I've been getting the same problem lately. I worked around it locally with
this patch:
--- a/libbb/change_identity.c
+++ b/libbb/change_identity.c
@@ -35,7 +35,9 @@ void FAST_FUNC change_identity(const struct passwd *pw)
{
if (initgroups(pw->pw_name, pw->pw_gid) == -1)
bb_perror_msg_and_die("can't set groups");
+#ifndef __ANDROID__
endgrent(); /* helps to close a fd used internally by libc */
+#endif
xsetgid(pw->pw_gid);
xsetuid(pw->pw_uid);
}
but it seemed a bit inelegant to me. But, that that line seems to have been
added to work around a specific libc issue, maybe it's not to ugly to
remove it on libcs that don't have that issue.
