Add net.vrf.strict_mode sysctl parameter. When net.vrf.strict_mode=0 (default) it is possible to associate multiple VRF devices to the same table. Conversely, when net.vrf.strict_mode=1 a table can be associated to a single VRF device. When switching from net.vrf.strict_mode=0 to net.vrf.strict_mode=1, a check is performed to verify that all tables have at most one VRF associated, otherwise the switch is not allowed. The net.vrf.strict_mode parameter is per network namespace. Signed-off-by:

Add the data structures and the processing logic to keep track of the associations between VRF devices and routing tables. When a VRF is instantiated, it needs to refer to a given routing table. For each table, we explicitly keep track of the existing VRFs that refer to the table. Signed-off-by:

Add infrastructure to l3mdev (the core code for Layer 3 master devices) in order to find out the corresponding VRF device for a given table id. Therefore, the l3mdev implementations: - can register a callback that returns the device index of the l3mdev associated with a given table id; - can offer the lookup function (table to VRF device).

Russell King says: ==================== Clause 45 PHY probing improvements Last time this series was posted back in May, Florian reviewed the patches, which was the only feedback I received. I'm now posting them without the RFC tag. This series aims to improve the probing for Clause 45 PHYs. The first four patches clean up get_phy_device() and called functions, updating the kernel doc, adding information about the various error return values. We then provide better kerneldoc for get_phy_device(), describing what is going on, and more importantly what the various return codes mean. Patch 6 adds support for probing MMDs >= 8 to check for their presence. Patch 7 changes get_phy_c45_ids() to only set the returned devices_in_package if we successfully find a PHY. Patch 8 splits the use of "devices in package" from the "mmds present". Patch 9 expands our ID reading to cover the other MMDs. ==================== Signed-off-by: -
Russell King authored
Expand the device_ids[] array to allow all MMD IDs to be read rather than just the first 8 MMDs, but only read the ID if the MDIO_STAT2 register reports that a device really is present here for these new devices to maintain compatibility with our current behaviour. Note that only a limited number of devices have MDIO_STAT2. 88X3310 PHY vendor MMDs do are marked as present in the devices_in_package, but do not contain IEE 802.3 compatible register sets in their lower space. This avoids reading incorrect values as MMD identifiers. Reviewed-by:

We have two competing requirements for the devices_in_package field. We want to use it as a bit array indicating which MMDs are present, but we also want to know if the Clause 22 registers are present. Since "devices in package" is a term used in the 802.3 specification, keep this as the as-specified values read from the PHY, and introduce a new member "mmds_present" to indicate which MMDs are actually present in the PHY, derived from the "devices in package" value.

Only set the devices_in_package to a non-zero value if we find a valid value for this field, so we avoid leaving it set to e.g. 0x1fffffff. Reviewed-by:

Add support for probing MMDs above 7 for a valid devices-in-package specifier, but only probe the vendor MMDs for this if they also report that there the device is present in status register 2. This avoids issues where the MMD is implemented, but does not provide IEEE 802.3 compliant registers (such as the MV88X3310 PHY.) Reviewed-by:

Reword the get_phy_device() kerneldoc to be more explicit about how we probe for the PHY, and what the various return conditions signify. Reviewed-by:

Move the ID check from get_phy_device() into get_phy_c22_id(), which simplifies get_phy_device(). The ID reading functions are now responsible for indicating whether they found a PHY or not via their return code - they must return -ENODEV when a PHY is not present. Reviewed-by:
-
Russell King authored
When we decide that a PHY is not present, we do not need to go through the hoops of setting *phy_id to 0xffffffff, and then return zero to make get_phy_device() fail - we can return -ENODEV which will have the same effect. Doing so means we no longer have to pass a pointer to phy_id in, and we can then clean up the clause 22 path in a similar way. Reviewed-by:

Russell King authored
Rearrange the code to read the PHY IDs, so we don't call get_phy_id() only to immediately call get_phy_c45_ids(). Move that logic into get_phy_device(), which results in better readability. Reviewed-by:

Move the Cortina PHY workaround out of the "devices in package" loop; it doesn't need to be in there as the control flow will terminate the loop once we enter the workaround irrespective of the workaround's outcome. The workaround is triggered by the ID being mostly 1's, which will in any case terminate the loop. Signed-off-by:

Eric Dumazet says: ==================== net: tso: expand to UDP support With QUIC getting more attention these days, it is worth implementing UDP direct segmentation, the same we did for TCP.
