690.0. "/dev/null permissions" by MUNDIS::MBACHMANN (MAIK BACHMANN @MFR) Mon Apr 24 1995 17:15

Hi there,



DCR150
OSF3.0B on Sable machine


When starting console by /sbin/init.d/consoled start
permissions of /dev/null are changed so that world cannot write onto
it any longer.
This is done by one of the background processes ( consoled or ENS ).

Workaround:

   vi /sbin/init.d/consoled

   goto end

   sleep 5
   chmod 666 /dev/null



Anyone seen this problem - an " official " patch or ....


Thanks  -  Maik

690.1	Have seen "very secure" /dev/null too !	EEMELI::SYVANEN		`Fri May 12 1995 01:11`	14
	>>Anyone seen this problem - an " official " patch or .... A customer of mine was also hit by this bug. I enabled audit subsystem to log fchmod() and chmod() calls and it really turned out that consoled was calling fchmod() and changed protection of /dev/null to 754 ! I'm also very interested of an official patch. Regards Tero
690.2		PBUNIX::pgb	And through the square window...	`Fri May 12 1995 13:55`	12
	Hi, Nowhere in the code do we do a chmod to 754 of any files, we do however chmod to 777, 774 and 644 in various places. All our chmods are to do with log and archive files (socket files too on OSF/1). Do you happen to have /dev/null specified as a log or archive directory path for any of your systems? Cheers, Phil
690.3	See it here too...	KAOOSC::boivin	Moi, j'viens du nord!	`Fri May 12 1995 16:33`	9
	Good day, I see the problem here too. I initially blamed DECinspect but the problem is still occuring after changing Inspect's check of /dev/null. I'm also interested in finding out who the culprit is (PCM or other) and getting a patch... Ed

	Maik, the problem is fixed in the latest V1.6 OSF kit. It has just been put on the net see note 2.LAST. Please try it out and confirm your problem is fixed. Cheers Simon...
690.7	Thats real good news - thanks	MUNDIS::MBACHMANN	MAIK BACHMANN @MFR	`Wed May 17 1995 10:38`	9
	Thanks a lot for the quick solution, I will try it here in Munich. When is the next "official" release planned ( layered products CDROM )????? Thanks - Maik
690.8	ASAP	ZEDAR::simon	Simon Jackson 830 x3879	`Wed May 17 1995 13:37`	9
	Maik, because this is really a maintainence release (plus a few new bits) we are planning to submit when the major problems which the kit is meant to fix are validated and the bugs reported are fixed. We hope this will be in 2-3 weeks. Obviously then is is down to when the CDROMS are generated for the platforms. Cheers Simon...
