2017-10-12USB: uas: fix bug in handling of alternate settingsAlan Stern
commit 786de92b3cb26012d3d0f00ee37adf14527f35c4 upstream. The uas driver has a subtle bug in the way it handles alternate settings. The uas_find_uas_alt_setting() routine returns an altsetting value (the bAlternateSetting number in the descriptor), but uas_use_uas_driver() then treats that value as an index to the intf->altsetting array, which it isn't. Normally this doesn't cause any problems because the various alternate settings have bAlternateSetting values 0, 1, 2, ..., so the value is equal to the index in the array. But this is not guaranteed, and Andrey Konovalov used the syzkaller fuzzer with KASAN to get a slab-out-of-bounds error by violating this assumption. This patch fixes the bug by making uas_find_uas_alt_setting() return a pointer to the altsetting entry rather than either the value or the index. Pointers are less subject to misinterpretation.

2017-10-12usb-storage: fix bogus hardware error messages for ATA pass-thru devicesAlan Stern
commit a4fd4a724d6c30ad671046d83be2e9be2f11d275 upstream. Ever since commit a621bac3044e ("scsi_lib: correctly retry failed zero length REQ_TYPE_FS commands"), people have been getting bogus error messages for USB disk drives using ATA pass-thru. For example: [ 1344.880193] sd 6:0:0:0: [sdb] Attached SCSI disk [ 1345.069152] sd 6:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE [ 1345.069159] sd 6:0:0:0: [sdb] tag#0 Sense Key : Hardware Error [current] [descriptor] [ 1345.069162] sd 6:0:0:0: [sdb] tag#0 Add.

Other programs can also have this effect, such as those in smartmontools. I don't fully understand how that commit induced the SCSI core to log these error messages, but the underlying cause for them is code added to usb-storage by commit f1a0743bc0e7 ("USB: storage: When a device returns no sense data, call it a Hardware Error"). At the time it was necessary to do this, in order to prevent an infinite retry loop with some not-so-great mass storage devices. However, the ATA pass-thru protocol uses SCSI sense data to return command status values, and some devices always report Check Condition status for ATA pass-thru commands to ensure that the host retrieves the sense data, even if the command succeeded. This violates the USB mass-storage protocol (Check Condition status is supposed to mean the command failed), but we can't help that. This patch attempts to mitigate the problem of these bogus error reports by changing usb-storage. The HARDWARE ERROR sense key will be inserted only for commands that aren't ATA pass-thru. Thanks to Ewan Milne for pointing out that this mechanism was present in usb-storage. 8 years after writing it, I had completely forgotten its existence.

This is incorrect, without the scsi_change_queue_depth() call the slave's queue_depth defaults to 1, introducing a performance regression. This commit restores the call, fixing the performance regression.

2016-04-04mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macrosKirill A. Shutemov
PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE. This promise never materialized. And unlikely will. We have many places where PAGE_CACHE_SIZE assumed to be equal to PAGE_SIZE. And it's constant source of confusion on whether PAGE_CACHE_* or PAGE_* constant should be used in a particular case, especially on the border between fs and mm. Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much breakage to be doable. Let's stop pretending that pages in page cache are special. They are not. The changes are pretty straight-forward: - <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN}; - page_cache_get() -> get_page(); - page_cache_release() -> put_page(); This patch contains automated changes generated with coccinelle using script below. For some reason, coccinelle doesn't patch header files. I've called spatch for them manually. The only adjustment after coccinelle is revert of changes to PAGE_CAHCE_ALIGN definition: we are going to drop it later. There are few places in the code where coccinelle didn't reach. I'll fix them manually in a separate patch. Comments and documentation also will be addressed with the separate patch. virtual patch @@ expression E; @@ - E << (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ expression E; @@ - E >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ @@ - PAGE_CACHE_SHIFT + PAGE_SHIFT @@ @@ - PAGE_CACHE_SIZE + PAGE_SIZE @@ @@ - PAGE_CACHE_MASK + PAGE_MASK @@ expression E; @@ - PAGE_CACHE_ALIGN(E) + PAGE_ALIGN(E) @@ expression E; @@ - page_cache_get(E) + get_page(E) @@ expression E; @@ - page_cache_release(E) + put_page(E) Signed-off-by: Kirill A.

2015-07-22usb-storage: Add ignore-device quirk for gm12u320 based usb mini projectorsHans de Goede
Grain-media GM12U320 based devices are mini video projectors using USB for both power and video data transport. Their usb-storage interface is a virtual windows driver CD. The gm12u320 kms driver needs these interfaces to talk to the device and export it as framebuffer & kms dri device nodes, so make sure that the usb-storage driver does not bind to it.

2015-07-22usb-storage: ignore ZTE MF 823 card reader in mode 0x1225Oliver Neukum
This device automatically switches itself to another mode (0x1405) unless the specific access pattern of Windows is followed in its initial mode. That makes a dirty unmount of the internal storage devices inevitable if they are mounted. So the card reader of such a device should be ignored, lest an unclean removal become inevitable. This replaces an earlier patch that ignored all LUNs of this device. That patch was overly broad.

2015-05-10usb: storage: fix module reference for scsi hostAkinobu Mita
While accessing a unusual usb storage (ums-alauda, ums-cypress, ...), the module reference count is not incremented. Because these drivers allocate scsi hosts with usb_stor_host_template defined in usb-storage module. So these drivers always can be unloaded. This fixes it by preparing scsi host template which is initialized at module_init() for each ums-* driver. In order to minimize the difference in ums-* drivers, introduce module_usb_stor_driver() helper macro which is same as module_usb_driver() except that it also initializes scsi host template.
