2019-06-12semihosting: split console_out into string and char versionsAlex Bennée1-3/+28
This is ostensibly to avoid the weirdness of len looking like it might come from a guest and sometimes being used. While we are at it fix up the error checking for the arm-linux-user implementation of the API which got flagged up by Coverity (CID 1401700). Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

Other accelerators have their own headers: sysemu/hax.h, sysemu/hvf.h, sysemu/kvm.h, sysemu/whpx.h. Only tcg_enabled() & friends sit in qemu-common.h. This necessitates inclusion of qemu-common.h into headers, which is against the rules spelled out in qemu-common.h's file comment.

2019-05-26linux-user: fix __NR_semtimedop undeclared errorLaurent Vivier1-8/+16
In current code, __NR_msgrcv and__NR_semtimedop are supposed to be defined if __NR_msgsnd is defined. But linux headers 5.2-rc1 for MIPS define __NR_msgsnd without defining __NR_semtimedop and it breaks the QEMU build. __NR_semtimedop is defined in asm-mips/unistd_n64.h and asm-mips/unistd_n32.h but not in asm-mips/unistd_o32.h. Commit d9cb4336159a ("linux headers: update against Linux 5.2-rc1") has updated asm-mips/unistd_o32.h and added __NR_msgsnd but not __NR_semtimedop. It introduces __NR_semtimedop_time64 instead. This patch fixes the problem by checking for each __NR_XXX symbol before defining the corresponding syscall.

2019-05-24linux-user: Pass through nanosecond timestamp components for stat syscallsChen-Yu Tsai2-18/+50
Since Linux 2.6 the stat syscalls have mostly supported nanosecond components for each of the file-related timestamps. QEMU user mode emulation currently does not pass through the nanosecond portion of the timestamp, even when the host system fills in the value. This results in a mismatch when run on subsecond resolution filesystems such as ext4 or XFS. An example of this leading to inconsistency is cross-debootstraping a full desktop root filesystem of Debian Buster. Recent versions of fontconfig store the full timestamp (instead of just the second portion) of the directory in its per-directory cache file, and checks this against the directory to see if the cache is up-to-date. With QEMU user mode emulation, the timestamp stored is incorrect, and upon booting the rootfs natively, fontconfig discovers the mismatch, and proceeds to rebuild the cache on the comparatively slow machine (low-power ARM vs x86). This stalls the first attempt to open whatever application that incorporates fontconfig. This patch renames the "unused" padding trailing each timestamp element to its nanosecond counterpart name if such an element exists in the kernel sources for the given platform. Not all do. Then have the syscall wrapper fill in the nanosecond portion if the host supports it, as specified by the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros. Recent versions of glibc only use stat64 and newfstatat syscalls on 32-bit and 64-bit platforms respectively. The changes in this patch were tested by directly calling the stat, stat64 and newfstatat syscalls directly, in addition to the glibc wrapper, on arm and aarch64 little endian targets.

2019-05-22linux-user: Sanitize interp_info and, for mips only, init field fp_abiDaniel Santos1-0/+5
Sanitize interp_info structure in load_elf_binary() and, for MIPS only, init its field fp_abi to MIPS_ABI_FP_UNKNOWN. This fixes appearances of "Unexpected FPU mode" message in some MIPS use cases. Currently, this bug is a complete stopper for some MIPS binaries. In load_elf_binary(), struct image_info interp_info is used without being properly initialized. One result is that when the ELF's program header doesn't contain an entry for the ABI flags, then the value of the struct image_info's fp_abi field is set to whatever happened to be in stack memory at the time. Backporting to 4.0 and, if possible, to 3.1 is recommended.

2019-05-22linux-user: Fix support for SIOCATMARK and SIOCGPGRP ioctls for xtensaAleksandar Markovic1-1/+2
Fix support for the SIOCATMARK and SIOCGPGRP ioctls for xtensa by correcting corresponding macro definition. Values for TARGET_SIOCATMARK and TARGET_SIOCGPGRP are determined by Linux kernel. Following relevant lines (obtained by grep) are from the kernel source tree: arch/ia64/include/uapi/asm/sockios.h:#define SIOCATMARK 0x8905 arch/mips/include/uapi/asm/sockios.h:#define SIOCATMARK _IOR('s', 7, int) arch/parisc/include/uapi/asm/sockios.h:#define SIOCATMARK 0x8905 arch/sh/include/uapi/asm/sockios.h:#define SIOCATMARK _IOR('s', 7, int) arch/xtensa/include/uapi/asm/sockios.h:#define SIOCATMARK _IOR('s', 7, int) arch/alpha/include/uapi/asm/sockios.h:#define SIOCATMARK _IOR('s', 7, int) arch/sparc/include/uapi/asm/sockios.h:#define SIOCATMARK 0x8905 include/uapi/asm-generic/sockios.h:#define SIOCATMARK 0x8905 arch/ia64/include/uapi/asm/sockios.h:#define SIOCGPGRP 0x8904 arch/mips/include/uapi/asm/sockios.h:#define SIOCGPGRP _IOR('s', 9, pid_t) arch/parisc/include/uapi/asm/sockios.h:#define SIOCGPGRP 0x8904 arch/sh/include/uapi/asm/sockios.h:#define SIOCGPGRP _IOR('s', 9, pid_t) arch/xtensa/include/uapi/asm/sockios.h:#define SIOCGPGRP _IOR('s', 9, pid_t) arch/alpha/include/uapi/asm/sockios.h:#define SIOCGPGRP _IOR('s', 9, pid_t) arch/sparc/include/uapi/asm/sockios.h:#define SIOCGPGRP 0x8904 include/uapi/asm-generic/sockios.h:#define SIOCGPGRP 0x8904 It is visible from above that xtensa should have the same definitions as alpha, mips and sh4 already do. This patch brings QEMU to the accurate state wrt these two ioctls.

2019-05-22linux-user: add pseudo /proc/hardware for m68kLaurent Vivier1-1/+12
Debian console-setup uses /proc/hardware to guess the keyboard layout. If the file /proc/hardware cannot be opened, the installation fails. This patch adds a pseudo /proc/hardware file to report the model of the machine. Instead of reporting a known and fake model, it reports "qemu-m68k", which is true, and avoids to set the configuration for an Amiga/Apple/Atari and let the user to chose the good one.

2019-05-22linux-user: add pseudo /proc/cpuinfo for sparcLaurent Vivier1-1/+15
SPARC libc6 debian package wants to check the cpu level to be installed or not: WARNING: This machine has a SPARC V8 or earlier class processor. Debian lenny and later does not support such old hardware any longer. To avoid this, it only needs to know if the machine type is sun4u or sun4v, for that it reads the information from /proc/cpuinfo.

2019-05-13Clean up ill-advised or unusual header guardsMarkus Armbruster3-8/+8
Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions.

Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. scripts/clean-header-guards.pl can't tell, so it warns. Since we can avoid guard symbol reuse easily, do so: use guard symbol ${target^^}_${fname^^} for linux-user/$target/$fname, just like we did in commit a9c94277f0..3500385697.
