2023-10-18linux-user/mips: fix abort on integer overflowMikulas Patocka1-1/+3
QEMU mips userspace emulation crashes with "qemu: unhandled CPU exception 0x15 - aborting" when one of the integer arithmetic instructions detects an overflow. This patch fixes it so that it delivers SIGFPE with FPE_INTOVF instead.

2023-03-30linux-user/mips: Use P5600 as default CPU to run NaN2008 ELF binariesPhilippe Mathieu-Daudé1-0/+3
Per the release 6.06 revision history: 5.03 August 21, 2013 • ABS2008 and NAN2008 fields of Table 5.7 “FCSR RegisterField Descriptions” were optional in release 3 and could be R/W, but as of release 5 are required, read-only, and preset by hardware. The P5600 core implements the release 5, and has the ABS2008 and NAN2008 bits set in CP1_fcr31. Therefore it is able to run ELF binaries compiled with EF_MIPS_NAN2008, such the CIP United Debian NaN2008 distribution: http://repo.oss.cipunited.com/mipsel-nan2008/README.txt In order to run such compiled binaries, select by default the P5600 core when the ELF 'MIPS_NAN2008' flag is set.

2021-09-13linux-user: Split linux-user internals out of qemu.hPeter Maydell2-0/+2
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).

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].

2020-08-27linux-user: Add missing termbits types and values definitionsFilip Bozuta1-6/+11
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 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.
