Jakub Kicinski says: ==================== nfp: tls: implement the stream sync RX resync This small series adds support for using the device in stream scan RX resync mode which improves the RX resync success rate. Without stream scan it's pretty much impossible to successfully resync a continuous stream. ==================== Signed-off-by: -
Jakub Kicinski authored
The simple RX resync strategy controlled by the kernel does not guarantee as good results as if the device helps by detecting the potential record boundaries and keeping track of them. We've called this strategy stream scan in the tls-offload doc. Implement this strategy for the NFP. The device sends a request for record boundary confirmation, which is then recorded in per-TLS socket state and responded to once record is reached. Because the device keeps track of records passing after the request was sent the response is not as latency sensitive as when kernel just tries to tell the device the information about the next record.

John Hurley authored
A notifier is used to track route changes in the kernel. If a change is made to a route that is offloaded to fw then an update is sent to the NIC. The driver tracks all routes that are offloaded to determine if a kernel change is of interest. Extend the notifier to track IPv6 route changes and create a new list that stores offloaded IPv6 routes. Modify the IPv4 route helper functions to accept varying address lengths. This way, the same core functions can be used to handle IPv4 and IPv6. Signed-off-by:

When fw does not know the next hop for an IPv6 tunnel, it sends a request to the driver. Handle this request by doing a route lookup on the IPv6 address and offloading the next hop to the fw neighbour table. Similar functions already exist to handle IPv4 no neighbour requests. To avoid confusion, append these functions with the _ipv4 tag. There is no change in functionality with this. Signed-off-by:

The IPv4 set tunnel action allows the setting of tunnel metadata such as the TTL and ToS values. The pre-tunnel action includes the destination IP address and is used to calculate the next hop from from the neighbour table. Much of the IPv4 tunnel actions can be reused for IPv6 tunnels. Change the names of associated functions and structs to remove the IPv4 identifier and make minor modifcations to support IPv6 tunnel actions. Ensure the pre-tunnel action contains the IPv6 address along with an identifying flag when an IPv6 tunnel action is required. Signed-off-by:

In kernel 5.1, the flow offload API was introduced along with a helper function to extract the flow_rule from the TC offload struct. Each of the match helper functions are passed the offload struct and extract the flow rule to a local variable. Simplify the code while also removing the extra compat and local variable calls by extracting the rule once in the main match handler, and passing a reference to the rule direct to each helper.

Presently, at boot time, the comphys are enabled. For firmware compatibility reasons, the comphy driver does not power down the comphys at boot. Consequently, the ethernet comphys are left active until the network interfaces are brought through an up/down cycle. If the port is never used, the port wastes power needlessly. Arrange for the ethernet comphys to be cycled by the mvpp2 driver as if the interface went through an up/down cycle during driver probe, thereby powering them down. This saves: 270mW per 10G SFP+ port on the Macchiatobin Single Shot (eth0/eth1) 370mW per 10G PHY port on the Macchiatobin Double Shot (eth0/eth1) 160mW on the SFP port on either Macchiatobin flavour (eth3) Signed-off-by:

Russell King says: ==================== phylib consolidation Over the last few releases, there has been a push to clean up and consolidate the phylib code. Some cases have been missed, and this series catches those cases. 1. Remove redundant .aneg_done initialisers; calling genphy_aneg_done() for clause 22 PHYs is the default when .aneg_done is not set. 2. Some PHY drivers manually set phydev->pause and phydev->asym_pause, but we have a helper for this - phy_resolve_aneg_pause(), introduced in 2d880b87 ("net: phy: extract pause mode"). Use this in the lxt, marvell and uPD60620 drivers. Incidentally, this brings up the question whether marvell fiber mode is correctly interpreting and advertising the pause parameters. 3. Add a genphy_check_and_restart_aneg() helper, which complements the clause 45 version of this. This will be useful for PHY drivers that open code this logic (e.g. marvell.c) 4. Add a genphy_read_status_fixed() helper to read the fixed-mode status from a clause 22 PHY. lxt and marvell both contain copies of this code, so convert them over. 5. Arrange marvell driver to use genphy_read_lpa() for copper mode. This needs some rearrangement of the code in marvell_read_status_page_an(), but preserves using the PHY specific status register to derive the current negotiation results. 6. Simplify the marvell driver so we can use the genphy_read_status_fixed() helper directly rather than marvell_read_status_page_fixed(). 7. Use positive logic in the marvell driver to determine the link state, and get rid of the REGISTER_LINK_STATUS definition; we already have a definition for this. 8. The marvell driver reads the PHY specific status register multiple times when determining the status: once in marvell_update_link() and again in marvell_read_status_page_an(). This is a waste; rearrange to read the status register once, and pass its value into marvell_read_status_page_an(). We preserve using genphy_update_link() for the copper side. 9. The marvell driver was using private clause 37 definitions, but we have clause 37 definitions in uapi/linux/mii.h. Use the generic definitions. 10. Switch the marvell driver to use phy_modify_changed() to modify the fiber advertisement. 11. Switch the marvell driver to use genphy_check_and_restart_aneg() introduced above rather than open-coding this functionality. ==================== Signed-off-by:

marvell_read_status_page_an() always reads the PHY status register, but marvell_update_link() has already done this. Rather than wastefully reading the register twice in quick succession, read it once in marvell_read_status_page() and use the result for both.

Move the initialisation of the link partner state earlier, inside marvell_read_status_page(), so we don't have the same initialisation scattered amongst the other files. This is in a similar place to the genphy implementation, so would result in the same behaviour if a PHY read error occurs. This allows us to get rid of marvell_read_status_page_fixed(), which became a pointless wrapper around genphy_read_status_fixed(). Signed-off-by:

Petr Machata says: ==================== Add a new Qdisc, ETS The IEEE standard 802.1Qaz (and 802.1Q-2014) specifies four principal transmission selection algorithms: strict priority, credit-based shaper, ETS (bandwidth sharing), and vendor-specific. All these have their corresponding knobs in DCB. But DCB does not have interfaces to configure RED and ECN, unlike Qdiscs. In the Qdisc land, strict priority is implemented by PRIO. Credit-based transmission selection algorithm can then be modeled by having e.g. TBF or CBS Qdisc below some of the PRIO bands. ETS would then be modeled by placing a DRR Qdisc under the last PRIO band. The problem with this approach is that DRR on its own, as well as the combination of PRIO and DRR, are tricky to configure and tricky to offload to 802.1Qaz-compliant hardware. This is due to several reasons: - As any classful Qdisc, DRR supports adding classifiers to decide in which class to enqueue packets. Unlike PRIO, there's however no fallback in the form of priomap. A way to achieve classification based on packet priority is e.g. like this: # tc filter add dev swp1 root handle 1: \ basic match 'meta(priority eq 0)' flowid 1:10 Expressing the priomap in this manner however forces drivers to deep dive into the classifier block to parse the individual rules. A possible solution would be to extend the classes with a "defmap" a la split / defmap mechanism of CBQ, and introduce this as a last resort classification. However, unlike priomap, this doesn't have the guarantee of covering all priorities. Traffic whose priority is not covered is dropped by DRR as unclassified. But ASICs tend to implement dropping in the ACL block, not in scheduling pipelines. The need to treat these configurations correctly (if only to decide to not offload at all) complicates a driver. It's not clear how to retrofit priomap with all its benefits to DRR without changing it beyond recognition. - The interplay between PRIO and DRR is also causing problems. 802.1Qaz has all ETS TCs as a last resort. Switch ASICs that support ETS at all are likely to handle ETS traffic this way as well. However, the Linux model is more generic, allowing the DRR block in any band. Drivers would need to be careful to handle this case correctly, otherwise the offloaded model might not match the slow-path one. In a similar vein, PRIO and DRR need to agree on the list of priorities assigned to DRR. This is doubly problematic--the user needs to take care to keep the two in sync, and the driver needs to watch for any holes in DRR coverage and treat the traffic correctly, as discussed above. Note that at the time that DRR Qdisc is added, it has no classes, and thus any priorities assigned to that PRIO band are not covered. Thus this case is surprisingly rather common, and needs to be handled gracefully by the driver. - Similarly due to DRR flexibility, when a Qdisc (such as RED) is attached below it, it is not immediately clear which TC the class represents. This is unlike PRIO with its straightforward classid scheme. When DRR is combined with PRIO, the relationship between classes and TCs gets even more murky. This is a problem for users as well: the TC mapping is rather important for (devlink) shared buffer configuration and (ethtool) counters. So instead, this patch set introduces a new Qdisc, which is based on 802.1Qaz wording. It is PRIO-like in how it is configured, meaning one needs to specify how many bands there are, how many are strict and how many are ETS, quanta for the latter, and priomap. The new Qdisc operates like the PRIO / DRR combo would when configured as per the standard. The strict classes, if any, are tried for traffic first. When there's no traffic in any of the strict queues, the ETS ones (if any) are treated in the same way as in DRR. The chosen interface makes the overall system both reasonably easy to configure, and reasonably easy to offload. The extra code to support ETS in mlxsw (which already supports PRIO) is about 150 lines, of which perhaps 20 lines is bona fide new business logic. Credit-based shaping transmission selection algorithm can be configured by adding a CBS Qdisc under one of the strict bands (e.g. TBF can be used to a similar effect as well). As a non-work-conserving Qdisc, CBS can't be hooked under the ETS bands. This is detected and handled identically to DRR Qdisc at runtime. Note that offloading CBS is not subject of this patchset. The patchset proceeds in four stages: - Patches #1-#3 are cleanups. - Patches #4 and #5 contain the new Qdisc. - Patches #6 and #7 update mlxsw to offload the new Qdisc. - Patches #8-#10 add selftests for ETS. Examples: - Add a Qdisc with 6 bands, 3 strict and 3 ETS with 45%-30%-25% weights: # tc qdisc add dev swp1 root handle 1: \ ets strict 3 quanta 4500 3000 2500 priomap 0 1 1 1 2 3 4 5 # tc qdisc sh dev swp1 qdisc ets 1: root refcnt 2 bands 6 strict 3 quanta 4500 3000 2500 priomap 0 1 1 1 2 3 4 5 5 5 5 5 5 5 5 5 - Tweak quantum of one of the classes of the previous Qdisc: # tc class ch dev swp1 classid 1:4 ets quantum 1000 # tc qdisc sh dev swp1 qdisc ets 1: root refcnt 2 bands 6 strict 3 quanta 1000 3000 2500 priomap 0 1 1 1 2 3 4 5 5 5 5 5 5 5 5 5 # tc class ch dev swp1 classid 1:3 ets quantum 1000 Error: Strict bands do not have a configurable quantum. - Purely strict Qdisc with 1:1 mapping between priorities and TCs: # tc qdisc add dev swp1 root handle 1: \ ets strict 8 priomap 7 6 5 4 3 2 1 0 # tc qdisc sh dev swp1 qdisc ets 1: root refcnt 2 bands 8 strict 8 priomap 7 6 5 4 3 2 1 0 7 7 7 7 7 7 7 7 - Use "bands" to specify number of bands explicitly. Underspecified bands are implicitly ETS and their quantum is taken from MTU. The following thus gives each band the same weight: # tc qdisc add dev swp1 root handle 1: \ ets bands 8 priomap 7 6 5 4 3 2 1 0 # tc qdisc sh dev swp1 qdisc ets 1: root refcnt 2 bands 8 quanta 1514 1514 1514 1514 1514 1514 1514 1514 priomap 7 6 5 4 3 2 1 0 7 7 7 7 7 7 7 7 v2: - This addresses points raised by David Miller. - Patch #4: - sch_ets.c: Add a comment with description of the Qdisc and the dequeuing algorithm. - Kconfig: Add a high-level description to the help blurb. v1: - No changes, first upstream submission after RFC. v3 (internal): - This addresses review from Jiri Pirko. - Patch #3: - Rename to _HR_ instead of to _HIERARCHY_. - Patch #4: - pkt_sched.h: Keep all the TCA_ETS_ constants in one enum. - pkt_sched.h: Rename TCA_ETS_BANDS to _NBANDS, _STRICT to _NSTRICT, _BAND_QUANTUM to _QUANTA_BAND and _PMAP_BAND to _PRIOMAP_BAND. - sch_ets.c: Update to reflect the above changes.

This tests the newly-added ETS Qdisc. It runs two to three streams of traffic, each with a different priority. ETS Qdisc is supposed to allocate bandwidth according to the DRR algorithm and given weights. After running the traffic for a while, counters are compared for each stream to check that the expected ratio is in fact observed. In order for the DRR process to kick in, a traffic bottleneck must exist in the first place. In slow path, such bottleneck can be implemented by wrapping the ETS Qdisc inside a TBF or other shaper. This might however make the configuration unoffloadable. Instead, on HW datapath, the bottleneck would be set up by lowering port speed and configuring shared buffer suitably. Therefore the test is structured as a core component that implements the testing, with two wrapper scripts that implement the details of slow path resp. fast path configuration. Signed-off-by:
