2020-03-10io_uring: support buffer selection for OP_READ and OP_RECVJens Axboe
If a server process has tons of pending socket connections, generally it uses epoll to wait for activity. When the socket is ready for reading (or writing), the task can select a buffer and issue a recv/send on the given fd. Now that we have fast (non-async thread) support, a task can have tons of pending reads or writes pending. But that means they need buffers to back that data, and if the number of connections is high enough, having them preallocated for all possible connections is unfeasible. With IORING_OP_PROVIDE_BUFFERS, an application can register buffers to use for any request. The request then sets IOSQE_BUFFER_SELECT in the sqe, and a given group ID in sqe->buf_group. When the fd becomes ready, a free buffer from the specified group is selected. If none are available, the request is terminated with -ENOBUFS. If successful, the CQE on completion will contain the buffer ID chosen in the cqe->flags member, encoded as: (buffer_id << IORING_CQE_BUFFER_SHIFT) | IORING_CQE_F_BUFFER; Once a buffer has been consumed by a request, it is no longer available and must be registered again with IORING_OP_PROVIDE_BUFFERS. Requests need to support this feature. For now, IORING_OP_READ and IORING_OP_RECV support it. This is checked on SQE submission, a CQE with res == -EOPNOTSUPP will be posted if attempted on unsupported requests. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-10io_uring: add IORING_OP_PROVIDE_BUFFERSJens Axboe
IORING_OP_PROVIDE_BUFFERS uses the buffer registration infrastructure to support passing in an addr/len that is associated with a buffer ID and buffer group ID. The group ID is used to index and lookup the buffers, while the buffer ID can be used to notify the application which buffer in the group was used. The addr passed in is the starting buffer address, and length is each buffer length. A number of buffers to add with can be specified, in which case addr is incremented by length for each addition, and each buffer increments the buffer ID specified. No validation is done of the buffer ID. If the application provides buffers within the same group with identical buffer IDs, then it'll have a hard time telling which buffer ID was used. The only restriction is that the buffer ID can be a max of 16-bits in size, so USHRT_MAX is the maximum ID that can be used. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2020-03-09net: mscc: ocelot: properly account for VLAN header length when setting MRUVladimir Oltean
What the driver writes into MAC_MAXLEN_CFG does not actually represent VLAN_ETH_FRAME_LEN but instead ETH_FRAME_LEN + ETH_FCS_LEN. Yes they are numerically equal, but the difference is important, as the switch treats VLAN-tagged traffic specially and knows to increase the maximum accepted frame size automatically. So it is always wrong to account for VLAN in the MAC_MAXLEN_CFG register. Unconditionally increase the maximum allowed frame size for double-tagged traffic. Accounting for the additional length does not mean that the other VLAN membership checks aren't performed, so there's no harm done. Also, stop abusing the MTU name for configuring the MRU. There is no support for configuring the MRU on an interface at the moment.

2020-03-09mtd: spinand: rework detect procedure for different READ_ID operationChuanhong Guo
Currently there are 3 different variants of read_id implementation: 1. opcode only. Found in GD5FxGQ4xF. 2. opcode + 1 addr byte. Found in GD5GxGQ4xA/E 3. opcode + 1 dummy byte. Found in other currently supported chips. Original implementation was for variant 1 and let detect function of chips with variant 2 and 3 to ignore the first byte. This isn't robust: 1. For chips of variant 2, if SPI master doesn't keep MOSI low during read, chip will get a random id offset, and the entire id buffer will shift by that offset, causing detect failure. 2. For chips of variant 1, if it happens to get a devid that equals to manufacture id of variant 2 or 3 chips, it'll get incorrectly detected. This patch reworks detect procedure to address problems above. New logic do detection for all variants separatedly, in 1-2-3 order. Since all current detect methods do exactly the same id matching procedure, unify them into core.c and remove detect method from manufacture_ops. Tested on GD5F1GQ4UAYIG and W25N01GVZEIG.

2020-03-08remoteproc: add IPA notification to q6v5 driverAlex Elder
Set up a subdev in the q6v5 modem remoteproc driver that generates event notifications for the IPA driver to use for initialization and recovery following a modem shutdown or crash. A pair of new functions provides a way for the IPA driver to register and deregister a notification callback function that will be called whenever modem events (about to boot, running, about to shut down, etc.) occur. A void pointer value (provided by the IPA driver at registration time) and an event type are supplied to the callback function. One event, MODEM_REMOVING, is signaled whenever the q6v5 driver is about to remove the notification subdevice. It requires the IPA driver de-register its callback. This sub-device is only used by the modem subsystem (MSS) driver, so the code that adds the new subdev and allows registration and deregistration of the notifier is found in "qcom_q6v6_mss.c".

But this works only for TCP sockets because for other socket types icsk parameter can be NULL and classid code path is skipped. This change moves classid handling to inet_diag_msg_attrs_fill() function. Also inet_diag_msg_attrs_size() helper was added and addends in nlmsg_new() were reordered to save order from inet_sk_diag_fill().

2020-03-08sched: act: allow user to specify type of HW stats for a filterJiri Pirko
Currently, user who is adding an action expects HW to report stats, however it does not have exact expectations about the stats types. That is aligned with TCA_ACT_HW_STATS_TYPE_ANY. Allow user to specify the type of HW stats for an action and require it. Pass the information down to flow_offload layer. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2020-03-08flow_offload: Introduce offload of HW stats typeJiri Pirko
Initially, pass "ANY" (struct is zeroed) to the drivers as that is the current implicit value coming down to flow_offload. Add a bool indicating that entries have mixed HW stats type. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-08iio: industrialio-core: Fix debugfs readAlexandru Tachici
Currently iio_debugfs_read_reg calls debugfs_reg_access every time it is ran. Reading the same hardware register multiple times during the same reading of a debugfs file can cause unintended effects. For example for each: cat iio:device0/direct_reg_access the file_operations.read function will be called at least twice. First will return the full length of the string in bytes and the second will return 0. This patch makes iio_debugfs_read_reg to call debugfs_reg_access only when the user's buffer position (*ppos) is 0. (meaning it is the beginning of a new reading of the debugfs file).
