ibmveth: Fix alignment of rx queue bug

2012-09-05T21:45:23+00:00

This patch fixes a bug found by Nish Aravamudan
(https://lkml.org/lkml/2012/5/15/220) where the driver is not following
the spec (it is not aligning the rx buffer on a 16-byte boundary) and the
hypervisor aborts the registration, making the device unusable.

The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461)
to replace the kmalloc+map for a single call to dma_alloc_coherent()
because that function always aligns to a 16-byte boundary.

The stable trees will run into this bug whenever the rx buffer kmalloc call
returns something not aligned on a 16-byte boundary.

ehea: fix losing of NEQ events when one event occurred early

2012-05-11T02:45:54+00:00

The NEQ interrupt is only triggered when there was no previous pending
interrupt. If we request irq handling after an interrupt has occurred,
we will never get an interrupt until we call H_RESET_EVENTS.

Events seem to be cleared when we first register the NEQ. So, when we
requested irq handling right after registering it, a possible race with
an interrupt was much less likely. Now, there is a chance we may lose
this race and never get any events.

The fix here is to poll and acknowledge any events that might have
happened right after registering the irq handler.

ehea: fix promiscuous mode

2012-04-26T09:07:45+00:00

commit a4910b744486254cfa61995954c118fb2283c4fd has broken promiscuous
mode, which is never set. port->promisc just reflects the last setting
of PROMISCUOUS mode to avoid doing an extra hypercall when it's already
set.

However, since it may fail because of hypervisor permissions, we should
still respect the multicast settings and not simply exit after setting
promiscuous mode.

ehea: fix allmulticast support

2012-04-26T09:07:45+00:00

There was a bug in the mask of regtype parameter for registering a
multicast filter. It was ignoring the scope bit, which was wrongly being
used for all filters. The SCOPE_ALL value adds a filter that allows all
multicast packets and ignores the MAC parameter, just what allmulticast
needs. The normals filters, however, should not use SCOPE_ALL.

ehea: only register irq after setting up ports

2012-04-24T04:36:35+00:00

If we receive an interrupt too early before we set up ports in the probe
function, there won't be any port ready to handle it.

Only registering the irq after the ports are setup fixes the problem,
and works fine without losing any interrupts.

This causes crashes in some situations:

powerpc+sparc/vio: Modernize driver registration

2012-03-28T00:33:24+00:00

This makes vio_register_driver() get the module owner & name at compile
time like PCI drivers do, and adds a name pointer directly in struct
vio_driver to avoid having to explicitly initialize the embedded
struct device.

ehea: restore multicast and rx_errors fields

2012-03-08T08:23:04+00:00

Commit 239c562c94d (ehea: Add 64bit statistics) added a regression,
since we no longer report multicast & rx_errors fields, taken from
port->stats structure. These fields are updated in ehea_update_stats()
every second.
