It corresponds to "run" directory in Unix. With a tree-wide search, it was found that there are several cases where such a functionality is implemented so let's have one as a common utlity function. A notable feature of qemu_get_runtime_dir() is that it uses $XDG_RUNTIME_DIR if available. While the function is often called by executables which requires root privileges, it is still possible that they are called from a user without privilege to write the system runtime directory. In fact, I decided to write this patch when I ran virtiofsd in a Linux namespace created by a normal user and realized it tries to write the system runtime directory, not writable in this case. $XDG_RUNTIME_DIR should provide a writable directory in such cases. This function does not use qemu_get_local_state_dir() or its logic for Windows. Actually the implementation of qemu_get_local_state_dir() for Windows seems not right as it calls g_get_system_data_dirs(), which refers to $XDG_DATA_DIRS. In Unix terminology, it is basically "/usr/share", not "/var", which qemu_get_local_state_dir() is intended to provide. Instead, this function try to use the following in order: - $XDG_RUNTIME_DIR - LocalAppData folder - get_relocated_path(CONFIG_QEMU_LOCALSTATEDIR "/run") This function does not use g_get_user_runtime_dir() either as it falls back to g_get_user_cache_dir() when $XDG_DATA_DIRS is not available. In the case, we rather use: get_relocated_path(CONFIG_QEMU_LOCALSTATEDIR "/run") Signed-off-by: Akihiko Odaki Message-Id: <20230921075425.16738-2-akihiko.odaki@daynix.com> --- include/qemu/osdep.h | 12 ++++++++++++ util/oslib-posix.c | 11 +++++++++++ util/oslib-win32.c | 26 ++++++++++++++++++++++++++ 3 files changed, 49 insertions(+) diff --git a/include/qemu/osdep.h b/include/qemu/osdep.h index 191916f38e6d..fe8609fc1375 100644 --- a/include/qemu/osdep.h +++ b/include/qemu/osdep.h @@ -670,6 +670,18 @@ void qemu_set_cloexec(int fd); */ char *qemu_get_local_state_dir(void); =20 +/** + * qemu_get_runtime_dir: + * + * Return a dynamically allocated directory path that is appropriate for s= toring + * runtime files.
