If any of the cipher schemes specified by the driver are invalid, bail out and fail the registration rather than just warning. Otherwise, we might later crash when we try to use the invalid cipher scheme, e.g. if the hdr_len is (significantly) less than the pn_offs + pn_len, we'd have an out-of-bounds access in RX validation.

After channel switch, we should consider any beacon with a CSA IE as a new switch. If the CSA IE is a leftover from before the switch that the AP forgot to remove, we'll get a CSA-to-Self. This caused issues in iwlwifi where the firmware saw a beacon with a CSA-to-Self with mode = 1 on the new channel after a switch. The firmware considered this a new switch and closed its queues. Since the beacon didn't change between before and after the switch, we wouldn't handle it (the CRC is the same) and we wouldn't let the firmware open its queues again or disconnect if the CSA IE stays for too long. Clear the CRC valid state after we switch to make sure that we handle the beacon and handle the CSA IE as required. Signed-off-by:

Some drivers, for example mt76, use the skb priority field, and expects that to be consistent with the skb queue mapping. On some frame injection code paths that was not true, and it broke frame injection. Now the skb queue mapping is set according to the skb priority value when the frame is injected. The skb priority value is also derived from the frame data for all frame types, as it was done prior to commit dbd50a85 (only allocate one queue when using iTXQs). Fixes frame injection with the mt76 driver on MT7610E chipset. Signed-off-by:

Some HW/driver can support passing ethernet rx decap frames and raw 802.11 frames for the monitor interface concurrently and via separate RX calls to mac80211. Packets going to the monitor interface(s) would be in 802.11 format and thus not have the RX_FLAG_8023 set, and 802.11 format monitoring frames should have RX_FLAG_ONLY_MONITOR set. Drivers doing such can enable the SUPPORTS_CONC_MON_RX_DECAP to allow using ethernet decap offload while a monitor interface is active, currently RX decapsulation offload gets disabled when a monitor interface is added.

In some cases (depending on the driver, but it's true e.g. for iwlwifi) we're using an internal TXQ for management packets, mostly to simplify the code and to have a place to queue them. However, it appears that in certain cases we can confuse the code and management frames are dropped, which is certainly not what we want. Short-circuit the processing of management frames. To keep the impact minimal, only put them on the frags queue and check the tid == management only for doing that and to skip the airtime fairness checks, if applicable. Signed-off-by:

The macro CN23XX_PEM_BAR1_INDEX_REG is being used to shift oct->pcie_port (a u16) left 24 places. There are two subtle issues here, first the shift gets promoted to an signed int and then sign extended to a u64. If oct->pcie_port is 0x80 or more then the upper bits get sign extended to 1. Secondly shfiting a u16 24 bits will lead to an overflow so it needs to be cast to a u64 for all the bits to not overflow. It is entirely possible that the u16 port value is never large enough for this to fail, but it is useful to fix unintended overflows such as this. Fix this by casting the port parameter to the macro to a u64 before the shift.

The first patch targets the CAN driver infrastructure, it improves the alloc_can{,fd}_skb() function to set the pointer to the CAN frame to NULL if skb allocation fails. The next patch adds missing error handling to the m_can driver's RX path (the code was introduced in -next, no need to backport). In the next patch an unused constant is removed from an enum in the c_can driver. The last 3 patches target the mcp251xfd driver. They add BQL support and try to work around a sometimes broken CRC when reading the TBC register. ==================== Signed-off-by:

Saeed Mahameed says: ==================== mlx5-updates-2021-04-06 Introduce TC sample offload Background ---------- The tc sample action allows user to sample traffic matched by tc classifier. The sampling consists of choosing packets randomly and sampling them using psample module. The tc sample parameters include group id, sampling rate and packet's truncation (to save kernel-user traffic). Sample in TC SW --------------- User must specify rate and group id for sample action, truncate is optional. tc filter add dev enp4s0f0_0 ingress protocol ip prio 1 flower \ src_mac 02:25:d0:14:01:02 dst_mac 02:25:d0:14:01:03 \ action sample rate 10 group 5 trunc 60 \ action mirred egress redirect dev enp4s0f0_1 The tc sample action kernel module 'act_sample' will call another kernel module 'psample' to send sampled packets to userspace. MLX5 sample HW offload - MLX5 driver patches -------------------------------------------- The sample action is translated to a goto flow table object destination which samples packets according to the provided sample ratio. Sampled packets are duplicated. One copy is processed by a termination table, named the sample table, which sends the packet to the eswitch manager port (that will be processed by software). The second copy is processed by the default table which executes the subsequent actions. The default table is created per <vport, chain, prio> tuple as rules with different prios and chains may overlap. For example, for the following typical flow table: +-------------------------------+ + original flow table + +-------------------------------+ + original match + +-------------------------------+ + sample action + other actions + +-------------------------------+ We translate the tc filter with sample action to the following HW model: +---------------------+ + original flow table + +---------------------+ + original match + +---------------------+ | v +------------------------------------------------+ + Flow Sampler Object + +------------------------------------------------+ + sample ratio + +------------------------------------------------+ + sample table id | default table id + +------------------------------------------------+ | | v v +-----------------------------+ +----------------------------------------+ + sample table + + default table per <vport, chain, prio> + +-----------------------------+ +----------------------------------------+ + forward to management vport + + original match + +-----------------------------+ +----------------------------------------+ + other actions + +----------------------------------------+ Flow sampler object ------------------- Hardware introduces flow sampler object to do sample. It is a new destination type. Driver needs to specify two flow table ids in it. One is sample table id. The other one is the default table id. Sample table samples the packets according to the sample rate and forward the sampled packets to eswitch manager port. Default table finishes the subsequent actions. Group id and reg_c0 ------------------- Userspace program will take different actions for sampled packets according to tc sample action group id. So hardware must pass group id to software for each sampled packets. In Paul Blakey's "Introduce connection tracking offload" patch set, reg_c0 lower 16 bits are used for miss packet chain id restore. We convert reg_c0 lower 16 bits to a common object pool, so other features can also use it. Since sample group id is 32 bits, create a 16 bits object id to map the group id and write the object id to reg_c0 lower 16 bits. reg_c0 can only be used for matching. Write reg_c0 to flow_tag, so software can get the object id via flow_tag and find group id via the common object pool. Sampler restore handle ---------------------- Use common object pool to create an object id to map sample parameters. Allocate a modify header action to write the object id to reg_c0 lower 16 bits. Create a restore rule to pass the object id to software. So software can identify sampled packets via the object id and send it to userspace. Aggregate the modify header action, restore rule and object id to a sample restore handle. Re-use identical sample restore handle for the same object id. Send sampled packets to userspace --------------------------------- The destination for sampled packets is eswitch manager port, so representors can receive sampled packets together with the group id. Driver will send sampled packets and group id to userspace via psample. ==================== Signed-off-by: -
