2019-05-28ASoC: SOF: ipc: fix a race, leading to IPC timeoutsGuennadi Liakhovetski
Currently on all supported platforms the IPC IRQ thread first signals the sender when an IPC response is received from the DSP, then unmasks the IPC interrupt. Those actions are performed without holding any locks, so the thread can be interrupted between them. IPC timeouts have been observed in such scenarios: if the sender is woken up and it proceeds with sending the next message without unmasking the IPC interrupt, it can miss the next response. This patch takes a spin-lock to prevent the IRQ thread from being preempted at that point. It also makes sure, that the next IPC transmission by the host cannot take place before the IRQ thread has finished updating all the required IPC registers.

2019-05-28ASoC: SOF: pcm: clear hw_params_upon_resume flag correctlyLibin Yang
sof_pcm_hw_params() can only be called once to setup the FW hw_params. So after calling sof_pcm_hw_params(), hw_params_upon_resume flag must be cleared to avoid multiple invoking sof_pcm_hw_params() by prepare. For example, after resume, there is an xrun happened, prepare() will be called. As the hw_params_upon_resume flag is not cleared, sof_pcm_hw_params() will be called and this will cause IPC timeout.

2019-05-28ASoC: SOF: core: fix error handling with the probe workqueuePierre-Louis Bossart
In some configurations, it's a requirement to split the probe in two, with a second part handled in a workqueue (e.g. for HDMI support which depends on the DRM modules). SOF already handles these configurations but the error flow is incorrect. When an error occurs in the workqueue, the probe has technically already completed. If we release the resources on errors, this generates kernel oops/use-after-free when the resources are released a second time on module removal.

2019-05-28ASoC: SOF: core: remove DSP after unregistering machine driverRanjani Sridharan
snd_sof_remove() disables the DSP and unmaps the DSP BAR. Removing topology after disabling the DSP results in a kernel panic while unloading the pipeline widget. This is because pipeline widget unload attempts to power down the core it is scheduled on by accessing the DSP registers. So, the suggested fix here is to unregister the machine driver first to remove the topology and then disable the DSP to avoid the situation described above. Note that the kernel panic only happens in cases where the HDaudio link is not managed by the hdac library, e.g. no codec or when HDMI is not supported. When the hdac library is used, snd_sof_remove() calls snd_hdac_ext_bus_device_remove() to remove the codec which unregisters the component driver thereby also removing the topology before the DSP is disabled.

2019-05-28arm64/module: revert to unsigned interpretation of ABS16/32 relocationsArd Biesheuvel
Commit 1cf24a2cc3fd ("arm64/module: deal with ambiguity in PRELxx relocation ranges") updated the overflow checking logic in the relocation handling code to ensure that PREL16/32 relocations don't overflow signed quantities. However, the same code path is used for absolute relocations, where the interpretation is the opposite: the only current use case for absolute relocations operating on non-native word size quantities is the CRC32 handling in the CONFIG_MODVERSIONS code, and these CRCs are unsigned 32-bit quantities, which are now being rejected by the module loader if bit 31 happens to be set. So let's use different ranges for quanties subject to absolute vs. relative relocations: - ABS16/32 relocations should be in the range [0, Uxx_MAX) - PREL16/32 relocations should be in the range [Sxx_MIN, Sxx_MAX) - otherwise, print an error since no other 16 or 32 bit wide data relocations are currently supported.

2019-05-28KVM: s390: Do not report unusabled IDs via KVM_CAP_MAX_VCPU_IDThomas Huth
KVM_CAP_MAX_VCPU_ID is currently always reporting KVM_MAX_VCPU_ID on all architectures. However, on s390x, the amount of usable CPUs is determined during runtime - it is depending on the features of the machine the code is running on. Since we are using the vcpu_id as an index into the SCA structures that are defined by the hardware (see e.g. the sca_add_vcpu() function), it is not only the amount of CPUs that is limited by the hard- ware, but also the range of IDs that we can use. Thus KVM_CAP_MAX_VCPU_ID must be determined during runtime on s390x, too. So the handling of KVM_CAP_MAX_VCPU_ID has to be moved from the common code into the architecture specific code, and on s390x we have to return the same value here as for KVM_CAP_MAX_VCPUS. This problem has been discovered with the kvm_create_max_vcpus selftest. With this change applied, the selftest now passes on s390x, too.

2019-05-28xprtrdma: Use struct_size() in kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

2019-05-28perf record: Fix s390 missing module symbol and warning for non-root usersThomas Richter
Command 'perf record' and 'perf report' on a system without kernel debuginfo packages uses /proc/kallsyms and /proc/modules to find addresses for kernel and module symbols. On x86 this works for root and non-root users. On s390, when invoked as non-root user, many of the following warnings are shown and module symbols are missing: proc/{kallsyms,modules} inconsistency while looking for "[sha1_s390]" module! Command 'perf record' creates a list of module start addresses by parsing the output of /proc/modules and creates a PERF_RECORD_MMAP record for the kernel and each module. The following function call sequence is executed: machine__create_kernel_maps machine__create_module modules__parse machine__create_module --> for each line in /proc/modules arch__fix_module_text_start Function arch__fix_module_text_start() is s390 specific. It opens file /sys/module/<name>/sections/.text to extract the module's .text section start address. On s390 the module loader prepends a header before the first section, whereas on x86 the module's text section address is identical the the module's load address. However module section files are root readable only. For non-root the read operation fails and machine__create_module() returns an error. Command perf record does not generate any PERF_RECORD_MMAP record for loaded modules. Later command perf report complains about missing module maps. To fix this function arch__fix_module_text_start() always returns success. For root users there is no change, for non-root users the module's load address is used as module's text start address (the prepended header then counts as part of the text section). This enable non-root users to use module symbols and avoid the warning when perf report is executed.

2019-05-28s390/crypto: fix gcm-aes-s390 selftest failuresHarald Freudenberger
The current kernel uses improved crypto selftests. These tests showed that the current implementation of gcm-aes-s390 is not able to deal with chunks of output buffers which are not a multiple of 16 bytes. This patch introduces a rework of the gcm aes s390 scatter walk handling which now is able to handle any input and output scatter list chunk sizes correctly. Code has been verified by the crypto selftests, the tcrypt kernel module and additional tests ran via the af_alg interface.

2019-05-28s390/zcrypt: Fix wrong dispatching for control domain CPRBsHarald Freudenberger
The zcrypt device driver does not handle CPRBs which address a control domain correctly. This fix introduces a workaround: The domain field of the request CPRB is checked if there is a valid domain value in there. If this is true and the value is a control only domain (a domain which is enabled in the crypto config ADM mask but disabled in the AQM mask) the CPRB is forwarded to the default usage domain. If there is no default domain, the request is rejected with an ENODEV. This fix is important for maintaining crypto adapters. For example one LPAR can use a crypto adapter domain ('Control and Usage') but another LPAR needs to be able to maintain this adapter domain ('Control'). Scenarios like this did not work properly and the patch enables this. Signed-off-by: Harald Freudenberger <freude@linux.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

Of course, we could mark get_fault_type() as __always_inline to get back the original behavior, but I do not think it sensible to force inlining just for the purpose of suppressing the warning. Since this is just a matter of warning, I want to keep as much room for compiler optimization as possible. I added unreachable() to teach the compiler that the 'default' label is unreachable. I got rid of the 'inline' marker. Even without the 'inline' hint, the compiler inlines functions based on its inlining heuristic.

We need to let ti-sysc driver manage clockdomain autoidle for the duration of of reset, enable and idle. And we need to do it before we enable the clock and after we disable it. Currently we are still relying on platform callbacks indirectly managing clockdomain autoidle. But I noticed that for device tree only probed drivers it now happens only after we enabling the clocks and before we disable the clocks, while it should be the other way around. So far I have not noticed any issues with this though. Let's add new ti_sysc_clkdm_deny_idle() and ti_sysc_clkdm_allow_idle() functions for ti-sysc driver to use to manage clockdomains directly via platform data callbacks. Note that we can implement the clockdomain functions in pdata-quirks.c as for probing devices without "ti,hwmods" custom property we don't need to use the other platform data callbacks. Let's do this in one patch as there's is still an unlikely chance we may need to apply this as a fix for v5.2 for dropping legacy platform data for some devices. We also do have the option of adding back the platform data if needed in case of trouble. Tested-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
