For example, if the VNICC flooding is configured on a qeth device, ethernet frames to unknown destination MAC addresses are received. Currently, there is support for seven VNICCs: flooding, multicast flooding, receive broadcast, learning, takeover learning, takeover setvmac, bridge invisible. Also, six IPA commands exist for configuring VNICCs on a qeth device: query characteristics, query commands, enable characteristic, disable characteristic, set timeout, get timeout. This patch adds the basic code infrastructure for VNICC support to qeth. It allows querying VNICC support from the underlying hardware. To this end, it adds: * basic message formats for IPA commands * basic data structures * basic error handling * query characteristics IPA command support The query characteristics IPA command allows requesting the currently supported and currently enabled VNIC characteristics from the underlying hardware. Support for the other IPA commands and for the configuration of VNICCs is added in follow-up patches together with the respective user interface functions.

These VNICCs are: * Flooding VNICC: Flooding allows specifying if packets to unknown destination MAC addresses are received by the qeth device. * Multicast flooding VNICC: Multicast flooding allows specifying if packets to multicast MAC addresses are received by the qeth device. * Learning VNICC: If learning is enabled on a qeth device, the device learns the source MAC addresses of outgoing packets and incoming packets to those learned MAC addresses are received. * Takeover setvmac VNICC: If takeover setvmac is configured on a qeth device, the MAC address of this device can be configured on a different qeth device with the setvmac IPA command. * Takeover by learning VNICC: If takeover learning is enabled on a qeth device, the MAC address of this device can be learned (learning VNICC) on a different qeth device. * BridgePort invisible VNICC: If BridgePort invisible is enabled on a qeth device, (1) packets from this device are not sent to a BridgePort enabled qeth device and (2) packets coming from a BridgePort enabled qeth device are not received by this device. * Receive broadcast VNICC: Receive broadcast allows configuring if a qeth device receives packets with the broadcast destination MAC address. This patch adds support for the IPA commands that are required to enable and disable these VNIC characteristics on qeth devices. As a prerequisite, it also adds the query commands IPA command. The query commands IPA command allows requesting the supported commands for each characteristic from the underlying hardware. Additionally, this patch provides users with a sysfs user interface to enable/disable the VNICCs mentioned above.

-- cgit v1.2.3 From 349d13d5ab58668ab7c8fadadf292430170c919e Mon Sep 17 00:00:00 2001 From: Hans Wippel Date: Mon, 18 Sep 2017 21:18:16 +0200 Subject: s390/qeth: add VNICC get/set timeout support HiperSockets allow configuring so called VNIC Characteristics (VNICC) that influence how the underlying hardware handles packets. For VNICCs, additional commands for getting and setting timeouts are available. Currently, the learning VNICC uses these commands. * Learning VNICC: If learning is enabled on a qeth device, the device learns the source MAC addresses of outgoing packets and incoming packets to those learned MAC addresses are received. For learning, the timeout specifies the idle period in seconds, after which the underlying hardware removes a learned MAC address again. This patch adds support for the IPA commands that are required to get and set the current timeout values for the learning VNIC characteristic. Also, it introduces the sysfs interface that allows users to configure the timeout. Signed-off-by: Hans Wippel Reviewed-by: Julian Wiedmann Signed-off-by: Julian Wiedmann Signed-off-by: David S.

Adds flag IFF_NAPI that enables these changes and operation is not affected if the flag is disabled. SKBs are constructed upon packet arrival and are queued to be processed later. The new path was evaluated with a benchmark with the following setup: Open two tap devices and a receiver thread that reads in a loop for each device. Start one sender thread and pin all threads to different CPUs. Send 1M minimum UDP packets to each device and measure sending time for each of the sending methods: napi_gro_receive(): 4.90s netif_rx_ni(): 4.90s netif_receive_skb(): 7.20s Signed-off-by: Petar Penkov Cc: Eric Dumazet Cc: Mahesh Bandewar Cc: Willem de Bruijn Cc: davem@davemloft.net Cc: ppenkov@stanford.edu Acked-by: Mahesh Bandewar Signed-off-by: David S.

This mode is available only in TAP mode, as the interface expects packets with Ethernet headers. Furthermore, packets follow the layout of the iovec_iter that was received. The first iovec is the linear data, and every one after the first is a fragment. If there are more fragments than the max number, drop the packet. Additionally, invoke eth_get_headlen() to exercise flow dissector code and to verify that the header resides in the linear data. The napi_gro_frags() mode requires setting the IFF_NAPI_FRAGS option. This is imposed because this mode is intended for testing via tools like syzkaller and packetdrill, and the increased flexibility it provides can introduce security vulnerabilities. This flag is accepted only if the device is in TAP mode and has the IFF_NAPI flag set as well. This is done because both of these are explicit requirements for correct operation in this mode.

Adding active flag to each node - this flag indicates if the object exists in the hardware or not, if not we don't free the hardware resource in error flow. This change will give us the ability to take write lock on the parent node (e.g. FG for FTE creationg) only on the first part.

The most common action is adding a new flow steering entry. In order to enhance the update rate we parallelize the commands by doing the following: 1) Replace the mutex lock with readers-writers semaphore and take the write lock only when necessary (e.g. allocating a new flow table entry index or adding a node to the parent's children list). When we try to find a suitable child in the parent's children list (e.g. search for flow group with the same match_criteria of the rule) then we only take the read lock. 2) Add versioning mechanism - each steering entity (FT, FG, FTE, DST) will have an incremental version. The version is increased when the entity is changed (e.g. when a new FTE was added to FG - the FG's version is increased). Versioning is used in order to determine if the last traverse of an entity's children is valid or a rescan under write lock is required. This support improves the insertion rate of steering rules from ~5k/sec to ~40k/sec.

The basic idea is that we can make use of the fact that the resulting skb must be linear and already comes with a larger headroom for supporting bpf_xdp_adjust_head(), which mangles xdp->data. Here, we base our work on a similar principle and introduce a small helper bpf_xdp_adjust_meta() for adjusting a new pointer called xdp->data_meta. Thus, the packet has a flexible and programmable room for meta data, followed by the actual packet data. struct xdp_buff is therefore laid out that we first point to data_hard_start, then data_meta directly prepended to data followed by data_end marking the end of packet. bpf_xdp_adjust_head() takes into account whether we have meta data already prepended and if so, memmove()s this along with the given offset provided there's enough room. xdp->data_meta is optional and programs are not required to use it. The rationale is that when we process the packet in XDP (e.g. as DoS filter), we can push further meta data along with it for the XDP_PASS case, and give the guarantee that a clsact ingress BPF program on the same device can pick this up for further post-processing. Since we work with skb there, we can also set skb->mark, skb->priority or other skb meta data out of BPF, thus having this scratch space generic and programmable allows for more flexibility than defining a direct 1:1 transfer of potentially new XDP members into skb (it's also more efficient as we don't need to initialize/handle each of such new members). The facility also works together with GRO aggregation. The scratch space at the head of the packet can be multiple of 4 byte up to 32 byte large. Drivers not yet supporting xdp->data_meta can simply be set up with xdp->data_meta as xdp->data + 1 as bpf_xdp_adjust_meta() will detect this and bail out, such that the subsequent match against xdp->data for later access is guaranteed to fail. The verifier treats xdp->data_meta/xdp->data the same way as we treat xdp->data/xdp->data_end pointer comparisons. The requirement for doing the compare against xdp->data is that it hasn't been modified from it's original address we got from ctx access.

Because the IDs are unique but constant for a netdev, any changes are implemented by overwriting the index on NFP. Signed-off-by: John Hurley Signed-off-by: Simon Horman Signed-off-by: David S.

Do a route lookup, determine the next hop entry and update neighbour table on NFP. Monitor the kernel neighbour table for link changes and update NFP with relevant information. Overwrite routes with zero values on the NFP when they expire. Signed-off-by: John Hurley Reviewed-by: Simon Horman Signed-off-by: Simon Horman Signed-off-by: David S.

Update the neighbour entries 'used' value for these IPs next hop. This prevents the neighbour entry from expiring on timeout but rather signals an ARP to verify the connection. From an NFP perspective, packets will not fall back mid-flow unless the link is verified to be down.

The offloading logic has to overcome several obstacles in order to safely comply with the kernel multicast router user API: - It must keep track of the mapping between VIFs to netdevices. The user can add an MFC cache entry pointing to a VIF, delete the VIF and add re-add it with a different netdevice. The offloading logic has to handle this in order to be compatible with the kernel logic. - It must keep track of the mapping between netdevices to spectrum RIFs, as the current hardware implementation assume having a RIF for every port in a multicast router. - It must handle routes pointing to pimreg device to be trapped to the kernel, as the packet should be delivered to userspace. - It must handle routes pointing tunnel VIFs. The current implementation does not support multicast forwarding to tunnels, thus routes that point to a tunnel should be trapped to the kernel. - It must be aware of proxy multicast routes, which include both (*,*) routes and duplicate routes. Currently proxy routes are not offloaded and trigger the abort mechanism: removal of all routes from hardware and triggering the traffic to go through the kernel. The multicast routing offloading logic also updates the counters of the offloaded MFC routes in a periodic work.

The spectrum hardware multicast routes are written using the RMFT2 register and point to an ACL flexible action set. The actions used for multicast routes are: - Counter action, which allows counting bytes and packets on multicast routes. - Multicast route action, which provide RPF check and do the actual packet duplication to a list of RIFs. - Trap action, in the case the route action specified by the called is trap.

By default, multicast MFC routes which are not assigned to any user requested table are put in the RT_TABLE_DEFAULT table. Due to the fact that offloading multicast MFC routes support in Spectrum router logic is going to be introduced soon, squash the default table to MAIN too.

In addition, call the multicast routing upon RIF addition and deletion events. As the multicast routing offload logic may sleep, the actual calls are done in a deferred work. To ensure the MFC object is not freed in that interval, a reference is held to it. In case of a failure, the abort mechanism is used, which ejects all the routes from the hardware and triggers the traffic to flow through the kernel. Note: At that stage, the FIB notifications are still ignored, and will be enabled in a further patch.

This patch fixes it by using a dynamic allocated temporary memory. Because we only do buffer reallocation at init or when setting up the DCB parameter, and priv_buf is only used at buffer allocation process, so it is ok to use a dynamic allocated temporary memory.

It changes after AQ command response is handled in i40e_handle_link_event(). When pf->hw.phy.link_info.link_info is DOWN inside i40e_open(), The state is transient and invalid. So log message gets printed based on incorrect info (i.e link_info and an_info). This commit removes check for unqualified module inside i40e_up_complete(). The existing check in i40e_handle_link_event() logs the error message based on correct link state information.

However in current driver the new state does not get updated when link is going down because of the if condition. When an interface is brought down, vsi->state is set to I40E_VSI_DOWN in i40e_vsi_close() and later i40e_print_link_message() does not get invoked in i40e_link_event due to if condition. Hence link down message doesn't appear when link is going down. The down state is seen later during i40e_open() and old state gets printed. The actual link state doesn't get updated in i40e_close() or i40e_open() but when i40e_handle_link_event is called inside i40e_clean_adminq_subtask. This change allows i40e_print_link_message() to be called when interface is going down and keeps the state information updated.

This led to a design mistake where we open-coded the re-setup of the miscellaneous vector in i40e_resume() instead of using the function provided. If we did not open-code this and instead tried to use the i40e_setup_misc_vector() function, it would lead to never reallocating the IRQ. This would lead to a second i40e_suspend() call failing to free the vector due to a NULL pointer dereference. A future patch is going to re-work how the i40e_suspend() and i40e_resume() flows work to clear all IRQ vectors, which would require us to use i40e_setup_misc_vector() directly. Since during this time the __I40E_RECOVERY_PENDING bit is set, we'll never re-allocate the vector. Rather than leaving the open-coded setup in i40e_resume() lets just fix the problem properly in i40e_setup_misc_vector(). Introduce a new state bit which indicates when the IRQ has been assigned, which will be set when i40e_setup_misc_vector is first called. This ultimately resolves the issue of re-requesting the vector, without overloading the __I40E_RECOVERY_PENDING state. This ensures that the suspend/resume cycle can use the setup function instead of open-coding the re-request during resume. Additionally, since the only callers of i40e_stop_misc_vector also want to free it, move this code directly into the function to avoid duplication. Due to the new functionality, rename it to i40e_free_misc_vector(). This lets us drop the extra calls to free and re-enable the vector during i40e_suspend() and i40e_resume(). We don't need to call i40e_setup_misc_Vector() in i40e_resume() because it gets called by the i40e_rebuild() call.

When hibernating, the system will attempt to migrate all of the vectors back to CPU0 when shutting down all the other CPUs. It is possible that we have so many vectors that it cannot re-assign them to CPU0. This is even more likely if we have many devices installed in one platform. The end result is failure to hibernate, as it is not possible to shutdown the CPUs. We can avoid this by disabling MSI-X and clearing our interrupt scheme when the device is suspended. A more ideal solution would be some method for the stack to properly handle this for all drivers, rather than on a case-by-case basis for each driver to fix itself. However, until this more ideal solution exists, we can do our part and shutdown our IRQs during suspend, which should allow systems with a large number of CPUs to safely suspend or hibernate. It may be worth investigating if we should shut down even further when we suspend as it may make the path cleaner, but this was the minimum fix for the hibernation issue mentioned here. Testing-hints: This affects systems with a large number of CPUs, and with multiple devices enabled. Without this change, those platforms are unable to hibernate at all.

Also in the current implementation, in the case where we have more queues than vectors, we attempt to group the queues together into 'chunks' and map each 'chunk' of queues to a vector. Chunking them together would be more ideal if, and only if, we only had RSS because of the way the hashing algorithm works but in the case of a future patch that enables VF ADq, round robin assignment is better and still works with RSS. This patch resolves both those issues and simplifies the code needed to accomplish this. Instead of treating the case where we have more queues than vectors as special, if we notice our vector index is greater than vectors, reset the vector index to zero and continue mapping. This should ensure that in both cases, whether we have enough vectors for each queue or not, the queues get appropriately mapped.

This patch enables the VF to request a different number of queues allocated to it. This patch also adds a new virtchnl op and capability flag to facilitate this negotiation. After the PF receives a request message, it will set a requested number of queues for that VF. Then when the VF resets, its VSI will get a new number of queues allocated to it. This is a best effort request and since we only allocate a guaranteed default number, if the VF tries to ask for more than the guaranteed number, there may not be enough in HW to accommodate it unless other queues for other VFs are freed. It should also be noted decreasing the number queues allocated to a VF to below the default will NOT enable the allocation of more than 32 VFs per PF and will not free queues guaranteed to each VF by default.

What this patch missed is that we need the PHY to be enabled with bcm_sf2_gphy_enable_set() before probing it on the MDIO bus. This is correctly done in the ops->setup() function, but by the time ops->port_enable() runs, this is too late. Upon unbind we would power down the PHY, and so when we would bind again, the PHY would be left powered off.

This function also checks to make sure we have space to transmit another message. Unfortunately, if we just recently sent a bunch of messages (such as enabling hundreds of VLANs on a VF) this can result in a race where the watchdog task thinks the link went down just because we haven't had time to process all these messages yet. Instead, lets just check whether the mailbox is still open. This ensures that we don't race with the Tx FIFO, and we only link down once the mailbox is not open. This is safe, because if the FIFO fills up and we're unable to send a message for too long, we'll end up triggering the timeout detection which results in a reset. Additionally, since we still check to ensure the mailbox state is OPEN, we'll transition to link down whenever the mailbox closes as well.

We can fix this and avoid false positives. First, we should pass the full buffer size to snprintf, because it guarantees a NULL character as part of its passed length, so passing len-1 is simply wasting a byte of possible storage. Second, if we make the ri and ti variables unsigned, the compiler is able to correctly reason that the value never gets larger than 256, so it doesn't need to warn about the full space required to print a signed integer.

Additionally, the service task isn't scheduled to run automatically until the timer runs out. This causes a needless delay of the first reset to begin talking to the switch manager. We can avoid this by simply not setting last_reset and immediately scheduling the service task while in probe. This allows the device to wake up faster, and avoids this delay.

We read the VFLRE register and reset the VF if the corresponding bit is set, which makes sense. However we loop continuously until we no longer have any bits left unset. At first this makes sense, as a sort of "keep trying until we succeed" concept. Unfortunately this causes a problem if we happen to surprise remove while this code is executing, because in this case we'll always read all 1s for the VFLRE register. This results in a hard lockup on the CPU because the loop will never terminate. Because our own reset function will clear the VFLR event register always, (except when we've lost PCIe link obviously) there is no real reason to loop. In practice, we'll loop over once and find that no VFs are pending anymore. Lets just check once. Since we're clear the notification when we reset there's no benefit to the loop. Additionally, there shouldn't be a race as future VLFRE events should trigger an interrupt. Additionally, we didn't warn or do anything in the looped case anyways.

In this case, the __FM10K_SERVICE_SCHED bit will never be cleared. This results in the service task being unable to reschedule in the future. Add a helper function which sets the service disable bit, waits for the service task to stop and clears the schedule bit, thus avoiding the race condition. We know the schedule bit is safe to clear because the cancel_work_sync() guarantees the service task is not running. Add a helper function also to restart the service task, for symmetry. This is not strictly needed but helps the mental model of how to stop and start the service task. This race could only happen in fm10k_suspend/fm10k_resume as this is the only place where the service task is actually restarted. Thus, suspend/resume testing would be ideal. However, note that the chance of this happening is very slim as the service event is scheduled for immediate execution, and you would have to trigger a suspend at almost the exact same time as the service task was scheduled.

The discovery protocol uses automatically configured control channel (ring 0) and is build on top of request/response transactions using special XDomain primitives provided by the Thunderbolt base protocol. The capabilities consists of a root directory block of basic properties used for identification of the host, and then there can be zero or more directories each describing a Thunderbolt service and its capabilities. Once both sides have discovered what is supported the two hosts can setup high-speed DMA paths and transfer data to the other side using whatever protocol was agreed based on the properties. The software protocol used to communicate which DMA paths to enable is service specific. This patch adds support for the XDomain discovery protocol to the Thunderbolt bus. We model each remote host connection as a Linux XDomain device. For each Thunderbolt service found supported on the XDomain device, we create Linux Thunderbolt service device which Thunderbolt service drivers can then bind to based on the protocol identification information retrieved from the property directory describing the service. This code is based on the work done by Amir Levy and Michael Jamet.

The latter is used by the control channel (ring 0). In frame mode each data frame can hold up to 4kB payload. This patch modifies the DMA ring code to allow configuring a ring to be in frame mode by passing a new flag (RING_FLAG_FRAME) to the ring when it is allocated. In addition there might be need to enable end-to-end (E2E) workaround for the ring to prevent losing Rx frames in certain situations. We add another flag (RING_FLAG_E2E) that can be used for this purpose. This code is based on the work done by Amir Levy and Michael Jamet.

We implement such mode so that the caller can allocate a ring by passing pointer to a function that is then called when an interrupt is triggered. Completed frames can be fetched using tb_ring_poll() and the interrupt can be re-enabled when the caller is finished with polling by using tb_ring_poll_complete().

The protocol consists of configuration phase where each side sends ThunderboltIP login packets (the protocol is determined by UUID in the XDomain packet header) over the configuration channel. Once both sides get positive acknowledgment to their login packet, they configure high-speed DMA path accordingly. This DMA path is then used to transmit and receive networking traffic. This patch creates a virtual ethernet interface the host software can use in the same way as any other networking interface. Once the interface is brought up successfully network packets get tunneled over the Thunderbolt cable to the remote host and back. The connection is terminated by sending a ThunderboltIP logout packet over the configuration channel. We do this when the network interface is brought down by user or the driver is unloaded.

This occurred because we now held the spinlock across a call to i40e_reset_vf(), which results in a usleep_range() call that triggers a scheduling while atomic bug. This was rare as it only occurred if the user configured a VLAN on a VF and also attempted to reconfigure the VF from the host system with a port VLAN. We do need to hold the lock while calling i40e_is_vsi_in_vlan(), but we should not be holding it while we reset the VF. We'll fix this by introducing a separate helper function i40e_vsi_has_vlans which checks whether we have a PVID and whether the VSI has configured VLANs. This helper function will manage its own need for the mac_filter_hash_lock. Then, we can move the acquiring of the spinlock until after we reset the VF, which ensures that we do not sleep while holding the lock. Using a separate function like this makes the code more clear and is easier to read than attempting to release and re-acquire the spinlock when we reset the VF.

The bug exists because we were incorrectly checking the I40E_VF_STATE_PRE_ENABLE bit. When a VF is first init we go through a reset to initialize variables and allocate resources but we don't want to inform clients of this first reset since the client isn't fully enabled yet so we set a state bit signifying we're in a "pre-enabled" client state. During the first reset we should be clearing the bit, allowing all following resets to notify the client of the reset when the bit is not set. This patch fixes the issue by negating the 'test_and_clear_bit' check to accurately reflect the behavior we want.

This unfortunately leaves a lot of things still active, such as the msix_mbx_pf IRQ, and Tx/Rx resources. This can cause problems because the register reads will return potentially invalid values which may result in unknown driver behavior. Begin the process of resetting using fm10k_prepare_for_reset(), much in the same way as the suspend and resume cycle does. This will attempt to shutdown as much as possible, in order to prevent possible issues. A naive implementation for this has issues, because there are now multiple flows calling the reset logic and setting a reset bit. This would cause problems, because the "re-attach" routine might call fm10k_handle_reset() prior to the reset actually finishing. Instead, we'll add state bits to indicate which flow actually initiated the reset. For the general reset flow, we'll assume that if someone else is resetting that we do not need to handle it at all, so it does not need its own state bit. For the suspend case, we will simply issue a warning indicating that we are attempting to recover from this case when resuming. For the detached subtask, we'll simply refuse to re-attach until we've actually initiated a reset as part of that flow. Finally, we'll stop attempting to manage the mailbox subtask when we're detached, since there's nothing we can do if we don't have a PCIe address. Overall this produces a much cleaner shutdown and recovery cycle for a PCIe surprise remove event.

This results in a mailbox timeout, which causes the driver to initiate a reset. During the reset, we re-send all the same messages that originally caused the timeout. This results in a cycle of resets each triggering a future reset. To fix or avoid this, we introduce a workqueue item which monitors a queue of MAC and VLAN requests. These requests are queued to the end of the list, and we process as a FIFO periodically. Initially we only handle requests for the netdev, but we do handle unicast MAC addresses, multicast MAC addresses, and update VLAN requests. A future patch will add support to use this queue for handling MAC update requests from the VF<->PF mailbox. The MAC/VLAN work item will keep checking to make sure that each request does not overflow the mailbox and cause a timeout. If it might, then the work item will reschedule itself a short time later. This avoids any reset cycle, since we never send the message if the mailbox is not ready. As an alternative, we tried increasing the mailbox message FIFO, but this just delays the problem and results in needless memory waste on the system. Our new message queue is dynamically allocated so only uses as much memory as it needs. Additionally, it need not be contiguous like the Tx and Rx FIFOs. Note that this patch chose to only create a queue for MAC and VLAN messages, since these are the only messages sent in a large enough volume to cause the reset loop. Other messages are very unlikely to overflow the mailbox Tx FIFO so easily.

This new handler is very similar to the default code, but uses the MAC/VLAN queue instead of sending the message directly. Unfortunately we can't easily re-use the default code, so we'll just replace the entire function. This ensures that a VF requesting a large number of VLANs or MAC addresses does not start a reset cycle, as explained in the commit which introduced the message queue.

To implement that, add a trap-and-forward ACL action as the last action in the route flexible action set. The used trap is the ACL2 trap, which marks the packets with offload_mr_forward_mark, to prevent the packet from being forwarded again by the kernel. Note: At that stage the offloading logic does not support trap-and-forward multicast routes. This patch adds the support only in the hardware logic.

Especially 802.3ad mode which is very sensitive to these settings. In the current implementation we invoke bond_update_speed_duplex() when we receive NETDEV_UP, however, ignore the return value. If the values we get are invalid (UNKNOWN), then slave gets removed from the aggregator with speed and duplex set to UNKNOWN while link is still marked as UP. This patch fixes this scenario. Also 802.3ad mode is sensitive to these conditions while other modes are not, so making sure that it doesn't change the behavior for other modes.

This of course has no implication on the channel width but still sends a command to the firmware. Remember the last width that was sent and refrain from sending unnecessary commands to the firmware. Sending a PHY_CTXT_CMD to the firmware has a cost since it recalculates the presence on the medium and because of that it closes the transmit queues for a short while.

Add some debug information and attempt to dump the different register spaces at such a failure: * Dump some configuration space of device - this will tell us if something very basic is broken in the PCIe bus (so that configuration accesses are failing). If this works, the PCIe bus seems OK. If this does not work, it is definitely an PCIe issue. * Dump some memory mapped registers - if we're reading some sane'ish values, this will tell us that the PCIe bus is OK, but may be a firmware / driver issue. If this does not work, it may be a PCI configuration issue or a driver/firmware issue. * Dump parent and device's AER registers, will give us some straws to chew on.

To improve this, introduce a new function to get an ACPI object by invoking an ACPI method that can be reused. Additionally, since this function needs to be called when we only have the trans, the opmode or the device, introduce a new debug macro that gets the device as a parameter so it can be used in the new function.

Meaning a loop iterates on v_idx, which is an incremental value, and the cpumask is created based on this value. This is a problem in systems with multiple logical CPUs per core (like in simultaneous multithreading (SMT) scenarios). If we disable some logical CPUs, by turning SMT off for example, we will end up with a sparse cpu_online_mask, i.e., only the first CPU in a core is online, and incremental filling in q_vector cpumask might lead to multiple offline CPUs being assigned to q_vectors. Example: if we have a system with 8 cores each one containing 8 logical CPUs (SMT == 8 in this case), we have 64 CPUs in total. But if SMT is disabled, only the 1st CPU in each core remains online, so the cpu_online_mask in this case would have only 8 bits set, in a sparse way. In general case, when SMT is off the cpu_online_mask has only C bits set: 0, 1*N, 2*N, ..., C*(N-1) where C == # of cores; N == # of logical CPUs per core. In our example, only bits 0, 8, 16, 24, 32, 40, 48, 56 would be set. Instead, we should only assign hints for CPUs which are online. Even better, the kernel already provides a function, cpumask_local_spread() which takes an index and returns a CPU, spreading the interrupts across local NUMA nodes first, and then remote ones if necessary. Since we generally have a 1:1 mapping between vectors and CPUs, there is no real advantage to spreading vectors to local CPUs first. In order to avoid mismatch of the default XPS hints, we'll pass -1 so that it spreads across all CPUs without regard to the node locality. Note that we don't need to change the q_vector->affinity_mask as this is initialized to cpu_possible_mask, until an actual affinity is set and then notified back to us.

This behaviour is correct. Afterwards existing filter can be removed making free slot for the new one. This however causes the newly added filter to be accepted by firmware but removed from driver filter list resulting in not showing after issuing 'ethtool -n '. This happened due to not clearing the variable pf->fd_inv which stores filter number to be removed from the list when firmware refused to add the requested filter. It caused the filter with this specific ID to be constantly removed once it was added to the list although it has been accepted by firmware and effectively applied to the NIC. It was fixed by clearing pf->fd_inv variable after removal of the filter from the list when it was rejected by firmware.

This should have allowed VFs to disable the feature. Unfortunately, the flag was set only in netdev->feature flags and not in netdev->hw_features. This ultimately causes the stack to assume that it cannot change the flag, so it was unchangeable and marked as [fixed] in the ethtool -k output. Fix this by setting the feature in hw_features first, just as we do for the PF code. This enables ethtool -K to disable the feature correctly, and fully enables user control of the VLAN tag stripping feature.

This same logic was refactored in commit 1dc8b538795f ("i40e: Reorder logic for coalescing RS bits"), but ultimately was not functionally changed. Using skb->xmit_more in this way is incorrect, because in certain circumstances we may see a large number of skbs in sequence with xmit_more set. This leads to a performance loss as the hardware does not writeback anything for those packets, which delays the time it takes for us to respond to the stack transmit requests. This significantly impacts UDP performance, especially when layered with multiple devices, such as bonding, VLANs, and vnet setups. This was not noticed until now because it is difficult to create a setup which reproduces the issue. It was discovered in a UDP_STREAM test in a VM, connected using a vnet device to a bridge, which is connected to a bonded pair of X710 ports in active-backup mode with a VLAN. These layered devices seem to compound the number of skbs transmitted at once by the qdisc. Additionally, the problem can be masked by reducing the ITR value. Since the original commit does not provide strong justification for this RS bit "optimization", revert to the previous behavior of setting the RS bit every 4th packet.

Since we don't yet have more than 32 flags, we'll use a u32 for both the hw_features and flag field. Should we gain more flags in the future, we may need to convert to a u64 or separate flags out into two fields. One alternative approach considered, but not implemented here, was to use an enumeration for the flag variables, and create a macro I40E_FLAG() which used string concatenation to generate BIT_ULL values. This has the advantage of making the actual bit values compile-time dynamic so that we do not need to worry about matching the order to the bit value. However, this does produce a high level of code churn, and makes it more difficult to read a dumped flags value when debugging.

This was a problem when the irq is described as a GpioInt rather then an Interrupt in the DSDT as for GpioInt-s the value passed to request_irq is honored. This commit fixes this by requesting the correct trigger type depending on bcm_device.irq_polarity. 2) bcm_device.irq_polarity was used to directly store an ACPI polarity value (ACPI_ACTIVE_*). This is undesirable because hci_bcm is also used with device-tree and checking for something like ACPI_ACTIVE_LOW in a non ACPI specific function like bcm_request_irq feels wrong. This commit fixes this by renaming irq_polarity to irq_active_low and changing its type to a bool.

Previously both Tx and Rx rings were cleared in a rx_desc->wb.upper.length based loop which could lead to issues if for w/e reason packets were received outside of the frames transmitted for the loopback test. - Add check for IXGBE_TXD_STAT_DD to avoid clearing the rings if the transmits have not comlpeted by the time we enter ixgbe_clean_test_rings() - Exit early on ixgbe_check_lbtest_frame() failure. This change fixes a crash during ethtool diagnostic (ethtool -t).

We also have strict restrictions on which GPRs we can use. Only GPRs 0-23 are reserved for BPF. Adjust the static register locations and "ABI" registers. Note that packet length is packed with other info so we have to extract it into one of the scratch registers, OTOH since LMEM can be used in restricted operands we don't have to extract packet pointer.

Based on the refcnt, the driver can determine if the RX-page is currently only used by a single packet, if so it can then directly refill/recycle the RX-slot by with the opposite "side" of the page. While this is a clever trick, it is hard to determine when this recycling is successful and when it fails. Adding a counter, which is available via ethtool --statistics as 'alloc_rx_page'. Which counts the number of times the recycle fails and the real page allocator is invoked. When interpreting the stats, do remember that every alloc will serve two packets. The counter is collected per rx_ring, but is summed and ethtool exported as 'alloc_rx_page'. It would be relevant to know what rx_ring that cannot keep up, but that can be exported later if someone experience a need for this.

Specifically with this change what I have done is make it so that our ITR algorithm will try to prevent either starving a socket buffer for memory in the case of Tx, or overrunning an Rx socket buffer on receive. In addition a side effect of the calculations used is that we should function better with new features such as XDP which can handle small packets at high rates without needing to lock us into NAPI polling mode.

In some cases, an additional packet will arrive which will complete the alignment of a fpdu, but we won't be able to post the fpdu due to insufficient place on the tx ring. In this case we can't loose the data and require storing it for later. Processing is therefore done in two places, during rx completion, where we initialize a mpa buffer descriptor and add it to the pending list, and during tx-completion, since we free up an entry in the tx chain we can process any pending mpa packets. The mpa buff descriptors are pre-allocated since we have to ensure that we won't reach a state where we can't store an incoming unaligned packet. All packets received on the ll2 MUST be processed by the driver at some stage. Since they are preallocated, we hold a free list.

Each connection stores the current status of the connection: either nothing pending, or there is a partial fpdu that is waiting for the rest of the fpdu (incomplete bytes != 0). The same structure is also used for splitting a packet when there are packed fpdus. The structure is initialized with all data required for sending the fpdu back to the FW. A fpdu will always be spanned across a maximum of 3 tx bds. One for the header, one for the partial fdpu received and one for the remainder (unaligned) packet. In case of packed fpdu's, two fragments are used, one for the header and one for the data. Corner cases are not handled in the patch for clarity, and will be added as a separate patch.

This cookie is the ll2 iwarp buffer which is then reposted to the rx ring. Part of the unaligned mpa flow is determining when a buffer can be reposted. Each buffer needs to be sent only once as a cookie for on the tx ring. In packed fpdu case, only the last packet will be sent with the buffer, meaning we need to handle the case that a cookie can be NULL on tx complete. In addition, when a fpdu splits over two buffers, but there are no more fpdus on the second buffer, two buffers need to be provided as a cookie. To avoid changing the ll2 interface to provide two cookies, we introduce a piggy buf pointer, relevant for iWARP only, that holds a pointer to a second buffer that needs to be released during tx completion.

Since both use module_init() thunderbolt-net ends up calling Thunderbolt bus functions too early triggering the above crash. Fix this by moving Thunderbolt bus initialization to happen earlier to make sure all the data structures are ready when Thunderbolt service drivers are initialized. To be on the safe side also add a check for properly initialized xdomain_property_dir to tb_register_property_dir().

The events are as such: - filter marked for removal - same filter is re-added before watchdog that cleans up filters - we skip re-adding the filter because we have it already in the list - watchdog filter cleanup kicks off and filter is removed So when we were re-adding the same filter, it didn't actually get added because it already existed in the list, but was marked for removal and had yet to actually be removed. This patch fixes the issue by making sure that when adding a filter, if we find it already existing in our list, make sure it is not marked to be removed.

Effectively the driver defaults to an ITR value of half the expected value (in terms of minimum microseconds between interrupts). Fix this by changing the default values to be calculated using ITR_REG_TO_USEC macro which indicates that we're converting from the register units into microseconds.

According to empirical testing this isn't the case. Additionally, the data sheet specifically says that we should set the CLEARPBA bit when re-enabling interrupts in a polling setup.

Counter intuitively, empirical testing has shown that decreasing this value from 2 to 1, and thus changing from an immediate interrupt at fewer than 128 descriptors down to 64 descriptors causes a small increase in the maximum total packets per second we can receive. This increase occurs even when we're polling with interrupts masked, as the hardware must still handle interrupts internally even if we've disabled them in software. Also reduce the value for any VFs we allocate.

Thus, it is pointless to bump tail by an unaligned access as the hardware will ignore some of the new descriptors we allocated. Thus, it's ideal if we can ensure tail writes are always aligned to 8. At first, it seems like we'd already do this, since we allocate descriptors in batches which are a multiple of 8. Since we'd always increment by a multiple of 8, it seems like the value should always be aligned. However, this ignores allocation failures. If we fail to allocate a buffer, our tail register will become unaligned. Once it has become unaligned it will essentially be stuck unaligned until a buffer allocation happens to fail at the exact amount necessary to re-align it. We can do better, by simply rounding down the number of buffers we're about to allocate (cleaned_count) such that "next_to_clean + cleaned_count" is rounded to the nearest multiple of 8. We do this by calculating how far off that value is and subtracting it from the cleaned_count. This essentially defers allocation of buffers if they're going to be ignored by hardware anyways, and re-aligns our next_to_use and tail values after a failure to allocate a descriptor. This calculation ensures that we always align the tail writes in a way the hardware expects and don't unnecessarily allocate buffers which won't be fetched immediately.

Empirical testing has shown that we reduce CPU utilization and don't appear to reduce throughput or packet rate. 32 seems to be the sweet spot, as it's half the default polling budget, so we'd essentially reduce from 4 tail writes when polling down to 2. Increasing this up to 64 appears to have negative impacts as it may become possible that we don't bump the tail each time we get polled, which could cause a long delay between returning descriptors to the hardware.

When reached, transmission stalls. Stalls cause latency, as well as head-of-line blocking of other flows that do not use zerocopy. Instead of stalling, revert to copy-based transmission. Tested by sending two udp flows from guest to host, one with payload of VHOST_GOODCOPY_LEN, the other too small for zerocopy (1B). The large flow is redirected to a netem instance with 1MBps rate limit and deep 1000 entry queue. modprobe ifb ip link set dev ifb0 up tc qdisc add dev ifb0 root netem limit 1000 rate 1MBit tc qdisc add dev tap0 ingress tc filter add dev tap0 parent ffff: protocol ip \ u32 match ip dport 8000 0xffff \ action mirred egress redirect dev ifb0 Before the delay, both flows process around 80K pps. With the delay, before this patch, both process around 400. After this patch, the large flow is still rate limited, while the small reverts to its original rate. See also discussion in the first link, below. Without rate limiting, {1, 10, 100}x TCP_STREAM tests continued to send at 100% zerocopy. The limit in vhost_exceeds_maxpend must be carefully chosen. With vq->num >> 1, the flows remain correlated. This value happens to correspond to VHOST_MAX_PENDING for vq->num == 256.

Unfortunately, when the corresponding change to the ACPI code lands (a change that will stop enumerating and registering the serial-device-node child as a platform device) PM will break silently unless serdev TTY-port controller support has been enabled. Specifically, hciattach (btattach) would still succeed, but power management would no longer work. Although this is strictly a runtime dependency, let's make the driver depend on SERIAL_DEV_CTRL_TTYPORT, which is the particular serdev controller implementation used by the ACPI devices currently managed by this driver, to avoid breaking PM without anyone noticing. Note that the driver already has a (build-time) dependency on the serdev bus code.

This is a double problem because 1) at the moment e1000_msix_other() assumes that it is only called in case of Link Status Change and 2) if the condition persists, the interrupt is repeatedly raised again in quick succession. Ideally we would configure the Other interrupt to not be raised in case of receiver overrun but this doesn't seem possible on this adapter. Instead, we handle the first part of the problem by reverting to the practice of reading ICR in the other interrupt handler, like before commit 16ecba59bc33 ("e1000e: Do not read ICR in Other interrupt"). Thanks to commit 0a8047ac68e5 ("e1000e: Fix msi-x interrupt automask") which cleared IAME from CTRL_EXT, reading ICR doesn't interfere with RxQ0, TxQ0 interrupts anymore. We handle the second part of the problem by not re-enabling the Other interrupt right away when there is overrun. Instead, we wait until traffic subsides, napi polling mode is exited and interrupts are re-enabled.

I219LM and I219V devices can fall into unrecovered Tx hang under very stressfully UDP traffic and multiple reconnection of Ethernet cable. This Tx hang of the LAN Controller is only recovered if the system is rebooted. Slightly slow down DMA access by reducing the number of outstanding requests. This workaround could have an impact on TCP traffic performance on the platform. Disabling TSO eliminates performance loss for TCP traffic without a noticeable impact on CPU performance.

We need to configure the SYSTEMPORT transmit queue with the switch port number and switch port queue number in order for the switch and SYSTEMPORT hardware to utilize the out of band congestion notification. This hardware mechanism works by looking at the switch port egress queue and determines whether there is enough buffers for this queue, with that class of service for a successful transmission and if not, backpressures the SYSTEMPORT queue that is being used. For this to work, we implement a notifier which looks at the DSA_PORT_REGISTER event. When DSA network devices are registered, the framework calls the DSA notifiers when that happens, extracts the number of queues for these devices and their associated port number, remembers that in the driver private structure and linearly maps those queues to TX rings/queues that we manage. This scheme works because DSA slave network deviecs always transmit through SYSTEMPORT so when DSA slave network devices are destroyed/brought down, the corresponding SYSTEMPORT queues are no longer used. Also, by design of the DSA framework, the master network device (SYSTEMPORT) is registered first. For faster lookups we use an array of up to DSA_MAX_PORTS * number of queues per port, and then map pointers to bcm_sysport_tx_ring such that our ndo_select_queue() implementation can just index into that array to locate the corresponding ring index.

Firmware will send channel statistics for each channel in the request. This will be stored in chan_stats array. Few channels might report hidden SSIDs in passive scan results. So, once the original scan request is finished, driver issues an active scan request for all channels which reported hidden SSIDs. This will cause duplicates in the chan_stats array. At worst, every channel will have a hidden SSID, in which case the driver can issue active scan requests for each channel. So the complete scan statistics size will be twice of existing limit. At present maximum number of channels returned in scan statistics is 31(BG) + 14(A) = 45. Clearly there will be an overflow of the chan_stats array in the above mentioned scenario. To fix this double the size of chan_stats array.

This has particularly bad effects for some platforms, because we don't stop the power-save timer, and if this timer goes off after the PCI controller has suspended the link, Bad Things will happen. Commit 32faa3f0ee50 ("ath10k: add the PCI PM core suspend/resume ops") got some of this right, in that it understood there was a problem on non-WoWLAN firmware. But it forgot the $subject case. Fix this by moving all the PCI driver suspend/resume logic exclusively into the driver PM hooks. This shouldn't affect WoWLAN support much (this just gets executed later on). I would just as well kill the entirety of ath10k_hif_suspend(), as it's not even implemented on the USB or SDIO drivers. I expect that we don't need the callback, except to return "supported" (i.e., 0) or "not supported" (i.e., -EOPNOTSUPP).

A new channel is created for each of the traffic class configuration offloaded via mqprio framework except for the first TC (TC0). TC0 for the main VSI is also reconfigured as per user provided queue parameters. Queue counts that are not power-of-2 are handled by reconfiguring RSS by reprogramming LUTs using the queue count value. This patch also handles configuring the TX rings for the channels, setting up the RX queue map for channel. Also, the channels so created are removed and all the queue configuration is set to default when the qdisc is detached from the root of the device.

In this mode, the priority to traffic class mapping and the user specified queue ranges are used to configure the traffic classes by setting the mode option to 'channel'. Example: map 0 0 0 0 1 2 2 3 queues 2@0 2@2 1@4 1@5\ hw 1 mode channel qdisc mqprio 8038: root tc 4 map 0 0 0 0 1 2 2 3 0 0 0 0 0 0 0 0 queues:(0:1) (2:3) (4:4) (5:5) mode:channel shaper:dcb The HW channels created are removed and all the queue configuration is set to default when the qdisc is detached from the root of the device. This patch also disables setting up channels via ethtool (ethtool -L) when the TCs are configured using mqprio scheduler. The patch also limits setting ethtool Rx flow hash indirection (ethtool -X eth0 equal N) to max queues configured via mqprio. The Rx flow hash indirection input through ethtool should be validated so that it is within in the queue range configured via tc/mqprio. The bound checking is achieved by reporting the current rss size to the kernel when queues are configured via mqprio.

After another commit to add support for the BCM UART connected BT ACPI-id BCM2E7E used on the GPD win, it turns out that the BT on the GPD pocket is connected via both USB and UART. Adding support for the BCM2E7E ACPI-id causes it to switch to UART mode. The Windows shipped with the device is using it in UART mode and the presence of the BCM2E7E ACPI-id combined with the all 0 USB vid:pid indicates that the BT part was never meant to be used in USB mode. With the recent patches to use serdev device enumeration / instantiation for UART attached ACPI enumerated BT devices, everything work OOTB in UART mode and the workaround for the all 0 USB vid:pid is no longer needed.

Verifier/parser logic needs to record pointer type. Note that although verifier does protect us from CTX vs other pointer changes we will also want to differentiate between PACKET vs MAP_VALUE or STACK, so we can add the check already.

This movement involves the following changes: - Change mlx5e_ prefix to be mlx5_ - Add clock structs to Core - Add clock object to mlx5_core_dev - Call Init/Uninit clock from core init/cleanup - Rename mlx5e_tstamp to be mlx5_clock Signed-off-by: Feras Daoud Signed-off-by: Eitan Rabin Signed-off-by: Saeed Mahameed --- drivers/net/ethernet/mellanox/mlx5/core/en.h | 39 +- .../net/ethernet/mellanox/mlx5/core/en_ethtool.c | 7 +- drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 95 +++- drivers/net/ethernet/mellanox/mlx5/core/en_rx.c | 17 +- drivers/net/ethernet/mellanox/mlx5/core/en_tx.c | 6 +- drivers/net/ethernet/mellanox/mlx5/core/eq.c | 3 +- .../net/ethernet/mellanox/mlx5/core/ipoib/ipoib.c | 3 +- .../net/ethernet/mellanox/mlx5/core/lib/clock.c | 548 +++++++++------------ .../net/ethernet/mellanox/mlx5/core/lib/clock.h | 51 ++ drivers/net/ethernet/mellanox/mlx5/core/main.c | 4 + .../net/ethernet/mellanox/mlx5/core/mlx5_core.h | 1 + include/linux/mlx5/driver.h | 24 + 12 files changed, 416 insertions(+), 382 deletions(-) create mode 100644 drivers/net/ethernet/mellanox/mlx5/core/lib/clock.h (limited to 'drivers') diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en.h b/drivers/net/ethernet/mellanox/mlx5/core/en.h index cc13d3dbd366..2059122eb089 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/en.h +++ b/drivers/net/ethernet/mellanox/mlx5/core/en.h @@ -267,28 +267,6 @@ struct mlx5e_dcbx { };

Now using a linked list multiple QPNs can be attached to the same FT. Supporting attaching multiple underlay QPs is required for PKEY support in which child and parent share the same FT. The actual attaching/detaching FW commands will be called inside the function symmetrically. This change requires a change in IPoIB open and close functions, the attaching/detaching to/from the FT is done each time we open/close.

The issue appears to be that one copy was delivered based on the source MAC address and then the second copy was being delivered based on the destination MAC address. To fix it I am just treating a unicast address match as though it is not a match since source based macvlan isn't supposed to be matching based on the destination MAC anyway.

But that's never true for IPv6 overlays, and is not true for IPv4 ones either, if net.ipv4.conf.*.rp_filter is unset. To support decap-only tunnels, an IPIP entry is now created as soon as an offloadable tunneling device is created. When that netdevice is up'd, a decap route is looked up and possibly offloaded. Thus decap is not handled implicitly as part of mlxsw_sp_ipip_entry_get() call anymore, but needs to be done explicitly after the get, if desired.

However now that they are created eagerly as a reaction to events on such netdevices, the reference counting is useless. Hence drop it. The routes whose next hops reference an offloaded IP-in-IP netdevice actually linger around a bit after their device is unregistered. However, mlxsw_sp_ipip_entry_destroy() also destroys the backing loopback, and mlxsw_sp_rif_destroy() transitively (via mlxsw_sp_nexthop_rif_gone_sync()) calls mlxsw_sp_nexthop_ipip_fini(), which unlinks the IPIP entry from a next hop.

This is problematic because eventually they will be removed and they only support 32 bits of PHY types. This overhauls i40e_phy_type_to_ethtool to use only the new API. Doing this also allows us to provide much better support for newer 25G and 10G PHY types which is included here as well. The remaining usages of the old ethtool API will be addressed in other patches in the series.

The new API also allows us to provide more explicit support for new 25G and 10G PHY types so some of the PHY types have been adjusted where necessary as well.

Other speeds require 25MHz or higher. This patch configures a 100MHz clock if the system has a direct-attached PHY, or 25MHz if the system is running NC-SI which is limited to 100MHz. There appear to be no other upstream users of the FTGMAC100 driver it is hard to know the clocking requirements of other platforms. Therefore a conservative approach was taken with enabling clocks. If the platform is not ASPEED, both requesting the clock and configuring the speed is skipped. Signed-off-by: Joel Stanley Tested-by: Andrew Jeffery Signed-off-by: David S.

It is OK and sometimes necessary for the DSA drivers to access this data, but this has to be read only. For that purpose, add a dsa_to_port() helper which returns a const pointer to a dsa_port structure which must be used by DSA drivers from now on instead of digging into ds->ports[] themselves.

Setting pdev->dev.of_node with the MAC node triggers the MAC driver probing of the new platform device. While this fails quickly and does not affect the functionality of the drivers, it is incorrect and must be removed.

Besides making the names more aligned, this allows writing udev rules that match on either driver name, if needed, using the fsl_dpaa_* prefix. The change of netdev dev required for the DSA probing makes the previous rules written using this prefix fail, this change makes them work again, ensuring backwards compatibility for their users.

The reason for reverting this is because the original patch no longer fixes what it previously did as the underlying structure has changed for macvtap. Specifically macvtap originally pulled packets directly off of the lowerdev. However in commit 6acf54f1cf0a ("macvtap: Add support of packet capture on macvtap device.") that code was changed and instead macvtap would listen directly on the macvtap device itself instead of the lower device. As such, the L2 forwarding offload should now be able to provide a performance advantage of skipping the checks on the lower dev while not introducing any sort of regression.

In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme is being adopted for drivers for Renesas SoCs. Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The approach that has been consistently taken for other IP blocks is to name common code, compatibility strings and so on after R-Car Gen2.

Also: 1) we don't do such validation for any of the other netdev_ops routines. 2) the code in question clearly has never been actually exercised; it's broken. After determining that the device is not owned by qeth, it would still use dev->ml_priv to write a qeth trace entry. Remove the check, and its helper that walked the global card list.

The address validation is not done for addresses received from router advertisements. Handling RAs in softirq context is the only reason for the notifier chain to be atomic versus blocking. Since the only current user, ipvlan, of the validator chain ignores softirq context, the notifier can be made blocking and simply not invoked for softirq path. The blocking option is needed by spectrum for example to validate resources for an adding an address to an interface. Signed-off-by: David Ahern Reviewed-by: Ido Schimmel Signed-off-by: David S.

This is important since overflows and underflows can lead to use-after-free situation and be exploitable. The variable cn_callback_entry.refcnt is used as pure reference counter.

Also populate the slice number that should be used (slice 1 for IPv4) based on the lookup function. Finally, we introduce two helper functions: udf_upper_bits() and udf_lower_bits() to help setting the UDF_n_* valid bits based on the number of UDFs valid within a slice. Update the IPv4 rule setting to make use of it to be more robust wrt. change in number of User Defined Fields being programmed. Signed-off-by: Florian Fainelli Signed-off-by: David S.

When non-equal-cost multi-path support will be introduced, the group's size will help users understand the exact number of adjacency entries each nexthop occupies, as a nexthop will no longer correspond to a single entry. The output for a multi-path route with two nexthops, one with weight 255 and the second 1 will be: Example: $ devlink dpipe table dump pci/0000:01:00.0 name mlxsw_adj pci/0000:01:00.0: index 0 match_value: type field_exact header mlxsw_meta field adj_index value 65536 type field_exact header mlxsw_meta field adj_size value 512 type field_exact header mlxsw_meta field adj_hash_index value 0 action_value: type field_modify header ethernet field destination mac value e4:1d:2d:a5:f3:64 type field_modify header mlxsw_meta field erif_port mapping ifindex mapping_value 3 value 1 index 1 match_value: type field_exact header mlxsw_meta field adj_index value 65536 type field_exact header mlxsw_meta field adj_size value 512 type field_exact header mlxsw_meta field adj_hash_index value 510 action_value: type field_modify header ethernet field destination mac value e4:1d:2d:a5:f3:65 type field_modify header mlxsw_meta field erif_port mapping ifindex mapping_value 4 value 2 Thus, the first nexthop occupies 510 adjacency entries and the second 2, which leads to a ratio of 255 to 1.

The boundaries of each partition as well as their allocation size are represented using defines. This representation requires us to patch all the functions that act on a partition whenever the partitioning scheme is changed. In addition, it does not enable the dynamic configuration of the KVDL using the up-coming resource manager. Add objects to represent these partitions as well as the accompanying code that acts on them to perform allocations and de-allocations. In the following patches, this will allow us to easily add another partition as well as new operations to act on these partitions.

This works because existing users (e.g., router) request the exact number they end up using. With the introduction of large adjacency groups, this will change, as the router will have the ability to choose from several allocation sizes, where larger allocations provide higher accuracy with respect to requested weights and better resilience against nexthop failures. One option is to have the router try several allocations of descending size until one succeeds, but a better way is to simply allow it to query the actual allocation size and then size its request accordingly.

This patch takes the `weight` parameter into account and populates the adjacency group according to the relative weight of each nexthop. Specifically, the weights of all the nexthops that should be offloaded are first normalized and then used to calculate the upper adjacency index of each nexthop. This is done according to the hash-threshold algorithm used by the kernel for IPv4 multi-path routing. Adjacency groups are currently limited to 32 entries which limits the weights that can be used, but follow-up patches will introduce groups of 512 entries.

Unaligned accesses to LMEM are not allowed. Accesses also have to be 4B wide. To support stack we need to make sure offsets of pointers are known at translation time (for now) and perform correct load/mask/shift operations. Since we can access first 64B of LMEM without much effort support only stacks not bigger than 64B. Following commits will extend the possible sizes beyond that.

Add a function for encoding local CSR access instruction. Use stack pointer number 3. Note that stack pointer registers allow us to index into 32 bytes of LMEM (with shift operations i.e. when operands are restricted). This means if access is crossing 32 byte boundary we must not use offsetting, we have to set the pointer to the exact address and move it with post-increments. We depend on the datapath placing the stack base address in GPR A22 for our use. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: David S.

If the 32bit halves of the 64bit constant are the same, however, we can save a cycle by doing a register move instead of two loads of 16 bits. Note that we don't optimize the normal ALU64 load because even though it's a 64 bit load the upper half of the register is a coming from sign extension so we can load it in one cycle anyway.

It was discovered that this condition was not being met when connected to an external RGMII PHY that disabled the Rx clock in the Power Save state. This commit modifies the reset_umac function to place the (RG)MII interface into a local loopback mode where the Rx clock comes from the GENET sourced Tx clk during the sw_reset to ensure the presence and stability of the clock. In addition, it turns out that the sw_reset of the UniMAC is not self clearing, but this was masked by a bug in the timeout code. The sw_reset is now explicitly cleared by zeroing the UMAC_CMD register before returning from reset_umac which makes it no longer necessary to do so in init_umac and makes the clearing of CMD_TX_EN and CMD_RX_EN by umac_enable_set redundant. The timeout code (and its associated bug) are removed so reset_umac no longer needs to return a result, and that means init_umac that calls reset_umac does not need to as well.

For some unknown reason the LAN9303 switch fail to forward data when switch fabric port 0 TX is disabled during probe. (Write of LAN9303_MAC_TX_CFG_0 in lan9303_disable_processing_port().) In that situation the switch fabric seem to receive frames, because the ALR is learning addresses. But no frames are transmitted on any of the ports. In our system lan9303_probe() is called twice, first time dsa_register_switch() return -EPROBE_DEFER. As an experiment, modified the code to skip writing LAN9303_MAC_TX_CFG_0, port 0 during the first probe. Then the switch works as expected. Resolve the problem by not calling lan9303_disable_processing_port() on port 0 during probe. Ports 1 and 2 are still disabled. Although unsatisfying that the exact failure mechanism is not known, the patch should not cause any harm. Signed-off-by: Egil Hjelmeland Reviewed-by: Andrew Lunn Signed-off-by: David S.

The idea with these sequence numbers is that the responding host uses the same sequence number that was in the request packet which we can then check at the requesting host. However, testing against macOS it looks like it does not follow this but instead uses some other logic. Windows driver on the other hand handles it the same way than Linux. In order to be able to talk to macOS again, fix this so that we drop the whole sequence number check. This effectively works exactly the same than it worked before the aforementioned commit. This also follows the logic the original P2P networking code used. Signed-off-by: Mika Westerberg Signed-off-by: David S.

But using ds->enabled_port_mask is misleading, because this mask reports in fact the user ports. To avoid confusion and fix this, this patch introduces an explicit dsa_is_unused_port helper which ensures the corresponding bit is not masked in any of the switch port masks.

-- cgit v1.2.3 From f8503969d27b2b26ff0adbce4b7d7cf4ba5e43c2 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Thu, 26 Oct 2017 11:51:28 -0400 Subject: bnxt_en: Refactor and simplify coalescing code. The mapping of the ethtool coalescing parameters to hardware parameters is now done in bnxt_hwrm_set_coal_params(). The same function can handle both RX and TX settings. The code is now more clear. Some adjustments have been made to get better hardware settings. The coal_frames setting is now accurately set in hardware. The max_timer is set to coal_ticks value.

For vxlan encap, the driver maintains a tunnel encap hash-table. When a new flow with a tunnel encap action arrives, this table is looked up; if an encap entry exists, it uses the already programmed encap_record_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new encap node is added and the L2 header fields are queried via a route lookup. hwrm_cfa_encap_record_alloc cmd is used to create a new encap record and the encap_record_handle is used as the tunnel_handle while adding the flow. For vxlan decap, the driver maintains a tunnel decap hash-table. When a new flow with a tunnel decap action arrives, this table is looked up; if a decap entry exists, it uses the already programmed decap_filter_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new decap node is added and a decap_filter_handle is alloc'd via the hwrm_cfa_decap_filter_alloc cmd. This handle is used as the tunnel_handle while adding the flow. The code to issue the HWRM FW cmds is introduced in a follow-up patch. Signed-off-by: Sathya Perla Signed-off-by: Michael Chan Signed-off-by: David S.

-- cgit v1.2.3 From 05f9d3e1ae6eaf7507e3bd95b0eef2acd4b84ea8 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Mon, 16 Oct 2017 18:01:28 -0700 Subject: igb: Add support for CBS offload This patch adds support for Credit-Based Shaper (CBS) qdisc offload from Traffic Control system. This support enable us to leverage the Forwarding and Queuing for Time-Sensitive Streams (FQTSS) features from Intel i210 Ethernet Controller. FQTSS is the former 802.1Qav standard which was merged into 802.1Q in 2014. It enables traffic prioritization and bandwidth reservation via the Credit-Based Shaper which is implemented in hardware by i210 controller. The patch introduces the igb_setup_tc() function which implements the support for CBS qdisc hardware offload in the IGB driver. CBS offload is the only traffic control offload supported by the driver at the moment. FQTSS transmission mode from i210 controller is automatically enabled by the IGB driver when the CBS is enabled for the first hardware queue. Likewise, FQTSS mode is automatically disabled when CBS is disabled for the last hardware queue. Changing FQTSS mode requires NIC reset. FQTSS feature is supported by i210 controller only.

See this thread for context: https://www.spinics.net/lists/netdev/msg217665.html My specific case is that: We have many computers with gigabit Realtek NICs. For 2 such computers connected to a gigabit store-and-forward switch the minimum round-trip time for small pings (`ping -i 0 -w 3 -s 56 -q peer`) is ~ 30μs. However it turned out that when Ethernet frame length transitions 127 -> 128 bytes (`ping -i 0 -w 3 -s {81 -> 82} -q peer`) the lowest RTT transitions step-wise to ~ 270μs. As David Light said this is RX interrupt mitigation done by NIC which creates the latency. For workloads when low-latency is required with e.g. Intel, BCM etc NIC drivers one just uses `ethtool -C rx-usecs ...` to reduce the time NIC delays before interrupting CPU, but it turned out `ethtool -C` is not supported by r8169 driver. Like Stéphane ANCELOT I've traced the problem down to IntrMitigate being hardcoded to != 0 for our chips (we have 8168 based NICs): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/realtek/r8169.c#n5460 static void rtl_hw_start_8169(struct net_device *dev) { ... /* * Undocumented corner. Supposedly: * (TxTimer << 12) | (TxPackets << 8) | (RxTimer << 4) | RxPackets */ RTL_W16(IntrMitigate, 0x0000); https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/realtek/r8169.c#n6346 static void rtl_hw_start_8168(struct net_device *dev) { ... RTL_W16(IntrMitigate, 0x5151); and then I've also found https://www.spinics.net/lists/netdev/msg217665.html and original Francois' patch: https://www.spinics.net/lists/netdev/msg217984.html https://www.spinics.net/lists/netdev/msg218207.html So could we please finally get support for tuning r8169 interrupt coalescing in tree? (so that next poor soul who hits the problem does not need to go all the way to dig into driver sources and internet wildly and finally patch locally -RTL_W16(IntrMitigate, 0x5151); +RTL_W16(IntrMitigate, 0x5100); guessing whether it is right or not and also having to care to deploy the patch everywhere it needs to be used, etc...). To do so I've took original Francois's patch from 2012 and reworked it a bit: - updated to latest net-next.git; - adjusted scaling setup based on feedback from Hayes to pick up scaling vector depending not only on link speed but also on CPlusCmd[0:1] and to adjust CPlusCmd[0:1] correspondingly when setting timings; - improved a bit (I think so) error handling. I've tested the patch on "RTL8168d/8111d" (XID 083000c0) and with it and `ethtool -C rx-usecs 0 rx-frames 0` on both ends it improves: - minimum RTT latency: ~270μs -> ~30μs (small packet), ~330μs -> ~110μs (full 1.5K ethernet frame) - average RTT latency: ~480μs -> ~50μs (small packet), ~560μs -> ~125μs (full 1.5K ethernet frame) ( before: root@neo1:# ping -i 0 -w 3 -s 82 -q neo2 PING neo2.kirr.nexedi.com (192.168.102.21) 82(110) bytes of data. --- neo2.kirr.nexedi.com ping statistics --- 5906 packets transmitted, 5905 received, 0% packet loss, time 2999ms rtt min/avg/max/mdev = 0.274/0.485/0.607/0.026 ms, ipg/ewma 0.508/0.489 ms root@neo1:# ping -i 0 -w 3 -s 1472 -q neo2 PING neo2.kirr.nexedi.com (192.168.102.21) 1472(1500) bytes of data. --- neo2.kirr.nexedi.com ping statistics --- 5073 packets transmitted, 5073 received, 0% packet loss, time 2999ms rtt min/avg/max/mdev = 0.330/0.566/0.710/0.028 ms, ipg/ewma 0.591/0.544 ms after: root@neo1# ping -i 0 -w 3 -s 82 -q neo2 PING neo2.kirr.nexedi.com (192.168.102.21) 82(110) bytes of data. --- neo2.kirr.nexedi.com ping statistics --- 45815 packets transmitted, 45815 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.036/0.051/0.368/0.010 ms, ipg/ewma 0.065/0.053 ms root@neo1:# ping -i 0 -w 3 -s 1472 -q neo2 PING neo2.kirr.nexedi.com (192.168.102.21) 1472(1500) bytes of data. --- neo2.kirr.nexedi.com ping statistics --- 21250 packets transmitted, 21250 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.112/0.125/0.390/0.007 ms, ipg/ewma 0.141/0.125 ms the small -> 1.5K latency growth is understandable as it takes ~15μs to transmit 1.5K on 1Gbps on the wire and with 2 hosts and 1 switch and ICMP ECHO + ECHO reply the packet has to travel 4 ethernet segments which is already 60μs; probably something a bit else is also there as e.g. on Linux, even with `cpupower frequency-set -g performance`, on some computers I've noticed the kernel can be spending more time in software-only mode when incoming packets go in less frequently. E.g. this program can demonstrate the effect for ICMP ECHO processing: https://lab.nexedi.com/kirr/bcc/blob/43cfc13b/tools/pinglat.py (later this was found to be partly due to C-states exit latencies) ) We have this patch running in our testing setup for 1 months already without any issues observed. It remains to be clarified whether RX and TX timers use the same base. For now I've set them equally, but Francois's original patch version suggests it could be not the same. I've got no feedback at all to my original posting of this patch and questions https://www.spinics.net/lists/netdev/msg457173.html neither from Francois, nor from any people from Realtek during one month. So I suggest we simply apply it to net-next.git now.

IPvlan has always operated in bridge mode. However there are scenarios where each slave should be able to talk through the master device but not necessarily across each other. Think of an environment where each of a namespace is a private and independant customer. In this scenario the machine which is hosting these namespaces neither want to tell who their neighbor is nor the individual namespaces care to talk to neighbor on short-circuited network path. This patch implements the mode that is very similar to the 'private' mode in macvlan where individual slaves can send and receive traffic through the master device, just that they can not talk among slave devices.

Commit dec2c92880cc5435381d50e3045ef018a762a917 ("Bluetooth: hci_ldisc: Use rwlocking to avoid closing proto races") introduced locks in hci_ldisc that are held while calling the proto functions. These locks are rwlock's, and hence do not allow sleeping while they are held. However, the proto functions that hci_bcm registers use mutexes and hence need to be able to sleep. In more detail: hci_uart_tty_receive() and hci_uart_dequeue() both acquire the rwlock, after which they call proto->recv() and proto->dequeue(), respectively. In the case of hci_bcm these point to bcm_recv() and bcm_dequeue(). The latter both acquire the bcm_device_lock, which is a mutex, so doing so results in a call to might_sleep(). But since we're holding a rwlock in hci_ldisc, that results in the following BUG (this for the dequeue case - a similar one for the receive case is omitted for brevity): BUG: sleeping function called from invalid context at kernel/locking/mutex.c in_atomic(): 1, irqs_disabled(): 0, pid: 7303, name: kworker/7:3 INFO: lockdep is turned off.

Therefore this replaces the rwlock's in hci_ldisc with rw_semaphore's (which allow sleeping). This is a safer approach anyway as it reduces the restrictions on the proto callbacks. Also, because acquiring write-lock is very rare compared to acquiring the read-lock, the percpu variant of rw_semaphore is used. Lastly, because hci_uart_tx_wakeup() may be called from an IRQ context, we can't block (sleep) while trying acquire the read lock there, so we use the trylock variant.

Then the second interface will not have a chance to recover even if subsequent reclaims succeed. Possible solution is to attempt to wake all the s/w queues belonging to driver interfaces.

The patch implements functions and admin queue commands needed to support cloud filters in the driver and adds cloud filters to configure these tc-flower filters. The classification function of the filter is to direct matched packets to a traffic class. The hardware traffic class is set based on the the classid reserved in the range :ffe0 - :ffef.

Unsupported matches when cloud filters are added using enhanced big buffer cloud filter mode of underlying switch include: 1. source port and source IP 2. Combined MAC address and IP fields. 3. Not specifying L4 port These filter matches can however be used to redirect traffic to the main VSI (tc 0) which does not require the enhanced big buffer cloud filter support.

The problem with the current implementation is that there is no clear API to create a new group of stats. This change define a new API to create a group of stats and simplifies the way of handling them by defining a new struct "mlx5e_stats_grp" which have the following three function pointers: - get_num_stats() - return the number of counters in the group. - fill_strings() - fill counters strings within the group. - fill_stats() - fill counters values within the group. The above function pointers are used within the ethtool callbaks while calling "ethtool -S" from userspace. This change also switch the SW group to use the new API.

Time to reduce the memory consumption. Before: sizeof(struct bpf_verifier_state) = 6520 After: sizeof(struct bpf_verifier_state) = 896 It's done by observing that majority of BPF programs use little to no stack whereas verifier kept all of 512 stack slots ready always. Instead dynamically reallocate struct verifier state when stack access is detected. Runtime difference before vs after is within a noise. The number of processed instructions stays the same.

Note that FIB entries are no longer being offloaded to this device. This patch reworks FIB rule handling to return a message to the user: $ ip ru add pref 99 from all to 8.8.8.8 table 11 Error: spectrum: FIB rules not supported. Aborting offload. spectrum currently only checks whether the fib rule is a default rule or an l3mdev rule, both of which it knows how to handle. Any other it aborts FIB offload. Move the processing to check the rule type inline with the user request. If the rule is an unsupported one, then a work queue entry is used to abort the offload. Change the rule delete handling to just return since it does nothing at the moment. Signed-off-by: David Ahern Reviewed-by: Ido Schimmel Signed-off-by: David S.

Allocate SMT/L2T entries if DMAC-rewrite/SMAC-rewrite is requested. Allocate CLIP entry in case of IPv6 filter. Use cpl_act_open_req[6] to send hash filter create request to hw. Also, the filter tuple is calculated as part of sending this request. Hash-filter reply is processed on getting cpl_act_open_rpl. In case of success, various bits/fields in filter-tcb are set per filter requirement, such as enabling filter hitcnts, and/or various header rewrite operations, such as VLAN-rewrite, NAT or (L3/L4)-rewrite, and SMAC/DMAC-rewrite. In case of failure, clear the filter entry and release any hw resources occupied by it. The patch also moves the functions set_tcb_field, set_tcb_tflag and configure_filter_smac towards beginning of file.

This patch aligns the hardware's multipath parameters with the kernel's. For IPv4 packets, the parameters are determined according to the 'fib_multipath_hash_policy' sysctl during module initialization. In case L3-mode is requested, only the source and destination IP addresses are used. There is no special handling of ICMP error packets. In case L4-mode is requested, a 5-tuple is used: source and destination IP addresses, source and destination ports and IP protocol. Note that the layer 4 fields are not considered for fragmented packets. For IPv6 packets, the source and destination IP addresses are used, as well as the flow label and the next header fields.

This happens since NSSN is behind for a while, and the driver won't release the frames, since it is not allowed by NSSN. As a result the frame is stored in the reorder buffer although there is no hole, and released 100 ms later. Add a direct comparison to the reorder buffer head, and release immediately if possible. For example: Frame 0 is missed. We receive frame 1, and store it in the buffer. After 100 ms, frame 1 is released and reorder buffer head is 2. We then receive frame 2, with NSSN 0, and store it instead of releasing it.

It is currently only accessible within trans.c. Add it to struct iwl_trans_ops, so that failure cases in other files can call it. While there, add a call to this function from iwl_pcie_load_firmware_chunk in pcie/tx.c, since this is a common failure case seen on some platforms.

It will do so by storing struct ip_tunnel_parm with previous configuration, and comparing that to the new version. To facilitate these comparisons, extract the code that operates on struct ip_tunnel_parm from the existing accessor functions, and make those a thin wrapper that extracts tunnel parameters and dispatches.

So far, for creation of loopback interfaces, NULL was passed. For some events however the extack can be extracted and passed along. So do that for NETDEV_CHANGEUPPER handler. Use the opportunity to update the type of info argument that mlxsw_sp_netdevice_ipip_ol_event() takes. Follow-up patches will introduce handling of more changes, and some of them carry an extack as well, but in an info structure of a different type. Though not strictly erroneous (the pointer could be cast whichever way), it makes no sense to pretend the value is always of a certain type, when in fact it isn't.

This is currently immaterial, because only one tunnel type is offloaded, and therefore the UL protocol always matches, but introducing support for a tunnel with IPv6 underlay would uncover this error.

Previously, offloads were introduced on demand as encap routes were formed. When such a route was created that would cause offload of a conflicting tunnel, mlxsw_sp_ipip_entry_create() would detect it and return -EEXIST, which would propagate up and cause FIB abort. Now however IPIP entries are created as soon as an offloadable netdevice is created, and the failure prevents creation of such device. Furthermore, if the driver is installed at the point where such conflicting tunnels exist, the failure actually prevents successful modprobe. Furthermore, follow-up patches implement handling of NETDEV_CHANGE due to the local address change. However, NETDEV_CHANGE can't be vetoed. The failure merely means that the offloads weren't updated, but the change in Linux configuration is not rolled back. It is thus desirable to have a robust way of handling these conflicts, which can later be reused for handling NETDEV_CHANGE as well. To fix this, when a conflicting tunnel is created, instead of failing, simply pull the old tunnel to slow path and reject offloading the new one. Introduce two functions: mlxsw_sp_ipip_entry_demote_tunnel() and mlxsw_sp_ipip_demote_tunnel_by_saddr() to handle this. Make them both public, because they will be useful later on in this patchset.

Extend mlxsw_sp_nexthop_rif_update() to take IFF_UP into consideration when deciding whether a given next hop should be offloaded. Because the new logic was added to mlxsw_sp_nexthop_rif_update(), this fixes the case where a newly-added tunnel has a down bound device, which would previously be fully offloaded. Now the down state of the bound device is noted and next hops forwarding to such tunnel are not offloaded. In addition to that, notice NETDEV_UP and NETDEV_DOWN of a bound device to force refresh of tunnel encap route offloads.

Device maintains internal trust state which needs to be set to DSCP state for performing DSCP to priority mapping. When the first dscp to priority APP entry is added by the user, the trust state is changed to dscp. When the last dscp to priority APP entry is deleted by the user, the trust state is changed to pcp. If user sends multiple dscp to priority APP entries on the same dscp, the last sent one will take effect. All the previous sent will be deleted. The dscp to priority APP entries are added and deleted in the net/dcb APP database using dcb_ieee_setapp/getapp. Signed-off-by: Huy Nguyen Reviewed-by: Parav Pandit Reviewed-by: Or Gerlitz Signed-off-by: Saeed Mahameed --- drivers/net/ethernet/mellanox/mlx5/core/en.h | 15 +- drivers/net/ethernet/mellanox/mlx5/core/en_dcbnl.c | 204 +++++++++++++++++++++ drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 15 +- 3 files changed, 232 insertions(+), 2 deletions(-) (limited to 'drivers') diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en.h b/drivers/net/ethernet/mellanox/mlx5/core/en.h index e613ce02216d..ab6f0c18850f 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/en.h +++ b/drivers/net/ethernet/mellanox/mlx5/core/en.h @@ -57,6 +57,7 @@ #define MLX5E_HW2SW_MTU(priv, hwmtu) ((hwmtu) - ((priv)->hard_mtu)) #define MLX5E_SW2HW_MTU(priv, swmtu) ((swmtu) + ((priv)->hard_mtu)) +#define MLX5E_MAX_DSCP 64 #define MLX5E_MAX_NUM_TC 8 #define MLX5E_PARAMS_MINIMUM_LOG_SQ_SIZE 0x6 @@ -260,11 +261,17 @@ enum { struct mlx5e_dcbx { enum mlx5_dcbx_oper_mode mode;

This is done by selecting the transmit queue based on the dscp of the skb. Until now select_queue honors priority only from the vlan header. However that is not sufficient in cases where port trust state is DSCP mode as packet might not even contain vlan header. Therefore if the port is in dscp trust state and vport's min inline mode is not NONE, copy the IP header to the eseg's inline header if the skb has it. This is done by changing the transmit queue sq's min inline mode to L3. Note that the min inline mode of sqs that belong to other features such as xdpsq, icosq are not modified.

Change it to be min(max NIC RX table size, min(max flow counters, 64k) * num flow groups) where the max values are read from the firmware and the number of flow groups is hard-coded as before this change. We don't know upfront the division of flows to groups (== different masks). This setup allows each group to be of size up to the where we want to go (when supported, all offloaded flows use counters). Thus, we don't expect multiple occurences for a group which in turn would add steering hops.

Besides the benefit of less interrupts, this also allows the kernel to better utilize TSO. Since TSO has some CPU overhead, it might not aggregate when CPU is under high stress. By reducing the interrupt rate and the CPU utilization, we can get better aggregation and better overall throughput. The feature is enabled by default and has a private flag in ethtool for control.

This simplifies preparing the offload since there will now be only one mode of operation for that type of program. We need to know the attachment mode type of cls_bpf programs, because exit codes are interpreted differently for legacy vs DA mode.

Take advantage of the new infrastructure. Allocation of driver metadata has to be moved from jit.c to offload.c since it's now done at a different stage. Since there is no separate driver private data for verification step, move temporary nfp_meta pointer into nfp_prog. We will now use user space context offsets.

The forced inlining does the trick for gcc, but for kernel builds with clang it results in undefined symbols: drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.o: In function `__nfp_eth_set_aneg': drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x787): undefined reference to `__compiletime_assert_492' drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x7b1): undefined reference to `__compiletime_assert_496' These __compiletime_assert_xyx() calls would have been optimized away if the compiler had seen 'mask' as a constant.

When loading the driver check if there are changes pending and if so call NSP MAC reinit. Full application FW reload is still required, and all MACs need to be reinited at the same time (not only the ones which have been reconfigured, and thus potentially causing disruption to unrelated netdevs) therefore for now changing MAC config without reloading the driver still remains future work.

This check is not needed since the only use case that could exercise this at the moment, would be to modify the number of SRIOV VFs without first disabling them. This case is explicitly disallowed in any case and subsequent patches in this series need to be able to replace the running set of reprs. All cases where the return code used to be checked for the nfp_app_reprs_set function have been removed. As stated above, it is not possible for the current code to encounter a case where reprs exist and need to be replaced.

Instead of using CHECKSUM_COMPLETE offload for packets with first ethertype of IPv4/6, use it for packets with last ethertype of IPv4/6 to cover the former cases as well. The checksum field present in the CQE is calculated from the IP header until the end of the packet. When the first ethertype is different than IPv4/6 (for ex. 802.1Q VLAN) a checksum of the VLAN header/s should be added. The small header/s checksum calculation will allow us to use CHECKSUM_COMPLETE instead of CHECKSUM_UNNECESSARY.

Furthermore, driver better not assume any capabilities and just use whetever is reported by device itself. To support this, convert "get channels" command into "get band info" command. Difference is that it may also carry HT/VHT capabilities along with channels information. While at it, also add "num_bitrates" field to "get band info" command, for future use.

Mark device not present when we encounter this error similar like we do with ENODEV error. Otherwise we can have infinite loop in rt2x00usb_work_rxdone(), because we remove and put again RX entries to the queue infinitely. We can have similar situation when submit urb will fail all the time with other error, so we need consider to limit number of entries processed by rxdone work. But for now, since the patch fixes reproducible soft lockup issue on single processor systems and taken ENOENT error meaning, let apply this fix. Patch adds additional ENOENT check not only in rx kick routine, but also on other places where we check for ENODEV error.

The timestamp is using an unsigned 32-bit value, so we could make it work until 2106 by using ktime_get_real_ts64(), but it seems better to use monotonic times, as we normally want for timestamps. Since this is an interface change, I'm incrementing the DUMP_HEADER_VERSION number, so user space can figure out whether the timestamps are monotonic or not. Most likely the tools won't care either way. Generally speaking, ABI version numbers and in particular changing them is a bad idea. However since this is in debugfs, we don't put any API stability rules on the interface according to Documentation/filesystems/debugfs.txt, and we can take the easy way out here; anyone using the frame dump feature can probably work out the differences here.

I moved the allocation to the probe() function and made it managed. >From the Colin's email: While running static analysis on linux-next with CoverityScan I found 3 double free errors in the Cavium thunder driver. The issue occurs on the err_disable_device: label of function nic_probe when nic_free_lmacmem(nic) is called and a double free occurs on nic->duplex, nic->link and nic->speed. This occurs when nic_init_hw() fails: /* Initialize hardware */ err = nic_init_hw(nic); if (err) goto err_release_regions; nic_init_hw() calls nic_get_hw_info() and this calls nic_free_lmacmem() if any of the allocations fail. This free'ing occurs again by the call to nic_free_lmacmem() on the err_release_regions exit path in nic_probe(). Reported-by: Colin Ian King Signed-off-by: Aleksey Makarov Signed-off-by: David S.

It loops the ports and checks to see if there are ports in a different bridge with the same VLAN. While walking all switch ports, the code was checking if the new port has a netdev slave attached to it. If not, skip checking the port being walked. This seems like a typ0. If the new port does not have a slave, how has a VLAN been added to it in the first place, requiring this check be performed at all? More likely, we should be checking if the port being walked has a slave. Without the port having a slave, it cannot have a VLAN on it, so there is no need to check further for that particular port.

Instead the broadcast address is unknown in the ATU, so the frame gets forwarded out the cpu port. The software bridge then floods it back to the individual switch ports which are members of the bridge. Add an ATU entry in the switch so that it floods broadcast frames out ports, rather than have the software bridge do it. Also, send a copy out the cpu port and any dsa ports. Rely on the port vectors to prevent broadcast frames leaking between bridges, and separated ports. Additionally, when a VLAN is added, a new FID is allocated. This represents a new table of ATU entries. A broadcast entry is added to the new FID. With offload_fwd_mark being set, the software bridge will not flood the frames it receives back to the switch.

The message "bnx2x: [bnx2x_alloc_mem:8399(em4)]Can't allocate memory" pops out. The variable slowpath is set to NULL. When shutdown the NIC, the function bnx2x_nic_unload is called.

It turned out that no interrupts were triggered. Further analysis showed the register INER can't be altered on page 0. Because register INSR needs to be accessed via page 0xa43 I assumed that register INER needs to be accessed via some page too. Some brute force check resulted in page 0xa42 being the right one.

Then, a maximum of 255 Tx descriptors can be added at once. In the current code the mvneta_txq_pend_desc_add function assumes the caller takes care of this limit. But it is not the case. In some situations (xmit_more flag), more than 255 descriptors are added. When this happens, the Tx descriptor counter register is updated with a wrong value, which breaks the whole Tx queue management. This patch fixes the issue by allowing the mvneta_txq_pend_desc_add function to process more than 255 Tx descriptors.

However, priv->tx_path_in_lpi_mode is assigned using the return value from host_irq_status(). So for dwmac4, priv->tx_path_in_lpi_mode was always false, so stmmac_tx_clean() would always try to put us in eee mode, and stmmac_xmit() would never take us out of eee mode. To fix this, make host_irq_status() read and return the LPI irq status also for dwmac4. This also increments the existing LPI counters, so that ethtool --statistics shows LPI transitions also for dwmac4. For dwmac1000, irqs are enabled/disabled using the register named "Interrupt Mask Register", and thus setting a bit disables that specific irq. For dwmac4 the matching register is named "MAC_Interrupt_Enable", and thus setting a bit enables that specific irq. Looking at dwmac1000_core.c, the irqs that are always enabled are: LPI and PMT. Looking at dwmac4_core.c, the irqs that are always enabled are: PMT. To be able to read the LPI irq status, we need to enable the LPI irq also for dwmac4.

Establishing trust requires the user to confirm a dialog on the iOS device.Until trust is established, the iOS device will silently discard network packets from the host. Currently, the ipheth driver does not detect whether an iOS device has established trust with the host, and immediately sets up the transmit queues. This causes the following problems: - Kernel taint due to WARN() in netdev watchdog. - Dmesg spam ("TX timeout"). - Disruption of user space networking activity (dhcpd, etc...) when new interface comes up but cannot be used. - Unnecessary host and device wakeups and USB traffic Example dmesg output: [ 1101.319778] NETDEV WATCHDOG: eth1 (ipheth): transmit queue 0 timed out [ 1101.319817] ------------[ cut here ]------------ [ 1101.319828] WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:316 dev_watchdog+0x20f/0x220 [ 1101.319831] Modules linked in: ipheth usbmon nvidia_drm(PO) nvidia_modeset(PO) nvidia(PO) iwlmvm mac80211 iwlwifi btusb btrtl btbcm btintel qmi_wwan bluetooth cfg80211 ecdh_generic thinkpad_acpi rfkill [last unloaded: ipheth] [ 1101.319861] CPU: 0 PID: 0 Comm: swapper/0 Tainted: P O 4.13.12.1 #1 [ 1101.319864] Hardware name: LENOVO 20ENCTO1WW/20ENCTO1WW, BIOS N1EET62W (1.35 ) 11/10/2016 [ 1101.319867] task: ffffffff81e11500 task.stack: ffffffff81e00000 [ 1101.319873] RIP: 0010:dev_watchdog+0x20f/0x220 [ 1101.319876] RSP: 0018:ffff8810a3c03e98 EFLAGS: 00010292 [ 1101.319880] RAX: 000000000000003a RBX: 0000000000000000 RCX: 0000000000000000 [ 1101.319883] RDX: ffff8810a3c15c48 RSI: ffffffff81ccbfc2 RDI: 00000000ffffffff [ 1101.319886] RBP: ffff880c04ebc41c R08: 0000000000000000 R09: 0000000000000379 [ 1101.319889] R10: 00000100696589d0 R11: 0000000000000378 R12: ffff880c04ebc000 [ 1101.319892] R13: 0000000000000000 R14: 0000000000000001 R15: ffff880c2865fc80 [ 1101.319896] FS: 0000000000000000(0000) GS:ffff8810a3c00000(0000) knlGS:0000000000000000 [ 1101.319899] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1101.319902] CR2: 00007f3ff24ac000 CR3: 0000000001e0a000 CR4: 00000000003406f0 [ 1101.319905] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 1101.319908] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 1101.319910] Call Trace: [ 1101.319914] [ 1101.319921] ? dev_graft_qdisc+0x70/0x70 [ 1101.319928] ? dev_graft_qdisc+0x70/0x70 [ 1101.319934] ? call_timer_fn+0x2e/0x170 [ 1101.319939] ? dev_graft_qdisc+0x70/0x70 [ 1101.319944] ? run_timer_softirq+0x1ea/0x440 [ 1101.319951] ? timerqueue_add+0x54/0x80 [ 1101.319956] ? enqueue_hrtimer+0x38/0xa0 [ 1101.319963] ? __do_softirq+0xed/0x2e7 [ 1101.319970] ? irq_exit+0xb4/0xc0 [ 1101.319976] ? smp_apic_timer_interrupt+0x39/0x50 [ 1101.319981] ? apic_timer_interrupt+0x8c/0xa0 [ 1101.319983] [ 1101.319992] ? cpuidle_enter_state+0xfa/0x2a0 [ 1101.319999] ? do_idle+0x1a3/0x1f0 [ 1101.320004] ? cpu_startup_entry+0x5f/0x70 [ 1101.320011] ? start_kernel+0x444/0x44c [ 1101.320017] ? early_idt_handler_array+0x120/0x120 [ 1101.320023] ? x86_64_start_kernel+0x145/0x154 [ 1101.320028] ? secondary_startup_64+0x9f/0x9f [ 1101.320033] Code: 20 04 00 00 eb 9f 4c 89 e7 c6 05 59 44 71 00 01 e8 a7 df fd ff 89 d9 4c 89 e6 48 c7 c7 70 b7 cd 81 48 89 c2 31 c0 e8 97 64 90 ff <0f> ff eb bf 66 66 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 [ 1101.320103] ---[ end trace 0cc4d251e2b57080 ]--- [ 1101.320110] ipheth 1-5:4.2: ipheth_tx_timeout: TX timeout The last message "TX timeout" is repeated every 5 seconds until trust is established or the device is disconnected, filling up dmesg. The proposed patch eliminates the problem by, upon connection, keeping the TX queue and carrier disabled until a packet is first received from the iOS device. This is reflected by the confirmed_pairing variable in the device structure. Only after at least one packet has been received from the iOS device, the transmit queue and carrier are brought up during the periodic device poll in ipheth_carrier_set. Because the iOS device will always send a packet immediately upon trust being established, this should not delay the interface becoming useable. To prevent failed UBRs in ipheth_rcvbulk_callback from perpetually re-enabling the queue if it was disabled, a new check is added so only successful transfers re-enable the queue, whereas failed transfers only trigger an immediate poll. This has the added benefit of removing the periodic control requests to the iOS device until trust has been established and thus should reduce wakeup events on both the host and the iOS device.
