2023-03-15wifi: iwlwifi: mvm: Refactor MAC_CONTEXT_CMD sending flowMiri Korenblit
Refactor MAC_CONTEXT_CMD sending flow: 1. As the new MLD API is introduced, there are some common fields in both the old and new APIs. The MAC_CONTEXT_CMD of the non-MLD API has common fields with the link and mac commands of the new MLD API. Put this common parts in functions so it can be used later by the new MLD API. 2. Use iwl_mvm_mac_ctxt_send_cmd when removing a mac instead of implementing the same functionality once again. 3. Change the debug print when sending the command to be more specific, so it will be easy to distinguish later if the old or new mac command was sent.

The HE capability which indicates whether the NIC is ack-enabled or not is the same for all bands. No need to take it from the specific band which is currently in use. Take it from the low band - this simplifies the code and doesn't require a phy_ctxt.

2023-03-15wifi: iwlwifi: mvm: avoid sta lookup in queue allocJohannes Berg
In FW restart scenarios, we allocate the queues from the iwl_mvm_realloc_queues_after_restart() function, but that is called before we insert the station ID into our map (mvm->fw_id_to_mac_id). However, in all cases where we're actually allocating a queue for a "real" (not bcast, aux, ...) station we have the sta pointer already, so just pass it along to use it instead of looking it up. This fixes an issue where after restart we only allocated a queue of size 16 (due to the ordering issue described above), and thus never got good throughput again since no aggregates could be formed on transmit.

2023-03-13wifi: ipw2x00: convert ipw_fw_error->elem to flexible array[]Jacob Keller
The ipw_fw_error structure contains a payload[] flexible array as well as two pointers to this array area, ->elem, and ->log. The total size of the allocated structure is computed without use of the <linux/overflow.h> macros. There's no reason to keep both a payload[] and an extra pointer to both the elem and log members. Convert the elem pointer member into the flexible array member, removing payload. Fix the allocation of the ipw_fw_error structure to use size_add(), struct_size(), and array_size() to compute the allocation. This ensures that any overflow saturates at SIZE_MAX rather than overflowing and potentially allowing an undersized allocation. Before the structure change, the layout of ipw_fw_error was: struct ipw_fw_error { long unsigned int jiffies; /* 0 8 */ u32 status; /* 8 4 */ u32 config; /* 12 4 */ u32 elem_len; /* 16 4 */ u32 log_len; /* 20 4 */ struct ipw_error_elem * elem; /* 24 8 */ struct ipw_event * log; /* 32 8 */ u8 payload[]; /* 40 0 */ /* size: 40, cachelines: 1, members: 8 */ /* last cacheline: 40 bytes */ }; After this change, the layout is now: struct ipw_fw_error { long unsigned int jiffies; /* 0 8 */ u32 status; /* 8 4 */ u32 config; /* 12 4 */ u32 elem_len; /* 16 4 */ u32 log_len; /* 20 4 */ struct ipw_event * log; /* 24 8 */ struct ipw_error_elem elem[]; /* 32 0 */ /* size: 32, cachelines: 1, members: 7 */ /* last cacheline: 32 bytes */ }; This saves a total of 8 bytes for every ipw_fw_error allocation, and removes the risk of a potential overflow on the allocation.

2023-03-07wifi: iwlwifi: mvm: fix EOF bit reportingJohannes Berg
In monitor mode, we try to report the EOF bit on the first MPDU of an A-MPDU (hardware duplicates this bit over all MPDUs, so it's only trustable on the first). However, due to reshuffling in an ealier commit, the toggle_bit != mvm->ampdu_toggle logic can no longer work since mvm->ampdu_toggle is now set before this code runs. Fix this by tracking the first_subframe status in the phy data struct and using that instead of checking.

For the old TX API we need the tfd_queue_msk, but for the new TX API we don't need it here because we add it to the station later. However, for the new API mvm->snif_queue is set to IWL_MVM_INVALID_QUEUE == 0xffff, so the BIT() here is undefined behaviour.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core: - Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use. - Introduce sysctl to set default RPS configuration for new netdevs. - Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols: - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF: - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter: - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API: - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.
