I think that the Amanda problem was actually with that patch, and not with mine. I was sent a test program to illustrate the break, and ran it on the unpatched inetd and then again after applying my patch, and the signal masks in the child were the same in each case (no signals blocked). We have a number of clients running our firewalls with my patch applied to inetd and no-one has reported any problems yet. The standard disclaimers apply, of course ;-). The idea of using a pipe to hold flags for signals to be processed was not mine; Don Lewis and Warner Losh suggested it to me, so they should take much of the credit for the patch. -- Dr Graham Wheeler E-mail: gram@cdsec.com Citadel Data Security Phone: +27(21)423-6065/6/7 Firewalls/Virtual Private Networks Fax: +27(21)24-3656 Internet/Intranet Network Specialists Data Security Products WWW: http://www.cdsec.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
