2018-12-06xhci: Prevent U1/U2 link pm states if exit latency is too longMathias Nyman1-0/+16
Don't allow USB3 U1 or U2 if the latency to wake up from the U-state reaches the service interval for a periodic endpoint. This is according to xhci 1.1 specification section 4.23.5.2 extra note: "Software shall ensure that a device is prevented from entering a U-state where its worst case exit latency approaches the ESIT." Allowing too long exit latencies for periodic endpoint confuses xHC internal scheduling, and new devices may fail to enumerate with a "Not enough bandwidth for new device state" error from the host.

2018-12-06xhci: workaround CSS timeout on AMD SNPS 3.0 xHCSandeep Singh3-4/+29
Occasionally AMD SNPS 3.0 xHC does not respond to CSS when set, also it does not flag anything on SRE and HCE to point the internal xHC errors on USBSTS register. This stalls the entire system wide suspend and there is no point in stalling just because of xHC CSS is not responding. To work around this problem, if the xHC does not flag anything on SRE and HCE, we can skip the CSS timeout and allow the system to continue the suspend. Once the system resume happens we can internally reset the controller using XHCI_RESET_ON_RESUME quirk Signed-off-by: Shyam Sundar S K <Shyam-sundar.S-k@amd.com> Signed-off-by: Sandeep Singh <Sandeep.Singh@amd.com> cc: Nehal Shah <Nehal-bakulchandra.Shah@amd.com> Cc: <stable@vger.kernel.org> Tested-by: Kai-Heng Feng <kai.heng.feng@canonical.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2018-12-05USB: serial: console: fix reported terminal settingsJohan Hovold1-1/+1
The USB-serial console implementation has never reported the actual terminal settings used. Despite storing the corresponding cflags in its struct console, these were never honoured on later tty open() where the tty termios would be left initialised to the driver defaults. Unlike the serial console implementation, the USB-serial code calls subdriver open() already at console setup. While calling set_termios() and write() before open() looks like it could work for some USB-serial drivers, others definitely do not expect this, so modelling this after serial core is going to be intrusive, if at all possible. Instead, use a (renamed) tty helper to save the termios data used at console setup so that the tty termios reflects the actual terminal settings after a subsequent tty open(). Note that the calls to tty_init_termios() (tty_driver_install()) and tty_save_termios() are serialised using the disconnect mutex. This specifically fixes a regression that was triggered by a recent change adding software flow control to the pl2303 driver: a getty trying to disable flow control while leaving the baud rate unchanged would now also set the baud rate to the driver default (prior to the flow-control change this had been a noop).

2018-12-05usb: quirk: add no-LPM quirk on SanDisk Ultra Flair deviceHarry Pan1-0/+4
Some lower volume SanDisk Ultra Flair in 16GB, which the VID:PID is in 0781:5591, will aggressively request LPM of U1/U2 during runtime, when using this thumb drive as the OS installation key we found the device will generate failure during U1 exit path making it dropped from the USB bus, this causes a corrupted installation in system at the end. i.e., [ 166.918296] hub 2-0:1.0: state 7 ports 7 chg 0000 evt 0004 [ 166.918327] usb usb2-port2: link state change [ 166.918337] usb usb2-port2: do warm reset [ 166.970039] usb usb2-port2: not warm reset yet, waiting 50ms [ 167.022040] usb usb2-port2: not warm reset yet, waiting 200ms [ 167.276043] usb usb2-port2: status 02c0, change 0041, 5.0 Gb/s [ 167.276050] usb 2-2: USB disconnect, device number 2 [ 167.276058] usb 2-2: unregistering device [ 167.276060] usb 2-2: unregistering interface 2-2:1.0 [ 167.276170] xhci_hcd 0000:00:15.0: shutdown urb ffffa3c7cc695cc0 ep1in-bulk [ 167.284055] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [ 167.284064] sd 0:0:0:0: [sda] tag#0 CDB: Read(10) 28 00 00 33 04 90 00 01 00 00 ... Analyzed the USB trace in the link layer we realized it is because of the 6-ms timer of tRecoveryConfigurationTimeout which documented on the USB 3.2 Revision 1.0, the section 7.5.10.4.2 of "Exit from Recovery.Configuration"; device initiates U1 exit -> Recovery.Active -> Recovery.Configuration, then the host timer timeout makes the link transits to eSS.Inactive -> Rx.Detect follows by a Warm Reset. Interestingly, the other higher volume of SanDisk Ultra Flair sharing the same VID:PID, such as 64GB, would not request LPM during runtime, it sticks at U0 always, thus disabling LPM does not affect those thumb drives at all. The same odd occures in SanDisk Ultra Fit 16GB, VID:PID in 0781:5583.

list_for_each_entry_safe() is not safe for deleting entries from the list if the spin lock, which protects it, is released and reacquired during the list iteration.

2018-11-26USB: omap_udc: fix crashes on probe error and module removalAaro Koskinen1-31/+19
We currently crash if usb_add_gadget_udc_release() fails, since the udc->done is not initialized until in the remove function. Furthermore, on module removal the udc data is accessed although the release function is already triggered by usb_del_gadget_udc() early in the function. Fix by rewriting the release and remove functions, basically moving all the cleanup into the release function, and doing the completion only in the module removal case. The patch fixes omap_udc module probe with a failing gadged, and also allows the removal of omap_udc. Tested by running "modprobe omap_udc; modprobe -r omap_udc" in a loop.

USB3 devices don't show up as connected and enabled until USB3 link trainig completes. On a fast booting platform with a slow USB3 link training the link might reach the connected enabled state just as the bus is suspending. If this device is discovered first time by the xhci_bus_suspend() routine it will be put to U3 suspended state like the other ports which failed to suspend earlier. The hub thread will notice the connect change and resume the bus, moving the port back to U0 This U0 -> U3 -> U0 transition right after being connected seems to be too much for some devices, causing them to first go to SS.Inactive state, and finally end up stuck in a polling state with reset asserted Fix this by failing the bus suspend if a port has a connect change or is in a polling state in xhci_bus_suspend().

This will clear the USB_PORT_FEAT_C_CONNECTION bit in case of a hub port reset only if a device is was attached to the hub port before resetting the hub port. Using a Lenovo T480s attached to the ultra dock it was not possible to detect some usb-c devices at the dock usb-c ports because the hub_port_reset code will clear the USB_PORT_FEAT_C_CONNECTION bit after the actual hub port reset. Using this device combo the USB_PORT_FEAT_C_CONNECTION bit was set between the actual hub port reset and the clear of the USB_PORT_FEAT_C_CONNECTION bit. This ends up with clearing the USB_PORT_FEAT_C_CONNECTION bit after the new device was attached such that it was not detected. This patch will not clear the USB_PORT_FEAT_C_CONNECTION bit if there is currently no device attached to the port before the hub port reset. This will avoid clearing the connection bit for new attached devices.

2018-11-09xhci: Add quirk to workaround the errata seen on Cavium Thunder-X2 SocCherian, George3-1/+40
Implement workaround for ThunderX2 Errata-129 (documented in CN99XX Known Issues" available at Cavium support site). As per ThunderX2errata-129, USB 2 device may come up as USB 1 if a connection to a USB 1 device is followed by another connection to a USB 2 device, the link will come up as USB 1 for the USB 2 device. Resolution: Reset the PHY after the USB 1 device is disconnected. The PHY reset sequence is done using private registers in XHCI register space. After the PHY is reset we check for the PLL lock status and retry the operation if it fails. From our tests, retrying 4 times is sufficient. Add a new quirk flag XHCI_RESET_PLL_ON_DISCONNECT to invoke the workaround in handle_xhci_port_status().

Realtek USB3.0 Card Reader [0bda:0328] reports wrong port status on Cannon lake PCH USB3.1 xHCI [8086:a36d] after resume from S3, after clear port reset it works fine. Since this device is registered on USB3 roothub at boot, when port status reports not superspeed, xhci_get_port_status will call an uninitialized completion in bus_state[0].

2018-11-09xhci: Fix leaking USB3 shared_hcd at xhci removalMathias Nyman6-8/+14
Ensure that the shared_hcd pointer is valid when calling usb_put_hcd() The shared_hcd is removed and freed in xhci by first calling usb_remove_hcd(xhci->shared_hcd), and later usb_put_hcd(xhci->shared_hcd) Afer commit fe190ed0d602 ("xhci: Do not halt the host until both HCD have disconnected their devices.") the shared_hcd was never properly put as xhci->shared_hcd was set to NULL before usb_put_hcd(xhci->shared_hcd) was called. shared_hcd (USB3) is removed before primary hcd (USB2). While removing the primary hcd we might need to handle xhci interrupts to cleanly remove last USB2 devices, therefore we need to set xhci->shared_hcd to NULL before removing the primary hcd to let xhci interrupt handler know shared_hcd is no longer available. xhci-plat.c, xhci-histb.c and xhci-mtk first create both their hcd's before adding them. so to keep the correct reverse removal order use a temporary shared_hcd variable for them. For more details see commit 4ac53087d6d4 ("usb: xhci: plat: Create both HCDs before adding them") Fixes: fe190ed0d602 ("xhci: Do not halt the host until both HCD have disconnected their devices.")

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull siginfo updates from Eric Biederman: "I have been slowly sorting out siginfo and this is the culmination of that work. The primary result is in several ways the signal infrastructure has been made less error prone. The code has been updated so that manually specifying SEND_SIG_FORCED is never necessary. The conversion to the new siginfo sending functions is now complete, which makes it difficult to send a signal without filling in the proper siginfo fields. At the tail end of the patchset comes the optimization of decreasing the size of struct siginfo in the kernel from 128 bytes to about 48 bytes on 64bit. The fundamental observation that enables this is by definition none of the known ways to use struct siginfo uses the extra bytes. This comes at the cost of a small user space observable difference. For the rare case of siginfo being injected into the kernel only what can be copied into kernel_siginfo is delivered to the destination, the rest of the bytes are set to 0. For cases where the signal and the si_code are known this is safe, because we know those bytes are not used. For cases where the signal and si_code combination is unknown the bits that won't fit into struct kernel_siginfo are tested to verify they are zero, and the send fails if they are not. I made an extensive search through userspace code and I could not find anything that would break because of the above change. If it turns out I did break something it will take just the revert of a single change to restore kernel_siginfo to the same size as userspace siginfo. Testing did reveal dependencies on preferring the signo passed to sigqueueinfo over si->signo, so bit the bullet and added the complexity necessary to handle that case. Testing also revealed bad things can happen if a negative signal number is passed into the system calls. Something no sane application will do but something a malicious program or a fuzzer might do. So I have fixed the code that performs the bounds checks to ensure negative signal numbers are handled" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (80 commits) signal: Guard against negative signal numbers in copy_siginfo_from_user32 signal: Guard against negative signal numbers in copy_siginfo_from_user signal: In sigqueueinfo prefer sig not si_signo signal: Use a smaller struct siginfo in the kernel signal: Distinguish between kernel_siginfo and siginfo signal: Introduce copy_siginfo_from_user and use it's return value signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE signal: Fail sigqueueinfo if si_signo != sig signal/sparc: Move EMT_TAGOVF into the generic siginfo.h signal/unicore32: Use force_sig_fault where appropriate signal/unicore32: Generate siginfo in ucs32_notify_die signal/unicore32: Use send_sig_fault where appropriate signal/arc: Use force_sig_fault where appropriate signal/arc: Push siginfo generation into unhandled_exception signal/ia64: Use force_sig_fault where appropriate signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn signal/ia64: Use the generic force_sigsegv in setup_frame signal/arm/kvm: Use send_sig_mceerr signal/arm: Use send_sig_fault where appropriate signal/arm: Use force_sig_fault where appropriate ...
2018-10-24iov_iter: Separate type from direction and use accessor functionsDavid Howells1-1/+1
In the iov_iter struct, separate the iterator type from the iterator direction and use accessor functions to access them in most places. Convert a bunch of places to use switch-statements to access them rather then chains of bitwise-AND statements. This makes it easier to add further iterator types. Also, this can be more efficient as to implement a switch of small contiguous integers, the compiler can use ~50% fewer compare instructions than it has to use bitwise-and instructions. Further, cease passing the iterator type into the iterator setup function. The iterator function can set that itself. Only the direction is required. Signed-off-by: David Howells <dhowells@redhat.com>
