For UFS, the\ncrypto private data and pointers are stored as part of the ufs_hba's\ndata structure 'struct ufs_hba::crypto_profile'. This structure is\nallocated as part of the underlying ufshcd and therefore Scsi_host\nallocation.\n\nDuring driver release or during error handling in ufshcd_pltfrm_init(),\nthis structure is released as part of ufshcd_dealloc_host() before the\n(platform-) device associated with the crypto call above is released.\nOnce this device is released, the crypto cleanup code will run, using\nthe just-released 'struct ufs_hba::crypto_profile'. This causes a\nuse-after-free situation:\n\n Call trace:\n kfree+0x60/0x2d8 (P)\n kvfree+0x44/0x60\n blk_crypto_profile_destroy_callback+0x28/0x70\n devm_action_release+0x1c/0x30\n release_nodes+0x6c/0x108\n devres_release_all+0x98/0x100\n device_unbind_cleanup+0x20/0x70\n really_probe+0x218/0x2d0\n\nIn other words, the initialisation code flow is:\n\n platform-device probe\n ufshcd_pltfrm_init()\n ufshcd_alloc_host()\n scsi_host_alloc()\n allocation of struct ufs_hba\n creation of scsi-host devices\n devm_blk_crypto_profile_init()\n devm registration of cleanup handler using platform-device\n\nand during error handling of ufshcd_pltfrm_init() or during driver\nremoval:\n\n ufshcd_dealloc_host()\n scsi_host_put()\n put_device(scsi-host)\n release of struct ufs_hba\n put_device(platform-device)\n crypto cleanup handler\n\nTo fix this use-after free, change ufshcd_alloc_host() to register a\ndevres action to automatically cleanup the underlying SCSI device on\nufshcd destruction, without requiring explicit calls to\nufshcd_dealloc_host(). This way:\n\n * the crypto profile and all other ufs_hba-owned resources are\n destroyed before SCSI (as they've been registered after)\n * a memleak is plugged in tc-dwc-g210-pci.c remove() as a\n side-effect\n * EXPORT_SYMBOL_GPL(ufshcd_dealloc_host) can be removed fully as\n it's not needed anymore\n * no future drivers using ufshcd_alloc_host() could ever forget\n adding the cleanup" } ],
