2024-11-22linux-user: Fix strace output for s390x mmap()Ilya Leoshkevich1-0/+7
print_mmap() assumes that mmap() receives arguments via memory if mmap2() is present. s390x (as opposed to s390) does not fit this pattern: it does not have mmap2(), but mmap() still receives arguments via memory. Fix by sharing the detection logic between syscall.c and strace.c.

2024-10-08linux-user: add strace support for openat2Michael Vogt1-0/+5
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 Vogt1-0/+13
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.

2021-05-18linux-user: Pass ka_restorer to do_sigactionRichard Henderson1-1/+1
The value of ka_restorer needs to be saved in sigact_table. At the moment, the attempt to save it in do_syscall is improperly clobbering user memory.

2021-05-18linux-user/alpha: Rename the sigaction restorer fieldRichard Henderson1-1/+1
Use ka_restorer, in line with TARGET_ARCH_HAS_KA_RESTORER vs TARGET_ARCH_HAS_SA_RESTORER, since Alpha passes this field as a syscall argument.

2021-03-09Remove deprecated target tilegxThomas Huth1-8/+2
TILE-Gx was only implemented in linux-user mode, but support for this CPU was removed from the upstream Linux kernel in 2018, and it has also been dropped from glibc, so there is no new Linux development taking place with this architecture. For running the old binaries, users can simply use older versions of QEMU.
