2019-08-09ASoC: soc-core: support snd_soc_dai_link_component for aux_devKuninori Morimoto
To find aux_dev, ASoC is using .name, codec_name, codec_of_node. Here, .name is used to fallback in case of no codec. But, we already have this kind of component finding method by snd_soc_dai_link_component and soc_find_component(). We shouldn't have duplicated implementation to do same things. This patch adds snd_soc_dai_link_component support to finding aux_dev. Now, no driver is using only .name. All drivers are using codec_name and/or codec_of_node. This means no driver is finding component from .name so far. (Actually almost all drivers are using .name as just "device name", not for finding component...) This patch 1) add snd_soc_dai_link_component support for aux_dev. legacy style will be removed if all drivers are switched to new style. 2) try to find component via snd_soc_dai_link_component. Then, it doesn't try to find via .name, because no driver is using it so far.

2019-08-09ASoC: hdac_hdmi: Offload dapm update at jack detectionTakashi Iwai
hdac_hdmi_present_sense() calls the audio component to get ELD update, then it reports the jack status change and updates DAPM graph accordingly. This works when it's called from the normal code paths. However, it may lead to a dead lock when it's called from the audio component notifier. Namely, the DAPM update involves with the runtime PM, and it eventually calls again the audio component get_power() ops. Since i915 driver already takes a mutex around the audio component ops calls, we'll eventually get the mutex doubly. As a workaround, in this patch, only the jack state is updated in the code path from hdac_hdmi_eld_notify_cb(), and the DAPM update is deferred to a work so that it's processed in another context.

2019-08-10kbuild: show hint if subdir-y/m is used to visit module MakefileMasahiro Yamada
Since commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod"), a module is no longer built in the following pattern: [Makefile] subdir-y := some-module [some-module/Makefile] obj-m := some-module.o You cannot write Makefile this way in upstream because modules.order is not correctly generated. subdir-y is used to descend to a sub-directory that builds tools, device trees, etc. For external modules, the modules order does not matter. So, the Makefile above was known to work. I believe the Makefile should be re-written as follows: [Makefile] obj-m := some-module/ [some-module/Makefile] obj-m := some-module.o However, people will have no idea if their Makefile suddenly stops working. In fact, I received questions from multiple people. Show a warning for a while if obj-m is specified in a Makefile visited by subdir-y or subdir-m. I touched the %/ rule to avoid false-positive warnings for the single target.

2019-08-10kbuild: generate modules.order only in directories visited by obj-y/mMasahiro Yamada
The modules.order files in directories visited by the chain of obj-y or obj-m are merged to the upper-level ones, and become parts of the top-level modules.order. On the other hand, there is no need to generate modules.order in directories visited by subdir-y or subdir-m since they would become orphan anyway.

2019-08-10kbuild: fix false-positive need-builtin calculationMasahiro Yamada

2019-08-10kbuild: revive single target %.koMasahiro Yamada
I removed the single target %.ko in commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod") because the modpost stage does not work reliably. For instance, the module dependency, modversion, etc. do not work if we lack symbol information from the other modules. Yet, some people still want to build only one module in their interest, and it may be still useful if it is used within those limitations.

It turns out that the current version of gfs2_metadata_walker suffers from multiple problems that can cause gfs2_hole_size to report an incorrect size. This will confuse fiemap as well as lseek with the SEEK_DATA flag.

2019-08-09iommu/dma: Handle SG length overflow betterRobin Murphy
Since scatterlist dimensions are all unsigned ints, in the relatively rare cases where a device's max_segment_size is set to UINT_MAX, then the "cur_len + s_length <= max_len" check in __finalise_sg() will always return true. As a result, the corner case of such a device mapping an excessively large scatterlist which is mergeable to or beyond a total length of 4GB can lead to overflow and a bogus truncated dma_length in the resulting segment. As we already assume that any single segment must be no longer than max_len to begin with, this can easily be addressed by reshuffling the comparison.

The object lifetime management on the rxrpc_local struct is broken in that the rxrpc_local_processor() function is expected to clean up and remove an object - but it may get requeued by packets coming in on the backing UDP socket once it starts running. This may result in the assertion in rxrpc_local_rcu() firing because the memory has been scheduled for RCU destruction whilst still queued: rxrpc: Assertion failed ------------[ cut here ]------------ kernel BUG at net/rxrpc/local_object.c:468! Note that if the processor comes around before the RCU free function, it will just do nothing because ->dead is true. Fix this by adding a separate refcount to count active users of the endpoint that causes the endpoint to be destroyed when it reaches 0. The original refcount can then be used to refcount objects through the work processor and cause the memory to be rcu freed when that reaches 0.

2019-08-09netfilter: nf_flow_table: teardown flow timeout racePablo Neira Ayuso
Flows that are in teardown state (due to RST / FIN TCP packet) still have their offload flag set on. Hence, the conntrack garbage collector may race to undo the timeout adjustment that the fixup routine performs, leaving the conntrack entry in place with the internal offload timeout (one day). Update teardown flow state to ESTABLISHED and set tracking to liberal, then once the offload bit is cleared, adjust timeout if it is more than the default fixup timeout (conntrack might already have set a lower timeout from the packet path).

Update conntrack entry to pick up expired flows, otherwise the conntrack entry gets stuck with the internal offload timeout (one day).

2019-08-09netfilter: nf_tables: use-after-free in failing rule with bound setPablo Neira Ayuso
If a rule that has already a bound anonymous set fails to be added, the preparation phase releases the rule and the bound set. However, the transaction object from the abort path still has a reference to the set object that is stale, leading to a use-after-free when checking for the set->bound field. Add a new field to the transaction that specifies if the set is bound, so the abort path can skip releasing it since the rule command owns it and it takes care of releasing it. After this update, the set->bound field is removed.

2019-08-09ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creationDaniel Baluta
There is a lot of duplicate code when processing IPC firmware ready notification and creating memory windows. First step in reducing the code duplication is to introduce generic functions: * sof_get_windows * sof_fw_ready that will replace, in the first step, the specific implementation related to baytrail related platforms: * byt_get_windows * byt_fw_ready So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value. Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.

This is reserved for some historical reason, we didn't enable memory windows for byt/bdw at the beginning, to make it compatible, we get those mailbox offsets from fw_ready struct firstly, and then update them if they existed in the following memory windows, to make sure the mailbox still can be used if no memory windows are created. With this change all platforms have the same implementation for xxx_fw_ready function so that we can refactor it in a common file.

2019-08-09omap-dma/omap_vout_vrfb: fix off-by-one fi valueHans Verkuil
The OMAP 4 TRM specifies that when using double-index addressing the address increases by the ES plus the EI value minus 1 within a frame. When a full frame is transferred, the address increases by the ES plus the frame index (FI) value minus 1. The omap-dma code didn't account for the 'minus 1' in the FI register. To get correct addressing, add 1 to the src_icg value. This was found when testing a hacked version of the media m2m-deinterlace.c driver on a Pandaboard. The only other source that uses this feature is omap_vout_vrfb.c, and that adds a + 1 when setting the dst_icg. This is a workaround for the broken omap-dma.c behavior. So remove the workaround at the same time that we fix omap-dma.c. I tested the omap_vout driver with a Beagle XM board to check that the '+ 1' in omap_vout_vrfb.c was indeed a workaround for the omap-dma bug.

s390 does not map the vdso for statically linked binaries, assuming that this doesn't make sense. See commit fc5243d98ac2 ("[S390] arch_setup_additional_pages arguments"). However with glibc commit d665367f596d ("linux: Enable vDSO for static linking as default (BZ#19767)") and commit 5e855c895401 ("s390: Enable VDSO for static linking") the vdso is also used for statically linked binaries - if the kernel would make it available. Therefore map the vdso always, just like all other architectures.
