2023-09-14cxl/mbox: Fix CEL logic for poison and security commandsIra Weiny
The following debug output was observed while testing CXL cxl_core:cxl_walk_cel:721: cxl_mock_mem cxl_mem.0: Opcode 0x4300 unsupported by driver opcode 0x4300 (Get Poison) is supported by the driver and the mock device supports it. The logic should be checking that the opcode is both not poison and not security. Fix the logic to allow poison and security commands.

2023-09-14nvme: avoid bogus CRTO valuesKeith Busch
Some devices are reporting controller ready mode support, but return 0 for CRTO. These devices require a much higher time to ready than that, so they are failing to initialize after the driver starter preferring that value over CAP.TO. The spec requires that CAP.TO match the appropritate CRTO value, or be set to 0xff if CRTO is larger than that. This means that CAP.TO can be used to validate if CRTO is reliable, and provides an appropriate fallback for setting the timeout value if not. Use whichever is larger.

2023-09-14thermal: core: Fix disabled trip point check in handle_thermal_trip()Rafael J. Wysocki
Commit bc840ea5f9a9 ("thermal: core: Do not handle trip points with invalid temperature") added a check for invalid temperature to the disabled trip point check in handle_thermal_trip(), but that check was added at a point when the trip structure has not been initialized yet. This may cause handle_thermal_trip() to skip a valid trip point in some cases, so fix it by moving the check to a suitable place, after __thermal_zone_get_trip() has been called to populate the trip structure.

As a result, active counter may never be zeroed for mddevice and it cannot be removed. Put the device which has been _get with previous md_seq_next() call.

2023-09-14dm: fix a race condition in retrieve_depsMikulas Patocka
There's a race condition in the multipath target when retrieve_deps races with multipath_message calling dm_get_device and dm_put_device. retrieve_deps walks the list of open devices without holding any lock but multipath may add or remove devices to the list while it is running. The end result may be memory corruption or use-after-free memory access. See this description of a UAF with multipath_message(): https://listman.redhat.com/archives/dm-devel/2022-October/052373.html Fix this bug by introducing a new rw semaphore "devices_lock".

This is based on alx driver commit 881d0327db37 ("net: alx: Work around the DMA RX overflow issue"). The alx and atl1c drivers had RX overflow error which was why a custom allocator was created to avoid certain addresses. The simpler workaround then created for alx driver, but not for atl1c due to lack of tester. Instead of using a custom allocator, check the allocated skb address and use skb_reserve() to move away from problematic 0x...fc0 address. Tested on AR8131 on Acer 4540.

2023-09-13scsi: lpfc: Prevent use-after-free during rmmod with mapped NVMe rportsJustin Tee
During rmmod, when dev_loss_tmo callback is called, an ndlp kref count is decremented twice. Once for SCSI transport registration and second to remove the initial node allocation kref. If there is also an NVMe transport registration, another reference count decrement is expected in lpfc_nvme_unregister_port(). Race conditions between the NVMe transport remoteport_delete and dev_loss_tmo callbacks sometimes results in premature ndlp object release resulting in use-after-free issues. Fix by not dropping the ndlp object in dev_loss_tmo callback with an outstanding NVMe transport registration. Inversely, mark the final NLP_DROPPED flag in lpfc_nvme_unregister_port when rmmod flag is set.

There is an attempt to restore the ndlp lock when exiting the if statement, but the nlp_put kref could be the final decrement causing a use-after-free memory access on a released ndlp object. Instead of trying to reacquire the ndlp lock after checking nlp_flag, just return after calling nlp_put.

Driver report the link speed on ethtool .idpf_get_link_ksettings query. Introduce soft reset function which is used by some of the ethtool callbacks such as .set_channels, .set_ringparam etc. to change the existing queue configuration. It deletes the existing queues by sending delete queues virtchnl message to the CP and calls the 'vport_stop' flow which disables the queues, vport etc. New set of queues are requested to the CP and reconfigure the queue context by calling the 'vport_open' flow.

2023-09-13idpf: add RX splitq napi poll supportAlan Brady
Add support to handle interrupts for the RX completion queue and RX buffer queue. When the interrupt fires on RX completion queue, process the RX descriptors that are received. Allocate and prepare the SKB with the RX packet info, for both data and header buffer. IDPF uses software maintained refill queues to manage buffers between RX queue producer and the buffer queue consumer. They are required in order to maintain a lockless buffer management system and are strictly software only constructs. Instead of updating the RX buffer queue tail with available buffers right after the clean routine, it posts the buffer ids to the refill queues, only to post them to the HW later. If the generic receive offload (GRO) is enabled in the capabilities and turned on by default or via ethtool, then HW performs the packet coalescing if certain criteria are met by the incoming packets and updates the RX descriptor. Similar to GRO, if generic checksum is enabled, HW computes the checksum and updates the respective fields in the descriptor. Add support to update the SKB fields with the GRO and the generic checksum received.

2023-09-13idpf: add TX splitq napi poll supportJoshua Hay
Add support to handle the interrupts for the TX completion queue and process the various completion types. In the flow scheduling mode, the driver processes primarily buffer completions as well as descriptor completions occasionally. This mode supports out of order TX completions. To do so, HW generates one buffer completion per packet. Each of those completions contains the unique tag provided during the TX encoding which is used to locate the packet either on the TX buffer ring or in a hash table. The hash table is used to track TX buffer information so the descriptor(s) for a given packet can be reused while the driver is still waiting on the buffer completion(s). Packets end up in the hash table in one of 2 ways: 1) a packet was stashed during descriptor completion cleaning, or 2) because an out of order buffer completion was processed. A descriptor completion arrives only every so often and is primarily used to guarantee the TX descriptor ring can be reused without having to wait on the individual buffer completions. E.g. a descriptor completion for N+16 guarantees HW read all of the descriptors for packets N through N+15, therefore all of the buffers for packets N through N+15 are stashed into the hash table and the descriptors can be reused for more TX packets. Similarly, a packet can be stashed in the hash table because an out an order buffer completion was processed. E.g. processing a buffer completion for packet N+3 implies that HW read all of the descriptors for packets N through N+3 and they can be reused. However, the HW did not do the DMA yet. The buffers for packets N through N+2 cannot be freed, so they are stashed in the hash table. In either case, the buffer completions will eventually be processed for all of the stashed packets, and all of the buffers will be cleaned from the hash table. In queue based scheduling mode, the driver processes primarily descriptor completions and cleans the TX ring the conventional way. Finally, the driver triggers a TX queue drain after sending the disable queues virtchnl message. When the HW completes the queue draining, it sends the driver a queue marker packet completion. The driver determines when all TX queues have been drained and proceeds with the disable flow. With this, the driver can send TX packets and clean up the resources properly.

2023-09-13idpf: configure resources for RX queuesAlan Brady
Similar to the TX, RX also supports both single and split queue models. In single queue model, the same descriptor queue is used by SW to post buffer descriptors to HW and by HW to post completed descriptors to SW. In split queue model, "RX buffer queues" are used to pass descriptor buffers from SW to HW whereas "RX queues" are used to post the descriptor completions i.e. descriptors that point to completed buffers, from HW to SW. "RX queue group" is a set of RX queues grouped together and will be serviced by a "RX buffer queue group". IDPF supports 2 buffer queues i.e. large buffer (4KB) queue and small buffer (2KB) queue per buffer queue group. HW uses large buffers for 'hardware gro' feature and also if the packet size is more than 2KB, if not 2KB buffers are used. Add all the resources required for the RX queues initialization. Allocate memory for the RX queue and RX buffer queue groups. Initialize the software maintained refill queues for buffer management algorithm.

2023-09-13idpf: configure resources for TX queuesAlan Brady
IDPF supports two queue models i.e. single queue which is a traditional queueing model as well as split queue model. In single queue model, the same descriptor queue is used by SW to post descriptors to the HW, HW to post completed descriptors to SW. In split queue model, "TX Queues" are used to pass buffers from SW to HW and "TX Completion Queues" are used to post descriptor completions from HW to SW. Device supports asymmetric ratio of TX queues to TX completion queues. Considering this, queue group mechanism is used i.e. some TX queues are grouped together which will be serviced by only one TX completion queue per TX queue group. Add all the resources required for the TX queues initialization. To start with, allocate memory for the TX queue groups, TX queues and TX completion queues. Then, allocate the descriptors for both TX and TX completion queues, and bookkeeping buffers for TX queues alone. Also, allocate queue vectors for the vport and initialize the TX queue related fields for each queue vector. Initialize the queue parameters such as q_id, q_type and tail register offset with the info received from the device control plane (CP). Once all the TX queues are configured, send config TX queue virtchnl message to the CP with all the TX queue context information.

2023-09-13virtchnl: add virtchnl version 2 opsPavan Kumar Linga
Virtchnl version 1 is an interface used by the current generation of foundational NICs to negotiate the capabilities and configure the HW resources such as queues, vectors, RSS LUT, etc between the PF and VF drivers. It is not extensible to enable new features supported in the next generation of NICs/IPUs and to negotiate descriptor types, packet types and register offsets. To overcome the limitations of the existing interface, introduce the virtchnl version 2 and add the necessary opcodes, structures, definitions, and descriptor formats. The driver also learns the data queue and other register offsets to use instead of hardcoding them. The advantage of this approach is that it gives the flexibility to modify the register offsets if needed, restrict the use of certain descriptor types and negotiate the supported packet types.

On the original devices supported by this code there were typically only one or two algorithms in a firmware and one or two DSPs so this logging only used a small number of log lines. However, for the latest devices there could be 30-40 algorithms in a firmware and 8 DSPs being loaded in parallel, so using 300+ lines of log for information that isn't particularly important to have logged.
