Description Soumya Koduri 2018-11-11 17:30:46 UTC

Description of problem:

afr_open() stores fd reference in local->cont.open structure. But in the callback function "afr_open_ftruncate_cbk" ( when openflags contain 'O_TRUNC' set), we reference local->fd in AFR_STACK_UNWIND resulting in error or crash.
