-stable review patch. If anyone has any objections, please let us know.
------------------
Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c and
forced by binary compatibility. UML/32bit breaks because of this - since it is
wise
enough to use PTRACE_OLDSETOPTIONS to be binary compatible with 2.4 host
kernels.
Until 2.6.17 (commit f0f2d6536e3515b5b1b7ae97dc8f176860c8c2ce) we had:
default:
return sys_ptrace(request, pid, addr, data);
Instead here we have:
case PTRACE_GET_THREAD_AREA:
case ...:
return sys_ptrace(request, pid, addr, data);
default:
return -EINVAL;
This change was a style change - when a case is added, it must be explicitly
tested this way. In this case, not enough testing was done.
