Dear Stephen.
I have some question restorecon api.
When I create file like that
$ touch "test<space enter>
newline"
that file doesn't work restorecon..
For example, Google docs app (com.google.android.apps.docs) create these
files(thumbnail file) like bellows.
/data/data/com.google.android.apps.docs/cache/diskCache/fetching/accountCache_1$
ls
thumbnail-510-384-d_downloaded_image_am9uZXNuNTUwOEBnbWFpbC5jb20tZGI6Mw==
_1404878698133
thumbnail-510-384-d_downloaded_image_am9uZXNuNTUwOEBnbWFpbC5jb20tZGI6NA==

(new line involve)
Before SELinux enable(Android JB version), these files would be unlabeled.
That files doesn't change when upgrade (JB -> KK(SELinux Enable) -> L OS)
because restorecon doesn't work these files(involve newline).
Restorecon api doesn't work because of lookup_common() method (ret will
return null!)
external/libselinux/src/android.c
static int restorecon_sb()
..
if (selabel_lookup(sehandle, &secontext, pathname, sb->st_mode) < 0)
return 0
..
// if input file name include "new line", i will be -1 because rc would be
PCRE_ERROR_NOMATCH!
external/libselinux/src/label_file.c
static spec_t *lookup_common()
..
if (i < 0 || strcmp(spec_arr[i].lr.ctx_raw, "<<none>>") == 0) {
/* No matching specification. */
errno = ENOENT;
goto finish;
}
..
What should I do?
Please help this issue.
Thanks.
