[PATCH 5.15] Revert "PCI: Use preserve_config in place of pci_flags"

by Terry Tritton

This reverts commit c1a1393f7844c645389e5f1a3f1f0350e0fb9316 which is commit 7246a4520b4bf1494d7d030166a11b5226f6d508 upstream. This patch causes a regression in cuttlefish/crossvm boot on arm64. The patch was part of a series that when applied will not cause a regression but this patch was backported to the 5.15 branch by itself. The other patches do not apply cleanly to the 5.15 branch.

[PATCH v6.1-v5.10] gpiolib: cdev: Fix use after free in lineinfo_changed_notify

by hsimeliere.opensource＠witekio.com

From: Zhongqiu Han <quic_zhonhan(a)quicinc.com> [ Upstream commit 02f6b0e1ec7e0e7d059dddc893645816552039da ] The use-after-free issue occurs as follows: when the GPIO chip device file is being closed by invoking gpio_chrdev_release(), watched_lines is freed by bitmap_free(), but the unregistration of lineinfo_changed_nb notifier chain failed due to waiting write rwsem. Additionally, one of the GPIO chip's lines is also in the release process and holds the notifier chain's read rwsem. Consequently, a race condition leads to the use-after-free of watched_lines. Here is the typical stack when issue happened: [free] gpio_chrdev_release() --> bitmap_free(cdev->watched_lines) <-- freed --> blocking_notifier_chain_unregister() --> down_write(&nh->rwsem) <-- waiting rwsem --> __down_write_common() --> rwsem_down_write_slowpath() --> schedule_preempt_disabled() --> schedule() [use] st54spi_gpio_dev_release() --> gpio_free() --> gpiod_free() --> gpiod_free_commit() --> gpiod_line_state_notify() --> blocking_notifier_call_chain() --> down_read(&nh->rwsem); <-- held rwsem --> notifier_call_chain() --> lineinfo_changed_notify() --> test_bit(xxxx, cdev->watched_lines) <-- use after free The side effect of the use-after-free issue is that a GPIO line event is being generated for userspace where it shouldn't. However, since the chrdev is being closed, userspace won't have the chance to read that event anyway. To fix the issue, call the bitmap_free() function after the unregistration of lineinfo_changed_nb notifier chain.

[PATCH v6.6-v6.1] block: fix uaf for flush rq while iterating tags

[PATCH] Revert v6.2-rc1 and later "ARM: dts: bcm2835-rpi: Use firmware clocks for display"

by H. Nikolaus Schaller

This reverts commit d02f02c28f5561cf5b2345f8b4c910bd98d18553. I tried to upgrade a RasPi 3B+ with Waveshare 7inch HDMI LCD from 6.1.y to 6.6.y but found that the display is broken with this log message: [ 17.776315] vc4-drm soc:gpu: bound 3f400000.hvs (ops vc4_drm_unregister [vc4]) [ 17.784034] platform 3f806000.vec: deferred probe pending Some tests revealed that while 6.1.y works, 6.2-rc1 is already broken but all newer kernels as well. And a bisect did lead me to this patch. I could repair several versions up to 6.13-rc7 by doing this revert. Newer kernels have just to take care of commit f702475b839c ("ARM: dts: bcm2835-rpi: Move duplicate firmware-clocks to bcm2835-rpi.dtsi") but that is straightforward.

[PATCH] irqchip/apple-aic: Only handle PMC interrupt as FIQ when configured to fire FIQ

by Nick Chan

The CPU PMU in Apple SoCs can be configured to fire its interrupt in one of several ways, and since Apple A11 one of the method is FIQ. Only handle the PMC interrupt as a FIQ when the CPU PMU has been configured to fire FIQs.

Frequent kernel messages related to IR keymap rc-cec with kernel 6.12.10 and HDMI monitor

by Farblos

This is on Debian testing with the following kernel, built from the tarball on kernel.org: Linux sappc1 6.12.10 #4 SMP PREEMPT_DYNAMIC Fri Jan 17 22:17:45 CET 2025 x86_64 GNU/Linux It is running on an 12th gen Intel Framework laptop, with monitor connected through Framework's USB-C-to-HDMI adapter (the 3rd gen one): https://knowledgebase.frame.work/hdmi-expansion-card-generations-Sk7AQKUv2 Since my kernel got upgraded to version 6.12.*, I get frequently journal messages like these: Jan 15 15:24:51 host01 kernel: Registered IR keymap rc-cec Jan 15 15:24:51 host01 kernel: rc rc0: DP-3 as /devices/pci0000:00/0000:00:02.0/rc/rc0 Jan 15 15:24:51 host01 kernel: input: DP-3 as /devices/pci0000:00/0000:00:02.0/rc/rc0/input146 Jan 15 15:24:51 host01 systemd-logind[1456]: Watching system buttons on /dev/input/event11 (DP-3) Jan 15 15:24:51 host01 Xorg[1663]: (II) config/udev: Adding input device DP-3 (/dev/input/event11) I tried to ignore these as long as they have been showing up during boot only or when screen resolution got changed using xrandr, but today I noticed that these repeat every 30 secs or so when my screen saver is active. Which then kind of floods the journal. With the previous 6.11.* kernel series I would see these messages only once, during startup. When using a DisplayPort adapter instead of the HDMI adapter, these messages do not show up either. I guess that it is not the CEC subsystem being responsible here, but rather some other component which triggers it more frequently than earlier. Any help on how to find more about this issue appreciated. Please CC me in replies. Thanks!
