These patches have the following problems. If you can address these, I'll make sure they're committed. - they back out some of the time-related changes. - the linux_ioperm() emulation does not check for appropriate priviledges before succeeding. This would open a gaping security hole. Thanks, and sorry for taking so long to get back to you on them. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
