2021-11-18power: supply: max17042_battery: Prevent int underflow in set_soc_thresholdSebastian Krzyszkowiak1-1/+2
commit e660dbb68c6b3f7b9eb8b9775846a44f9798b719 upstream. max17042_set_soc_threshold gets called with offset set to 1, which means that minimum threshold value would underflow once SOC got down to 0, causing invalid alerts from the gauge.

2021-11-18mtd: rawnand: socrates: Keep the driver compatible with on-die ECC enginesMiquel Raynal1-3/+9
commit b4ebddd6540d78a7f977b3fea0261bd575c6ffe2 upstream. Following the introduction of the generic ECC engine infrastructure, it was necessary to reorganize the code and move the ECC configuration in the ->attach_chip() hook. Failing to do that properly lead to a first series of fixes supposed to stabilize the situation. Unfortunately, this only fixed the use of software ECC engines, preventing any other kind of engine to be used, including on-die ones. It is now time to (finally) fix the situation by ensuring that we still provide a default (eg. software ECC) but will still support different ECC engines such as on-die ECC engines if properly described in the device tree. There are no changes needed on the core side in order to do this, but we just need to leverage the logic there which allows: 1- a subsystem default (set to Host engines in the raw NAND world) 2- a driver specific default (here set to software ECC engines) 3- any type of engine requested by the user (ie. described in the DT) As the raw NAND subsystem has not yet been fully converted to the ECC engine infrastructure, in order to provide a default ECC engine for this driver we need to set chip->ecc.engine_type *before* calling nand_scan(). During the initialization step, the core will consider this entry as the default engine for this driver. This value may of course be overloaded by the user if the usual DT properties are provided.

2021-11-18memory: renesas-rpc-if: Correct QSPI data transfer in Manual modeWolfram Sang1-35/+78
commit fff53a551db50f5edecaa0b29a64056ab8d2bbca upstream. This patch fixes 2 problems: [1] The output warning logs and data loss when performing mount/umount then remount the device with jffs2 format. [2] The access width of SMWDR[0:1]/SMRDR[0:1] register is wrong. This is the sample warning logs when performing mount/umount then remount the device with jffs2 format: jffs2: jffs2_scan_inode_node(): CRC failed on node at 0x031c51d4: Read 0x00034e00, calculated 0xadb272a7 The reason for issue [1] is that the writing data seems to get messed up. Data is only completed when the number of bytes is divisible by 4. If you only have 3 bytes of data left to write, 1 garbage byte is inserted after the end of the write stream. If you only have 2 bytes of data left to write, 2 bytes of '00' are added into the write stream. If you only have 1 byte of data left to write, 2 bytes of '00' are added into the write stream. 1 garbage byte is inserted after the end of the write stream. To solve problem [1], data must be written continuously in serial and the write stream ends when data is out. Following HW manual 62.2.15, access to SMWDR0 register should be in the same size as the transfer size specified in the SPIDE[3:0] bits in the manual mode enable setting register (SMENR). Be sure to access from address 0. So, in 16-bit transfer (SPIDE[3:0]=b'1100), SMWDR0 should be accessed by 16-bit width. Similar to SMWDR1, SMDDR0/1 registers. In current code, SMWDR0 register is accessed by regmap_write() that only set up to do 32-bit width. To solve problem [2], data must be written 16-bit or 8-bit when transferring 1-byte or 2-byte.

2021-11-18rsi: Fix module dev_oper_mode parameter descriptionMarek Vasut3-8/+13
commit 31f97cf9f0c31143a2a6fcc89c4a1286ce20157e upstream. The module parameters are missing dev_oper_mode 12, BT classic alone, add it. Moreover, the parameters encode newlines, which ends up being printed malformed e.g. by modinfo, so fix that too. However, the module parameter string is duplicated in both USB and SDIO modules and the dev_oper_mode mode enumeration in those module parameters is a duplicate of macros used by the driver. Furthermore, the enumeration is confusing. So, deduplicate the module parameter string and use __stringify() to encode the correct mode enumeration values into the module parameter string. Finally, replace 'Wi-Fi' with 'Wi-Fi alone' and 'BT' with 'BT classic alone' to clarify what those modes really mean.

2021-11-18rsi: fix rate mask set leading to P2P failureMartin Fuzzey4-65/+50
commit b515d097053a71d624e0c5840b42cd4caa653941 upstream. P2P client mode was only working the first time. On subsequent connection attempts the group was successfully created but no data was sent (no transmitted data packets were seen with a sniffer). The reason for this was that the hardware was being configured in fixed rate mode with rate RSI_RATE_1 (1Mbps) which is not valid in the 5GHz band. In P2P mode wpa_supplicant uses NL80211_CMD_SET_TX_BITRATE_MASK to disallow the 11b rates in the 2.4GHz band which updated common->fixedrate_mask. rsi_set_min_rate() then used the fixedrate_mask to calculate the minimum allowed rate, or 0xffff = auto if none was found. However that calculation did not account for the different rate sets allowed in the different bands leading to the error. Fixing set_min_rate() would result in 6Mb/s being used all the time which is not what we want either. The reason the problem did not occur on the first connection is that rsi_mac80211_set_rate_mask() only updated the fixedrate_mask for the *current* band. When it was called that was still 2.4GHz as the switch is done later. So the when set_min_rate() was subsequently called after the switch to 5GHz it still had a mask of zero, leading to defaulting to auto mode. Fix this by differentiating the case of a single rate being requested, in which case the hardware will be used in fixed rate mode with just that rate, and multiple rates being requested, in which case we remain in auto mode but the firmware rate selection algorithm is configured with a restricted set of rates.

2021-11-18rsi: fix key enabled check causing unwanted encryption for vap_id > 0Martin Fuzzey3-1/+4
commit 99ac6018821253ec67f466086afb63fc18ea48e2 upstream. My previous patch checked if encryption should be enabled by directly checking info->control.hw_key (like the downstream driver). However that missed that the control and driver_info members of struct ieee80211_tx_info are union fields. Due to this when rsi_core_xmit() updates fields in "tx_params" (driver_info) it can overwrite the control.hw_key, causing the result of the later test to be incorrect. With the current structure layout the first byte of control.hw_key is overlayed with the vap_id so, since we only test if control.hw_key is NULL / non NULL, a non zero vap_id will incorrectly enable encryption. In basic STA and AP modes the vap_id is always zero so it works but in P2P client mode a second VIF is created causing vap_id to be non zero and hence encryption to be enabled before keys have been set. Fix this by extracting the key presence flag to a new field in the driver private tx_params structure and populating it first.

2021-11-18rsi: fix occasional initialisation failure with BT coexMartin Fuzzey3-3/+18
commit 9b14ed6e11b72dd4806535449ca6c6962cb2369d upstream. When BT coexistence is enabled (eg oper mode 13, which is the default) the initialisation on startup sometimes silently fails. In a normal initialisation we see usb 1-1.3: Product: Wireless USB Network Module usb 1-1.3: Manufacturer: Redpine Signals, Inc. usb 1-1.3: SerialNumber: 000000000001 rsi_91x: rsi_probe: Initialized os intf ops rsi_91x: rsi_load_9116_firmware: Loading chunk 0 rsi_91x: rsi_load_9116_firmware: Loading chunk 1 rsi_91x: rsi_load_9116_firmware: Loading chunk 2 rsi_91x: Max Stations Allowed = 1 But sometimes the last log is missing and the wlan net device is not created. Running a userspace loop that resets the hardware via a GPIO shows the problem occurring ~5/100 resets. The problem does not occur in oper mode 1 (wifi only). Adding logs shows that the initialisation state machine requests a MAC reset via rsi_send_reset_mac() but the firmware does not reply, leading to the initialisation sequence being incomplete. Fix this by delaying attaching the BT adapter until the wifi initialisation has completed. With this applied I have done > 300 reset loops with no errors.

commit 6b51b02a3a0ac49dfe302818d0746a799545e4e9 upstream. Daniel pointed me towards this function and there are multiple obvious problems in the implementation. First of all the retry loop is not working as intended. In general the retry makes only sense if you grab the reference first and then check the sequence values. Then we should always also wait for the exclusive fence. It's also good practice to keep the reference around when installing callbacks to fences you don't own. And last the whole implementation was unnecessary complex and rather hard to understand which could lead to probably unexpected behavior of the IOCTL. Fix all this by reworking the implementation from scratch. Dropping the whole RCU approach and taking the lock instead. Only mildly tested and needs a thoughtful review of the code. Pushing through drm-misc-next to avoid merge conflicts and give the code another round of testing. v2: fix the reference counting as well v3: keep the excl fence handling as is for stable v4: back to testing all fences, drop RCU v5: handle in and out separately v6: add missing clear of events v7: change coding style as suggested by Michel, drop unused variables Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Tested-by: Michel Dänzer <mdaenzer@redhat.com> CC: stable@vger.kernel.org Link: https://patchwork.freedesktop.org/patch/msgid/20210720131110.88512-1-christian.koenig@amd.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit f971a85439bd25dc7b4d597cf5e4e8dc7ffc884b upstream. Checking if DMA is enabled should be done via the ata_dma_enabled helper function, since the init state 0xff indicates disabled. This meant that ATA_CMD_READ_LOG_DMA_EXT was used and probed for before DMA was enabled, which caused hangs for some combinations of controllers and devices. It might also have caused it to be incorrectly disabled as broken, but there have been no reports of that.

2021-11-18mwifiex: Try waking the firmware until we get an interruptJonas Dreßler1-5/+23
commit 8e3e59c31fea5de95ffc52c46f0c562c39f20c59 upstream. It seems that the PCIe+USB firmware (latest version 15.68.19.p21) of the 88W8897 card sometimes ignores or misses when we try to wake it up by writing to the firmware status register. This leads to the firmware wakeup timeout expiring and the driver resetting the card because we assume the firmware has hung up or crashed. Turns out that the firmware actually didn't hang up, but simply "missed" our wakeup request and didn't send us an interrupt with an AWAKE event. Trying again to read the firmware status register after a short timeout usually makes the firmware wake up as expected, so add a small retry loop to mwifiex_pm_wakeup_card() that looks at the interrupt status to check whether the card woke up. The number of tries and timeout lengths for this were determined experimentally: The firmware usually takes about 500 us to wake up after we attempt to read the status register. In some cases where the firmware is very busy (for example while doing a bluetooth scan) it might even miss our requests for multiple milliseconds, which is why after 15 tries the waiting time gets increased to 10 ms. The maximum number of tries it took to wake the firmware when testing this was around 20, so a maximum number of 50 tries should give us plenty of safety margin. Here's a reproducer for those firmware wakeup failures I've found: 1) Make sure wifi powersaving is enabled (iw dev wlp1s0 set power_save on) 2) Connect to any wifi network (makes firmware go into wifi powersaving mode, not deep sleep) 3) Make sure bluetooth is turned off (to ensure the firmware actually enters powersave mode and doesn't keep the radio active doing bluetooth stuff) 4) To confirm that wifi powersaving is entered ping a device on the LAN, pings should be a few ms higher than without powersaving 5) Run "while true; do iwconfig; sleep 0.0001; done", this wakes and suspends the firmware extremely often 6) Wait until things explode, for me it consistently takes <5 minutes BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=109681 Cc: stable@vger.kernel.org Signed-off-by: Jonas Dreßler <verdre@v0yd.nl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20211011133224.15561-3-verdre@v0yd.nl Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-11-18mwifiex: Read a PCI register after writing the TX ring write pointerJonas Dreßler1-0/+8
commit e5f4eb8223aa740237cd463246a7debcddf4eda1 upstream. On the 88W8897 PCIe+USB card the firmware randomly crashes after setting the TX ring write pointer. The issue is present in the latest firmware version 15.68.19.p21 of the PCIe+USB card. Those firmware crashes can be worked around by reading any PCI register of the card after setting that register, so read the PCI_VENDOR_ID register here. The reason this works is probably because we keep the bus from entering an ASPM state for a bit longer, because that's what causes the cards firmware to crash. This fixes a bug where during RX/TX traffic and with ASPM L1 substates enabled (the specific substates where the issue happens appear to be platform dependent), the firmware crashes and eventually a command timeout appears in the logs.

2021-11-18wcn36xx: Fix (QoS) null data frame bitrate/modulationLoic Poulain1-0/+1
commit d3fd2c95c1c13ec217d43ebef3c61cfa00a6cd37 upstream. We observe unexpected connection drops with some APs due to non-acked mac80211 generated null data frames (keep-alive). After debugging and capture, we noticed that null frames are submitted at standard data bitrate and that the given APs are in trouble with that. After setting the null frame bitrate to control bitrate, all null frames are acked as expected and connection is maintained. Not sure if it's a requirement of the specification, but it seems the right thing to do anyway, null frames are mostly used for control purpose (power-saving, keep-alive...), and submitting them with a slower/simpler bitrate/modulation is more robust.

commit a9e79b116cc4d0057e912be8f40b2c2e5bdc7c43 upstream. This change fix the TX ack mechanism in various ways: - For NO_ACK tagged packets, we don't need to wait for TX_ACK indication and so are not subject to the single packet ack limitation. So we don't have to stop the tx queue, and can call the tx status callback as soon as DMA transfer has completed. - Fix skb ownership/reference. Only start status indication timeout once the DMA transfer has been completed. This avoids the skb to be both referenced in the DMA tx ring and by the tx_ack_skb pointer, preventing any use-after-free or double-free. - This adds a sanity (paranoia?) check on the skb tx ack pointer. - Resume TX queue if TX status tagged packet TX fails.

commit dc0fd0acb6e0e8025a0a43ada54513b216254fac upstream. Until now, we have only ever seen the REG-category registry being used on devices addressed with target ID 2. In fact, we have only ever seen Surface Aggregator Module (SAM) HID devices with target ID 2. For those devices, the registry also has to be addressed with target ID 2. Some devices, like the new Surface Laptop Studio, however, address their HID devices on target ID 1. As a result of this, any target ID 2 commands time out. This includes event management commands addressed to the target ID 2 REG-category registry. For these devices, the registry has to be addressed via target ID 1 instead. We therefore assume that the target ID of the registry to be used depends on the target ID of the respective device. Implement this accordingly. Note that we currently allow the surface HID driver to only load against devices with target ID 2, so these timeouts are not happening (yet). This is just a preparation step before we allow the driver to load against all target IDs.

2021-11-18regulator: s5m8767: do not use reset value as DVS voltage if GPIO DVS is ↵Krzysztof Kozlowski1-12/+9
disabled commit b16bef60a9112b1e6daf3afd16484eb06e7ce792 upstream. The driver and its bindings, before commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") were requiring to provide at least one safe/default voltage for DVS registers if DVS GPIO is not being enabled. IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.

The IR receiver has two issues: - Sometimes there is no response to a button press - Sometimes a button press is repeated when it should not have been Hanging the polling interval fixes this behaviour.

2021-11-18media: rkvdec: Support dynamic resolution changesChen-Yu Tsai1-20/+20
commit 0887e9e152efbd3601d6c907e90033d25067277d upstream. The mem-to-mem stateless decoder API specifies support for dynamic resolution changes. In particular, the decoder should accept format changes on the OUTPUT queue even when buffers have been allocated, as long as it is not streaming. Relax restrictions for S_FMT as described in the previous paragraph, and as long as the codec format remains the same. This aligns it with the Hantro and Cedrus decoders. This change was mostly based on commit ae02d49493b5 ("media: hantro: Fix s_fmt for dynamic resolution changes"). Since rkvdec_s_fmt() is now just a wrapper around the output/capture variants without any additional shared functionality, drop the wrapper and call the respective functions directly.

2021-11-18media: rkvdec: Do not override sizeimage for output formatChen-Yu Tsai1-2/+3
commit 298d8e8f7bcf023aceb60232d59b983255fec0df upstream. The rkvdec H.264 decoder currently overrides sizeimage for the output format. This causes issues when userspace requires and requests a larger buffer, but ends up with one of insufficient size. Instead, only provide a default size if none was requested. This fixes the video_decode_accelerator_tests from Chromium failing on the first frame due to insufficient buffer space. It also aligns the behavior of the rkvdec driver with the Hantro and Cedrus drivers.

2021-11-18mmc: dw_mmc: Dont wait for DRTO on Write RSP errorChristian Löhle1-1/+2
commit 43592c8736e84025d7a45e61a46c3fa40536a364 upstream. Only wait for DRTO on reads, otherwise the driver hangs. The driver prevents sending CMD12 on response errors like CRCs. According to the comment this is because some cards have problems with this during the UHS tuning sequence. Unfortunately this workaround currently also applies for any command with data. On reads this will set the drto timer, which then triggers after a while. On writes this will not set any timer and the tasklet will not be scheduled again. I cannot test for the UHS workarounds need, but even if so, it should at most apply to reads. I have observed many hangs when CMD25 response contained a CRC error. This patch fixes this without touching the actual UHS tuning workaround.

commit 43e5fee317f4b0a48992b8b07935b1a3ac20ce84 upstream. We found this issue on a 5G platform, during CMDQ error handling, if DMA status is active when it call msdc_reset_hw(), it means mmc host hw reset and DMA transfer will be parallel, mmc host may access sram region unexpectedly. According to the programming guide of mtk-sd host, it needs to wait for dma stop done after set dma stop. This change should be applied to all SoCs.

That lets program enter fail handling to cleanup_dev() in xillyusb_probe(). Check for 'xdev->msg_ep' is invalid in cleanup_dev() because 'xdev->msg_ep' did not set to NULL when was freed.

2021-11-18ce/gf100: fix incorrect CE0 address calculation on some GPUsBen Skeggs2-3/+2
commit 93f43ed81abec8c805e1b77eb1d20dbc51a24dc4 upstream. The code which constructs the modules for each engine present on the GPU passes -1 for 'instance' on non-instanced engines, which affects how the name for a sub-device is generated. This is then stored as 'instance 0' in nvkm_subdev.inst, so code can potentially be shared with earlier GPUs that only had a single instance of an engine. However, GF100's CE constructor uses this value to calculate the address of its falcon before it's translated, resulting in CE0 getting the wrong address. This slightly modifies the approach, always passing a valid instance for engines that *can* have multiple copies, and having the code for earlier GPUs explicitly ask for non-instanced name generation.
