I put together a quick patch that implements dropping of the root privileges. There are few issues. One is that ptp4l is not able to respond to pmc running under root. pmc would have to chmod() or chown() it. Also, all sockets would probably have to be moved to a new directory owned by the user under which ptp4l is running. Would it make sense to support this in linuxptp? -- Miroslav Lichvar ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
