This patch fixes the following issues: 1. memstick_free_host() will free the host, so the use of ms_dev(host) after it will be a problem. To fix this, move memstick_free_host() after when we are done with ms_dev(host). 2. In rtsx_usb_ms_drv_remove(), pm need to be disabled before we remove and free host otherwise memstick_check will be called and UAF will happen.

2021-06-14mmc: core: Add support for cache ctrl for SD cardsUlf Hansson3-0/+102
In SD spec v6.x the SD function extension registers for performance enhancements were introduced. As a part of this an optional internal cache on the SD card, can be used to improve performance. The let the SD card use the cache, the host needs to enable it and manage flushing of the cache, so let's add support for this. Note that for an SD card supporting the cache it's mandatory for it, to also support the poweroff notification feature. According to the SD spec, if the cache has been enabled and a poweroff notification is sent to the card, that implicitly also means that the card should flush its internal cache. Therefore, dealing with cache flushing for REQ_OP_FLUSH block requests is sufficient.

2021-06-14mmc: core: Enable eMMC sleep commands to use HW busy pollingUlf Hansson1-5/+20
After the eMMC sleep command (CMD5) has been sent, the card start signals busy on the DAT0 line, which can be monitored to understand when it's allowed to proceed to power off the VCC regulator. When MMC_CAP_WAIT_WHILE_BUSY isn't supported by the host the DAT0 line isn't being monitored for busy completion, but instead we are waiting a fixed period of time. The time corresponds to the sleep timeout that is specified in the EXT_CSD register of the eMMC card. This is many cases suboptimal, as the timeout corresponds to the worst case scenario. To improve the situation add support for HW busy polling through the ->card_busy() host ops, when the host supports this.

More precisely, let __mmc_poll_for_busy() take a pointer to a callback function as in-parameter, which it calls to poll for busy state completion.

Commit c76f48eb5c08 ("block: take bd_mutex around delete_partitions in del_gendisk") adds disk->part0->bd_mutex in del_gendisk(), this way causes the following AB/BA deadlock between removing loop and opening loop: 1) loop_control_ioctl(LOOP_CTL_REMOVE) -> mutex_lock(&loop_ctl_mutex) -> del_gendisk -> mutex_lock(&disk->part0->bd_mutex) 2) blkdev_get_by_dev -> mutex_lock(&disk->part0->bd_mutex) -> lo_open -> mutex_lock(&loop_ctl_mutex) Add a new Lo_deleting state to remove the need for clearing ->private_data and thus holding loop_ctl_mutex in the ioctl LOOP_CTL_REMOVE path.

Fix the copy-paste mistake in the return path of typec_mux_match(), where dev is considered a member of struct typec_switch rather than struct typec_mux. The two structs are identical in regards to having the struct device as the first entry, so this provides no functional change.

2021-06-10usb: typec: ucsi: Clear PPM capability data in ucsi_init() error pathMayank Rana1-0/+1
If ucsi_init() fails for some reason (e.g. ucsi_register_port() fails or general communication failure to the PPM), particularly at any point after the GET_CAPABILITY command had been issued, this results in unwinding the initialization and returning an error. However the ucsi structure's ucsi_capability member retains its current value, including likely a non-zero num_connectors. And because ucsi_init() itself is done in a workqueue a UCSI interface driver will be unaware that it failed and may think the ucsi_register() call was completely successful. Later, if ucsi_unregister() is called, due to this stale ucsi->cap value it would try to access the items in the ucsi->connector array which might not be in a proper state or not even allocated at all and results in NULL or invalid pointer dereference. Fix this by clearing the ucsi->cap value to 0 during the error path of ucsi_init() in order to prevent a later ucsi_unregister() from entering the connector cleanup loop.

2021-06-10usb: gadget: fsl: Re-enable driver for ARM SoCsJoel Stanley1-1/+1
The commit a390bef7db1f ("usb: gadget: fsl_mxc_udc: Remove the driver") dropped the ARCH_MXC dependency from USB_FSL_USB2, leaving it depending solely on FSL_SOC. FSL_SOC is powerpc only; it was briefly available on ARM in 2014 but was removed by commit cfd074ad8600 ("ARM: imx: temporarily remove CONFIG_SOC_FSL from LS1021A"). Therefore the driver can no longer be enabled on ARM platforms. This appears to be a mistake as arm64's ARCH_LAYERSCAPE and arm32 SOC_LS1021A SoCs use this symbol. It's enabled in these defconfigs: arch/arm/configs/imx_v6_v7_defconfig:CONFIG_USB_FSL_USB2=y arch/arm/configs/multi_v7_defconfig:CONFIG_USB_FSL_USB2=y arch/powerpc/configs/mgcoge_defconfig:CONFIG_USB_FSL_USB2=y arch/powerpc/configs/mpc512x_defconfig:CONFIG_USB_FSL_USB2=y To fix, expand the dependencies so USB_FSL_USB2 can be enabled on the ARM platforms, and with COMPILE_TEST.
