good evening, i stumbled over some funny issue when trying windirstat (like KDirStat) with wine.
after running that tool for a while my system rebooted. i could reproduce this with every run. after some deep investigation (i thought i had stability issues with my system and spent more than an hour on this) i found out, that the reboot is being triggered by iTCO_wdt ( /dev/watchdog ) this is how to reproduce: - be root - cat /dev/watchdog or dd if=/dev/watchdog of=/dev/zero bs=1 count=1 or ..... - wait one minute........ *reboot*! i have heard 2 opinions for now (contacted the author and also discussed on wine-devel ) that this should be expected behaviour. being sysadmin quite a while, i cannot believe that (accidentally) reading a device file (being root or not - what does that matter) triggers a system reboot. ok - when i`m root , i shouldn`t do stupid things and be careful, but i thought reading/crawling trough a filesystem (r/o, btw.) with some tool which is built to do exactly this wasn`t so stupid - even from within wine. think of an admin writing a quick&dirty script for intrusion detection (find / -exec md5sum {} \; >/tmp/need-no-tripwire) and forgetting to exclude /dev, /sys or /proc appropriately...... think of someone exporting "/" via samba (readonly) and then navigating trough the /dev directory.... stupid? i don`t think so.....i have seen worse things...... :) should someone get punished by an accidental system reboot and should he need to spend his time on this to investigate why this happens? i`d wish there would be some fence around this or iTCO_wdt /dev/watchdog not being active after a default desktop installation. i`d be interested if i`m the only one who thinks this is strange/dangerous behaviour. regards roland _____________________________________________________________________ Der WEB.DE SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen! http://smartsurfer.web.de/?mc=100071&distributionid=000000000066 - 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/
