Allows to build kernel that supports the arptables mangle target via nftables' compat infra but without the arptables get/setsockopt interface or the old arptables filter interpreter. IOW, setting IP_NF_ARPFILTER=n will break arptables-legacy, but arptables-nft will continue to work as long as nftables compat support is enabled. Signed-off-by:

Allow a new process to take ownership of a previously owned table, useful mostly for firewall management services restarting or suspending when idle. By extending __NFT_TABLE_F_UPDATE, the on/off/on check in nf_tables_updtable() also covers table adoption, although it is actually not needed: Table adoption is irreversible because nf_tables_updtable() rejects attempts to drop NFT_TABLE_F_OWNER so table->nlpid setting can happen just once within the transaction. If the transaction commences, table's nlpid and flags fields are already set and no further action is required. If it aborts, the table returns to orphaned state. Signed-off-by:

This companion flag to NFT_TABLE_F_OWNER requests the kernel to keep the table around after the process has exited. It marks such table as orphaned (by dropping OWNER flag but keeping PERSIST flag in place), which opens it for other processes to manipulate. For the sake of simplicity, PERSIST flag may not be altered though. Signed-off-by:

We had to add another synchronize_rcu() in recent fix. Bite the bullet and add an rcu_head to netdev_name_node, free from RCU. Note that name_node does not hold any reference on dev to which it points, but there must be a synchronize_rcu() on device removal path, so we should be fine. Signed-off-by:

The RENESAS FemtoClock3 Wireless is a high-performance jitter attenuator, frequency translator, and clock synthesizer. The device is comprised of 3 digital PLLs (DPLL) to track CLKIN inputs and three independent low phase noise fractional output dividers (FOD) that output low phase noise clocks. FemtoClock3 supports one Time Synchronization (Time Sync) channel to enable an external processor to control the phase and frequency of the Time Sync channel and to take phase measurements using the TDC. Intended applications are synchronization using the precision time protocol (PTP) and synchronization with 0.5 Hz and 1 Hz signals from GNSS. Signed-off-by:

This change is for the PHC devices that can measure the phase offset between PHC signal and the external signal, such as the 1PPS signal of GNSS. Reporting PTP_CLOCK_EXTOFF to user space will be piggy-backed to the existing ptp_extts_event so that application such as ts2phc can poll the external offset the same way as extts. Hence, ts2phc can use the offset to achieve the alignment between PHC and the external signal by the help of either SW or HW filters. Signed-off-by:

As of now, the field TCA_TAPRIO_ATTR_FLAGS is being validated by manually checking its value, using the function taprio_flags_valid(). With this patch, the field will be validated through the netlink policy NLA_POLICY_MASK, where the mask is defined by TAPRIO_SUPPORTED_FLAGS. The mutual exclusivity of the two flags TCA_TAPRIO_ATTR_FLAG_FULL_OFFLOAD and TCA_TAPRIO_ATTR_FLAG_TXTIME_ASSIST is still checked manually. Changes since RFC: - fixed reversed xmas tree - use NL_SET_ERR_MSG_MOD() for both invalid configuration Changes since v1: - Changed NL_SET_ERR_MSG_MOD to NL_SET_ERR_MSG_ATTR when wrong flags issued - Changed __u32 to u32 Changes since v2: - Added the missing parameter for NL_SET_ERR_MSG_ATTR (sorry again for the noise) Signed-off-by:

In the current interrupt controller, the MAC interrupt acts as the parent interrupt in the GPIO IRQ chip. But when the number of Rx/Tx ring changes, the PCI IRQ vector needs to be reallocated. Then this interrupt controller would be corrupted. So use irq_domain structure to avoid the above problem. Signed-off-by:

Add a note when using esw_port_metadata. The parameter has runtime mode but setting it does not take effect immediately. Setting it must happen in legacy mode, and the port metadata takes effects when the switchdev mode is enabled. Disable eswitch port metadata:: $ devlink dev param set pci/0000:06:00.0 name esw_port_metadata value \ false cmode runtime Change eswitch mode to switchdev mode where after choosing the metadata value:: $ devlink dev eswitch set pci/0000:06:00.0 mode switchdev Note that other mlx5 devlink runtime parameters, esw_multiport and flow_steering_mode, do not have this limitation.

Correct the PHY loopback bit handling in the ksz8_w_phy_bmcr and ksz8_r_phy_bmcr functions for KSZ8794 and KSZ8873 variants in the ksz8795 driver. Previously, the code erroneously used Bit 7 of port register 0xD for both chip variants, which is actually for LED configuration. This update ensures the correct registers and bits are used for the PHY loopback feature: - For KSZ8794: Use 0xF / Bit 7. - For KSZ8873: Use 0xD / Bit 0. The lack of loopback support was seen on KSZ8873 system by using "ethtool -t lanX". After this patch, the ethtool selftest will work, but only if port is not part of a bridge. Signed-off-by:

Christian Marangi says: ==================== net: phy: generic polarity + LED support for qca808x This small series add LEDs support for qca808x. QCA808x apply on PHY reset a strange polarity settings and require some tweak to apply a more common configuration found on devices. On adding support for it, it was pointed out that a similar feature is also being implemented for a marvell PHY where LED polarity is set per LED (and not global) and also have a special mode where the LED is tristated. The first 3 patch are to generalize this as we expect more PHY in the future to have a similar configuration. The implementation is extensible to support additional special mode in the future with minimal changes and don't create regression on already implemented PHY drivers. ==================== Link: https://lore.kernel.org/r/20240125203702.4552-1-ansuelsmth@gmail.comSigned-off-by:

Add LED support for QCA8081 PHY. Documentation for this LEDs PHY is very scarce even with NDA access to Documentation for OEMs. Only the blink pattern are documented and are very confusing most of the time. No documentation is present about forcing the LED on/off or to always blink. Those settings were reversed by poking the regs and trying to find the correct bits to trigger these modes. Some bits mode are not clear and maybe the documentation option are not 100% correct. For the sake of LED support the reversed option are enough to add support for current LED APIs. Supported HW control modes are: - tx - rx - link_10 - link_100 - link_1000 - link_2500 - half_duplex - full_duplex Also add support for LED polarity set to set LED polarity to active high or low. QSDK sets this value to high by default but PHY reset value doesn't have this enabled by default. QSDK also sets 2 additional bits but their usage is not clear, info about this is added in the header. It was verified that for correct function of the LED if active high is needed, only BIT 6 is needed. Signed-off-by:

Add support for PHY LEDs polarity modes. Some PHY require LED to be set to active low to be turned ON. Adds support for this by declaring active-low property in DT. PHY driver needs to declare .led_polarity_set() to configure LED polarity modes. Function will pass the index with the LED index and a bitmap with all the required modes to set. Current supported modes are: - active-low with the flag PHY_LED_ACTIVE_LOW. LED is set to active-low to turn it ON. - inactive-high-impedance with the flag PHY_LED_INACTIVE_HIGH_IMPEDANCE. LED is set to high impedance to turn it OFF. Signed-off-by:
