Hi
Attaching the patch for the testcase on PIDNS.
Assertion:
1. kill -9 1 from inside a container does not kill container
Steps:
a) create container
b) kill -9 1
c) Should not kill the containers
Test Result: Currently this is failing, which eventually be passed.
# ./pidns04
pid_namespace4 0 INFO : PIDNS test is running inside container
pid_namespace4 1 FAIL : Container init is killed by SIGKILL !!!
pid_namespace4 2 FAIL : Container init pid got killed by signal 9
Regards
Veerendra C

+* Description:
+* The pidns04.c testcase builds into the ltp framework to verify
+* the basic functionality of PID Namespace.
+*
+* Verify that:
+* 1. When parent clone a process with flag CLONE_NEWPID, the process ID of
+* child should be one.
+*
+* 2. When parent clone a process with flag CLONE_NEWPID, the parent process ID
+* of should be zero.
+*
+* 3. The container init process (one), should not get killed by the SIGKILL in
+* the childNS
+*
+* Total Tests:
+*
+* Test Name: pidns04
+*
+* Test Assertion & Strategy:
+*
+* From main() clone a new child process with passing the clone_flag as
+* CLONE_NEWPID.
+* The container init, should not get killed by the SIGKILL inside the child NS.
+* Usage: <for command-line>
+* pidns04
