This is the second approach at Strace Test. Basically Strace test runs a lot of LTP tests. The difference is that it calls traces the system calls from the LTP tests and calls them again with improper values. That adds an extra kick. I think Strace Test might be the fastest general purpose kernel crasher there is. In this version, I added some new improper values to try, based on some source code that Dave Jones wrote. The other effective change was to start multiple instance of the same test at the same time. That helps trigger race conditions. I tried testing on 2.4 and it was really stable. On 2.6, I was able to simulate an SMP kernel using the preempt code and that helps locate race conditions. I wasn't able to test a 2.2 kernel but my guess is that it's pretty stable, especially with a UP kernel. http://67.113.20.209/strace_test-2.tar.gz Test Instructions (for i386) Create a test user Download and untar ltp (ltp.sf.net) Cd to ltp and `make -k` Untar strace_test cd strace_test && ./go_go.sh Enter the path to ltp Enter the test user regards, dan carpenter -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
