of_get_child_by_name() gives us an OF node with an elevated refcount, which should be dropped when we're done with it. This is so that, if (of_node_check_flag(node, OF_DYNAMIC)) is true, the node's memory can eventually be freed. There are 2 distinct paths to be considered in qca8k_mdio_register(): - devm_of_mdiobus_register() succeeds: since commit 3b73a7b8 ("net: mdio_bus: add refcounting for fwnodes to mdiobus"), the MDIO core treats this well. - devm_of_mdiobus_register() or anything up to that point fails: it is the duty of the qca8k driver to release the OF node. This change addresses the second case by making sure that the OF node reference is not leaked. The "mdio" node may be NULL, but of_node_put(NULL) is safe. Signed-off-by:

If the "lantiq,xrx200-mdio" child has status = "disabled", the MDIO bus creation should be avoided. Use of_device_is_available() to check for that, and take advantage of 2 facts: - of_device_is_available(NULL) returns false - of_node_put(NULL) is a no-op Signed-off-by:

This driver does not need any of the functionalities that make ds->user_mii_bus special. Those use cases are listed here: https://lore.kernel.org/netdev/20231221174746.hylsmr3f7g5byrsi@skbuf/ It just makes use of ds->user_mii_bus only as storage for its own MDIO bus, which otherwise has no connection to the framework. This is because: - the gswip driver only probes on OF: it fails if of_device_get_match_data() returns NULL - when the child OF node of the MDIO bus is absent, no MDIO bus is registered at all, not even by the DSA framework. In order for that to have happened, the gswip driver would have needed to provide ->phy_read() and ->phy_write() in struct dsa_switch_ops, which it does not. We can break the connection between the gswip driver and the DSA framework and still preserve the same functionality. Since commit 3b73a7b8 ("net: mdio_bus: add refcounting for fwnodes to mdiobus"), MDIO buses take ownership of the OF node handled to them, and release it on their own. The gswip driver no longer needs to do this. Combine that with devres, and we no longer need to keep track of anything for teardown purposes. Signed-off-by:

Inserting the device to block xarray in qdisc_create() is not suitable place to do this. As it requires use of tcf_block() callback, it causes multiple issues. It is called for all qdisc types, which is incorrect. So, instead, move it to more suitable place, which is tcf_block_get_ext() and make sure it is only done for qdiscs that use block infrastructure and also only for blocks which are shared. Symmetrically, alter the cleanup path, move the xarray entry removal into tcf_block_put_ext(). Fixes: 913b47d3 ("net/sched: Introduce tc block netdev tracking infra") Reported-by:

Commit 688eb819 ("x86/csum: Improve performance of `csum_partial`") ended up improving the code generation for the IP csum calculations, and in particular special-casing the 40-byte case that is a hot case for IPv6 headers. It then had _another_ special case for the 64-byte unrolled loop, which did two chains of 32-byte blocks, which allows modern CPU's to improve performance by doing the chains in parallel thanks to renaming the carry flag. This just unifies the special cases and combines them into just one single helper the 40-byte csum case, and replaces the 64-byte case by a 80-byte case that just does that single helper twice. It avoids having all these different versions of inline assembly, and actually improved performance further in my tests. There was never anything magical about the 64-byte unrolled case, even though it happens to be a common size (and typically is the cacheline size). Signed-off-by:

The special case for odd aligned buffers is unnecessary and mostly just adds overhead. Aligned buffers is the expectations, and even for unaligned buffer, the only case that was helped is if the buffer was 1-byte from word aligned which is ~1/7 of the cases. Overall it seems highly unlikely to be worth to extra branch. It was left in the previous perf improvement patch because I was erroneously comparing the exact output of `csum_partial(...)`, but really we only need `csum_fold(csum_partial(...))` to match so its safe to remove. All csum kunit tests pass. Signed-off-by:

Thanks to the recent improvements it was possible to discover nearby devices, it is now also possible to associate with them to form a sub-network using a specific PAN ID. The support includes several functions, such as: * Requesting an association to a coordinator, waiting for the response * Sending a disassociation notification to a coordinator * Receiving an association request when we are coordinator, answering the request (for now all devices are accepted up to a limit, to be refined) * Sending a disassociation notification to a child * Users may request the list of associated devices (the parent and the children). Here are a few example of userspace calls that can be made: # iwpan dev <dev> associate pan_id 2 coord $COORD # iwpan dev <dev> list_associations # iwpan dev <dev> disassociate ext_addr $COORD There are as well two patches from Uwe turning remove callbacks into void functions. * tag 'ieee802154-for-net-next-2023-12-20' of gitolite.kernel.org:pub/scm/linux/kernel/git/wpan/wpan-next: mac802154: Avoid new associations while disassociating ieee802154: Avoid confusing changes after associating mac802154: Only allow PAN controllers to process association requests mac802154: Use the PAN coordinator parameter when stamping packets mac80254: Provide real PAN coordinator info in beacons ieee802154: Give the user the association list mac802154: Handle disassociation notifications from peers mac802154: Follow the number of associated devices ieee802154: Add support for limiting the number of associated devices mac802154: Handle association requests from peers mac802154: Handle disassociations ieee802154: Add support for user disassociation requests mac802154: Handle associating ieee802154: Add support for user association requests ieee802154: Internal PAN management ieee802154: Let PAN IDs be reset ieee802154: hwsim: Convert to platform remove callback returning void ieee802154: fakelb: Convert to platform remove callback returning void ==================== Link: https://lore.kernel.org/r/20231220095556.4d9cef91@xps-13Signed-off-by:

This reverts commit b28ff7a7. The commit introduced P2SB device scan and resource cache during the boot process to avoid deadlock. But it caused detection failure of IDE controllers on old systems [1]. The IDE controllers on old systems and P2SB devices on newer systems have same PCI DEVFN. It is suspected the confusion between those two is the failure cause. Revert the change at this moment until the proper solution gets ready.

Luiz Angelo Daros de Luca reports that the MDIO bus code maintains a reference to the DT node, but does not hold a refcount on the node. The simple solution to this is to add the necessary refcounting into the MDIO bus code for all users, ensuring that on registration, the refcount is incremented, and only dropped when the MDIO bus is released. Do this for fwnodes, so we not only fix this for DT, but also other types of firmware nodes as well. Reported-by:

CSR.OPS bits specify the current operating mode and (according to documentation) they are updated by HW when the operating mode change request is processed. To comply with this check CSR.OPS before proceeding. Commit introduces ravb_set_opmode() that does all the necessities for setting the operating mode (set CCC.OPC (and CCC.GAC, CCC.CSEL, if any) and wait for CSR.OPS) and call it where needed. This should comply with all the HW manuals requirements as different manual variants specify that different modes need to be checked in CSR.OPS when setting CCC.OPC. If gPTP active in config mode is supported and it needs to be enabled, the CCC.GAC and CCC.CSEL needs to be configured along with CCC.OPC in the same write access. For this, ravb_set_opmode() allows passing GAC and CSEL as part of opmode and the function updates accordingly CCC register. Fixes: c156633f ("Renesas Ethernet AVB driver proper") Signed-off-by:

t-queue Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2024-01-02 (ice) This series contains updates to ice driver only. Karol adds support for capable devices to receive timestamp via interrupt rather than polling to allow for less delay. Andrii adds support switchdev hardware packet mirroring. Jake reworks VF rebuild to avoid destroying objects that do not need to be. Jan S removes reporting of rx_len_errors as they are incorrectly reported by hardware. Jan G adds const modifier to some uses that are applicable. Kunwu Chan adds some checks for failed memory allocations. ==================== Signed-off-by: -

During QoS scheduling testing with multiple strict priority flows, the netdev tx watchdog timeout routine is invoked when a low priority QoS queue doesn't get a chance to transmit the packets because other high priority flows are completely subscribing the transmit link. The netdev tx watchdog timeout routine will stop MAC RX and TX functionality in otx2_stop() routine before cleanup of HW TX queues which results in SMQ flush errors because the packets belonging to low priority queues will never gets flushed since MAC TX is disabled. This patch fixes the issue by re-enabling MAC TX to ensure the packets in HW pipeline gets flushed properly. Fixes: a7faa68b ("octeontx2-af: Start/Stop traffic in CGX along with NPC") Signed-off-by:
