2021-12-22selftests: forwarding: Add VxLAN tests with a VLAN-unaware bridge for IPv6Amit Cohen
Add tests similar to vxlan_bridge_1d.sh and vxlan_bridge_1d_port_8472.sh. The tests set up a topology with three VxLAN endpoints: one "local", possibly offloaded, and two "remote", formed using veth pairs and likely purely software bridges. The "local" endpoint is connected to host systems by a VLAN-unaware bridge. Since VxLAN tunnels must be unique per namespace, each of the "remote" endpoints is in its own namespace. H3 forms the bridge between the three domains. Send IPv4 packets and IPv6 packets with IPv6 underlay. Use `TC_FLAG`, which is defined in `forwarding.config` file, for TC checks. `TC_FLAG` allows testing that on HW datapath, the traffic actually goes through HW.

2021-12-22selftests: lib.sh: Add PING_COUNT to allow sending configurable amount of ↵Amit Cohen
packets Currently `ping_do()` and `ping6_do()` send 10 packets. There are cases that it is not possible to catch only the interesting packets using tc rule, so then, it is possible to send many packets and verify that at least this amount of packets hit the rule. Add `PING_COUNT` variable, which is set to 10 by default, to allow tests sending more than 10 packets using the existing ping API.

2021-12-22mlxsw: spectrum_flower: Make vlan_id limitation more specificAmit Cohen
Spectrum ASICs do not support matching of VLAN ID at egress. Currently, mlxsw driver forbids matching of all VLAN related fields at egress, which is too strict check. For example, the following filter is not supported by the driver: $ tc filter add dev swpX egress protocol 802.1q pref 1 handle 101 flower vlan_ethtype ipv4 src_ip .. dst_ip .. skip_sw action pass Error: mlxsw_spectrum: vlan_id key is not supported on egress. We have an error talking to the kernel The filter above does not match on VLAN ID, but is bounced anyway. Make the check more specific, forbid only matching of 'vlan_id' at egress.

2021-12-23netfilter: nat: force port remap to prevent shadowing well-known portsFlorian Westphal
If destination port is above 32k and source port below 16k assume this might cause 'port shadowing' where a 'new' inbound connection matches an existing one, e.g. inbound X:41234 -> Y:53 matches existing conntrack entry Z:53 -> X:4123, where Z got natted to X. In this case, new packet is natted to Z:53 which is likely unwanted. We avoid the rewrite for connections that originate from local host: port-shadowing is only possible with forwarded connections.

2021-12-22codel: remove unnecessary pkt_sched.h includeJakub Kicinski
Commit d068ca2ae2e6 ("codel: split into multiple files") moved all Qdisc-related code to codel_qdisc.h, move the include of pkt_sched.h as well. This is similar to the previous commit, although we don't care as much about incremental builds after pkt_sched.h was touched itself it is included by net/sch_generic.h which is modified ~20 times a year. This decreases the incremental build size after touching pkt_sched.h from 1592 to 617 objects. Fix unmasked missing includes in WiFi drivers.

2021-12-22codel: remove unnecessary sock.h includeJakub Kicinski
Since sock.h is modified relatively often (60 times in the last 12 months) it seems worthwhile to decrease the incremental build work. CoDel's header includes net/inet_ecn.h which in turn includes net/sock.h. codel.h is itself included by mac80211 which is included by much of the WiFi stack and drivers. Removing the net/inet_ecn.h include from CoDel breaks the dependecy between WiFi and sock.h. Commit d068ca2ae2e6 ("codel: split into multiple files") moved all the code which actually needs ECN helpers out to net/codel_impl.h, the include can be moved there as well. This decreases the incremental build size after touching sock.h from 4999 objects to 4051 objects. Fix unmasked missing includes in WiFi drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== 100GbE Intel Wired LAN Driver Updates 2021-12-21 This series contains updates to ice driver only. Karol modifies the reset flow to correct issues with PTP reset. Jake extends PTP support for E822 based devices. This includes a few cleanup patches, that fix some minor issues. In addition, there are some slight refactors to ease the addition of E822 support, followed by adding the new hardware implementation ice_ptp_hw.c. There are a few major differences with E822 support compared to E810 support: *) The E822 device has a Clock Generation Unit which must be initialized in order to generate proper clock frequencies on the output that drives the PTP hardware clock registers *) The E822 PHY is a bit different and requires a more complex initialization procedure which must be rerun any time the link configuration changes. *) The E822 devices support enhanced timestamp calibration by making use of a process called Vernier offset measurement. This allows the hardware to measure phase offset related to the PHY clocks for Serdes and FEC, reducing the inaccuracy of the timestamp relative to the actual packet transmission and receipt. Making use of this requires data gathered from the first transmitted and received packets, and waiting for the PHY to complete the calibration measurements. This is done as part of a new kthread, ov_work. Note that to avoid delay in enabling timestamps, we start the PHY in 'bypass' mode which allows timestamps to be captured without the Vernier calibration measurement. Once the first packets have been sent and received, we then complete the calibration setup and exit bypass mode and begin using the more precise timestamps. According to the datasheet, timestamps without calibration data can be incorrect relative to actual receipt or transmission by up to 1 clock cycle (~1.25 nanoseconds), while calibrated timestamps should be correct to within 1/8th of a clock cycle (~0.15 nanoseconds). *) E822 devices support crosstimestamping via PCIe PTM, which we enable when available on the platform. There is a fair amount of logic required to perform PHY and CGU initialization, which is the vast majority of the new code, but it is fairly self contained within ice_ptp_hw.c, with the exception of monitoring for offset validity being handled by a kthread. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: support crosstimestamping on E822 devices if supported ice: exit bypass mode once hardware finishes timestamp calibration ice: ensure the hardware Clock Generation Unit is configured ice: implement basic E822 PTP support ice: convert clk_freq capability into time_ref ice: introduce ice_ptp_init_phc function ice: use 'int err' instead of 'int status' in ice_ptp_hw.c ice: PTP: move setting of tstamp_config ice: introduce ice_base_incval function ice: Fix E810 PTP reset flow ==================== Link: https://lore.kernel.org/r/20211221174845.3063640-1-anthony.l.nguyen@intel.com Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The ALC256 codec needs a different quirk for the headset microphone working and and edditional quirk for sound working after suspend and resume. When waking up from s3 suspend the Coef 0x10 is set to 0x0220 instead of 0x0020 on the ALC256 codec. Setting the value manually makes the sound work again. This patch does this automatically.

The user_pversion was uninitialized for the user space file structure in the open function, because the file private structure use kmalloc for the allocation. The kernel ALSA sequencer code clears the file structure, so no additional fixes are required.

2021-12-22ALSA: hda: intel-sdw-acpi: harden detection of controllerLibin Yang
The existing code currently sets a pointer to an ACPI handle before checking that it's actually a SoundWire controller. This can lead to issues where the graph walk continues and eventually fails, but the pointer was set already. This patch changes the logic so that the information provided to the caller is set when a controller is found.

2021-12-22ALSA: hda/hdmi: Disable silent stream on GLKVille Syrjälä
The silent stream stuff recurses back into i915 audio component .get_power() from the .pin_eld_notify() hook. On GLK this will deadlock as i915 may already be holding the relevant modeset locks during .pin_eld_notify() and the GLK audio vs. CDCLK workaround will try to grab the same locks from .get_power(). Until someone comes up with a better fix just disable the silent stream support on GLK.

2021-12-22wilc1000: Add reset/enable GPIO support to SPI driverDavid Mosberger-Tang
For the SDIO driver, the RESET/ENABLE pins of WILC1000 are controlled through the SDIO power sequence driver. This commit adds analogous support for the SPI driver. Specifically, during initialization, the chip will be ENABLEd and taken out of RESET and during deinitialization, the chip will be placed back into RESET and disabled (both to reduce power consumption and to ensure the WiFi radio is off). Both RESET and ENABLE GPIOs are optional. However, if the ENABLE GPIO is specified, then the RESET GPIO should normally also be specified as otherwise there is no way to ensure proper timing of the ENABLE/RESET sequence.

2021-12-22ath11k: Fix unexpected return buffer manager error for QCA6390Baochen Qiang
We are seeing below error on QCA6390: ... [70211.671189] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22 [70212.696154] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22 [70213.092941] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22 ... The reason is that, with commit 734223d78428 ("ath11k: change return buffer manager for QCA6390"), ath11k expects the return buffer manager (RBM) field of descriptor configured as HAL_RX_BUF_RBM_SW1_BM when parsing error frames from WBM2SW3_RELEASE ring. This is a wrong change cause the RBM field is set as HAL_RX_BUF_RBM_SW3_BM. The same issue also applies to REO2TCL ring though we have not got any error reported. Fix it by changing RBM from HAL_RX_BUF_RBM_SW1_BM to HAL_RX_BUF_RBM_SW3_BM for these two rings.
