2024-01-05usb: fotg210-hcd: delete an incorrect bounds testDan Carpenter
[ Upstream commit 7fbcd195e2b8cc952e4aeaeb50867b798040314c ] Here "temp" is the number of characters that we have written and "size" is the size of the buffer. The intent was clearly to say that if we have written to the end of the buffer then stop. However, for that to work the comparison should have been done on the original "size" value instead of the "size -= temp" value. Not only will that not trigger when we want to, but there is a small chance that it will trigger incorrectly before we want it to and we break from the loop slightly earlier than intended. This code was recently changed from using snprintf() to scnprintf(). With snprintf() we likely would have continued looping and passed a negative size parameter to snprintf(). This would have triggered an annoying WARN(). Now that we have converted to scnprintf() "size" will never drop below 1 and there is no real need for this test. We could change the condition to "if (temp <= 1) goto done;" but just deleting the test is cleanest.

2024-01-01usb-storage: Add quirk for incorrect WP on Kingston DT Ultimate 3.0 G3Tasos Sahanidis
commit 772685c14743ad565bb271041ad3c262298cd6fc upstream. This flash drive reports write protect during the first mode sense. In the past this was not an issue as the kernel called revalidate twice, thus asking the device for its write protect status twice, with write protect being disabled in the second mode sense. However, since commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twice") that is no longer the case, thus the device shows up read only. [490891.289495] sd 12:0:0:0: [sdl] Write Protect is on [490891.289497] sd 12:0:0:0: [sdl] Mode Sense: 2b 00 80 08 This does not appear to be a timing issue, as enabling the usbcore quirk USB_QUIRK_DELAY_INIT has no effect on write protect.

commit b17b7fe6dd5c6ff74b38b0758ca799cdbb79e26e upstream. When typec_altmode_put_partner is called by a plug altmode upon release, the port altmode the plug belongs to will not remove its reference to the plug.

2023-12-08usb: config: fix iteration issue in 'usb_get_bos_descriptor()'Niklas Neronin
[ Upstream commit 974bba5c118f4c2baf00de0356e3e4f7928b4cbc ] The BOS descriptor defines a root descriptor and is the base descriptor for accessing a family of related descriptors. Function 'usb_get_bos_descriptor()' encounters an iteration issue when skipping the 'USB_DT_DEVICE_CAPABILITY' descriptor type. This results in the same descriptor being read repeatedly. To address this issue, a 'goto' statement is introduced to ensure that the pointer and the amount read is updated correctly. This ensures that the function iterates to the next descriptor instead of reading the same descriptor repeatedly.

[ Upstream commit 7a09c1269702db8eccb6f718da2b00173e1e0034 ] It has been pointed out that the kernel log messages warning about problems in USB configuration and related descriptors are vexing for users. The warning log level has a fairly high priority, but the user can do nothing to fix the underlying errors in the device's firmware. To reduce the amount of useless information produced by tools that filter high-priority log messages, we can change these warnings to notices, i.e., change dev_warn() to dev_notice(). The same holds for a few messages that currently use dev_err(): Unless they indicate a failure that might make a device unusable (such as inability to transfer a config descriptor), change them to dev_notice() also.

[ Upstream commit 16b7e0cccb243033de4406ffb4d892365041a1e7 ] Commits 7b8ef22ea547 ("usb: xhci: plat: Add USB phy support") and 9134c1fd0503 ("usb: xhci: plat: Add USB 3.0 phy support") added support for looking up legacy PHYs from the sysdev devicetree node and initialising them. This broke drivers such as dwc3 which manages PHYs themself as the PHYs would now be initialised twice, something which specifically can lead to resources being left enabled during suspend (e.g. with the usb_phy_generic PHY driver). As the dwc3 driver uses driver-name matching for the xhci platform device, fix this by only looking up and initialising PHYs for devices that have been matched using OF. Note that checking that the platform device has a devicetree node would currently be sufficient, but that could lead to subtle breakages in case anyone ever tries to reuse an ancestor's node.

2023-12-03usb: cdnsp: Fix deadlock issue during using NCM gadgetPawel Laszczak
commit 58f2fcb3a845fcbbad2f3196bb37d744e0506250 upstream. The interrupt service routine registered for the gadget is a primary handler which mask the interrupt source and a threaded handler which handles the source of the interrupt. Since the threaded handler is voluntary threaded, the IRQ-core does not disable bottom halves before invoke the handler like it does for the forced-threaded handler. Due to changes in networking it became visible that a network gadget's completions handler may schedule a softirq which remains unprocessed. The gadget's completion handler is usually invoked either in hard-IRQ or soft-IRQ context. In this context it is enough to just raise the softirq because the softirq itself will be handled once that context is left. In the case of the voluntary threaded handler, there is nothing that will process pending softirqs. Which means it remain queued until another random interrupt (on this CPU) fires and handles it on its exit path or another thread locks and unlocks a lock with the bh suffix. Worst case is that the CPU goes idle and the NOHZ complains about unhandled softirqs. Disable bottom halves before acquiring the lock (and disabling interrupts) and enable them after dropping the lock. This ensures that any pending softirqs will handled right away. cc: stable@vger.kernel.org Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver") Signed-off-by: Pawel Laszczak <pawell@cadence.com> Acked-by: Peter Chen <peter.chen@kernel.org> Link: https://lore.kernel.org/r/20231108093125.224963-1-pawell@cadence.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2023-11-28usb: gadget: f_ncm: Always set current gadget in ncm_bind()Hardik Gajjar
[ Upstream commit a04224da1f3424b2c607b12a3bd1f0e302fb8231 ] Previously, gadget assignment to the net device occurred exclusively during the initial binding attempt. Nevertheless, the gadget pointer could change during bind/unbind cycles due to various conditions, including the unloading/loading of the UDC device driver or the detachment/reconnection of an OTG-capable USB hub device. This patch relocates the gether_set_gadget() function out from ncm_opts->bound condition check, ensuring that the correct gadget is assigned during each bind request. The provided logs demonstrate the consistency of ncm_opts throughout the power cycle, while the gadget may change. * OTG hub connected during boot up and assignment of gadget and ncm_opts pointer [ 2.366301] usb 2-1.5: New USB device found, idVendor=2996, idProduct=0105 [ 2.366304] usb 2-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 2.366306] usb 2-1.5: Product: H2H Bridge [ 2.366308] usb 2-1.5: Manufacturer: Aptiv [ 2.366309] usb 2-1.5: SerialNumber: 13FEB2021 [ 2.427989] usb 2-1.5: New USB device found, VID=2996, PID=0105 [ 2.428959] dabridge 2-1.5:1.0: dabridge 2-4 total endpoints=5, 0000000093a8d681 [ 2.429710] dabridge 2-1.5:1.0: P(0105) D(22.06.22) F(17.3.16) H(1.1) high-speed [ 2.429714] dabridge 2-1.5:1.0: Hub 2-2 P(0151) V(06.87) [ 2.429956] dabridge 2-1.5:1.0: All downstream ports in host mode [ 2.430093] gadget 000000003c414d59 ------> gadget pointer * NCM opts and associated gadget pointer during First ncm_bind [ 34.763929] NCM opts 00000000aa304ac9 [ 34.763930] NCM gadget 000000003c414d59 * OTG capable hub disconnecte or assume driver unload.

2023-11-20usb: dwc2: fix possible NULL pointer dereference caused by driver concurrencyJia-Ju Bai
[ Upstream commit ef307bc6ef04e8c1ea843231db58e3afaafa9fa6 ] In _dwc2_hcd_urb_enqueue(), "urb->hcpriv = NULL" is executed without holding the lock "hsotg->lock". In _dwc2_hcd_urb_dequeue(): spin_lock_irqsave(&hsotg->lock, flags); ... if (!urb->hcpriv) { dev_dbg(hsotg->dev, "## urb->hcpriv is NULL ##\n"); goto out; } rc = dwc2_hcd_urb_dequeue(hsotg, urb->hcpriv); // Use urb->hcpriv ... out: spin_unlock_irqrestore(&hsotg->lock, flags); When _dwc2_hcd_urb_enqueue() and _dwc2_hcd_urb_dequeue() are concurrently executed, the NULL check of "urb->hcpriv" can be executed before "urb->hcpriv = NULL". After urb->hcpriv is NULL, it can be used in the function call to dwc2_hcd_urb_dequeue(), which can cause a NULL pointer dereference. This possible bug is found by an experimental static analysis tool developed by myself. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported, when my tool analyzes the source code of Linux 6.5. To fix this possible bug, "urb->hcpriv = NULL" should be executed with holding the lock "hsotg->lock". After using this patch, my tool never reports the possible bug, with the kernelconfiguration allyesconfig for x86_64. Because I have no associated hardware, I cannot test the patch in runtime testing, and just verify it according to the code logic.

2023-11-08usb: raw-gadget: properly handle interrupted requestsAndrey Konovalov
commit e8033bde451eddfb9b1bbd6e2d848c1b5c277222 upstream. Currently, if a USB request that was queued by Raw Gadget is interrupted (via a signal), wait_for_completion_interruptible returns -ERESTARTSYS. Raw Gadget then attempts to propagate this value to userspace as a return value from its ioctls. However, when -ERESTARTSYS is returned by a syscall handler, the kernel internally restarts the syscall. This doesn't allow userspace applications to interrupt requests queued by Raw Gadget (which is required when the emulated device is asked to switch altsettings). It also violates the implied interface of Raw Gadget that a single ioctl must only queue a single USB request. Instead, make Raw Gadget do what GadgetFS does: check whether the request was interrupted (dequeued with status == -ECONNRESET) and report -EINTR to userspace.

[ Upstream commit e59e38158c61162f2e8beb4620df21a1585117df ] The USB2412 is a 2-Port USB 2.0 hub controller that provides a reset pin and a single 3v3 powre source, which makes it suitable to be controlled by the onboard_hub driver. This hub has the same reset timings as USB2514/2517 and the same onboard hub specific-data can be reused for USB2412.

commit 427694cfaafa565a3db5c5ea71df6bc095dca92f upstream. When NCM is used with hosts like Windows PC, it is observed that there are multiple NTB's contained in one usb request giveback. Since the driver unwraps the obtained request data assuming only one NTB is present, we loose the subsequent NTB's present resulting in data loss. Fix this by checking the parsed block length with the obtained data length in usb request and continue parsing after the last byte of current NTB.

commit a00e197daec52bcd955e118f5f57d706da5bfe50 upstream. Currently if ucsi_send_command() fails, then we bail out without clearing EVENT_PENDING flag. So when the next connector change event comes, ucsi_connector_change() won't queue the con->work, because of which none of the new events will be processed. Fix this by clearing EVENT_PENDING flag if ucsi_send_command() fails.

commit 89434b069e460967624903b049e5cf5c9e6b99b9 upstream. Upon receiving an ACK for a sent EXIT_MODE message, the DisplayPort driver currently resets the status and configuration of the port partner. The hpd signal is not updated despite being part of the status, so the Display stack can still transmit video despite typec_altmode_exit placing the lanes in a Safe State. Set hpd to low when a sent EXIT_MODE message is ACK'ed.
