Lai Jiangshan b654a0fbd3 Merge pull request #42 from gao-feng/free 
fix possible access memory after free
 2016-02-01 10:56:40 +08:00
Gao feng db33f31dc1 fix possible access memory after free 
For tasks created by clone_VM, they share the memory with parent,
so when parent frees the stack, children may still access to this
stack. so don't free stack when children is still using the stack.

Gao feng c14737f39c do not close pipe in write side 
hyper_container_stage0 shares fd table with init, right now stage0
may close pipe before init read the pipe. this will cause container
fail to start.

WANG Chao 4b6375a4a4 Use configure script to check setns function 
I happen to find out on centos6.7, glibc-headers does have SYS_setns
defined, but previous release doesn't.

It's better to use configure script to check setns function.

WANG Chao ee697391d6 define setns syscall wrapper to fix build issue 
For example on centos6.x, glibc doesn't contain setns syscall wrapper,
but kernel has setns. We can write a wrapper to simulate the glibc
behavior to fix compile issue.

NOTE: In such case, we will need kernel-headers to get syscall number.
