2022-03-26T20:08:25Z

Pull USB/Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt changes for 5.18-rc1. Nothing major in here, just lots of little improvements and cleanups and new device support. Highlights are: - list iterator fixups for when we walk past the end of the list (a common problem that was cut/pasted in almost all USB gadget drivers) - xen USB driver "hardening" for malicious hosts - xhci driver updates and fixes for more hardware types - xhci debug cable fixes to make it actually work again - usb gadget audio driver improvements - usb gadget storage fixes to work with OS-X - lots of other small usb gadget fixes and updates - USB DWC3 driver improvements for more hardware types - Lots of other small USB driver improvements - DTS updates for some USB platforms All of these have been in linux-next for a while with no reported issues" * tag 'usb-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (172 commits) usb: gadget: fsl_qe_udc: Add missing semicolon in qe_ep_dequeue() dt-bindings: usb: mtk-xhci: add compatible for mt8186 usb: dwc3: Issue core soft reset before enabling run/stop usb: gadget: Makefile: remove ccflags-y USB: usb-storage: Fix use of bitfields for hardware data in ene_ub6250.c usb: gadget: eliminate anonymous module_init & module_exit usb: usbip: eliminate anonymous module_init & module_exit xen/usb: harden xen_hcd against malicious backends usb: dwc3: gadget: Wait for ep0 xfers to complete during dequeue usb: dwc3: gadget: move cmd_endtransfer to extra function usb: dwc3: gadget: ep_queue simplify isoc start condition xen/usb: don't use arbitrary_virt_to_machine() usb: isp1760: remove redundant max_packet() macro usb: oxu210hp-hcd: remove redundant call to max_packet() macro usb: common: usb-conn-gpio: Make VBUS supply completely optional USB: storage: ums-realtek: fix error code in rts51x_read_mem() usb: early: xhci-dbc: Fix xdbc number parsing usb: early: xhci-dbc: Remove duplicate keep parsing x86/tsc: Be consistent about use_tsc_delay() usb: gadget: udc: s3c2410: remove usage of list iterator past the loop body ...

usb: gadget: f_mass_storage: Make CD-ROM emulation work with Mac OS-X

2022-01-26T13:05:35Z

Mac OS-X expects CD-ROM TOC in raw format (i.e. format:2). It also sends the READ_TOC CDB in old style SFF8020i format. i.e. 2 format bits are encoded in MSBs of CDB byte 9. This patch will enable CD-ROM emulation to work with Mac OS-X. Tested on Mac OS X v10.6.3.

exit: Rename complete_and_exit to kthread_complete_and_exit

2021-12-13T18:04:45Z

Update complete_and_exit to call kthread_exit instead of do_exit. Change the name to reflect this change in functionality. All of the users of complete_and_exit are causing the current kthread to exit so this change makes it clear what is happening. Move the implementation of kthread_complete_and_exit from kernel/exit.c to to kernel/kthread.c. As this function is kthread specific it makes most sense to live with the kthread functions. There are no functional change. Signed-off-by: "Eric W. Biederman"

usb: gadget: f_mass_storage: Disable eps during disconnect

2021-10-30T08:55:55Z

When receiving a disconnect event from the UDC, the mass storage function driver currently runs the handle_exception() routine asynchronously. For UDCs that support runtime PM, there is a possibility the UDC is already suspended by the time the do_set_interface() is executed. This can lead to HW register access while the UDC is already suspended.

usb: gadget: storage: add support for media larger than 2T

2021-10-10T13:07:56Z

This adds support for READ_CAPACITY(16), READ(16) and WRITE(16) commands, and fixes READ_CAPACITY command to return 0xffffffff if media size does not fit in 32 bits. This makes f_mass_storage to export a 16T disk array correctly.
