mlx5: bpf_xdp_metadata_rx_hash add xdp rss hash type

2023-04-13T18:15:10Z

Update API for bpf_xdp_metadata_rx_hash() with arg for xdp rss hash type via mapping table. The mlx5 hardware can also identify and RSS hash IPSEC. This indicate hash includes SPI (Security Parameters Index) as part of IPSEC hash. Extend xdp core enum xdp_rss_hash_type with IPSEC hash type.

xdp: rss hash types representation

2023-04-13T18:15:10Z

The RSS hash type specifies what portion of packet data NIC hardware used when calculating RSS hash value. The RSS types are focused on Internet traffic protocols at OSI layers L3 and L4. L2 (e.g. ARP) often get hash value zero and no RSS type. For L3 focused on IPv4 vs. IPv6, and L4 primarily TCP vs UDP, but some hardware supports SCTP. Hardware RSS types are differently encoded for each hardware NIC. Most hardware represent RSS hash type as a number. Determining L3 vs L4 often requires a mapping table as there often isn't a pattern or sorting according to ISO layer. The patch introduce a XDP RSS hash type (enum xdp_rss_hash_type) that contains both BITs for the L3/L4 types, and combinations to be used by drivers for their mapping tables. The enum xdp_rss_type_bits get exposed to BPF via BTF, and it is up to the BPF-programmer to match using these defines. This proposal change the kfunc API bpf_xdp_metadata_rx_hash() adding a pointer value argument for provide the RSS hash type. Change signature for all xmo_rx_hash calls in drivers to make it compile. The RSS type implementations for each driver comes as separate patches.

rtnetlink: Restore RTM_NEW/DELLINK notification behavior

2023-04-13T03:47:58Z

The commits referenced below allows userspace to use the NLM_F_ECHO flag for RTM_NEW/DELLINK operations to receive unicast notifications for the affected link. Prior to these changes, applications may have relied on multicast notifications to learn the same information without specifying the NLM_F_ECHO flag. For such applications, the mentioned commits changed the behavior for requests not using NLM_F_ECHO. Multicast notifications are still received, but now use the portid of the requester and the sequence number of the request instead of zero values used previously. For the application, this message may be unexpected and likely handled as a response to the NLM_F_ACKed request, especially if it uses the same socket to handle requests and notifications. To fix existing applications relying on the old notification behavior, set the portid and sequence number in the notification only if the request included the NLM_F_ECHO flag. This restores the old behavior for applications not using it, but allows unicasted notifications for others.

Bluetooth: Fix printing errors if LE Connection times out

2023-04-10T17:21:33Z

This fixes errors like bellow when LE Connection times out since that is actually not a controller error: Bluetooth: hci0: Opcode 0x200d failed: -110 Bluetooth: hci0: request failed to create LE connection: err -110 Instead the code shall properly detect if -ETIMEDOUT is returned and send HCI_OP_LE_CREATE_CONN_CANCEL to give up on the connection.

2023-04-09T16:45:46Z

Pull compute express link (cxl) fixes from Dan Williams: "Several fixes for driver startup regressions that landed during the merge window as well as some older bugs. The regressions were due to a lack of testing with what the CXL specification calls Restricted CXL Host (RCH) topologies compared to the testing with Virtual Host (VH) CXL topologies. A VH topology is typical PCIe while RCH topologies map CXL endpoints as Root Complex Integrated endpoints. The impact is some driver crashes on startup. This merge window also added compatibility for range registers (the mechanism that CXL 1.1 defined for mapping memory) to treat them like HDM decoders (the mechanism that CXL 2.0 defined for mapping Host-managed Device Memory). That work collided with the new region enumeration code that was tested with CXL 2.0 setups, and fails with crashes at startup. Lastly, the DOE (Data Object Exchange) implementation for retrieving an ACPI-like data table from CXL devices is being reworked for v6.4. Several fixes fell out of that work that are suitable for v6.3. All of this has been in linux-next for a while, and all reported issues [1] have been addressed. Summary: - Fix several issues with region enumeration in RCH topologies that can trigger crashes on driver startup or shutdown. - Fix CXL DVSEC range register compatibility versus region enumeration that leads to startup crashes - Fix CDAT endiannes handling - Fix multiple buffer handling boundary conditions - Fix Data Object Exchange (DOE) workqueue usage vs CONFIG_DEBUG_OBJECTS warn splats" Link: http://lore.kernel.org/r/20230405075704.33de8121@canb.auug.org.au [1] * tag 'cxl-fixes-6.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/hdm: Extend DVSEC range register emulation for region enumeration cxl/hdm: Limit emulation to the number of range registers cxl/region: Move coherence tracking into cxl_region_attach() cxl/region: Fix region setup/teardown for RCDs cxl/port: Fix find_cxl_root() for RCDs and simplify it cxl/hdm: Skip emulation when driver manages mem_enable cxl/hdm: Fix double allocation of @cxlhdm PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y PCI/DOE: Silence WARN splat with CONFIG_DEBUG_OBJECTS=y cxl/pci: Handle excessive CDAT length cxl/pci: Handle truncated CDAT entries cxl/pci: Handle truncated CDAT header cxl/pci: Fix CDAT retrieval on big endian
