Subject: [PATCH net-next v12 00/13] net: Make timestamping selectable

Up until now, there was no way to let the user select the hardware
PTP provider at which time stamping occurs. The stack assumed that PHY time
stamping is always preferred, but some MAC/PHY combinations were buggy.

This series updates the default MAC/PHY default timestamping and aims to
allow the user to select the desired hwtstamp provider administratively.

Changes in v12:
- Add missing return description in the kdoc.
- Fix few nit.
- Link to v11: https://lore.kernel.org/r/[email protected]

Changes in v11:
- Add netlink examples.
- Remove a change of my out of tree marvell_ptp patch in the patch series.
- Remove useless extern.
- Link to v10: https://lore.kernel.org/r/[email protected]

Changes in v10:
- Move declarations to net/core/dev.h instead of netdevice.h
- Add netlink documentation.
- Add ETHTOOL_A_TSINFO_GHWTSTAMP netlink attributes instead of a bit in
ETHTOOL_A_TSINFO_TIMESTAMPING bitset.
- Send "Move from simple ida to xarray" patch standalone.
- Add tsinfo ntf command.
- Add rcu_lock protection mechanism to avoid memory leak.
- Fixed doc and kdoc issue.
- Link to v9: https://lore.kernel.org/r/[email protected]

Changes in v9:
- Remove the RFC prefix.
- Correct few NIT fixes.
- Link to v8: https://lore.kernel.org/r/[email protected]

Changes in v8:
- Drop the 6 first patch as they are now merged.
- Change the full implementation to not be based on the hwtstamp layer
(MAC/PHY) but on the hwtstamp provider which mean a ptp clock and a
phc qualifier.
- Made some patch to prepare the new implementation.
- Expand netlink tsinfo instead of a new ts command for new hwtstamp
configuration uAPI and for dumping tsinfo of specific hwtstamp provider.
- Link to v7: https://lore.kernel.org/r/[email protected]

Changes in v7:
- Fix a temporary build error.
- Link to v6: https://lore.kernel.org/r/[email protected]

Changes in v6:
- Few fixes from the reviews.
- Replace the allowlist to default_timestamp flag to know which phy is
using old API behavior.
- Rename the timestamping layer enum values.
- Move to a simple enum instead of the mix between enum and bitfield.
- Update ts_info and ts-set in software timestamping case.

Changes in v5:
- Update to ndo_hwstamp_get/set. This bring several new patches.
- Add few patches to make the glue.
- Convert macb to ndo_hwstamp_get/set.
- Add netlink specs description of new ethtool commands.
- Removed netdev notifier.
- Split the patches that expose the timestamping to userspace to separate
the core and ethtool development.
- Add description of software timestamping.
- Convert PHYs hwtstamp callback to use kernel_hwtstamp_config.

Changes in v4:
- Move on to ethtool netlink instead of ioctl.
- Add a netdev notifier to allow packet trapping by the MAC in case of PHY
time stamping.
- Add a PHY whitelist to not break the old PHY default time-stamping
preference API.

Changes in v3:
- Expose the PTP choice to ethtool instead of sysfs.
You can test it with the ethtool source on branch feature_ptp of:
https://github.com/kmaincent/ethtool
- Added a devicetree binding to select the preferred timestamp.

Changes in v2:
- Move selected_timestamping_layer variable of the concerned patch.
- Use sysfs_streq instead of strmcmp.
- Use the PHY timestamp only if available.

Subject: [PATCH net-next v12 02/13] net: Move dev_set_hwtstamp_phylib to net/core/dev.h

This declaration was added to the header to be called from ethtool.
ethtool is separated from core for code organization but it is not really
a separate entity, it controls very core things.
As ethtool is an internal stuff it is not wise to have it in netdevice.h.
Move the declaration to net/core/dev.h instead.

Remove the EXPORT_SYMBOL_GPL call as ethtool can not be built as a module.

Introduce the description of a hwtstamp provider which is define with a
ptp_clock pointer and a qualifier value.

Add a hwtstamp provider description within the netdev structure to be able
to select the hwtstamp we want too use. By default we use the old API that
does not support hwtstamp selectability which mean the hwtstamp ptp_clock
pointer is unset.

Subject: [PATCH net-next v12 08/13] ptp: Add phc source and helpers to register specific PTP clock or get information

Prepare for future hardware timestamp selection by adding source and
corresponding pointers to ptp_clock structure. Additionally, introduce
helpers for registering specific phydev or netdev PTP clocks, retrieving
PTP clock information such as hwtstamp source or phydev/netdev pointers,
and obtaining the ptp_clock structure from the phc index.

Signed-off-by: Kory Maincent <[email protected]>

Change in v8:
- New patch.

Change in v10:
- Add get and put function to avoid unregistering a ptp clock object used.
- Fix kdoc issues.

Change in v11:
- Remove useless extern.

Change in v12:
- Add missing return description in the kdoc.

Subject: [PATCH net-next v12 07/13] net: Add struct kernel_ethtool_ts_info

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.

Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

[permalink] [raw]
Subject: [PATCH net-next v12 12/13] net: ethtool: tsinfo: Add support for hwtstamp provider and get/set hwtstamp config

Enhance 'get' command to retrieve tsinfo of hwtstamp providers within a
network topology and read current hwtstamp configuration.

Introduce support for ETHTOOL_MSG_TSINFO_SET ethtool netlink socket to
configure hwtstamp of a PHC provider. Note that simultaneous hwtstamp
isn't supported; configuring a new one disables the previous setting.

Also, add support for a specific dump command to retrieve all hwtstamp
providers within the network topology, with added functionality for
filtered dump to target a single interface.

Signed-off-by: Kory Maincent <[email protected]>
---

Pointer attached_dev is used to know if the phy is on the net topology.
This might not be enough and might need Maxime Chevallier link topology
patch series:
https://lore.kernel.org/netdev/[email protected]/

Change in v8:
- New patch

Change in v9:
- Fix nit in done callback.

Change in v10:
- Add documentation.
- Add extack error messages.
- Add NLA_POLICY_* checks.
- Fix few nits.
- Add ETHTOOL_A_TSINFO_GHWTSTAMP netlink attributes instead of a bit in
ETHTOOL_A_TSINFO_TIMESTAMPING bitset.
- Add tsinfo_parse_hwtstamp_provider function for more readability.
- Move netdev_support_hwtstamp_qualifier function in core ptp instead of
core net.
- Add refcount put to release the ptp object.
- Use rcu lock to avoid memory leak.

Change in v12:
- Add missing return description in the kdoc.
- Fix possible leak due to uninitialised variable.
- Add a missing static.

Looks like there's a linking problem starting with patch 9. On a quick
look the functions from a module are now called by build-in code.

Please avoid adding includes to netdevice.h.
IDK if you have more dependencies in later patches but for a pointer
member you don't even need a forward declaration, let alone include.

Hi Kory,

A few lines beyond this hunk, within the "if (hwtstamp)" block,
is the following:

cfg->qualifier = dev->hwtstamp->qualifier;

Now that dev->hwtstamp is managed using RCU, I don't think it is correct
to dereference it directly like this. Rather, the hwtstamp local variable,
which has rcu_dereference'd this pointer should be used:

cfg->qualifier = hwtstamp->qualifier;

Flagged by Sparse.

Perhaps it is not possible, but if the loop iterates zero times then
ret will be used uninitialised here.

Yes indeed, thanks for the report.
