2019-07-19linux-user: fix to handle variably sized SIOCGSTAMP with new kernelsDaniel P. Berrangé
The SIOCGSTAMP symbol was previously defined in the asm-generic/sockios.h header file. QEMU sees that header indirectly via sys/socket.h In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115 the asm-generic/sockios.h header no longer defines SIOCGSTAMP. Instead it provides only SIOCGSTAMP_OLD, which only uses a 32-bit time_t on 32-bit architectures. The linux/sockios.h header then defines SIOCGSTAMP using either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even on 32-bit architectures To cope with this we must now convert the old and new type from the target to the host one.

2019-07-02linux-user: Add support for translation of statx() syscallAleksandar Rikalo
Implement support for translation of system call statx(). The implementation is based on "best effort" approach: if host is capable of executing statx(), host statx() is used. If not, the implementation includes invoking a more mature system call fstatat() on the host side to achieve as close as possible functionality. Support for statx() in kernel and glibc was, however, introduced at different points of time (the difference is more than a year): - kernel: Linux 4.11 (30 April 2017) - glibc: glibc 2.28 (1 Aug 2018) In this patch, the availability of statx() support is established via __NR_statx (if it is defined, statx() is considered available). This coincedes with statx() introduction in kernel. However, the structure statx definition may not be available in any header for hosts with glibc older than 2.28 (and it is, by design, to be defined in one of glibc headers), even though the full statx() functionality may be supported in kernel. Hence, a structure "target_statx" is defined in this patch, to remove that dependency on glibc headers, and to use statx() functionality as soon as the host kernel is capable of supporting it. Such statx structure definition is used for both target and host structures statx (of course, this doesn't mean the endian arrangement is the same on target and host - the endian conversion is done in all necessary cases).

2019-06-24linux-user: emulate msgsnd(), msgrcv() and semtimedop()Laurent Vivier
When we have updated kernel headers to 5.2-rc1 we have introduced new syscall numbers that can be not supported by older kernels and fail with ENOSYS while the guest emulation succeeded before because the syscalls were emulated with ipc(). This patch fixes the problem by using ipc() if the new syscall returns ENOSYS.

2019-05-24linux-user: Pass through nanosecond timestamp components for stat syscallsChen-Yu Tsai
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.

Add support for getting and setting extended private flags of a network device via SIOCSIFPFLAGS and SIOCGIFPFLAGS ioctls. The ioctl numeric values are platform-independent and determined by the file include/uapi/linux/sockios.h in Linux kernel source code: #define SIOCSIFPFLAGS 0x8934 #define SIOCGIFPFLAGS 0x8935 These ioctls get (or set) the field ifr_flags of type short in the structure ifreq. Such functionality is achieved in QEMU by using MK_STRUCT() and MK_PTR() macros with an appropriate argument, as it was done for existing similar cases.

2018-05-03linux-user: remove useless padding in flock64 structureLaurent Vivier
Since commit 8efb2ed5ec ("linux-user: Correct signedness of target_flock l_start and l_len fields"), flock64 structure uses abi_llong for l_start and l_len in place of "unsigned long long" this should force them to be aligned accordingly to the target rules. So we can remove the padding field and the QEMU_PACKED attribute. I have compared the result of the following program before and after the change: cat -> flock64_dump <<EOF p/d sizeof(struct target_flock64) p/d &((struct target_flock64 *)0)->l_type p/d &((struct target_flock64 *)0)->l_whence p/d &((struct target_flock64 *)0)->l_start p/d &((struct target_flock64 *)0)->l_len p/d &((struct target_flock64 *)0)->l_pid quit EOF for file in build/all/*-linux-user/qemu-* ; do echo $file gdb -batch -nx -x flock64_dump $file 2> /dev/null done The sizeof() changes because we remove the QEMU_PACKED. The new size is 32 (except for i386 and m68k) and this is the real size of "struct flock64" on the target architecture. The following architectures differ: aarch64_be, aarch64, alpha, armeb, arm, cris, hppa, nios2, or1k, riscv32, riscv64, s390x. For a subset of these architectures, I have checked with the following program the new structure is the correct one: #include <stdio.h> #define __USE_LARGEFILE64 #include <fcntl.h> int main(void) { printf("struct flock64 %d\n", sizeof(struct flock64)); printf("l_type %d\n", &((struct flock64 *)0)->l_type); printf("l_whence %d\n", &((struct flock64 *)0)->l_whence); printf("l_start %d\n", &((struct flock64 *)0)->l_start); printf("l_len %d\n", &((struct flock64 *)0)->l_len); printf("l_pid %d\n", &((struct flock64 *)0)->l_pid); } [I have checked aarch64, alpha, hppa, s390x] For ARM, the target_flock64 becomes the EABI definition, so we need to define the OABI one in place of the EABI one and use it when it is needed. I have also fixed the alignment value for sh4 (to align llong on 4 bytes) (see c2e3dee6e0 "linux-user: Define target alignment size") [We should check alignment properties for cris, nios2 and or1k] Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20180502215730.28162-1-laurent@vivier.eu>

Fix the mmap_flags translation table to translate MAP_HUGETLB between host and target architecture, and to drop MAP_STACK.

2017-11-07linux-user/hppa: Fix TARGET_MAP_TYPEHelge Deller

2017-11-07linux-user: Restrict usage of sa_restorerRichard Henderson
Reading and writing to an sa_restorer member that isn't supposed to exist corrupts user memory. Introduce TARGET_ARCH_HAS_SA_RESTORER, similar to the kernel's __ARCH_HAS_SA_RESTORER.

2017-10-17linux-user: Fix TARGET_MTIOCTOP/MTIOCGET/MTIOCPOS valuesPeter Maydell
The TARGET_MTIOCTOP/TARGET_MTIOCGET/TARGET_MTIOCPOS values were being defined in terms of host struct types, but these structures are such that their size might differ on different hosts. Switch to using a target struct definition instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2017-10-16linux-user: Fix target FS_IOC_GETFLAGS and FS_IOC_SETFLAGS numbersPeter Maydell
We were defining TARGET_FS_IOC_GETFLAGS and TARGET_FS_IOC_SETFLAGS using the host 'long' type in the size field, which meant that they had the wrong values if the host and guest had different sized longs. Switch to abi_long instead. This fixes a bug where these ioctls don't work on 32-bit guests on 64-bit hosts (and makes the LTP test 'setxattr03' pass where it did not previously.)

Since O_TMPFILE might differ between guest and host, add it to the bitmask_transtbl. While at it, fix the definitions of O_DIRECTORY etc which should arm32 according to kernel sources. This fixes open14 and openat03 ltp testcases. Fixes: https://bugs.launchpad.net/qemu/+bug/1709170
