From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: The ptrace security fixes were discovered to be buggy: they prevent ptrace()ing a process which has called setuid(). This makes it very difficult, for instance, to debug an Apache httpd server. Version-Release number of selected component (if applicable): kernel-2.4.9-e.16 How reproducible: Always Steps to Reproduce: 1. service httpd start 2. ps axf # and find an httpd child 3. strace -p <thepid> Actual Results: attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted Expected Results: normal strace output. Additional info: This was fixed in some of the kernel updates for RHL, e.g. kernel-2.4.20-13.9 works correctly.
fixed for U3
