2022-01-07mptcp: keep snd_una updated for fallback socketPaolo Abeni
After shutdown, for fallback MPTCP sockets, we always have write_seq == snd_una+1 The above will foul OUTQ ioctl(). Keep snd_una in sync with write_seq even after shutdown.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2022-01-06 1) Expose FEC per lane block counters via ethtool 2) Trivial fixes/updates/cleanup to mlx5e netdev driver 3) Fix htmldoc build warning 4) Spread mlx5 SFs (sub-functions) to all available CPU cores: Commits 1..5 Shay Drory Says: ================ Before this patchset, mlx5 subfunction shared the same IRQs (MSI-X) with their peers subfunctions, causing them to use same CPU cores. In large scale, this is very undesirable, SFs use small number of cpu cores and all of them will be packed on the same CPU cores, not utilizing all CPU cores in the system. In this patchset we want to achieve two things. a) Spread IRQs used by SFs to all cpu cores b) Pack less SFs in the same IRQ, will result in multiple IRQs per core. In this patchset, we spread SFs over all online cpus available to mlx5 irqs in Round-Robin manner. e.g.: Whenever a SF is created, pick the next CPU core with least number of SF IRQs bound to it, SFs will share IRQs on the same core until a certain limit, when such limit is reached, we request a new IRQ and add it to that CPU core IRQ pool, when out of IRQs, pick any IRQ with least number of SF users. This enhancement is done in order to achieve a better distribution of the SFs over all the available CPUs, which reduces application latency, as shown bellow.

2022-01-07Bluetooth: btintel: Fix broken LED quirk for legacy ROM devicesTedd Ho-Jeong An
This patch fixes the broken LED quirk for Intel legacy ROM devices. To fix the LED issue that doesn't turn off immediately, the host sends the SW RFKILL command while shutting down the interface and it puts the devices in SW RFKILL state. Once the device is in SW RFKILL state, it can only accept HCI_Reset to exit from the SW RFKILL state. This patch checks the quirk for broken LED and sends the HCI_Reset before sending the HCI_Intel_Read_Version command.

Ido Schimmel says: ==================== mlxsw: Add Spectrum-4 support This patchset adds Spectrum-4 support in mlxsw. It builds on top of a previous patchset merged in commit 10184da91666 ("Merge branch 'mlxsw-Spectrum-4-prep'") and makes two additional changes before adding Spectrum-4 support. Patchset overview: Patches #1-#2 add a few Spectrum-4 specific variants of existing ACL keys. The new variants are needed because the size of certain key elements (e.g., local port) was increased in Spectrum-4. Patches #3-#6 are preparations. Patch #7 implements the Spectrum-4 variant of the Bloom filter hash function. The Bloom filter is used to optimize ACL lookups by potentially skipping certain lookups if they are guaranteed not to match. See additional info in merge commit ae6750e0a5ef ("Merge branch 'mlxsw-spectrum_acl-Add-Bloom-filter-support'").

2022-01-06mlxsw: spectrum_acl_bloom_filter: Add support for Spectrum-4 calculationAmit Cohen
Spectrum-4 will calculate hash function for bloom filter differently from the existing ASICs. First, two hash functions will be used to calculate 16 bits result. The final result will be combination of the two results - 6 bits which are result of CRC-6 will be used as MSB and 10 bits which are result of CRC-10 will be used as LSB. Second, while in Spectrum{2,3}, there is a padding in each chunk, so the chunks use a sequence of whole bytes, in Spectrum-4 there is no padding, so each chunk use 20 bytes minus 2 bits, so it is necessary to align the chunks to be without holes. Add dedicated 'mlxsw_sp_acl_bf_ops' for Spectrum-4 and add the required tables for CRC calculations. All the details are documented as part of the code for future use.

2022-01-06mlxsw: Introduce flex key elements for Spectrum-4Amit Cohen
Spectrum-4 ASIC will support more virtual routers and local ports compared to the existing ASICs. Therefore, the virtual router and local port ACL key elements need to be increased. Introduce new key elements for Spectrum-4 to be aligned with the elements used already for other Spectrum ASICs. The key blocks layout is the same for Spectrum-4, so use the existing code for encode_block() and clear_block(), just create separate blocks. Note that size of `VIRT_ROUTER_MSB` is 4 bits in Spectrum-4, therefore declare it using `MLXSW_AFK_ELEMENT_INST_U32()`, in order to be able to set `.avoid_size_check` to true. Otherwise, `mlxsw_afk_blocks_check()` will fail and warn.

2022-01-06net/mlx5e: Unblock setting vid 0 for VF in case PF isn't eswitch managerMaor Dickman
When using libvirt to passthrough VF to VM it will always set the VF vlan to 0 even if user didn’t request it, this will cause libvirt to fail to boot in case the PF isn't eswitch owner. Example of such case is the DPU host PF which isn't eswitch manager, so any attempt to passthrough VF of it using libvirt will fail. Fix it by not returning error in case set VF vlan is called with vid 0.

2022-01-06net/mlx5: Update log_max_qp value to FW max capabilityMaher Sanalla
log_max_qp in driver's default profile #2 was set to 18, but FW actually supports 17 at the most - a situation that led to the concerning print when the driver is loaded: "log_max_qp value in current profile is 18, changing to HCA capabaility limit (17)" The expected behavior from mlx5_profile #2 is to match the maximum FW capability in regards to log_max_qp. Thus, log_max_qp in profile #2 is initialized to a defined static value (0xff) - which basically means that when loading this profile, log_max_qp value will be what the currently installed FW supports at most.

2022-01-06selftests/bpf: Don't rely on preserving volatile in PT_REGS macros in loop3Andrii Nakryiko
PT_REGS*() macro on some architectures force-cast struct pt_regs to other types (user_pt_regs, etc) and might drop volatile modifiers, if any. Volatile isn't really required as pt_regs value isn't supposed to change during the BPF program run, so this is correct behavior. But progs/loop3.c relies on that volatile modifier to ensure that loop is preserved. Fix loop3.c by declaring i and sum variables as volatile instead. It preserves the loop and makes the test pass on all architectures (including s390x which is currently broken).

2022-01-06ice: improve switchdev's slow-pathWojciech Drewek
In current switchdev implementation, every VF PR is assigned to individual ring on switchdev ctrl VSI. For slow-path traffic, there is a mapping VF->ring done in software based on src_vsi value (by calling ice_eswitch_get_target_netdev function). With this change, HW solution is introduced which is more efficient. For each VF, src MAC (VF's MAC) filter will be created, which forwards packets to the corresponding switchdev ctrl VSI queue based on src MAC address. This filter has to be removed and then replayed in case of resetting one VF. Keep information about this rule in repr->mac_rule, thanks to that we know which rule has to be removed and replayed for a given VF. In case of CORE/GLOBAL all rules are removed automatically. We have to take care of readding them. This is done by ice_replay_vsi_adv_rule. When driver leaves switchdev mode, remove all advanced rules from switchdev ctrl VSI. This is done by ice_rem_adv_rule_for_vsi. Flag repr->rule_added is needed because in some cases reset might be triggered before VF sends request to add MAC.
