usb: setup authorized_default attributes using usb_bus_notify

2019-08-08T14:07:34Z

Currently, the authorized_default and interface_authorized_default attributes for HCD are set up after the uevent has been sent to userland. This creates a race condition where userland may fail to access this file when processing the event. Move the appending of these attributes earlier relying on the usb_bus_notify dispatcher.

USB: USB 3.2 Add sysfs entries for a usb device rx_lanes and tx_lanes

2018-04-22T14:19:26Z

Add rx_lanes and tx_lanes lane count sysfs entries for a usb device struct usb_devuce rx_lanes and tx_lanes variables. Shows number of lanes used by the usb device Data rate of a device is the lane speed * lane count, for example USB 3.2 Gen 2x2 device uses 10Gbps signaling per lane, and has dual-lane support 10Gbps * 2 = 20Gbps Signed-off-by: Mathias Nyman Signed-off-by: Greg Kroah-Hartman

Merge tag 'usb-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

2017-11-14T05:14:07Z

Pull USB/PHY updates from Greg KH: "Here is the big set of USB and PHY driver updates for 4.15-rc1. There is the usual amount of gadget and xhci driver updates, along with phy and chipidea enhancements. There's also a lot of SPDX tags and license boilerplate cleanups as well, which provide some churn in the diffstat. Other major thing is the typec code that moved out of staging and into the "real" part of the drivers/usb/ tree, which was nice to see happen. All of these have been in linux-next with no reported issues for a while" * tag 'usb-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (263 commits) usb: gadget: f_fs: Fix use-after-free in ffs_free_inst USB: usbfs: compute urb->actual_length for isochronous usb: core: message: remember to reset 'ret' to 0 when necessary USB: typec: Remove remaining redundant license text USB: typec: add SPDX identifiers to some files USB: renesas_usbhs: rcar?.h: add SPDX tags USB: chipidea: ci_hdrc_tegra.c: add SPDX line USB: host: xhci-debugfs: add SPDX lines USB: add SPDX identifiers to all remaining Makefiles usb: host: isp1362-hcd: remove a couple of redundant assignments USB: adutux: remove redundant variable minor usb: core: add a new usb_get_ptm_status() helper usb: core: add a 'type' parameter to usb_get_status() usb: core: introduce a new usb_get_std_status() helper usb: core: rename usb_get_status() 'type' argument to 'recip' usb: core: add Status Type definitions USB: gadget: Remove redundant license text USB: gadget: function: Remove redundant license text USB: gadget: udc: Remove redundant license text USB: gadget: legacy: Remove redundant license text ...

USB: core: move existing SPDX tags to top of the file

2017-11-03T09:12:26Z

To match the rest of the kernel, the SPDX tags for the drivers/usb/core/ files are moved to the first line of the file. This makes it more obvious the tag is present as well as making it match the other 12k files in the tree with this location. It also uses // to match the "expected style" as well.

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()

2017-10-25T09:01:08Z

Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland Signed-off-by: Paul E.

USB: core: add missing license information to some files

2016-10-29T16:51:56Z

Some of the USB core files were missing explicit license information. As all files in the kernel tree are implicitly licensed under the GPLv2-only, be explicit in case someone get confused looking at individual files by using the SPDX nomenclature. Signed-off-by: Greg Kroah-Hartman
