The "42f5cda5" commit rightly set SOCK_DONE on peer shutdown, but there is an issue if we receive the SHUTDOWN(RDWR) while the virtio_transport_close_timeout() is scheduled. In this case, when the timeout fires, the SOCK_DONE is already set and the virtio_transport_close_timeout() will not call virtio_transport_reset() and virtio_transport_do_close(). This causes that both sockets remain open and will never be released, preventing the unloading of [virtio|vhost]_transport modules. This patch fixes this issue, calling virtio_transport_reset() and virtio_transport_do_close() when we receive the SHUTDOWN(RDWR) and there is nothing left to read.

While looking at a syzbot KCSAN report [1], I found multiple issues in this code : 1) fib6_nh->last_probe has an initial value of 0. While probably okay on 64bit kernels, this causes an issue on 32bit kernels since the time_after(jiffies, 0 + interval) might be false ~24 days after boot (for HZ=1000) 2) The data-race found by KCSAN I could use READ_ONCE() and WRITE_ONCE(), but we also can take the opportunity of not piling-up too many rt6_probe_deferred() works by using instead cmpxchg() so that only one cpu wins the race.

This patch fixes the problem of the spin locks, originally meant for the netpoll path of hns driver, causing deadlock in the normal NAPI poll path. The issue happened due to the presence of the stray leftover spin lock code related to the netpoll, whose support was earlier removed from the HNS[1], got activated due to enabling of NET_POLL_CONTROLLER switch. Earlier background: The netpoll handling code originally had this bug(as identified by Marc Zyngier[2]) of wrong spin lock API being used which did not disable the interrupts and hence could cause locking issues. i.e. if the lock were first acquired in context to thread like 'ip' util and this lock if ever got later acquired again in context to the interrupt context like TX/RX (Interrupts could always pre-empt the lock holding task and acquire the lock again) and hence could cause deadlock. Proposed Solution: 1. If the netpoll was enabled in the HNS driver, which is not right now, we could have simply used spin_[un]lock_irqsave() 2. But as netpoll is disabled, therefore, it is best to get rid of the existing locks and stray code for now. This should solve the problem reported by Marc.

Jakub Kicinski says: ==================== net/tls: add a TX lock Some time ago Pooja and Mallesham started reporting crashes with an async accelerator. After trying to poke the existing logic into shape I came to the conclusion that it can't be trusted, and to preserve our sanity we should just add a lock around the TX side. First patch removes the sk_write_pending checks from the write space callbacks. Those don't seem to have a logical justification. Patch 2 adds the TX lock and patch 3 associated test (which should hang with current net). Mallesham reports that even with these fixes applied the async accelerator workload still occasionally hangs waiting for socket memory. I suspect that's strictly related to the way async crypto is integrated in TLS, so I think we should get these into net or net-next and move from there. ==================== Signed-off-by: -

TLS TX needs to release and re-acquire the socket lock if send buffer fills up. TLS SW TX path currently depends on only allowing one thread to enter the function by the abuse of sk_write_pending. If another writer is already waiting for memory no new ones are allowed in. This has two problems: - writers don't wake other threads up when they leave the kernel; meaning that this scheme works for single extra thread (second application thread or delayed work) because memory becoming available will send a wake up request, but as Mallesham and Pooja report with larger number of threads it leads to threads being put to sleep indefinitely; - the delayed work does not get _scheduled_ but it may _run_ when other writers are present leading to crashes as writers don't expect state to change under their feet (same records get pushed and freed multiple times); it's hard to reliably bail from the work, however, because the mere presence of a writer does not guarantee that the writer will push pending records before exiting. Ensuring wakeups always happen will make the code basically open code a mutex. Just use a mutex. The TLS HW TX path does not have any locking (not even the sk_write_pending hack), yet it uses a per-socket sg_tx_data array to push records.

sk_write_pending being not zero does not guarantee that partial record will be pushed. If the thread waiting for memory times out the pending record may get stuck. In case of tls_device there is no path where parial record is set and writer present in the first place. Partial record is set only in tls_push_sg() and tls_push_sg() will return an error immediately. All tls_device callers of tls_push_sg() will return (and not wait for memory) if it failed.

The check that the event is actually for this device should be moved from the "port" handler to the net device handler. Otherwise the port handler will deny bonding configuration for other net devices in the same system (like enetc in the LS1028A) that don't have the lag_upper_info->tx_type restriction that ocelot has.

For vlan push action, if eswitch flow source capability is enabled, flow source value compared with MLX5_VPORT_UPLINK enum, to determine uplink port. This lead to syndrome in dmesg if try to add vlan push action. For example: $ tc filter add dev vxlan0 ingress protocol ip prio 1 flower \ enc_dst_port 4789 \ action tunnel_key unset pipe \ action vlan push id 20 pipe \ action mirred egress redirect dev ens1f0_0 $ dmesg ... [ 2456.883693] mlx5_core 0000:82:00.0: mlx5_cmd_check:756:(pid 5273): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xa9c090) Use the correct enum value MLX5_FLOW_CONTEXT_FLOW_SOURCE_UPLINK.
