2018-11-07intel-ethernet: software timestamp skbs as late as possibleJacob Keller5-10/+10
Many of the Intel Ethernet drivers call skb_tx_timestamp() earlier than necessary. Move the calls to this function to the latest point possible, just prior to notifying hardware of the new Tx packet when we bump the tail register. This affects i40e, iavf, igb, igc, and ixgbe. The e100, e1000, e1000e, fm10k, and ice drivers already call the skb_tx_timestamp() function just prior to indicating the Tx packet to hardware, so they do not need to be changed.

2018-11-07ixgbevf: add support for software timestampsJacob Keller1-0/+2
Add a call to skb_tx_timestamp in the ixgbevf_tx_map function. This enables software timestamping for packets sent over this device driver. The call is placed just prior to when we notify hardware of the new packet, in order to software timestamp as close as possible to when the hardware will transmit.

2018-11-07ixgbe: allow IPsec Tx offload in VEPA modeShannon Nelson1-1/+3
When it's possible that the PF might end up trying to send a packet to one of its own VFs, we have to forbid IPsec offload because the device drops the packets into a black hole. See commit 47b6f50077e6 ("ixgbe: disallow IPsec Tx offload when in SR-IOV mode") for more info. This really is only necessary when the device is in the default VEB mode. If instead the device is running in VEPA mode, the packets will go through the encryption engine and out the MAC/PHY as normal, and get "hairpinned" as needed by the switch. So let's not block IPsec offload when in VEPA mode.

2018-11-07ixgbe: don't clear_bit on xdp_ring->state if xdp_ring is nullColin Ian King1-1/+2
There is an earlier check to see if xdp_ring is null when configuring the tx ring, so assuming that it can still be null, the clearing of the xdp_ring->state currently could end up with a null pointer dereference. Fix this by only clearing the bit if xdp_ring is not null.

This change resolves a driver bug where the driver is logging a message that says "Spoofed packets detected".

2018-10-31ixgbe/ixgbevf: fix XFRM_ALGO dependencyJeff Kirsher7-12/+30
Based on the original work from Arnd Bergmann. When XFRM_ALGO is not enabled, the new ixgbe IPsec code produces a link error: drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa': ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname' Simply selecting XFRM_ALGO from here causes circular dependencies, so to fix it, we probably want this slightly more complex solution that is similar to what other drivers with XFRM offload do: A separate Kconfig symbol now controls whether we include the IPsec offload code. To keep the old behavior, this is left as 'default y'. The dependency in XFRM_OFFLOAD still causes a circular dependency but is not actually needed because this symbol is not user visible, so removing that dependency on top makes it all work.

2018-10-31fm10k: ensure completer aborts are marked as non-fatal after a resumeJacob Keller1-20/+28
VF drivers can trigger PCIe completer aborts any time they read a queue that they don't own. Even in nominal circumstances, it is not possible to prevent the VF driver from reading queues it doesn't own. VF drivers may attempt to read queues it previously owned, but which it no longer does due to a PF reset. Normally these completer aborts aren't an issue. However, on some platforms these trigger machine check errors. This is true even if we lower their severity from fatal to non-fatal. Indeed, we already have code for lowering the severity. We could attempt to mask these errors conditionally around resets, which is the most common time they would occur. However this would essentially be a race between the PF and VF drivers, and we may still occasionally see machine check exceptions on these strictly configured platforms. Instead, mask the errors entirely any time we resume VFs. By doing so, we prevent the completer aborts from being sent to the parent PCIe device, and thus these strict platforms will not upgrade them into machine check errors. Additionally, we don't lose any information by masking these errors, because we'll still report VFs which attempt to access queues via the FUM_BAD_VF_QACCESS errors. Without this change, on platforms where completer aborts cause machine check exceptions, the VF reading queues it doesn't own could crash the host system. Masking the completer abort prevents this, so we should mask it for good, and not just around a PCIe reset. Otherwise malicious or misconfigured VFs could cause the host system to crash. Because we are masking the error entirely, there is little reason to also keep setting the severity bit, so that code is also removed.

2018-10-31fm10k: fix SM mailbox full conditionNgai-Mint Kwan1-1/+2
Current condition will always incorrectly report a full SM mailbox if an IES API application is not running. Due to this, the "fm10k_service_task" will be infinitely queued into the driver's workqueue. This, in turn, will cause a "kworker" thread to report 100% CPU utilization and might cause "soft lockup" events or system crashes. To fix this issue, a new condition is added to determine if the SM mailbox is in the correct state of FM10K_STATE_OPEN before proceeding. In other words, an instance of the IES API must be running. If there is, the remainder of the flow stays the same which is to determine if the SM mailbox capacity has been exceeded or not and take appropriate action.

2018-10-31igb: shorten maximum PHC timecounter update intervalMiroslav Lichvar1-1/+7
The timecounter needs to be updated at least once per ~550 seconds in order to avoid a 40-bit SYSTIM timestamp to be misinterpreted as an old timestamp. Since commit 500462a9d ("timers: Switch to a non-cascading wheel"), scheduling of delayed work seems to be less accurate and a requested delay of 540 seconds may actually be longer than 550 seconds. Shorten the delay to 480 seconds to be sure the timecounter is updated in time. This fixes an issue with HW timestamps on 82580/I350/I354 being off by ~1100 seconds for few seconds every ~9 minutes.

2018-10-24ice: Poll for link status changeAnirudh Venkataramanan3-120/+25
When the physical link goes up or down, the driver is supposed to receive a link status event (LSE). The driver currently has the code to handle LSEs but there is no firmware support for this feature yet. So this patch adds the ability for the driver to poll for link status changes. The polling itself is done in ice_watchdog_subtask. For namespace cleanliness, this patch also removes code that handles LSE. This code will be reintroduced once the feature is officially supported.

This also adds the transmit and receive fastpath and interrupt handlers. With this code in place the network device is now able to send and receive frames over the network interface using a single queue.

2018-10-03ixgbe: add AF_XDP zero-copy Tx supportBjörn Töpel3-1/+195
This patch adds zero-copy Tx support for AF_XDP sockets. It implements the ndo_xsk_async_xmit netdev ndo and performs all the Tx logic from a NAPI context. This means pulling egress packets from the Tx ring, placing the frames on the NIC HW descriptor ring and completing sent frames back to the application via the completion ring. The regular XDP Tx ring is used for AF_XDP as well. This rationale for this is as follows: XDP_REDIRECT guarantees mutual exclusion between different NAPI contexts based on CPU id. In other words, a netdev can XDP_REDIRECT to another netdev with a different NAPI context, since the operation is bound to a specific core and each core has its own hardware ring. As the AF_XDP Tx action is running in the same NAPI context and using the same ring, it will also be protected from XDP_REDIRECT actions with the exact same mechanism. As with AF_XDP Rx, all AF_XDP Tx specific functions are added to ixgbe_xsk.c.

2018-10-03ixgbe: add AF_XDP zero-copy Rx supportBjörn Töpel6-21/+745
This patch adds zero-copy Rx support for AF_XDP sockets. Instead of allocating buffers of type MEM_TYPE_PAGE_SHARED, the Rx frames are allocated as MEM_TYPE_ZERO_COPY when AF_XDP is enabled for a certain queue. All AF_XDP specific functions are added to a new file, ixgbe_xsk.c. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack.
