I installed your patch on my system. A pretty busy 150 user system and
everything seems to work great. It's an httpd, ftp, qmail, shell account,
firewall machine :)
Would be nice to see this as an option in the Linux kernel. Maybe in the
"development" area. I personally think having this will be a plus for Linux
because as far as I know such a patch exists for Solaris (I don't think
it's by SunSoft though, not sure). And this really should get rid of most
buffer overflow vulnerabilities. I tested the crontab bug and SIGSEGV'd
very nicely :)
Thanks for the great patch, I'll mail again if it breaks...
