>Number: 5212 >Category: kern >Synopsis: nullfs crashes under several situations >Confidential: no >Severity: serious >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Wed Dec 3 21:20:01 PST 1997 >Last-Modified: >Originator: Hoffmann Yen-Wei Liu >Organization: Sinanet.com, Inc. >Release: FreeBSD 2.2.5-RELEASE i386 >Environment: AMD K6/200, 64MB RAM, PCI motherboard. FreeBSD 2.2.5 (both stock and customized kernels). >Description: Some operations on nullfs would cause segmentation fault or kernel panic. >How-To-Repeat: 1) when "tail"ing a file on nullfs, it usually gets seg fault, or kernel panic. (This happens both on 2.2.2 and 2.2.5, even with stock kernel.) 2) when nullfs is mounted, to remount it would cause kernel panic. (This happens, at least, on 2.2.5, even with stock kernel.) >Fix: 1) I compiled a copy of "tail" from GNU textutil and it worked. 2) Avoid using "mount -a" when nullfs is mounted. Or avoid using nullfs.8-( _________________________________________________________ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com >Audit-Trail: >Unformatted:
