The user is reporting an issue with qemu-aarch64 where certain tests fail due to a segmentation fault or infinite loops. The problem is traced back to an ABI incompatibility between the Linux Kernel and QEMU, specifically the size discrepancy of the siginfo structure. + +Looking into the details, the user points out that the TARGET_SI_PAD_SIZE in QEMU's syscall_defs.h is calculated differently than the Linux Kernel's SI_PAD_SIZE. The QEMU definition uses TARGET_SI_MAX_SIZE divided by the size of int minus 3, while the kernel's version subtracts the __ARCH_SI_PREAMBLE_SIZE (which is 4 * sizeof(int) for AArch64) from SI_MAX_SIZE and then divides by the size of int. + +This suggests that the issue is related to how QEMU is handling the signal information structure, which is part of the system call interface between the user space and the kernel. Since the structure size is different, when a signal is delivered, QEMU might be reading or writing the siginfo structure incorrectly, leading to crashes or infinite loops during stack unwinding, especially when exceptions are involved. + +The problem is not with a specific syscall but rather with the structure that's used during syscall handling for signals. However, since the issue stems from the definition of a structure that's part of the system call's data structures, this would fall under syscall handling. The incorrect padding size affects how QEMU interprets the signal information passed during syscalls, leading to the observed runtime errors. So the category here is syscall. +</think> + +syscall \ No newline at end of file |
