As explained in Documentation/networking/dsa/sja1105.rst, this switch has a static config held in the driver's memory and re-uploaded from time to time into the device (after any major change). The format of this static config is in fact described in UM10944.pdf and it contains all the switch's settings (it also contains device ID, table CRCs, etc, just like in the manual). So it is a useful and universal devlink region to expose to user space, for debugging purposes. Signed-off-by:

Jesse Brandeburg says: ==================== make drivers/net/ethernet W=1 clean The Goal: move to W=1 being default for drivers/net/ethernet, and then use automation to catch more code issues (warnings) being introduced. The status: Getting much closer but not quite done for all architectures. After applying the patches below, the drivers/net/ethernet directory can be built as modules with W=1 with no warnings (so far on x64_64 arch only!). As Jakub pointed out, there is much more work to do to clean up C=1, but that will be another series of changes. This series removes 1,247 warnings and hopefully allows the ethernet directory to move forward from here without more warnings being added. There is only one objtool warning now. This version drops one of the Intel patches, as I couldn't reproduce the original issue to document the warning. Some of these patches are already sent and tested on Intel Wired Lan, but the rest of the series titled drivers/net/ethernet affects other drivers. The changes are all pretty straightforward. ==================== Signed-off-by:

As part of the W=1 cleanups for ethernet, a million [*] driver comments had to be cleaned up to get the W=1 compilation to succeed. This change finally makes the drivers/net/ethernet tree compile with W=1 set on the command line. NOTE: The kernel uses kdoc style (see Documentation/process/kernel-doc.rst) when documenting code, not doxygen or other styles. After this patch the x86_64 build has no warnings from W=1, however scripts/kernel-doc says there are 1545 more warnings in source files, that I need to develop a script to fix in a followup patch. The errors fixed here are all kdoc of a few classes, with a few outliers: In file included from drivers/net/ethernet/qlogic/netxen/netxen_nic_hw.c:10: drivers/net/ethernet/qlogic/netxen/netxen_nic.h:1193:18: warning: ‘FW_DUMP_LEVELS’ defined but not used [-Wunused-const-variable=] 1193 | static const u32 FW_DUMP_LEVELS[] = { 0x3, 0x7, 0xf, 0x1f, 0x3f, 0x7f, 0xff }; | ^~~~~~~~~~~~~~ ... repeats 4 times... drivers/net/ethernet/sun/cassini.c:2084:24: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] 2084 | RX_USED_ADD(page, i); drivers/net/ethernet/natsemi/ns83820.c: In function ‘phy_intr’: drivers/net/ethernet/natsemi/ns83820.c:603:6: warning: variable ‘tbisr’ set but not used [-Wunused-but-set-variable] 603 | u32 tbisr, tanar, tanlpar; | ^~~~~ drivers/net/ethernet/natsemi/ns83820.c: In function ‘ns83820_get_link_ksettings’: drivers/net/ethernet/natsemi/ns83820.c:1207:11: warning: variable ‘tanar’ set but not used [-Wunused-but-set-variable] 1207 | u32 cfg, tanar, tbicr; | ^~~~~ drivers/net/ethernet/packetengines/yellowfin.c:1063:18: warning: variable ‘yf_size’ set but not used [-Wunused-but-set-variable] 1063 | int data_size, yf_size; | ^~~~~~~ Normal kdoc fixes: warning: Function parameter or member 'x' not described in 'y' warning: Excess function parameter 'x' description in 'y' warning: Cannot understand <string> on line <NNN> - I thought it was a doc line [*] - ok it wasn't quite a million, but it felt like it.

While fixing the W=1 builds, this warning came up because the developers used a very tricky way to get structures initialized to a non-zero value, but this causes GCC to warn about an override. In this case the override was intentional, so just disable the warning for this code with a kernel macro that results in disabling the warning for compiles on GCC versions after 8. It is not appropriate to change the struct to initialize all the values as it will just add a lot more code for no value. The code is completely correct as is, we just want to acknowledge that this code could generate a warning and we're ok with that. NOTE: the __diag_ignore macro currently only accepts a second argument of 8 (version 80000), it's either use this one or open code the pragma. Fixed Warnings example (all the same): drivers/net/ethernet/renesas/sh_eth.c:51:12: warning: initialized field overwritten [-Woverride-init] drivers/net/ethernet/renesas/sh_eth.c:52:12: warning: initialized field overwritten [-Woverride-init] drivers/net/ethernet/renesas/sh_eth.c:53:13: warning: initialized field overwritten [-Woverride-init] + 256 more...

Remove variables that were storing a return value from a register read or other read, where the return value wasn't used. Those conversions to remove the lvalue of the assignment should be safe because the readl memory mapped reads are marked volatile and should not be optimized out without an lvalue (I suspect a very long time ago this wasn't guaranteed as it is today).

There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers.

While we should always make sure that we specify a valid VLAN protocol to vlan_proto_idx(), killing the machine when an invalid value is specified is too harsh and not helpful for debugging. All callers are capable of dealing with an error returned by vlan_proto_idx() so check the index value and propagate it accordingly. Signed-off-by:

The 200G device has a new device id 0xA228, so adds this device id to pci table, then the driver can probe it. As speed_ability queried from firmware has only 8 bits and already be used up, so firmware adds extra speed_ability_ext to indicate more speed abilities to support 200G and driver needs to parse it.

Geliang Tang says: ==================== mptcp: RM_ADDR/ADD_ADDR enhancements This series include two enhancements for the MPTCP path management, namely RM_ADDR support and ADD_ADDR echo support, as specified by RFC sections 3.4.1 and 3.4.2. 1 RM_ADDR support include 9 patches (1-3 and 8-13): Patch 1 is the helper for patch 2, these two patches add the RM_ADDR outgoing functions, which are derived from ADD_ADDR's corresponding functions. Patch 3 adds the RM_ADDR incoming logic, when RM_ADDR suboption is received, close the subflow matching the rm_id, and update PM counter. Patch 8 is the main remove routine. When the PM netlink removes an address, we traverse all the existing msk sockets to find the relevant sockets. Then trigger the RM_ADDR signal and remove the subflow which using this local address, this subflow removing functions has been implemented in patch 9. Finally, patches 10-13 are the self-tests for RM_ADDR. 2 ADD_ADDR echo support include 7 patches (4-7 and 14-16). Patch 4 adds the ADD_ADDR echo logic, when the ADD_ADDR suboption has been received, send out the same ADD_ADDR suboption with echo-flag, and no HMAC included. Patches 5 and 6 are the self-tests for ADD_ADDR echo. Patch 7 is a little cleaning up. Patch 14 and 15 are the helpers for patch 16. These three patches add the ADD_ADDR retransmition when no ADD_ADDR echo is received. ==================== Signed-off-by:

This patch implemented the retransmition of ADD_ADDR when no ADD_ADDR echo is received. It added a timer with the announced address. When timeout occurs, ADD_ADDR will be retransmitted. Suggested-by:

This patch added the remove addr and subflow test cases and two new functions. The first function run_remove_tests calls do_transfer with two new arguments, rm_nr_ns1 and rm_nr_ns2, for the numbers of addresses should be removed during the transfer process in namespace 1 and namespace 2. If both these two arguments are 0, we do the join test cases with "mptcp_connect -j" command. Otherwise, do the remove test cases with "mptcp_connect -r" command. The second function chk_rm_nr checks the RM_ADDR related mibs's counters. The output of the test cases looks like this: 11 remove single subflow syn[ ok ] - synack[ ok ] - ack[ ok ] rm [ ok ] - sf [ ok ] 12 remove multiple subflows syn[ ok ] - synack[ ok ] - ack[ ok ] rm [ ok ] - sf [ ok ] 13 remove single address syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] rm [ ok ] - sf [ ok ] 14 remove subflow and signal syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] rm [ ok ] - sf [ ok ] 15 remove subflows and signal syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] rm [ ok ] - sf [ ok ] Suggested-by:

This patch added a new cfg, named cfg_remove in mptcp_connect. This new cfg_remove is copied from cfg_join. The only difference between them is in the do_rnd_write function. Here we slow down the transfer process of all data to let the RM_ADDR suboption can be sent and received completely. Otherwise the remove address and subflow test cases don't work. Suggested-by:

This patch implemented the local subflow removing function, mptcp_pm_remove_subflow, it simply called mptcp_pm_nl_rm_subflow_received under the PM spin lock. We use mptcp_pm_remove_subflow to remove a local subflow, so change it's argument from remote_id to local_id. We check subflow->local_id in mptcp_pm_nl_rm_subflow_received to remove a subflow.

This patch implements the remove announced addr and subflow logic in PM netlink. When the PM netlink removes an address, we traverse all the existing msk sockets to find the relevant sockets. We add a new list named anno_list in mptcp_pm_data, to record all the announced addrs. In the traversing, we check if it has been recorded. If it has been, we trigger the RM_ADDR signal. We also check if this address is in conn_list. If it is, we remove the subflow which using this local address. Since we call mptcp_pm_free_anno_list in mptcp_destroy, we need to move __mptcp_init_sock before the mptcp_is_enabled check in mptcp_init_sock. Suggested-by:

This patch added the RM_ADDR option parsing logic: We parsed the incoming options to find if the rm_addr option is received, and called mptcp_pm_rm_addr_received to schedule PM work to a new status, named MPTCP_PM_RM_ADDR_RECEIVED. PM work got this status, and called mptcp_pm_nl_rm_addr_received to handle it. In mptcp_pm_nl_rm_addr_received, we closed the subflow matching the rm_id, and updated PM counter. Suggested-by:
