17 years ago[DCCP]: Twice the wrong reset code in receiving connection-Requests
Gerrit Renker [Thu, 4 Oct 2007 21:52:28 +0000 (14:52 -0700)]
[DCCP]: Twice the wrong reset code in receiving connection-Requests

This fixes two bugs in processing of connection-Requests in
v{4,6}_conn_request:

 1. Due to using the variable `reset_code', the Reset code generated
    internally by dccp_parse_options() is overwritten with the
    initialised value ("Too Busy") of reset_code, which is not what is
    intended.

 2. When receiving a connection-Request on a multicast or broadcast
    address, no Reset should be generated, to avoid storms of such
    packets. Instead of jumping to the `drop' label, the
    v{4,6}_conn_request functions now return 0. Below is why in my
    understanding this is correct:

    When the conn_request function returns < 0, then the caller,
    dccp_rcv_state_process(), returns 1. In all instances where
    dccp_rcv_state_process is called (dccp_v4_do_rcv, dccp_v6_do_rcv,
    and dccp_child_process), a return value of != 0 from
    dccp_rcv_state_process() means that a Reset is generated.

    If on the other hand the conn_request function returns 0, the
    packet is discarded and no Reset is generated.

Note: There may be a related problem when sending the Response, due to
the following.

if (dccp_v6_send_response(sk, req, NULL))
goto drop_and_free;
/* ... */
drop_and_free:
return -1;

In this case, if send_response fails due to transmission errors, the
next thing that is generated is a Reset with a code "Too Busy". I
haven't been able to conjure up such a condition, but it might be good
to change the behaviour here also (not done by this patch).

ax88796: add 93cx6 eeprom support

Hook up the 93cx6 eeprom code to the ax88796 driver and modify the ax88796
driver to read out the mac address from the eeprom.  We need this for the
ax88796 on certain SuperH boards.  The pin configuration used to connect
the eeprom to the ax88796 on these boards is the same as pointed out by the
ax88796 datasheet, so we can probably reuse this code for multiple
platforms in the future.

PHYLIB: fix an interrupt loop potential when halting

Ensure the PHY_HALTED state is not entered with the IRQ asserted as it
could lead to an interrupt loop.

There is a small window in phy_stop(), where the state of the PHY machine
indicates it has been halted, but its interrupt output might still be
unmasked.  If an interrupt goes active right at this moment it will loop as
the phy_interrupt() handler exits immediately with IRQ_NONE if the halted
state is seen.  It is unsafe to extend the phydev spinlock to cover
phy_interrupt().  It is safe to swap the order of the actions though as all
the competing places to unmask the interrupt output of the PHY, which are
phy_change() and phy_timer() are already covered with the lock as is the
sequence in question.

17 years agoPHYLIB: IRQ event workqueue handling fixes
Maciej W. Rozycki [Sat, 29 Sep 2007 05:42:14 +0000 (22:42 -0700)]
PHYLIB: IRQ event workqueue handling fixes

Keep track of disable_irq_nosync() invocations and call enable_irq() the
right number of times if work has been cancelled that would include them.

Now that the call to flush_work_keventd() (problematic because of
rtnl_mutex being held) has been replaced by cancel_work_sync() another
issue has arisen and been left unresolved.  As the MDIO bus cannot be
accessed from the interrupt context the PHY interrupt handler uses
disable_irq_nosync() to prevent from looping and schedules some work to be
done as a softirq, which, apart from handling the state change of the
originating PHY, is responsible for reenabling the interrupt.  Now if the
interrupt line is shared by another device and a call to the softirq
handler has been cancelled, that call to enable_irq() never happens and the
other device cannot use its interrupt anymore as its stuck disabled.

I decided to use a counter rather than a flag because there may be more
than one call to phy_change() cancelled in the queue -- a real one and a
fake one triggered by free_irq() if DEBUG_SHIRQ is used, if nothing else.
Therefore because of its nesting property enable_irq() has to be called the
right number of times to match the number disable_irq_nosync() was called
and restore the original state.  This DEBUG_SHIRQ feature is also the
reason why free_irq() has to be called before cancel_work_sync().

While at it I updated the comment about phy_stop_interrupts() being called
from `keventd' -- this is no longer relevant as the use of
cancel_work_sync() makes such an approach unnecessary.  OTOH a similar
comment referring to flush_scheduled_work() in phy_stop() still applies as
using cancel_work_sync() there would be dangerous.

Checked with checkpatch.pl and at the run time (with and without
DEBUG_SHIRQ).
