Florian Fainelli says: ==================== net: dsa: bcm_sf2: Add support for CFP statistics The Broadcom SF2 switch has a Compact Field Processor (CFP) which not only can perform matching + action, but also counts the number of times a rule has been hit. This is invaluable while debugging when/if rules are not matched. ==================== Signed-off-by: -

When the source and destination port of a CFP rule match, we must set the loopback bit enable to allow that, otherwise the frame is discarded. Signed-off-by:

The link status value latches link-down events. To get the current status we read the register twice in genphy_update_link(). There's a potential risk that we miss a link-down event in polling mode. This may cause issues if the user e.g. connects his machine to a different network. On the other hand reading the latched value may cause issues in interrupt mode. Following scenario: - After boot link goes up - phy_start() is called triggering an aneg restart, hence link goes down and link-down info is latched. - After aneg has finished link goes up and triggers an interrupt. Interrupt handler reads link status, means it reads the latched "link is down" info. But there won't be another interrupt as long as link stays up, therefore phylib will never recognize that link is up. Deal with both scenarios by reading the register twice in interrupt mode only.

Ido Schimmel says: ==================== mlxsw: Implement periodic ERP rehash Currently, an ERP set is created for each region according to rules inserted and order of their insertion. However that might lead to suboptimal ERP sets and possible unnecessary spillage into C-TCAM. This patchset aims to fix this problem and introduces periodical checking of used ERP sets and in case a better ERP set is possible for the given set of rules, it rehashes the region to use the better ERP set. Patch 1 prepares devlink params infra in order to fix the init/fini sequences. Patch 2 implements hints infra in objagg library. Patch 3 fixes a typo Patch 4 adds number of root objects directly into objagg stats. Patches 5-7 do split of multiple structs in Spectrum TCAM code. Patch 8 introduces initial implementation of ERP rehash logic, according to objagg hints. Patch 9 adds hints priv passing trought the layers. Patch 10 adds multi field into PAGT reg. (new patch) Patch 11 implements actual region rules migration in TCAM code. Patch 12 adds a devlink param so user is able to control rehash interval. Patch 13 adds couple of tracepoints in order to track rehash procedures. Patch 14 adds a simple selftest to test region rehash. ==================== Signed-off-by: -

If the hints are returned, the migration should be started. For that to happen, there is a need to create a second physical region in TCAM with new ERP set by passing the hints and then move chunk by chunk, entry by entry. During the transition, two lookups will occur. One in old region and another in new region. The highest priority rule will be chosen. In an unlikely case that the migration will fail and also rollback to original region will fail the vregion will become in bad state. Everything will work, only no future rehash will be possible. In a follow-up work, this can be resolved by trying to resume the rollback in delayed work and repair the vregion. Signed-off-by:

The hints priv comes from ERP code and it is possible to obtain it from TCAM code. Add arg to appropriate functions so the hints priv could be passed back down to ERP code. Pass NULL now as the follow-up patches would pass an actual hints priv pointer. Signed-off-by:

Introduce an initial implementation of rehash logic in ERP code. Currently, the rehash is considered as needed only in case number of roots in the hints is smaller than the number of roots actually in use. In that case return hints pointer and let it be obtained through the callpath through the Spectrum-2 TCAM op. Signed-off-by:

Implement simple greedy algo to find more optimized root-delta tree for a given objagg instance. This "hints" can be used by a driver to: 1) check if the hints are better (driver's choice) than the original objagg tree. Driver does comparison of objagg stats and hints stats. 2) use the hints to create a new objagg instance which will construct the root-delta tree according to the passed hints. Currently, only a simple greedy algorithm is implemented. Basically it finds the roots according to the maximal possible user count including deltas. Signed-off-by:

Currently, user can do dump or get of param values right after the devlink params are registered. However the driver may not be initialized which is an issue. The same problem happens during notification upon param registration. Allow driver to publish devlink params whenever it is ready to handle get() ops. Note that this cannot be resolved by init reordering, as the "driverinit" params have to be available before the driver is initialized (it needs the param values there). Signed-off-by:

Right now ipvlan has a hard dependency on CONFIG_NETFILTER and otherwise it cannot be built. However, the only ipvlan operation mode that actually depends on netfilter is l3s, everything else is independent of it. Break this hard dependency such that users are able to use ipvlan l3 mode on systems where netfilter is not compiled in. Therefore, this adds a hidden CONFIG_IPVLAN_L3S bool which is defaulting to y when CONFIG_NETFILTER is set in order to retain existing behavior for l3s. All l3s related code is refactored into ipvlan_l3s.c that is compiled in when enabled. Signed-off-by:

Pull driver core fixes from Greg KH: "Here are some driver core fixes for 5.0-rc6. Well, not so much "driver core" as "debugfs". There's a lot of outstanding debugfs cleanup patches coming in through different subsystem trees, and in that process the debugfs core was found that it really should return errors when something bad happens, to prevent random files from showing up in the root of debugfs afterward. So debugfs was fixed up to handle this properly, and then two fixes for the relay and blk-mq code was needed as it was making invalid assumptions about debugfs return values.
