Introduce levels of matching on headers of offloaded flows (none, L2, L3, L4) that follow the inline mode levels. This is pre-step for us to offload flows without any matches on headers. Signed-off-by:

Set the initial value to none instead of L2, and set to L2 where the previous initial value was assumed. Make sure to parse L2 matches before L3 matches and L3 before L4. This is a pre-step to get the match level for more purposes other than the validating the needed vs. actual inline level. Signed-off-by:

Currently, when the rule is not to be exclusively executed by the hardware, extack is not passed along and offloading failures don't get logged. The idea was that hardware failures are okay because the rule will get executed in software then and this way it doesn't confuse unware users. But this is not helpful in case one needs to understand why a certain rule failed to get offloaded. Considering it may have been a temporary failure, like resources exceeded or so, reproducing it later and knowing that it is triggering the same reason may be challenging. The ultimate goal is to improve Open vSwitch debuggability when using flower offloading. This patch adds a new flag to enable verbose logging. With the flag set, extack will be passed to the driver, which will be able to log the error. As the operation itself probably won't fail (not because of this, at least), current iproute will already log it as a Warning. The flag is generic, so it can be reused later. No need to restrict it just for HW offloading. The command line will follow the syntax that tc-ebpf already uses, tc ... [ verbose ] ... , and extend its meaning. For example: # ./tc qdisc add dev p7p1 ingress # ./tc filter add dev p7p1 parent ffff: protocol ip prio 1 \ flower verbose \ src_mac ed:13:db:00:00:00 dst_mac 01:80:c2:00:00:d0 \ src_ip 56.0.0.0 dst_ip 55.0.0.0 action drop Warning: TC offload is disabled on net device. # echo $? 0 # ./tc filter add dev p7p1 parent ffff: protocol ip prio 1 \ flower \ src_mac ff:13:db:00:00:00 dst_mac 01:80:c2:00:00:d0 \ src_ip 56.0.0.0 dst_ip 55.0.0.0 action drop # echo $? 0 Signed-off-by:

Chen-Yu Tsai says: ==================== net: stmmac: dwmac-sun8i: Support R40 This is a resend of the patches for net-next split out from my R40 Ethernet support v2 series, as requested by David Miller. The arm-soc bits will follow, once I rework the A64 system controller compatible. Patches 1, 2, and 3 clean up the dwmac-sun8i binding. Patch 4 adds device tree binding for Allwinner R40's Ethernet controller. Patch 5 converts regmap access of the syscon region in the dwmac-sun8i driver to regmap_field, in anticipation of different field widths on the R40. Patch 6 introduces custom plumbing in the dwmac-sun8i driver to fetch a regmap from another device, by looking up said device via a phandle, then getting the regmap associated with that device. Patch 7 adds support for different or absent TX/RX delay chain ranges to the dwmac-sun8i driver. Patch 8 adds support for the R40's ethernet controller. Excerpt from original cover letter: Changes since v1: - Default to fetching regmap from device pointed to by syscon phandle, and falling back to syscon API if that fails. - Dropped .syscon_from_dev field in device data as a result of the previous change. - Added a large comment block explaining the first change. - Simplified description of syscon property in sun8i-dwmac binding. - Regmap now only exposes the EMAC/GMAC register, but retains the offset within its address space. - Added patches for A64, which reuse the same sun8i-dwmac changes. This series adds support for the DWMAC based Ethernet controller found on the Allwinner R40 SoC. The controller is either a DWMAC clone or DWMAC core with its registers rearranged. This is already supported by the dwmac-sun8i driver. The glue layer control registers, unlike other sun8i family SoCs, is not in the system controller region, but in the clock control unit, like with the older A20 and A31 SoCs. While we reuse the bindings for dwmac-sun8i using a syscon phandle reference, we need some custom plumbing for the clock driver to export a regmap that only allows access to the GMAC register to the dwmac-sun8i driver. An alternative would be to allow drivers to register custom syscon devices with their own regmap and locking. ==================== Signed-off-by:

The Allwinner R40 SoC has the EMAC controller supported by dwmac-sun8i. It is named "GMAC", while EMAC refers to the 10/100 Mbps Ethernet controller supported by sun4i-emac. The controller is the same, but the R40 has the glue layer controls in the clock control unit (CCU), with a reduced RX delay chain, and no TX delay chain. This patch adds support for it using the framework laid out by previous patches to map the differences. Signed-off-by:

On the R40 SoC, the RX delay chain only has a range of 0~7 (hundred picoseconds), instead of 0~31. Also the TX delay chain is completely absent. This patch adds support for different ranges by adding per-compatible maximum values in the variant data. A maximum of 0 indicates that the delay chain is not supported or absent. Signed-off-by:

On the Allwinner R40 SoC, the "GMAC clock" register is in the CCU address space. Using a standard syscon to access it provides no coordination with the CCU driver for register access. Neither does it prevent this and other drivers from accessing other, maybe critical, clock control registers. On other SoCs, the register is in the "system control" address space, which might also contain controls for mapping SRAM to devices or the CPU. This hardware has the same issues. Instead, for these types of setups, we let the device containing the control register create a regmap tied to it. We can then get the device from the existing syscon phandle, and retrieve the regmap with dev_get_regmap(). Signed-off-by:

On the Allwinner R40, the "GMAC clock" register is located in the CCU block, at a different register address than the other SoCs that have it in the "system control" block. This patch converts the use of regmap to regmap_field for mapping and accessing the syscon register, so we can have the register address in the variants data, and not in the actual register manipulation code. This patch only converts regmap_read() and regmap_write() calls to regmap_field_read() and regmap_field_write() calls. There are some places where it might make sense to switch to regmap_field_update_bits(), but this is not done here to keep the patch simple. Signed-off-by:

The syscon property is used to point to the device that holds the glue layer control register known as the "EMAC (or GMAC) clock register". We do not need to explicitly list what compatible strings are needed, as this information is readily available in the user manuals. Also the "syscon" device type is more of an implementation detail. There are many ways to access a register not in a device's address range, the syscon interface being the most generic and unrestricted one. Simplify the description so that it says what it is supposed to describe. Signed-off-by:

The clock delay chains found in the glue layer for dwmac-sun8i are only used with RGMII PHYs. They are not intended for non-RGMII PHYs, such as MII external PHYs or the internal PHY. Also, a recent SoC has a smaller range of possible values for the delay chain. This patch reformats the delay chain section of the device tree binding to make it clear that the delay chains only apply to RGMII PHYs, and make it easier to add the R40-specific bits later.

Rahul Lakkireddy says: ==================== kernel: add support to collect hardware logs in crash recovery kernel On production servers running variety of workloads over time, kernel panic can happen sporadically after days or even months. It is important to collect as much debug logs as possible to root cause and fix the problem, that may not be easy to reproduce. Snapshot of underlying hardware/firmware state (like register dump, firmware logs, adapter memory, etc.), at the time of kernel panic will be very helpful while debugging the culprit device driver. This series of patches add new generic framework that enable device drivers to collect device specific snapshot of the hardware/firmware state of the underlying device in the crash recovery kernel. In crash recovery kernel, the collected logs are added as elf notes to /proc/vmcore, which is copied by user space scripts for post-analysis. The sequence of actions done by device drivers to append their device specific hardware/firmware logs to /proc/vmcore are as follows: 1. During probe (before hardware is initialized), device drivers register to the vmcore module (via vmcore_add_device_dump()), with callback function, along with buffer size and log name needed for firmware/hardware log collection. 2. vmcore module allocates the buffer with requested size. It adds an elf note and invokes the device driver's registered callback function. 3. Device driver collects all hardware/firmware logs into the buffer and returns control back to vmcore module. The device specific hardware/firmware logs can be seen as elf notes with note type 0x700, as shown below: Displaying notes found at file offset 0x00001000 with length 0x040032c0: Owner Data size Description LINUX 0x02000fec Unknown note type: (0x00000700) LINUX 0x02000fec Unknown note type: (0x00000700) CORE 0x00000150 NT_PRSTATUS (prstatus structure) CORE 0x00000150 NT_PRSTATUS (prstatus structure) CORE 0x00000150 NT_PRSTATUS (prstatus structure) CORE 0x00000150 NT_PRSTATUS (prstatus structure) CORE 0x00000150 NT_PRSTATUS (prstatus structure) CORE 0x00000150 NT_PRSTATUS (prstatus structure) CORE 0x00000150 NT_PRSTATUS (prstatus structure) CORE 0x00000150 NT_PRSTATUS (prstatus structure) VMCOREINFO 0x00000785 Unknown note type: (0x00000000) Patch 1 adds API to vmcore module to allow drivers to register callback to collect the device specific hardware/firmware logs. The logs will be added to /proc/vmcore as elf notes. Patch 2 updates read and mmap logic to append device specific hardware/ firmware logs as elf notes. Patch 3 shows a cxgb4 driver example using the API to collect hardware/firmware logs in crash recovery kernel, before hardware is initialized.

Update read and mmap logic to append device dumps as additional notes before the other elf notes. We add device dumps before other elf notes because the other elf notes may not fill the elf notes buffer completely and we will end up with zero-filled data between the elf notes and the device dumps. Tools will then try to decode this zero-filled data as valid notes and we don't want that. Hence, adding device dumps before the other elf notes ensure that zero-filled data can be avoided. This also ensures that the device dumps and the other elf notes can be properly mmaped at page aligned address. Incorporate device dump size into the total vmcore size. Also update offsets for other program headers after the device dumps are added. Suggested-by: Eric Biederman <ebiederm@xmission.com>. Signed-off-by:

In commit bbc4e7d2 ("i40e: fix race condition with PTP_TX_IN_PROGRESS bits") we modified the code which handles Tx timestamps so that we would clear the progress bit as soon as possible. A later commit 0bc0706b ("i40e: check for Tx timestamp timeouts during watchdog") introduced similar code for detecting and handling cleanup of a blocked Tx timestamp. This code did not use the same pattern for cleaning up the skb. Update this code to wait to free the skb until after the bit lock is free, by first setting the ptp_tx_skb to NULL and clearing the lock. Signed-off-by:
