2022-01-07RDMA/rtrs-srv: Rename rtrs_srv to rtrs_srv_sessVaishali Thakkar6-42/+43
Structure rtrs_srv is used for sessions so in order to avoid confusions rename it to rtrs_srv_sess. All changes were done with the help of following Coccinelle script: @@ @@ struct - rtrs_srv + rtrs_srv_sess Link: https://lore.kernel.org/r/20220105180708.7774-5-jinpu.wang@ionos.com Signed-off-by: Vaishali Thakkar <vaishali.thakkar@ionos.com> Signed-off-by: Jack Wang <jinpu.wang@ionos.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

rtrs_clt_sess is used for paths and not sessions on the client side. This creates confusion so let's rename it to rtrs_clt_path. Also, rename related variables and functions. Coccinelle is used to do the transformations for most of the occurrences and remaining ones were handled manually.

2022-01-05IB/iser: Don't suppress send completionsMax Gurtovoy3-20/+6
In order to complete a scsi command and guarantee that the HCA will never perform an access violation when retrying a send operation we must complete a scsi request only when both send and receive completions has arrived. This is a preparation commit that remove the send completions suppression. Next step will be taking care of the local invalidation mechanism and adding a reference counter for commands. Currently, we don't do anything upon getting the send completion and just "consume" it.

2022-01-05IB/iser: Fix RNR errorsSergey Gorenko3-78/+42
Some users complain about RNR errors on the target, when heavy high-priority tasks run on the initiator. After the investigation, we found out that the receive WRs were exhausted, because the initiator could not post them on time. Receive work reqeusts are posted in chunks to reduce the number of hits to the HCA. The WRs are posted in the receive completion handler when the number of free receive buffers reaches the threshold. But on a high-loaded host, receive CQEs processing can be delayed and all receive WRs will be exhausted. In this case, the target will get an RNR error. To avoid this, we post receive WR, as soon as possible and not in a batch. This increases the number of hits to the HCA, but also the common implementation in most of Linux ULPs (e.g. NVMe-oF/RDMA). As a rule of thumb, performance improvements and heuristics are being added to the RDMA core layer or vendors low level drivers and it's about time to align iSER as well.

Currently, when cma_resolve_ib_dev() searches for a matching GID it will stop searching after encountering the first empty GID table entry. This behavior is wrong since neither IB nor RoCE spec enforce tightly packed GID tables. For example, when the matching valid GID entry exists at index N, and if a GID entry is empty at index N-1, cma_resolve_ib_dev() will fail to find the matching valid entry.

In the case of light load, the wqe will be filled into pcie bar space of the hardware, this will reduce one memory access operation and therefore reduce the latency. SIMD instructions allows cpu to write the 512 bits at one time to device memory, thus it can be used for posting direct wqe. Add direct wqe enable switch and address mapping.

Using standard USB_EP_MAXP_MULT_MASK instead of individual bits for extracting multiple-transactions bits from wMaxPacketSize value.

2021-12-12usb: core: config: fix validation of wMaxPacketValue entriesPavel Hofman1-1/+1
The checks performed by commit aed9d65ac327 ("USB: validate wMaxPacketValue entries in endpoint descriptors") require that initial value of the maxp variable contains both maximum packet size bits (10..0) and multiple-transactions bits (12..11). However, the existing code assings only the maximum packet size bits. This patch assigns all bits of wMaxPacketSize to the variable.

2021-12-12USB: gadget: zero allocate endpoint 0 buffersGreg Kroah-Hartman2-2/+2
Under some conditions, USB gadget devices can show allocated buffer contents to a host. Fix this up by zero-allocating them so that any extra data will all just be zeros.

2021-12-12USB: gadget: detect too-big endpoint 0 requestsGreg Kroah-Hartman3-1/+40
Sometimes USB hosts can ask for buffers that are too large from endpoint 0, which should not be allowed. If this happens for OUT requests, stall the endpoint, but for IN requests, trim the request size to the endpoint buffer size.

Pull xfs fix from Darrick Wong: "This fixes a race between a readonly remount process and other processes that hold a file IOLOCK on files that previously experienced copy on write, that could result in severe filesystem corruption if the filesystem is then remounted rw. I think this is fairly rare (since the only reliable reproducer I have that fits the second criteria is the experimental xfs_scrub program), but the race is clear, so we still need to fix this. Summary: - Fix a data corruption vector that can result from the ro remount process failing to clear all speculative preallocations from files and the rw remount process not noticing the incomplete cleanup" * tag 'xfs-5.16-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: remove all COW fork extents when remounting readonly

It seems in the past they have gotten away with it due to mapping of vm functions to km functions, but this fell apart a few releases ago and was just reported recently. The other is just a minor dependency clean up. I think queued up right now by Andrew is a fix in percpu that papers of what seems to be a bug in hotplug for a special situation with memoryless nodes.
