qemu (1:10.1.2+ds-3) unstable; urgency=medium
* d/control: qemu-system-xen: add the forgotten ipxe-qemu dependency
qemu-system binaries require pxe boot roms for the network adaptors.
When splitting qemu-system-xen into its own package, this dependency
has been forgotten initally, but has been enabled for bookworm (#1035676).
However, this change were lost when uploading the next version of qemu
aimed for trixie. So trixie has this issue too, despite it's been fixed
in bookworm already. (Closes: #1035676, #1120146)

QEMU does not emulate IOCTL TCGETS2

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);
