2021-09-13linux-user: Split linux-user internals out of qemu.hPeter Maydell
qemu.h is included in various non-linux-user files (which mostly want the TaskState struct and the functions for doing usermode access to guest addresses like lock_user(), unlock_user(), get_user*(), etc). Split out the parts that are only used in linux-user itself into a new user-internals.h. This leaves qemu.h with basically three things: * the definition of the TaskState struct * the user-access functions and macros * do_brk() all of which are needed by code outside linux-user that includes qemu.h. The addition of all the extra #include lines was done with sed -i '/include.*qemu\.h/a #include "user-internals.h"' $(git grep -l 'include.*qemu\.h' linux-user) (and then undoing the change to fpa11.h).

2020-11-11linux-user: Correct definition of stack_tLemonBoy
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.

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

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 Armbruster
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 *.

2018-11-12linux-user: Don't call gdb_handlesig() before queue_signal()Peter Maydell
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.

2018-04-30linux-user: create a dummy per arch cpu_loop.cLaurent Vivier
Create a cpu_loop-common.h for future use by these new files and use it in the existing main.c Introduce target_cpu_copy_regs(): declare the function in cpu_loop-common.h and an empty function for each target, to move all the cpu_loop prologues to this function.

2018-04-30linux-user: define TARGET_ARCH_HAS_SETUP_FRAMELaurent Vivier
Instead of calling setup_frame() conditionally to a list of known targets, define TARGET_ARCH_HAS_SETUP_FRAME if the target provides the function and call it only if the macro is defined.

Instead of a sequence of "#if ... #endif" move the selection to a function in linux-user/*/target_elf.h We can't add them in linux-user/*/target_cpu.h because we will need to include "elf.h" to use ELF flags with eflags, and including "elf.h" in "target_cpu.h" introduces some conflicts in elfload.c Suggested-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20180220173307.25125-2-laurent@vivier.eu>
