net: dsa: mv88e6xxx: don't use PHY_DETECT on internal PHY's

2021-10-20T09:45:06+00:00

commit 4a3e0aeddf091f00974b02627c157843ce382a24 upstream. mv88e6xxx_port_ppu_updates() interpretes data in the PORT_STS register incorrectly for internal ports (ie no PPU). In these cases, the PHY_DETECT bit indicates link status. This results in forcing the MAC state whenever the PHY link goes down which is not intended. As a side effect, LED's configured to show link status stay lit even though the physical link is down. Add a check in mac_link_down and mac_link_up to see if it concerns an external port and only then, look at PPU status.

ionic: don't remove netdev->dev_addr when syncing uc list

2021-10-20T09:45:06+00:00

commit 5c976a56570f29aaf4a2f9a1bf99789c252183c9 upstream. Bridging, and possibly other upper stack gizmos, adds the lower device's netdev->dev_addr to its own uc list, and then requests it be deleted when the upper bridge device is removed. This delete request also happens with the bridging vlan_filtering is enabled and then disabled. Bonding has a similar behavior with the uc list, but since it also uses set_mac to manage netdev->dev_addr, it doesn't have the same the failure case. Because we store our netdev->dev_addr in our uc list, we need to ignore the delete request from dev_uc_sync so as to not lose the address and all hope of communicating. Note that ndo_set_mac_address is expressly changing netdev->dev_addr, so no limitation is set there.

net: mscc: ocelot: warn when a PTP IRQ is raised for an unknown skb

2021-10-20T09:45:06+00:00

commit 9fde506e0c53b8309f69b18b4b8144c544b4b3b1 upstream. When skb_match is NULL, it means we received a PTP IRQ for a timestamp ID that the kernel has no idea about, since there is no skb in the timestamping queue with that timestamp ID. This is a grave error and not something to just "continue" over. So print a big warning in case this happens. Also, move the check above ocelot_get_hwtimestamp(), there is no point in reading the full 64-bit current PTP time if we're not going to do anything with it anyway for this skb.

nfp: flow_offload: move flow_indr_dev_register from app init to app start

2021-10-20T09:45:06+00:00

commit 60d950f443a52d950126ad664fbd4a1eb8353dc9 upstream. In commit 74fc4f828769 ("net: Fix offloading indirect devices dependency on qdisc order creation"), it adds a process to trigger the callback to setup the bo callback when the driver regists a callback. In our current implement, we are not ready to run the callback when nfp call the function flow_indr_dev_register, then there will be error message as: kernel: Oops: 0000 [#1] SMP PTI kernel: CPU: 0 PID: 14119 Comm: kworker/0:0 Tainted: G kernel: Workqueue: events work_for_cpu_fn kernel: RIP: 0010:nfp_flower_indr_setup_tc_cb+0x258/0x410 kernel: RSP: 0018:ffffbc1e02c57bf8 EFLAGS: 00010286 kernel: RAX: 0000000000000000 RBX: ffff9c761fabc000 RCX: 0000000000000001 kernel: RDX: 0000000000000001 RSI: fffffffffffffff0 RDI: ffffffffc0be9ef1 kernel: RBP: ffffbc1e02c57c58 R08: ffffffffc08f33aa R09: ffff9c6db7478800 kernel: R10: 0000009c003f6e00 R11: ffffbc1e02800000 R12: ffffbc1e000d9000 kernel: R13: ffffbc1e000db428 R14: ffff9c6db7478800 R15: ffff9c761e884e80 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 kernel: CR2: fffffffffffffff0 CR3: 00000009e260a004 CR4: 00000000007706f0 kernel: DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 kernel: DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 kernel: PKRU: 55555554 kernel: Call Trace: kernel: ? flow_indr_dev_register+0xab/0x210 kernel: ? __cond_resched+0x15/0x30 kernel: ? kmem_cache_alloc_trace+0x44/0x4b0 kernel: ? nfp_flower_setup_tc+0x1d0/0x1d0 [nfp] kernel: flow_indr_dev_register+0x158/0x210 kernel: ? tcf_block_unbind+0xe0/0xe0 kernel: nfp_flower_init+0x40b/0x650 [nfp] kernel: nfp_net_pci_probe+0x25f/0x960 [nfp] kernel: ? nfp_rtsym_read_le+0x76/0x130 [nfp] kernel: nfp_pci_probe+0x6a9/0x820 [nfp] kernel: local_pci_probe+0x45/0x80 So we need to call flow_indr_dev_register in app start process instead of init stage.

mqprio: Correct stats in mqprio_dump_class_stats().

2021-10-20T09:45:06+00:00

commit 14132690860e4d06aa3e1c4d7d8e9866ba7756dd upstream. Introduction of lockless subqueues broke the class statistics. Before the change stats were accumulated in `bstats' and `qstats' on the stack which was then copied to struct gnet_dump. After the change the `bstats' and `qstats' are initialized to 0 and never updated, yet still fed to gnet_dump. The code updates the global qdisc->cpu_bstats and qdisc->cpu_qstats instead, clobbering them. Most likely a copy-paste error from the code in mqprio_dump(). __gnet_stats_copy_basic() and __gnet_stats_copy_queue() accumulate the values for per-CPU case but for global stats they overwrite the value, so only stats from the last loop iteration / tc end up in sch->[bq]stats. Use the on-stack [bq]stats variables again and add the stats manually in the global case.
