IPoIB: Fix memory leak of multicast group structures · 988bd503

由 Eli Cohen 提交于 1月 12, 2006

The current handling of multicast groups in IPoIB ends up never
freeing send-only multicast groups.  It turns out the logic was much
more complicated than it needed to be; we can fix this bug and
completely kill ipoib_mcast_dev_down() at the same time.

IPoIB: Fix address handle refcounting for multicast groups · 97460df3

由 Eli Cohen 提交于 1月 10, 2006

Multiple ipoib_neigh structures on mcast->neigh_list may point to the
same ah. This means that ipoib_mcast_free() can't just make a list of
ah structs to free, since this might end up trying to add the same ah
to the list more than once. Handle this in ipoib_multicast.c in the
same way as it is handled in ipoib_main.c for struct ipoib_path.

IB: Add node_guid to struct ib_device · cf311cd4

由 Sean Hefty 提交于 1月 10, 2006

Add a node_guid field to struct ib_device. It is the responsibility
of the low-level driver to initialize this field before registering a
device with the midlayer. Convert everyone to looking at this field
instead of calling ib_query_device() when all they want is the node
GUID, and remove the node_guid field from struct ib_device_attr.

IB/mthca: prevent event queue overrun · 92898522

由 Michael S. Tsirkin 提交于 1月 09, 2006

I am seeing EQ overruns in SDP stress tests: if the CQ completion
handler arms a CQ, this could generate more EQEs, so that EQ will
never get empty and consumer index will never get updated.

This is similiar to what we have with command interface:
		/*
		 * cmd_event() may add more commands.
		 * The card will think the queue has overflowed if
		 * we don't tell it we've been processing events.
		 */
However, for completion events, we *don't* want to update the consumer
index on each event. So, perform EQ doorbell coalescing: allocate EQs
with some spare EQEs, and update once we run out of them.

The value 0x80 was selected to avoid any performance impact.

For all pages except possibly the last one, the byte beyond the buffer
end must be page aligned.  Therefore, when computing the page shift to
