====================
Netfilter fixes for net
The following batch contains one Netfilter fix for net:
1) Fix unaligned atomic read on struct nft_set_ext in nft_set_hash
backend that causes an alignment failure splat on aarch64. This
is related to a recent fix and it has been reported via the
regressions mailing list.

While creating a new monitor in RV, besides generating code from dot2k,
there are a few manual steps which can be tedious and error prone, like
adding the tracepoints, makefile lines and kconfig.
This patch restructures the existing monitors to keep some files in the
monitor's folder itself, which can be automatically generated by future
versions of dot2k.
Monitors have now their own Kconfig and tracepoint snippets. For
simplicity, the main tracepoint definition, is moved to the RV
directory, it defines only the tracepoint classes and includes the
monitor-specific tracepoints, which reside in the monitor directory.
Tracepoints and Kconfig no longer need to be copied and adapted from
existing ones but only need to be included in the main files.
The Makefile remains untouched since there's little advantage in having
a separated Makefile for each monitor with a single line and including
it in the main RV Makefile.

The rendered version of the MPTCP events [1] looked strange, because the
whole content of the 'doc' was displayed in the same block.
It was then not clear that the first words, not even ended by a period,
were the attributes that are defined when such events are emitted. These
attributes have now been moved to the end, prefixed by 'Attributes:' and
ended with a period. Note that '>-' has been added after 'doc:' to allow
':' in the text below.
The documentation in the UAPI header has been auto-generated by:

A previous commit changed overwriting kiocb->ki_flags with
->f_iocb_flags with masking it in. This breaks for retry situations,
where we don't necessarily want to retain previously set flags, like
IOCB_NOWAIT.
The use case needs IOCB_HAS_METADATA to be persistent, but the change
makes all flags persistent, which is an issue. Add a request flag to
track whether the request has metadata or not, as that is persistent
across issues.

This introduces ftrace_get_symaddr() which tries to convert fentry_ip
passed by ftrace or fgraph callback to symaddr without calling
kallsyms API. It returns the symbol address or 0 if it fails to
convert it.

Fprobe store its data structure address and size on the fgraph return stack
by __fprobe_header. But most 64bit architecture can combine those to
one unsigned long value because 4 MSB in the kernel address are the same.
With this encoding, fprobe can consume less space on ret_stack.
This introduces asm/fprobe.h to define arch dependent encode/decode
macros. Note that since fprobe depends on CONFIG_HAVE_FUNCTION_GRAPH_FREGS,
currently only arm64, loongarch, riscv, s390 and x86 are supported.

Rewrite fprobe implementation on function-graph tracer.
Major API changes are:
- 'nr_maxactive' field is deprecated.
- This depends on CONFIG_DYNAMIC_FTRACE_WITH_ARGS or
!CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS, and
CONFIG_HAVE_FUNCTION_GRAPH_FREGS. So currently works only
on x86_64.
- Currently the entry size is limited in 15 * sizeof(long).
- If there is too many fprobe exit handler set on the same
function, it will fail to probe.

Allow fprobe events to be enabled with CONFIG_DYNAMIC_FTRACE_WITH_ARGS.
With this change, fprobe events mostly use ftrace_regs instead of pt_regs.
Note that if the arch doesn't enable HAVE_FTRACE_REGS_HAVING_PT_REGS,
fprobe events will not be able to be used from perf.

Add ftrace_fill_perf_regs() which should be compatible with the
perf_fetch_caller_regs(). In other words, the pt_regs returned from the
ftrace_fill_perf_regs() must satisfy 'user_mode(regs) == false' and can be
used for stack tracing.

Add ftrace_partial_regs() which converts the ftrace_regs to pt_regs.
This is for the eBPF which needs this to keep the same pt_regs interface
to access registers.
Thus when replacing the pt_regs with ftrace_regs in fprobes (which is
used by kprobe_multi eBPF event), this will be used.
If the architecture defines its own ftrace_regs, this copies partial
registers to pt_regs and returns it. If not, ftrace_regs is the same as
pt_regs and ftrace_partial_regs() will return ftrace_regs::regs.

Change the fprobe exit handler to use ftrace_regs structure instead of
pt_regs. This also introduce HAVE_FTRACE_REGS_HAVING_PT_REGS which
means the ftrace_regs is including the pt_regs so that ftrace_regs
can provide pt_regs without memory allocation.
Fprobe introduces a new dependency with that.

Pass ftrace_regs to the fgraph_ops::entryfunc(). If ftrace_regs is not
available, it passes a NULL instead. User callback function can access
some registers (including return address) via this ftrace_regs.
Note that the ftrace_regs can be NULL when the arch does NOT define:
HAVE_DYNAMIC_FTRACE_WITH_ARGS or HAVE_DYNAMIC_FTRACE_WITH_REGS.
More specifically, if HAVE_DYNAMIC_FTRACE_WITH_REGS is defined but
not the HAVE_DYNAMIC_FTRACE_WITH_ARGS, and the ftrace ops used to
register the function callback does not set FTRACE_OPS_FL_SAVE_REGS.
In this case, ftrace_regs can be NULL in user callback.

The logic for invoking __DO_TRACE_CALL was extracted to a static inline
function called __rust_do_trace_##name so that Rust can call it
directly. This logic does not include the static branch, to avoid a
function call when the tracepoint is disabled.
Since the C code needs to perform the same logic after checking the
static key, this logic is currently duplicated. Thus, remove this
duplication by having C call the static inline function too.

The function dyn_event_release() uses argv_split() which must be freed via
argv_free(). It contains several error paths that do a goto out to call
argv_free() for cleanup. This makes the code complex and error prone.
Create a new __free() directive __free(argv_free) that will call
argv_free() for data allocated with argv_split(), and use it in the
dyn_event_release() function.

It is not helpful to error out on some SDCA function types, we
might as well report the correct name and let the driver core
simply not bind a driver to those functions for which the code
lacks support. Also given no functions currently have support,
it seems odd to select some as unsupported.

SDCA only supports 3-bits for the function address, but the ACPI value
is 64-bits. Update the code that parses this to do a bounds check
and error out on invalid addresses. Currently, an invalid address
would truncate to the bottom 3-bits when used and thus use a likely
incorrect address. With the bounds check, it is also now safe to
shrink the size of the adr member of sdca_function_desc to a u8 and
rearrange the struct members to pack better with the new size of adr.

locally. These are included by the point of use through other

should directly include things they directly use, so add the

Currently the dispatching of link status events is implemented by
each RDMA driver independently, and most of them have very similar
patterns. Add support for this in ib_core so that we can get rid
of duplicate codes in each driver.
A new last_port_state is added in ib_port_cache to cache the port
state of the last link status events dispatching. The original
port_state in ib_port_cache is not used here because it will be
updated when ib_dispatch_event() is called, which means it may
be changed between two link status events, and may lead to a loss
of event dispatching.
Some drivers currently have some private stuff in their link status
events handler in addition to event dispatching, and cannot be
perfectly integrated into the ib_core handling process. For these
drivers, add a new ops report_port_event() so that they can keep
their current processing.
Finally, events of LAG devices are not supported yet in this patch
as currently there is no way to obtain ibdev from upper netdev in
ib_core. This can be a TODO work after the core have more support
for LAG.

While RMDO consists of:
* B31..28 Revision Major
* B27..24 Revision Minor
* B23..20 Version Major
* B19..16 Version Minor
* B15..0 Reserved, shall be set to zero.
As per the PD spec ("8.3.3.16.2.1 PR_Give_Revision State"), a request is
only expected when an explicit contract is established and the port is
in ready state. This AMS is only supported for PD >= 3.0.

Commit 265b07df758a ("clk: Provide managed helper to get and enable bulk
clocks") added devm_clk_bulk_get_all_enable() function, but missed to
return the number of clocks stored in the clk_bulk_data table referenced
by the clks argument. Without knowing the number, it's not possible to
iterate these clocks when needed, hence the argument is useless and
could have been simply removed.
A new helper devm_clk_bulk_get_all_enabled() has been introduced, which
is consistent with devm_clk_bulk_get_all() in terms of the returned
value.
Drop the obsolete function since all users switched to the new helper.

In the cited commit, when changing from switchdev to legacy mode,
uplink representor's netdev is kept, and its profile is replaced with
nic profile, so netdev is detached from old profile, then attach to
new profile.
During profile change, the hardware resources allocated by the old
profile will be cleaned up. However, the cleanup is relying on the
related kernel modules. And they may need to flush themselves first,
which is triggered by netdev events, for example, NETDEV_UNREGISTER.
However, netdev is kept, or netdev_register is called after the
cleanup, which may cause troubles because the resources are still
referred by kernel modules.
The same process applies to all the caes when uplink is leaving
switchdev mode, including devlink eswitch mode set legacy, driver
unload and devlink reload. For the first one, it can be blocked and
returns failure to users, whenever possible. But it's hard for the
others. Besides, the attachment to nic profile is unnecessary as the
netdev will be unregistered anyway for such cases.
So in this patch, the original behavior is kept only for devlink
eswitch set mode legacy. For the others, moves netdev unregistration
before the profile change.

Currently mlx5_flow_destination includes counter_id which is assigned in
case we use flow counter on the flow steering rule. However, counter_id
is not enough data in case of using HW Steering. Thus, have mlx5_fc
object as part of mlx5_flow_destination instead of counter_id and assign
it where needed.
In case counter_id is received from user space, create a local counter
object to represent it.

When one is too lazy to use an LSP to conduct look-ups on struct
definitions, one might use the ever useful `struct <name> {` search
string. However this doesn't work with `struct miscdevice {` because
of a stray double space. Assuming that this wasn't intentional, let's
simply remove it.

The bridge input code may drop frames for various reasons and at various
points in the ingress handling logic. Currently kfree_skb() is used
everywhere, and therefore no drop reason is specified. Add drop reasons
to the most common drop points.
Drop reasons are not added exhaustively to the entire bridge code. The
intention is to incrementally add drop reasons to the rest of the bridge
code in follow up patches.
