Daniel P. Berrange 7b3c618ad0 io: fix stack allocation when sending of file descriptors ... When sending file descriptors over a socket, we have to allocate a data buffer to hold the FDs in the scmsghdr. Unfortunately we allocated the buffer on the stack inside an if () {} block, but called sendmsg() outside the block. So the stack bytes holding the FDs were liable to be overwritten with other data. By luck this was not a problem when sending 1 FD, but if sending 2 or more then it would fail. The fix is to simply move the variables outside the nested 'if' block. To keep valgrind quiet we also zero-initialize the 'control' buffer. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>		2015-12-23 10:53:03 +00:00
