Debatable -- the current comment is located at the callsite of
ops->get_sset_count(), which is where an implementor might think to add
a new call. Not all the numeric fields in ethtool_drvinfo are obtained
from ->get_sset_count().
Hence the "some" in the attached patch to include/linux/ethtool.h,
addressing your comment.

We got system OOM while running some UDP netperf testing on the loopback
device. The case is multiple senders sent stream UDP packets to a single
receiver via loopback on local host. Of course, the receiver is not able
to handle all the packets in time. But we surprisingly found that these
packets were not discarded due to the receiver's sk->sk_rcvbuf limit.
Instead, they are kept queuing to sk->sk_backlog and finally ate up all
the memory. We believe this is a secure hole that a none privileged user
can crash the system.
The root cause for this problem is, when the receiver is doing
__release_sock() (i.e. after userspace recv, kernel udp_recvmsg ->
skb_free_datagram_locked -> release_sock), it moves skbs from backlog to
sk_receive_queue with the softirq enabled. In the above case, multiple
busy senders will almost make it an endless loop. The skbs in the
backlog end up eat all the system memory.
The issue is not only for UDP. Any protocols using socket backlog is
potentially affected. The patch adds limit for socket backlog so that
the backlog size cannot be expanded endlessly.

Handling HT configuration changes involved setting the channel
with the new HT parameters and then issuing a rate_update()
notification to the driver.
This behavior changed after the off-channel changes. Now, the channel
is not updated with the new HT params in enable_ht() - instead, it
is now done when the scan work terminates. This results in the driver
depending on stale information, defaulting to non-HT mode always.
Fix this by passing the new channel type to the driver.

When I merged the bundle creation code, I introduced a bogus
flowi value in the bundle. Instead of getting from the caller,
it was instead set to the flow in the route object, which is
totally different.
The end result is that the bundles we created never match, and
we instead end up with an ever growing bundle list.

I have a Delkin Devices compact flash card that isn't being recognized using the
SATA/PATA drivers.
The card is recognized and works with the deprecated ATA drivers.
The error I am seeing is:
ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0)
I tracked it down to ata_id_is_cfa() in include/linux/ata.h.
The Delkin card has id[0] set to 0x844a and id[83] set to 0.
This isn't what the kernel expects and is probably incorrect.
The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().

Traditional IDE interface sucks in that it doesn't have a reliable IRQ
pending bit, so if the controller raises IRQ while the driver is
expecting it not to, the IRQ won't be cleared and eventually the IRQ
line will be killed by interrupt subsystem. Some controllers have
non-standard mechanism to indicate IRQ pending so that this condition
can be detected and worked around.
This patch adds an optional operation ->sff_irq_check() which will be
called for each port from the ata_sff_interrupt() if an unexpected
interrupt is received. If the operation returns %true,
->sff_check_status() and ->sff_irq_clear() will be cleared for the
port. Note that this doesn't mark the interrupt as handled so it
won't prevent IRQ subsystem from killing the IRQ if this mechanism
fails to clear the spurious IRQ.
This patch also implements ->sff_irq_check() for ata_piix. Note that
this adds slight overhead to shared IRQ operation as IRQs which are
destined for other controllers will trigger extra register accesses to
check whether IDE interrupt is pending but this solves rare screaming
IRQ cases and for some curious reason also helps weird BIOS related
glitch on Samsung n130 as reported in bko#14314.
http://bugzilla.kernel.org/show_bug.cgi?id=14314
* piix_base_ops dropped as suggested by Sergei.
* Spurious IRQ detection doesn't kick in anymore if polling qc is in
progress. This provides less protection but some controllers have
possible data corruption issues if the wrong register is accessed
while a command is in progress.

large resource data type.
