2024-04-13USB: core: Fix deadlock in usb_deauthorize_interface()Alan Stern1-3/+13
commit 80ba43e9f799cbdd83842fc27db667289b3150f5 upstream. Among the attribute file callback routines in drivers/usb/core/sysfs.c, the interface_authorized_store() function is the only one which acquires a device lock on an ancestor device: It calls usb_deauthorize_interface(), which locks the interface's parent USB device. The will lead to deadlock if another process already owns that lock and tries to remove the interface, whether through a configuration change or because the device has been disconnected. As part of the removal procedure, device_del() waits for all ongoing sysfs attribute callbacks to complete. But usb_deauthorize_interface() can't complete until the device lock has been released, and the lock won't be released until the removal has finished. The mechanism provided by sysfs to prevent this kind of deadlock is to use the sysfs_break_active_protection() function, which tells sysfs not to wait for the attribute callback.

commit 69c63350e573367f9c8594162288cffa8a26d0d1 upstream. Unused USB ports may have bogus location data in ACPI PLD tables. This causes port peering failures as these unused USB2 and USB3 ports location may match. Due to these failures the driver prints a "usb: port power management may be unreliable" warning, and unnecessarily blocks port power off during runtime suspend. This was debugged on a couple DELL systems where the unused ports all returned zeroes in their location data. Similar bugreports exist for other systems. Don't try to peer or match ports that have connect type set to USB_PORT_NOT_USED.

2024-04-13usb: gadget: ncm: Fix handling of zero block length packetsKrishna Kurapati1-1/+1
commit f90ce1e04cbcc76639d6cba0fdbd820cd80b3c70 upstream. While connecting to a Linux host with CDC_NCM_NTB_DEF_SIZE_TX set to 65536, it has been observed that we receive short packets, which come at interval of 5-10 seconds sometimes and have block length zero but still contain 1-2 valid datagrams present. According to the NCM spec: "If wBlockLength = 0x0000, the block is terminated by a short packet. In this case, the USB transfer must still be shorter than dwNtbInMaxSize or dwNtbOutMaxSize. If exactly dwNtbInMaxSize or dwNtbOutMaxSize bytes are sent, and the size is a multiple of wMaxPacketSize for the given pipe, then no ZLP shall be sent. wBlockLength= 0x0000 must be used with extreme care, because of the possibility that the host and device may get out of sync, and because of test issues. wBlockLength = 0x0000 allows the sender to reduce latency by starting to send a very large NTB, and then shortening it when the sender discovers that there’s not sufficient data to justify sending a large NTB" However, there is a potential issue with the current implementation, as it checks for the occurrence of multiple NTBs in a single giveback by verifying if the leftover bytes to be processed is zero or not. If the block length reads zero, we would process the same NTB infintely because the leftover bytes is never zero and it leads to a crash. Fix this by bailing out if block length reads zero.

2024-04-13USB: usb-storage: Prevent divide-by-0 error in isd200_ata_commandAlan Stern1-5/+18
commit 014bcf41d946b36a8f0b8e9b5d9529efbb822f49 upstream. The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer. Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error).

2024-04-13usb: gadget: tegra-xudc: Fix USB3 PHY retrieval logicWayne Chang1-14/+25
[ Upstream commit 84fa943d93c31ee978355e6c6c69592dae3c9f59 ] This commit resolves an issue in the tegra-xudc USB gadget driver that incorrectly fetched USB3 PHY instances. The problem stemmed from the assumption of a one-to-one correspondence between USB2 and USB3 PHY names and their association with physical USB ports in the device tree. Previously, the driver associated USB3 PHY names directly with the USB3 instance number, leading to mismatches when mapping the physical USB ports. For instance, if using USB3-1 PHY, the driver expect the corresponding PHY name as 'usb3-1'. However, the physical USB ports in the device tree were designated as USB2-0 and USB3-0 as we only have one device controller, causing a misalignment. This commit rectifies the issue by adjusting the PHY naming logic. Now, the driver correctly correlates the USB2 and USB3 PHY instances, allowing the USB2-0 and USB3-1 PHYs to form a physical USB port pair while accurately reflecting their configuration in the device tree by naming them USB2-0 and USB3-0, respectively. The change ensures that the PHY and PHY names align appropriately, resolving the mismatch between physical USB ports and their associated names in the device tree.

2024-03-15xhci: handle isoc Babble and Buffer Overrun events properlyMichal Pecio1-1/+5
[ Upstream commit 7c4650ded49e5b88929ecbbb631efb8b0838e811 ] xHCI 4.9 explicitly forbids assuming that the xHC has released its ownership of a multi-TRB TD when it reports an error on one of the early TRBs. Yet the driver makes such assumption and releases the TD, allowing the remaining TRBs to be freed or overwritten by new TDs. The xHC should also report completion of the final TRB due to its IOC flag being set by us, regardless of prior errors. This event cannot be recognized if the TD has already been freed earlier, resulting in "Transfer event TRB DMA ptr not part of current TD" error message. Fix this by reusing the logic for processing isoc Transaction Errors. This also handles hosts which fail to report the final completion. Fix transfer length reporting on Babble errors. They may be caused by device malfunction, no guarantee that the buffer has been filled.

2024-03-15xhci: process isoc TD properly when there was a transaction error mid TD.Mathias Nyman2-14/+61
[ Upstream commit 5372c65e1311a16351ef03dd096ff576e6477674 ] The last TRB of a isoc TD might not trigger an event if there was an error event for a TRB mid TD. This is seen on a NEC Corporation uPD720200 USB 3.0 Host After an error mid a multi-TRB TD the xHC should according to xhci 4.9.1 generate events for passed TRBs with IOC flag set if it proceeds to the next TD. This event is either a copy of the original error, or a "success" transfer event. If that event is missing then the driver and xHC host get out of sync as the driver is still expecting a transfer event for that first TD, while xHC host is already sending events for the next TD in the list. This leads to "Transfer event TRB DMA ptr not part of current TD" messages. As a solution we tag the isoc TDs that get error events mid TD. If an event doesn't match the first TD, then check if the tag is set, and event points to the next TD. In that case give back the fist TD and process the next TD normally Make sure TD status and transferred length stay valid in both cases with and without final TD completion event.

2024-03-15xhci: remove extra loop in interrupt contextMathias Nyman2-7/+16
[ Upstream commit 55f6153d8cc8eff0852d108f80087fdf41dc2169 ] When finishing a TD we walk the endpoint dequeue trb pointer until it matches the last TRB of the TD. TDs can contain over 100 TRBs, meaning we call a function 100 times, do a few comparisons and increase a couple values for each of these calls, all in interrupt context. This can all be avoided by adding a pointer to the last TRB segment, and a number of TRBs in the TD. So instead of walking through each TRB just set the new dequeue segment, pointer, and number of free TRBs directly. Getting rid of the while loop also reduces the risk of getting stuck in a infinite loop in the interrupt handler. Loop relied on valid matching dequeue and last_trb values to break.

2024-03-01usb: gadget: ncm: Avoid dropping datagrams of properly parsed NTBsKrishna Kurapati1-1/+9
commit 76c51146820c5dac629f21deafab0a7039bc3ccd upstream. It is observed sometimes when tethering is used over NCM with Windows 11 as host, at some instances, the gadget_giveback has one byte appended at the end of a proper NTB. When the NTB is parsed, unwrap call looks for any leftover bytes in SKB provided by u_ether and if there are any pending bytes, it treats them as a separate NTB and parses it. But in case the second NTB (as per unwrap call) is faulty/corrupt, all the datagrams that were parsed properly in the first NTB and saved in rx_list are dropped. Adding a few custom traces showed the following: [002] d..1 7828.532866: dwc3_gadget_giveback: ep1out: req 000000003868811a length 1025/16384 zsI ==> 0 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb toprocess: 1025 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb seq: 0xce67 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x400 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb ndp_len: 0x10 [002] d..1 7828.532869: ncm_unwrap_ntb: K: Parsed NTB with 1 frames In this case, the giveback is of 1025 bytes and block length is 1024. The rest 1 byte (which is 0x00) won't be parsed resulting in drop of all datagrams in rx_list. Same is case with packets of size 2048: [002] d..1 7828.557948: dwc3_gadget_giveback: ep1out: req 0000000011dfd96e length 2049/16384 zsI ==> 0 [002] d..1 7828.557949: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.557950: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x800 Lecroy shows one byte coming in extra confirming that the byte is coming in from PC: Transfer 2959 - Bytes Transferred(1025) Timestamp((18.524 843 590) - Transaction 8391 - Data(1025 bytes) Timestamp(18.524 843 590) --- Packet 4063861 Data(1024 bytes) Duration(2.117us) Idle(14.700ns) Timestamp(18.524 843 590) --- Packet 4063863 Data(1 byte) Duration(66.160ns) Time(282.000ns) Timestamp(18.524 845 722) According to Windows driver, no ZLP is needed if wBlockLength is non-zero, because the non-zero wBlockLength has already told the function side the size of transfer to be expected. However, there are in-market NCM devices that rely on ZLP as long as the wBlockLength is multiple of wMaxPacketSize. To deal with such devices, it pads an extra 0 at end so the transfer is no longer multiple of wMaxPacketSize.

According to the spec this feature may be used based only the following three conditions: 6.5.3 a_alt_hnp_support Setting this feature indicates to the B-device that it is connected to an A-device port that is not capable of HNP, but that the A-device does have an alternate port that is capable of HNP. The A-device is required to set this feature under the following conditions: • the A-device has multiple receptacles • the A-device port that connects to the B-device does not support HNP • the A-device has another port that does support HNP A check for the third and first condition is missing.

commit 2840143e393a4ddc1caab4372969ea337371168c upstream. In case of a spurious or otherwise delayed notification it is possible that CCI still reports the previous completion. The UCSI spec is aware of this and provides two completion bits in CCI, one for normal commands and one for acks. As acks and commands alternate the notification handler can determine if the completion bit is from the current command. The initial UCSI code correctly handled this but the distinction between the two completion bits was lost with the introduction of the new API. To fix this revive the ACK_PENDING bit for ucsi_acpi and only complete commands if the completion bit matches.
