -ENODEV, and this was triggering Top's too-many-resets
detector. This is, in any case, unnecessary because the Top driver will
force the bus rescan when the functions can be probed successfully.

Added then a maxtries argument to i2400ms_enable_func() and set it to
1 when calling from probe. We want to reuse this function instead of
flat calling out sdio_enable_func() to take advantage of hardware
quirk workarounds.

TI DaVinci EMAC: Clear statistics register properly.

The mechanism to clear the statistics register is dependent
on the status of GMIIEN bit in MAC control register. If the
GMIIEN bit is set, the stats registers are write to decrement.
If the GMIIEN bit is cleared, the stats registers are plain
read/write registers. The stats register clearing operation
must take into account the current state of GMIIEN as it
can be cleared when the interface is brought down.

With existing implementation logic, querying for interface stats
when the interface is down, can corrupt the statistics counters.

15 years agotcp: fix tcp_defer_accept to consider the timeout
Willy Tarreau [Tue, 13 Oct 2009 07:27:40 +0000 (00:27 -0700)]
tcp: fix tcp_defer_accept to consider the timeout

I was trying to use TCP_DEFER_ACCEPT and noticed that if the
client does not talk, the connection is never accepted and
remains in SYN_RECV state until the retransmits expire, where
it finally is deleted. This is bad when some firewall such as
netfilter sits between the client and the server because the
firewall sees the connection in ESTABLISHED state while the
server will finally silently drop it without sending an RST.

This behaviour contradicts the man page which says it should
wait only for some time :

       TCP_DEFER_ACCEPT (since Linux 2.4)
          Allows a listener to be awakened only when data arrives
          on the socket.  Takes an integer value  (seconds), this
          can  bound  the  maximum  number  of attempts TCP will
          make to complete the connection. This option should not
          be used in code intended to be portable.

Also, looking at ipv4/tcp.c, a retransmit counter is correctly
computed :

        case TCP_DEFER_ACCEPT:
                icsk->icsk_accept_queue.rskq_defer_accept = 0;
                if (val > 0) {
                        /* Translate value in seconds to number of
                         * retransmits */
                        while (icsk->icsk_accept_queue.rskq_defer_accept < 32 &&
                               val > ((TCP_TIMEOUT_INIT / HZ) <<
                                       icsk->icsk_accept_queue.rskq_defer_accept))
                                icsk->icsk_accept_queue.rskq_defer_accept++;
                        icsk->icsk_accept_queue.rskq_defer_accept++;
                }
                break;

==> rskq_defer_accept is used as a counter of retransmits.

But in tcp_minisocks.c, this counter is only checked. And in
fact, I have found no location which updates it. So I think
that what was intended was to decrease it in tcp_minisocks
whenever it is checked, which the trivial patch below does.
