2019-05-24hw/arm: Use object_initialize_child for correct reference countingPhilippe Mathieu-Daudé
As explained in commit aff39be0ed97: Both functions, object_initialize() and object_property_add_child() increase the reference counter of the new object, so one of the references has to be dropped afterwards to get the reference counting right. Otherwise the child object will not be properly cleaned up when the parent gets destroyed. Thus let's use now object_initialize_child() instead to get the reference counting here right. This patch was generated using the following Coccinelle script (with a bit of manual fix-up for overly long lines): @use_object_initialize_child@ expression parent_obj; expression child_ptr; expression child_name; expression child_type; expression child_size; expression errp; @@ ( - object_initialize(child_ptr, child_size, child_type); + object_initialize_child(parent_obj, child_name, child_ptr, child_size, + child_type, &error_abort, NULL); ... when != parent_obj - object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), NULL); ... ?- object_unref(OBJECT(child_ptr)); | - object_initialize(child_ptr, child_size, child_type); + object_initialize_child(parent_obj, child_name, child_ptr, child_size, + child_type, errp, NULL); ... when != parent_obj - object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp); ... ?- object_unref(OBJECT(child_ptr)); ) @use_sysbus_init_child_obj@ expression parent_obj; expression dev; expression child_ptr; expression child_name; expression child_type; expression child_size; expression errp; @@ ( - object_initialize_child(parent_obj, child_name, child_ptr, child_size, - child_type, errp, NULL); + sysbus_init_child_obj(parent_obj, child_name, child_ptr, child_size, + child_type); ... - qdev_set_parent_bus(DEVICE(child_ptr), sysbus_get_default()); | - object_initialize_child(parent_obj, child_name, child_ptr, child_size, - child_type, errp, NULL); + sysbus_init_child_obj(parent_obj, child_name, child_ptr, child_size, + child_type); - dev = DEVICE(child_ptr); - qdev_set_parent_bus(dev, sysbus_get_default()); ) While the object_initialize() function doesn't take an 'Error *errp' argument, the object_initialize_child() does.

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.

The ICC_CTLR_EL3 register includes some bits which are aliases of bits in the ICC_CTLR_EL1(S) and (NS) registers. QEMU chooses to keep those bits in the cs->icc_ctlr_el1[] struct fields.

2019-05-23hw/nvram/fw_cfg: Store 'reboot-timeout' as little endianLi Qiang
The current codebase is not specific about the endianess of the fw_cfg 'file' entry 'reboot-timeout'. Per docs/specs/fw_cfg.txt: === All Other Data Items === Please consult the QEMU source for the most up-to-date and authoritative list of selector keys and their respective items' purpose, format and writeability. Checking the git history, this code was introduced in commit ac05f3492421, very similar to commit 3d3b8303c6f8 for the 'boot-menu-wait' entry, which explicitely use little-endian. OVMF consumes 'boot-menu-wait' as little-endian, however it does not consume 'reboot-timeout'. Regarding the git history and OVMF use, we choose to explicit 'reboot-timeout' endianess as little-endian.

Currently, fw_cfg_test uses one QTestState for every test case. This will add all command lines for every test case and this is unnecessary.
