2020-08-27linux-user: Add missing termbits types and values definitionsFilip Bozuta
This patch introduces missing target types ('target_flag_t', 'target_cc_t', 'target_speed_t') in a few 'termibts.h' header files. Also, two missing values ('TARGET_IUTF8' and 'TARGET_EXTPROC') were also added. These values were also added in file 'syscall.c' in bitmask tables 'iflag_tbl[]' and 'lflag_tbl[]' which are used to convert values of 'struct termios' between target and host.

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.

2020-08-21meson: linux-userMarc-André Lureau
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 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.

Remove some dead code spotted by Coverity (CID 1009855, 1390854, 1390847). The underlying cause in all these cases is the same: QEMU's put_user operations can't result in errors, but the kernel's equivalent does. So when code was copied from the kernel signal-frame-setup/teardown code, checks on error flags that were needed in the kernel became dead code for us.

As reported by Cédric VINCENT: The syscall #123 on SH4 should be "TARGET_NR_cacheflush" instead of "TARGET_NR_modify_ldt" [1]. The only consequence of this misnaming is that many "Unsupported syscall" warnings are issued when emulating JIT compilers.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.
