Description of problem:
Found a regression against kernel.org in RH kernels utrace based implementation
of ptrace(2).
Version-Release number of selected component (if applicable):
kernel-2.6.20-1.3045.fc7.x86_64
(on FC6 system)
How reproducible:
Always.
Steps to Reproduce:
1. gcc -o stopkills stopkills.c -Wall -ggdb3
2. ./stopkills
Actual results:
./stopkills: PTRACE_DETACH: No such process
Expected results:
(nothing; exit code 0)
Additional info:
ptrace (PTRACE_CONT, child_pid, NULL, (void *) SIGSTOP);
ptrace (PTRACE_DETACH, child_pid, NULL, NULL);
PTRACE_DETACH fails by ESRCH on the utrace kernels.
