We want to remove our use of skb_mac_header() in tx paths, eg remove skb_reset_mac_header() from __dev_queue_xmit(). Idea is that ndo_start_xmit() can get the mac header simply looking at skb->data. Signed-off-by:

Russell King says: ==================== Remove phylink_state's an_enabled member Now that all the fixes and correctness patches have been merged, it is time to switch the two users that make use of .an_enabled to check the Autoneg bit in the advertising mask, and finally remove the .an_enabled member. The first two patches remove the last uses of .an_enabled, which are in DPAA2 and XPCS. The final patch removes the member. ==================== Link: https://lore.kernel.org/r/ZBnT6yW9UY1sAsiy@shell.armlinux.org.ukSigned-off-by:

The Autoneg bit in the advertising bitmap and state->an_enabled are always identical. Thus, we will be removing state->an_enabled. Use the Autoneg bit in the advertising bitmap to indicate whether autonegotiation should be used, rather than using the an_enabled member which will be going away. Signed-off-by:

When requesting a TX queue at a given index, warn on out-of-bounds referencing if the index is greater than the allocated number of queues. Specifically, since this function is used heavily in the networking stack use DEBUG_NET_WARN_ON_ONCE to avoid executing a new branch on every packet. Signed-off-by:

When setting the XPS value of a TX queue, warn the user once if the index of the queue is greater than the number of allocated TX queues. Previously, this scenario went uncaught. In the best case, it resulted in unnecessary allocations. In the worst case, it resulted in out-of-bounds memory references through calls to `netdev_get_tx_queue( dev, index)`. Therefore, it is important to inform the user but not worth returning an error and risk downing the netdevice. Signed-off-by:

Siddharth Vadapalli says: ==================== Add CPSWxG SGMII support for J7200 and J721E This series adds support to configure the CPSW Ethernet Switch in SGMII mode, using the am65-cpsw-nuss driver. SGMII mode is supported by the CPSWxG instances on TI's J7200 and J721E SoCs. Thus, SGMII mode is added in the list of extra_modes for the appropriate compatibles corresponding to the aforementioned SoCs. Additionally, the method of setting the supported interface via struct "phylink_config" is simplified by converting the IF/ELSE statements to SWITCH statements. ==================== Link: https://lore.kernel.org/r/20230321111958.2800005-1-s-vadapalli@ti.comSigned-off-by:

Currently driver performs software based frequency adjustments when RTC capability is not discovered or when in shared PHC mode. But there may be some old firmware versions that still support hardware freq adjustments without RTC capability being exposed. In this situation driver will use non-realtime mode even on single host NICs. Hence enforce software frequency adjustments only when running in shared PHC mode. Make suitable changes for cyclecounter for the same. Signed-off-by:

Driver uses the flag BNXT_FLAG_MULTI_HOST to determine whether to use non-realtime mode PHC when running on a multi host NIC. However when ptp initializes on a NIC with shared PHC, we still don't have this flag set yet because HWRM_FUNC_QCFG is issued much later. Move the ptp initialization code after we have issued func_qcfg. The next patch will use the BNXT_FLAG_MULTI_HOST flag during PTP initialization. Signed-off-by:

When compound pages are enabled, although the mm layer still returns an array of page pointers, a subset (or all) of them may have the same page head since a max 180kb skb can span 2 hugepages if it is on the boundary, be a mix of pages and 1 hugepage, or fit completely in a hugepage. Instead of referencing page head on all page pointers, use page length arithmetic to only call page head when referencing a known different page head to avoid touching a cold cacheline. Tested: See next patch with changes to tcp_mmap Correntess: On a pair of separate hosts as send with MSG_ZEROCOPY will force a copy on tx if using loopback alone, check that the SHA on the message sent is equivalent to checksum on the message received, since the current program already checks for the length. echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages ./tcp_mmap -s -z ./tcp_mmap -H $DADDR -z SHA256 is correct received 2 MB (100 % mmap'ed) in 0.005914 s, 2.83686 Gbit cpu usage user:0.001984 sys:0.000963, 1473.5 usec per MB, 10 c-switches Performance: Run neper between adjacent hosts with the same config tcp_stream -Z --skip-rx-copy -6 -T 20 -F 1000 --stime-use-proc --test-length=30 Before patch: stime_end=37.670000 After patch: stime_end=30.310000 Signed-off-by:

When the CPTS clock is synced/adjusted by running linuxptp (ptp4l/phc2sys), it will cause the TSN EST schedule to drift away over time. This is because the schedule is driven by the EstF periodic counter whose pulse length is defined in ref_clk cycles and it does not automatically sync to CPTS clock. _______ _| ^ expected cycle start time boundary _______________ _|_|___|_| ^ EstF drifted away -> direction To fix it, the same PPM adjustment has to be applied to EstF as done to the PHC CPTS clock, in order to correct the TSN EST cycle length and keep them in sync.

With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A warning in clang aims to catch these at compile time, which reveals: drivers/net/ethernet/pasemi/pasemi_mac.c:1665:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict] .ndo_start_xmit = pasemi_mac_start_tx, ^~~~~~~~~~~~~~~~~~~ 1 error generated. ->ndo_start_xmit() in 'struct net_device_ops' expects a return type of 'netdev_tx_t', not 'int'. Adjust the return type of pasemi_mac_start_tx() to match the prototype's to resolve the warning. While PowerPC does not currently implement support for kCFI, it could in the future, which means this warning becomes a fatal CFI failure at run time.
