2023-12-08crypto: sahara - fix processing requests with cryptlen < sg->lengthOvidiu Panait
It's not always the case that the entire sg entry needs to be processed. Currently, when cryptlen is less than sg->legth, "Descriptor length" errors are encountered. The error was noticed when testing xts(sahara-ecb-aes) with arbitrary sized input data. To fix this, take the actual request size into account when populating the hw links.

update() calls should not modify the result buffer, so add an additional check for "rctx->last" to make sure that only the final hash value is copied into the buffer.

2023-12-08crypto: sahara - fix cbc selftest failureOvidiu Panait
The kernel crypto API requires that all CBC implementations update the IV buffer to contain the last ciphertext block. This fixes the following cbc selftest error: alg: skcipher: sahara-cbc-aes encryption test failed (wrong output IV) on test vector 0, cfg="in-place (one sglist)" Fixes: 5de8875281e1 ("crypto: sahara - Add driver for SAHARA2 accelerator.")

2023-12-08crypto: sahara - remove FLAGS_NEW_KEY logicOvidiu Panait
Remove the FLAGS_NEW_KEY logic as it has the following issues: - the wrong key may end up being used when there are multiple data streams: t1 t2 setkey() encrypt() setkey() encrypt() encrypt() <--- key from t2 is used - switching between encryption and decryption with the same key is not possible, as the hdr flags are only updated when a new setkey() is performed With this change, the key is always sent along with the cryptdata when performing encryption/decryption operations.

2023-12-08crypto: octeontx2 - By default allocate one CPT LF per CPT VFBharat Bhushan
There are limited number CPT LFs (example 64 LFs on cn10k) and these LFs are allocated/attached to CPT VF on its creation. cptpf sysfs parameter "kvf_limits" defines number of CPT LFs per CPT VF. Default "kvf_limits" is initialized to zero and if kvf_limits is zero then number of LF allocated are equal to online cpus in system. For example on 24 core system, 24 CPT LFs will be attached per VF. That means no CPT LF available when creating more than 2 CPT VFs on system which have total 64 LFs. Although VFs gets created but no LF attached to it. There seems no reason to default allocate as many LFs as many online cpus in system. This patch initializes "kvf_limits" to one to limit one LF allocated per CPT VF. "kvf_limits" can be changed in range of 1 to number-of-online-cpus via sysfs.

2023-12-08crypto: qat - fix error path in add_update_sla()Damian Muszynski
The input argument `sla_in` is a pointer to a structure that contains the parameters of the SLA which is being added or updated. If this pointer is NULL, the function should return an error as the data required for the algorithm is not available. By mistake, the logic jumps to the error path which dereferences the pointer. This results in a warnings reported by the static analyzer Smatch when executed without a database: drivers/crypto/intel/qat/qat_common/adf_rl.c:871 add_update_sla() error: we previously assumed 'sla_in' could be null (see line 812) This issue was not found in internal testing as the pointer cannot be NULL. The function add_update_sla() is only called (indirectly) by the rate limiting sysfs interface implementation in adf_sysfs_rl.c which ensures that the data structure is allocated and valid. This is also proven by the fact that Smatch executed with a database does not report such error. Fix it by returning with error if the pointer `sla_in` is NULL.

If a pointer to an uninitialized struct acpi_handle_list is passed to acpi_evaluate_reference() and it decides to bail out early, either because acpi_evaluate_object() fails, or because it produces invalid data, the handles pointer from the struct acpi_handle_list will be passed to kfree() and if it is not NULL, the kernel will crash on an attempt to free unallocated memory. Address this by moving the "end" label in acpi_evaluate_reference() to the end of the function, which is sufficient, because no cleanup is needed in that case.

New mddev_resume() calls are added to synchronize IO with array reconfiguration, however, this introduces a performance regression while adding it in md_start_sync(): 1) someone sets MD_RECOVERY_NEEDED first; 2) daemon thread grabs reconfig_mutex, then clears MD_RECOVERY_NEEDED and queues a new sync work; 3) daemon thread releases reconfig_mutex; 4) in md_start_sync a) check that there are spares that can be added/removed, then suspend the array; b) remove_and_add_spares may not be called, or called without really add/remove spares; c) resume the array, then set MD_RECOVERY_NEEDED again! Loop between 2 - 4, then mddev_suspend() will be called quite often, for consequence, normal IO will be quite slow. Fix this problem by don't set MD_RECOVERY_NEEDED again in md_start_sync(), hence the loop will be broken.

2023-12-07wifi: mt76: mt7921s: fix workqueue problem causes STA association failWang Zhao
The ieee80211_queue_work function queues work into the mac80211 local->workqueue, which is widely used for mac80211 internal work processes. In the mt76 driver, both the mt76-sido-status and mt76-sdio-net threads enqueue workers to the workqueue with this function. However, in some cases, when two workers are enqueued to the workqueue almost simultaneously, the second worker may not be scheduled immediately and may get stuck for a while. This can cause timing issues. To avoid these timing conflicts caused by worker scheduling, replace the worker with an independent thread.

2023-12-07wifi: mt76: Convert to platform remove callback returning voidUwe Kleine-König
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 the three mt76 drivers from always returning zero in the remove callback to the void returning variant.
