| 2020-09-25 | intel-ethernet: clean up W=1 warnings in kdoc |   Jesse Brandeburg | 1 | -1/+2 | |
| This takes care of all of the trivial W=1 fixes in the Intel Ethernet drivers, which allows developers and maintainers to build more of the networking tree with more complete warning checks. There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers. Inspired by Lee Jones' series of wireless work to do the same.

There are two small conflicts when pulling, resolve as follows: 1) Merge conflict in tools/lib/bpf/libbpf.c between 88a82120282b ("libbpf: Factor out common ELF operations and improve logging") in bpf-next and 1e891e513e16 ("libbpf: Fix map index used in error message") in net-next. Resolve by taking the hunk in bpf-next: [...] scn = elf_sec_by_idx(obj, obj->efile.btf_maps_shndx); data = elf_sec_data(obj, scn); if (!scn || !data) { pr_warn("elf: failed to get %s map definitions for %s\n", MAPS_ELF_SEC, obj->path); return -EINVAL; } [...] 2) Merge conflict in drivers/net/ethernet/mellanox/mlx5/core/en/xsk/rx.c between 9647c57b11e5 ("xsk: i40e: ice: ixgbe: mlx5: Test for dma_need_sync earlier for better performance") in bpf-next and e20f0dbf204f ("net/mlx5e: RX, Add a prefetch command for small L1_CACHE_BYTES") in net-next.

| 2020-08-31 | xsk: i40e: ice: ixgbe: mlx5: Rename xsk zero-copy driver interfaces |   Magnus Karlsson | 1 | -3/+3 | |
| Rename the AF_XDP zero-copy driver interface functions to better reflect what they do after the replacement of umems with buffer pools in the previous commit. Mostly it is about replacing the umem name from the function names with xsk_buff and also have them take the a buffer pool pointer instead of a umem. The various ring functions have also been renamed in the process so that they have the same naming convention as the internal functions in xsk_queue.h. This so that it will be clearer what they do and also for consistency.

| 2020-08-31 | xsk: i40e: ice: ixgbe: mlx5: Pass buffer pool to driver instead of umem | Magnus Karlsson | 1 | -17/+17 | |
| Replace the explicit umem reference passed to the driver in AF_XDP zero-copy mode with the buffer pool instead. This in preparation for extending the functionality of the zero-copy mode so that umems can be shared between queues on the same netdev and also between netdevs. In this commit, only an umem reference has been added to the buffer pool struct. But later commits will add other entities to it. These are going to be entities that are different between different queue ids and netdevs even though the umem is shared between them.

| 2020-07-30 | ixgbe: use generic power management |   Vaibhav Gupta | 1 | -46/+15 | |
| With legacy PM hooks, it was the responsibility of a driver to manage PCI states and also the device's power state. The generic approach is to let PCI core handle the work. ixgbe_suspend() calls __ixgbe_shutdown() to perform intermediate tasks. __ixgbe_shutdown() modifies the value of "wake" (device should be wakeup enabled or not), responsible for controlling the flow of legacy PM. Since, PCI core has no idea about the value of "wake", new code for generic PM may produce unexpected results. Thus, use "device_set_wakeup_enable()" to wakeup-enable the device accordingly.

Shiraz moves the client header so that it can easily be shared between the i40e LAN driver and i40iw RDMA driver. Jesse cleans up the unused defines, since they are just dead weight. Alek reduces the unreasonably long wait time for a PF reset after reboot by using jiffies to limit the maximum wait time for the PF reset to succeed. Added additional logging to let the user know when the driver transitions into recovery mode. Adds new device support for our 5 Gbps NICs. Todd adds a check to see if MFS is set after warm reboot and notifies the user when MFS is set to anything lower than the default value. Arkadiusz fixes a possible race condition, where were holding a spin-lock while in atomic context. v2: removed code comments that were no longer applicable in patch 2 of the series.

| 2020-06-25 | net/intel: remove driver versions from Intel drivers | Jeff Kirsher | 1 | -6/+4 | |
| As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

| 2020-05-14 | ixgbe: Add XDP frame size to driver |   Jesper Dangaard Brouer | 1 | -8/+26 | |
| This driver uses different memory models depending on PAGE_SIZE at compile time. For PAGE_SIZE 4K it uses page splitting, meaning for normal MTU frame size is 2048 bytes (and headroom 192 bytes). For larger MTUs the driver still use page splitting, by allocating order-1 pages (8192 bytes) for RX frames. For PAGE_SIZE larger than 4K, driver instead advance its rx_buffer->page_offset with the frame size "truesize". For XDP frame size calculations, this mean that in PAGE_SIZE larger than 4K mode the frame_sz change on a per packet basis. For the page split 4K PAGE_SIZE mode, xdp.frame_sz is more constant and can be updated once outside the main NAPI loop. The default setting in the driver uses build_skb(), which provides the necessary headroom and tailroom for XDP-redirect in RX-frame (in both modes). There is one complication, which is legacy-rx mode (configurable via ethtool priv-flags). There are zero headroom in this mode, which is a requirement for XDP-redirect to work. The conversion to xdp_frame (convert_to_xdp_frame) will detect this insufficient space, and xdp_do_redirect() call will fail. This is deemed acceptable, as it allows other XDP actions to still work in legacy-mode. In legacy-mode + larger PAGE_SIZE due to lacking tailroom, we also accept that xdp_adjust_tail shrink doesn't work.

| The ixgbe driver have another memory model when compiled on archs with PAGE_SIZE above 4096 bytes. In this mode it doesn't split the page in two halves, but instead increment rx_buffer->page_offset by truesize of packet (which include headroom and tailroom for skb_shared_info). This is done correctly in ixgbe_build_skb(), but in ixgbe_rx_buffer_flip which is currently only called on XDP_TX and XDP_REDIRECT, it forgets to add the tailroom for skb_shared_info. This breaks XDP_REDIRECT, for veth and cpumap. Fix by adding size of skb_shared_info tailroom. Maintainers notice: This fix have been queued to Jeff.

| Changing a network device MTU can be a fairly frequent operation, and failure to change the MTU is reflected to user-space properly, both by an appropriate message as well as by looking at whether the device's MTU matches the configuration. Demote the prints to debug prints by using netdev_dbg(), making all Intel wired LAN drivers consistent, since they used a mixture of PCI device and network device prints before.

| 2019-11-04 | ixgbe: protect TX timestamping from API misuse |   Manjunath Patil | 1 | -1/+2 | |
| HW timestamping can only be requested for a packet if the NIC is first setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the ixgbe driver still allowed TX packets to request HW timestamping. In this situation, we see 'clearing Tx Timestamp hang' noise in the log. Fix this by checking that the NIC is configured for HW TX timestamping before accepting a HW TX timestamping request. Similar-to: commit 26bd4e2db06b ("igb: protect TX timestamping from API misuse") commit 0a6f2f05a2f5 ("igb: Fix a test with HWTSTAMP_TX_ON") Signed-off-by: Manjunath Patil <manjunath.b.patil@oracle.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> | |||||

| The ixgbe driver currently does IPsec TX offloading based on an existing secpath. However, the secpath can also come from the RX side, in this case it is misinterpreted for TX offload and the packets are dropped with a "bad sa_idx" error. Fix this by using the xfrm_offload() function to test for TX offload.

| 2019-09-09 | ixgbe: sync the first fragment unconditionally |   Firo Yang | 1 | -7/+9 | |
| In Xen environment, if Xen-swiotlb is enabled, ixgbe driver could possibly allocate a page, DMA memory buffer, for the first fragment which is not suitable for Xen-swiotlb to do DMA operations. Xen-swiotlb have to internally allocate another page for doing DMA operations. This mechanism requires syncing the data from the internal page to the page which ixgbe sends to upper network stack. However, since commit f3213d932173 ("ixgbe: Update driver to make use of DMA attributes in Rx path"), the unmap operation is performed with DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed. Since the sync isn't performed, the upper network stack could receive a incomplete network packet. By incomplete, it means the linear data on the first fragment(between skb->head and skb->end) is invalid. So we have to copy the data from the internal xen-swiotlb page to the page which ixgbe sends to upper network stack through the sync operation. More details from Alexander Duyck: Specifically since we are mapping the frame with DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result a sync is not performed on an unmap and must be done manually as we skipped it for the first frag. As such we need to always sync before possibly performing a page unmap operation.

| Daniel Borkmann says: ==================== The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add the ability to use unaligned chunks in the AF_XDP umem. By relaxing where the chunks can be placed, it allows to use an arbitrary buffer size and place whenever there is a free address in the umem. Helps more seamless DPDK AF_XDP driver integration. Support for i40e, ixgbe and mlx5e, from Kevin and Maxim. 2) Addition of a wakeup flag for AF_XDP tx and fill rings so the application can wake up the kernel for rx/tx processing which avoids busy-spinning of the latter, useful when app and driver is located on the same core. Support for i40e, ixgbe and mlx5e, from Magnus and Maxim. 3) bpftool fixes for printf()-like functions so compiler can actually enforce checks, bpftool build system improvements for custom output directories, and addition of 'bpftool map freeze' command, from Quentin. 4) Support attaching/detaching XDP programs from 'bpftool net' command, from Daniel. 5) Automatic xskmap cleanup when AF_XDP socket is released, and several barrier/{read,write}_once fixes in AF_XDP code, from Björn. 6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf inclusion as well as libbpf versioning improvements, from Andrii. 7) Several new BPF kselftests for verifier precision tracking, from Alexei. 8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya. 9) And more BPF kselftest improvements all over the place, from Stanislav. 10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub. 11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan. 12) Add BPF-to-BPF call and BTF line info support for s390x JIT, from Yauheni. 13) Small optimization in arm64 JIT to spare 1 insns for BPF_MOD, from Jerin. 14) Fix an error check in bpf_tcp_gen_syncookie() helper, from Petar. 15) Various minor fixes and cleanups, from Nathan, Masahiro, Masanari, Peter, Wei, Yue. ==================== Signed-off-by: David S.

| This commit replaces ndo_xsk_async_xmit with ndo_xsk_wakeup. This new ndo provides the same functionality as before but with the addition of a new flags field that is used to specifiy if Rx, Tx or both should be woken up. The previous ndo only woke up Tx, as implied by the name. The i40e and ixgbe drivers (which are all the supported ones) are updated with this new interface. This new ndo will be used by the new need_wakeup functionality of XDP sockets that need to be able to wake up both Rx and Tx driver processing.

| 2019-04-08 | drivers: Remove explicit invocations of mmiowb() |   Will Deacon | 1 | -5/+0 | |
| mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

| 2019-04-01 | net: move skb->xmit_more hint to softnet data |   Florian Westphal | 1 | -1/+1 | |
| There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.
