* linux-user: use 'max' instead of 'qemu32' / 'qemu64' by defaultDaniel P. Berrangé2022-09-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'qemu64' CPU model implements the least featureful x86_64 CPU that's possible. Historically this hasn't been an issue since it was rare for OS distros to build with a higher mandatory CPU baseline. With RHEL-9, however, the entire distro is built for the x86_64-v2 ABI baseline: https://developers.redhat.com/blog/2021/01/05/building-red-hat-enterprise-linux-9-for-the-x86-64-v2-microarchitecture-level It is likely that other distros may take similar steps in the not too distant future. For example, it has been suggested for Fedora on a number of occasions. This new baseline is not compatible with the qemu64 CPU model though. While it is possible to pass a '-cpu xxx' flag to qemu-x86_64, the usage of QEMU doesn't always allow for this. For example, the args are typically controlled via binfmt rules that the user has no ability to change. This impacts users who are trying to use podman on aarch64 platforms, to run containers with x86_64 content. There's no arg to podman that can be used to change the qemu-x86_64 args, and a non-root user of podman can not change binfmt rules without elevating privileges: https://github.com/containers/podman/issues/15456#issuecomment-1228210973 Changing to the 'max' CPU model gives 'qemu-x86_64' maximum compatibility with binaries it is likely to encounter in the wild, and not likely to have a significant downside for existing usage. Most other architectures already use an 'any' CPU model, which is often mapped to 'max' (or similar) already, rather than the oldest possible CPU model. For the sake of consistency the 'i386' architecture is also changed from using 'qemu32' to 'max'.

* linux-user: Correct definition of stack_tLemonBoy2020-11-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Some platforms used the wrong definition of stack_t where the flags and size fields were swapped or where the flags field had type ulong instead of int. Due to the presence of padding space in the structure and the prevalence of little-endian machines this problem went unnoticed for a long time. The type definitions have been cross-checked with the ones defined in the Linux kernel v5.9, plus some older versions for a few architecture that have been removed and Xilinx's kernel fork for NiosII [1]. The bsd-user headers remain unchanged as I don't know if they are wrong or not.

* linux-user: Add generic 'termbits.h' for some archsFilip Bozuta2020-08-271-253/+1Star
| | | | | | | | | | | | | | | | | | | | | This patch introduces a generic 'termbits.h' file for following archs: 'aarch64', 'arm', 'i386, 'm68k', 'microblaze', 'nios2', 'openrisc', 'riscv', 's390x', 'x86_64'. Since all of these archs have the same termios flag values and same ioctl_tty numbers, there is no need for a separate 'termbits.h' file for each one of them. For that reason one generic 'termbits.h' file was added for all of them and an '#include' directive was added for this generic file in every arch 'termbits.h' file. Also, some of the flag values that were missing were added in this generic file so that it matches the generic 'termibts.h' and 'ioctls.h' files from the kernel: 'asm-generic/termbits.h' and 'asm-generic/ioctls.h'.

* linux-user: Add strace support for printing arguments of syscalls used to ↵Filip Bozuta2020-08-271-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lock and unlock memory This patch implements strace argument printing functionality for following syscalls: * mlock, munlock, mlockall, munlockall - lock and unlock memory int mlock(const void *addr, size_t len) int munlock(const void *addr, size_t len) int mlockall(int flags) int munlockall(void) man page: https://man7.org/linux/man-pages/man2/mlock.2.html Implementation notes: Syscall mlockall() takes an argument that is composed of predefined values which represent flags that determine the type of locking operation that is to be performed. For that reason, a printing function "print_mlockall" was stated in file "strace.list". This printing function uses an already existing function "print_flags()" to print the "flags" argument. These flags are stated inside an array "mlockall_flags" that contains values of type "struct flags". These values are instantiated using an existing macro "FLAG_TARGET()" that crates aproppriate target flag values based on those defined in files '/target_syscall.h'. These target flag values were changed from "TARGET_MLOCKALL_MCL*" to "TARGET_MCL_*" so that they can be aproppriately set and recognised in "strace.c" with "FLAG_TARGET()". Value for "MCL_ONFAULT" was added in this patch. This value was also added in "syscall.c" in function "target_to_host_mlockall_arg()". Because this flag value was added in kernel version 4.4, it is enwrapped in an #ifdef directive (both in "syscall.c" and in "strace.c") as to support older kernel versions. The other syscalls have only primitive argument types, so the rest of the implementation was handled by stating an appropriate printing format in file "strace.list". Syscall mlock2() is not implemented in "syscall.c" and thus it's argument printing is not implemented in this patch.

| | | | | | | | | | | | | | The most interesting or most complicated part here is the syscall_nr.h generators. In order to keep the generation logic all in meson.build, I am adding to config_target the name of the .tbl file, and making the generated file syscall<SUFFIX>_nr.h for input file syscall<SUFFIX>.tbl. For architectures where the input file is not named syscall_nr.tbl, syscall_nr.h has to be a source file; it's just a forwarder for x86 (i386/x86_64), while for MIPS64 it chooses between N32 and N64 ABIs.

| | | | | | | | | | | | | The argument to the mlockall system call is not necessarily the same on all platforms and thus may require translation prior to passing to the host. For example, PowerPC 64 bit platforms define values for MCL_CURRENT (0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms (0x1 and 0x2, respectively) Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

* linux-user: set minimum kernel version to 2.6.32Riku Voipio2014-03-101-0/+1
| | | | | | | | | | | | | | | Popular glibc based distributions[1] require minimum 2.6.32 as kernel version. For some targets 2.6.18 would be enough, but dropping so low would mean some suboptimal system calls could get used. Set the minimum kernel advertized to 2.6.32 for all architectures but aarch64 to ensure working qemu linux-user in case host kernel is older.
