2022-07-27net: dsa: mv88e6xxx: fix speed setting for CPU/DSA portsMarcin Wojtas
Commit 3c783b83bd0f ("net: dsa: mv88e6xxx: get rid of SPEED_MAX setting") stopped relying on SPEED_MAX constant and hardcoded speed settings for the switch ports and rely on phylink configuration. It turned out, however, that when the relevant code is called, the mac_capabilites of CPU/DSA port remain unset. mv88e6xxx_setup_port() is called via mv88e6xxx_setup() in dsa_tree_setup_switches(), which precedes setting the caps in phylink_get_caps down in the chain of dsa_tree_setup_ports(). As a result the mac_capabilites are 0 and the default speed for CPU/DSA port is 10M at the start. To fix that, execute mv88e6xxx_get_caps() and obtain the capabilities driectly.

2022-07-28mtd: spi-nor: spansion: Add s25hl-t/s25hs-t IDs and fixupsTakahiro Kuwano
The S25HL-T/S25HS-T family is the Infineon SEMPER Flash with Quad SPI. These Infineon chips support volatile version of configuration registers and it is recommended to update volatile registers in the field application due to a risk of the non-volatile registers corruption by power interrupt. Add support for volatile QE bit. For the single-die package parts (512Mb and 1Gb), only bottom 4KB and uniform sector sizes are supported. This is due to missing or incorrect entries in SMPT. Fixup for other sector sizes configurations will be followed up as needed. Tested on Xilinx Zynq-7000 FPGA board.

2022-07-28mtd: spi-nor: core: Track flash's internal address modeTudor Ambarus
We need to track the flash's internal address mode as there are flashes that can operate with 4B opcodes but unfortunately do not have a 4B opcode correspondent for all the 3B opcodes. Such an example is the Infineon Semper chips which provide 4B opcodes for read/program/erase but do not provide 4B opcodes for Read/Write Any Register. These registers are indexed by address and require the internal address mode of the flash before Read/Write Any Register opcodes are issued. 4B opcodes are preferred over changing the flash's address mode to 4byte, as set_4byte_addr_mode could be done in a non-volatile way and could break the boot sequence. Thus we need to track the flash's internal address mode so that we can use 4B opcodes together with opcodes that don't have a 4B opcode correspondent. Track flash's internal address mode. addr_mode_nbytes is discovered when parsing BFPT. For the BFPT_DWORD1_ADDRESS_BYTES_3_OR_4 case, one could introduce a method that queries the flash's internal address mode at run-time (works for Winbond). If a run-time querying can not be accomplished or if SFDP is not defined at all, but the address mode is volatile and resets to a default known value at boot, one can change the default addr_mode_nbytes value of 3 by introducing a flash_info flag. If the address mode can not be queried, discovered and it is configured via a non-volatile register, we may introduce a dt property, but it will harm the generic approach of the jedec,spi-nor compatible. All this complexity is not needed now, so let it for future development.

2022-07-27sctp: leave the err path free in sctp_stream_init to sctp_stream_freeXin Long
A NULL pointer dereference was reported by Wei Chen: BUG: kernel NULL pointer dereference, address: 0000000000000000 RIP: 0010:__list_del_entry_valid+0x26/0x80 Call Trace: <TASK> sctp_sched_dequeue_common+0x1c/0x90 sctp_sched_prio_dequeue+0x67/0x80 __sctp_outq_teardown+0x299/0x380 sctp_outq_free+0x15/0x20 sctp_association_free+0xc3/0x440 sctp_do_sm+0x1ca7/0x2210 sctp_assoc_bh_rcv+0x1f6/0x340 This happens when calling sctp_sendmsg without connecting to server first. In this case, a data chunk already queues up in send queue of client side when processing the INIT_ACK from server in sctp_process_init() where it calls sctp_stream_init() to alloc stream_in. If it fails to alloc stream_in all stream_out will be freed in sctp_stream_init's err path. Then in the asoc freeing it will crash when dequeuing this data chunk as stream_out is missing. As we can't free stream out before dequeuing all data from send queue, and this patch is to fix it by moving the err path stream_out/in freeing in sctp_stream_init() to sctp_stream_free() which is eventually called when freeing the asoc in sctp_association_free(). This fix also makes the code in sctp_process_init() more clear. Note that in sctp_association_init() when it fails in sctp_stream_init(), sctp_association_free() will not be called, and in that case it should go to 'stream_free' err path to free stream instead of 'fail_init'.

2022-07-27sfc: disable softirqs for ptp TXAlejandro Lucero
Sending a PTP packet can imply to use the normal TX driver datapath but invoked from the driver's ptp worker. The kernel generic TX code disables softirqs and preemption before calling specific driver TX code, but the ptp worker does not. Although current ptp driver functionality does not require it, there are several reasons for doing so: 1) The invoked code is always executed with softirqs disabled for non PTP packets. 2) Better if a ptp packet transmission is not interrupted by softirq handling which could lead to high latencies. 3) netdev_xmit_more used by the TX code requires preemption to be disabled. Indeed a solution for dealing with kernel preemption state based on static kernel configuration is not possible since the introduction of dynamic preemption level configuration at boot time using the static calls functionality.

Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

2022-07-27Merge branch 'erdma' into rdma.git for-nextJason Gunthorpe
Cheng Xu says ==================== This v14 patch set introduces the Elastic RDMA Adapter (ERDMA) driver, which released in Apsara Conference 2021 by Alibaba. The PR of ERDMA userspace provider has already been created [1]. ERDMA enables large-scale RDMA acceleration capability in Alibaba ECS environment, initially offered in g7re instance. It can improve the efficiency of large-scale distributed computing and communication significantly and expand dynamically with the cluster scale of Alibaba Cloud. ERDMA is a RDMA networking adapter based on the Alibaba MOC hardware. It works in the VPC network environment (overlay network), and uses iWarp transport protocol. ERDMA supports reliable connection (RC). ERDMA also supports both kernel space and user space verbs. Now we have already supported HPC/AI applications with libfabric, NoF and some other internal verbs libraries, such as xrdma, epsl, etc,. For the ECS instance with RDMA enabled, our MOC hardware generates two kinds of PCI devices: one for ERDMA, and one for the original net device (virtio-net). They are separated PCI devices. ==================== * branch 'erdma': RDMA/erdma: Add driver to kernel build environment RDMA/erdma: Add the ABI definitions RDMA/erdma: Add the erdma module RDMA/erdma: Add connection management (CM) support RDMA/erdma: Add verbs implementation RDMA/erdma: Add verbs header file RDMA/erdma: Add event queue implementation RDMA/erdma: Add cmdq implementation RDMA/erdma: Add main include file RDMA/erdma: Add the hardware related definitions RDMA: Add ERDMA to rdma_driver_id definition Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

ERDMA's transport protocol is iWarp, so the driver must support CM interface.

So, this part of code mainly comes from SoftiWarp, base on it, we add some more features, such as non-blocking iw_connect implementation.
