Andrew reported a bonding issue that if we put an active-back bond on top of a 802.3ad bond interface. When the 802.3ad bond's speed/duplex changed dynamically. The upper bonding interface's speed/duplex can't be changed at the same time, which will show incorrect speed. Fix it by updating the port speed when calling ethtool. Reported-by:

When the ifdown function in the dst_ops structure is referenced, the input parameter 'how' is always true. In the current implementation of the ifdown interface, ip6_dst_ifdown does not use the input parameter 'how', xfrm6_dst_ifdown and xfrm4_dst_ifdown functions use the input parameter 'unregister'. But false judgment on 'unregister' in xfrm6_dst_ifdown and xfrm4_dst_ifdown is false, so remove the input parameter 'how' in ifdown function. Signed-off-by:

Implement pcs_disable op which resets the stored interface mode to PHY_INTERFACE_MODE_NA to trigger a full reconfiguration once the LynxI PCS driver had previously been deselected in favor of another PCS driver such as the to-be-added driver for the USXGMII PCS found in MT7988.

Hangbin Liu says: ==================== ipv6: update route when delete source address Currently, when remove an address, the IPv6 route will not remove the prefer source address when the address is bond to other device. Fix this issue and add related tests as Ido and David suggested. ==================== Signed-off-by: -
Hangbin Liu authored
Add a test case for IPv6 source address delete. As David suggested, add tests: - Single device using src address - Two devices with the same source address - VRF with single device using src address - VRF with two devices using src address As Ido points out, in IPv6, the preferred source address is looked up in the same VRF as the first nexthop device. This will give us similar results to IPv4 if the route is installed in the same VRF as the nexthop device, but not when the nexthop device is enslaved to a different VRF. So add tests: - src address and nexthop dev in same VR - src address and nexthop device in different VRF The link local address delete logic is different from the global address. It should only affect the associate device it bonds to. So add tests cases for link local address testing. Here is the test result: IPv6 delete address route tests Single device using src address TEST: Prefsrc removed when src address removed on other device [ OK ] Two devices with the same source address TEST: Prefsrc not removed when src address exist on other device [ OK ] TEST: Prefsrc removed when src address removed on all devices [ OK ] VRF with single device using src address TEST: Prefsrc removed when src address removed on other device [ OK ] VRF with two devices using src address TEST: Prefsrc not removed when src address exist on other device [ OK ] TEST: Prefsrc removed when src address removed on all devices [ OK ] src address and nexthop dev in same VRF TEST: Prefsrc removed from VRF when source address deleted [ OK ] TEST: Prefsrc in default VRF not removed [ OK ] TEST: Prefsrc not removed from VRF when source address exist [ OK ] TEST: Prefsrc in default VRF removed [ OK ] src address and nexthop device in different VRF TEST: Prefsrc not removed from VRF when nexthop dev in diff VRF [ OK ] TEST: Prefsrc not removed in default VRF [ OK ] TEST: Prefsrc removed from VRF when nexthop dev in diff VRF [ OK ] TEST: Prefsrc removed in default VRF [ OK ] Table ID 0 TEST: Prefsrc removed from default VRF when source address deleted [ OK ] Link local source route TEST: Prefsrc not removed when delete ll addr from other dev [ OK ] TEST: Prefsrc removed when delete ll addr [ OK ] TEST: Prefsrc not removed when delete ll addr from other dev [ OK ] TEST: Prefsrc removed even ll addr still exist on other dev [ OK ] Tests passed: 19 Tests failed: 0 Suggested-by: -

After deleting an IPv6 address on an interface and cleaning up the related preferred source entries, it is important to ensure that all routes associated with the deleted address are properly cleared. The current implementation of rt6_remove_prefsrc() only checks the preferred source addresses bound to the current device. However, there may be routes that are bound to other devices but still utilize the same preferred source address. To address this issue, it is necessary to also delete entries that are bound to other interfaces but share the same source address with the current device. Failure to delete these entries would leave routes that are bound to the deleted address unclear. Here is an example reproducer (I have omitted unrelated routes): + ip link add dummy1 type dummy + ip link add dummy2 type dummy + ip link set dummy1 up + ip link set dummy2 up + ip addr add 1:2:3:4::5/64 dev dummy1 + ip route add 7:7:7:0::1 dev dummy1 src 1:2:3:4::5 + ip route add 7:7:7:0::2 dev dummy2 src 1:2:3:4::5 + ip -6 route show 1:2:3:4::/64 dev dummy1 proto kernel metric 256 pref medium 7:7:7::1 dev dummy1 src 1:2:3:4::5 metric 1024 pref medium 7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium + ip addr del 1:2:3:4::5/64 dev dummy1 + ip -6 route show 7:7:7::1 dev dummy1 metric 1024 pref medium 7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium As Ido reminds, in IPv6, the preferred source address is looked up in the same VRF as the first nexthop device, which is different with IPv4. So, while removing the device checking, we also need to add an ipv6_chk_addr() check to make sure the address does not exist on the other devices of the rt nexthop device's VRF. After fix: + ip addr del 1:2:3:4::5/64 dev dummy1 + ip -6 route show 7:7:7::1 dev dummy1 metric 1024 pref medium 7:7:7::2 dev dummy2 metric 1024 pref medium Reported-by:

As the initial commit 1a017276 ("selftests: Add VRF route leaking tests") said, the IPv6 MTU test fails as source address selection picking ::1. Every time we run the selftest this one report failed. There seems not much meaning to keep reporting a failure for 3 years that no one plan to fix/update. Let't just skip this one first. We can add it back when the issue fixed. Signed-off-by:

Setting IP_RECVERR and IPV6_RECVERR options to zero currently purges the socket error queue, which was probably not expected for zerocopy and tx_timestamp users. I discovered this issue while preparing commit 6b5f43ea ("inet: move inet->recverr to inet->inet_flags"), I presume this change does not need to be backported to stable kernels.

The user ports use RSGMII, but we don't have that, and DT doesn't specify a phy interface mode, so phylib defaults to GMII. These support 1G, 100M and 10M with flow control. It is unknown whether asymetric pause is supported at all speeds. The CPU port uses MII/GMII/RGMII/REVMII by hardware pin strapping, and support speeds specific to each, with full duplex only supported in some modes. Flow control may be supported again by hardware pin strapping, and theoretically is readable through a register but no information is given in the datasheet for that. So, we do a best efforts - and be lenient. Signed-off-by:

Currently any error during render leads to output an empty file. That is quite annoying when using tools/net/ynl/ynl-regen.sh which git greps files with content of "YNL-GEN.." and therefore ignores empty files. So once you fail to regen, you have to checkout the file. Avoid that by rendering to a temporary file first, only at the end copy the content to the actual destination. Signed-off-by:

Add vendor unique experimental options area in clc handshake. In clc accept and confirm msg, vendor unique experimental options use the 16-Bytes reserved field, which defined in struct smc_clc_fce_gid_ext in previous version. Because of the struct smc_clc_first_contact_ext is widely used and limit the scope of modification, this patch moves the 16-Bytes reserved field out of struct smc_clc_fce_gid_ext, and followed with the struct smc_clc_first_contact_ext in a new struct names struct smc_clc_first_contact_ext_v2x. For SMC-R first connection, in previous version, the struct smc_clc_ first_contact_ext and the 16-Bytes reserved field has already been included in clc accept and confirm msg. Thus, this patch use struct smc_clc_first_contact_ext_v2x instead of the struct smc_clc_first_ contact_ext and the 16-Bytes reserved field in SMC-R clc accept and confirm msg is compatible with previous version. For SMC-D first connection, in previous version, only the struct smc_ clc_first_contact_ext is included in clc accept and confirm msg, and the 16-Bytes reserved field is not included. Thus, when the negotiated smc release version is the version before v2.1, we still use struct smc_clc_first_contact_ext for compatible consideration. If the negotiated smc release version is v2.1 or later, use struct smc_clc_first_contact_ ext_v2x instead. Signed-off-by:

Enabling BIG TCP on a low end platform apparently increased chances of getting flows locked on one busy TX queue. A similar problem was handled in commit 9b462d02 ("tcp: TCP Small Queues and strange attractors"), but the strategy worked for either bulk flows, or 'large enough' RPC. BIG TCP changed how large RPC needed to be to enable the work around: If RPC fits in a single skb, TSQ never triggers. Root cause for the problem is a busy TX queue, with delayed TX completions. This patch changes how we set skb->ooo_okay to detect the case TX completion was not done, but incoming ACK already was processed and emptied rtx queue. Update the comment to explain the tricky details. Signed-off-by:
