git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2021-09-30 1) From Yevgeny Kliteynik: This patch series deals with vport handling in SW steering. For every vport, SW steering queries FW for this vport's properties, such as RX/TX ICM addresses to be able to add this vport as dest action. The following patches rework vport capabilities managements and add support for Scalable Functions (SFs). - Patch 1 fixes the vport number data type all over the DR code to 16 bits in accordance with HW spec. - Patch 2 replaces local SW steering WIRE_PORT macro with the existing mlx5 define. - Patch 3 adds missing query for vport 0 and and handles eswitch manager capabilities for ECPF (BlueField in embedded CPU mode). - Patch 4 fixes error messages for failure to obtain vport caps from different locations in the code to have the same verbosity level and similar wording. - Patch 5 adds support for csum recalculation flow tables on SFs: it implements these FTs management in XArray instead of the fixed size array, thus adding support for csum recalculation table for any valid vport. - Patch 6 is the main patch of this whole series: it refactors vports capabilities handling and adds SFs support. 2) Minor and trivial updates and cleanups * tag 'mlx5-updates-2021-09-30' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5e: Use array_size() helper net/mlx5: Use struct_size() helper in kvzalloc() net/mlx5: Use kvcalloc() instead of kvzalloc() net/mlx5: Tolerate failures in debug features while driver load net/mlx5: Warn for devlink reload when there are VFs alive net/mlx5: DR, Add missing string for action type SAMPLER net/mlx5: DR, init_next_match only if needed net/mlx5: DR, Fix typo 'offeset' to 'offset' net/mlx5: DR, Increase supported num of actions to 32 net/mlx5: DR, Add support for SF vports net/mlx5: DR, Support csum recalculation flow table on SFs net/mlx5: DR, Align error messages for failure to obtain vport caps net/mlx5: DR, Add missing query for vport 0 net/mlx5: DR, Replace local WIRE_PORT macro with the existing MLX5_VPORT_UPLINK net/mlx5: DR, Fix vport number data type to u16 ==================== Link: https://lore.kernel.org/r/20210930232050.41779-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-10-01bpf/tests: Add test of LDX_MEM with operand aliasingJohan Almbladh1-0/+58
This patch adds a set of tests of BPF_LDX_MEM where both operand registers are the same register. Mainly testing 32-bit JITs that may load a 64-bit value in two 32-bit loads, and must not overwrite the address register.

This patch expands the register-clobbering-during-function-call tests to cover more all ALU32/64 MUL, DIV and MOD operations and all ATOMIC operations. In short, if a JIT implements a complex operation with a call to an external function, it must make sure to save and restore all its caller-saved registers that may be clobbered by the call.

2021-10-01bpf/tests: Add zero-extension checks in BPF_ATOMIC testsJohan Almbladh1-5/+17
This patch updates the existing tests of BPF_ATOMIC operations to verify that a 32-bit register operand is properly zero-extended. In particular, it checks the operation on archs that require 32-bit operands to be properly zero-/sign-extended or the result is undefined, e.g. MIPS64.

2021-10-01devlink: report maximum number of snapshots with regionsJacob Keller4-2/+13
Each region has an independently configurable number of maximum snapshots. This information is not reported to userspace, making it not very discoverable. Fix this by adding a new DEVLINK_ATTR_REGION_MAX_SNAPSHOST attribute which is used to report this maximum. Ex: $devlink region pci/0000:af:00.0/nvm-flash: size 10485760 snapshot [] max 1 pci/0000:af:00.0/device-caps: size 4096 snapshot [] max 10 pci/0000:af:00.1/nvm-flash: size 10485760 snapshot [] max 1 pci/0000:af:00.1/device-caps: size 4096 snapshot [] max 10 This information enables users to understand why a new region command may fail due to having too many existing snapshots.

2021-10-01net/mlx5: DR, Add support for SF vportsYevgeny Kliteynik5-68/+120
Move all the vport capabilities to a separate struct and store vport caps in XArray: SFs vport numbers will not come in the same range as VF vports, so the existing implementation of vport capabilities as a fixed size array is not suitable here. XArray is a perfect fit: it is efficient when the indices used are densely clustered. In addition to being a perfect fit as a dynamic data structure, XArray also provides locking - it uses RCU and an internal spinlock to synchronise access, so no additional protection needed. Now except for the eswitch manager vport, all other vports (including the uplink vport) are handled in the same way: when a new go-to-vport action is added, this vport's caps are loaded from the xarray. If it is the first time for this particular vport number, then its capabilities are queried from FW and filled in into the appropriate entry.

Currently, vport 0 capabilities are not set. To fix this, we now querying both eswitch manager and vport 0. Eswitch manager has an access to all the vports - for eswitch manager PF, all vports can be referred as other vports. The exception is embedded CPU mode, where there is vport 0 of ECPF and the PF vport 0. Here is how vport are queried: For Connect-X5/6: PF vport (0) and vports 1..n: vport number, other = true esw_manager is vport 0 (PF) For BlueField (in embedded CPU mode): ECPF vport: vport = 0, other = false PF vport (0) and 1..n: vport number, other = true esw_manager = vport 0 (ECPF) Also, note that there's no need for other_vport function parameter in dr_domain_query_vport - this value is now deduced locally in the function.

2021-10-01selftests/bpf: Use kselftest skip code for skipped testsPo-Hsu Lin2-3/+9
There are several test cases in the bpf directory are still using exit 0 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in bpf directory: grep -r "exit 0" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

2021-10-01net/mlx5e: Mutually exclude setting of TX-port-TS and MQPRIO in channel modeAya Levin2-0/+19
TX-port-TS hijacks the PTP traffic to a specific HW TX-queue. This conflicts with MQPRIO in channel mode, which specifies explicitly which TC accepts the packet. This patch mutually excludes the above configuration.

2021-10-01net/mlx5e: Fix the presented RQ index in PTP statsLama Kayal3-3/+5
PTP-RQ counters title format contains PTP-RQ identifier, which is mistakenly not passed to sprinft(). This leads to unexpected garbage values instead. This patch fixes it.

2021-10-01net/mlx5: Avoid generating event after PPS out in Real time modeAya Levin1-8/+6
When in Real-time mode, HW clock is synced with the PTP daemon. Hence driver should not re-calibrate the next pulse (via MTPPSE repetitive events mechanism). This patch arms repetitive events only in free-running mode.
