Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present for any node. Add unevaluatedProperties or additionalProperties as appropriate. Signed-off-by:

Christian Marangi says: ==================== net: stmmac: improve tx timer logic This series comes with the intention of restoring original performance of stmmac on some router/device that used the stmmac driver to handle gigabit traffic. More info are present in patch 3. This cover letter is to show results and improvements of the following change. The move to hr_timer for tx timer and commit 8fce3331 ("net: stmmac: Rework coalesce timer and fix multi-queue races") caused big performance regression on these kind of device. This was observed on ipq806x that after kernel 4.19 couldn't handle gigabit speed anymore. The following series is currently applied and tested in OpenWrt SNAPSHOT and have great performance increase. (the scenario is qca8k switch + stmmac dwmac1000) Some good comparison can be found here [1]. The difference is from a swconfig scenario (where dsa tagging is not used so very low CPU impact in handling traffic) and DSA scenario where tagging is used and there is a minimal impact in the CPU. As can be notice even with DSA in place we have better perf. It was observed by other user that also SQM scenario with cake scheduler were improved in the order of 100mbps (this scenario is CPU limited and any increase of perf is caused by removing load on the CPU) Been at least 15 days that this is in use without any complain or bug reported about queue timeout. (was the case with v1 before the additional patch was added, only appear on real world tests and not on iperf tests) [1] https://forum.openwrt.org/t/netgear-r7800-exploration-ipq8065-qca9984/285/3427?u=ansuel ==================== Link: https://lore.kernel.org/r/20231018123550.27110-1-ansuelsmth@gmail.comSigned-off-by:

Commit 8fce3331 ("net: stmmac: Rework coalesce timer and fix multi-queue races") decreased the TX coalesce timer from 40ms to 1ms. This caused some performance regression on some target (regression was reported at least on ipq806x) in the order of 600mbps dropping from gigabit handling to only 200mbps. The problem was identified in the TX timer getting armed too much time. While this was fixed and improved in another commit, performance can be improved even further by increasing the timer delay a bit moving from 1ms to 5ms. The value is a good balance between battery saving by prevending too much interrupt to be generated and permitting good performance for internet oriented devices. Signed-off-by:

Move TX timer arm call after DMA interrupt is enabled again. The TX timer arm function changed logic and now is skipped if a napi is already scheduled. By moving the TX timer arm call after DMA is enabled, we permit to correctly skip if a DMA interrupt has been fired and a napi has been scheduled again. Signed-off-by:

There is currently a problem with the TX timer getting armed multiple unnecessary times causing big performance regression on some device that suffer from heavy handling of hrtimer rearm. The use of the TX timer is an old implementation that predates the napi implementation and the interrupt enable/disable handling. Due to stmmac being a very old code, the TX timer was never evaluated again with this new implementation and was kept there causing performance regression. The performance regression started to appear with kernel version 4.19 with 8fce3331 ("net: stmmac: Rework coalesce timer and fix multi-queue races") where the timer was reduced to 1ms causing it to be armed 40 times more than before. Decreasing the timer made the problem more present and caused the regression in the other of 600-700mbps on some device (regression where this was notice is ipq806x). The problem is in the fact that handling the hrtimer on some target is expensive and recent kernel made the timer armed much more times. A solution that was proposed was reverting the hrtimer change and use mod_timer but such solution would still hide the real problem in the current implementation. To fix the regression, apply some additional logic and skip arming the timer when not needed. Arm the timer ONLY if a napi is not already scheduled. Running the timer is redundant since the same function (stmmac_tx_clean) will run in the napi TX poll. Also try to cancel any timer if a napi is scheduled to prevent redundant run of TX call. With the following new logic the original performance are restored while keeping using the hrtimer. Signed-off-by:

We currently have napi_if_scheduled_mark_missed that can be used to check if napi is scheduled but that does more thing than simply checking it and return a bool. Some driver already implement custom function to check if napi is scheduled. Drop these custom function and introduce napi_is_scheduled that simply check if napi is scheduled atomically. Update any driver and code that implement a similar check and instead use this new helper. Signed-off-by:

'san_addr' and 'mac_fcoeq' members of struct iavf_mac_info are unused. 'type' is write-only. Delete all three. The function iavf_set_mac_type that sets 'type' also checks if the PCI vendor ID is Intel. This is unnecessary. Delete the whole function. If in the future there's a need for the MAC type (or other PCI ID-dependent data), I would prefer to use .driver_data in iavf_pci_tbl[] for this purpose. Signed-off-by:

Johannes Zink says: ==================== net: stmmac: use correct PPS input indexing The stmmac can have 0 to 4 auxiliary snapshot in channels, which can be used for capturing external triggers with respect to the eqos PTP timer. Previously when enabling the auxiliary snapshot, an invalid request was written to the hardware register, except for the Intel variant of this driver, where the only snapshot available was hardcoded. Patch 1 of this series cleans up the debug netdev_dbg message indicating the auxiliary snapshot being {en,dis}abled. No functional changes here Patch 2 of this series writes the correct PPS input indexing to the hardware registers instead of a previously used fixed value Patch 3 of this series removes a field member from plat_stmmacnet_data that is no longer needed Patch 4 of this series prepares Patch 5 by protecting the snapshot enabled flag by the aux_ts_lock mutex Patch 5 of this series adds a temporary workaround, since at the moment the driver can handle only one single auxiliary snapshot at a time. Previously the driver silently dropped the previous configuration and enabled the new one. Now, if a snapshot is already enabled and userspace tries to enable another without previously disabling the snapshot currently enabled: issue a netdev_err and return an errorcode indicating the device is busy. This series is a "never worked, doesn't hurt anyone" touchup to the PPS capture for non-intel variants of the dwmac driver. ==================== Link: https://lore.kernel.org/r/20231010-stmmac_fix_auxiliary_event_capture-v2-0-51d5f56542d7@pengutronix.deSigned-off-by: -

Even though the hardware theoretically supports up to 4 simultaneous auxiliary snapshot capture channels, the stmmac driver does support only a single channel to be active at a time. Previously in case of a PTP_CLK_REQ_EXTTS request, previously active auxiliary snapshot capture channels were silently dropped and the new channel was activated. Instead of silently changing the state for all consumers, log an error and return -EBUSY if a channel is already in use in order to signal to userspace to disable the currently active channel before enabling another one.

This is a preparation patch. The next patch will check if an external TS is active and return with an error. So we have to move the change of the plat->flags that tracks if external timestamping is enabled after that check. Prepare for this change and move the plat->flags change into the mutex and the if (on). Signed-off-by:

The stmmac supports up to 4 auxiliary snapshots that can be enabled by setting the appropriate bits in the PTP_ACR bitfield. Previously as of commit f4da5652 ("net: stmmac: Add support for external trigger timestamping") instead of setting the bits, a fixed value was written to this bitfield instead of passing the appropriate bitmask. Now the correct bit is set according to the ptp_clock_request.extts_index passed as a parameter to stmmac_enable(). Signed-off-by:

Get ahead of the game and fix all the -Wformat=2 noted warnings in the intel drivers directory. There are one set of i40e and iavf warnings I couldn't figure out how to fix because the driver is already using vsnprintf without an explicit "const char *" format string. Tested with both gcc-12 and clang-15. I found gcc-12 runs clean after this series but clang-15 is a little worried about the vsnprintf lines. summary of warnings: drivers/net/ethernet/intel/fm10k/fm10k_ethtool.c:148:34: warning: format string is not a string literal [-Wformat-nonliteral] drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1416:24: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1416:24: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1421:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1421:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/igc/igc_ethtool.c:776:24: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igc/igc_ethtool.c:776:24: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/igc/igc_ethtool.c:779:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igc/igc_ethtool.c:779:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/iavf/iavf_ethtool.c:199:34: warning: format string is not a string literal [-Wformat-nonliteral] drivers/net/ethernet/intel/igb/igb_ethtool.c:2360:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igb/igb_ethtool.c:2360:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/igb/igb_ethtool.c:2363:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igb/igb_ethtool.c:2363:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/i40e/i40e_ethtool.c:208:34: warning: format string is not a string literal [-Wformat-nonliteral] drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2515:23: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2515:23: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2519:23: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2519:23: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ice/ice_ethtool.c:1064:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ice/ice_ethtool.c:1064:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ice/ice_ethtool.c:1084:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ice/ice_ethtool.c:1084:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ice/ice_ethtool.c:1100:24: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ice/ice_ethtool.c:1100:24: note: treat the string as an argument to avoid this Suggested-by:

device_get_match_data() expects that of_device_id->data points to actual fec_devinfo data, not a platform_device_id entry. Fix this by adjusting OF device data pointers to their corresponding structs. enum imx_fec_type is now unused and can be removed.

Assume that caller's 'to' offset really represents an upper boundary for the pattern search, so patterns extending past this offset are to be rejected. The old behaviour also was kind of inconsistent when it comes to fragmentation (or otherwise non-linear skbs): If the pattern started in between 'to' and 'from' offsets but extended to the next fragment, it was not found if 'to' offset was still within the current fragment. Test the new behaviour in a kselftest using iptables' string match. Suggested-by:

Florian Westphal says: ==================== netfilter next pull request 2023-10-18 This series contains initial netfilter skb drop_reason support, from myself. First few patches fix up a few spots to make sure we won't trip when followup patches embed error numbers in the upper bits (we already do this in some places). Then, nftables and bridge netfilter get converted to call kfree_skb_reason directly to let tooling pinpoint exact location of packet drops, rather than the existing NF_DROP catchall in nf_hook_slow(). I would like to eventually convert all netfilter modules, but as some callers cannot deal with NF_STOLEN (notably act_ct), more preparation work is needed for this. Last patch gets rid of an ugly 'de-const' cast in nftables. ==================== Signed-off-by: -

Paul Greenwalt says: ==================== ethtool: Add link mode maps for forced speeds The following patch set was initially a part of [1]. As the purpose of the original series was to add the support of the new hardware to the intel ice driver, the refactoring of advertised link modes mapping was extracted to a new set. The patch set adds a common mechanism for mapping Ethtool forced speeds with Ethtool supported link modes, which can be used in drivers code. [1] https://lore.kernel.org/netdev/20230823180633.2450617-1-pawel.chmielewski@intel.com Changelog: v4->v5: Separated ethtool and qede changes into two patches, fixed indentation, and moved ethtool_forced_speed_maps_init() from ioctl.c to ethtool.h v3->v4: Moved the macro for setting fields into the common header file v2->v3: Fixed whitespaces, added missing line at end of file v1->v2: Fixed formatting, typo, moved declaration of iterator to loop line. ==================== Signed-off-by:
