The lxc_controller has a structure that's keeping its internal state, including so called handshakeFd which is the write end of a pipe that's used to signal to the LXC driver that the container is set up and ready to run. However, the struct member is not initialized to -1, so if anything fails before it is set then the virLXCControllerFree() function tries to close FD 0 (stdin).Signed-off-by: Michal Privoznik <mpriv...@redhat.com> --- src/lxc/lxc_controller.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
