2022-12-06net: mana: Fix race on per-CQ variable napi work_doneHaiyang Zhang2-6/+19
After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be cleared, and another CPU can start napi thread and access per-CQ variable, cq->work_done. If the other thread (for example, from busy_poll) sets it to a value >= budget, this thread will continue to run when it should stop, and cause memory corruption and panic. To fix this issue, save the per-CQ work_done variable in a local variable before napi_complete_done(), so it won't be corrupted by a possible concurrent thread after napi_complete_done(). Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done variable race is fixed, so the driver is able to reliably support features like busy_poll.

Our mpath stack device is just a shim that selects a bottom namespace and submits the bio to it without any fancy splitting. This also means that we don't clone the bio or have any context to the bio beyond submission. However it really sucks that we don't see the mpath device io stats. Given that the mpath device can't do that without adding some context to it, we let the bottom device do it on its behalf (somewhat similar to the approach taken in nvme_trace_bio_complete). When the IO starts, we account the request for multipath IO stats using REQ_NVME_MPATH_IO_STATS nvme_request flag to avoid queue io stats disable in the middle of the request.

2022-12-06nvme: introduce nvme_start_requestSagi Grimberg7-6/+11
In preparation for nvme-multipath IO stats accounting, we want the accounting to happen in a centralized place. The request completion is already centralized, but we need a common helper to request I/O start.

2022-12-06nvme: use kstrtobool() instead of strtobool()Christophe JAILLET2-9/+11
strtobool() is the same as kstrtobool(). However, the latter is more used within the kernel. In order to remove strtobool() and slightly simplify kstrtox.h, switch to the other function name. While at it, include the corresponding header file (<linux/kstrtox.h>) Signed-off-by: Christophe JAILLET <[email protected]> Signed-off-by: Christoph Hellwig <[email protected]>
2022-12-06nvme: don't call blk_mq_{,un}quiesce_tagset when ctrl->tagset is NULLChristoph Hellwig1-0/+4
The NVMe drivers support a mode where no tagset is allocated for the I/O queues and only the admin queue is usable. In that case ctrl->tagset is NULL and we must not call the block per-tagset quiesce helpers that dereference it.

2022-12-06nvme initialize core quirks before calling nvme_init_subsystemPankaj Raghav1-4/+4
A device might have a core quirk for NVME_QUIRK_IGNORE_DEV_SUBNQN (such as Samsung X5) but it would still give a: "missing or invalid SUBNQN field" warning as core quirks are filled after calling nvme_init_subnqn. Fill ctrl->quirks from struct core_quirks before calling nvme_init_subsystem to fix this. Tested on a Samsung X5.
