If CONFIG_AF_RXRPC_DEBUG_RX_DELAY=y, then a delay is injected between packets and errors being received and them being made available to the processing code, thereby allowing the RTT to be artificially increased.

Jiri Pirko authored
Devlink features were introduced to disallow devlink reload calls of userspace before the devlink was fully initialized. The reason for this workaround was the fact that devlink reload was originally called without devlink instance lock held. However, with recent changes that converted devlink reload to be performed under devlink instance lock, this is redundant so remove devlink features entirely. Note that mlx5 used this to enable devlink reload conditionally only when device didn't act as multi port slave. Move the multi port check into mlx5_devlink_reload_down() callback alongside with the other checks preventing the device from reload in certain states.

Currently, the notifications are only sent for params. People who introduced other objects forgot to add the reload notifications here. To make sure all notifications happen according to existing comment, benefit from existence of devlink_notify_register/unregister() helpers and use them in reload code.

This effectively reverts commit 05a7f4a8 ("devlink: Break parameter notification sequence to be before/after unload/load driver"). Cited commit resolved a problem in mlx5 params implementation, when param notification code accessed memory previously freed during reload. Now, when the params can be registered and unregistered when devlink instance is registered, mlx5 code unregisters the problematic param during devlink reload. The fix is therefore no longer needed. Current behavior is a it problematic, as it sends DEL notifications even in potential case when reload_down() call fails which might confuse userspace notifications listener. So move the reload notifications back where they were originally in between reload_down() and reload_up() calls.

Steen Hegelund says: ==================== Adding Sparx5 ES2 VCAP support This provides the Egress Stage 2 (ES2) VCAP (Versatile Content-Aware Processor) support for the Sparx5 platform. The ES2 VCAP is an Egress Access Control VCAP that uses frame keyfields and previously classified keyfields to apply e.g. policing, trapping or mirroring to frames. The ES2 VCAP has 2 lookups and they are accessible with a TC chain id: - chain 20000000: ES2 Lookup 0 - chain 20100000: ES2 Lookup 1 As the other Sparx5 VCAPs the ES2 VCAP has its own lookup/port keyset configuration that decides which keys will be used for matching on which traffic type. The ES2 VCAP has these traffic classifications: - IPv4 frames - IPv6 frames - Other frames The ES2 VCAP can match on an ISDX key (Ingress Service Index) as one of the frame metadata keyfields. The IS0 VCAP can update this key using its actions, and this allows a IS0 VCAP rule to be linked to an ES2 rule. This is similar to how the IS0 VCAP and the IS2 VCAP use the PAG (Policy Association Group) keyfield to link rules. From user space this is exposed via "chain offsets", so an IS0 rule with a "goto chain 20000015" action will use an ISDX key value of 15 to link to a rule in the ES2 VCAP attached to the same chain id. ==================== Signed-off-by: David S.

This ensures that it will be possible for a VCAP rule to distinguish IPv6 frames from non-IP frames, as the IS0 keyset usually selected for the IPv6 traffic class in (7TUPLE) does not offer a key that specifies IPv6 directly: only non-IPv4.

This patch removes the msleep(4s) during netpoll_setup() if the carrier appears instantly. Here are some scenarios where this workaround is counter-productive in modern ages: Servers which have BMC communicating over NC-SI via the same NIC as gets used for netconsole. BMC will keep the PHY up, hence the carrier appearing instantly. The link is fibre, SERDES getting sync could happen within 0.1Hz, and the carrier also appears instantly. Other than that, if a driver is reporting instant carrier and then losing it, this is probably a driver bug.

This is important for two reasons. First, a redirect to an XSKMAP assumes that a call to xdp_do_redirect() from napi context X on CPU Y will be followed by a xdp_do_flush() from the same napi context and CPU. This is not guaranteed if the napi_complete_done() is executed before xdp_do_flush(), as it tells the napi logic that it is fine to schedule napi context X on another CPU. Details from a production system triggering this bug using the veth driver can be found in [1]. The second reason is that the XDP_REDIRECT logic in itself relies on being inside a single NAPI instance through to the xdp_do_flush() call for RCU protection of all in-kernel data structures. Details can be found in [2]. The drivers have only been compile-tested since I do not own any of the HW below. So if you are a maintainer, it would be great if you could take a quick look to make sure I did not mess something up. Note that these were the drivers I found that violated the ordering by running a simple script and manually checking the ones that came up as potential offenders. But the script was not perfect in any way. There might still be offenders out there, since the script can generate false negatives.

This fixes the doxygen format documentation above the user_ring_buffer__* APIs. There has to be a newline before the @brief, otherwise doxygen won't render them for libbpf.readthedocs.org.

Jiri Pirko says: ==================== devlink: Cleanup params usage This patchset takes care of small cleanup of devlink params usage. Some of the patches (first 2/3) are cosmetic, but I would like to point couple of interesting ones: Patch 9 is the main one of this set and introduces devlink instance locking for params, similar to other devlink objects. That allows params to be registered/unregistered when devlink instance is registered. Patches 10-12 change mlx5 code to register non-driverinit params in the code they are related to, and thanks to patch 8 this might be when devlink instance is registered - for example during devlink reload. --- v1->v2: - Just small fix in the last patch ==================== Signed-off-by: David S.
