scsi: qla2xxx: Null out freed pointers in qla2x00_mem_alloc() error path<\/p>\n
When qla2x00_mem_alloc() fails, qla2x00_probe_one() jumps to
\nprobe_hw_failed and calls qla2x00_mem_free(). Several error labels in
\nqla2x00_mem_alloc() freed adapter members (elsrej.c, purex_dma_pool,
\nflt, sfp_data, loop_id_map, async_pd, sf_init_cb, ex_init_cb, npiv_info)
\nbut left the pointers dangling. qla2x00_mem_free() then freed them a
\nsecond time. Worse, for the dma_pool members it issued
\ndma_pool_free(ha->s_dma_pool, …) after s_dma_pool had already been
\ndestroyed and set to NULL at fail_s_dma_pool, dereferencing a NULL pool.<\/p>\n
Clear each freed pointer (and its DMA handle) in the error labels so the
\nsubsequent qla2x00_mem_free() skips them.<\/p>\n","protected":false},"excerpt":{"rendered":"
