Sadly that has not yet fully concluded by now, patches got sent in https://mail.gnu.org/archive/html/qemu-devel/2026-01/msg00129.html but not yet fully merged. We need to re-check what we could merge along 10.2 in the next few days.
Or we merge 10.2 but add this as a test fix later but before 26.04 comes out. That is ok for 26.04, but further delays the SRU of the same to older releases which can affect running the new release there :-/ -- 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: Won't Fix 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
