usb: gadget: configfs: clear deactivation flag in configfs_composite_unbind()

2022-05-12T10:14:54+00:00

commit bf95c4d4630c7a2c16e7b424fdea5177d9ce0864 upstream.

If any function like UVC is deactivating gadget as part of composition
switch which results in not calling pullup enablement, it is not getting
enabled after switch to new composition due to this deactivation flag
not cleared. This results in USB enumeration not happening after switch
to new USB composition. Hence clear deactivation flag inside gadget
structure in configfs_composite_unbind() before switch to new USB
composition.

usb: gadget: uvc: Fix crash when encoding data for usb request

2022-05-12T10:14:54+00:00

commit 71d471e3faf90c9674cadc7605ac719e82cb7fac upstream.

During the uvcg_video_pump() process, if an error occurs and
uvcg_queue_cancel() is called, the buffer queue will be cleared out, but
the current marker (queue->buf_used) of the active buffer (no longer
active) is not reset. On the next iteration of uvcg_video_pump() the
stale buf_used count will be used and the logic of min((unsigned
int)len, buf->bytesused - queue->buf_used) may incorrectly calculate a
nbytes size, causing an invalid memory access.

usb: misc: fix improper handling of refcount in uss720_probe()

2022-05-12T10:14:54+00:00

commit 0a96fa640dc928da9eaa46a22c46521b037b78ad upstream.

usb_put_dev shouldn't be called when uss720_probe succeeds because of
priv->usbdev. At the same time, priv->usbdev shouldn't be set to NULL
before destroy_priv in uss720_disconnect because usb_put_dev is in
destroy_priv.

Fix this by moving priv->usbdev = NULL after usb_put_dev.

xhci: stop polling roothubs after shutdown

2022-05-12T10:14:53+00:00

commit dc92944a014cd6a6f6c94299aaa36164dd2c238a upstream.

While rebooting, XHCI controller and its bus device will be shut down
in order by .shutdown callback. Stopping roothubs polling in
xhci_shutdown() can prevent XHCI driver from accessing port status
after its bus device shutdown.

Take PCIe XHCI controller as example, if XHCI driver doesn't stop roothubs
polling, XHCI driver may access PCIe BAR register for port status after
parent PCIe root port driver is shutdown and cause PCIe bus error.

[check shared hcd exist before stopping its roothub polling -Mathias]

USB: serial: whiteheat: fix heap overflow in WHITEHEAT_GET_DTR_RTS

2022-05-12T10:14:53+00:00

commit e23e50e7acc8d8f16498e9c129db33e6a00e80eb upstream.

The sizeof(struct whitehat_dr_info) can be 4 bytes under CONFIG_AEABI=n
due to "-mabi=apcs-gnu", even though it has a single u8:

whiteheat_private {
        __u8                       mcr;                  /*     0     1 */

        /* size: 4, cachelines: 1, members: 1 */
        /* padding: 3 */
        /* last cacheline: 4 bytes */
};

The result is technically harmless, as both the source and the
destinations are currently the same allocation size (4 bytes) and don't
use their padding, but if anything were to ever be added after the
"mcr" member in "struct whiteheat_private", it would be overwritten. The
structs both have a single u8 "mcr" member, but are 4 bytes in padded
size. The memcpy() destination was explicitly targeting the u8 member
(size 1) with the length of the whole structure (size 4), triggering
the memcpy buffer overflow warning:

                 from include/linux/bitmap.h:11,

Instead, just assign the one byte directly.
