vmxnet3 fails to set netif_carrier_off on probe, meaning that when an interface is opened the __LINK_STATE_NOCARRIER bit is already cleared, and so /sys/class/net/<ifname>/operstate remains in the unknown state. Correct this by setting netif_carrier_off on probe, like other drivers do. Also, while we're at it, lets remove the netif_carrier_ok checks from the link_state_update function, as that check is atomically contained within the netif_carrier_[on|off] functions anyway Tested successfully by myself Signed-off-by: NNeil Horman <nhorman@tuxdriver.com> CC: "David S.

In rare instances, memory errors have been detected in the internal packet buffer memory on I217/I218 when stressed under certain environmental conditions. Enable Error Correcting Code (ECC) in hardware to catch both correctable and uncorrectable errors. Correctable errors will be handled by the hardware. Uncorrectable errors in the packet buffer will cause the packet to be received with an error indication in the buffer descriptor causing the packet to be discarded. If the uncorrectable error is in the descriptor itself, the hardware will stop and interrupt the driver indicating the error. The driver will then reset the hardware in order to clear the error and restart. Both types of errors will be accounted for in statistics counters.

We forbid polling, writing and reading when the file were detached, this may complex the user in several cases: - when guest pass some buffers to vhost/qemu and then disable some queues, host/qemu needs to do its own cleanup on those buffers which is complex sometimes. We can do this simply by allowing a user can still write to an disabled queue. Write to an disabled queue will cause the packet pass to the kernel and read will get nothing. - align the polling behavior with macvtap which never fails when the queue is created. This can simplify the polling errors handling of its user (e.g vhost) We can simply achieve this by don't assign NULL to tfile->tun when detached.

Currently, the polling errors were ignored, which can lead following issues: - vhost remove itself unconditionally from waitqueue when stopping the poll, this may crash the kernel since the previous attempt of starting may fail to add itself to the waitqueue - userspace may think the backend were successfully set even when the polling failed. Solve this by: - check poll->wqh before trying to remove from waitqueue - report polling errors in vhost_poll_start(), tx_poll_start(), the return value will be checked and returned when userspace want to set the backend After this fix, there still could be a polling failure after backend is set, it will addressed by the next patch.

The delay calculation with the rate extension introduces in v3.3 does not properly work, if other packets are still queued for transmission. For the delay calculation to work, both delay types (latency and delay introduces by rate limitation) have to be handled differently. The latency delay for a packet can overlap with the delay of other packets. The delay introduced by the rate however is separate, and can only start, once all other rate-introduced delays finished. Latency delay is from same distribution for each packet, rate delay depends on the packet size. .: latency delay -: rate delay x: additional delay we have to wait since another packet is currently transmitted .....---- Packet 1 .....xx------ Packet 2 .....------ Packet 3 ^^^^^ latency stacks ^^ rate delay doesn't stack ^^ latency stacks -----> time When a packet is enqueued, we first consider the latency delay. If other packets are already queued, we can reduce the latency delay until the last packet in the queue is send, however the latency delay cannot be <0, since this would mean that the rate is overcommitted. The new reference point is the time at which the last packet will be send. To find the time, when the packet should be send, the rate introduces delay has to be added on top of that.

由 Tom Parkin 提交于
If a tunnel socket is created by userspace, l2tp hooks the socket destructor in order to clean up resources if userspace closes the socket or crashes. It also caches a pointer to the struct sock for use in the data path and in the netlink interface. While it is safe to use the cached sock pointer in the data path, where the skb references keep the socket alive, it is not safe to use it elsewhere as such access introduces a race with userspace closing the socket. In particular, l2tp_tunnel_delete is prone to oopsing if a multithreaded userspace application closes a socket at the same time as sending a netlink delete command for the tunnel. This patch fixes this oops by forcing l2tp_tunnel_delete to explicitly look up a tunnel socket held by userspace using sockfd_lookup().

commit f96972f2 "kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()" added a call to disable_nonboot_cpus() on kernel_restart(), which tries to shutdown all the CPUs except the first one. The issue with the PA Semi, is that it does not support CPU hotplug. When the call is made to __cpu_down(), it calls the notifiers CPU_DOWN_PREPARE, and then tries to take the CPU down. One of the notifiers to the CPU hotplug code, is the cpufreq. The DOWN_PREPARE will call __cpufreq_remove_dev() which calls cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O that is used by an interrupt that goes off constantly (system_reset_common, but it goes off during normal system operations too). I'm not sure exactly what this interrupt does. Running a simple function trace, you can see it goes off quite a bit: # tracer: function # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | <idle>-0 [001] 1558.859363: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.860112: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861109: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [001] 1558.861361: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861437: .pasemi_system_reset_exception <-.system_reset_exception When the region is unmapped, the system crashes with: Disabling non-boot CPUs ...

The IOMMU may stop processing page translations due to a perceived lack of credits for writing upstream peripheral page service request (PPR) or event logs. If the L2B miscellaneous clock gating feature is enabled the IOMMU does not properly register credits after the log request has completed, leading to a potential system hang. BIOSes are supposed to disable L2B micellaneous clock gating by setting L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b. This patch corrects that for those which do not enable this workaround.

dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum offload, ..), but it can also be put in a dm9601 compatible mode, allowing us to reuse the existing driver. This does mean that the extended features like checksum offload cannot be used, but that's hardly critical on a 100mbps interface. Thanks to Sławek Wernikowski <slawek@wernikowski.net> for providing me with a dm9620 based device to test. Signed-off-by: NPeter Korsgaard <jacmet@sunsite.dk> Signed-off-by: NDavid S.

Like several other PHY devices which support RGMII, the IC+1001 allows additional delays to by added to the RX_CLK and TX_CLK signals to compensate for skew between the clock and data signals. Previously this was always enabled, but this change makes use of the different RGMII interface modes to allow the user to specify whether this should be enabled.

While sctp handling a duplicate COOKIE-ECHO and the action is 'Association restart', sctp_sf_do_dupcook_a() will processing the unexpected COOKIE-ECHO for peer restart, but it does not set the association state to SCTP_STATE_ESTABLISHED, so the association could stuck in SCTP_STATE_SHUTDOWN_PENDING state forever. This violates the sctp specification: RFC 4960 5.2.4. Handle a COOKIE ECHO when a TCB Exists Action A) In this case, the peer may have restarted. ..... After this, the endpoint shall enter the ESTABLISHED state. To resolve this problem, adding a SCTP_CMD_NEW_STATE cmd to the command list before SCTP_CMD_REPLY cmd, this will set the restart association to SCTP_STATE_ESTABLISHED state properly and also avoid I-bit being set in the DATA chunk header when COOKIE_ACK is bundled with DATA chunks.

We did this for IPv4 in b49d3c1e "net: ipmr: limit MRT_TABLE identifiers" but we need to do it for IPv6 as well. On IPv6 the name is "pim6reg" instead of "pimreg" so there is one less digit allowed.

commit 9992c2e2 (net: cdc_ncm: workaround for missing CDC Union) added code to lookup an IAD for the interface we are probing. This is redundant.
