2018-10-10qed: Add support for virtual link.Sudarsana Reddy Kalluru2-52/+73
Currently driver registers to physical link notifications (of the device) from Management firmware (MFW). Driver doesn't get notified if there's a change in the virtual link e.g., link-flap on the peer PF interface. Virtual link indication from MFW reflects the per PF link status instead of the physical link. The patch adds driver support for, - Advertising the virtual link support to MFW. - Handling the virtual link notification from MFW. Please consider applying it to 'net-next'.

Alexei Starovoitov says: ==================== pull-request: bpf-next 2018-10-08 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow BPF programs to perform lookups for sockets in a network namespace. This would allow programs to determine early on in processing whether the stack is expecting to receive the packet, and perform some action (eg drop, forward somewhere) based on this information. 2) per-cpu cgroup local storage from Roman Gushchin. Per-cpu cgroup local storage is very similar to simple cgroup storage except all the data is per-cpu. The main goal of per-cpu variant is to implement super fast counters (e.g. packet counters), which don't require neither lookups, neither atomic operations in a fast path. The example of these hybrid counters is in selftests/bpf/netcnt_prog.c 3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet 4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski 5) rename of libbpf interfaces from Andrey Ignatov. libbpf is maturing as a library and should follow good practices in library design and implementation to play well with other libraries. This patch set brings consistent naming convention to global symbols. 6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov to let Apache2 projects use libbpf 7) various AF_XDP fixes from Björn and Magnus ==================== Signed-off-by: David S.

2018-10-08dpaa2-eth: Don't account Tx confirmation frames on NAPI pollIoana Ciocoi Radulescu2-26/+47
Until now, both Rx and Tx confirmation frames handled during NAPI poll were counted toward the NAPI budget. However, Tx confirmations are lighter to process than Rx frames, which can skew the amount of work actually done inside one NAPI cycle. Update the code to only count Rx frames toward the NAPI budget and set a separate threshold on how many Tx conf frames can be processed in one poll cycle. The NAPI poll routine stops when either the budget is consumed by Rx frames or when Tx confirmation frames reach this threshold.

2018-10-08net: phy: mscc: add support for VSC8574 PHYQuentin Schulz1-1/+319
The VSC8574 PHY is a 4-ports PHY that is 10/100/1000BASE-T, 100BASE-FX, 1000BASE-X and triple-speed copper SFP capable, can communicate with the MAC via SGMII, QSGMII or 1000BASE-X, supports WOL, downshifting and can set the blinking pattern of each of its 4 LEDs, supports SyncE as well as HP Auto-MDIX detection. This adds support for 10/100/1000BASE-T, SGMII/QSGMII link with the MAC, WOL, downshifting, HP Auto-MDIX detection and blinking pattern for its 4 LEDs. The VSC8574 has also an internal Intel 8051 microcontroller whose firmware needs to be patched when the PHY is reset. If the 8051's firmware has the expected CRC, its patching can be skipped. The microcontroller can be accessed from any port of the PHY, though the CRC function can only be done through the PHY that is the base PHY of the package (internal address 0) due to a limitation of the firmware. The GPIO register bank is a set of registers that are common to all PHYs in the package. So any modification in any register of this bank affects all PHYs of the package. If the PHYs haven't been reset before booting the Linux kernel and were configured to use interrupts for e.g. link status updates, it is required to clear the interrupts mask register of all PHYs before being able to use interrupts with any PHY. The first PHY of the package that will be init will take care of clearing all PHYs interrupts mask registers. Thus, we need to keep track of the init sequence in the package, if it's already been done or if it's to be done. Most of the init sequence of a PHY of the package is common to all PHYs in the package, thus we use the SMI broadcast feature which enables us to propagate a write in one register of one PHY to all PHYs in the same package.

2018-10-08net: phy: mscc: migrate to phy_select/restore_page functionsQuentin Schulz1-84/+62
The Microsemi PHYs have multiple banks of registers (called pages). Registers can only be accessed from one page, if we need a register from another page, we need to switch the page and the registers of all other pages are not accessible anymore. Basically, to read register 5 from page 0, 1, 2, etc., you do the same phy_read(phydev, 5); but you need to set the desired page beforehand. In order to guarantee that two concurrent functions do not change the page, we need to do some locking per page. This can be achieved with the use of phy_select_page and phy_restore_page functions but phy_write/read calls in-between those two functions shall be replaced by their lock-free alternative __phy_write/read.

Mark instructions that use pointers to areas in the stack outside of the current stack frame, and process them accordingly in mem_op_stack(). This way, we also support BPF-to-BPF calls where the caller passes a pointer to data in its own stack frame to the callee (typically, when the caller passes an address to one of its local variables located in the stack, as an argument). Thanks to Jakub and Jiong for figuring out how to deal with this case, I just had to turn their email discussion into this patch.

2018-10-08nfp: bpf: optimise save/restore for R6~R9 based on register usageQuentin Monnet3-23/+78
When pre-processing the instructions, it is trivial to detect what subprograms are using R6, R7, R8 or R9 as destination registers. If a subprogram uses none of those, then we do not need to jump to the subroutines dedicated to saving and restoring callee-saved registers in its prologue and epilogue. This patch introduces detection of callee-saved registers in subprograms and prevents the JIT from adding calls to those subroutines whenever we can: we save some instructions in the translated program, and some time at runtime on BPF-to-BPF calls and returns. If no subprogram needs to save those registers, we can avoid appending the subroutines at the end of the program.

2018-10-08nfp: bpf: fix return address from register-saving subroutine to calleeQuentin Monnet1-1/+27
On performing a BPF-to-BPF call, we first jump to a subroutine that pushes callee-saved registers (R6~R9) to the stack, and from there we goes to the start of the callee next. In order to do so, the caller must pass to the subroutine the address of the NFP instruction to jump to at the end of that subroutine. This cannot be reliably implemented when translated the caller, as we do not always know the start offset of the callee yet. This patch implement the required fixup step for passing the start offset in the callee via the register used by the subroutine to hold its return address.

2018-10-08nfp: bpf: account for additional stack usage when checking stack limitQuentin Monnet2-8/+68
Offloaded programs using BPF-to-BPF calls use the stack to store the return address when calling into a subprogram. Callees also need some space to save eBPF registers R6 to R9. And contrarily to kernel verifier, we align stack frames on 64 bytes (and not 32). Account for all this when checking the stack size limit before JIT-ing the program. This means we have to recompute maximum stack usage for the program, we cannot get the value from the kernel. In addition to adapting the checks on stack usage, move them to the finalize() callback, now that we have it and because such checks are part of the verification step rather than translation.

2018-10-08nfp: bpf: add main logics for BPF-to-BPF calls support in nfp driverQuentin Monnet5-4/+295
This is the main patch for the logics of BPF-to-BPF calls in the nfp driver. The functions called on BPF_JUMP | BPF_CALL and BPF_JUMP | BPF_EXIT were used to call helpers and exit from the program, respectively; make them usable for calling into, or returning from, a BPF subprogram as well. For all calls, push the return address as well as the callee-saved registers (R6 to R9) to the stack, and pop them upon returning from the calls. In order to limit the overhead in terms of instruction number, this is done through dedicated subroutines. Jumping to the callee actually consists in jumping to the subroutine, that "returns" to the callee: this will require some fixup for passing the address in a later patch. Similarly, returning consists in jumping to the subroutine, which pops registers and then return directly to the caller (but no fixup is needed here). Return to the caller is performed with the RTN instruction newly added to the JIT. For the few steps where we need to know what subprogram an instruction belongs to, the struct nfp_insn_meta is extended with a new subprog_idx field. Note that checks on the available stack size, to take into account the additional requirements associated to BPF-to-BPF calls (storing R6-R9 and return addresses), are added in a later patch.

The occurrences decrement is at iwl_fw_dbg_collect_trig, instead of iwl_fw_dbg_collect, which causes it to sometimes be skipped. Move it to the right location.

2018-10-06iwlwifi: mvm: show more HE radiotap data for TB PPDUsJohannes Berg1-36/+31
For trigger-based PPDUs, most values aren't part of the HE-SIG-A because they're preconfigured by the trigger frame. However, we still have this information since we used the trigger frame to configure the hardware, so we can (and do) read it back out and can thus show it in radiotap.

2018-10-06iwlwifi: mvm: decode HE information for MU (without ext info)Johannes Berg2-5/+6
When the info type is MU, we still have the data from the TSF overload words, so should decode that. When it's MU_EXT_INFO we additionally have the SIG-B common 0/1/2 fields. Also document the validity depending on the info type and fix the name of the regular TB PPDU info type accordingly.

If we use the iwl_pcie_txq_build_tfd() return value for BIT(), we should validate that it's not going to be negative, so do the check and bail out if we hit an error. We shouldn't, as we check if it'll fit beforehand, but better be safe. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2018-10-06iwlwifi: nvm: get num of hw addresses from firmwareNaftali Goldstein2-8/+16
With NICs that don't read the NVM directly and instead rely on getting the relevant data from the firmware, the number of reserved MAC addresses was not added to the API. This caused the driver to assume there is only one address which results in all interfaces getting the same address. Update the API to fix this. While at it, fix-up the comments with firmware api names to actually match what we have in the firmware.
