2023-10-13net: fec: replace deprecated strncpy with ethtool_sprintfJustin Stitt1-4/+2
`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. ethtool_sprintf() is designed specifically for get_strings() usage. Let's replace strncpy in favor of this more robust and easier to understand interface. Also, while we're here, let's change memcpy() over to ethtool_sprintf() for consistency.

2023-09-07net: enetc: distinguish error from valid pointers in enetc_fixup_clear_rss_rfs()Vladimir Oltean1-1/+1
enetc_psi_create() returns an ERR_PTR() or a valid station interface pointer, but checking for the non-NULL quality of the return code blurs that difference away. So if enetc_psi_create() fails, we call enetc_psi_destroy() when we shouldn't. This will likely result in crashes, since enetc_psi_create() cleans up everything after itself when it returns an ERR_PTR().

git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull modules updates from Luis Chamberlain: "Summary of the changes worth highlighting from most interesting to boring below: - Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the protection he put in place in year 2020 to prevent proprietary modules from using GPL only symbols, and also ensuring proprietary modules which export symbols grandfather their taint. That was done through year 2020 commit 262e6ae7081d ("modules: inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by clarifing __symbol_get() was only ever intended to prevent module reference loops by Linux kernel modules and so making it only find symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic used by Nvidia was to use symbol_get() to purposely swift through proprietary module symbols and completely bypass our traditional EXPORT_SYMBOL*() annotations and community agreed upon restrictions. A small set of preamble patches fix up a few symbols which just needed adjusting for this on two modules, the rtc ds1685 and the networking enetc module. Two other modules just needed some build fixing and removal of use of __symbol_get() as they can't ever be modular, as was done by Arnd on the ARM pxa module and Christoph did on the mmc au1xmmc driver. This is a good reminder to us that symbol_get() is just a hack to address things which should be fixed through Kconfig at build time as was done in the later patches, and so ultimately it should just go. - Extremely late minor fix for old module layout 055f23b74b20 ("module: check for exit sections in layout_sections() instead of module_init_section()") by James Morse for arm64. Note that this layout thing is old, it is *not* Song Liu's commit ac3b43283923 ("module: replace module_layout with module_memory"). The issue however is very odd to run into and so there was no hurry to get this in fast. - Although the fix did not go through the modules tree I'd like to highlight the fix by Peter Zijlstra in commit 54097309620e ("x86/static_call: Fix __static_call_fixup()") now merged in your tree which came out of what was originally suspected to be a fallout of the the newer module layout changes by Song Liu commit ac3b43283923 ("module: replace module_layout with module_memory") instead of module_init_section()"). Thanks to the report by Christian Bricart and the debugging by Song Liu & Peter that turned to be noted as a kernel regression in place since v5.19 through commit ee88d363d156 ("x86,static_call: Use alternative RET encoding"). I highlight this to reflect and clarify that we haven't seen more fallout from ac3b43283923 ("module: replace module_layout with module_memory"). - RISC-V toolchain got mapping symbol support which prefix symbols with "$" to help with alignment considerations for disassembly. This is used to differentiate between incompatible instruction encodings when disassembling. RISC-V just matches what ARM/AARCH64 did for alignment considerations and Palmer Dabbelt extended is_mapping_symbol() to accept these symbols for RISC-V. We already had support for this for all architectures but it also checked for the second character, the RISC-V check Dabbelt added was just for the "$". After a bit of testing and fallout on linux-next and based on feedback from Masahiro Yamada it was decided to simplify the check and treat the first char "$" as unique for all architectures, and so we no make is_mapping_symbol() for all archs if the symbol starts with "$". The most relevant commit for this for RISC-V on binutils was: https://sourceware.org/pipermail/binutils/2021-July/117350.html - A late fix by Andrea Righi (today) to make module zstd decompression use vmalloc() instead of kmalloc() to account for large compressed modules. I suspect we'll see similar things for other decompression algorithms soon. - samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and Chen Jiahao" * tag 'modules-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module/decompress: use vmalloc() for zstd decompression workspace kallsyms: Add more debug output for selftest ARM: module: Use module_init_layout_section() to spot init sections arm64: module: Use module_init_layout_section() to spot init sections module: Expose module_init_layout_section() modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules rtc: ds1685: use EXPORT_SYMBOL_GPL for ds1685_rtc_poweroff net: enetc: use EXPORT_SYMBOL_GPL for enetc_phc_index mmc: au1xmmc: force non-modular build and remove symbol_get usage ARM: pxa: remove use of symbol_get() samples/hw_breakpoint: mark sample_hbp as static samples/hw_breakpoint: fix building without module unloading samples/hw_breakpoint: Fix kernel BUG 'invalid opcode: 0000' modpost, kallsyms: Treat add '$'-prefixed symbols as mapping symbols kernel: params: Remove unnecessary ‘0’ values from err module: Ignore RISC-V mapping symbols too
2023-08-25net: fec: add statistics for XDP_TXWei Fang1-1/+4
The FEC driver supports the statistics for XDP actions except for XDP_TX before, because the XDP_TX was not supported when adding the statistics for XDP. Now the FEC driver has supported XDP_TX since commit f601899e4321 ("net: fec: add XDP_TX feature support"). So it's reasonable and necessary to add statistics for XDP_TX.

2023-08-16net: fec: improve XDP_TX performanceWei Fang2-70/+75
As suggested by Jesper and Alexander, we can avoid converting xdp_buff to xdp_frame in case of XDP_TX to save a bunch of CPU cycles, so that we can further improve the XDP_TX performance. Before this patch on i.MX8MP-EVK board, the performance shows as follows. root@imx8mpevk:~# ./xdp2 eth0 proto 17: 353918 pkt/s proto 17: 352923 pkt/s proto 17: 353900 pkt/s proto 17: 352672 pkt/s proto 17: 353912 pkt/s proto 17: 354219 pkt/s After applying this patch, the performance is improved. root@imx8mpevk:~# ./xdp2 eth0 proto 17: 369261 pkt/s proto 17: 369267 pkt/s proto 17: 369206 pkt/s proto 17: 369214 pkt/s proto 17: 369126 pkt/s proto 17: 369272 pkt/s Signed-off-by: Wei Fang <[email protected]> Suggested-by: Alexander Lobakin <[email protected]> Suggested-by: Jesper Dangaard Brouer <[email protected]> Reviewed-by: Jesper Dangaard Brouer <[email protected]> Signed-off-by: David S.

2023-08-16net: fec: add XDP_TX feature supportWei Fang2-21/+87
The XDP_TX feature is not supported before, and all the frames which are deemed to do XDP_TX action actually do the XDP_DROP action. So this patch adds the XDP_TX support to FEC driver. I tested the performance of XDP_TX in XDP_DRV mode and XDP_SKB mode respectively on i.MX8MP-EVK platform, and as suggested by Jesper, I also tested the performance of XDP_REDIRECT on the same platform. And the test steps and results are as follows. XDP_TX test: Step 1: One board is used as generator and connects to switch,and the FEC port of DUT also connects to the switch. Both boards with flow control off. Then the generator runs the pktgen_sample03_burst_single_flow.sh script to generate and send burst traffic to DUT. Note that the size of packet was set to 64 bytes and the procotol of packet was UDP in my test scenario. In addition, the SMAC of the packet need to be different from the MAC of the generator, because the xdp2 program will swap the DMAC and SMAC of the packet and send it back to the generator. If the SMAC of the generated packet is the MAC of the generator, the generator will receive the returned traffic which increase the CPU loading and significantly degrade the transmit speed of the generator, and finally it affects the test of XDP_TX performance. Step 2: The DUT runs the xdp2 program to transmit received UDP packets back out on the same port where they were received. root@imx8mpevk:~# ./xdp2 eth0 proto 17: 353918 pkt/s proto 17: 352923 pkt/s proto 17: 353900 pkt/s proto 17: 352672 pkt/s proto 17: 353912 pkt/s proto 17: 354219 pkt/s root@imx8mpevk:~# ./xdp2 -S eth0 proto 17: 160604 pkt/s proto 17: 160708 pkt/s proto 17: 160564 pkt/s proto 17: 160684 pkt/s proto 17: 160640 pkt/s proto 17: 160720 pkt/s The above results show that the XDP_TX performance of XDP_DRV mode is much better than XDP_SKB mode, more than twice that of XDP_SKB mode, which is in line with our expectation. XDP_REDIRECT test: Step1: Both the generator and the FEC port of the DUT connet to the switch port. All the ports with flow control off, then the generator runs the pktgen script to generate and send burst traffic to DUT. Note that the size of packet was set to 64 bytes and the procotol of packet was UDP in my test scenario. Step2: The DUT runs the xdp_redirect program to redirect the traffic from the FEC port to the FEC port itself. root@imx8mpevk:~# ./xdp_redirect eth0 eth0 Redirecting from eth0 (ifindex 2; driver fec) to eth0 (ifindex 2; driver fec) Summary 232,302 rx/s 0 err,drop/s 232,344 xmit/s Summary 234,579 rx/s 0 err,drop/s 234,577 xmit/s Summary 235,548 rx/s 0 err,drop/s 235,549 xmit/s Summary 234,704 rx/s 0 err,drop/s 234,703 xmit/s Summary 235,504 rx/s 0 err,drop/s 235,504 xmit/s Summary 235,223 rx/s 0 err,drop/s 235,224 xmit/s Summary 234,509 rx/s 0 err,drop/s 234,507 xmit/s Summary 235,481 rx/s 0 err,drop/s 235,482 xmit/s Summary 234,684 rx/s 0 err,drop/s 234,683 xmit/s Summary 235,520 rx/s 0 err,drop/s 235,520 xmit/s Summary 235,461 rx/s 0 err,drop/s 235,461 xmit/s Summary 234,627 rx/s 0 err,drop/s 234,627 xmit/s Summary 235,611 rx/s 0 err,drop/s 235,611 xmit/s Packets received : 3,053,753 Average packets/s : 234,904 Packets transmitted : 3,053,792 Average transmit/s : 234,907 Compared the performance of XDP_TX with XDP_REDIRECT, XDP_TX is also much better than XDP_REDIRECT.

The workaround implemented in commit 3222b5b613db ("net: enetc: initialize RFS/RSS memories for unused ports too") is no longer effective after commit 6fffbc7ae137 ("PCI: Honor firmware's device disabled status"). Thus, it has introduced a regression and we see AER errors being reported again: $ ip link set sw2p0 up && dhclient -i sw2p0 && ip addr show sw2p0 fsl_enetc 0000:00:00.2 eno2: configuring for fixed/internal link mode fsl_enetc 0000:00:00.2 eno2: Link is Up - 2.5Gbps/Full - flow control rx/tx mscc_felix 0000:00:00.5 swp2: configuring for fixed/sgmii link mode mscc_felix 0000:00:00.5 swp2: Link is Up - 1Gbps/Full - flow control off sja1105 spi2.2 sw2p0: configuring for phy/rgmii-id link mode sja1105 spi2.2 sw2p0: Link is Up - 1Gbps/Full - flow control off pcieport 0000:00:1f.0: AER: Multiple Corrected error received: 0000:00:00.0 pcieport 0000:00:1f.0: AER: can't find device of ID0000 Rob's suggestion is to reimplement the enetc driver workaround as a PCI fixup, and to modify the PCI core to run the fixups for all PCI functions. This change handles the first part. We refactor the common code in enetc_psi_create() and enetc_psi_destroy(), and use the PCI fixup only for those functions for which enetc_pf_probe() won't get called. This avoids some work being done twice for the PFs which are enabled.

2023-08-02net: remove phy_has_hwtstamp() -> phy_mii_ioctl() decision from converted ↵Vladimir Oltean1-8/+0
drivers It is desirable that the new .ndo_hwtstamp_set() API gives more uniformity, less overhead and future flexibility w.r.t. the PHY timestamping behavior. Currently there are some drivers which allow PHY timestamping through the procedure mentioned in Documentation/networking/timestamping.rst. They don't do anything locally if phy_has_hwtstamp() is set, except for lan966x which installs PTP packet traps. Centralize that behavior in a new dev_set_hwtstamp_phylib() code function, which calls either phy_mii_ioctl() for the phylib PHY, or .ndo_hwtstamp_set() of the netdev, based on a single policy (currently simplistic: phy_has_hwtstamp()). Any driver converted to .ndo_hwtstamp_set() will automatically opt into the centralized phylib timestamping policy. Unconverted drivers still get to choose whether they let the PHY handle timestamping or not. Netdev drivers with integrated PHY drivers that don't use phylib presumably don't set dev->phydev, and those will always see HWTSTAMP_SOURCE_NETDEV requests even when converted. The timestamping policy will remain 100% up to them.

2023-08-02net: fec: delete fec_ptp_disable_hwts()Vladimir Oltean3-17/+1
Commit 340746398b67 ("net: fec: fix hardware time stamping by external devices") was overly cautious with calling fec_ptp_disable_hwts() when cmd == SIOCSHWTSTAMP and use_fec_hwts == false, because use_fec_hwts is based on a runtime invariant (phy_has_hwtstamp()). Thus, if use_fec_hwts is false, then fep->hwts_tx_en and fep->hwts_rx_en cannot be changed at runtime; their values depend on the initial memory allocation, which already sets them to zeroes. If the core will ever gain support for switching timestamping layers, it will arrange for a more organized calling convention and disable timestamping in the previous layer as a first step. This means that the code in the FEC driver is not necessary in any case. The purpose of this change is to arrange the phy_has_hwtstamp() code in a way in which it can be refactored away into generic logic.

As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h.

And this event will cause the reset of the FEC hardware. To avoid timeout in this case, we use the txq_trans_cond_update() interface to update txq->trans_start to jiffies so that watchdog won't generate a transmit timeout warning.
