After sending device capability queries and requests to the vNIC Server,
an interrupt is triggered and the responses are written to the driver's
CRQ response buffer. Since the interrupt can be triggered before all
responses are written and visible to the partition, there is a danger
that the interrupt handler or tasklet can terminate before all responses
are read, resulting in a failure to initialize the device.
To avoid this scenario, when capability commands are sent, we set
a flag that will be checked in the following interrupt tasklet that
will handle the capability responses from the server. Once all
responses have been handled, the flag is disabled; and the tasklet
is allowed to terminate.

Diving the divider by the multiplier before applying to the input.
When this would "divide by zero", divide the multiplier by the divider
first then multiply the input by this value.
Currently user2creds outputs zero when input value is bigger than the
number of slices and lower than scale.
This as then user input is applied an integer divide operation to
a number greater than itself (scale).
That rounds up to zero, then we multiply zero by the credits slice size.
iptables -t filter -I INPUT --protocol tcp --match hashlimit
--hashlimit 40/second --hashlimit-burst 20 --hashlimit-mode srcip
--hashlimit-name syn-flood --jump RETURN
thus trigger the overflow detection code:
xt_hashlimit: overflow, try lower: 25000/20
(25000 as hashlimit avg and 20 the burst)
Here:
134217 slices of (HZ * CREDITS_PER_JIFFY) size.
500000 is user input value
1000000 is XT_HASHLIMIT_SCALE_v2
gives: 0 as user2creds output
Setting burst to "1" typically solve the issue ...
but setting it to "40" does too !
This is on 32bit arch calling into revision 2 of hashlimit.

If we use before/after to add an element to an empty list it will cause
a kernel panic.
$> cat crash.restore
create a hash:ip
create b hash:ip
create test list:set timeout 5 size 4
add test b before a
$> ipset -R < crash.restore
Executing the above will crash the kernel.

What happens is that a write to /dev/sg is given a request with non-zero
->iovec_count combined with zero ->dxfer_len. Or with ->dxferp pointing
to an array full of empty iovecs.
Having write permission to /dev/sg shouldn't be equivalent to the
ability to trigger BUG_ON() while holding spinlocks...

Don't crash the machine just because of an empty transfer. Use WARN_ON()
combined with returning an error.
Found by Dmitry Vyukov and syzkaller.
[ Changed to "WARN_ON_ONCE()". Al has a patch that should fix the root
cause, but a BUG_ON() is not acceptable in any case, and a WARN_ON()
might still be a cause of excessive log spamming.
NOTE! If this warning ever triggers, we may end up leaking resources,
since this doesn't bother to try to clean the command up. So this
WARN_ON_ONCE() triggering does imply real problems. But BUG_ON() is
much worse.
People really need to stop using BUG_ON() for "this shouldn't ever
happen". It makes pretty much any bug worse. - Linus ]

The usual small smattering of driver specific fixes. A few bits that
stand out here:
- The R-Car patches adding fallbacks are just adding new compatible
strings to the driver so that device trees are written in a more
robustly future proof fashion, this isn't strictly a fix but it's
just new IDs and it's better to get it into mainline sooner to
improve the ABI.
- The DesignWare "switch to new API part 2" patch is actually a
misleadingly titled fix for a bit that got missed in the original
conversion.
