Hi. Rob I checked your changes ( New header is created. lib/lsm.h) on _Tizen Emulator_ And ls puts right smack label with -Z option. But there is a minor issue regarding spacing and alignment.
For example, doing "toybox ls -alZ" There is no spacing between groupowner and smack label. Further, other conjuction of options with Z causes spacing or alignment issue. plz, check if you have time.

Speaking of which, here are some notes from yesterday (results already checked in) about banging on ls: ----- The S_ISLNK() stanza is an abomination. I realize that you need to do this, but let's be honest: this is a bug workaround for kernel problems stemming from the fact that these APIs haven't been updated since the 1990's. Either there should be a getfileconat() or fgetfilecon() should work on O_PATH filehandles. Why is |O_NOATIME commented out here? The man page says it was introduced in 2.6.8, git annotate says openat() was introduced 2.6.16 (which was 2006 and we depend on posix-2008...) Ah, I see: #ifdef __USE_GNU # define O_DIRECT 040000 /* Direct disk access. */ # define O_NOATIME 01000000 /* Do not set atime. */ # define O_PATH 010000000 /* Resolve pathname but do not open file. */ #endif Once again, the linux kernel is not a part of the gnu project and the glibc developers didn't get that. Right, easy to fix up in portability.h. And why does this have O_NONBLOCK? We're recursing down into directories using openat() without that. Does this mean something in an selinux or smack context? The label: and totals: behavior is funky. "ls -s" and "ls -sd *" differ, the first prints totals: the second doesn't because total: is only on contents of a directory - posix Fix fix fix... ----- And here are notes from Jose's socket update patch: I don't think this covers all the cases. What about symlink to a socket without -L, or symlink to a file we haven't got permission to open? In those cases we need the "follow symlink but do it by path because O_PATH is broken" version? Also, if O_PATH worked, we wouldn't need O_NONBLOCK to avoid triggering automounting. (Is automounting still a thing in 2015?) P.S. I pulled your "other fix" by taking the actual commit, see git f25d4954a786. Rob
