The MT8183 has not one but two efuse devices. The static name and ID causes the second efuse device to fail to probe, due to duplicate sysfs entries. With the rework of the mtk-socinfo driver, lookup by name is no longer necessary. The custom name can simply be dropped.

2024-03-07cdrom: gdrom: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Add of_match table for "ti,amc6821" compatible string. This fixes automatic driver loading by userspace when using device-tree, and if built as a module like major linux distributions do. While devices probe just fine with i2c_device_id table, userspace can't match the "ti,amc6821" compatible string from dt with the plain "amc6821" device id.

2024-03-07s390/zcrypt: improve zcrypt retry behaviorHarald Freudenberger3-80/+58
This patch reworks and improves the zcrypt retry behavior: - The zcrypt_rescan_req counter has been removed. This counter variable has been increased on some transport errors and was used as a gatekeeper for AP bus rescans. - Rework of the zcrypt_process_rescan() function to not use the above counter variable any more. Instead now always the ap_bus_force_rescan() function is called (as this has been improved with a previous patch). - As the zcrpyt_process_rescan() function is called in all cprb send functions in case of the first attempt to send failed with ENODEV now before the next attempt to send an cprb is started. - Introduce a define ZCRYPT_WAIT_BINDINGS_COMPLETE_MS for the amount of milliseconds to have the zcrypt API wait for AP bindings complete. This amount has been reduced to 30s (was 60s). Some playing around showed that 30s is a really fair limit. The result of the above together with the patches to improve the AP scan bus functions is that after the first loop of cprb send retries when the result is a ENODEV the AP bus scan is always triggered (synchronous). If the AP bus scan detects changes in the configuration, all the send functions now retry when the first attempt was failing with ENODEV in the hope that now a suitable device has appeared. About concurrency: The ap_bus_force_rescan() uses a mutex to ensure only one active AP bus scan is running. Another caller of this function is blocked as long as the scan is running but does not cause yet another scan. Instead the result of the 'other' scan is used. This affects only tasks which run into an initial ENODEV. Tasks with successful delivery of cprbs will never invoke the bus scan and thus never get blocked by the mutex.

2024-03-07s390/zcrypt: introduce retries on in-kernel send CPRB functionsHarald Freudenberger1-2/+40
The both functions zcrypt_send_cprb() and zcrypt_send_ep11_cprb() are used to send CPRBs in-kernel from different sources. For example the pkey module may call one of the functions in zcrypt_ep11misc.c to trigger a derive of a protected key from a secure key blob via an existing crypto card. These both functions are then the internal API to send the CPRB and receive the response. All the ioctl functions to send an CPRB down to the addressed crypto card use some kind of retry mechanism. When the first attempt fails with ENODEV, a bus rescan is triggered and a loop with retries is carried out. For the both named internal functions there was never any retry attempt made. This patch now introduces the retry code even for this both internal functions to have effectively same behavior on sending an CPRB from an in-kernel source and sending an CPRB from userspace via ioctl.

2024-03-07s390/ap: introduce mutex to lock the AP bus scanHarald Freudenberger2-11/+58
Rework the invocations around ap_scan_bus(): - Protect ap_scan_bus() with a mutex to make sure only one scan at a time is running. - The workqueue invocation which is triggered by either the module init or via AP bus scan timer expiration uses this mutex and if there is already a scan running, the work is simple aborted (as the job is done by another task). - The ap_bus_force_rescan() which is invoked by higher level layers mostly on failures which indicate a bus scan may help is reworked to call ap_scan_bus() direct instead of enqueuing work into a system workqueue and waiting for that to finish. Of course the mutex is respected and in case of another task already running a bus scan the shortcut of waiting for this scan to finish and reusing the scan result is taken.

2024-03-07s390/ap: rearm APQNs bindings complete completionHarald Freudenberger3-21/+80
The APQN bindings complete completion was used to reflect that 1st the AP bus initial scan is done and 2nd all the detected APQNs have been bound to a device driver. This was a single-shot action. However, as the AP bus supports hot-plug it may be that new APQNs appear reflected as new AP queue and card devices which need to be bound to appropriate device drivers. So the condition that all existing AP queue devices are bound to device drivers may go away for a certain time. This patch now checks during AP bus scan for maybe new AP devices appearing and does a re-init of the internal completion variable. So the AP bus function ap_wait_apqn_bindings_complete() now may block on this condition variable even later after initial scan is through when new APQNs appear which need to get bound. This patch also moves the check for binding complete invocation from the probe function to the end of the AP bus scan function. This change also covers some weird scenarios where during a card hotplug the binding of the card device was sufficient for binding complete but the queue devices where still in the process of being discovered. As of now this change has no impact on existing code. The behavior change in the now later bindings complete should not impact any code (and has been tested so far). The only exploiter is the zcrypt function zcrypt_wait_api_operational() which only initial calls ap_wait_apqn_bindings_complete(). However, this new behavior of the AP bus wait for APQNs bindings complete function will be used in a later patch exploiting this for the zcrypt API layer.

Update vfio_ap_mdev_reset_queue() to handle an unexpected checkstop (hardware error) the same as the deconfigured case. This prevents unexpected and unhelpful warnings in the event of a hardware error. We also stop lying about a queue's reset response code. This was originally done so we could force vfio_ap_mdev_filter_matrix to pass a deconfigured device through to the guest for the hotplug scenario. vfio_ap_mdev_filter_matrix is instead modified to allow passthrough for all queues with reset state normal, deconfigured, or checkstopped.

2024-03-07powerpc/macio: Make remove callback of macio driver void returnedDawei Li7-25/+8
Commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller. This change is for macio bus based drivers.

2024-03-07net: pds_core: Fix possible double free in error handling pathYongzhi Liu1-8/+4
When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release calls kfree(padev) to free memory. We shouldn't call kfree(padev) again in the error handling path. Fix this by cleaning up the redundant kfree() and putting the error handling back to where the errors happened.

2024-03-07drm/etnaviv: Restore some id valuesChristian Gmeiner2-1/+10
The hwdb selection logic as a feature that allows it to mark some fields as 'don't care'. If we match with such a field we memcpy(..) the current etnaviv_chip_identity into ident. This step can overwrite some id values read from the GPU with the 'don't care' value. Fix this issue by restoring the affected values after the memcpy(..). As this is crucial for user space to know when this feature works as expected increment the minor version too.

2024-03-07RDMA/mana_ib: Use virtual address in dma regions for MRsKonstantin Taranov6-20/+45
Introduce mana_ib_create_dma_region() to create dma regions with iova for MRs. It allows creating MRs with any page offset. Previously, only page-aligned addresses worked. For dma regions that must have a zero dma offset (e.g., for queues), mana_ib_create_zero_offset_dma_region() is added. To get the zero offset, ib_umem_find_best_pgoff() is used with zero pgoff_bitmask.

2024-03-07RDMA/hns: Append SCC context to the raw dump of QPCwenglianfa5-3/+55
SCCC (SCC Context) is a context with QP granularity that contains information about congestion control. Dump SCCC and QPC together to improve troubleshooting. When dumping raw QPC with rdmatool, there will be a total of 576 bytes data output, where the first 512 bytes is QPC and the last 64 bytes is SCCC. When congestion control is disabled, the 64 byte SCCC will be all 0. Example: $rdma res show qp -jpr [ { "ifindex": 0, "ifname": "hns_0", "data": [ 67,0,0,0... 512bytes 4,0,2... 64bytes] },... } ] Signed-off-by: wenglianfa <[email protected]> Signed-off-by: Junxian Huang <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Leon Romanovsky <[email protected]>
