2021-08-16nvme: code command_id with a genctr for use-after-free validationSagi Grimberg
We cannot detect a (perhaps buggy) controller that is sending us a completion for a request that was already completed (for example sending a completion twice), this phenomenon was seen in the wild a few times. So to protect against this, we use the upper 4 msbits of the nvme sqe command_id to use as a 4-bit generation counter and verify it matches the existing request generation that is incrementing on every execution. The 16-bit command_id structure now is constructed by: | xxxx | xxxxxxxxxxxx | gen request tag This means that we are giving up some possible queue depth as 12 bits allow for a maximum queue depth of 4095 instead of 65536, however we never create such long queues anyways so no real harm done.

2021-08-16spi: orion: Prevent incorrect chip select behaviourNathan Rossi
When clearing the chip-select mask, the controller will switch to chip selecting the native CS0 line. Because the control register chip-select mask is not updated in a single write this will cause undesirable chip-selection of CS0 even when requesting to select other native chip-select lines. This is additionally problematic as the chip-select may still be asserted. With the ARMADA 38x SoC the controller will assert both the desired native chip-select and CS0. To avoid any undesirable behaviour with the chip-select lines, update the control register with a single write. This avoids selecting CS0 and causes the (de-)assert to apply at the same time.

In 69de4421bb4c ("drm/ttm: Initialize debugfs from ttm_global_init()"), ttm_global_init was changed so that if creation of the debugfs global root directory fails, ttm_global_init will bail out early and return an error, leading to initialization failure of DRM drivers. However, not every system will be using debugfs. On such a system, debugfs directory creation can be expected to fail, but DRM drivers must still be usable. This changes it so that if creation of TTM's debugfs root directory fails, then no biggie: keep calm and carry on.

2021-08-16bnxt_en: Add missing DMA memory barriersMichael Chan
Each completion ring entry has a valid bit to indicate that the entry contains a valid completion event. The driver's main poll loop __bnxt_poll_work() has the proper dma_rmb() to make sure the valid bit of the next entry has been checked before proceeding further. But when we call bnxt_rx_pkt() to process the RX event, the RX completion event consists of two completion entries and only the first entry has been checked to be valid. We need the same barrier after checking the next completion entry. Add missing dma_rmb() barriers in bnxt_rx_pkt() and other similar locations.

Lightnvm supports the OCSSD 1.x and 2.0 specs which were early attempts to produce Open Channel SSDs and never made it into the NVMe spec proper. They have since been superceeded by NVMe enhancements such as ZNS support. Remove the support per the deprecation schedule.
