This patch adds a test case to reproduce the SCTP DATA chunk retransmission
timeout issue caused by the improper SCTP collision processing in netfilter
nf_conntrack_proto_sctp.
In this test, client sends a INIT chunk, but the INIT_ACK replied from
server is delayed until the server sends a INIT chunk to start a new
connection from its side. After the connection is complete from server
side, the delayed INIT_ACK arrives in nf_conntrack_proto_sctp.
The delayed INIT_ACK should be dropped in nf_conntrack_proto_sctp instead
of updating the vtag with the out-of-date init_tag, otherwise, the vtag
in DATA chunks later sent by client don't match the vtag in the conntrack
entry and the DATA chunks get dropped.

This patch fixes it as below:

- set ct->proto.sctp.init[dir].

ct->proto.sctp.vtag[!dir] != ih->init_tag. (Scenario B, Scenario C)
- drop it if ct->proto.sctp.init[dir] && ct->proto.sctp.init[!dir] &&
ct->proto.sctp.vtag[!dir] != ih->init_tag. (Scenario A)
In SCTP_CID_COOKIE_ACK processing:
- clear ct->proto.sctp.init[dir] and ct->proto.sctp.init[!dir].
(Scenario D)
Also, it's important to allow the ct state to move forward with cookie_echo
and cookie_ack from the opposite dir for the collision scenarios.
There are also other Scenarios where it should allow the packet through,
addressed by the processing above:
Scenario C: new CT is created by INIT_ACK.
Scenario D: start INIT on the existing ESTABLISHED ct.
Scenario E: start INIT after the old collision on the existing ESTABLISHED

BO's RSS is updated every time new pages are allocated on demand and mapped
for the object at GPU page fault's IRQ handler, but only for heap buffers.
The reason this is unnecessary for non-heap buffers is that they are mapped
onto the GPU's VA space and backed by physical memory in their entirety at
BO creation time.
This calculation is unnecessary for imported PRIME objects, since heap
buffers cannot be exported by our driver, and the actual BO RSS size is the
one reported in its attached dmabuf structure.

Some BO's might be mapped onto physical memory chunkwise and on demand,
like Panfrost's tiler heap. In this case, even though the
drm_gem_shmem_object page array might already be allocated, only a very
small fraction of the BO is currently backed by system memory, but
drm_show_memory_stats will then proceed to add its entire virtual size to
the file's total resident size regardless.
This led to very unrealistic RSS sizes being reckoned for Panfrost, where
said tiler heap buffer is initially allocated with a virtual size of 128
MiB, but only a small part of it will eventually be backed by system memory
after successive GPU page faults.
Provide a new DRM object generic function that would allow drivers to
return a more accurate RSS and purgeable sizes for their BOs.

The drm-stats fdinfo tags made available to user space are drm-engine,
drm-cycles, drm-max-freq and drm-curfreq, one per job slot.
This deviates from standard practice in other DRM drivers, where a single
set of key:value pairs is provided for the whole render engine. However,
Panfrost has separate queues for fragment and vertex/tiler jobs, so a
decision was made to calculate bus cycles and workload times separately.
Maximum operating frequency is calculated at devfreq initialisation time.
Current frequency is made available to user space because nvtop uses it
when performing engine usage calculations.
It is important to bear in mind that both GPU cycle and kernel time numbers
provided are at best rough estimations, and always reported in excess from
the actual figure because of two reasons:
- Excess time because of the delay between the end of a job processing,
the subsequent job IRQ and the actual time of the sample.
- Time spent in the engine queue waiting for the GPU to pick up the next
job.
To avoid race conditions during enablement/disabling, a reference counting
mechanism was introduced, and a job flag that tells us whether a given job
increased the refcount. This is necessary, because user space can toggle
cycle counting through a debugfs file, and a given job might have been in
flight by the time cycle counting was disabled.
The main goal of the debugfs cycle counter knob is letting tools like nvtop
or IGT's gputop switch it at any time, to avoid power waste in case no
engine usage measuring is necessary.
Also add a documentation file explaining the possible values for fdinfo's
engine keystrings and Panfrost-specific drm-curfreq-<keystr> pairs.

Newer versions of firmware will pre-reserve 1 VNIC for every possible

when assigning VNICs to the VFs. These pre-reserved VNICs for the
inactive VFs should be subtracted from the global pool before
assigning them to the active VFs.
Not doing so may cause discrepancies that ultimately may cause some VFs to

This is in preparation for upcoming patches in the series.
Driver has to expose more threshold temperatures through the
hwmon sysfs interface. More code will be added and do not
want to overload bnxt.c.

Driver currently does hwmon device register and unregister
in open and close() respectively. As a result, user will not
be able to query hwmon temperature when interface is in
ifdown state.
Enhance it by moving the hwmon register/unregister to the
probe/remove functions.

In some OVS environments the TCP pseudo header checksum may need to be
recomputed. Currently this is only done when the interface instance is
configured for "Trunk Mode". We found the issue also occurs in some
Kubernetes environments, these environments do not use "Trunk Mode",
therefor the condition is removed.
Performance tests with this change show only a fractional decrease in
throughput (< 0.2%).

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says:
The kernel recently added new warnings, one of which triggers a known
false positive on the etas_es58x module. In an effort to keep
es58x_etas free of any W=12 (excluding those produced by foreign
headers), add a workaround to silence it.
While at it, this series also fix a checkpatch warning which I knew
existed for a long time but was too lazy to tackle.
v2 -> v3:
* if the parsing of one of the version/revision numbers fail,
es58x_parse_product_info() immediately returns. If this occurs early,
the other version/revision numbers would still be set to zero (which
is now considered a valid version number). Set the version and
revision to an invalid number before starting the parsing so that
everything is set even if an early return occurs.
v1 -> v2:
* v1 had two different check logics for the version numbers:
- check that none of the sub-version number are zero to make sure
the parsing succeeded
- check that all of the sub-version number fit the expected digit
range to please GCC.
v2 simplifies things by merging those two logics together.

If a duplicate attribute is found using kset_find_obj(), a reference
to that attribute is returned which needs to be disposed accordingly
using kobject_put(). Use kobject_put() to dispose the duplicate
attribute in such a case.
As a side note, a very similar bug was fixed in
commit 7295a996fd ("platform/x86: dell-sysman: Fix reference leak"),
so it seems that the bug was copied from that driver.
