2024-08-23platform/x86/amd/pmc: Fix SMU command submission path on new AMD platformShyam Sundar S K
The commit 426463d94d45 ("platform/x86/amd/pmc: Send OS_HINT command for new AMD platform") was introduced to enable sending mailbox commands to PMFW on newer platforms. However, it was later discovered that the commit did not configure the correct message port ID (i.e., S2D or PMC). Without this configuration, all command submissions to PMFW are treated as invalid, leading to command failures. To address this issue, the CPU ID association for the new platform needs to be added in amd_pmc_get_ip_info(). This ensures that the correct SMU port IDs are selected.

2024-08-23net: sfp: Add helper to return the SFP bus nameMaxime Chevallier
Knowing the bus name is helpful when we want to expose the link topology to userspace, add a helper to return the SFP bus name. This call will always be made while holding the RTNL which ensures that the SFP driver won't unbind from the device. The returned pointer to the bus name will only be used while RTNL is held.

2024-08-23net: phy: add helpers to handle sfp phy connect/disconnectMaxime Chevallier
There are a few PHY drivers that can handle SFP modules through their sfp_upstream_ops. Introduce Phylib helpers to keep track of connected SFP PHYs in a netdevice's namespace, by adding the SFP PHY to the upstream PHY's netdev's namespace. By doing so, these SFP PHYs can be enumerated and exposed to users, which will be able to use their capabilities.

2024-08-23net: phy: Introduce ethernet link topology representationMaxime Chevallier
Link topologies containing multiple network PHYs attached to the same net_device can be found when using a PHY as a media converter for use with an SFP connector, on which an SFP transceiver containing a PHY can be used. With the current model, the transceiver's PHY can't be used for operations such as cable testing, timestamping, macsec offload, etc. The reason being that most of the logic for these configuration, coming from either ethtool netlink or ioctls tend to use netdev->phydev, which in multi-phy systems will reference the PHY closest to the MAC. Introduce a numbering scheme allowing to enumerate PHY devices that belong to any netdev, which can in turn allow userspace to take more precise decisions with regard to each PHY's configuration. The numbering is maintained per-netdev, in a phy_device_list. The numbering works similarly to a netdevice's ifindex, with identifiers that are only recycled once INT_MAX has been reached. This prevents races that could occur between PHY listing and SFP transceiver removal/insertion. The identifiers are assigned at phy_attach time, as the numbering depends on the netdevice the phy is attached to. The PHY index can be re-used for PHYs that are persistent.

2024-08-23irqchip/gic-v3: Init SRE before poking sysregsMark Rutland
The GICv3 driver pokes GICv3 system registers in gic_prio_init() before gic_cpu_sys_reg_init() ensures that GICv3 system registers have been enabled by writing to ICC_SRE_EL1.SRE. On arm64 this is benign as has_useable_gicv3_cpuif() runs earlier during cpufeature detection, and this enables the GICv3 system registers. On 32-bit arm when booting on an FVP using the boot-wrapper, the accesses in gic_prio_init() end up being UNDEFINED and crashes the kernel during boot. This is a regression introduced by the addition of gic_prio_init(). Fix this by factoring out the SRE initialization into a new function and calling it early in the three paths where SRE may not have been initialized: (1) gic_init_bases(), before the primary CPU pokes GICv3 sysregs in gic_prio_init(). (2) gic_starting_cpu(), before secondary CPUs initialize GICv3 sysregs in gic_cpu_init(). (3) gic_cpu_pm_notifier(), before CPUs re-initialize GICv3 sysregs in gic_cpu_sys_reg_init().

2024-08-23OPP: Fix support for required OPPs for multiple PM domainsUlf Hansson
It has turned out that having _set_required_opps() to recursively call dev_pm_opp_set_opp() to set the required OPPs, doesn't really work as well as we expected. More precisely, at each recursive call to dev_pm_opp_set_opp() we are changing an OPP for a required_dev that belongs to a required-OPP table. The problem with this, is that we may have several devices sharing the same required-OPP table, which leads to an incorrect behaviour in regards to aggregating the per device votes. To fix the problem for a required-OPP table belonging to a PM domain, which is the only existing usecase for now, let's simply replace the call to dev_pm_opp_set_opp() in _set_required_opps() by a call to _set_opp_level(). Moving forward we may potentially need to add support for other types of required-OPP tables. In this case, the aggregation needs to be thought of.

2024-08-23iommu: Handle iommu faults for a bad iopf setupPranjal Shrivastava
The iommu_report_device_fault function was updated to return void while assuming that drivers only need to call iommu_report_device_fault() for reporting an iopf. This implementation causes following problems: 1. The drivers rely on the core code to call it's page_reponse, however, when a fault is received and no fault capable domain is attached / iopf_param is NULL, the ops->page_response is NOT called causing the device to stall in case the fault type was PAGE_REQ. 2. The arm_smmu_v3 driver relies on the returned value to log errors returning void from iommu_report_device_fault causes these events to be missed while logging. Modify the iommu_report_device_fault function to return -EINVAL for cases where no fault capable domain is attached or iopf_param was NULL and calls back to the driver (ops->page_response) in case the fault type was IOMMU_FAULT_PAGE_REQ. The returned value can be used by the drivers to log the fault/event as needed.

2024-08-22scsi: sd: Ignore command SYNCHRONIZE CACHE error if format in progressYihang Li
If formatting a suspended disk (such as formatting with different DIF type), the disk will be resuming first, and then the format command will submit to the disk through SG_IO ioctl. When the disk is processing the format command, the system does not submit other commands to the disk. Therefore, the system attempts to suspend the disk again and sends the SYNCHRONIZE CACHE command. However, the SYNCHRONIZE CACHE command will fail because the disk is in the formatting process. This will cause the runtime_status of the disk to error and it is difficult for user to recover it. Error info like: [ 669.925325] sd 6:0:6:0: [sdg] Synchronizing SCSI cache [ 670.202371] sd 6:0:6:0: [sdg] Synchronize Cache(10) failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK [ 670.216300] sd 6:0:6:0: [sdg] Sense Key : 0x2 [current] [ 670.221860] sd 6:0:6:0: [sdg] ASC=0x4 ASCQ=0x4 To solve the issue, ignore the error and return success/0 when format is in progress.

If aac_init_adapter() fails after allocating memory for aac_dev::queues, it frees the memory but does not clear that member. After the hardware-specific init function returns an error, aac_probe_one() goes down an error path that frees the memory pointed to by aac_dev::queues, resulting.in a double-free.

And as cfg->tcs is a u8, the range is 0 - 255. Further, on inspecting the code, it seems that cfg->tcs will never be more than AQ_CFG_TCS_MAX (8), so the range is actually 0 - 8. So, it seems that the condition that GCC flags will not occur. But, nonetheless, it would be nice if it didn't emit the warning. It seems that this can be achieved by changing the format specifier from %d to %u, in which case I believe GCC recognises an upper bound on the range of tc of 0 - 255. After some experimentation I think this is due to the combination of the use of %u and the type of cfg->tcs (u8). Empirically, updating the type of the tc variable to unsigned int has the same effect. As both of these changes seem to make sense in relation to what the code is actually doing - iterating over unsigned values - do both. Compile tested only.

2024-08-22nvme: move stopping keep-alive into nvme_uninit_ctrl()Ming Lei
Commit 4733b65d82bd ("nvme: start keep-alive after admin queue setup") moves starting keep-alive from nvme_start_ctrl() into nvme_init_ctrl_finish(), but don't move stopping keep-alive into nvme_uninit_ctrl(), so keep-alive work can be started and keep pending after failing to start controller, finally use-after-free is triggered if nvme host driver is unloaded. This patch fixes kernel panic when running nvme/004 in case that connection failure is triggered, by moving stopping keep-alive into nvme_uninit_ctrl(). This way is reasonable because keep-alive is now started in nvme_init_ctrl_finish().

There is a difference between TLS configured (ie the user has provisioned/requested a key) and TLS enabled (ie the connection is encrypted with TLS). This becomes important for secure concatenation, where the initial authentication is run on an unencrypted connection (ie with TLS configured, but not enabled), and then the queue is reset to run over TLS (ie TLS configured _and_ enabled). So to differentiate between those two states store the generated key in opts->tls_key (as we're using the same TLS key for all queues), the key serial of the resulting TLS handshake in ctrl->tls_pskid (to signal that TLS on the admin queue is enabled), and a simple flag for the queues to indicated that TLS has been enabled.

An original (version 0) identifier has the form: NVMe0<type><hmac> <hostnqn> <subsysnqn> and a version 1 identifier has the form: NVMe1<type><hmac> <hostnqn> <subsysnqn> <hash> This patch modifies the lookup algorthm to compare only the first part of the identifier (excluding the hash value) to handle both version 0 and version 1 identifiers.

Use async function calls to make namespace scanning happen in parallel. Without the patch, NVME namespaces are scanned serially, so it can take a long time for all of a controller's namespaces to become available, especially with a slower (TCP) interface with large number of namespaces. It is not uncommon to have large numbers (hundreds or thousands) of namespaces on nvme-of with storage servers. The time it took for all namespaces to show up after connecting (via TCP) to a controller with 1002 namespaces was measured on one system: network latency without patch with patch 0 6s 1s 50ms 210s 10s 100ms 417s 18s Measurements taken on another system show the effect of the patch on the time nvme_scan_work() took to complete, when connecting to a linux nvme-of target with varying numbers of namespaces, on a network of 400us. namespaces without patch with patch 1 16ms 14ms 2 24ms 16ms 4 49ms 22ms 8 101ms 33ms 16 207ms 56ms 100 1.4s 0.6s 1000 12.9s 2.0s On the same system, connecting to a local PCIe NVMe drive (a Samsung PM1733) instead of a network target: namespaces without patch with patch 1 13ms 12ms 2 41ms 13ms Signed-off-by: Stuart Hayes <stuart.w.hayes@gmail.com> Reviewed-by: Sagi Grimberg <sagi@grimberg.me>

Make the mlxsw core_thermal driver use the .should_bind() thermal zone callback to provide the thermal core with the information on whether or not to bind the given cooling device to the given trip point in the given thermal zone. If it returns 'true', the thermal core will bind the cooling device to the trip and the corresponding unbinding will be taken care of automatically by the core on the removal of the involved thermal zone or cooling device. It replaces the .bind() and .unbind() thermal zone callbacks (in 3 places) which assumed the same trip points ordering in the driver and in the thermal core (that may not be true any more in the future). The .bind() callbacks used loops over trip point indices to call thermal_zone_bind_cooling_device() for the same cdev (once it had been verified) and all of the trip points, but they passed different 'upper' and 'lower' values to it for each trip. To retain the original functionality, the .should_bind() callbacks need to use the same 'upper' and 'lower' values that would be used by the corresponding .bind() callbacks when they are about to return 'true'. To that end, the 'priv' field of each trip is set during the thermal zone initialization to point to the corresponding 'state' object containing the maximum and minimum cooling states of the cooling device.

If it returns 'true', the thermal core will bind the cooling device to the trip and the corresponding unbinding will be taken care of automatically by the core on the removal of the involved thermal zone or cooling device. The previously existing acerhdf_bind() function bound cooling devices to thermal trip point 0 only, so the new callback needs to return 'true' for trip point 0. However, it is straightforward to observe that trip point 0 is an active trip point and the only other trip point in the driver's thermal zone is a critical one, so it is sufficient to return 'true' from that callback if the type of the given trip point is THERMAL_TRIP_ACTIVE.
