for an example of a library wanting to cache an open fd ... and failing miserably at protecting itself from the application closing its fd read: http://bugzilla.padl.com/show_bug.cgi?id=304 http://bugzilla.padl.com/show_bug.cgi?id=305 basically libnss-ldap is trying to use getsockname/getpeername to prove that an fd belongs to it. the failure modes are quite delightful. -dean - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
