The switch has internal PTP hardware clocks. Add support for it. There are three clocks: * Synchronized * Syntonized * Free running Currently the synchronized clock is exported to user space which is a good default for the beginning. The free running clock might be exported later e.g. for implementing 802.1AS-2011/2020 Time Aware Bridges (TAB). The switch also supports cross time stamping for that purpose. The implementation adds support setting/getting the time as well as offset and frequency adjustments. However, the clock only holds a partial timeofday timestamp. This is why we track the seconds completely in software (see overflow work and last_ts). Furthermore, add the PTP multicast addresses into the FDB to forward that packages only to the CPU port where they are processed by a PTP program. Signed-off-by:

Add a basic DSA driver for Hirschmann Hellcreek switches. Those switches are implementing features needed for Time Sensitive Networking (TSN) such as support for the Time Precision Protocol and various shapers like the Time Aware Shaper. This driver includes basic support for networking: * VLAN handling * FDB handling * Port statistics * STP * Phylink Signed-off-by:

Some switches rely on unique pvids to ensure port separation in standalone mode, because they don't have a port forwarding matrix configurable in hardware. So, setups like a group of 2 uppers with the same VLAN, swp0.100 and swp1.100, will cause traffic tagged with VLAN 100 to be autonomously forwarded between these switch ports, in spite of there being no bridge between swp0 and swp1. These drivers need to prevent this from happening. They need to have VLAN filtering enabled in standalone mode (so they'll drop frames tagged with unknown VLANs) and they can only accept an 8021q upper on a port as long as it isn't installed on any other port too. So give them the chance to veto bad user requests. Signed-off-by:

The Hirschmann Hellcreek TSN switches have a special tagging protocol for frames exchanged between the CPU port and the master interface. The format is a one byte trailer indicating the destination or origin port. It's quite similar to the Micrel KSZ tagging. That's why the implementation is based on that code. Signed-off-by:

Allow user to request action terse dump with new flag value TCA_FLAG_TERSE_DUMP. Only output essential action info in terse dump (kind, stats, index and cookie, if set by the user when creating the action). This is different from filter terse dump where index is excluded (filter can be identified by its own handle). Move tcf_action_dump_terse() function to the beginning of source file in order to call it from tcf_dump_walker(). Signed-off-by:

This patch added the test case for retransmitting ADD_ADDR when timeout occurs. It set NS1's add_addr_timeout to 1 second, and drop NS2's ADD_ADDR echo packets. Here we need to slow down the transfer process of all data to let the ADD_ADDR suboptions can be retransmitted three times. So we added a new parameter "speed" for do_transfer, it can be set with fast or slow. We also added three new optional parameters for run_tests, and dropped run_remove_tests function. Since we added the netfilter rules in this test case, we need to update the "config" file. Suggested-by:

When the TCP stack splits a packet on the write queue, the tail half currently lose the associated skb extensions, and will not carry the DSM on the wire. The above does not cause functional problems and is allowed by the RFC, but interact badly with GRO and RX coalescing, as possible candidates for aggregation will carry different TCP options. This change tries to improve the MPTCP behavior, propagating the skb extensions on split. Additionally, we must prevent the MPTCP stack from updating the mapping after the split occur: that will both violate the RFC and fool the reader. Signed-off-by:

In addition to tcp autotuning during read, it may also increase the receive buffer in tcp_clamp_window(). In this case, mptcp should adjust its receive buffer size as well so it can move all pending skbs from the subflow socket to the mptcp socket. At this time, TCP can have more skbs ready for processing than what the mptcp receive buffer size allows. In the mptcp case, the receive window announced is based on the free space of the mptcp parent socket instead of the individual subflows. Following the subflow allows mptcp to grow its receive buffer. This is especially noticeable for loopback traffic where two skbs are enough to fill the initial receive window. In mptcp_data_ready() we do not hold the mptcp socket lock, so modifying mptcp_sk->sk_rcvbuf is racy. Do it when moving skbs from subflow to mptcp socket, both sockets are locked in this case.

The ADIN1300/ADIN1200 support cable diagnostics using TDR. The cable fault detection is automatically run on all four pairs looking at all combinations of pair faults by first putting the PHY in standby (clear the LINK_EN bit, PHY_CTRL_3 register, Address 0x0017) and then enabling the diagnostic clock (set the DIAG_CLK_EN bit, PHY_CTRL_1 register, Address 0x0012). Cable diagnostics can then be run (set the CDIAG_RUN bit in the CDIAG_RUN register, Address 0xBA1B). The results are reported for each pair in the cable diagnostics results registers, CDIAG_DTLD_RSLTS_0, CDIAG_DTLD_RSLTS_1, CDIAG_DTLD_RSLTS_2, and CDIAG_DTLD_RSLTS_3, Address 0xBA1D to Address 0xBA20). The distance to the first fault for each pair is reported in the cable fault distance registers, CDIAG_FLT_DIST_0, CDIAG_FLT_DIST_1, CDIAG_FLT_DIST_2, and CDIAG_FLT_DIST_3, Address 0xBA21 to Address 0xBA24). This change implements support for this using phylib's cable-test support. Reviewed-by:

When the PHY powers up, the diagnostics clock isn't enabled (bit 2 in register PHY_CTRL_1 (0x0012)). Also, the PHY is not in standby mode, so bit 13 in PHY_CTRL_3 (0x0017) is always set at power up. The standby mode and the diagnostics clock are both meant to be for the cable diagnostics feature of the PHY (in phylib this would be equivalent to the cable-test support), and for the frame-generator feature of the PHY. In standby mode, the PHY doesn't negotiate links or manage links. To use the cable diagnostics/test (or frame-generator), the PHY must be first set in standby mode, so that the link operation doesn't interfere. Then, the diagnostics clock must be enabled. For the cable-test feature, when the operation finishes, the PHY goes into PHY_UP state, and the config_aneg hook is called. For the ADIN PHY, we need to make sure that during autonegotiation configuration/setup the PHY is removed from standby mode and the diagnostics clock is disabled, so that normal operation is resumed. This change does that by moving the set of the ADIN1300_LINKING_EN bit (2) in the config_aneg (to disable standby mode). Previously, this was set in the downshift setup, because the downshift retry value and the ADIN1300_LINKING_EN are in the same register. And the ADIN1300_DIAG_CLK_EN bit (13) is cleared, to disable the diagnostics clock. Reviewed-by:

Nikolay Aleksandrov says: ==================== selftests: net: bridge: add tests for MLDv2 This is the second selftests patch-set for the new multicast functionality which adds tests for the bridge's MLDv2 support. The tests use full precooked packets which are sent via mausezahn and the resulting state after each test is checked for proper X,Y sets, (*,G) source list, source list entry timers, (S,G) existence and flags, packet forwarding and blocking, exclude group expiration and (*,G) auto-add. The first 3 patches factor out common functions which are used by IGMPv3 tests in lib.sh and add support for IPv6 test UDP packet, then patch 4 adds the first test with the initial MLDv2 setup. The following new tests are added: - base case: MLDv2 report ff02::cc is_include - include -> allow report - include -> is_include report - include -> is_exclude report - include -> to_exclude report - exclude -> allow report - exclude -> is_include report - exclude -> is_exclude report - exclude -> to_exclude report - include -> block report - exclude -> block report - exclude timeout (move to include + entry deletion) - S,G port entry automatic add to a *,G,exclude port The variable names and set notation are the same as per RFC 3810, for more information check RFC 3810 sections 2.3 and 7. ==================== Link: https://lore.kernel.org/r/20201103172412.1044840-1-razor@blackwall.orgSigned-off-by:

Alex Elder says: ==================== net: ipa: tell GSI the IPA version The GSI code that supports IPA avoids having knowledge about the IPA layer it serves. One result of this is that Boolean flags are used during GSI initialization to convey that certain hardware version-dependent special behaviors should be used. A given version of IPA hardware uses a fixed/well-defined version of GSI, so the IPA version really implies the GSI version. If given only the IPA version, the GSI code supporting IPA can use it to implement certain special behaviors required for IPA *or* GSI. This avoids the need to pass and maintain numerous Boolean flags. ==================== Link: https://lore.kernel.org/r/20201102175400.6282-1-elder@linaro.orgSigned-off-by:

We enable a channel doorbell engine only for IPA v3.5.1, and that is now handled directly by gsi_channel_program(). When initially setting up a channel, we want that doorbell engine enabled, and we can request that independent of the IPA version. Doing that makes the "legacy" argument to gsi_channel_setup_one() unnecessary. And with that gone we can get rid of the "legacy" argument to gsi_channel_setup(), and gsi_setup() as well.

Use the IPA version in gsi_channel_program() to determine whether we should enable the GSI doorbell engine when requested. This way, callers only say whether or not it should be enabled if needed, regardless of hardware version. Rename the "legacy" argument to gsi_channel_reset(), and have it indicate whether the doorbell engine should be enabled when reprogramming following the reset. Change all callers of gsi_channel_reset() to indicate whether to enable the doorbell engine after reset, independent of hardware version. Rework a little logic in ipa_endpoint_reset() to get rid of the "legacy" variable previously passed to gsi_channel_reset(). Signed-off-by:

A quirk of IPA v3.5.1 requires a channel reset on an RX channel to be performed twice. Use the IPA version in gsi_channel_reset() rather than the passed-in legacy flag to determine that. This is actually a bug fix, because this double reset is supposed to occur independent of whether we're enabling the doorbell engine. Now they will be independent. Signed-off-by:
