DG1 has 4 DPLLs where DPLL0 and DPLL1 drive DDIA/B and
DPLL2 and DPLL3 drive DDI-TC1/DDI-TC2.
Introduce DG1_DPLL_CFCRx() helper macros to configure

The skus guarded by IS_CNL_WITH_PORT_F() have port F and thus they need
those power wells. The others don't have those. Up to now we were
just overriding the number of power wells on !IS_CNL_WITH_PORT_F(),
relying on those power wells to be the last ones. Now that we have logic
in place to skip power wells by id, use it instead.

While iterating over child nodes with the for_each functions, if
control is transferred from the middle of the loop, as in the case
of a break or return or goto, there is no decrement in the
reference counter thus ultimately resulting in a memory leak.
Add this script to detect potential memory leaks caused by
the absence of of_node_put() before break, goto, or, return
statements which transfer control outside the loop.

To add support for Sparx5, the dependency on MSCC_OCELOT was removed.
However, this increases exposure of the driver question not only to
Sparx5 platforms, but to everyone. Hence re-add the dependency on
MSCC_OCELOT, and extend it with ARCH_SPARX5, to prevent asking the user
about this driver when configuring a kernel without Ocelot and Sparx5
support.

The tcp_hdr_options test adds a "::eB9F" addr to the lo dev.
However, this non loopback address will have a race on ipv6 dad
which may lead to EADDRNOTAVAIL error from time to time.
Even nodad is used in the iproute2 command, there is still a race in
when the route will be added. This will then lead to ENETUNREACH from
time to time.
To avoid the above, this patch uses the default loopback address "::1"
to do the test.

include/linux/rcupdate.h:632:9: sparse: sparse: context imbalance in 'sock_map_seq_start' - wrong count at exit
Add the necessary __acquires and __release annotations to make the
iterator locking schema palatable to sparse. Also add __must_hold

The kernel codebase uses both __acquires(rcu) and __acquires(RCU).
I couldn't find any guidance which one is preferred, so I used

nftables payload statements are used to mangle SCTP headers, but they can
only replace the Internet Checksum. As a consequence, nftables rules that
mangle sport/dport/vtag in SCTP headers potentially generate packets that
are discarded by the receiver, unless the CRC-32C is "offloaded" (e.g the
rule mangles a skb having 'ip_summed' equal to 'CHECKSUM_PARTIAL'.
Fix this extending uAPI definitions and L4 checksum update function, in a
way that userspace programs (e.g. nft) can instruct the kernel to compute
CRC-32C in SCTP headers. Also ensure that LIBCRC32C is built if NF_TABLES
is 'y' or 'm' in the kernel build configuration.

Commit 4fc427e051 ("ipv6_route_seq_next should increase position index")
tried to fix the issue where seq_file pos is not increased
if a NULL element is returned with seq_ops->next(). See bug
https://bugzilla.kernel.org/show_bug.cgi?id=206283
The commit effectively does:
- increase pos for all seq_ops->start()
- increase pos for all seq_ops->next()
For ipv6_route, increasing pos for all seq_ops->next() is correct.
But increasing pos for seq_ops->start() is not correct
since pos is used to determine how many items to skip during
seq_ops->start():
iter->skip = *pos;
seq_ops->start() just fetches the *current* pos item.
The item can be skipped only after seq_ops->show() which essentially
is the beginning of seq_ops->next().
For example, I have 7 ipv6 route entries,

In the above, I specify buffer size 4096, so all records can be returned
to user space with a single trip to the kernel.
If I use buffer size 128, since each record size is 149, internally
kernel seq_read() will read 149 into its internal buffer and return the data
to user space in two read() syscalls. Then user read() syscall will trigger
next seq_ops->start(). Since the current implementation increased pos even
for seq_ops->start(), it will skip record #2, #4 and #6, assuming the first
record is #1.

To fix the problem, create a fake pos pointer so seq_ops->start()
won't actually increase seq_file pos. With this fix, the
above `dd` command with `bs=128` will show correct result.

net/smc: fixes 2020-10-14
The first patch fixes a possible use-after-free of delayed llc events.
Patch 2 corrects the number of DMB buffer sizes. And patch 3 ensures
a correctly formatted return code when smc_ism_register_dmb() fails to
create a new DMB.

smc_ism_register_dmb() returns error codes set by the ISM driver which
are not guaranteed to be negative or in the errno range. Such values
would not be handled by ERR_PTR() and finally the return code will be
used as a memory address.
Fix that by using a valid negative errno value with ERR_PTR().

The SMCD_DMBE_SIZES should include all valid DMBE buffer sizes, so the

When a delayed event is enqueued then the event worker will send this
event the next time it is running and no other flow is currently
active. The event handler is called for the delayed event, and the
pointer to the event keeps set in lgr->delayed_event. This pointer is
cleared later in the processing by smc_llc_flow_start().
This can lead to a use-after-free condition when the processing does not
reach smc_llc_flow_start(), but frees the event because of an error
situation. Then the delayed_event pointer is still set but the event is
freed.
Fix this by always clearing the delayed event pointer when the event is
provided to the event handler for processing, and remove the code to
clear it in smc_llc_flow_start().
