Drivers usually have a number of restrictions for running XDP - most common being buffer sizes, LRO and number of rings. Even though some drivers try to be helpful and print error messages experience shows that users don't often consult kernel logs on netlink errors. Try to use the new extended ack mechanism to carry the message back to user space. Signed-off-by:

As we propagate extended ack reporting throughout various paths in the kernel it may be that the same function is called with the extended ack parameter passed as NULL. One place where that happens is in drivers which have a centralized reconfiguration function called both from ndos and from ethtool_ops. Add a new helper for setting the error message in such conditions. Existing helper is left as is to encourage propagating the ext act fully wherever possible. It also makes it clear in the code which messages may be lost due to ext ack being NULL. Signed-off-by:

This patch allows users to enable/disable internal TX and/or RX clock delay for BCM5481x series PHYs so as to satisfy RGMII timing specifications. On a particular platform, whether TX and/or RX clock delay is required depends on how PHY connected to the MAC IP. This requirement can be specified through "phy-mode" property in the platform device tree. Signed-off-by:

The bnx2x driver is not providing proper alignment on the receive buffers it passes to build_skb(), causing skb_shared_info to be misaligned. skb_shared_info contains an atomic, and while PPC normally supports unaligned accesses, it does not support unaligned atomics. Aligning the size of rx buffers will ensure that page_frag_alloc() returns aligned addresses. This can be reproduced on PPC by setting the network MTU to 1450 (or other non-multiple-of-4) and then generating sufficient inbound network traffic (one or two large "wget"s usually does it), producing the following oops: Unable to handle kernel paging request for unaligned access at address 0xc00000ffc43af656 Faulting instruction address: 0xc00000000080ef8c Oops: Kernel access of bad area, sig: 7 [#1] SMP NR_CPUS=2048 NUMA PowerNV Modules linked in: vmx_crypto powernv_rng rng_core powernv_op_panel leds_powernv led_class nfsd ip_tables x_tables autofs4 xfs lpfc bnx2x mdio libcrc32c crc_t10dif crct10dif_generic crct10dif_common CPU: 104 PID: 0 Comm: swapper/104 Not tainted 4.11.0-rc8-00088-g4c761daf #2 task: c00000ffd4892400 task.stack: c00000ffd4920000 NIP: c00000000080ef8c LR: c00000000080eee8 CTR: c0000000001f8320 REGS: c00000ffffc33710 TRAP: 0600 Not tainted (4.11.0-rc8-00088-g4c761daf) MSR: 9000000000009033 <SF,HV,EE,ME,IR,DR,RI,LE> CR: 24082042 XER: 00000000 CFAR: c00000000080eea0 DAR: c00000ffc43af656 DSISR: 00000000 SOFTE: 1 GPR00: c000000000907f64 c00000ffffc33990 c000000000dd3b00 c00000ffcaf22100 GPR04: c00000ffcaf22e00 0000000000000000 0000000000000000 0000000000000000 GPR08: 0000000000b80008 c00000ffc43af636 c00000ffc43af656 0000000000000000 GPR12: c0000000001f6f00 c00000000fe1a000 000000000000049f 000000000000c51f GPR16: 00000000ffffef33 0000000000000000 0000000000008a43 0000000000000001 GPR20: c00000ffc58a90c0 0000000000000000 000000000000dd86 0000000000000000 GPR24: c000007fd0ed10c0 00000000ffffffff 0000000000000158 000000000000014a GPR28: c00000ffc43af010 c00000ffc9144000 c00000ffcaf22e00 c00000ffcaf22100 NIP [c00000000080ef8c] __skb_clone+0xdc/0x140 LR [c00000000080eee8] __skb_clone+0x38/0x140 Call Trace: [c00000ffffc33990] [c00000000080fb74] skb_clone+0x74/0x110 (unreliable) [c00000ffffc339c0] [c000000000907f64] packet_rcv+0x144/0x510 [c00000ffffc33a40] [c000000000827b64] __netif_receive_skb_core+0x5b4/0xd80 [c00000ffffc33b00] [c00000000082b2bc] netif_receive_skb_internal+0x2c/0xc0 [c00000ffffc33b40] [c00000000082c49c] napi_gro_receive+0x11c/0x260 [c00000ffffc33b80] [d000000066483d68] bnx2x_poll+0xcf8/0x17b0 [bnx2x] [c00000ffffc33d00] [c00000000082babc] net_rx_action+0x31c/0x480 [c00000ffffc33e10] [c0000000000d5a44] __do_softirq+0x164/0x3d0 [c00000ffffc33f00] [c0000000000d60a8] irq_exit+0x108/0x120 [c00000ffffc33f20] [c000000000015b98] __do_irq+0x98/0x200 [c00000ffffc33f90] [c000000000027f14] call_do_irq+0x14/0x24 [c00000ffd4923a90] [c000000000015d94] do_IRQ+0x94/0x110 [c00000ffd4923ae0] [c000000000008d90] hardware_interrupt_common+0x150/0x160 Signed-off-by:

Commit 7e26bf45 ("net: bridge: allow SW learn to take over HW fdb entries") added the ability to "take over an entry which was previously learned via HW when it shows up from a SW port". However, if an entry was learned via HW and then a control packet (e.g., ARP request) was trapped to the CPU, the bridge driver will update the entry and remove the externally learned flag, although the entry is still present in HW. Instead, only clear the externally learned flag in case of roaming. Fixes: 7e26bf45 ("net: bridge: allow SW learn to take over HW fdb entries") Signed-off-by:

The struct bpf_map_def was extended in commit fb30d4b7 ("bpf: Add tests for map-in-map") with member unsigned int inner_map_idx. This changed the size of the maps section in the generated ELF _kern.o files. Unfortunately the loader in bpf_load.c does not detect or handle this. Thus, older _kern.o files became incompatible, and caused hard-to-debug errors where the syscall validation rejected BPF_MAP_CREATE request. This patch only detect the situation and aborts load_bpf_file(). It also add code comments warning people that read this loader for inspiration for these pitfalls.

In the hip06 and hip07 SoCs, phy connect to mdio bus.The mdio module is probed with module_init, and, as such, is not guaranteed to probe before the HNS driver. So we need to support deferred probe. We check for probe deferral in the mac init, so we not init DSAF when there is no mdio, and free all resource, to later learn that we need to defer the probe. Signed-off-by:

Jakub Kicinski says: ==================== nfp: optimize XDP TX and small fixes This series optimizes the nfp XDP TX performance a little bit. I run quick tests on an Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz. Single core/queue performance for both touch and drop and touch and forward is above 20Mpps @64B packets, drop being 2Mpps faster.

For legacy reasons NFP FW may be compiled to DMA packets to a constant offset into the buffer and use the space before it for metadata. This ensures that packets data always start at a certain offset regardless of the amount of preceding metadata. If rx offset is set to 0 there may still be up to 64 bytes of metadata but metadata will start at the beginning of the buffer, instead of: data_start_offset = rx_offset - meta_len Even though we make the buffers larger to accommodate up to 64 bytes of metadata, if there is only N bytes of metadata, we will end up with N bytes of headroom and 64 - N bytes of tailroom. Therefore we can't rely on that space for XDP headroom. Make sure we always allocate full 256 bytes. This, unfortunately, means we can't fit the headroom on an u8 any more. Signed-off-by:

Reading TX queue indexes from the device memory on each interrupt is expensive. It's doubly expensive with XDP running since we have two TX rings to check there. If the software indexes indicate that the TX queue is completely empty, however, we don't need to look at the device completion index at all. The queuing CPU is doing a wmb() before kicking the device TX so we should be safe to assume on the CPU handling the completions will never see old value of the software copy of the index.

On the RX path we follow the "drop if allocation of replacement buffer fails" rule. With XDP we extended that to the TX action, so if XDP prog returned TX but allocation of replacement RX buffer failed, we will drop the packet. To improve our XDP TX performance extend the idea of rings being always full to XDP TX rings. Pre-fill the XDP TX rings with RX buffers, and when XDP prog returns TX action swap the RX buffer with the next buffer from the TX ring. XDP TX complete will no longer free the buffers but let them sit on the TX ring and wait for swap with RX buffer, instead. Signed-off-by:

Jiri Benc authored
The message "Cannot bind port X, err=Y" creates only confusion. In metadata based mode, failure of IPv6 socket creation is okay if IPv6 is disabled and no error message should be printed. But when IPv6 tunnel was requested, such failure is fatal. The vxlan_socket_create does not know when the error is harmless and when it's not. Instead of passing such information down to vxlan_socket_create, remove the message completely. It's not useful. We propagate the error code up to the user space and the port number comes from the user space. There's nothing in the message that the process creating vxlan interface does not know. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-04-30 This series contains updates to i40e and i40evf only. Jake provides majority of the changes in this series, starting with the renaming of a flag to avoid confusion. Then renamed a variable to a more meaningful name to clarify what is actually being done and to reduce confusion. Amortizes the wait time when initializing or disabling lots of VFs by using i40e_reset_all_vfs() and i40e_vsi_stop_rings_no_wait(). Cleaned up a unnecessary delay since pci_disable_sriov() already has its own delay, so need to add a additional delay when removing VFs. Avoid using the same name flags for both vsi->state and pf->state, to make code review easier and assist future work to use the correct state field when checking bits. Use DECLARE_BITMAP() to ensure that we always allocate enough space for flags. Replace hw_disabled_flags with the new _AUTO_DISABLED flags, which are more readable because we are not setting an *_ENABLED flag to disable the feature. Alex corrects a oversight where we were not reprogramming the ports after a reset, which was causing us to lose all of the receive tunnel offloads. Arnd Bergmann moves the declaration of a local variable to avoid a warning seen on architectures with larger pages about an unused variable. ==================== Signed-off-by:
