Indirection table is dumped as a raw u32 array, decode it. It's tempting to decode hash key, too, but it is an actual bitstream, so leave it be for now.

Applications may want to deal with dynamic RSS contexts only. So dumping context 0 will be counter-productive for them. Support starting the dump from a given context ID. Alternative would be to implement a dump flag to skip just context 0, not sure which is better...

Now that we track RSS contexts in the core we can easily dump them. This is a major introspection improvement, as previously the only way to find all contexts would be to try all ids (of which there may be 2^32 - 1). Don't use the XArray iterators (like xa_for_each_start()) as they do not move the index past the end of the array once done, which caused multiple bugs in Netlink dumps in the past.

marvell/otx2 and mvpp2 do not support setting different keys for different RSS contexts. Contexts have separate indirection tables but key is shared with all other contexts. This is likely fine, indirection table is the most important piece. Don't report the key-related parameters from such drivers. This prevents driver-errors, e.g. otx2 always writes the main key, even when user asks to change per-context key. The second reason is that without this change tracking the keys by the core gets complicated. Even if the driver correctly reject setting key with rss_context != 0, change of the main key would have to be reflected in the XArray for all additional contexts. Since the additional contexts don't have their own keys not including the attributes (in Netlink speak) seems intuitive. ethtool CLI seems to deal with it just fine. Having to set the flag in majority of the drivers is a bit tedious but not reporting the key is a safer default.

cap_rss_ctx_supported was created because the API for creating and configuring additional contexts is mux'ed with the normal RSS API. Presence of ops does not imply driver can actually support rss_context != 0 (in fact drivers mostly ignore that field). cap_rss_ctx_supported lets core check that the driver is context-aware before calling it. Now that we have .create_rxfh_context, there is no such ambiguity. We can depend on presence of the op. Make setting the bit optional.

Implement the separate create/modify/delete ops for RSS. No problems with IDs - even tho RSS tables are per device the driver already seems to allocate IDs linearly per port. There's a translation table from per-port context ID to device context ID. mvpp2 doesn't have a key for the hash, it defaults to an empty/previous indir table. Note that there is no key at all, so we don't have to be concerned with reporting the wrong one (which is addressed by a patch later in the series). Compile-tested only.

Russell King (Oracle) authored
We have an increasing number of drivers that are forcing auto-negotiation to be enabled for speeds of 1G or faster. It would appear that auto-negotiation is mandatory for speeds above 100M. In 802.3, Annex 40C's state diagrams seems to imply that mr_autoneg_enable (BMCR AN ENABLE) doesn't affect whether or not the AN state machines work for 1000base-T, and some PHY datasheets (e.g. Marvell Alaska) state that disabling mr_autoneg_enable leaves AN enabled but forced to 1G full duplex. Other PHY datasheets imply that BMCR AN ENABLE should not be cleared for >= 1G. Thus, this should be handled in phylib rather than in each driver. Rather than erroring out, arrange to implement the Marvell Alaska solution but in software for all PHYs: generate an appropriate single-speed advertisement for the requested speed, and keep AN enabled to the PHY driver. However, to avoid userspace API breakage, continue to report to userspace that we have AN disabled. Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: David S.

The iterated nodes are direct children of the device node, and the `device_for_each_child_node()` macro accounts for child node availability. `fwnode_for_each_available_child_node()` is meant to access the child nodes of an fwnode, and therefore not direct child nodes of the device node. The child nodes within mvpp2_probe are not accessed outside the loops, and the scoped version of the macro can be used to automatically decrement the refcount on early exits. Use `device_for_each_child_node()` and its scoped variant to indicate device's direct child nodes.

As discussed in [1], there is no need to iterate over child nodes to remove the list of ports. Instead, a loop up to `port_count` ports can be used, and is in fact more reliable in case the child node availability changes. The suggested approach removes the need for the `fwnode` and `port_fwnode` variables in mvpp2_remove() as well.

David Wei says: ==================== fix bnxt_en queue reset when queue is active The current bnxt_en queue API implementation is buggy when resetting a queue that has active traffic. The problem is that there is no FW involved to stop the flow of packets and relying on napi_disable() isn't enough. To fix this, call bnxt_hwrm_vnic_update() with MRU set to 0 for both the default and the ntuple vnic to stop the flow of packets. This works for any Rx queue and not only those that have ntuple rules since every Rx queue is either in the default or the ntuple vnic. For bnxt_hwrm_vnic_update() to work, proper flushing must be done by the FW. A FW flag is there to indicate support and queue_mgmt_ops is keyed behind this. The first three patches are from Michael Chan and adds the prerequisite vnic functions and FW flags indicating that it will properly flush during vnic update. Tested on BCM957504 while iperf3 is active: 1. Reset a queue that has an ntuple rule steering flow into it 2. Reset all queues in order, one at a time In both cases the flow is not interrupted. Sending this to net-next as there is no in-tree kernel consumer of queue API just yet, and there is a patch that changes when the queue_mgmt_ops is registered.

The queue API calls bnxt_hwrm_vnic_update() to stop/start the flow of packets, which can only properly flush the pipeline if FW indicates support.

David Wei authored
The current implementation when resetting a queue while packets are flowing puts the queue into an inconsistent state. There needs to be some synchronisation with the FW. Add calls to bnxt_hwrm_vnic_update() to set the MRU for both the default and ntuple vnic during queue start/stop. When the MRU is set to 0, flow is stopped. Each Rx queue belongs to either the default or the ntuple vnic. With calling bnxt_hwrm_vnic_update() the calls to napi_enable() and napi_disable() must be removed for reset to work on a queue that has active traffic flowing e.g. iperf3.

James Chapman authored
syzbot exposes a race where a net used by l2tp is removed while an existing pppol2tp socket is closed. In l2tp_pre_exit_net, l2tp queues TUNNEL_DELETE work items to close each tunnel in the net. When these are run, new SESSION_DELETE work items are queued to delete each session in the tunnel. This all happens in drain_workqueue. However, drain_workqueue allows only new work items if they are queued by other work items which are already in the queue. If pppol2tp_release runs after drain_workqueue has started, it may queue a SESSION_DELETE work item, which results in the warning below in drain_workqueue. Address this by flushing the workqueue before drain_workqueue such that all queued TUNNEL_DELETE work items run before drain_workqueue is started. This will queue SESSION_DELETE work items for each session in the tunnel, hence pppol2tp_release or other API requests won't queue SESSION_DELETE requests once drain_workqueue is started.

l2tp management APIs and procfs/debugfs iterate over l2tp tunnel and session lists. Since these lists are now implemented using IDR, we can use IDR get_next APIs to iterate them. Add tunnel/session get_next functions to do so. The session get_next functions get the next session in a given tunnel and need to account for l2tpv2 and l2tpv3 differences: * l2tpv2 sessions are keyed by tunnel ID / session ID. Iteration for a given tunnel ID, TID, can therefore start with a key given by TID/0 and finish when the next entry's tunnel ID is not TID. This is possible only because the tunnel ID part of the key is the upper 16 bits and the session ID part the lower 16 bits; when idr_next increments the key value, it therefore finds the next sessions of the current tunnel before those of the next tunnel. Entries with session ID 0 are always skipped because they are used internally by pppol2tp. * l2tpv3 sessions are keyed by session ID. Iteration starts at the first IDR entry and skips entries where the tunnel does not match. Iteration must also consider session ID collisions and walk the list of colliding sessions (if any) for one which matches the supplied tunnel.

Patches #3 and #4 by Jianbo add TC offload support for complicated rules to overcome firmware limitation. Patch #5 by Gal unifies the access macro to advertised/supported link modes. Patches #6 to #9 by Gal adds extack messages in ethtool ops to replace prints to the kernel log. Patch #10 by Cosmin switches to using 'update' verb instead of 'replace' to better reflect the operation. Patch #11 by Cosmin exposes an update connection tracking operation to replace the assumed delete+add implementaiton. ==================== Link: https://patch.msgid.link/20240808055927.2059700-1-tariqt@nvidia.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Previously, replacing a connection tracking steering entry was done by adding a new rule (with the same tag but possibly different mod hdr actions/labels) then removing the old rule. This approach doesn't work in hardware steering because two steering entries with the same tag cannot coexist in a hardware steering table. This commit prepares for that by adding a new ct_rule_update operation on the ct_fs_ops struct which is used instead of add+delete. Implementations for both dmfs (firmware steering) and smfs (software steering) are provided, which simply add the new rule and delete the old one.

Offloaded rules can be updated with a new modify header action containing a changed restore cookie. This was done using the verb 'replace', while in some configurations 'update' is a better fit. This commit renames the functions used to reflect that.
