2019-09-03usb: common: add USB GPIO based connection detection driverChunfeng Yun
Due to the requirement of usb-connector.txt binding, the old way using extcon to support USB Dual-Role switch is now deprecated when use Type-B connector. This patch introduces a USB GPIO based connection detection driver, used to support Type-B connector which typically uses an input GPIO to detect USB ID pin, and try to replace the function provided by the extcon-usb-gpio driver Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Tested-by: Nagarjuna Kristam <nkristam@nvidia.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Link: https://lore.kernel.org/r/1567070558-29417-11-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-09-03Revert "mmc: core: do not retry CMD6 in __mmc_switch()"Jan Kaisrlik
Turns out the commit 3a0681c7448b ("mmc: core: do not retry CMD6 in __mmc_switch()") breaks initialization of a Toshiba THGBMNG5 eMMC card, when using the meson-gx-mmc.c driver on a custom board based on Amlogic A113D. The CMD6 that switches the card into HS200 mode is then one that fails and according to the below printed messages from the log: [ 1.648951] mmc0: mmc_select_hs200 failed, error -84 [ 1.648988] mmc0: error -84 whilst initialising MMC card After some analyze, it turns out that adding a delay of ~5ms inside mmc_select_bus_width() but after mmc_compare_ext_csds() has been executed, also fixes the problem. Adding yet some more debug code, trying to figure out if potentially the card could be in a busy state, both by using CMD13 and ->card_busy() ops concluded that this was not the case. Therefore, let's simply revert the commit that dropped support for retrying of CMD6, as this also fixes the problem.

2019-09-03closures: fix a race on wakeup from closure_syncKent Overstreet
The race was when a thread using closure_sync() notices cl->s->done == 1 before the thread calling closure_put() calls wake_up_process(). Then, it's possible for that thread to return and exit just before wake_up_process() is called - so we're trying to wake up a process that no longer exists. rcu_read_lock() is sufficient to protect against this, as there's an rcu barrier somewhere in the process teardown path.

2019-09-03usbip: Implement SG support to vhci-hcd and stub driverSuwan Kim
There are bugs on vhci with usb 3.0 storage device. In USB, each SG list entry buffer should be divisible by the bulk max packet size. But with native SG support, this problem doesn't matter because the SG buffer is treated as contiguous buffer. But without native SG support, USB storage driver breaks SG list into several URBs and the error occurs because of a buffer size of URB that cannot be divided by the bulk max packet size. The error situation is as follows. When USB Storage driver requests 31.5 KB data and has SG list which has 3584 bytes buffer followed by 7 4096 bytes buffer for some reason. USB Storage driver splits this SG list into several URBs because VHCI doesn't support SG and sends them separately. So the first URB buffer size is 3584 bytes. When receiving data from device, USB 3.0 device sends data packet of 1024 bytes size because the max packet size of BULK pipe is 1024 bytes. So device sends 4096 bytes. But the first URB buffer has only 3584 bytes buffer size. So host controller terminates the transfer even though there is more data to receive. So, vhci needs to support SG transfer to prevent this error. In this patch, vhci supports SG regardless of whether the server's host controller supports SG or not, because stub driver splits SG list into several URBs if the server's host controller doesn't support SG. To support SG, vhci sets URB_DMA_MAP_SG flag in urb->transfer_flags if URB has SG list and this flag will tell stub driver to use SG list. After receiving urb from stub driver, vhci clear URB_DMA_MAP_SG flag to avoid unnecessary DMA unmapping in HCD. vhci sends each SG list entry to stub driver. Then, stub driver sees the total length of the buffer and allocates SG table and pages according to the total buffer length calling sgl_alloc(). After stub driver receives completed URB, it again sends each SG list entry to vhci. If the server's host controller doesn't support SG, stub driver breaks a single SG request into several URBs and submits them to the server's host controller. When all the split URBs are completed, stub driver reassembles the URBs into a single return command and sends it to vhci. Moreover, in the situation where vhci supports SG, but stub driver does not, or vice versa, usbip works normally. Because there is no protocol modification, there is no problem in communication between server and client even if the one has a kernel without SG support. In the case of vhci supports SG and stub driver doesn't, because vhci sends only the total length of the buffer to stub driver as it did before the patch applied, stub driver only needs to allocate the required length of buffers using only kmalloc() regardless of whether vhci supports SG or not. But stub driver has to allocate buffer with kmalloc() as much as the total length of SG buffer which is quite huge when vhci sends SG request, so it has overhead in buffer allocation in this situation. If stub driver needs to send data buffer to vhci because of IN pipe, stub driver also sends only total length of buffer as metadata and then sends real data as vhci does. Then vhci receive data from stub driver and store it to the corresponding buffer of SG list entry. And for the case of stub driver supports SG and vhci doesn't, since the USB storage driver checks that vhci doesn't support SG and sends the request to stub driver by splitting the SG list into multiple URBs, stub driver allocates a buffer for each URB with kmalloc() as it did before this patch. * Test environment Test uses two difference machines and two different kernel version to make mismatch situation between the client and the server where vhci supports SG, but stub driver does not, or vice versa. All tests are conducted in both full SG support that both vhci and stub support SG and half SG support that is the mismatch situation. Test kernel version is 5.3-rc6 with commit "usb: add a HCD_DMA flag instead of guestimating DMA capabilities" to avoid unnecessary DMA mapping and unmapping. - Test kernel version - 5.3-rc6 with SG support - 5.1.20-200.fc29.x86_64 without SG support * SG support test - Test devices - Super-speed storage device - SanDisk Ultra USB 3.0 - High-speed storage device - SMI corporation USB 2.0 flash drive - Test description Test read and write operation of mass storage device that uses the BULK transfer.

2019-09-03block: mq-deadline: Fix queue restart handlingDamien Le Moal
Commit 7211aef86f79 ("block: mq-deadline: Fix write completion handling") added a call to blk_mq_sched_mark_restart_hctx() in dd_dispatch_request() to make sure that write request dispatching does not stall when all target zones are locked. This fix left a subtle race when a write completion happens during a dispatch execution on another CPU: CPU 0: Dispatch CPU1: write completion dd_dispatch_request() lock(&dd->lock); ... lock(&dd->zone_lock); dd_finish_request() rq = find request lock(&dd->zone_lock); unlock(&dd->zone_lock); zone write unlock unlock(&dd->zone_lock); ... __blk_mq_free_request check restart flag (not set) -> queue not run ... if (!rq && have writes) blk_mq_sched_mark_restart_hctx() unlock(&dd->lock) Since the dispatch context finishes after the write request completion handling, marking the queue as needing a restart is not seen from __blk_mq_free_request() and blk_mq_sched_restart() not executed leading to the dispatch stall under 100% write workloads. Fix this by moving the call to blk_mq_sched_mark_restart_hctx() from dd_dispatch_request() into dd_finish_request() under the zone lock to ensure full mutual exclusion between write request dispatch selection and zone unlock on write request completion.

2019-09-03rsi: fix a double free bug in rsi_91x_deinit()Hui Peng
`dev` (struct rsi_91x_usbdev *) field of adapter (struct rsi_91x_usbdev *) is allocated and initialized in `rsi_init_usb_interface`. If any error is detected in information read from the device side, `rsi_init_usb_interface` will be freed. However, in the higher level error handling code in `rsi_probe`, if error is detected, `rsi_91x_deinit` is called again, in which `dev` will be freed again, resulting double free. This patch fixes the double free by removing the free operation on `dev` in `rsi_init_usb_interface`, because `rsi_91x_deinit` is also used in `rsi_disconnect`, in that code path, the `dev` field is not (and thus needs to be) freed. This bug was found in v4.19, but is also present in the latest version of kernel. Fixes CVE-2019-15504.
