2023-09-20crypto: qat - ignore subsequent state up commandsGiovanni Cabiddu
If the device is already in the up state, a subsequent write of `up` to the sysfs attribute /sys/bus/pci/devices/<BDF>/qat/state brings the device down. Fix this behaviour by ignoring subsequent `up` commands if the device is already in the up state.

2023-09-20crypto: qat - fix state machines cleanup pathsGiovanni Cabiddu
Commit 1bdc85550a2b ("crypto: qat - fix concurrency issue when device state changes") introduced the function adf_dev_down() which wraps the functions adf_dev_stop() and adf_dev_shutdown(). In a subsequent change, the sequence adf_dev_stop() followed by adf_dev_shutdown() was then replaced across the driver with just a call to the function adf_dev_down(). The functions adf_dev_stop() and adf_dev_shutdown() are called in error paths to stop the accelerator and free up resources and can be called even if the counterparts adf_dev_init() and adf_dev_start() did not complete successfully. However, the implementation of adf_dev_down() prevents the stop/shutdown sequence if the device is found already down. For example, if adf_dev_init() fails, the device status is not set as started and therefore a call to adf_dev_down() won't be calling adf_dev_shutdown() to undo what adf_dev_init() did. Do not check if a device is started in adf_dev_down() but do the equivalent check in adf_sysfs.c when handling a DEV_DOWN command from the user.

2023-09-20crypto: qat - refactor deprecated strncpyJustin Stitt
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. `buf` is expected to be NUL-terminated for its eventual use in `kstrtoul()` and NUL-padding is not required. Due to the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer.

2023-09-15hwrng: geode - fix accessing registersJonas Gorski
When the membase and pci_dev pointer were moved to a new struct in priv, the actual membase users were left untouched, and they started reading out arbitrary memory behind the struct instead of registers. This unfortunately turned the RNG into a constant number generator, depending on the content of what was at that offset. To fix this, update geode_rng_data_{read,present}() to also get the membase via amd_geode_priv, and properly read from the right addresses again.

In normal case, aead_request_complete() will be called in pcrypt_aead_serial and the return err is 0 for padata_do_parallel. But, when pinst->flags is PADATA_RESET, the return err is -EBUSY for padata_do_parallel, and it won't call aead_request_complete(). Therefore, test_aead_vec_cfg will hung at wait_for_completion(&wait->completion), which will cause hungtask. The problem comes as following: (padata_do_parallel) | rcu_read_lock_bh(); | err = -EINVAL; | (padata_replace) | pinst->flags |= PADATA_RESET; err = -EBUSY | if (pinst->flags & PADATA_RESET) | rcu_read_unlock_bh() | return err In order to resolve the problem, we replace the return err -EBUSY with -EAGAIN, which means parallel_data is changing, and the caller should call it again. v3: remove retry and just change the return err. v2: introduce padata_try_do_parallel() in pcrypt_aead_encrypt and pcrypt_aead_decrypt to solve the hungtask.
