[PATCH] ovl: properly handle large files in ovl_security_fileattr

by Oleksandr Tymoshenko

dentry_open in ovl_security_fileattr fails for any file larger than 2GB if open method of the underlying filesystem calls generic_file_open (e.g. fusefs). The issue can be reproduce using the following script: (passthrough_ll is an example app from libfuse). $ D=/opt/test/mnt $ mkdir -p ${D}/{source,base,top/uppr,top/work,ovlfs} $ dd if=/dev/zero of=${D}/source/zero.bin bs=1G count=2 $ passthrough_ll -o source=${D}/source ${D}/base $ mount -t overlay overlay \ -olowerdir=${D}/base,upperdir=${D}/top/uppr,workdir=${D}/top/work \ ${D}/ovlfs $ chmod 0777 ${D}/mnt/ovlfs/zero.bin Running this script results in "Value too large for defined data type" error message from chmod.

[PATCH] signal: restore the override_rlimit logic

by Roman Gushchin

Prior to commit d64696905554 ("Reimplement RLIMIT_SIGPENDING on top of ucounts") UCOUNT_RLIMIT_SIGPENDING rlimit was not enforced for a class of signals. However now it's enforced unconditionally, even if override_rlimit is set. This behavior change caused production issues. For example, if the limit is reached and a process receives a SIGSEGV signal, sigqueue_alloc fails to allocate the necessary resources for the signal delivery, preventing the signal from being delivered with siginfo. This prevents the process from correctly identifying the fault address and handling the error. From the user-space perspective, applications are unaware that the limit has been reached and that the siginfo is effectively 'corrupted'. This can lead to unpredictable behavior and crashes, as we observed with java applications. Fix this by passing override_rlimit into inc_rlimit_get_ucounts() and skip the comparison to max there if override_rlimit is set. This effectively restores the old behavior.

[PATCH v3] usb: dwc3: core: Fix system suspend on TI AM62 platforms

by Roger Quadros

Since commit 6d735722063a ("usb: dwc3: core: Prevent phy suspend during init"), system suspend is broken on AM62 TI platforms. Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY bits (hence forth called 2 SUSPHY bits) were being set during core initialization and even during core re-initialization after a system suspend/resume. These bits are required to be set for system suspend/resume to work correctly on AM62 platforms. Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget driver is not loaded and started. For Host mode, the 2 SUSPHY bits are set before the first system suspend but get cleared at system resume during core re-init and are never set again. This patch resovles these two issues by ensuring the 2 SUSPHY bits are set before system suspend and restored to the original state during system resume.

[PATCH] drm/bridge: it6505: Fix inverted reset polarity

by Chen-Yu Tsai

The IT6505 bridge chip has a active low reset line. Since it is a "reset" and not an "enable" line, the GPIO should be asserted to put it in reset and deasserted to bring it out of reset during the power on sequence. The polarity was inverted when the driver was first introduced, likely because the device family that was targeted had an inverting level shifter on the reset line. The MT8186 Corsola devices already have the IT6505 in their device tree, but the whole display pipeline is actually disabled and won't be enabled until some remaining issues are sorted out. The other known user is the MT8183 Kukui / Jacuzzi family; their device trees currently do not have the IT6505 included. Fix the polarity in the driver while there are no actual users.

[PATCH] arm64: dts: mediatek: mt8186-corsola: Fix IT6505 reset line polarity

by Chen-Yu Tsai

The reset line of the IT6505 bridge chip is active low, not active high. It was incorrectly inverted in the device tree as the implementation at the time incorrectly inverted the polarity in its driver, due to a prior device having an inline inverting level shifter. Fix the polarity now while the external display pipeline is incomplete, thereby avoiding any impact to running systems. A matching fix for the driver should be included if this change is backported.

Backport smb client char/block fixes

by Pali Rohár

Hello, I would like to propose backporting these two commits into stable: * 663f295e3559 ("smb: client: fix parsing of device numbers") * a9de67336a4a ("smb: client: set correct device number on nfs reparse points") Linux SMB client without these two recent fixes swaps device major and minor numbers, which makes basically char/block device nodes unusable. Commit 663f295e3559 ("smb: client: fix parsing of device numbers") should have had following Fixes line: Fixes: 45e724022e27 ("smb: client: set correct file type from NFS reparse points") And commit a9de67336a4a ("smb: client: set correct device number on nfs reparse points") should have contained line: Fixes: 102466f303ff ("smb: client: allow creating special files via reparse points") Pali

[PATCH v4] usb: typec: qcom-pmic: init value of hdr_len/txbuf_len earlier
