[PATCH v4 1/2] driver core: Introduce device_{add,remove}_of_node()

by Herve Codina

An of_node can be set to a device using device_set_node(). This function cannot prevent any of_node and/or fwnode overwrites. When adding an of_node on an already present device, the following operations need to be done: - Attach the of_node if no of_node were already attached - Attach the of_node as a fwnode if no fwnode were already attached This is the purpose of device_add_of_node(). device_remove_of_node() reverts the operations done by device_add_of_node().

[PATCH] arch/Kconfig: Move SPECULATION_MITIGATIONS to arch/Kconfig

by Song Liu

SPECULATION_MITIGATIONS is currently defined only for x86. As a result, IS_ENABLED(CONFIG_SPECULATION_MITIGATIONS) is always false for other archs. f337a6a21e2f effectively set "mitigations=off" by default on non-x86 archs, which is not desired behavior. Jakub observed this change when running bpf selftests on s390 and arm64. Fix this by moving SPECULATION_MITIGATIONS to arch/Kconfig so that it is available in all archs and thus can be used safely in kernel/cpu.c Fixes: f337a6a21e2f ("x86/cpu: Actually turn off mitigations by default for SPECULATION_MITIGATIONS=n") Cc: stable(a)vger.kernel.org Cc: Sean Christopherson <seanjc(a)google.com> Cc: Ingo Molnar <mingo(a)kernel.org> Cc: Daniel Sneddon <daniel.sneddon(a)linux.intel.com> Cc: Jakub Kicinski <kuba(a)kernel.org> Signed-off-by: Song Liu <song(a)kernel.org> --- arch/Kconfig | 10 ++++++++++ arch/x86/Kconfig | 10 ---------- 2 files changed, 10 insertions(+), 10 deletions(-) diff --git a/arch/Kconfig b/arch/Kconfig index 9f066785bb71..8f4af75005f8 100644 --- a/arch/Kconfig +++ b/arch/Kconfig @@ -1609,4 +1609,14 @@ config CC_HAS_SANE_FUNCTION_ALIGNMENT # strict alignment always, even with -falign-functions. def_bool CC_HAS_MIN_FUNCTION_ALIGNMENT || CC_IS_CLANG +menuconfig SPECULATION_MITIGATIONS + bool "Mitigations for speculative execution vulnerabilities" + default y + help + Say Y here to enable options which enable mitigations for + speculative execution hardware vulnerabilities. + + If you say N, all mitigations will be disabled.

[PATCH v2] fbdev: fix incorrect address computation in deferred IO

by Nam Cao

With deferred IO enabled, a page fault happens when data is written to the framebuffer device. Then driver determines which page is being updated by calculating the offset of the written virtual address within the virtual memory area, and uses this offset to get the updated page within the internal buffer. This page is later copied to hardware (thus the name "deferred IO"). This offset calculation is only correct if the virtual memory area is mapped to the beginning of the internal buffer. Otherwise this is wrong. For example, if users do: mmap(ptr, 4096, PROT_WRITE, MAP_FIXED | MAP_SHARED, fd, 0xff000); Then the virtual memory area will mapped at offset 0xff000 within the internal buffer. This offset 0xff000 is not accounted for, and wrong page is updated. Correct the calculation by using vmf->pgoff instead. With this change, the variable "offset" will no longer hold the exact offset value, but it is rounded down to multiples of PAGE_SIZE. But this is still correct, because this variable is only used to calculate the page offset.

[PATCH 5/6] arm64: dts: qcom: sc8280xp-x13s: fix touchscreen power on

by Johan Hovold

The Elan eKTH5015M touch controller on the X13s requires a 300 ms delay before sending commands after having deasserted reset during power on. Switch to the Elan specific binding so that the OS can determine the required power-on sequence and make sure that the controller is always detected during boot. Note that the always-on 1.8 V supply (s10b) is not used by the controller directly and should not be described.

[PATCH] efi: libstub: only free priv.runtime_map when allocated

by Hagar Hemdan

priv.runtime_map is only allocated when efi_novamap is not set. Otherwise, it is an uninitialized value. In the error path, it is freed unconditionally. Avoid passing an uninitialized value to free_pool. Free priv.runtime_map only when it was allocated.

That out of bounds access is ultimately caused because the inode has an inode number with the invalid value of zero, which was not checked. The reason this causes the out of bounds access is due to following sequence of events: 1. Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number). 2. When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed. This patch adds a sanity check which checks that the inode number is not zero when the inode is created and returns -EINVAL if it is.
