The issue occurs when using Go on an s390x guest under Debian x64 host. The error message points to a TLS problem: "tls: bad record MAC." + +From the commit mentioned (08ef92d556c5), something changed that affects hashing. The user suspects it's related to z/Arch vector facilities, which are hardware features used for acceleration. + +In QEMU, s390x uses TCG for emulation when KVM isn't available or enabled. If there's a bug in the TCG code handling vector instructions, it might cause incorrect calculations, including hashes. Since Go relies on cryptographic operations (like TLS), any hash error could lead to issues like this. + +TLS errors can result from incorrect encryption, which ties back to how hashes are computed. If the hash calculation is wrong due to a bug in QEMU's TCG implementation for s390x, it would affect user-level processes running Go code that uses these operations. + +So, since the issue arises in the guest's user space application (Go build process), but the root cause seems to be in how QEMU emulates certain instructions, this is a system-mode issue because it involves lower-level emulation and possibly device or instruction handling. +</think> + +system \ No newline at end of file |
