2025-03-20ptp: ocp: reject unsupported periodic output flagsJacob Keller
The ptp_ocp_signal_from_perout() function supports PTP_PEROUT_DUTY_CYCLE and PTP_PEROUT_PHASE. It does not support PTP_PEROUT_ONE_SHOT, but does not reject a request with such an unsupported flag. Add the appropriate check to ensure that unsupported requests are rejected both for PTP_PEROUT_ONE_SHOT as well as any future flags.

2025-03-20broadcom: fix supported flag check in periodic output functionJacob Keller
In bcm_ptp_perout_locked, the driver rejects requests which have PTP_PEROUT_PHASE set. This appears to be an attempt to reject any unsupported flags. Unfortunately, this only checks one flag, but does not protect against PTP_PEROUT_ONE_SHOT, or any future flags which may be added. Fix the check to ensure that no flag other than the supported PTP_PEROUT_DUTY_CYCLE is set.

2025-03-20net: lan743x: reject unsupported external timestamp requestsJacob Keller
The lan743x_ptp_io_event_cap_en() function checks that the given request sets only one of PTP_RISING_EDGE or PTP_FALLING_EDGE, but not both. However, this driver does not check whether other flags (such as PTP_EXT_OFF) are set, nor whether any future unrecognized flags are set. Fix this by adding the appropriate check to the lan743x_ptp_io_extts() function.

2025-03-20renesas: reject PTP_STRICT_FLAGS as unsupportedJacob Keller
The ravb_ptp_extts() function checks the flags coming from the PTP_EXTTS_REQUEST ioctl, to ensure that future flags are not accepted on accident. This was updated to 'honor' the PTP_STRICT_FLAGS in commit 6138e687c7b6 ("ptp: Introduce strict checking of external time stamp options."). However, the driver does not *actually* validate the flags. I originally fixed this driver to reject future flags in commit 592025a03b34 ("renesas: reject unsupported external timestamp flags"). It is still unclear whether this hardware timestamps the rising, falling, or both edges of the input signal. Accepting requests with PTP_STRICT_FLAGS is a bug, as this could lead to users mistakenly assuming a request with PTP_RISING_EDGE actually timestamps the rising edge only. Reject requests with PTP_STRICT_FLAGS (and hence all PTP_EXTTS_REQUEST2 requests) until someone with access to the datasheet or hardware knowledge can confirm the timestamping behavior and update this driver.

2025-03-20igb: reject invalid external timestamp requests for 82580-based HWJacob Keller
The igb_ptp_feature_enable_82580 function correctly checks that unknown flags are not passed to the function. However, it does not actually check PTP_RISING_EDGE or PTP_FALLING_EDGE when configuring the external timestamp function. The data sheet for the 82580 product says: Upon a change in the input level of one of the SDP pins that was configured to detect Time stamp events using the TSSDP register, a time stamp of the system time is captured into one of the two auxiliary time stamp registers (AUXSTMPL/H0 or AUXSTMPL/H1). For example to define timestamping of events in the AUXSTMPL0 and AUXSTMPH0 registers, Software should: 1. Set the TSSDP.AUX0_SDP_SEL field to select the SDP pin that detects the level change and set the TSSDP.AUX0_TS_SDP_EN bit to 1. 2. Set the TSAUXC.EN_TS0 bit to 1 to enable timestamping The same paragraph is in the i350 and i354 data sheets. The wording implies that the time stamps are captured at any level change. There does not appear to be any way to only timestamp one edge of the signal. Reject requests which do not set both PTP_RISING_EDGE and PTP_FALLING_EDGE when operating under PTP_STRICT_FLAGS mode via PTP_EXTTS_REQUEST2.

2025-03-20Merge branch 'support-loopback-mode-speed-selection'Paolo Abeni
Gerhard Engleder says: ==================== Support loopback mode speed selection Previously to commit 6ff3cddc365b ("net: phylib: do not disable autoneg for fixed speeds >= 1G") it was possible to select the speed of the loopback mode by configuring a fixed speed before enabling the loopback mode. Now autoneg is always enabled for >= 1G and a fixed speed of >= 1G requires successful autoneg. Thus, the speed of the loopback mode depends on the link partner for >= 1G. There is no technical reason to depend on the link partner for loopback mode. With this behavior the loopback mode is less useful for testing. Allow PHYs to support optional speed selection for the loopback mode. This support is implemented for the generic loopback support and for PHY drivers, which obviously support speed selection for loopback mode. Additionally, loopback support according to the data sheet is added to the KSZ9031 PHY. Extend phy_loopback() to signal link up and down if speed changes, because a new link speed requires link up signalling. Use this loopback speed selection in the tsnep driver to select the loopback mode speed depending the previously active speed. User space tests with 100 Mbps and 1 Gbps loopback are possible again. ==================== Link: https://patch.msgid.link/20250312203010.47429-1-gerhard@engleder-embedded.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2025-03-19netconsole: allow selection of egress interface via MAC addressUday Shankar
Currently, netconsole has two methods of configuration - module parameter and configfs. The former interface allows for netconsole activation earlier during boot (by specifying the module parameter on the kernel command line), so it is preferred for debugging issues which arise before userspace is up/the configfs interface can be used. The module parameter syntax requires specifying the egress interface name. This requirement makes it hard to use for a couple reasons: - The egress interface name can be hard or impossible to predict. For example, installing a new network card in a system can change the interface names assigned by the kernel. - When constructing the module parameter, one may have trouble determining the original (kernel-assigned) name of the interface (which is the name that should be given to netconsole) if some stable interface naming scheme is in effect. A human can usually look at kernel logs to determine the original name, but this is very painful if automation is constructing the parameter. For these reasons, allow selection of the egress interface via MAC address when configuring netconsole using the module parameter. Update the netconsole documentation with an example of the new syntax. Selection of egress interface by MAC address via configfs is far less interesting (since when this interface can be used, one should be able to easily convert between MAC address and interface name), so it is left unimplemented.

Russell King says: ==================== net: stmmac: deprecate "snps,en-tx-lpi-clockgating" property This series deprecates the "snps,en-tx-lpi-clockgating" property for stmmac. MII Transmit clock gating, where the MAC hardware supports gating this clock, is a function of the connected PHY capabilities, which it reports through its status register. GMAC versions that support transmit clock gating twiddle the LPITCSE bit accordingly in the LPI control/status register, which is handled by the GMAC core specific code. So, "snps,en-tx-lpi-clockgating" not something that is a GMAC property, but is a work-around for phylib not providing an interface to determine whether the PHY allows the transmit clock to be disabled. This series converts the two SoCs that make use of this property (which, I hasten to add, is set in the SoC code) to use the PHY capability bit instead of a DT property, then removes the DT property from the .dtsi, deprecates it in the snps,dwmac binding, and finally in the stmmac code. I am expecting some discussion on how to merge this, as I think the order in which these changes is made is important - we don't want to deprecate the old way until the new code has landed. ==================== Link: https://patch.msgid.link/Z9FVHEf3uUqtKzyt@shell.armlinux.org.uk Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2025-03-19net: stmmac: deprecate "snps,en-tx-lpi-clockgating" propertyRussell King (Oracle)
Whether the MII transmit clock can be stopped is primarily a property of the PHY (there is a capability bit that should be checked first.) Whether the MAC is capable of stopping the transmit clock is a separate issue, but this is already handled by the core DesignWare MAC code. Therefore, snps,en-tx-lpi-clockgating is technically incorrect, and this commit adds a warning should a DT be encountered with the property present. However, we keep backwards compatibility.
