While handling the completion queue, keep a local copy of the command id from the DMA-accessible completion entry. This silences a time-of-check to time-of-use (TOCTOU) warning from KF/x[1], with respect to a Thunderclap[2] vulnerability analysis. The double-read impact appears benign. There may be a theoretical window for @command_id to be used as an adversary-controlled array-index-value for mounting a speculative execution attack, but that mitigation is saved for a potential follow-on. A man-in-the-middle attack on the data payload is out of scope for this analysis and is hopefully mitigated by filesystem integrity mechanisms.

We may send a request (with or without its data) from two paths: 1. From our I/O context nvme_tcp_io_work which is triggered from: - queue_rq - r2t reception - socket data_ready and write_space callbacks 2. Directly from queue_rq if the send_list is empty (because we want to save the context switch associated with scheduling our io_work). However, given that now we have the send_mutex, we may run into a race condition where none of these contexts will send the pending payload to the controller. Both io_work send path and queue_rq send path opportunistically attempt to acquire the send_mutex however queue_rq only attempts to send a single request, and if io_work context fails to acquire the send_mutex it will complete without rescheduling itself. The race can trigger with the following sequence: 1. queue_rq sends request (no incapsule data) and blocks 2. RX path receives r2t - prepares data PDU to send, adds h2cdata PDU to the send_list and schedules io_work 3. io_work triggers and cannot acquire the send_mutex - because of (1), ends without self rescheduling 4. queue_rq completes the send, and completes ==> no context will send the h2cdata - timeout. Fix this by having queue_rq sending as much as it can from the send_list such that if it still has any left, its because the socket buffer is full and the socket write_space callback will trigger, thus guaranteeing that a context will be scheduled to send the h2cdata PDU. Fixes: db5ad6b7 ("nvme-tcp: try to send request in queue_rq context") Reported-by:

Recent patches changed calling sequences. nvme_fc_abort_outstanding_ios used to be called from a timeout or work context. Now it is being called in an io completion context, which can be an interrupt handler. Unfortunately, the abort outstanding ios routine attempts to stop nvme queues and nested routines that may try to sleep, which is in conflict with the interrupt handler. Correct replacing the direct call with a work element scheduling, and the abort outstanding ios routine will be called in the work element.

BFQ computes number of tags it allows to be allocated for each request type based on tag bitmap. However it uses 1 << bitmap.shift as number of available tags which is wrong. 'shift' is just an internal bitmap value containing logarithm of how many bits bitmap uses in each bitmap word. Thus number of tags allowed for some request types can be far to low. Use proper bitmap.depth which has the number of tags instead. Signed-off-by:

When initializing iocost for a queue, its rqos should be registered before the blkcg policy is activated to allow policy data initiailization to lookup the associated ioc. This unfortunately means that the rqos methods can be called on bios before iocgs are attached to all existing blkgs. While the race is theoretically possible on ioc_rqos_throttle(), it mostly happened in ioc_rqos_merge() due to the difference in how they lookup ioc. The former determines it from the passed in @rqos and then bails before dereferencing iocg if the looked up ioc is disabled, which most likely is the case if initialization is still in progress. The latter looked up ioc by dereferencing the possibly NULL iocg making it a lot more prone to actually triggering the bug. * Make ioc_rqos_merge() use the same method as ioc_rqos_throttle() to look up ioc for consistency. * Make ioc_rqos_throttle() and ioc_rqos_merge() test for NULL iocg before dereferencing it. * Explain the danger of NULL iocgs in blk_iocost_init().

Since commit 36e2c742 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d..b24c30c6 , but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends. Reported-by:

The fix is to move Tegra's link up handling to .start_link() function like other DWC drivers. Tegra is a bit more complicated than others as it re-inits the whole DWC controller to retry the link. With this, the initialization ordering is restored to match the prior sequence.
