net: TC protocol all support in Sparx5 IS2 VCAP
This provides support for the TC flower filters 'protocol all' clause in
the Sparx5 IS2 VCAP.
It builds on top of the initial IS2 VCAP support found in these series:
https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/https://lore.kernel.org/all/20221109114116.3612477-1-steen.hegelund@microchip.com/https://lore.kernel.org/all/20221111130519.1459549-1-steen.hegelund@microchip.com/https://lore.kernel.org/all/20221117213114.699375-1-steen.hegelund@microchip.com/
Functionality:
==============
As the configuration for the Sparx5 IS2 VCAP consists of one (or more)
keyset(s) for each lookup/port per traffic classification, it is not
always possible to cover all protocols with just one ordinary VCAP rule.
To improve this situation the driver will try to find out what keysets a
rule will need to cover a TC flower "protocol all" filter and then compare
this set of keysets to what the hardware is currently configured for.
In case multiple keysets are needed then the driver can create a rule per
rule size (e.g. X6 and X12) and use a mask on the keyset type field to
allow the VCAP to match more than one keyset with just one rule.
This is possible because the keysets that have the same size typically has
many keys in common, so the VCAP rule keys can make a common match.
The result is that one TC filter command may create multiple IS2 VCAP rules
of different sizes that have a type field with a masked type id.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- Sparx5 IS0 VCAP support
- TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support
Version History:
================
v2 Fixed a NULL return value compiler warning.
Moved the new vcap_find_actionfield function a bit up in the file.
v1 Initial version

This allows support of TC protocol all for the Sparx5 IS2 VCAP.
This is done by creating multiple rules that covers the rule size and
traffic types in the IS2.
Each rule size (e.g X16 and X6) may have multiple keysets and if there are
more than one the type field in the VCAP rule will be wildcarded to support
these keysets.

Currently, when a FEC device is brought up, the irq coalesce settings
are reset to their default values (1000us, 200 frames). That's
unexpected, and breaks for example use of an appropriate .link file to
make systemd-udev apply the desired

or any other method that would do a one-time setup during early boot.
Refactor the code so that fec_restart() instead uses
fec_enet_itr_coal_set(), which simply applies the settings that are
stored in the private data, and initialize that private data with the

The watchdog timer is used to monitor whether the process
of transmitting data is timeout. If we use qlcnic driver,
the dev_watchdog() that is the timer handler of watchdog

Commit 868f9f2f8e00 ("vfs: fix copy_file_range() regression in cross-fs
copies") removed fallback to generic_copy_file_range() for cross-fs
cases inside vfs_copy_file_range().
To preserve behavior of nfsd and ksmbd server-side-copy, the fallback to
generic_copy_file_range() was added in nfsd and ksmbd code, but that
call is missing sb_start_write(), fsnotify hooks and more.
Ideally, nfsd and ksmbd would pass a flag to vfs_copy_file_range() that
will take care of the fallback, but that code would be subtle and we got
vfs_copy_file_range() logic wrong too many times already.
Instead, add a flag to explicitly request vfs_copy_file_range() to
perform only generic_copy_file_range() and let nfsd and ksmbd use this
flag only in the fallback path.
This choise keeps the logic changes to minimum in the non-nfsd/ksmbd code
paths to reduce the risk of further regressions.

The PTR_TRUSTED flag should only be applied to pointers where the verifier can

The fentry/fexit/fmod_ret programs are not in this category.
Only arguments of SEC("tp_btf") and SEC("iter") programs are trusted
(which have BPF_TRACE_RAW_TP and BPF_TRACE_ITER attach_type correspondingly)

====================
Currently, without rcu attribute info in BTF, the verifier treats
rcu tagged pointer as a normal pointer. This might be a problem
for sleepable program where rcu_read_lock()/unlock() is not available.
For example, for a sleepable fentry program, if rcu protected memory
access is interleaved with a sleepable helper/kfunc, it is possible
the memory access after the sleepable helper/kfunc might be invalid
since the object might have been freed then. Even without
a sleepable helper/kfunc, without rcu_read_lock() protection,
it is possible that the rcu protected object might be release
in the middle of bpf program execution which may cause incorrect
result.
To prevent above cases, enable btf_type_tag("rcu") attributes,
introduce new bpf_rcu_read_lock/unlock() kfuncs and add verifier support.
In the rest of patch set, Patch 1 enabled btf_type_tag for __rcu
attribute. Patche 2 added might_sleep in bpf_func_proto. Patch 3 added new
bpf_rcu_read_lock/unlock() kfuncs and verifier support.
Patch 4 added some tests for these two new kfuncs.
Changelogs:
v9 -> v10:
. if no rcu tag support in vmlinux btf, using bpf_rcu_read_lock/unlock()
will cause verification error.
. at bpf_rcu_read_unlock(), invalidate rcu ptr to PTR_UNTRUSTED
instead of SCALAR_VALUE.
. a few other comment changes and other minor changes.
v8 -> v9:
. remove sleepable prog check for ld_abs/ind checking in rcu read
lock region.
. fix a test failure with gcc-compiled kernel.
. a couple of other minor fixes.
v7 -> v8:
. add might_sleep in bpf_func_proto so we can easily identify whether
a helper is sleepable or not.
. do not enforce rcu rules for sleepable, e.g., rcu dereference must
be in a bpf_rcu_read_lock region. This is to keep old code working
fine.
. Mark 'b' in 'b = a->b' (b is tagged with __rcu) as MEM_RCU only if
'b = a->b' in rcu read region and 'a' is trusted. This adds safety
guarantee for 'b' inside the rcu read region.
v6 -> v7:
. rebase on top of bpf-next.
. remove the patch which enables sleepable program using
cgrp_local_storage map. This is orthogonal to this patch set
and will be addressed separately.
. mark the rcu pointer dereference result as UNTRUSTED if inside
a bpf_rcu_read_lock() region.
v5 -> v6:
. fix selftest prog miss_unlock which tested nested locking.
. add comments in selftest prog cgrp_succ to explain how to handle
nested memory access after rcu memory load.
v4 -> v5:
. add new test to aarch64 deny list.
v3 -> v4:
. fix selftest failures when built with gcc. gcc doesn't support
btf_type_tag yet and some tests relies on that. skip these
tests if vmlinux BTF does not have btf_type_tag("rcu").
v2 -> v3:
. went back to MEM_RCU approach with invalidate rcu ptr registers
at bpf_rcu_read_unlock() place.
. remove KF_RCU_LOCK/UNLOCK flag and compare btf_id at verification
time instead.
v1 -> v2:
. use kfunc instead of helper for bpf_rcu_read_lock/unlock.
. not use MEM_RCU bpf_type_flag, instead use active_rcu_lock
in reg state to identify rcu ptr's.
. Add more self tests.
. add new test to s390x deny list.

Add two kfunc's bpf_rcu_read_lock() and bpf_rcu_read_unlock(). These two kfunc's
can be used for all program types. The following is an example about how
rcu pointer are used w.r.t. bpf_rcu_read_lock()/bpf_rcu_read_unlock().
struct task_struct {
...
struct task_struct *last_wakee;
struct task_struct __rcu *real_parent;
...
};
Let us say prog does 'task = bpf_get_current_task_btf()' to get a
'task' pointer. The basic rules are:
- 'real_parent = task->real_parent' should be inside bpf_rcu_read_lock
region. This is to simulate rcu_dereference() operation. The
'real_parent' is marked as MEM_RCU only if (1). task->real_parent is
inside bpf_rcu_read_lock region, and (2). task is a trusted ptr. So
MEM_RCU marked ptr can be 'trusted' inside the bpf_rcu_read_lock region.
- 'last_wakee = real_parent->last_wakee' should be inside bpf_rcu_read_lock
region since it tries to access rcu protected memory.
- the ptr 'last_wakee' will be marked as PTR_UNTRUSTED since in general
it is not clear whether the object pointed by 'last_wakee' is valid or
not even inside bpf_rcu_read_lock region.
The verifier will reset all rcu pointer register states to untrusted
at bpf_rcu_read_unlock() kfunc call site, so any such rcu pointer
won't be trusted any more outside the bpf_rcu_read_lock() region.
The current implementation does not support nested rcu read lock
region in the prog.

There are a bunch of late fixes that just came in, in particular
a longer series for Rockchips devicetree files, but most of those
just address cosmetic errors that were found during the binding
validation.
There are a couple of code changes:
- A regression fix to the IXP42x PCI bus
- A fix for a memory leak on optee, and another one for mach-mxs
- Two fixes for the sunxi rsb bus driver, to address
problems with the shutdown logic
The rest are small but important devicetree fixes for a number of
individual boards, addressing issues across all platforms:
- arm global timer on older rockchip SoCs is unstable and
needs to be disabled in favor of a more reliable clocksource
- Corrections to fix bluetooth, mmc, and networking on
a few Rockchip boards
- at91/sam9g20ek UDC needs a pin controller config change
- an omap board runs into mmc probe errors because of regulator
nodes in the wrong place
- imx8mp-evk has a minor inaccuracy with its pin config,
but without user visible impact
- The Allwinner H6 Hantro G2 video decoder needs an IOMMU
reference to prevent the driver from crashing

Pull ARM SoC fixes from Arnd Bergmann:
"There are a bunch of late fixes that just came in, in particular a
longer series for Rockchips devicetree files, but most of those just
address cosmetic errors that were found during the binding validation.
There are a couple of code changes:
- A regression fix to the IXP42x PCI bus
- A fix for a memory leak on optee, and another one for mach-mxs
- Two fixes for the sunxi rsb bus driver, to address problems with
the shutdown logic
The rest are small but important devicetree fixes for a number of
individual boards, addressing issues across all platforms:
- arm global timer on older rockchip SoCs is unstable and needs to be
disabled in favor of a more reliable clocksource
- Corrections to fix bluetooth, mmc, and networking on a few Rockchip
boards
- at91/sam9g20ek UDC needs a pin controller config change
- an omap board runs into mmc probe errors because of regulator nodes
in the wrong place
- imx8mp-evk has a minor inaccuracy with its pin config, but without
user visible impact
- The Allwinner H6 Hantro G2 video decoder needs an IOMMU reference
to prevent the driver from crashing"

Validate that the IEEE80211_P2P_ATTR_CHANNEL_LIST attribute contains
enough space for a 'struct wilc_attr_oper_ch'. If the attribute is too
small then it can trigger an out-of-bounds write later in the function.
'struct wilc_attr_oper_ch' is variable sized so also check 'attr_len'
does not extend beyond the end of 'buf'.

Microchip USB Analyzer can activate the internal termination resistors
by setting the "termination" option ON, or OFF to to deactivate them.
As I've observed, both with my oscilloscope and captured USB packets
below, you must send "0" to turn it ON, and "1" to turn it OFF.
From the schematics in the user's guide, I can confirm that you must
drive the CAN_RES signal LOW "0" to activate the resistors.
Reverse the argument value of usb_msg.termination to fix this.
These are the two commands sequence, ON then OFF.
