2021-04-22usb: dwc3: gadget: Fix START_TRANSFER link state checkThinh Nguyen
The START_TRANSFER command needs to be executed while in ON/U0 link state (with an exception during register initialization). Don't use dwc->link_state to check this since the driver only tracks the link state when the link state change interrupt is enabled. Check the link state from DSTS register instead. Note that often the host already brings the device out of low power before it sends/requests the next transfer. So, the user won't see any issue when the device starts transfer then. This issue is more noticeable in cases when the device delays starting transfer, which can happen during delayed control status after the host put the device in low power.

2021-04-22usb: gadget: Fix double free of device descriptor pointersHemant Kumar
Upon driver unbind usb_free_all_descriptors() function frees all speed descriptor pointers without setting them to NULL. In case gadget speed changes (i.e from super speed plus to super speed) after driver unbind only upto super speed descriptor pointers get populated. Super speed plus desc still holds the stale (already freed) pointer. Fix this issue by setting all descriptor pointers to NULL after freeing them in usb_free_all_descriptors().

2021-04-22nvme: introduce generic per-namespace chardevMinwoo Im
Userspace has not been allowed to I/O to device that's failed to be initialized. This patch introduces generic per-namespace character device to allow userspace to I/O regardless the block device is there or not. The chardev naming convention will similar to the existing blkdev naming, using a ng prefix instead of nvme, i.e. - /dev/ngXnY It also supports multipath which means it will not expose chardev for the hidden namespace blkdevs (e.g., nvmeXcYnZ). If /dev/ngXnY is created for a ns_head, then I/O request will be routed to a specific controller selected by the iopolicy of the subsystem.

The commit f1b206cf7c57 ("pinctrl: core: print gpio in pins debugfs file") enabled GPIO pin number and label in debugfs for pin controller. However, it limited that feature to the chips where base is positive number. This, in particular, excluded chips where base is 0 for the historical or backward compatibility reasons.

And according to the description, the two interfaces supported by X1830 are respectively referred to as "TFT interface" and "SLCD interface", so the "lcd-rgb-xxx" is replaced with "lcd-tft-xxx" to avoid confusion.

A switchdev RDMA device do not support IB CM. When such device is added to the RDMA CM's device list, when application invokes rdma_listen(), cma attempts to listen to such device, however it has IB CM attribute disabled. Due to this, rdma_listen() call fails to listen for other non switchdev devices as well. A below error message can be seen. infiniband mlx5_0: RDMA CMA: cma_listen_on_dev, error -38 A failing call flow is below. cma_listen_on_all() cma_listen_on_dev() _cma_attach_to_dev() rdma_listen() <- fails on a specific switchdev device This is because rdma_listen() is hardwired to only work with iwarp or IB CM compatible devices. Hence, when a IB device doesn't support IB CM or IW CM, avoid adding such device to the cma list so rdma_listen() can't even be called.

2021-04-21dm raid: fix inconclusive reshape layout on fast raid4/5/6 table reload ↵Heinz Mauelshagen
sequences If fast table reloads occur during an ongoing reshape of raid4/5/6 devices the target may race reading a superblock vs the the MD resync thread; causing an inconclusive reshape state to be read in its constructor. lvm2 test lvconvert-raid-reshape-stripes-load-reload.sh can cause BUG_ON() to trigger in md_run(), e.g.: "kernel BUG at drivers/md/raid5.c:7567!". Scenario triggering the bug: 1. the MD sync thread calls end_reshape() from raid5_sync_request() when done reshaping. However end_reshape() _only_ updates the reshape position to MaxSector keeping the changed layout configuration though (i.e. any delta disks, chunk sector or RAID algorithm changes). That inconclusive configuration is stored in the superblock. 2. dm-raid constructs a mapping, loading named inconsistent superblock as of step 1 before step 3 is able to finish resetting the reshape state completely, and calls md_run() which leads to mentioned bug in raid5.c. 3. the MD RAID personality's finish_reshape() is called; which resets the reshape information on chunk sectors, delta disks, etc. This explains why the bug is rarely seen on multi-core machines, as MD's finish_reshape() superblock update races with the dm-raid constructor's superblock load in step 2. Fix identifies inconclusive superblock content in the dm-raid constructor and resets it before calling md_run(), factoring out identifying checks into rs_is_layout_change() to share in existing rs_reshape_requested() and new rs_reset_inclonclusive_reshape(). Also enhance a comment and remove an empty line. Cc: stable@vger.kernel.org Signed-off-by: Heinz Mauelshagen <heinzm@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>

2021-04-21bonding: 3ad: Fix the conflict between bond_update_slave_arr and the state ↵jinyiting
machine The bond works in mode 4, and performs down/up operations on the bond that is normally negotiated. The probability of bond-> slave_arr is NULL Test commands: ifconfig bond1 down ifconfig bond1 up The conflict occurs in the following process: __dev_open (CPU A) --bond_open --queue_delayed_work(bond->wq,&bond->ad_work,0); --bond_update_slave_arr --bond_3ad_get_active_agg_info ad_work(CPU B) --bond_3ad_state_machine_handler --ad_agg_selection_logic ad_work runs on cpu B. In the function ad_agg_selection_logic, all agg->is_active will be cleared. Before the new active aggregator is selected on CPU B, bond_3ad_get_active_agg_info failed on CPU A, bond->slave_arr will be set to NULL. The best aggregator in ad_agg_selection_logic has not changed, no need to update slave arr. The conflict occurred in that ad_agg_selection_logic clears agg->is_active under mode_lock, but bond_open -> bond_update_slave_arr is inspecting agg->is_active outside the lock. Also, bond_update_slave_arr is normal for potential sleep when allocating memory, so replace the WARN_ON with a call to might_sleep.

pmc_core_lpm_latch_mode_write() The simple_write_to_buffer() can return success if even a single byte is copied from user space. In this case it can result in using uninitalized data if the buf[] array is not fully initialized. Really we should only succeed if the whole buffer is copied. Just using copy_from_user() is simpler and more appropriate.
