Esben Haabendal says: ==================== net: gianfar: 64-bit statistics and rx_missed_errors counter This series replaces the legacy 32-bit statistics to proper 64-bit ditto, and implements rx_missed_errors counter on top of that. The device supports a 16-bit RDRP counter, and a related carry bit and interrupt, which allows implementation of a robust 64-bit counter. ==================== Signed-off-by:David S.

Devices with RMON support has a 16-bit RDRP counter. It provides: "Receive dropped packets counter. Increments for frames received which are streamed to system but are later dropped due to lack of system resources." To handle more than 2^16 dropped packets, a carry bit in CAR1 register is set on overflow, so we enable irq when this is set, extending the counter to 2^64 for handling situations where lots of packets are missed (e.g. during heavy network storms).

The memset on CAMx is wrong, as it actually unmasks all carry irq's, which we clearly are not interested in. The memset on CARx registers is just pointless, as they are W1C. So let's just stop the memset before CAR1. Signed-off-by:

The CAR1 and CAR2 registers are W1C style registers, to the memset does not actually clear them. Signed-off-by:

No reason to wrap counter values at 2^32. Especially the bytes counters can wrap pretty fast on Gbit networks. Signed-off-by:

No reason to produce the legacy net_device_stats struct, only to have it converted to rtnl_link_stats64. And as a bonus, this allows for improving counter size to 64 bit. Signed-off-by:

Karsten Graul says: ==================== net/smc: Add SMC statistic support Please apply the following patch series for smc to netdev's net-next tree. This v2 is a resend of the code contained in v1 but with an updated cover letter to describe why we have chosen to use the generic netlink mechanism to access the smc protocol's statistic data. The patchset adds statistic support to the SMC protocol. Per-cpu variables are used to collect the statistic information for better performance and for reducing concurrency pitfalls. The code that is collecting statistic data is implemented in macros to increase code reuse and readability. The generic netlink mechanism in SMC is extended to provide the collected statistics to userspace. Network namespace awareness is also part of the statistics implementation. SMC is a protocol interacting with PCI devices (like RoCE Cards) and runs on top of the TCP protocol. As SMC is a network protocol and not an ethernet device driver, we decided to use the generic netlink interface. This should be comparable to what other protocols in the net subsystem like tipc, ncsi, ieee802154 or tcp, et al, do. There is already an established internal generic netlink interface mechanism in SMC which is used to collect SMC Protocol internal information. This patchset extends that existing mechanism. ==================== Signed-off-by: -

Fill in code stub to check that the flow actions are valid for merge. The actions of the flow X should not conflict with the matches of flow X+1. For now this check is quite strict and set_actions are very limited, will need to update this when NAT support is added. Signed-off-by:

Replace merge check stub code with the actual implementation. This checks that the match parts of two tc flows does not conflict. Only overlapping keys needs to be checked, and only the narrowest masked parts needs to be checked, so each key is masked with the AND'd result of both masks before comparing. Signed-off-by:

The nft flow will be destroyed after offload cb returns. This means we need save a full copy of it since it can be referenced through other paths other than just the offload cb, for example when a new pre_ct or post_ct entry is added, and it needs to be merged with an existing nft entry. Signed-off-by:

Louis Peens authored
Implement code to add and remove nft flows to the relevant list. Registering and deregistering the callback function for the nft table is quite complicated. The safest is to delete the callback on the removal of the last pre_ct flow. This is because if this is also the latest pre_ct flow in software it means that this specific nft table will be freed, so there will not be a later opportunity to do this. Another place where it looks possible to delete the callback is when the last nft_flow is deleted, but this happens under the flow_table lock, which is also taken when deregistering the callback, leading to a deadlock situation. This means the final solution here is to delete the callback when removing the last pre_ct flow, and then clean up any remaining nft_flow entries which may still be present, since there will never be a callback now to do this, leaving them orphaned if not cleaned up here as well.

Louis Peens authored
Add register/unregister of the nft callback. For now just add stub code to accept the flows, but don't do anything with it. Decided to accept the flows since netfilter will keep on trying to offload a flow if it was rejected, which is quite noisy. Follow-up patches will start implementing the functions to add nft flows to the relevant tables. Signed-off-by:

Louis Peens authored
Add functions to handle delete flow callbacks for ct flows. Also accept the flows for offloading by returning 0 instead of -EOPNOTSUPP. Flows will still not actually be offloaded to hw, but at this point it's difficult to not accept the flows and also exercise the cleanup paths properly. Traffic will still be handled safely through the fallback path. Signed-off-by:
