-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.
