2023-01-19devlink: protect health reporter operation with instance lockJiri Pirko
Similar to other devlink objects, protect the reporters list by devlink instance lock. Alongside add unlocked versions of health reporter create/destroy functions and use them in drivers on call paths where the instance lock is held.

2023-01-19net/mlx5e: Create separate devlink instance for ethernet auxiliary deviceJiri Pirko
The fact that devlink instance lock is held over mlx5 auxiliary devices probe and remove routines brought a need to conditionally take devlink instance lock there. The code is checking a MLX5E_LOCKED_FLOW flag in mlx5 priv struct. This is racy and may lead to access devlink objects without holding instance lock or deadlock. To avoid this, the only lock-wise sane solution is to make the devlink entities created by the auxiliary device independent on the original pci devlink instance. Create devlink instance for the auxiliary device and put the uplink port instance there alongside with the port health reporters.

In the am65_cpsw_init_serdes_phy() function, the error handling for the call to the devm_of_phy_get() function misses the case where the return value of devm_of_phy_get() is ERR_PTR(-EPROBE_DEFER).

Avoid race between process wakeup and tpacket_v3 block timeout. The test waits for cfg_timeout_msec for packets to arrive. Packets arrive in tpacket_v3 rings, which pass packets ("frames") to the process in batches ("blocks"). The sk waits for req3.tp_retire_blk_tov msec to release a block. Set the block timeout lower than the process waiting time, else the process may find that no block has been released by the time it scans the socket list.

The referenced commit changed the error code returned by the kernel when preventing a non-established socket from attaching the ktls ULP. Before to such a commit, the user-space got ENOTCONN instead of EINVAL. The existing self-tests depend on such error code, and the change caused a failure: RUN global.non_established ... tls.c:1673:non_established:Expected errno (22) == ENOTCONN (107) non_established: Test failed at step #3 FAIL global.non_established In the unlikely event existing applications do the same, address the issue by restoring the prior error code in the above scenario. Note that the only other ULP performing similar checks at init time - smc_ulp_ops - also fails with ENOTCONN when trying to attach the ULP to a non-established socket.

2023-01-19ice: restrict PTP HW clock freq adjustments to 100, 000, 000 PPBSiddaraju DH
The PHY provides only 39b timestamp. With current timing implementation, we discard lower 7b, leaving 32b timestamp. The driver reconstructs the full 64b timestamp by correlating the 32b timestamp with cached_time for performance. The reconstruction algorithm does both forward & backward interpolation. The 32b timeval has overflow duration of 2^32 counts ~= 4.23 second. Due to interpolation in both direction, its now ~= 2.125 second IIRC, going with at least half a duration, the cached_time is updated with periodic thread of 1 second (worst-case) periodicity. But the 1 second periodicity is based on System-timer. With PPB adjustments, if the 1588 timers increments at say double the rate, (2s in-place of 1s), the Nyquist rate/half duration sampling/update of cached_time with 1 second periodic thread will lead to incorrect interpolations. Hence we should restrict the PPB adjustments to at least half duration of cached_time update which translates to 500,000,000 PPB. Since the periodicity of the cached-time system thread can vary, it is good to have some buffer time and considering practicality of PPB adjustments, limiting the max_adj to 100,000,000.

2023-01-19ice: Handle LLDP MIB Pending changeAnatolii Gerasymenko
If the number of Traffic Classes (TC) is decreased, the FW will no longer remove TC nodes, but will send a pending change notification. This will allow RDMA to destroy corresponding Control QP markers. After RDMA finishes outstanding operations, the ice driver will send an execute MIB Pending change admin queue command to FW to finish DCB configuration change. The FW will buffer all incoming Pending changes, so there can be only one active Pending change. RDMA driver guarantees to remove Control QP markers within 5000 ms. Hence, LLDP response timeout txTTL (default 30 sec) will be met. In the case of a Pending change, LLDP MIB Change Event (opcode 0x0A01) will contain the whole new MIB. But Get LLDP MIB (opcode 0x0A00) AQ call would still return an old MIB, as the Pending change hasn't been applied yet. Add ice_get_dcb_cfg_from_mib_change() function to retrieve DCBX config from LLDP MIB Change Event's buffer for Pending changes.

2023-01-19ice: Add 'Execute Pending LLDP MIB' Admin Queue commandTsotne Chakhvadze
In DCB Willing Mode (FW managed LLDP), when the link partner changes configuration which requires fewer TCs, the TCs that are no longer needed are suspended by EMP FW, removed, and never resumed. This occurs before a MIB change event is indicated to SW. The permanent suspension and removal of these TC nodes in the scheduler prevents RDMA from being able to destroy QPs associated with this TC, requiring a CORE reset to recover. A new DCBX configuration change flow is defined to allow SW driver and other SW components (RDMA) to properly adjust to the configuration changes before they are taking effect in HW. This flow includes a two-way handshake between EMP FW<->LAN SW<->RDMA SW. List of changes: - Add 'Execute Pending LLDP MIB' AQC. - Add 'Pending Event Enable' bit. - Add additional logic to ignore Pending Event Enable' request while 'LLDP MIB Chnage' event is disabled. - Add 'Execute Pending LLDP MIB' AQC sending function to FW, which is needed to take place MIB Event change.

2023-01-19net: phy: Remove probe_capabilitiesAndrew Lunn
Deciding if to probe of PHYs using C45 is now determine by if the bus provides the C45 read method. This makes probe_capabilities redundant so remove it.

2023-01-19net: phy: Decide on C45 capabilities based on presence of methodAndrew Lunn
Some PHYs provide invalid IDs in C22 space. If C45 is supported on the bus an attempt can be made to get the IDs from the C45 space. Decide on this based on the presence of the C45 read method in the bus structure. This will allow the unreliable probe_capabilities to be removed.

Now that all MDIO bus drivers which set probe_capabilities to MDIOBUS_C22_C45 have been converted to use the name API for C45 transactions, perform the scanning of the bus based on which methods the bus provides.

2023-01-19net: mdio: Add workaround for Micrel PHYs which are not C45 compatibleAndrew Lunn
After scanning the bus for C22 devices, check if any Micrel PHYs have been found. They are known to do bad things if there are C45 transactions on the bus. Prevent the scanning of the bus using C45 if such a PHY has been detected.

2023-01-19net: mdio: Rework scanning of bus ready for quirksAndrew Lunn
Some C22 PHYs do bad things when there are C45 transactions on the bus. In order to handle this, the bus needs to be scanned first for C22 at all addresses, and then C45 scanned for all addresses. The Marvell pxa168 driver scans a specific address on the bus to find its PHY. This is a C22 only device, so update it to use the c22 helper.

2023-01-19bitfield: add FIELD_PREP_CONST()Johannes Berg
Neither FIELD_PREP() nor *_encode_bits() can be used in constant contexts (such as initializers), but we don't want to define shift constants for all masks just for use in initializers, and having checks that the values fit is also useful. Therefore, add FIELD_PREP_CONST() which is a smaller version of FIELD_PREP() that can only take constant arguments and has less friendly (but not less strict) error checks, and expands to a constant value.
