2020-11-11linux-user: Correct definition of stack_tLemonBoy1-3/+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.

2020-11-10linux-user/sparc: Don't zero high half of PC, NPC, PSR in sigreturnPeter Maydell1-1/+1
The function do_sigreturn() tries to store the PC, NPC and PSR in uint32_t local variables, which implicitly drops the high half of these fields for 64-bit guests. The usual effect was that a guest which used signals would crash on return from a signal unless it was lucky enough to take it while the PC was in the low 4GB of the address space. In particular, Debian /bin/dash and /bin/bash would segfault after executing external commands. Use abi_ulong, which is the type these fields all have in the __siginfo_t struct.

2020-11-10linux-user/sparc: Correct set/get_context handling of fp and i7Peter Maydell1-25/+22
Because QEMU's user-mode emulation just directly accesses guest CPU state, for SPARC the guest register window state is not the same in the sparc64_get_context() and sparc64_set_context() functions as it is for the real kernel's versions of those functions. Specifically, for the kernel it has saved the user space state such that the O* registers go into a pt_regs struct as UREG_I*, and the I* registers have been spilled onto the userspace stack. For QEMU, we haven't done that, so the guest's O* registers are still in WREG_O* and the I* registers in WREG_I*. The code was already accessing the O* registers correctly for QEMU, but had copied the kernel code for accessing the I* registers off the userspace stack. Replace this with direct accesses to fp and i7 in the CPU state, and add a comment explaining why we differ from the kernel code here. This fix is sufficient to get bash to a shell prompt.

2020-11-10linux-user/sparc: Fix errors in target_ucontext structuresPeter Maydell1-4/+9
The various structs that make up the SPARC target_ucontext had some errors: * target structures must not include fields which are host pointers, which might be the wrong size. These should be abi_ulong instead * because we don't have the 'long double' part of the mcfpu_fregs union in our version of the target_mc_fpu struct, we need to manually force it to be 16-aligned In particular, the lack of 16-alignment caused sparc64_get_context() and sparc64_set_context() to read and write all the registers at the wrong offset, which triggered a guest glibc stack check in siglongjmp: *** longjmp causes uninitialized stack frame ***: terminated when trying to run bash.

This patch introduces missing target types ('target_flag_t', 'target_cc_t', 'target_speed_t') in a few 'termibts.h' header files.

2020-08-27linux-user: Add strace support for printing arguments of syscalls used to ↵Filip Bozuta1-2/+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.

2019-04-18qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster1-1/+1
CPUClass method dump_statistics() takes an fprintf()-like callback and a FILE * to pass to it. Most callers pass fprintf() and stderr. log_cpu_state() passes fprintf() and qemu_log_file. hmp_info_registers() passes monitor_fprintf() and the current monitor cast to FILE *. monitor_fprintf() casts it right back, and is otherwise identical to monitor_printf(). The callback gets passed around a lot, which is tiresome. The type-punning around monitor_fprintf() is ugly. Drop the callback, and call qemu_fprintf() instead. Also gets rid of the type-punning, since qemu_fprintf() takes NULL instead of the current monitor cast to FILE *.

2018-11-15linux-user/sparc/signal.c: Remove dead codePeter Maydell1-8/+8
Coverity complains (CID 1390847) about some dead code in do_sigreturn(). This is an if (err) clause that can never be true, copied from the kernel (where __get_user returns an error). The one code path that could report an error is in the currently commented-out pseudocode for handling FPU register restoring, so move the if into that comment (and fix the broken indent in the comment in the process). (The new position for the error check is also the semantically correct one -- we should not restore the signal mask from the signal frame if we get an error here, so the check must be done before set_sigmask(), not after.)

2018-11-12linux-user: Don't call gdb_handlesig() before queue_signal()Peter Maydell1-12/+4
The CPU main-loop routines for linux-user generally call gdb_handlesig() when they're about to queue a SIGTRAP signal. This is wrong, because queue_signal() will cause us to pend a signal, and process_pending_signals() will then call gdb_handlesig() itself. So the effect is that we notify gdb of the SIGTRAP, and then if gdb says "OK, continue with signal X" we will incorrectly notify gdb of the signal X as well. We don't do this double-notify for anything else, only SIGTRAP. Remove this unnecessary and incorrect code from all the targets except for nios2 (whose main loop is doing something different and broken, and will be handled in a separate patch). This bug only manifests if the user responds to the reported SIGTRAP using "signal SIGFOO" rather than "continue"; since the latter is the overwhelmingly common thing to do after a breakpoint most people won't have hit this.

2018-05-11linux-user: update sparc/syscall_nr.h to linux header 4.16Laurent Vivier1-1/+31
And kill sys_aplib, add sys_sync_file_range: on sparc, since linux 2.6.17, aplib syscall has been replaced by sync_file_range syscall. (289eee6fa78e ["SPARC]: Wire up sys_sync_file_range() into syscall tables.") The syscall has been removed in linux v2.5.71 (6196166fad "[SPARC64]: Kill sys_aplib.")

2016-09-21linux-user: Use correct target SHMLBA in shmat()Peter Maydell1-0/+16
The shmat() handling needs to do target-specific handling of the attach address for shmat(): * if the SHM_RND flag is passed, the address is rounded down to a SHMLBA boundary * if SHM_RND is not passed, then the call is failed EINVAL if the address is not a multiple of SHMLBA Since SHMLBA is target-specific, we need to do this checking and rounding in QEMU and can't leave it up to the host syscall. Allow targets to define TARGET_FORCE_SHMLBA and provide a target_shmlba() function if appropriate, and update do_shmat() to honour them.
