Introduce two new attributes to be used for qdisc creation and dumping. One for ingress block, one for egress block. Introduce a set of ops that qdisc which supports block sharing would implement. Passing block indexes in qdisc change is not supported yet and it is checked and forbidded. In future, these attributes are to be reused for specifying block indexes for classes as well. As of this moment however, it is not supported so a check is in place to forbid it. Suggested-by:

As the tcm_ifindex with value TCM_IFINDEX_MAGIC_BLOCK is invalid ifindex, use it to indicate that we work with block, instead of qdisc. So if tcm_ifindex is set to TCM_IFINDEX_MAGIC_BLOCK, tcm_parent is used to carry block_index. If the block is set to be shared between at least 2 qdiscs, it is forbidden to use the qdisc handle to add/delete filters. In that case, userspace has to pass block_index. Also, for dump of the filters, in case the block is shared in between at least 2 qdiscs, the each filter is dumped with tcm_ifindex value TCM_IFINDEX_MAGIC_BLOCK and tcm_parent set to block_index. That gives the user clear indication, that the filter belongs to a shared block and not only to one qdisc under which it is dumped. Suggested-by:

During block bind, we need to check tc offload feature. If it is disabled yet still the block contains offloaded filters, forbid the bind. Also forbid to register callback for a block that already contains offloaded filters, as the play back is not supported now. For keeping track of offloaded filters there is a new counter introduced, alongside with couple of helpers called from cls_* code. These helpers set and clear TCA_CLS_FLAGS_IN_HW flag. Signed-off-by:

Couple of classifiers call netif_keep_dst directly on q->dev. That is not possible to do directly for shared blocke where multiple qdiscs are owning the block.

Allow qdiscs to share filter blocks among them. Each qdisc type has to use block get/put extended modifications that enable sharing. Shared blocks are tracked within each net namespace and identified by u32 index. This index is passed from user during the qdisc creation. If user passes index that is not used by any other qdisc, new block is created. If user passes index that is already used, the existing block will be re-used. Signed-off-by:

So far, there was possible only to register a single filter chain pointer to block->chain[0]. However, when the blocks will get shareable, we need to allow multiple filter chain pointers registration. Signed-off-by:

Michael Chan says: ==================== bnxt_en: Updates for net-next. First, we upgrade the firmware interface spec. Due to a change in the toolchains, the auto-generated bnxt_hsi.h does not match the old bnxt_hsi.h and the patch is really big. This should be just one-time. Going forward, changes should be incremental. The next 10 patches implement a new scheme for the PF and VF drivers to allocate and reserve resources. The new scheme is more flexible and allows dynamic and asymmetric distribution of resources, whereas the old scheme is static and even distribution. The last few patches add cacheline size setting, a couple of PCI IDs, better management of VF MAC address, and a better parent switchdev ID for dual-port devices. ==================== Signed-off-by: -

Currently the driver exports different switchdev PARENT_IDs for representors belonging to different SR-IOV PF-pools of an adapter. This is not correct as the adapter can switch across all vports of an adapter. This patch fixes this by exporting a common switchdev PARENT_ID for all reps of an adapter. The PCIE DSN is used as the id. Signed-off-by:

Instead of the old method of evenly dividing the resources to the VFs, use the new firmware API to specify min and max resources for each VF. This way, there is more flexibility for each VF to allocate more or less resources. The min is the absolute minimum for each VF to function. The max is the global resources minus the resources used by the PF. Each VF is guaranteed the min. Up to max resources may be available for some VFs. The PF driver can use one of 2 strategies specified in NVRAM to assign the resources. The old legacy strategy of evenly dividing the resources or the new flexible strategy. Signed-off-by:

In bnxt_rfs_capable(), add call to reserve vnic resources to support NTUPLE. Return true if we can successfully reserve enough vnics. Otherwise, reserve the minimum 1 VNIC for normal operations not supporting NTUPLE and return false. Also, suppress warning message about not enough resources for NTUPLE when only 1 RX ring is in use. NTUPLE filters by definition require multiple RX rings. Signed-off-by:

The new method will call firmware to reserve the desired tx, rx, cmpl rings, ring groups, stats context, and vnic resources. A second query call will check the actual resources that firmware is able to reserve. The driver will then trim and adjust based on the actual resources provided by firmware. The driver will then reserve the final resources in use. This method is a more flexible way of using hardware resources. The resources are not fixed and can by adjusted by firmware. The driver adapts to the available resources that the firmware can reserve for the driver. Signed-off-by:

In combined mode, the driver is currently not setting RX and TX ring numbers the same when firmware can allocate more RX than TX or vice versa. This will confuse the user as the ethtool convention assumes they are the same in combined mode. Fix it by adding bnxt_trim_dflt_sh_rings() to trim RX and TX ring numbers to be the same as the completion ring number in combined mode. Note that if TCs are enabled and/or XDP is enabled, the number of TX rings will not be the same as RX rings in combined mode. Signed-off-by:

After SRIOV has been enabled and disabled, the MSIX vectors assigned to the VFs have to be re-initialized. Otherwise they cannot be re-used by the PF. For example, increasing the number of PF rings after disabling SRIOV may fail if the PF uses MSIX vectors previously assigned to the VFs. To fix this, we add logic in bnxt_restore_pf_fw_resources() to close the NIC, clear and re-init MSIX, and re-open the NIC. Signed-off-by:

Martin Blumenstingl says: ==================== dwmac-meson8b: clock fixes for Meson8b this series is now successfully tested, thus we think it's ready to be applied to your net-next tree. Emiliano reported [0] that he couldn't get dwmac-meson8b to work on his Odroid-C1. This is the (hopefully) final version of this series, which was successfully tested. Due to the fact that the public S805/S905/S912 datasheets all seem to be outdated regarding the description of the PRG_ETH0 (also called PRG_ETHERNET_ADDR0) register Linus Lüssing offered to help testing with an oscilloscope and an Odroid-C1. I would like to say HUGE thanks to him at this point as he spent hours figuring out the effects of the bits that are (though to be) relevant to get Ethernet working on the Odroid-C1. We tested three scenarios, all based on version 3 of this series: 1) MPLL2 at ~500MHz, m250_div set to 1, bit 10 enabled this resulted in a clock rate twice as high as expected at the RGMII TX clock pin (250MHz instead of 125MHz for Gbit connections and 50MHz instead of 25MHz for 100Mbit/s connections). it did not change the rate at the XTAL_IN pin of PHY (which stayed consistenly at 25MHz) 2) MPLL2 at ~250MHz, m250_div set to 1, bit 10 disabled the oscilloscope shows "no clock" for the RGMII TX clock pin at it's highest resolution (and random rates at lower resolutions). XTAL_IN is still at 25MHz 3) MPLL2 at ~250MHz, m250_div set to 1, bit 10 enabled this resulted in a 125MHz signal at the RGMII TX clock pin for Gbit speeds and 25MHz for 100Mbit/s - both values are as expected. The rate on the XTAL_IN pin was at 25MHz -> boot-logs (with the PRG_ETH0 register value) and screenshots from the readings of the oscilloscope can be found at: https://metameute.de/~tux/linux/amlogic/odroidc1/ethernet/ Version 4 of this series is based on the results from Linus Lüssing's help with the oscilloscope and Odroid-C1. Unfortunately I don't have any Meson8b boards with RGMII PHY so I could only partially test this. @Emiliano: Could you please give this version a try and let me know about the results (preferably with a "Tested-by" if it works)? You obviously still need your two "ARM: dts: meson8b" patches which - add the amlogic,meson8b-dwmac" compatible to meson8b.dtsi - enable Ethernet on the Odroid-C1 (according to your last thest a TX delay of 4ns is required to make it work properly) When testing on Meson8b this also needs a fix for the MPLL clock driver: "clk: meson: mpll: use 64-bit maths in params_from_rate", see: https://patchwork.kernel.org/patch/10131677/ I have tested this myself on a Khadas VIM (GXL SoC, internal RMII PHY) and a Khadas VIM2 (GXM SoC, external RGMII PHY). Both are still working fine (so let's hope that this also fixes your Meson8b issue :)). changes since v4 at [4]: - dropped "RFT" status since Jerome tested this series successfully! - dropped PATCH #2 ("simplify generating the clock names"). I will improve the whole clock registration in a separate series. since that patch didn't really improve anything I dropped it for now - added Jerome's Acked-/Reviewed-/Tested-by's - many thanks! changes since v3 at [3]: - renamed the function PATCH #1 from meson8b_init_rgmii_clk to meson8b_init_rgmii_tx_clk since we now know what the register bits mean - rewrote PATCH #3 because bit 10 is a gate clock and it seems that there is an internal fixed divide-by-2 clock. see the patch description for a detailed explanation - updated the description of PATCH #4 and #5 as the clock we're trying to fix is the "RGMII TX" clock (old version stated that this is the "RGMII clock" or "PHY reference clock"). also updated the numbers in the description now that we have the clock hierarchy right (at least we hope so) changes since v2 at [2]: - added PATCH #2 to make the following patch easier - Emiliano reported that there's currently another bug in the dwmac-meson8b driver which prevents it from working with RGMII PHYs on Meson8b: bit 10 of the PRG_ETH0 register is configures a clock gate (instead of a divide by 5 or divide by 10 clock divider). This has not been visible on GXBB and later due to the input clock which always led to a selection of "divide by 10" (which is done internally in the IP block, but the bit actually means "enable RGMII clock output"). PATCH #3 was added to address this issue. - the commit message of PATCH #4 and #5 (formerly PATCH #2 and #3) were updated and the patch itself rebased because the m25_div clock was removed with the new PATCH #3 (so some of the statements were not valid anymore) changes since v1 at [1]: - changed the subject of the cover-letter to indicate that this is all about the RGMII clock - added PATCH #1 which ensures that we don't unnecessarily change the parent clocks in RMII mode (and also makes the code easier to understand) - changed subject of PATCH #2 (formerly PATCH #1) to state that this is about the RGMII clock - added Jerome's Reviewed-by to PATCH #2 (formerly PATCH #1) - replaced PATCH #3 (formerly PATCH #2) with one that sets CLK_SET_RATE_PARENT on the mux and thus re-configures the MPLL2 clock on Meson8b correctly [0] http://lists.infradead.org/pipermail/linux-amlogic/2017-December/005596.html [1] http://lists.infradead.org/pipermail/linux-amlogic/2017-December/005848.html [2] http://lists.infradead.org/pipermail/linux-amlogic/2017-December/005861.html [3] http://lists.infradead.org/pipermail/linux-amlogic/2017-December/005899.html [4] http://lists.infradead.org/pipermail/linux-amlogic/2018-January/006125.html ==================== Tested-by:

On Meson8b the only valid input clock is MPLL2. The bootloader configures that to run at 500002394Hz which cannot be divided evenly down to 125MHz using the m250_div clock. Currently the common clock framework chooses a m250_div of 2 - with the internal fixed "divide by 10" this results in a RGMII TX clock of 125001197Hz (120Hz above the requested 125MHz). Letting the common clock framework propagate the rate changes up to the parent of m250_mux allows us to get the best possible clock rate. With this patch the common clock framework calculates a rate of very-close-to-250MHz (249999701Hz to be exact) for the MPLL2 clock (which is the mux input). Dividing that by 2 (which is an internal, fixed divider for the RGMII TX clock) gives us an RGMII TX clock of 124999850Hz (which is only 150Hz off the requested 125MHz, compared to 1197Hz based on the MPLL2 rate set by u-boot and the Amlogic GPL kernel sources). SoCs from the Meson GX series are not affected by this change because the input clock is FCLK_DIV2 whose rate cannot be changed (which is fine since it's running at 1GHz, so it's already a multiple of 250MHz and 125MHz).

Meson8b only supports MPLL2 as clock input. The rate of the MPLL2 clock set by Odroid-C1's u-boot is close to (but not exactly) 500MHz. The exact rate is 500002394Hz, which is calculated in drivers/clk/meson/clk-mpll.c using the following formula: DIV_ROUND_UP_ULL((u64)parent_rate * SDM_DEN, (SDM_DEN * n2) + sdm) Odroid-C1's u-boot configures MPLL2 with the following values: - SDM_DEN = 16384 - SDM = 1638 - N2 = 5 The 250MHz clock (m250_div) inside dwmac-meson8b driver is derived from the MPLL2 clock. Due to MPLL2 running slightly faster than 500MHz the common clock framework chooses a divider which is too big to generate the 250MHz clock (a divider of 2 would be needed, but this is rounded up to a divider of 3). This breaks the RTL8211F RGMII PHY on Odroid-C1 because it requires a (close to) 125MHz RGMII TX clock (on Gbit speeds, the IP block internally divides that down to 25MHz on 100Mbit/s connections and 2.5MHz on 10Mbit/s connections - we don't need any special configuration for that). Round the divider to the closest value to prevent this issue on Meson8b. This means we'll now end up with a clock rate for the RGMII TX clock of 125001197Hz (= 125MHz plus 1197Hz), which is close-enough to 125MHz. This has no effect on the Meson GX SoCs since there fclk_div2 is used as input clock, which has a rate of 1000MHz (and thus is divisible cleanly to 250MHz and 125MHz).

Tests (using an oscilloscope and an Odroid-C1 board with a RTL8211F RGMII PHY) have shown that the PRG_ETH0 register behaves as follows: - bit 4 is a mux to choose between two parent clocks. according to the public S805 datasheet the only supported parent clock is MPLL2 (this was not verified using the oscilloscope). The public S805/S905 datasheet claims that this bit is reserved. - bits 9:7 control a one-based divider (register value 1 means "divide by 1", etc.) for the input clock. we call this clock the "m250_div" clock because it's value is always supposed to be (close to) 250MHz (see below for an explanation). The description in the public S805/S905 datasheet is a bit cryptic, but it comes down to "input clock = 250MHz * value" (which could also be expressed as "250MHz = input clock / value") - there seems to be an internal fixed divide-by-2 clock which takes the output from the m250_div and divides it by 2. This is not unusual on Amlogic SoCs, since the SDIO (MMC) driver also uses an internal fixed divide-by-2 clock. This is not documented in the public S805/S905 datasheet - bit 10 controls a gate clock which enables or disables the RGMII TX clock (which is an output on the MAC/SoC and an input in the PHY). we call this the "rgmii_tx_en" clock. if this bit is set to "0" the RGMII TX clock output is close to 0 The description for this bit in the public S805/S905 datasheet is "Generate 25MHz clock for PHY". Based on these tests it's believed that this is wrong, and should probably read "Generate the 125MHz RGMII TX clock for the PHY" - the RGMII TX clock has to be set to 125MHz - the IP block adjusts the output (automatically) depending on the line speed (RGMII specifies that Gbit connections use a 125MHz clock, 100Mbit/s connections use a 25MHz clock and 10Mbit/s connections use a 2.5MHz clock. only Gbit and 100Mbit/s were tested with an oscilloscope). Due to the requirement that this clock always has to be set to 125MHz and due to the fixed divide-by-2 parent clock this means that m250_div will always end up with a rate of (close to) 250MHz. - bits 6:5 are the TX delay, which is also named "clock phase" in some of Amlogic's older GPL kernel sources. The PHY also has an XTAL_IN pin where a 25MHz clock has to be provided. Tests with the oscilloscope have shown that this is routed to a crystal right next to the RTL8211F PHY. The same seems to be true on the Khadas VIM2 (which uses a GXM SoC) board - however the 25MHz crystal is on the other side of the PCB there. This updates the clocks in the dwmac-meson8b driver by replacing the "m25_div" with the "rgmii_tx_en" clock and additionally introducing a fixed divide-by-2 clock between "m250_div" and "rgmii_tx_en". Now we also need to set a frequency of 125MHz on the RGMII clock (opposed to the 25MHz we set before, with that non-existing divide-by-5-or-10 divider). Special thanks go to Linus Lüssing for testing the various bits and checking the results with an oscilloscope on his Odroid-C1!

Neither the m25_div_clk nor the m250_div_clk or m250_mux_clk are used in RMII mode. The m25_div_clk output is routed to the RGMII PHY's "RGMII clock". This means that we don't need to configure the clocks in RMII mode. The driver however did this - with no effect since the clocks are not routed to the PHY in RMII mode. While here also rename meson8b_init_clk to meson8b_init_rgmii_tx_clk to make it easier to understand the code.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-01-17 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add initial BPF map offloading for nfp driver. Currently only programs were supported so far w/o being able to access maps. Offloaded programs are right now only allowed to perform map lookups, and control path is responsible for populating the maps. BPF core infrastructure along with nfp implementation is provided, from Jakub. 2) Various follow-ups to Josef's BPF error injections. More specifically that includes: properly check whether the error injectable event is on function entry or not, remove the percpu bpf_kprobe_override and rather compare instruction pointer with original one, separate error-injection from kprobes since it's not limited to it, add injectable error types in order to specify what is the expected type of failure, and last but not least also support the kernel's fault injection framework, all from Masami. 3) Various misc improvements and cleanups to the libbpf Makefile. That is, fix permissions when installing BPF header files, remove unused variables and functions, and also install the libbpf.h header, from Jesper. 4) When offloading to nfp JIT and the BPF insn is unsupported in the JIT, then reject right at verification time. Also fix libbpf with regards to ELF section name matching by properly treating the program type as prefix. Both from Quentin. 5) Add -DPACKAGE to bpftool when including bfd.h for the disassembler. This is needed, for example, when building libfd from source as bpftool doesn't supply a config.h for bfd.h. Fix from Jiong. 6) xdp_convert_ctx_access() is simplified since it doesn't need to set target size during verification, from Jesper. 7) Let bpftool properly recognize BPF_PROG_TYPE_CGROUP_DEVICE program types, from Roman. 8) Various functions in BPF cpumap were not declared static, from Wei. 9) Fix a double semicolon in BPF samples, from Luis. ==================== Signed-off-by: -

Pull rdma fixes from Doug Ledford: "We had a few more items creep up over the last week. Given we are in -rc8, these are obviously limited to bugs that have a big downside and for which we are certain of the fix. The first is a straight up oops bug that all you have to do is read the code to see it's a guaranteed 100% oops bug. The second is a use-after-free issue. We get away lucky if the queue we are shutting down is empty, but if it isn't, we can end up oopsing. We really need to drain the queue before destroying it. The final one is an issue with bad user input causing us to access our port array out of bounds. While fixing the array out of bounds issue, it was noticed that the original code did the same thing twice (the call to rdma_ah_set_port_num()), so its removal is not balanced by a readd elsewhere, it was already where it needed to be in addition to where it didn't need to be.

Jakub Kicinski says: ==================== This series combines a number of random improvements ranging from libbpf to nfp driver. NFP patches make better use of the verifier log. There is a requested adjustment to the map offload code, and a warning fix for a W=1 build to the disassembler. Quentin also fixes the libbpf program type detection, while Jiong allows the use of libbfd compiled from source. ==================== Signed-off-by: -
