2020-01-23arm64: dts: agilex/stratix10: fix pmu interrupt numbersDinh Nguyen
commit 210de0e996aee8e360ccc9e173fe7f0a7ed2f695 upstream. Fix up the correct interrupt numbers for the PMU unit on Agilex and Stratix10.

2020-01-23arm64: dts: allwinner: a64: olinuxino: Fix eMMC supply regulatorStefan Mavrodiev
commit 8467ebbf708e5c4574b4eb5f663558fc724945ac upstream. A64-OLinuXino-eMMC uses 1.8V for eMMC supply. This is done via a triple jumper, which sets VCC-PL to either 1.8V or 3.3V. This setting is different for boards with and without eMMC. This is not a big issue for DDR52 mode, however the eMMC will not work in HS200/HS400, since these modes explicitly requires 1.8V.

2020-01-23arm64: dts: allwinner: a64: olinuxino: Fix SDIO supply regulatorStefan Mavrodiev
commit 3d615c2fc2d111b51d2e20516b920138d4ae29a2 upstream. A64-OLinuXino uses DCDC1 (VCC-IO) for MMC1 supply. In commit 916b68cfe4b5 ("arm64: dts: a64-olinuxino: Enable RTL8723BS WiFi") ALDO2 is set, which is VCC-PL. Since DCDC1 is always present, the boards are working without a problem. This patch sets the correct regulator.

2020-01-23ALSA: usb-audio: fix sync-ep altsetting sanity checkJohan Hovold
commit 5d1b71226dc4d44b4b65766fa9d74492f9d4587b upstream. The altsetting sanity check in set_sync_ep_implicit_fb_quirk() was checking for there to be at least one altsetting but then went on to access the second one, which may not exist. This could lead to random slab data being used to initialise the sync endpoint in snd_usb_add_endpoint().

commit 60adcfde92fa40fcb2dbf7cc52f9b096e0cd109a upstream. snd_seq_info_timer_read() reads the information of the timer assigned for each queue, but it's done in a racy way which may lead to UAF as spotted by syzkaller.

commit 057efcf9faea4769cf1020677d93d040db9b23f3 upstream. MIC BIAS Internal1 is broken at the moment because we always enable the internal rbias resistor to the TX2 line (connected to the headset microphone), rather than enabling the resistor connected to TX1. Move the RBIAS code to pm8916_wcd_analog_enable_micbias_int1/2() to fix this.

commit e0beec88397b163c7c4ea6fcfb67e8e07a2671dc upstream. MIC BIAS External1 sets pm8916_wcd_analog_enable_micbias_ext1() as event handler, which ends up in pm8916_wcd_analog_enable_micbias_ext(). But pm8916_wcd_analog_enable_micbias_ext() only handles the POST_PMU event, which is not specified in the event flags for MIC BIAS External1. This means that the code in the event handler is never actually run. Set SND_SOC_DAPM_POST_PMU as the only event for the handler to fix this.

2020-01-23ASoC: stm32: sai: fix possible circular lockingOlivier Moysan
commit a14bf98c045bf119b7e779f186528e38c6428830 upstream. In current driver, locks can be taken as follows: - Register access: take a lock on regmap config and then on clock. - Master clock provider: take a lock on clock and then on regmap config. This can lead to the circular locking summarized below. Remove peripheral clock management through regmap framework, and manage peripheral clock in driver instead. On register access, lock on clock is taken first, which allows to avoid possible locking issue.

2020-01-23ASoC: msm8916-wcd-digital: Reset RX interpolation path after useStephan Gerhold
commit 85578bbd642f65065039b1765ebe1a867d5435b0 upstream. For some reason, attempting to route audio through QDSP6 on MSM8916 causes the RX interpolation path to get "stuck" after playing audio a few times. In this situation, the analog codec part is still working, but the RX path in the digital codec stops working, so you only hear the analog parts powering up. After a reboot everything works again. So far I was not able to reproduce the problem when using lpass-cpu. The downstream kernel driver avoids this by resetting the RX interpolation path after use. In mainline we do something similar for the TX decimator (LPASS_CDC_CLK_TX_RESET_B1_CTL), but the interpolator reset (LPASS_CDC_CLK_RX_RESET_CTL) got lost when the msm8916-wcd driver was split into analog and digital. Fix this problem by adding the reset to msm8916_wcd_digital_enable_interpolator().

Commit d878970f6ce1 ("bus: ti-sysc: Add separate functions for handling clocks") separated handling of optional clocks from the main clocks, but introduced an issue where we do not necessarily allocate a slot for both fck and ick clocks, but still assume fixed slots for enumerating over the clocks. Let's fix the issue by ensuring we always have slots for both fck and ick even if we don't use ick, and don't attempt to enumerate optional clocks if not allocated. In the long run we might want to simplify things a bit by only allocating space only for the optional clocks as we have only few devices with optional clocks.

commit 5e82548e26ef62e257dc2ff37c11acb5eb72728e upstream. On sdm845 devices, during boot we see the following warnings (unless we have added 'pd_ignore_unused' to the kernel command line): hlos1_vote_mmnoc_mmu_tbu_sf_gdsc status stuck at 'on' hlos1_vote_mmnoc_mmu_tbu_hf1_gdsc status stuck at 'on' hlos1_vote_mmnoc_mmu_tbu_hf0_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_tbu2_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_tbu1_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_pcie_tbu_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_audio_tbu_gdsc status stuck at 'on' As the name of these GDSCs suggests, they are "votable" and in downstream DT, they all have the property "qcom,no-status-check-on-disable", which means that we should not poll the status bit when we disable them. Luckily the VOTABLE flag already exists and it does exactly what we need, so let's make use of it to make the warnings disappear.

2020-01-23ARM: dts: meson8: fix the size of the PMU registersMartin Blumenstingl
commit 46c9585ed4af688ff1be6d4e76d7ed2f04de4fba upstream. The PMU registers are at least 0x18 bytes wide. Meson8b already uses a size of 0x18. The structure of the PMU registers on Meson8 and Meson8b is similar but not identical. Meson8 and Meson8b have the following registers in common (starting at AOBUS + 0xe0): #define AO_RTI_PWR_A9_CNTL0 0xe0 (0x38 << 2) #define AO_RTI_PWR_A9_CNTL1 0xe4 (0x39 << 2) #define AO_RTI_GEN_PWR_SLEEP0 0xe8 (0x3a << 2) #define AO_RTI_GEN_PWR_ISO0 0x4c (0x3b << 2) Meson8b additionally has these three registers: #define AO_RTI_GEN_PWR_ACK0 0xf0 (0x3c << 2) #define AO_RTI_PWR_A9_MEM_PD0 0xf4 (0x3d << 2) #define AO_RTI_PWR_A9_MEM_PD1 0xf8 (0x3e << 2) Thus we can assume that the register size of the PMU IP blocks is identical on both SoCs (and Meson8 just contains some reserved registers in that area) because the CEC registers start right after the PMU (AO_RTI_*) registers at AOBUS + 0x100 (0x40 << 2). The upcoming power domain driver will need to read and write the AO_RTI_GEN_PWR_SLEEP0 and AO_RTI_GEN_PWR_ISO0 registers, so the updated size is needed for that driver to work.

2020-01-17ocfs2: call journal flush to mark journal as empty after journal recovery ↵Kai Li
when mount [ Upstream commit 397eac17f86f404f5ba31d8c3e39ec3124b39fd3 ] If journal is dirty when mount, it will be replayed but jbd2 sb log tail cannot be updated to mark a new start because journal->j_flag has already been set with JBD2_ABORT first in journal_init_common. When a new transaction is committed, it will be recored in block 1 first(journal->j_tail is set to 1 in journal_reset). If emergency restart happens again before journal super block is updated unfortunately, the new recorded trans will not be replayed in the next mount. The following steps describe this procedure in detail. 1. mount and touch some files 2. these transactions are committed to journal area but not checkpointed 3. emergency restart 4. mount again and its journals are replayed 5. journal super block's first s_start is 1, but its s_seq is not updated 6. touch a new file and its trans is committed but not checkpointed 7. emergency restart again 8. mount and journal is dirty, but trans committed in 6 will not be replayed. This exception happens easily when this lun is used by only one node. If it is used by multi-nodes, other node will replay its journal and its journal super block will be updated after recovery like what this patch does. ocfs2_recover_node->ocfs2_replay_journal.

[ Upstream commit 2f42e05b942fe2fbfb9bbc6e34e1dd8c3ce4f3a4 ] In some cases we seem to submit two transactions in a row, which causes us to lose track of the first. If we then cancel the request, we may still get an interrupt, which traverses a null ds_run value. So try to avoid starting a new transaction if the ds_run value is set. While this patch avoids the null pointer crash, I've had some reports of the k3dma driver still getting confused, which suggests the ds_run/ds_done value handling still isn't quite right. However, I've not run into an issue recently with it so I think this patch is worth pushing upstream to avoid the crash.

[ Upstream commit 13b7955a0252e15265386b229b814152f109b234 ] Standard kernel mutexes cannot be used in any way from interrupt or softirq context, so the user_mutex which manages access to a call cannot be a mutex since on a new call the mutex must start off locked and be unlocked within the softirq handler to prevent userspace interfering with a call we're setting up. Commit a0855d24fc22d49cdc25664fb224caee16998683 ("locking/mutex: Complain upon mutex API misuse in IRQ contexts") causes big warnings to be splashed in dmesg for each a new call that comes in from the server. Whilst it *seems* like it should be okay, since the accept path uses trylock, there are issues with PI boosting and marking the wrong task as the owner. Fix this by not taking the mutex in the softirq path at all. It's not obvious that there should be any need for it as the state is set before the first notification is generated for the new call. There's also no particular reason why the link-assessing ping should be triggered inside the mutex. It's not actually transmitted there anyway, but rather it has to be deferred to a workqueue. Further, I don't think that there's any particular reason that the socket notification needs to be done from within rx->incoming_lock, so the amount of time that lock is held can be shortened too and the ping prepared before the new call notification is sent.

2020-01-17selftests: firmware: Fix it to do root uid check and skipShuah Khan
[ Upstream commit c65e41538b04e0d64a673828745a00cb68a24371 ] firmware attempts to load test modules that require root access and fail. Fix it to check for root uid and exit with skip code instead. Before this fix: selftests: firmware: fw_run_tests.sh modprobe: ERROR: could not insert 'test_firmware': Operation not permitted You must have the following enabled in your kernel: CONFIG_TEST_FIRMWARE=y CONFIG_FW_LOADER=y CONFIG_FW_LOADER_USER_HELPER=y CONFIG_IKCONFIG=y CONFIG_IKCONFIG_PROC=y not ok 1 selftests: firmware: fw_run_tests.sh # SKIP With this fix: selftests: firmware: fw_run_tests.sh skip all tests: must be run as root not ok 1 selftests: firmware: fw_run_tests.sh # SKIP Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> Reviwed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
2020-01-17scsi: target/iblock: Fix protection error with blocks greater than 512BIsrael Rukshin
[ Upstream commit e4dc9a4c31fe10d1751c542702afc85be8a5c56a ] The sector size of the block layer is 512 bytes, but integrity interval size might be different (in case of 4K block size of the media). At the initiator side the virtual start sector is the one that was originally submitted by the block layer (512 bytes) for the Reftag usage. The initiator converts the Reftag to integrity interval units and sends it to the target. So the target virtual start sector should be calculated at integrity interval units. prepare_fn() and complete_fn() don't remap correctly the Reftag when using incorrect units of the virtual start sector, which leads to the following protection error at the device: "blk_update_request: protection error, dev sdb, sector 2048 op 0x0:(READ) flags 0x10000 phys_seg 1 prio class 0" To fix that, set the seed in integrity interval units.
