2024-10-22linux-user: Fix build failure caused by missing __u64 on muslYao Zi
Commit 9651cead2f ("linux-user: add openat2 support in linux-user") ships a definition of struct open_how_ver0 while assuming type __u64 is available in code, which is not the case when building QEMU on musl. Let's replaces __u64 with uint64_t.

2024-10-08linux-user: add strace support for openat2Michael Vogt
This commit adds support for the `openat2()` to `QEMU_STRACE`. It will use the `openat2.h` header if available to create user readable flags for the `resolve` argument but does not require the header otherwise. It also makes `copy_struct_from_user()` available via `qemu.h` and `open_how_ver0` via `syscall_defs.h` so that strace.c can use them.

2024-10-08linux-user: add openat2 support in linux-userMichael Vogt
This commit adds support for the `openat2()` syscall in the `linux-user` userspace emulator. It is implemented by extracting a new helper `maybe_do_fake_open()` out of the exiting `do_guest_openat()` and share that with the new `do_guest_openat2()`. Unfortunately we cannot just make do_guest_openat2() a superset of do_guest_openat() because the openat2() syscall is stricter with the argument checking and will return an error for invalid flags or mode combinations (which open()/openat() will ignore). The implementation is similar to SYSCALL_DEFINE(openat2), i.e. a new `copy_struct_from_user()` is used that works the same as the kernels version to support backwards-compatibility for struct syscall argument. Instead of including openat2.h we create a copy of `open_how` as `open_how_ver0` to ensure that if the structure grows we can log a LOG_UNIMP warning. Note that in this commit using openat2() for a "faked" file in /proc will honor the "resolve" flags for RESOLVE_NO_{MAGIC,SYM}LINKS for path based access to /proc/self/exe (which is the only magic link we support for faked files). Note it will not catch special access via e.g. dirfd. This is not great but it seems similar to the exiting behavior when openat() is called with a dirfd to "/proc". Here too the fake file lookup may not catch the special file because no dirfd is used to determine if the path is in /proc.
