====================
linux-can-next-for-5.10-20201007
The first 3 patches are by me and fix several warnings found
when compiling the kernel with W=1.
Lukas Bulwahn's patch adjusts the MAINTAINERS file, to accommodate
the renaming of the mcp251xfd driver.
Vincent Mailhol contributes 3 patches for the CAN networking layer.
First error queue support is added the the CAN RAW protocol.
The second patch converts the get_can_dlc() and get_canfd_dlc()
in-Kernel-only macros from using __u8 to u8.
The third patch adds a helper function to calculate the length of
one bit in in multiple of time quanta.
Oliver Hartkopp's patch add support for the ISO 15765-2:2016
transport protocol to the CAN stack.
Three patches by Lad Prabhakar add documentation for various
new rcar controllers to the device tree bindings of the rcar_can
and rcan_canfd driver.
Michael Walle's patch adds various processors to the flexcan
driver binding documentation.
The next two patches are by me and target the flexcan driver aswell.
The remove the ack_grp and ack_bit from the fsl,stop-mode DT property
and the driver, as they are not used anymore. As these are the last
two arguments this change will not break existing device trees.
The last three patches are by Srinivas Neeli and target
the xilinx_can driver.
The first one increases the lower limit for the bit rate
prescaler to 2, the other two fix sparse and coverity findings.

At first when sendpage gets called, if there is more data, 'more' in
tls_push_data() gets set which later sets pending_open_record_frags, but
when there is no more data in file left, and last time tls_push_data()
gets called, pending_open_record_frags doesn't get reset. And later when
2 bytes of encrypted alert comes as sendmsg, it first checks for
pending_open_record_frags, and since this is set, it creates a record with
0 data bytes to encrypt, meaning record length is prepend_size + tag_size
only, which causes problem.
We should set/reset pending_open_record_frags based on more bit.

When a ICMPV6_PKT_TOOBIG report a next-hop MTU that is less than the IPv6
minimum link MTU, the estimated path MTU is reduced to the minimum link
MTU. This behaviour breaks TAHI IPv6 Core Conformance Test v6LC4.1.6:
Packet Too Big Less than IPv6 MTU.
Referring to RFC 8201 section 4: "If a node receives a Packet Too Big
message reporting a next-hop MTU that is less than the IPv6 minimum link
MTU, it must discard it. A node must not reduce its estimate of the Path
MTU below the IPv6 minimum link MTU on receipt of a Packet Too Big
message."

When processing a system suspend request we suspend modem endpoints
if they are enabled, and call ipa_cmd_tag_process() (which issues
IPA commands) to ensure the IPA pipeline is cleared. It is an error
to attempt to issue an IPA command before setup is complete, so this
is clearly a bug. But we also shouldn't suspend or resume any
endpoints that have not been set up.
Have ipa_endpoint_suspend() and ipa_endpoint_resume() immediately
return if setup hasn't completed, to avoid any attempt to configure
endpoints or issue IPA commands in that case.

Move the in-kernel kprobes insn page to text segment. Rationale:
having that page in rw data segment is suboptimal, since as soon as a
kprobe is set, this will split the 1:1 kernel mapping for a single
page which get new permissions.
Note: there is always at least one kprobe present for the kretprobe
trampoline; so the mapping will always be split into smaller 4k
mappings because of this.
Moving the kprobes insn page into text segment makes sure that the
page is mapped RO/X in any case, and avoids that the 1:1 mapping is
split.
The kprobe insn_page is defined as a dummy function which is filled
with "br %r14" instructions.

for a test harness to detect whether the number of tests run matches the

Although we have not seen any actual examples where KUnit doesn't work
because it runs in the late init phase of the kernel, it has been a
concern for some time that this could potentially be an issue in the
future. So, remove KUnit from init calls entirely, instead call directly
from kernel_init() so that KUnit runs after late init.

Currently, the devlink_port structure is stored within the ice_pf. This
made sense because we create a single devlink_port for each PF. This
setup does not mesh with the abstractions in the driver very well, and
led to a flow where we accidentally call devlink_port_unregister twice
during error cleanup.
In particular, if devlink_port_register or devlink_port_unregister are
called twice, this leads to a kernel panic. This appears to occur during
some possible flows while cleaning up from a failure during driver
probe.
If register_netdev fails, then we will call devlink_port_unregister in
ice_cfg_netdev as it cleans up. Later, we again call
devlink_port_unregister since we assume that we must cleanup the port
that is associated with the PF structure.
This occurs because we cleanup the devlink_port for the main PF even
though it was not allocated. We allocated the port within a per-VSI
function for managing the main netdev, but did not release the port when
cleaning up that VSI, the allocation and destruction are not aligned.
Instead of attempting to manage the devlink_port as part of the PF
structure, manage it as part of the PF VSI. Doing this has advantages,
as we can match the de-allocation of the devlink_port with the
unregister_netdev associated with the main PF VSI.
Moving the port to the VSI is preferable as it paves the way for
handling devlink ports allocated for other purposes such as SR-IOV VFs.
Since we're changing up how we allocate the devlink_port, also change
the indexing. Originally, we indexed the port using the PF id number.
This came from an old goal of sharing a devlink for each physical
function. Managing devlink instances across multiple function drivers is
not workable. Instead, lets set the port number to the logical port
number returned by firmware and set the index using the VSI index
(sometimes referred to as VSI handle).

CalledProcessError stores the output of the failed process as `bytes`,
not a `str`.
So when we log it on build error, the make output is all crammed into
one line with "\n" instead of actually printing new lines.

The main purpose of the profiler test to check different llvm generation
patterns to make sure the verifier can load these large programs.
Note that profiler.inc.h test doesn't follow strict kernel coding style.
The code was formatted in the kernel style, but variable declarations are
kept as-is to preserve original llvm IR pattern.
profiler1.c should pass with older and newer llvm
profiler[23].c may fail on older llvm that don't have:
https://reviews.llvm.org/D85570
because llvm may do speculative code motion optimization that
will generate code like this:
// r9 is a pointer to map_value
// r7 is a scalar
17: bf 96 00 00 00 00 00 00 r6 = r9
18: 0f 76 00 00 00 00 00 00 r6 += r7
19: a5 07 01 00 01 01 00 00 if r7 < 257 goto +1
20: bf 96 00 00 00 00 00 00 r6 = r9
// r6 is used here
The verifier will reject such code with the error:
"math between map_value pointer and register with unbounded min value is not allowed"
At insn 18 the r7 is indeed unbounded. The later insn 19 checks the bounds and
the insn 20 undoes map_value addition. It is currently impossible for the
verifier to understand such speculative pointer arithmetic. Hence llvm D85570
addresses it on the compiler side.

Under register pressure the llvm may spill registers with bounds into the stack.
The verifier has to track them through spill/fill otherwise many kinds of bound
errors will be seen. The spill/fill of induction variables was already
happening. This patch extends this logic from tracking spill/fill of a constant
into any bounded register. There is no need to track spill/fill of unbounded,
since no new information will be retrieved from the stack during register fill.
Though extra stack difference could cause state pruning to be less effective, no
adverse affects were seen from this patch on selftests and on cilium programs.

The llvm register allocator may use two different registers representing the
same virtual register. In such case the following pattern can be observed:
1047: (bf) r9 = r6
1048: (a5) if r6 < 0x1000 goto pc+1
1050: ...
1051: (a5) if r9 < 0x2 goto pc+66
1052: ...
1053: (bf) r2 = r9 /* r2 needs to have upper and lower bounds */
This is normal behavior of greedy register allocator.
The slides 137+ explain why regalloc introduces such register copy:
http://llvm.org/devmtg/2018-04/slides/Yatsina-LLVM%20Greedy%20Register%20Allocator.pdf
There is no way to tell llvm 'not to do this'.
Hence the verifier has to recognize such patterns.
In order to track this information without backtracking allocate ID
for scalars in a similar way as it's done for find_good_pkt_pointers().
When the verifier encounters r9 = r6 assignment it will assign the same ID
to both registers. Later if either register range is narrowed via conditional
jump propagate the register state into the other register.
Clear register ID in adjust_reg_min_max_vals() for any alu instruction. The
register ID is ignored for scalars in regsafe() and doesn't affect state
pruning. mark_reg_unknown() clears the ID. It's used to process call, endian
and other instructions. Hence ID is explicitly cleared only in
adjust_reg_min_max_vals() and in 32-bit mov.

As the dpm clock table is needed during DC HW initialization.
And that (DC HW initialization) comes before smu_late_init()
where current APU dpm clock table setup is performed. So, NULL
pointer dereference will be triggered. By moving APU dpm clock
table setup to smu_hw_init(), this can be avoided.

We want to use the dev_* functions here rather than the pr_* variants.
Switch to using dev_warn() which mirrors what we do on other asics.

Moshe Shemesh says:
====================
Add devlink reload action and limit options
Introduce new options on devlink reload API to enable the user to select
the reload action required and constrains limits on these actions that he
may want to ensure. Complete support for reload actions in mlx5.
The following reload actions are supported:
driver_reinit: driver entities re-initialization, applying devlink-param
and devlink-resource values.
fw_activate: firmware activate.
The uAPI is backward compatible, if the reload action option is omitted
from the reload command, the driver reinit action will be used.
Note that when required to do firmware activation some drivers may need
to reload the driver. On the other hand some drivers may need to reset
the firmware to reinitialize the driver entities. Therefore, the devlink
reload command returns the actions which were actually performed.
By default reload actions are not limited and driver implementation may
include reset or downtime as needed to perform the actions.
However, if reload limit is selected, the driver should perform only if
it can do it while keeping the limit constraints.
Reload limit added:
no_reset: No reset allowed, no down time allowed, no link flap and no
configuration is lost.
Each driver which supports devlink reload command should expose the
reload actions and limits supported.
Add reload stats to hold the history per reload action per limit.
For example, the number of times fw_activate has been done on this
device since the driver module was added or if the firmware activation
was done with or without reset.
Patch 1 changes devlink_reload_supported() param type to enable using
it before allocating devlink.
Patch 2-3 add the new API reload action and reload limit options to
devlink reload.
Patch 4-5 add reload stats and remote reload stats. These stats are
exposed through devlink dev get.
Patches 6-11 add support on mlx5 for devlink reload action fw_activate
and handle the firmware reset events.
Patches 12-13 add devlink enable remote dev reset parameter and use it
in mlx5.
Patches 14-15 mlx5 add devlink reload limit no_reset support for
fw_activate reload action.
Patch 16 adds documentation file devlink-reload.rst

Add support for devlink reload action fw_activate with reload limit
no_reset which does firmware live patching, updating the firmware image
without reset, no downtime and no configuration lose. The driver checks
if the firmware is capable of handling the pending firmware changes as a
live patch. If it is then it triggers firmware live patching flow.

Firmware live patch event notifies the driver that the firmware was just
updated using live patch. In such case the driver should not reload or
re-initiate entities, part to updating the firmware version and
re-initiate the firmware tracer which can be updated by live patch with
new strings database to help debugging an issue.

The enable_remote_dev_reset devlink param flags that the host admin
allows resets by other hosts. In case it is cleared mlx5 host PF driver
will send NACK on pci sync for firmware update reset request and the
command will fail.
By default enable_remote_dev_reset parameter is true, so pci sync for
firmware update reset is enabled.

The enable_remote_dev_reset devlink param flags that the host admin
allows device resets that can be initiated by other hosts. This
parameter is useful for setups where a device is shared by different
hosts, such as multi-host setup. Once the user set this parameter to
false, the driver should NACK any attempt to reset the device while the
driver is loaded.
