Nikolay Aleksandrov says: ==================== net: bridge: fdb activity tracking This set adds extensions needed for EVPN multi-homing proper and efficient mac sync. User-space (e.g. FRR) needs to be able to track non-dynamic entry activity on per-fdb basis depending if a tracked fdb is currently peer active or locally active and needs to be able to add new peer active fdb (static + track + inactive) without refreshing it to get real activity tracking. Patch 02 adds a new NDA attribute - NDA_FDB_EXT_ATTRS to avoid future pollution of NDA attributes by bridge or vxlan. New bridge/vxlan specific fdb attributes are embedded in NDA_FDB_EXT_ATTRS, which is used in patch 03 to pass the new NFEA_ACTIVITY_NOTIFY attribute which controls if an fdb should be tracked and also reflects its current state when dumping. It is treated as a bitfield, current valid bits are: 1 - mark an entry for activity tracking 2 - mark an entry as inactive to avoid multiple notifications and reflect state properly Patch 04 adds the ability to avoid refreshing an entry when changing it via the NFEA_DONT_REFRESH flag. That allows user-space to mark a static entry for tracking and keep its real activity unchanged. The set has been extensively tested with FRR and those changes will be upstreamed if/after it gets accepted. ==================== Signed-off-by:

When we modify or create a new fdb entry sometimes we want to avoid refreshing its activity in order to track it properly. One example is when a mac is received from EVPN multi-homing peer by FRR, which doesn't want to change local activity accounting. It makes it static and sets a flag to track its activity.

This patch adds the ability to notify about activity of any entries (static, permanent or ext_learn). EVPN multihoming peers need it to properly and efficiently handle mac sync (peer active/locally active). We add a new NFEA_ACTIVITY_NOTIFY attribute which is used to dump the current activity state and to control if static entries should be monitored at all. We use 2 bits - one to activate fdb entry tracking (disabled by default) and the second to denote that an entry is inactive. We need the second bit in order to avoid multiple notifications of inactivity. Obviously this makes no difference for dynamic entries since at the time of inactivity they get deleted, while the tracked non-dynamic entries get the inactive bit set and get a notification.

Add an attribute to NDA which will contain all future fdb-specific attributes in order to avoid polluting the NDA namespace with e.g. bridge or vxlan specific attributes. The attribute is called NDA_FDB_EXT_ATTRS and the structure would look like: [NDA_FDB_EXT_ATTRS] = { [NFEA_xxx] } Signed-off-by:

Antoine Tenart says: ==================== net: phy: mscc: PHC and timestamping support This series aims at adding support for PHC and timestamping operations in the MSCC PHY driver, for the VSC858x and VSC8575. Those PHYs are capable of timestamping in 1-step and 2-step for both L2 and L4 traffic. As of this series, only IPv4 support was implemented when using L4 mode. This is because of an hardware limitation which prevents us for supporting both IPv4 and IPv6 at the same time. Implementing support for IPv6 should be quite easy (I do have the modifications needed for the hardware configuration) but I did not see a way to retrieve this information in hwtstamp(). What would you suggest? Those PHYs are distributed in hardware packages containing multiple times the PHY. The VSC8584 for example is composed of 4 PHYs. With hardware packages, parts of the logic is usually common and one of the PHY has to be used for some parts of the initialization. Following this logic, the 1588 blocks of those PHYs are shared between two PHYs and accessing the registers has to be done using the "base" PHY of the group. This is handled thanks to helpers in the PTP code (and locks). We also need the MDIO bus lock while performing a single read or write to the 1588 registers as the read/write are composed of multiple MDIO transactions (and we don't want other threads updating the page). To get and set the PHC time, a GPIO has to be used and changes are only retrieved or committed when on a rising edge. The same GPIO is shared by all PHYs, so the granularity of the lock protecting it has to be different from the ones protecting the 1588 registers (the VSC8584 PHY has 2 1588 blocks, and a single load/save pin). Patch 1 extends the recently added helpers to share information between PHYs of the same hardware package; to allow having part of the probe to be shared (in addition to the already supported init part). This will be used when adding support for PHC/TS to initialize locks. Patches 2 and 3 are mostly cosmetic. Patch 4 takes into account the 1588 block in the MACsec initialization, to allow having both the MACsec and 1588 blocks initialized on a running system. Patches 5 and 6 add support for PHC and timestamping operations in the MSCC driver. An initialization of the 1588 block (plus all the registers definition; and helpers) is added first; and then comes a patch to implement the PHC and timestamping API. Patches 7 and 8 add the required hardware description for device trees, to be able to use the load/save GPIO pin on the PCB120 board. To use this on a PCB120 board, two other series are needed and have already been sent upstream (one is merged). There are no dependency between all those series. Since v3: - Fixed a SKB leak. - Removed ts_lock from the init, as TS and PHC operations aren't registered at this time. - Refectored the ts_base_addr/phy intialization. - Cleaned up the ingr/egr latencies definitons. - Fixed a comment about locking and the shared GPIO. - A few cosmetic fixes. Since v2: - Removed explicit inlines from .c files. - Fixed three warnings. Since v1: - Removed checks in rxtstamp/txtstamp as skb cannot be NULL here. - Reworked get_ptp_header_rx/get_ptp_header. - Reworked the locking logic between the PHC and timestamping operations. - Fixed a compilation issue on x86 reported by Jakub. ==================== Signed-off-by:

Shared PHYs (PHYs in the same hardware package) may have shared registers and their drivers would usually need to share information. There is currently a way to have a shared (part of the) init, by using phy_package_init_once().

Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add new rxtimestamp.sh wrapper script, so that the test runs isolated from background traffic in a private network namespace. Also ignore failures of test case #6 by default. This case verifies that a receive timestamp is not reported if timestamp reporting is enabled for a socket, but generation is disabled. Receive timestamp generation has to be enabled globally, as no associated socket is known yet. A background process that enables rx timestamp generation therefore causes a false positive. Ntpd is one example that does. Add a "--strict" option to cause failure in the event that any test case fails, including test #6. This is useful for environments that are known to not have such background processes. Tested: make -C tools/testing/selftests TARGETS="net" run_tests Signed-off-by:

The mdiobus_scan logic is currently hardcoded to only work with c22 devices. This works fairly well in most cases, but its possible that a c45 device doesn't respond despite being a standard phy. If the parent hardware is capable, it makes sense to scan for c22 devices before falling back to c45. As we want this to reflect the capabilities of the STA, lets add a field to the mii_bus structure to represent the capability. That way devices can opt into the extended scanning. Existing users should continue to default to c22 only scanning as long as they are zero'ing the structure before use. Signed-off-by:

Earlier, .resume() was invoking pci_enable_device(). Drivers should not call PCI legacy helper functions, hence, it was removed. This should not change the behavior of the device as this function is called by PCI core if somehow pm_ops is not able to bind with the driver, else, required tasks are managed by the core itself.

With legacy PM hooks, it was the responsibility of a driver to manage PCI states and also the device's power state. The generic approach is to let the PCI core handle the work. The legacy suspend() and resume() were making use of pci_read/write_config_dword() to enable/disable wol. Driver editing configuration registers of a device is not recommended.
