https://lore.kernel.org/qemu- devel/?q=Luca+Bonissi+%3Cqemu%40bonslack.org%3E These extra patches seem to be needed for target architectures like PPC and MIPS that don't use generic/termbits.h. S390X should be good as it uses generic/termbits.h. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/2133804 Title: QEMU does not emulate IOCTL TCGETS2 Status in QEMU: New Status in qemu package in Ubuntu: Confirmed Status in qemu source package in Jammy: Confirmed Status in qemu source package in Noble: Confirmed Status in qemu source package in Plucky: Confirmed Status in qemu source package in Questing: Confirmed Status in qemu source package in Resolute: Confirmed Bug description: In Ubuntu 25.10 we moved to glibc 2.42. Here glibc has changed the implementation of isatty(). It now uses IOCTL TCGETS2 instead of TCGETS. TCGETS2 is not emulated by static QEMU (qemu-riscv64, qemu- arm64, ...). This leads to failures in containers for foreign architectures. E.g. no console prompt is displayed. A detailed analysis is contained in LP #2133188. A proper implementation of the missing IOCTLs will include: Functions: in linux-user/syscall.c: host_to_target_termios2() target_to_host_termios2() print_termios2() Definitions: in linux-user/syscall.c #define termios2 host_termios2 in linux-user/syscall_types.h STRUCT_SPECIAL(termios2) in linux-user/ioctls.h: IOCTL(TCGETS2, IOC_R, MK_PTR(MK_STRUCT(STRUCT_termios2))) IOCTL(TCSETS2, IOC_W, MK_PTR(MK_STRUCT(STRUCT_termios2))) IOCTL(TCSETSF2, IOC_W, MK_PTR(MK_STRUCT(STRUCT_termios2))) IOCTL(TCSETSW2, IOC_W, MK_PTR(MK_STRUCT(STRUCT_termios2))) in linux-user/user-internals.h: void print_termios2(void *arg); To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/2133804/+subscriptions
