CVS commit: src/sys/arch
Module Name:src Committed By: maxv Date: Mon Apr 13 05:40:26 UTC 2020 Modified Files: src/sys/arch/aarch64/aarch64: aarch64_machdep.c cpuswitch.S pmap.c pmapboot.c trap.c vectors.S src/sys/arch/aarch64/conf: Makefile.aarch64 src/sys/arch/arm/conf: files.arm src/sys/arch/arm/include: asm.h src/sys/arch/evbarm/conf: GENERIC64 Log Message: Add support for Branch Target Identification (BTI). On the executable pages that have the GP (Guarded Page) bit, the semantic of the "br" and "blr" instructions is changed: the CPU expects the first instruction of the jump/call target to be "bti", and faults if it isn't. We add the GP bit on the kernel .text pages (and incidentally the .rodata pages, but we don't care). The compiler adds a "bti c" instruction at the beginning of each C function. We modify the ENTRY() macros to manually add "bti c" in the asm functions. cpuswitch.S needs a specific change: with "br x27" the CPU expects "bti j", which is bad because the functions begin with "bti c"; switch to "br x16", for the CPU to accept "bti c". BTI helps defend against JOP/COP. Tested on Qemu.

We will do this another way, and separate KNF fixes from the critical functional change. ok msaitoh KNF Reject overly large widths, from mlelstv. We are returning an ACPI_INTEGER (= uint64_t), so it doesn't make sense to handle more than 64 bits. Apparently there are some ACPIs out there that ask for unreasonably large widths here. Just reject those requests, rather than writing past the caller's stack buffer. Previously we attempted to fix this by copying byte by byte as large as the caller asked, in order to avoid the undefined behaviour of shifting past the size of ACPI_INTEGER, but that just turned a shift (which might have been harmless on real machines) into a stack buffer overflow (!). ok msaitoh To generate a diff of this commit: cvs rdiff -u -r1.75.20.1 -r1.75.20.2 src/sys/dev/acpi/acpi_ec.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.

CVS commit: src/sys/arch
Module Name:src Committed By: maxv Date: Sun Apr 12 07:49:58 UTC 2020 Modified Files: src/sys/arch/aarch64/aarch64: aarch64_machdep.c cpufunc.c cpuswitch.S db_trace.c genassym.cf locore.S vectors.S vm_machdep.c src/sys/arch/aarch64/conf: Makefile.aarch64 src/sys/arch/aarch64/include: armreg.h asm.h cpufunc.h proc.h src/sys/arch/arm/conf: files.arm src/sys/arch/evbarm/conf: GENERIC64 Log Message: Add support for Pointer Authentication (PAC). We use the "pac-ret" option, to sign the return instruction pointer on function entry, and authenticate it on function exit. This acts as a mitigation against ROP. The authentication uses a per-lwp (secret) I-A key stored in the 128bit APIAKey register and part of the lwp context. During lwp creation, the kernel generates a random key, and during context switches, it installs the key of the target lwp on the CPU. Userland cannot read the APIAKey register directly. However, it can sign its pointers with it, because the register is architecturally shared between userland and the kernel. Although part of the CPU design, it is a bit of an undesired behavior, because it allows to forge valid kernel pointers from userland. To avoid that, we don't share the key with userland, and rather switch it in EL0<->EL1 transitions. This means that when userland executes, a different key is loaded in APIAKey than the one the kernel uses. For now the userland key is a fixed 128bit zero value. The DDB stack unwinder is changed to strip the authentication code from the pointers in lr. Two problems are known: * Currently the idlelwps' keys are not really secret. This is because the RNG is not yet available when we spawn these lwps. Not overly important, but would be nice to fix with UEFI RNG. * The key switching in EL0<->EL1 transitions is not the most optimized code on the planet. Instead of checking aarch64_pac_enabled, it would be better to hot-patch the code at boot time, but there currently is no hot-patch support on aarch64. Tested on Qemu.
