This is a test to verify that bpf: fix states equal logic for varlen access actually fixed the problem. The problem was if the register we added to our map register was UNKNOWN in both the false and true branches and the only thing that changed was the range then we'd incorrectly assume that the true branch was valid, which it really wasnt. This tests this case and properly fails without my fix in place and passes with it in place.

The cpdma has 8 rate limited tx channels. This patch adds ability for cpdma driver to use 8 tx h/w shapers. If at least one channel is not rate limited then it must have higher number, this is because the rate limited channels have to have higher priority then not rate limited channels. The channel priority is set in low-hi direction already, so that when a new channel is added with ethtool and it doesn't have rate yet, it cannot affect on rate limited channels. It can be useful for TSN streams and just in cases when h/w rate limited channels are needed. Signed-off-by: NIvan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: NDavid S.

Yuval Mintz says: ==================== qed*: Add XDP support This patch series is intended to add XDP to the qede driver, although it contains quite a bit of cleanups, refactorings and infrastructure changes as well. The content of this series can be roughly divided into: - Datapath improvements - mostly focused on having the datapath utilize parameters which can be more tightly contained in cachelines. Patches #1, #2, #8, #9 belong to this group. - Refactoring - done mostly in favour of XDP. Patches #3, #4, #5, #9. - Infrastructure changes - done in favour of XDP.

Add support for forwarding via XDP. Once the eBPF is attached, driver would allocate & configure a designated transmission queue meant solely for forwarding packets. Said queue would share the receive-queue's interrupt line, and would have it's own Tx statistics. Infrastructure changes required for this [spread-out through the code]: - Determine the DMA direction of the receive buffers based on the presence of the eBPF program. - Turn the sw Tx ring into a union, as regular/XDP queues have different needs for releasing resources after completion [regular requires the SKB, XDP requires the transmitted page].

Improve the cacheline usage of both queues by reordering - This reduces the cachelines required for egress datapath processing from 3 to 2 and those required by ingress datapath processing by 2. It also changes a couple of datapath related functions that currently require either the fastpath or the qede_dev, changing them to be based on the tx/rx queue instead.

The driver needs to maintain several FW/HW-indices for each one of its queues. Currently, that mapping is done by the QED where it uses an rx/tx array of so-called hw-cids, populating them whenever a new queue is opened and clearing them upon destruction of said queues. This maintenance is far from ideal - there's no real reason why QED needs to maintain such a data-structure. It becomes even worse when considering the fact that the PF's queues and its child VFs' queues are all mapped into the same data-structure. As a by-product, the set of parameters an interface needs to supply for queue APIs is non-trivial, and some of the variables in the API structures have different meaning depending on their exact place in the configuration flow. This patch re-organizes the way L2 queues are configured and maintained. In short: - Required parameters for queue init are now well-defined. - Qed would allocate a queue-cid based on parameters. Upon initialization success, it would return a handle to caller. - Queue-handle would be maintained by entity requesting queue-init, not necessarily qed. - All further queue-APIs [update, destroy] would use the opaque handle as reference for the queue instead of various indices. The possible owners of such handles: - PF queues [qede] - complete handles based on provided configuration. - VF queues [qede] - fw-context-less handles, containing only relative information; Only the PF-side would need the absolute indices for configuration, so they're omitted here. - VF queues [qed, PF-side] - complete handles based on VF initialization.

As qede utilizes an internal-reload sequence as result of various configuration changes, the netif state wouldn't always accurately describe the status of the configuration. To compensate, we're storing an internal state of the device, which should only be accessed under the qede_lock. This patch fixes and improves several state/lock interactions: - The internal state should only be checked while locked. - While holding lock, it's preferable to check state rather than the netdevice's state. - The reload sequence is not 'atomic' - unload and subsequent load are not in the same critical section. This also add the 'locked' variant for the reload, which would later be used by XDP - useful in the case where the correct sequence is 'lock, check state and re-configure if good', instead of allowing the reload itself to make the decision regarding the configurability of the device.

Driver's NAPI poll is using a long sequence for processing ingress packets, and it's going to get even longer once we do XDP. Break down the main loop into a series of sub-functions to allow better readability of the function. While we're at it, correct the accounting of the NAPI budget - currently we're counting only packets passed to the stack against the budget, even in case those are actually aggregations. After refactoring every CQE processed would be counted against the budget. Signed-off-by: NYuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The chain structure and functions are widely used by the qed* modules, both for configuration and datapath. E.g., qede's Tx has one such chain and its Rx has two. Currently, the strucutre's fields which are required for datapath related functions [produce/consume] are intertwined with fields which are required only for configuration purposes [init/destroy/etc.]. This patch re-arranges the chain structure so that all the fields which are required for datapath usage could reside in a single cacheline instead of the two which are required today.

Driver needs to maintain a structure per-each concurrent possible open aggregation, but the structure storing that metadata is far from being optimized - biggest waste in it is that there are 2 buffer metadata, one for a replacement buffer when the aggregation begins and the other for holding the first aggregation's buffer after it begins [as firmware might still update it]. Those 2 can safely be united into a single metadata structure. struct qede_agg_info changes the following: /* size: 120, cachelines: 2, members: 9 */ /* sum members: 114, holes: 1, sum holes: 4 */ /* padding: 2 */ /* paddings: 2, sum paddings: 8 */ /* last cacheline: 56 bytes */ --> /* size: 48, cachelines: 1, members: 9 */ /* paddings: 1, sum paddings: 4 */ /* last cacheline: 48 bytes */ Signed-off-by: NYuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: NDavid S.

Currently loop index 'idx' is used as the index in the neigh list of interest. It's increased only when the neigh is dumped. It's not the absolute index in the list. Because there is no info to record which neigh has already be scanned by previous loop. This will cause the filtered out neighs to be scanned mulitple times. This patch make idx as the absolute index in the list, it will increase no matter whether the neigh is filtered. This will prevent the above problem.

This patch modifies test_cgrp2_attach to use getopt so we can use standard command line parsing. It also adds an option to run the program in detach only mode. This does not attach a new filter at the cgroup, but only runs the detach command. Lastly, it changes the attach code to not detach and then attach. It relies on the 'hotswap' behaviour of CGroup BPF programs to be able to change in-place. If detach-then-attach behaviour needs to be tested, the example can be run in detach only mode prior to attachment.

When passed XDP_FLAGS_UPDATE_IF_NOEXIST, we can handle this more graceful when requested by returning -EBUSY in case we try to attach a new program, but we find that another one is already attached.
