2024-09-04bpf: add check for invalid name in btf_name_valid_section()Jeongjun Park
If the length of the name string is 1 and the value of name[0] is NULL byte, an OOB vulnerability occurs in btf_name_valid_section() and the return value is true, so the invalid name passes the check. To solve this, you need to check if the first position is NULL byte and if the first character is printable.

2024-09-04irqchip/apple-aic: Only access system registers on SoCs which provide themKonrad Dybcio
Starting from the A11 (T8015) SoC, Apple introuced system registers for fast IPI and UNCORE PMC control. These sysregs do not exist on earlier A7-A10 SoCs and trying to access them results in an instant crash.

2024-09-04irqchip/apple-aic: Add a new "Global fast IPIs only" feature levelNick Chan
Starting with the A11 (T8015) SoC, Apple began using arm64 sysregs for fast IPIs. However, on A11, there is no such things as "Local" fast IPIs, as the SYS_IMP_APL_IPI_RR_LOCAL_EL1 register does not seem to exist. Add a new feature level, used by the compatible "apple,t8015-aic", controlled by a static branch key named use_local_fast_ipi. When use_fast_ipi is true and use_local_fast_ipi is false, fast IPIs are used but all IPIs goes through the register SYS_IMP_APL_IPI_RR_GLOBAL_EL1, as "global" IPIs.

2024-09-04platform/x86: ideapad-laptop: Make the scope_guard() clear of its scopeAndy Shevchenko
First of all, it's a bit counterintuitive to have something like int err; ... scoped_guard(...) err = foo(...); if (err) return err; Second, with a particular kernel configuration and compiler version in one of such cases the objtool is not happy: ideapad-laptop.o: warning: objtool: .text.fan_mode_show: unexpected end of section I'm not an expert on all this, but the theory is that compiler and linker in this case can't understand that 'result' variable will be always initialized as long as no error has been returned. Assigning 'result' to a dummy value helps with this. Note, that fixing the scoped_guard() scope (as per above) does not make issue gone. That said, assign dummy value and make the scope_guard() clear of its scope. For the sake of consistency do it in the entire file.

The commit 'b1d90a86 ("drm/xe: Use the encoder suspend helper also used by the i915 driver")' didn't do anything wrong. It actually fixed a critical bug, because the encoder_suspend was never getting actually called because it was returning if (has_display(xe)) instead of if (!has_display(xe)).

Use of_property_present() to test for property presence rather than of_get_property(). This is part of a larger effort to remove callers of of_get_property() and similar functions. of_get_property() leaks the DT property data pointer which is a problem for dynamically allocated nodes which may be freed.

2024-09-04perf/aux: Fix AUX buffer serializationPeter Zijlstra
Ole reported that event->mmap_mutex is strictly insufficient to serialize the AUX buffer, add a per RB mutex to fully serialize it. Note that in the lock order comment the perf_event::mmap_mutex order was already wrong, that is, it nesting under mmap_lock is not new with this patch.

The ioremap() function doesn't return error pointers, it returns NULL on error so update the error handling. Also just return directly instead of calling iounmap() on the NULL pointer. Calling iounmap(NULL) doesn't cause a problem on ARM but on other architectures it can trigger a warning so it'a bad habbit.

The devm_clk_get_enabled() helpers: - call devm_clk_get() - call clk_prepare_enable() and register what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code and avoids the calls to clk_disable_unprepare(). While at it, use dev_err_probe consistently, and use its return value to return the error code.

2024-09-04arm64: trans_pgd: mark PTEs entries as valid to avoid dead kexec()Fares Mehanna
The reasons for PTEs in the kernel direct map to be marked invalid are not limited to kfence / debug pagealloc machinery. In particular, memfd_secret() also steals pages with set_direct_map_invalid_noflush(). When building the transitional page tables for kexec from the current kernel's page tables, those pages need to become regular writable pages, otherwise, if the relocation places kexec segments over such pages, a fault will occur during kexec, leading to host going dark during kexec. This patch addresses the kexec issue by marking any PTE as valid if it is not none. While this fixes the kexec crash, it does not address the security concern that if processes owning secret memory are not terminated before kexec, the secret content will be mapped in the new kernel without being scrubbed.
