As the nla_nest_start() may fail with NULL returned, the return value should be checked. Note that this is not a real bug, nothing will break here. The next nla_put() will fail as well and we'll bail (and nla_nest_cancel() can handle NULL). But we keep getting those "fixes" so whatever. Signed-off-by:

Miquel Raynal says: ==================== Marvell nvmem mac addresses support Now that we are aligned on how to make information available from static storage media to drivers like Ethernet controller drivers or switch drivers by using nvmem cells and going through the whole nvmem infrastructure, here are two driver updates to reflect these changes. Prior to the driver updates, I propose: * Reverting binding changes which should have never been accepted like that. * A conversion of the (old) Prestera and DFX server bindings (optional, can be dropped if not considered necessary). * A better description of the more recent Prestera PCI switch. Please mind that this series cannot break anything since retrieving the MAC address Prestera driver has never worked upstream, because the (ONIE tlv) driver supposed to export the MAC address has not been accepted in its original form and has been updated to the nvmem-layout infrastructure (bindings have been merged, the code remains to be applied). ==================== Link: https://lore.kernel.org/r/20221124111556.264647-1-miquel.raynal@bootlin.comSigned-off-by:

Miquel Raynal authored
The ONIE standard describes the organization of tlv (type-length-value) arrays commonly stored within NVMEM devices on common networking hardware. Several drivers already make use of NVMEM cells for purposes like retrieving a default MAC address provided by the manufacturer. What made ONIE tables unusable so far was the fact that the information where "dynamically" located within the table depending on the manufacturer wishes, while Linux NVMEM support only allowed statically defined NVMEM cells. Fortunately, this limitation was eventually tackled with the introduction of discoverable cells through the use of NVMEM layouts, making it possible to extract and consistently use the content of tables like ONIE's tlv arrays. Parsing this table at runtime in order to get various information is now possible. So, because many Marvell networking switches already follow this standard, let's consider using NVMEM cells as a new valid source of information when looking for a base MAC address, which is one of the primary uses of these new fields. Indeed, manufacturers following the ONIE standard are encouraged to provide a default MAC address there, so let's eventually use it if no other MAC address has been found using the existing methods.

This driver fist makes an expensive DT lookup to retrieve its DT node (this is a PCI driver) in order to later search for the base-mac-provider property. This property has no reality upstream and this code should not have been accepted like this in the first place. Instead, there is a proper nvmem interface that should be used. Let's avoid these extra lookups and rely on the nvmem internal logic. Signed-off-by:

Miquel Raynal authored
Export of_get_mac_addr_nvmem() and rename it to of_get_mac_address_nvmem() in order to fit the convention followed by the existing exported helpers of the same kind. This way, OF compatible drivers using eg. fwnode_get_mac_address() can do a direct call to it instead of calling of_get_mac_address() just for the nvmem step, avoiding to repeat an expensive DT lookup which has already been done once. Eventually, fwnode_get_mac_address() should probably be updated to perform the nvmem lookup directly, but as of today, nvmem cells seem not to be supported by ACPI yet which would defeat this kind of extension.

Even though this description is not used anywhere upstream (no matching driver), while on this file I decided I would try a conversion to yaml in order to clarify the prestera family description. I cannot keep the nodename dfx-server@xxxx so I switched to dfx-bus@xxxx which matches simple-bus.yaml. Otherwise I took the example context from the only user of this compatible: armada-xp-98dx3236.dtsi, which is a rather old and not perfect DT. Signed-off-by:

This reverts commit 40acc052. marvell,prestera.txt is an old file describing the old Alleycat3 standalone switches. The commit mentioned above actually hacked these bindings to add support for a device tree property for a more modern version of the IP connected over PCI, using only the generic compatible in order to retrieve the device node from the prestera driver to read one static property. The problematic property discussed here is "base-mac-provider". The original intent was to point to a nvmem device which could produce the relevant nvmem-cell. This property has never been acked by DT maintainers and fails all the layering that has been brought with the nvmem bindings by pointing at a nvmem producer, bypassing the existing nvmem bindings, rather than a nvmem cell directly. Furthermore, the property cannot even be used upstream because it expected the ONIE tlv driver to produce a specific cell, driver which used nacked bindings and thus was never merged, replaced by a more integrated concept: the nvmem-layout. So let's forget about this temporary addition, safely avoiding the need for any backward compatibility handling. A new (yaml) binding file will be brought with the prestera bindings, and there we will actually include a description of the modern IP over PCI, including the right way to point to a nvmem cell.

The fileserver probing code attempts to work out the best fileserver to use for a volume by retrieving the RTT calculated by AF_RXRPC for the probe call sent to each server and comparing them. Sometimes, however, no RTT estimate is available and rxrpc_kernel_get_srtt() returns false, leading good fileservers to be given an RTT of UINT_MAX and thus causing the rotation algorithm to ignore them. Fix afs_select_fileserver() to ignore rxrpc_kernel_get_srtt()'s return value and just take the estimated RTT it provides - which will be capped at 1 second.
