2019-08-22libpayload: usbmsc: Factor out usb_msc_force_init() functionJulius Werner
We're planning to have a use case with a custom USB device that implements the USB mass storage protocol on its bulk endpoints, but does not have the normal MSC class/protocol interface descriptors and does not support class-specific control requests (Get Max LUN and Bulk-Only Reset). We'd like to identify/enumerate the device via usb_generic_create() in our payload but then reuse all the normal MSC driver code. In order to make that possible, this patch factors a new usb_msc_force_init() function out of usb_msc_init() which will initialize an MSC device without checking its descriptors. It also adds some "quirks" flags that allow devices registered this way to customize behavior of the MSC stack.

2019-08-22libpayload: usbmsc: Skip zero-length packets at end of dataJulius Werner
Some broken USB mass storage devices send another zero-length packet at the end of the data part of a transfer if the amount of data was evenly divisible by the packet size (which is pretty much always the case for block reads). This packet will get interpreted as the CSW and screw up the MSC state machine. This patch works around this issue by retrying the CSW transfer when it was received as exactly 0 bytes. This is the same mitigation the Linux kernel uses and harmless for correctly behaving devices. Also tighten validation of the CSW a little, making sure we verify the length before we read any fields and checking the signature in addition to the tag.

2014-12-30libpayload: usbmsc: Implement limited LUN supportJulius Werner
I always thought the support for multiple logical SCSI units in the USB mass storage class was a dead feature. Turns out that it's actually used by SD card readers that provide multiple slots (e.g. one regular sized and one micro-SD). Implementing perfect support for that would require a major redesign of the whole MSC stack, since the one device -> one disk assumption is deeply embedded in our data structures. Instead, this patch implements a poor man's LUN support that will just cycle through all available LUNs (in multiple calls to usb_msc_poll()) until it finds a connected device. This should be reasonable enough to allow these card readers to be usable while only requiring superficial changes. Also removes the unused 'protocol' attribute of usb_msc_inst_t.

2014-12-30libpayload: usbmsc: Set correct allocation length for REQUEST SENSEJulius Werner
So I was debugging this faulty USB SD card reader that would just fail it's REQUEST SENSE response for some reason (sending the CSW immediately without the data), cursing those damn device vendors for building non-compliant crap like I always do... when I noticed that we do not actually set the Allocation Length field in our REQUEST SENSE command block at all! We set a length in the CBW, but the SCSI command still has its own length field and the SCSI spec specifically says that the device has to return the exact amount of bytes listed there (even if it's 0). I don't know what's more suprising: that we had such a blatant bug in this stack for so long, or that this card reader is really the first device to actually be spec compliant in that regard. This patch fixes the bug and changes the command block structures to be a little easier to read (why that field was called 'lun' before is beyond me... LUN is a transport level thing and should never appear in the command block at all, for any command). It also fixes a memcpy() in wrap_cbw() to avoid a read buffer overflow that might expose stack frame data to the device.

2014-08-18libpayload: usbmsc: Remove DETACHED state from MSC device structureJulius Werner
The USB MSC device structure contains a "ready" state that can be either "ready", "not ready" or "detached". The last one can only be assigned when the device is completely unresponsive and gets forcefully logically detached via usb_detach_device(). This call (at least in the current version) also calls all destructors and frees the complete usbdev_t structure (including the MSC specific part), which unfortunately makes storing the "detached" state in that very structure a little pointless. This patch reduces the "ready" value to a simple boolean and makes sure that all detachment cases immediately return from the MSC driver, carefully avoiding any use-after-free opportunities.

2014-08-12libpayload: Make USB transfer functions return amount of bytesJulius Werner
The USB bulk and control transfer functions in libpayload currently always return 0 for success and 1 for all errors. This is sufficient for current use cases (essentially just mass storage), but other classes (like certain Ethernet adapters) need to be able to tell if a transfer reached the intended amount of bytes, or if it fell short. This patch slightly changes that USB API to return -1 on errors, and the amount of transferred bytes on successes. All drivers in the current libpayload mainline are modified to conform to the new error detection model. Any third party users of this API will need to adapt their if (...<controller>->bulk/control(...)) checks to if (...<controller>->bulk/control(...) < 0) as well. The host controller drivers for OHCI and EHCI correctly implement the new behavior. UHCI and the XHCI stub just comply with the new API by returning 0 or -1, but do not actually count the returned bytes.

This is inappropriate because it forms a 1:1 mapping of USB device to disk leading to the inability to remove the disk and/or handle "hot plug" card insertion and removals. To alleviate this issue introduce the notion of ready to the usbmsc structure. It tracks detached, not ready, and ready states. The polling routine is then used to track not ready to ready transitions thereby creating and removing disks appropriately. This handles the case of inserting and removing a card that shows up as a new disk. Booted recovery mode. Able to observe inerstion and removal of sdcard.

2013-11-25libpayload: usb mass storage detect empty mediaAaron Durbin
There is currently a hard-coded 30 sec delay in the mass storage driver while waiting for each device to become ready. However, mass storage card readers that are empty return an error code on the TEST UNIT READY command. A REQUEST SENSE command then needs to be issued and interrogate the data to determine if no media is present. If no media determination is found to be true the USB device is no longer considered a candidate to be a disk. This code does lead to the fact that the media card reader needs to be populated at enumeration time. I suspect this is not an issue as it appears the storage stack in libpayload can't handle removable media coming online later. Booted recovery and dev modes. Noted that removable mass storage devices with no media were ignored without any boot delay.

2012-06-22libpayload: Shutdown reasonably if we can't init usb msc deviceNico Huber
This lets the init of usb mass storage return if the device configuration is unusable. Also add some checks for proper shutdown so we don't free/remove an uninitialized device.

2012-06-21libpayload: Detach unresponsive usb mass storage devicesNico Huber
This enables logical detachment of unresponsive usb devices (i.e. devices not responding to control transfers) in the usb mass storage driver. Without the detection of unresponsive devices we wait way too long for the device to become ready.

2008-09-02This patch adds USB capabilities to libpayload. It requires somePatrick Georgi
memalign implementation (eg. the one I sent yesterday). Features: - UHCI controller driver - UHCI root hub driver - USB MSC (Mass Storage Class) driver - skeleton of a USB HID driver (requires better interrupt transfer handling, which is TODO) - skeleton of a USB hub driver (needs several blank spots filled in, eg. power management. Again: TODO) OHCI and EHCI are not supported, though OHCI support should be rather easy as the stack provides reasonable abstractions (or so I hope). EHCI will probably be more complicated. Isochronous transfers (eg. webcams, audio stuff, ...) are not supported. They can be, but I doubt we'll have a reason for that in the boot environment. The MSC driver was tested against a couple of USB flash drives, and should be reasonably tolerant by now. But I probably underestimate the amount of bugs present in USB flash drives, so feedback is welcome.
