2022-09-30ALSA: usb-audio: Fix potential memory leaksTakashi Iwai
When the driver hits -ENOMEM at allocating a URB or a buffer, it aborts and goes to the error path that releases the all previously allocated resources. However, when -ENOMEM hits at the middle of the sync EP URB allocation loop, the partially allocated URBs might be left without released, because ep->nurbs is still zero at that point. Fix it by setting ep->nurbs at first, so that the error handler loops over the full URB list.

2022-09-30ALSA: usb-audio: Fix NULL dererence at error pathTakashi Iwai
At an error path to release URB buffers and contexts, the driver might hit a NULL dererence for u->urb pointer, when u->buffer_size has been already set but the actual URB allocation failed. Fix it by adding the NULL check of urb. Also, make sure that buffer_size is cleared after the error path or the close. Cc: <stable@vger.kernel.org> Reported-by: Sabri N.

2022-09-30ASoC: mediatek: mt8192-mt6359: Set the driver name for the cardNícolas F. R. A. Prado
The ASoC core automatically populates the driver name field in the card from the card name if left unset. However, since the driver name can be at most 16 characters long, wrapping will happen if the card name is longer, which is the case for the mt8192-mt6359 driver. Explicitly set the driver name for the card in order to avoid said wrapping and have a readable driver name exposed to userspace. Signed-off-by: Nícolas F. R. A.

2022-09-30ALSA: hda/realtek: More robust component matching for CS35L41Takashi Iwai
As the previous commit implies, a system may have a different SPI bus number that is embedded in the device string. And, assuming the fixed bus number is rather fragile; it may be assigned differently depending on the configuration or on the boot environment. Once when a bus number change happens, the binding fails, resulting in the silence. This patch tries to make the matching a bit more relaxed, allowing to bind with a different bus number (or without it). So the previous fix, the introduction of ALC245_FIXUP_CS35L41_SPI1_2 fixup became superfluous, and this is unified to ALC245_FIXUP_CS35L41_SPI_2.

2022-09-30powerpc/mm: Fix UBSAN warning reported on hugetlbAneesh Kumar K.V
Powerpc architecture supports 16GB hugetlb pages with hash translation. For 4K page size, this is implemented as a hugepage directory entry at PGD level and for 64K it is implemented as a huge page pte at PUD level With 16GB hugetlb size, offset within a page is greater than 32 bits. Hence switch to use unsigned long type when using hugepd_shift. In order to keep things simpler, we make sure we always use unsigned long type when using hugepd_shift() even though all the hugetlb page size won't require that. The hugetlb_free_p*d_range changes are all related to nohash usage where we can have multiple pgd entries pointing to the same hugepd entries. Hence on book3s64 where we can have > 4GB hugetlb page size we will always find more < next even if we compute the value of more correctly. Hence there is no functional change in this patch except that it fixes the below warning.

2022-09-30powerpc/pseries/vas: Pass hw_cpu_id to node associativity HCALLHaren Myneni
Generally the hypervisor decides to allocate a window on different VAS instances. But if user space wishes to allocate on the current VAS instance where the process is executing, the kernel has to pass associativity domain IDs to allocate VAS window HCALL. To determine the associativity domain IDs for the current CPU, smp_processor_id() is passed to node associativity HCALL which may return H_P2 (-55) error during DLPAR CPU event. This is because Linux CPU numbers (smp_processor_id()) are not the same as the hypervisor's view of CPU numbers. Fix the issue by passing hard_smp_processor_id() with VPHN_FLAG_VCPU flag (PAPR 14.11.6.1 H_HOME_NODE_ASSOCIATIVITY).

Single-step slot would not be used until kprobe is enabled, that means no race condition occurs on it under SMP, hence it is safe to pacth ss slot without stopping machine.

2022-09-30Fix PM disable depth imbalance in probeMark Brown
Merge series from Zhang Qilong <zhangqilong3@huawei.com>: The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by moving pm_runtime_enable to the endding of probe.

2022-09-29hardening: Remove Clang's enable flag for -ftrivial-auto-var-init=zeroKees Cook
Now that Clang's -enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang option is no longer required, remove it from the command line. Clang 16 and later will warn when it is used, which will cause Kconfig to think it can't use -ftrivial-auto-var-init=zero at all. Check for whether it is required and only use it when so.

2022-09-30hwrng: core - start hwrng kthread also for untrusted sourcesDominik Brodowski
Start the hwrng kthread even if the hwrng source has a quality setting of zero. Then, every crng reseed interval, one batch of data from this zero-quality hwrng source will be mixed into the CRNG pool. This patch is based on the assumption that data from a hwrng source will not actively harm the CRNG state. Instead, many hwrng sources (such as TPM devices), even though they are assigend a quality level of zero, actually provide some entropy, which is good enough to mix into the CRNG pool every once in a while.
