2019-10-01f2fs: use generic EFSBADCRC/EFSCORRUPTEDChao Yu
[ Upstream commit 10f966bbf521bb9b2e497bbca496a5141f4071d0 ] f2fs uses EFAULT as error number to indicate filesystem is corrupted all the time, but generic filesystems use EUCLEAN for such condition, we need to change to follow others. This patch adds two new macros as below to wrap more generic error code macros, and spread them in code. EFSBADCRC EBADMSG /* Bad CRC detected */ EFSCORRUPTED EUCLEAN /* Filesystem is corrupted */ Reported-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Chao Yu <yuchao0@huawei.com> Acked-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
2019-10-01net/rds: Check laddr_check before calling itKa-Cheong Poon
[ Upstream commit 05733434ee9ae6548723a808647248583e347cca ] In rds_bind(), laddr_check is called without checking if it is NULL or not. And rs_transport should be reset if rds_add_bound() fails.

2019-10-01net/rds: An rds_sock is added too early to the hash tableKa-Cheong Poon
[ Upstream commit c5c1a030a7dbf8dd4e1fa4405ae9a89dc1d2a8db ] In rds_bind(), an rds_sock is added to the RDS bind hash table before rs_transport is set. This means that the socket can be found by the receive code path when rs_transport is NULL. And the receive code path de-references rs_transport for congestion update check. This can cause a panic. An rds_sock should not be added to the bind hash table before all the needed fields are set.

2019-10-01net_sched: check cops->tcf_block in tc_bind_tclass()Cong Wang
[ Upstream commit 8b142a00edcf8422ca48b8de88d286efb500cb53 ] At least sch_red and sch_tbf don't implement ->tcf_block() while still have a non-zero tc "class". Instead of adding nop implementations to each of such qdisc's, we can just relax the check of cops->tcf_block() in tc_bind_tclass(). They don't support TC filter anyway.

2019-10-01ACPI: video: Add new hw_changes_brightness quirk, set it on PB Easynote MZ35Hans de Goede
[ Upstream commit 4f7f96453b462b3de0fa18d18fe983960bb5ee7f ] Some machines change the brightness themselves when a brightness hotkey gets pressed, despite us telling them not to. This causes the brightness to go two steps up / down when the hotkey is pressed. This is esp. a problem on older machines with only a few brightness levels. This commit adds a new hw_changes_brightness quirk which makes acpi_video_device_notify() only call backlight_force_update(..., BACKLIGHT_UPDATE_HOTKEY) and not do anything else, notifying userspace that the brightness was changed and leaving it at that fixing the dual step problem.

2019-10-01Bluetooth: btrtl: HCI reset on close for Realtek BT chipJian-Hong Pan
[ Upstream commit 7af3f558aca74f2ee47b173f1c27f6bb9a5b5561 ] Realtek RTL8822BE BT chip on ASUS X420FA cannot be turned on correctly after on-off several times. Bluetooth daemon sets BT mode failed when this issue happens. Scanning must be active while turning off for this bug to be hit. bluetoothd[1576]: Failed to set mode: Failed (0x03) If BT is turned off, then turned on again, it works correctly again. According to the vendor driver, the HCI_QUIRK_RESET_ON_CLOSE flag is set during probing. So, this patch makes Realtek's BT reset on close to fix this issue.

2019-10-01Revert "f2fs: avoid out-of-range memory access"Chao Yu
[ Upstream commit a37d0862d17411edb67677a580a6f505ec2225f6 ] As Pavel Machek reported: "We normally use -EUCLEAN to signal filesystem corruption. Plus, it is good idea to report it to the syslog and mark filesystem as "needing fsck" if filesystem can do that." Still we need improve the original patch with: - use unlikely keyword - add message print - return EUCLEAN However, after rethink this patch, I don't think we should add such condition check here as below reasons: - We have already checked the field in f2fs_sanity_check_ckpt(), - If there is fs corrupt or security vulnerability, there is nothing to guarantee the field is integrated after the check, unless we do the check before each of its use, however no filesystem does that. - We only have similar check for bitmap, which was added due to there is bitmap corruption happened on f2fs' runtime in product. - There are so many key fields in SB/CP/NAT did have such check after f2fs_sanity_check_{sb,cp,..}. So I propose to revert this unneeded check. This reverts commit 56f3ce675103e3fb9e631cfb4131fc768bc23e9a.

In the non-existent case this causes a boot-time splat if CONFIG_DEBUG_VIRTUAL is enabled due to a call to virt_to_phys() with a NULL address. Instead we should check that the initrd actually exists and only attempt to free it if it does.

2019-10-01irqchip/gic-v3-its: Fix LPI release for Multi-MSI devicesMarc Zyngier
[ Upstream commit c9c96e30ecaa0aafa225aa1a5392cb7db17c7a82 ] When allocating a range of LPIs for a Multi-MSI capable device, this allocation extended to the closest power of 2. But on the release path, the interrupts are released one by one. This results in not releasing the "extra" range, leaking the its_device. Trying to reprobe the device will then fail. Fix it by releasing the LPIs the same way we allocate them.

commit 3a9236e97207f2469254b4098995159b80174d95 upstream. At higher sampling rate (e.g. 192.0 kHz), Alesis iO26 transfers 4 data channels per data block in CIP. Both iO14 and iO26 have the same contents in their configuration ROM. For this reason, ALSA Dice driver attempts to distinguish them according to the value of TX0_AUDIO register at probe callback. Although the way is valid at lower and middle sampling rate, it's lastly invalid at higher sampling rate because because the two models returns the same value for read transaction to the register. In the most cases, users just plug-in the device and ALSA dice driver detects it. In the case, the device runs at lower sampling rate and the driver detects expectedly. For this reason, this commit leaves the way to detect as is.

commit 4bcdec39c454c4e8f9512115bdcc3efec1ba5f55 upstream. Users have been seeing sound stability issues with max98090 codecs since: commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL") At first that commit broke sound for Chromebook Swanky and Clapper models, the problem was that the machine-driver has been controlling the wrong clock on those models since support for them was added. This was hidden by clk-pmc-atom.c keeping the actual clk on unconditionally. With the machine-driver controlling the proper clock, sound works again but we are seeing bug reports describing it as: low volume, "sounds like played at 10x speed" and instable. When these issues are hit the following message is seen in dmesg: "max98090 i2c-193C9890:00: PLL unlocked". Attempts have been made to fix this by inserting a delay between enabling the clk and enabling and checking the pll, but this has not helped. It seems that at least on boards which use pmc_plt_clk_0 as clock, if we ever disable the clk, the pll looses its lock and after that we get various issues. This commit fixes this by enabling the clock once at probe time on these boards. In essence this restores the old behavior of clk-pmc-atom.c always keeping the clk on on these boards.
