That security label genrally doesn't +allow sharing of files? Then passing the vreated file descriptor +to the client application fails with EPERM. + +To allow file descriptors to be tagged with a security +label that allows clients to receive and use it, that +patch introduce the use of the environment variable +XDG_RUNTIMESHARE_DIR that takes precedence over +XDG_RUNTIME_DIR whe, creating anonymous file is needed. + +A correct setting of the shared directory using Smack's +transmute mechanism allows set up file tag for sharing. + +This patch was submitted upstream for discussion but +was rejected with the following reason (IIRC): "the +function 'os_create_anonymous_file' and the sharing +are obsolete and should not be used anymore. IVI was +requiring it but newer version don't use it". Halas, +even aligned with latest versions of IVI-shell and weston, +the patch is needed. Because of its simplicity, it can +remain maintained locally out of mainstream in the wait +of further investigations. + +Signed-off-by: José Bollo <jose.bollo@iot.bzh> +--- + shared/os-compatibility.c | 1 + + 1 file changed, 1 insertion(+) + +diff --git a/shared/os-compatibility.c b/shared/os-compatibility.c +index e19fb61b..7e93e818 100644 +--- a/shared/os-compatibility.c ++++ b/shared/os-compatibility.c +@@ -157,6 +157,8 @@ os_create_anonymous_file(off_t size) + int fd; + int ret; + +- path = getenv("XDG_RUNTIME_DIR"); ++ path = getenv("XDG_RUNTIMESHARE_DIR"); ++ if (!path) ++ path = getenv("XDG_RUNTIME_DIR"); + if (!path) { + errno = ENOENT; +-- +2.13.6 + diff --git a/meta-agl-profile-graphical/recipes-graphics/wayland/weston_2.0.0.bbappend b/meta-agl-profile-graphical/recipes-graphics/wayland/weston_2.0.0.bbappend index fe1e1a11f..c0a301ec1 100644 --- a/meta-agl-profile-graphical/recipes-graphics/wayland/weston_2.0.0.bbappend +++ b/meta-agl-profile-graphical/recipes-graphics/wayland/weston_2.0.0.bbappend @@ -21,6 +21,7 @@ SRC_URI_append = "\ file://0017-ivi-shell-register-ivi_layout_interface.patch \ file://0018-compositor-add-output-type-to-weston_output.patch \ file://0019-compositor-drm-introduce-drm_get_dmafd_from_view.patch \ + file://use-XDG_RUNTIMESHARE_DIR.patch \ " EXTRA_OECONF_append = " --enable-sys-uid" |
