Alexis Lothoré says: ==================== net: dsa: rzn1-a5psw: fix STP states handling This small series fixes STP support and while adding a new function to enable/disable learning, use that to disable learning on standalone ports at switch setup as reported by Vladimir Oltean. This series was initially submitted on net-next by Clement Leger, but some career evolutions has made him hand me over those topics. Also, this new revision is submitted on net instead of net-next for V1 based on Vladimir Oltean's suggestion Changes since v2: - fix commit split by moving A5PSW_MGMT_CFG_ENABLE in relevant commit - fix reverse christmas tree ordering in a5psw_port_stp_state_set Changes since v1: - fix typos in commit messages and doc - re-split STP states handling commit - add Fixes: tag and new Signed-off-by - submit series as fix on net instead of net-next - split learning and blocking setting functions - remove unused define A5PSW_PORT_ENA_TX_SHIFT - add boolean for tx/rx enabled for clarity ==================== Signed-off-by: David S.

2023-05-13net: dsa: rzn1-a5psw: disable learning for standalone portsClément Léger
When ports are in standalone mode, they should have learning disabled to avoid adding new entries in the MAC lookup table which might be used by other bridge ports to forward packets. While adding that, also make sure learning is enabled for CPU port.

2023-05-13net: dsa: rzn1-a5psw: fix STP states handlingAlexis Lothoré
stp_set_state() should actually allow receiving BPDU while in LEARNING mode which is not the case. Additionally, the BLOCKEN bit does not actually forbid sending forwarded frames from that port. To fix this, add a5psw_port_tx_enable() function which allows to disable TX. However, while its name suggest that TX is totally disabled, it is not and can still allow to send BPDUs even if disabled. This can be done by using forced forwarding with the switch tagging mechanism but keeping "filtering" disabled (which is already the case in the rzn1-a5sw tag driver). With these fixes, STP support is now functional.

Currently, management frame were discarded before reaching the CPU port due to a misconfiguration of the MGMT_CONFIG register. Enable them by setting the correct value in this register in order to correctly receive management frame and handle STP.

In dvb_demux.c, some logics exist which compare the expected continuity counter and the real continuity counter. If they are not matched each other, both of the expected continuity counter and the real continuity counter should be printed. But there exists a bug that the expected continuity counter is not correctly printed. The expected continuity counter is replaced with the real countinuity counter + 1 so that the epected continuity counter is not correclty printed. This is wrong. This bug is fixed.

2023-05-12vsock: avoid to close connected socket after the timeoutZhuang Shengen
When client and server establish a connection through vsock, the client send a request to the server to initiate the connection, then start a timer to wait for the server's response. When the server's RESPONSE message arrives, the timer also times out and exits. The server's RESPONSE message is processed first, and the connection is established. However, the client's timer also times out, the original processing logic of the client is to directly set the state of this vsock to CLOSE and return ETIMEDOUT. It will not notify the server when the port is released, causing the server port remain. when client's vsock_connect timeout，it should check sk state is ESTABLISHED or not. if sk state is ESTABLISHED, it means the connection is established, the client should not set the sk state to CLOSE Note: I encountered this issue on kernel-4.18, which can be fixed by this patch.

As such, creating a vlan and trying to run ping through would result in no traffic passing. Fix that by refactoring tx_flags variable into flags only and a separate variable that holds VLAN ID.

In the (unlikely) event that pm_runtime_get() (disguised as pm_runtime_resume_and_get()) fails, the remove callback returned an error early. The problem with this is that the driver core ignores the error value and continues removing the device. This results in a resource leak. Worse the devm allocated resources are freed and so if a callback of the driver is called later the register mapping is already gone which probably results in a crash.

2023-05-11devlink: change per-devlink netdev notifier to static oneJiri Pirko
The commit 565b4824c39f ("devlink: change port event netdev notifier from per-net to global") changed original per-net notifier to be per-devlink instance. That fixed the issue of non-receiving events of netdev uninit if that moved to a different namespace. That worked fine in -net tree. However, later on when commit ee75f1fc44dd ("net/mlx5e: Create separate devlink instance for ethernet auxiliary device") and commit 72ed5d5624af ("net/mlx5: Suspend auxiliary devices only in case of PCI device suspend") were merged, a deadlock was introduced when removing a namespace with devlink instance with another nested instance. Here there is the bad flow example resulting in deadlock with mlx5: net_cleanup_work -> cleanup_net (takes down_read(&pernet_ops_rwsem) -> devlink_pernet_pre_exit() -> devlink_reload() -> mlx5_devlink_reload_down() -> mlx5_unload_one_devl_locked() -> mlx5_detach_device() -> del_adev() -> mlx5e_remove() -> mlx5e_destroy_devlink() -> devlink_free() -> unregister_netdevice_notifier() (takes down_write(&pernet_ops_rwsem) Steps to reproduce: $ modprobe mlx5_core $ ip netns add ns1 $ devlink dev reload pci/0000:08:00.0 netns ns1 $ ip netns del ns1 Resolve this by converting the notifier from per-devlink instance to a static one registered during init phase and leaving it registered forever. Use this notifier for all devlink port instances created later on. Note what a tree needs this fix only in case all of the cited fixes commits are present.

Andrea Mayer says: ==================== selftests: seg6: make srv6_end_dt4_l3vpn_test more robust This pachset aims to improve and make more robust the selftests performed to check whether SRv6 End.DT4 beahvior works as expected under different system configurations. Some Linux distributions enable Deduplication Address Detection and Reverse Path Filtering mechanisms by default which can interfere with SRv6 End.DT4 behavior and cause selftests to fail. The following patches improve selftests for End.DT4 by taking these two mechanisms into account. Specifically: - patch 1/2: selftests: seg6: disable DAD on IPv6 router cfg for srv6_end_dt4_l3vpn_test - patch 2/2: selftets: seg6: disable rp_filter by default in srv6_end_dt4_l3vpn_test ==================== Link: https://lore.kernel.org/r/20230510111638.12408-1-andrea.mayer@uniroma2.it Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-05-11selftets: seg6: disable rp_filter by default in srv6_end_dt4_l3vpn_testAndrea Mayer
On some distributions, the rp_filter is automatically set (=1) by default on a netdev basis (also on VRFs). In an SRv6 End.DT4 behavior, decapsulated IPv4 packets are routed using the table associated with the VRF bound to that tunnel. During lookup operations, the rp_filter can lead to packet loss when activated on the VRF. Therefore, we chose to make this selftest more robust by explicitly disabling the rp_filter during tests (as it is automatically set by some Linux distributions).

2023-05-11selftests: seg6: disable DAD on IPv6 router cfg for srv6_end_dt4_l3vpn_testAndrea Mayer
The srv6_end_dt4_l3vpn_test instantiates a virtual network consisting of several routers (rt-1, rt-2) and hosts. When the IPv6 addresses of rt-{1,2} routers are configured, the Deduplicate Address Detection (DAD) kicks in when enabled in the Linux distros running the selftests. DAD is used to check whether an IPv6 address is already assigned in a network. Such a mechanism consists of sending an ICMPv6 Echo Request and waiting for a reply. As the DAD process could take too long to complete, it may cause the failing of some tests carried out by the srv6_end_dt4_l3vpn_test script. To make the srv6_end_dt4_l3vpn_test more robust, we disable DAD on routers since we configure the virtual network manually and do not need any address deduplication mechanism at all.
