What was changed in the X86 ptrace to fix it? I think that the work must be done in the stack layout on ptracing (read th= e=20 handle_trap() function for what UML does). But also see this URL:=20 http://perso.wanadoo.fr/laurent.vivier/UML/ One of the nice thing of those patches is that if you implement something=20 similar (which is a lot easier IMHO) you don't need to be able to change=20 system call numbers. --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
