The FW API for PER_CHAIN_LIMIT_OFFSET_CMD is misleading. The element name is table_rev, but it shouldn't actually contain the table revision number, but whether we should use the South Korea scheme or not. Fix the driver so that we only set this value to either 0 or 1. It will only be 1 (meaning South Korea) if the ACPI WGDS table revision is 1. Signed-off-by:

We don't really have much reason to mistrust the hardware queue number, but if it gets mixed up we still don't want to access some data out of bounds, so drop such frames. Signed-off-by:

On Bz devices, the hardware checksums including the SNAP header, starting directly after the MAC header, so we don't need the extra checks and can just pass the checksum to mac80211. Signed-off-by:

For the upcoming Bz devices, we will set NETIF_F_HW_CSUM instead of NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM. However, we still need to be able to remove all the checksum bits, so add a mask for the removal, and keep the old define for the feature advertisement. Signed-off-by:

When CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, iwlwifi crashes when the opmode module cannot be loaded, due to completing the completion before using drv->dev, which can then already be freed. Fix this by removing the (fairly useless) message. Moving the completion later causes a deadlock instead, so that's not an option. Signed-off-by:

In case the fw supports OCE scan and one of the OCE feature flags are set in the scan request, set the corresponding flag in the firmware scan request. Note that new firmware that indicates OCE support does not support the probe deferral and suppression feature (which is optional). Signed-off-by:

If firmware load fails after having loaded some parts of the firmware, e.g. the IML image, then this would leak. For the host command list we'd end up running into a WARN on the next attempt to load another firmware image. Fix this by calling iwl_dealloc_ucode() on failures, and make that also clear the data so we start fresh on the next round. Signed-off-by:

Debug TLV parsing was missing size checks, so if a valid but too short TLV was encountered, it would attempt to read it. If the firmware file was arranged to be a multiple of pages long with this happening just before the end, it could crash reading out-of-bounds of a vmalloc area. Fix this by adding the relevant size check. Signed-off-by:

With more things being added, we're no longer going to duplicate the error tables from the debug TLVs nor send them at runtime. Use the debug TLVs to find the locations of the error tables. As we've never released firmware using IWL_UCODE_TLV_TCM_DEBUG_ADDRS just remove that entirely. Signed-off-by:

With the introduction of 6GHz channels the scan guard timeout should be adjusted to account for the following extreme case: - All 6GHz channels are scanned passively: 58 channels. - The scan is fragmented with the following parameters: 3 fragments, 95 TUs suspend time, 44 TUs maximal out of channel time. The above would result with scan time of more than 24 seconds. Thus, set the timeout to 30 seconds. Cc: stable@vger.kernel.org Signed-off-by:

We can detect that a FW SYSASSERT is due to missing PNVM data by checking the assertion code. When this happens, it's is useful for the user if we print the filename where the driver is looking for the data. Add the PNVM missing assertion code to the dump list and print out the name of the file we're looking for when this happens. Reported-by:

The original implementation checked the HW family, and as a result of that used different addresses for the prph registers. The old HWs addresses start with 0xa****** and the newer ones start with 0xd******. For this there are iwl_read/write_umac_prph functions that just add the diff in the address automatically (in this case 0x300000), so the code will be common for all HWs In the original implementation the address given already had the 0xd****** causing the address to become 0x10***** (after adding the offset) Change the registers to start with 0xa*****.

Contrary to what was stated before, the hardware hasn't changed the bits here yet. In any case, the new CSR is also directly (lower 16 bits) connected to UREG_DOORBELL_TO_ISR6, so if it still changes the changes would be there. Adjust the code and comments accordingly. Signed-off-by:

Tony Nguyen says: ==================== 40GbE Intel Wired LAN Driver Updates 2021-12-17 Brett Creeley says: This patch series adds support in the iavf driver for communicating and using VIRTCHNL_VF_OFFLOAD_VLAN_V2. The current VIRTCHNL_VF_OFFLOAD_VLAN is very limited and covers all 802.1Q VLAN offloads and filtering with no granularity. The new VIRTCHNL_VF_OFFLOAD_VLAN_V2 adds more granularity, flexibility, and support for 802.1ad offloads and filtering. This includes the VF negotiating which VLAN offloads/filtering it's allowed, where VLAN tags should be inserted and/or stripped into and from descriptors, and the supported VLAN protocols. ==================== Signed-off-by: -

Mat Martineau says: ==================== mptcp: Miscellaneous changes for 5.17 These are three unrelated patches that we've been testing in the MPTCP tree. Patch 1 modifies the packet scheduler that picks which TCP subflow is used for each chunk of outgoing data. The updated scheduler improves throughput on multiple-subflow connections. Patch 2 updates a selftest to verify recent TCP_ULP sockopt changes on MPTCP fallback sockets. Patch 3 cleans up some unnecessary comparisons with an 8-bit value. ==================== Link: https://lore.kernel.org/r/20211217233702.299461-1-mathew.j.martineau@linux.intel.comSigned-off-by:

entry->addr.id is u8 with a range from 0 to 255 and MAX_ADDR_ID is 255. We should drop both false expressions of (entry->addr.id > MAX_ADDR_ID). We should also remove the obsolete parentheses in the first if branch. Use U8_MAX for MAX_ADDR_ID and add a comment to show the link to mptcp_addr_info.id as suggested by Mr. Matthieu Baerts.

The kernel will crash without 'mptcp: clear 'kern' flag from fallback sockets' change. Since this doesn't slow down testing in a noticeable way, run this unconditionally. The explicit test did not catch this, because the check was done for tcp socket returned by 'socket(.. IPPROTO_TCP) rather than a tcp socket returned by accept() on a mptcp listen fd. Signed-off-by:

The MPTCP packet scheduler has sub-optimal behavior with asymmetric subflows: if the faster subflow-level cwin is closed, the packet scheduler can enqueue "too much" data on a slower subflow. When all the data on the faster subflow is acked, if the mptcp-level cwin is closed, and link utilization becomes suboptimal. The solution is implementing blest-like[1] HoL-blocking estimation, transmitting only on the subflow with the shorter estimated time to flush the queued memory. If such subflows cwin is closed, we wait even if other subflows are available. This is quite simpler than the original blest implementation, as we leverage the pacing rate provided by the TCP socket. To get a more accurate estimation for the subflow linger-time, we maintain a per-subflow weighted average of such info. Additionally drop magic numbers usage in favor of newly defined macros and use more meaningful names for status variable.
