The user provided some details about an issue with ARM v8.3a pauth instructions not working as expected. Let's break down what they've said. + +The host is Ubuntu 19.10 on an x86_64 machine, and the QEMU version is a specific commit from master. They're testing with two pauth instructions: paciasp and autiasp. The test involves corrupting the LR (link register) just before the autiasp instruction. + +The expected behavior is that when the pointer in LR is corrupted, the autiasp should fail to authenticate it and place an invalid pointer. However, what's happening instead is that autiasp successfully authenticates the corrupted pointer, which shouldn't be possible. + +The user also mentioned adding traces in QEMU code and found that "pauth_computepac" isn't handling truncation properly. They provided examples where even with different inputs (like 0x31000000400664 vs. 0x310040008743ec), the top_bit and bot_bit remain the same, which is incorrect because they should vary based on the input. + +So, looking at the possible categories: instruction, syscall, runtime. + +The issue seems to be related to how QEMU handles specific ARM instructions (pauth in this case). The problem arises during the execution of these instructions, leading to incorrect behavior. It's not a syscall error or something that happens at runtime unrelated to instruction processing. + +Therefore, it should fall under the "instruction" category because the bug is about the faulty handling of certain instructions by QEMU. +</think> + +instruction \ No newline at end of file |
