[ Upstream commit ee684de ] As shown in [1], it is possible to corrupt a BPF ELF file such that arbitrary BPF instructions are loaded by libbpf. This can be done by setting a symbol (BPF program) section offset to a large (unsigned) number such that <section start + symbol offset> overflows and points before the section data in the memory. Consider the situation below where: - prog_start = sec_start + symbol_offset <-- size_t overflow here - prog_end = prog_start + prog_size prog_start sec_start prog_end sec_end | | | | v v v v .....................|################################|............ The report in [1] also provides a corrupted BPF ELF which can be used as a reproducer: $ readelf -S crash Section Headers: [Nr] Name Type Address Offset Size EntSize Flags Link Info Align ...

[ Upstream commit dd13316 ] The platform profile driver is loaded even on platforms that do not have ACPI enabled. The initialization of the sysfs entries was recently moved from platform_profile_register() to the module init call, and those entries need acpi_kobj to be initialized which is not the case when ACPI is disabled. This results in the following warning: WARNING: CPU: 5 PID: 1 at fs/sysfs/group.c:131 internal_create_group+0xa22/0xdd8 Modules linked in: CPU: 5 UID: 0 PID: 1 Comm: swapper/0 Tainted: G W 6.15.0-rc7-dirty #6 PREEMPT Tainted: [W]=WARN Hardware name: riscv-virtio,qemu (DT) epc : internal_create_group+0xa22/0xdd8 ra : internal_create_group+0xa22/0xdd8 Call Trace: internal_create_group+0xa22/0xdd8 sysfs_create_group+0x22/0x2e platform_profile_init+0x74/0xb2 do_one_initcall+0x198/0xa9e kernel_init_freeable+0x6d8/0x780 kernel_init+0x28/0x24c ret_from_fork+0xe/0x18 Fix this by checking if ACPI is enabled before trying to create sysfs entries.

[ Upstream commit eedf3e3 ] ACPICA commit 1c28da2242783579d59767617121035dafba18c3 This was originally done in NetBSD: https://github.com/NetBSD/src/commit/b69d1ac3f7702f67edfe412e4392f77d09804910 and is the correct alternative to the smattering of `memcpy`s I previously contributed to this repository. This also sidesteps the newly strict checks added in UBSAN: https://github.com/llvm/llvm-project/commit/792674400f6f04a074a3827349ed0e2ac10067f6 Before this change we see the following UBSAN stack

A lot of Dell devices default to “RAID” over AHCI for the storage configuration in the system firmware. In this case, the device is not detected. A driver is needed for that added in commit 34a956d (Add support driver for Intel Rapid Start Technology) in 2013.
PS: It might make sense to switch to AHCI nevertheless due to faster performance. But the Internet says to test yourself.
