s->dict.allocated was initialized to 0 but never set after a successful allocation, thus the code always thought that the dictionary buffer has to be reallocated.

2019-11-15mm: mempolicy: fix the wrong return value and potential pages leak of mbindYang Shi1-5/+9
Commit d883544515aa ("mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified") fixed the return value of mbind() for a couple of corner cases. But, it altered the errno for some other cases, for example, mbind() should return -EFAULT when part or all of the memory range specified by nodemask and maxnode points outside your accessible address space, or there was an unmapped hole in the specified memory range specified by addr and len. Fix this by preserving the errno returned by queue_pages_range(). And, the pagelist may be not empty even though queue_pages_range() returns error, put the pages back to LRU since mbind_range() is not called to really apply the policy so those pages should not be migrated, this is also the old behavior before the problematic commit.

2019-11-15i2c: acpi: Force bus speed to 400KHz if a Silead touchscreen is presentHans de Goede1-1/+27
Many cheap devices use Silead touchscreen controllers. Testing has shown repeatedly that these touchscreen controllers work fine at 400KHz, but for unknown reasons do not work properly at 100KHz. This has been seen on both ARM and x86 devices using totally different i2c controllers. On some devices the ACPI tables list another device at the same I2C-bus as only being capable of 100KHz, testing has shown that these other devices work fine at 400KHz (as can be expected of any recent I2C hw). This commit makes i2c_acpi_find_bus_speed() always return 400KHz if a Silead touchscreen controller is present, fixing the touchscreen not working on devices which ACPI tables' wrongly list another device on the same bus as only being capable of 100KHz. Specifically this fixes the touchscreen on the Jumper EZpad 6 m4 not working.

2019-11-15Merge branch 'ptp-Validate-the-ancillary-ioctl-flags-more-carefully'David S. Miller11-8/+156
Richard Cochran says: ==================== ptp: Validate the ancillary ioctl flags more carefully. The flags passed to the ioctls for periodic output signals and time stamping of external signals were never checked, and thus formed a useless ABI inadvertently. More recently, a version 2 of the ioctls was introduced in order make the flags meaningful. This series tightens up the checks on the new ioctl flags. - Patch 1 ensures at least one edge flag is set for the new ioctl. - Patches 2-7 are Jacob's recent checks, picking up the tags. - Patch 8 introduces a "strict" flag for passing to the drivers when the new ioctl is used. - Patches 9-12 implement the "strict" checking in the drivers. - Patch 13 extends the test program to exercise combinations of flags. ==================== Signed-off-by: David S.

2019-11-15net: reject PTP periodic output requests with unsupported flagsJacob Keller7-0/+27
Commit 823eb2a3c4c7 ("PTP: add support for one-shot output") introduced a new flag for the PTP periodic output request ioctl. This flag is not currently supported by any driver. Fix all drivers which implement the periodic output request ioctl to explicitly reject any request with flags they do not understand. This ensures that the driver does not accidentally misinterpret the PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future. This is important for forward compatibility: if a new flag is introduced, the driver should reject requests to enable the flag until the driver has actually been modified to support the flag in question.

Commit 0ce1822c2a08 ("vxlan: add adjacent link to limit depth level") changed the VXLAN device to be an upper of the physical device which causes mlxsw to veto the creation of the VXLAN device with "Unknown upper device type". This is OK as this configuration is not supported, but it prevents us from testing bad flows involving the enslavement of VXLAN devices with a physical device to a bridge, regardless if the physical device is an mlxsw netdev or not.

2019-11-15afs: Fix race in commit bulk status fetchDavid Howells1-1/+6
When a lookup is done, the afs filesystem will perform a bulk status-fetch operation on the requested vnode (file) plus the next 49 other vnodes from the directory list (in AFS, directory contents are downloaded as blobs and parsed locally). When the results are received, it will speculatively populate the inode cache from the extra data. However, if the lookup races with another lookup on the same directory, but for a different file - one that's in the 49 extra fetches, then if the bulk status-fetch operation finishes first, it will try and update the inode from the other lookup. If this other inode is still in the throes of being created, however, this will cause an assertion failure in afs_apply_status(): BUG_ON(test_bit(AFS_VNODE_UNSET, &vnode->flags)); on or about fs/afs/inode.c:175 because it expects data to be there already that it can compare to. Fix this by skipping the update if the inode is being created as the creator will presumably set up the inode with the same information.

2019-11-15ALSA: hda: hdmi - fix port numbering for ICL and TGL platformsKai Vehmanen1-6/+6
Semantics of port#0 differ between ICL and TGL: ICL port#0 -> never used for HDAudio ICL port#1 -> should be mapped to first pin (0x04) TGL port#0 -> typically not used, but HW has the support, so should be mapped to first pin (0x04) TGL port#1 -> should be mapped to 2nd pin (0x06) Refactor the port mapping logic to allow to take the above differences into account. Fixes issues with HDAudio on some TGL platforms.

2019-11-15ASoC: soc-core: care card_probed at soc_cleanup_card_resources()Kuninori Morimoto1-5/+10
soc_cleanup_card_resources() will call card->remove(), but it should be called if card->probe() or card->late_probe() are called. snd_soc_bind_card() might be error before calling card->probe() / card->late_probe(). In that time, card->remove() will be called. This patch adds card_probed parameter to judge it.

2019-11-15ASoC: soc-core: call snd_soc_dapm_shutdown() at soc_cleanup_card_resources()Kuninori Morimoto1-1/+2
It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc. It is easy to create bug at the such code, and it will be difficult to debug. snd_soc_bind_card() is calling snd_soc_dapm_init() for both card and component. Let's call paired snd_soc_dapm_shutdown() at paired soc_cleanup_card_resources().

2019-11-15ASoC: wm8904: fix regcache handlingMichael Walle1-0/+1
The current code assumes that the power is turned off in SND_SOC_BIAS_OFF. If there are no actual regulator the codec isn't turned off and the registers are not reset to their default values but the regcache is still marked as dirty. Thus a value might not be written to the hardware if it is set to the default value. Do a software reset before turning off the power to make sure the registers are always reset to their default states.
