Alexander Motin 5008399c14 Fix use-after-free in case of L2ARC prefetch failure. ... In case L2ARC read failed, l2arc_read_done() creates _different_ ZIO to read data from the original storage device. Unfortunately pointer to the failed ZIO remains in hdr->b_l1hdr.b_acb->acb_zio_head, and if some other read try to bump the ZIO priority, it will crash. The problem is reproducible by corrupting L2ARC content and reading some data with prefetch if l2arc_noprefetch tunable is changed to 0. With the default setting the issue is probably not reproducible now. MFC after: 2 weeks Sponsored by: iXsystems, Inc.		2019-11-28 18:28:35 +00:00
