Host routes that perform decapsulation of IP in IP tunnels have a special adjacency entry linked to them. This entry stores information such as the expected underlay source IP. When the route is deleted this entry needs to be freed. The allocation of the adjacency entry happens in mlxsw_sp_fib4_entry_type_set(), but it is freed in mlxsw_sp_fib4_node_entry_unlink(). Create a new function - mlxsw_sp_fib4_entry_type_unset() - and free the adjacency entry there. This will allow us to consolidate mlxsw_sp_fib{4,6}_node_entry_unlink() in the next patch.

The original patch bringed in the "SCTP ACK tracking trace event" feature was committed at Dec.20, 2017, it replaced jprobe usage with trace events, and bringed in two trace events, one is TRACE_EVENT(sctp_probe), another one is TRACE_EVENT(sctp_probe_path). The original patch intended to trigger the trace_sctp_probe_path in TRACE_EVENT(sctp_probe) as below code, +TRACE_EVENT(sctp_probe, + + TP_PROTO(const struct sctp_endpoint *ep, + const struct sctp_association *asoc, + struct sctp_chunk *chunk), + + TP_ARGS(ep, asoc, chunk), + + TP_STRUCT__entry( + __field(__u64, asoc) + __field(__u32, mark) + __field(__u16, bind_port) + __field(__u16, peer_port) + __field(__u32, pathmtu) + __field(__u32, rwnd) + __field(__u16, unack_data) + ), + + TP_fast_assign( + struct sk_buff *skb = chunk->skb; + + __entry->asoc = (unsigned long)asoc; + __entry->mark = skb->mark; + __entry->bind_port = ep->base.bind_addr.port; + __entry->peer_port = asoc->peer.port; + __entry->pathmtu = asoc->pathmtu; + __entry->rwnd = asoc->peer.rwnd; + __entry->unack_data = asoc->unack_data; + + if (trace_sctp_probe_path_enabled()) { + struct sctp_transport *sp; + + list_for_each_entry(sp, &asoc->peer.transport_addr_list, + transports) { + trace_sctp_probe_path(sp, asoc); + } + } + ), But I found it did not work when I did testing, and trace_sctp_probe_path had no output, I finally found that there is trace buffer lock operation(trace_event_buffer_reserve) in include/trace/trace_events.h: static notrace void \ trace_event_raw_event_##call(void *__data, proto) \ { \ struct trace_event_file *trace_file = __data; \ struct trace_event_data_offsets_##call __maybe_unused __data_offsets;\ struct trace_event_buffer fbuffer; \ struct trace_event_raw_##call *entry; \ int __data_size; \ \ if (trace_trigger_soft_disabled(trace_file)) \ return; \ \ __data_size = trace_event_get_offsets_##call(&__data_offsets, args); \ \ entry = trace_event_buffer_reserve(&fbuffer, trace_file, \ sizeof(*entry) + __data_size); \ \ if (!entry) \ return; \ \ tstruct \ \ { assign; } \ \ trace_event_buffer_commit(&fbuffer); \ } The reason caused no output of trace_sctp_probe_path is that trace_sctp_probe_path written in TP_fast_assign part of TRACE_EVENT(sctp_probe), and it will be placed( { assign; } ) after the trace_event_buffer_reserve() when compiler expands Macro, entry = trace_event_buffer_reserve(&fbuffer, trace_file, \ sizeof(*entry) + __data_size); \ \ if (!entry) \ return; \ \ tstruct \ \ { assign; } \ so trace_sctp_probe_path finally can not acquire trace_event_buffer and return no output, that is to say the nest of tracepoint entry function is not allowed. The function call flow is: trace_sctp_probe() -> trace_event_raw_event_sctp_probe() -> lock buffer -> trace_sctp_probe_path() -> trace_event_raw_event_sctp_probe_path() --nested -> buffer has been locked and return no output. This patch is to remove trace_sctp_probe_path from the TP_fast_assign part of TRACE_EVENT(sctp_probe) to avoid the nest of entry function, and trigger sctp_probe_path_trace in sctp_outq_sack. After this patch, you can enable both events individually, # cd /sys/kernel/debug/tracing # echo 1 > events/sctp/sctp_probe/enable # echo 1 > events/sctp/sctp_probe_path/enable Or, you can enable all the events under sctp. # echo 1 > events/sctp/enable Signed-off-by: Kevin Kou <qdkevin.kou@gmail.com> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.

Richard Cochran says: ==================== Peer to Peer One-Step time stamping This series adds support for PTP (IEEE 1588) P2P one-step time stamping along with a driver for a hardware device that supports this. If the hardware supports p2p one-step, it subtracts the ingress time stamp value from the Pdelay_Request correction field. The user space software stack then simply copies the correction field into the Pdelay_Response, and on transmission the hardware adds the egress time stamp into the correction field. This new functionality extends CONFIG_NETWORK_PHY_TIMESTAMPING to cover MII snooping devices, but it still depends on phylib, just as that option does. Expanding beyond phylib is not within the scope of the this series. User space support is available in the current linuxptp master branch. - Patch 1 adds phy_device methods for existing time stamping fields. - Patches 2-5 convert the stack and drivers to the new methods. - Patch 6 moves code around the dp83640 driver. - Patches 7-10 add support for MII time stamping in non-PHY devices. - Patch 11 adds the new P2P 1-step option. - Patch 12 adds a driver implementing the new option. Thanks, Richard Changed in v9: ~~~~~~~~~~~~~~ - Fix two more drivers' switch/case blocks WRT the new HWTSTAMP ioctl. - Picked up two more review tags from Andrew.

While PHY time stamping drivers can simply attach their interface directly to the PHY instance, stand alone drivers require support in order to manage their services. Non-PHY MII time stamping drivers have a control interface over another bus like I2C, SPI, UART, or via a memory mapped peripheral. The controller device will be associated with one or more time stamping channels, each of which sits snoops in on a MII bus. This patch provides a glue layer that will enable time stamping channels to find their controlling device.

Currently the stack supports time stamping in PHY devices. However, there are newer, non-PHY devices that can snoop an MII bus and provide time stamps. In order to support such devices, this patch introduces a new interface to be used by both PHY and non-PHY devices.

An upcoming patch will change how the PHY time stamping functions are registered with the networking stack, and adapting this driver would entail adding forward declarations for four time stamping methods. However, forward declarations are considered to be stylistic defects. This patch avoids the issue by moving the probe and remove methods immediately above the phy_driver interface structure.

Ido Schimmel says: ==================== Simplify IPv6 route offload API Motivation ========== This is the IPv6 counterpart of "Simplify IPv4 route offload API" [1]. The aim of this patch set is to simplify the IPv6 route offload API by making the stack a bit smarter about the notifications it is generating. This allows driver authors to focus on programming the underlying device instead of having to duplicate the IPv6 route insertion logic in their driver, which is error-prone. Details ======= Today, whenever an IPv6 route is added or deleted a notification is sent in the FIB notification chain and it is up to offload drivers to decide if the route should be programmed to the hardware or not. This is not an easy task as in hardware routes are keyed by {prefix, prefix length, table id}, whereas the kernel can store multiple such routes that only differ in metric / nexthop info. This series makes sure that only routes that are actually used in the data path are notified to offload drivers. This greatly simplifies the work these drivers need to do, as they are now only concerned with programming the hardware and do not need to replicate the IPv6 route insertion logic and store multiple identical routes. The route that is notified is the first route in the IPv6 FIB node, which represents a single prefix and length in a given table. In case the route is deleted and there is another route with the same key, a replace notification is emitted. Otherwise, a delete notification is emitted. Unlike IPv4, in IPv6 it is possible to append individual nexthops to an existing multipath route. Therefore, in addition to the replace and delete notifications present in IPv4, an append notification is also used. Testing ======= To ensure there is no degradation in route insertion rates, I averaged the insertion rate of 512k routes (/64 and /128) over 50 runs. Did not observe any degradation. Functional tests are available here [2]. They rely on route trap indication, which is added in a subsequent patch set. In addition, I have been running syzkaller for the past couple of weeks with debug options enabled. Did not observe any problems. Patch set overview ================== Patches #1-#7 gradually introduce the new FIB notifications Patch #8 converts mlxsw to use the new notifications Patch #9 remove the old notifications [1] https://patchwork.ozlabs.org/cover/1209738/ [2] https://github.com/idosch/linux/tree/fib-notifier ==================== Signed-off-by: David S.

For the purpose of route offload, when a single route is deleted, it is only of interest if it is the first route in the node or if it is sibling to such a route. In the first case, distinguish between several possibilities: 1. Route is the last route in the node. Emit a delete notification 2. Route is followed by a non-multipath route. Emit a replace notification for the non-multipath route. 3. Route is followed by a multipath route. Emit a replace notification for the multipath route. In the second case, only emit a delete notification to ensure the route is no longer used as a valid nexthop.

When a new listener is registered to the FIB notification chain it receives a dump of all the available routes in the system. Instead, make sure to only replay the IPv6 routes that are actually used in the data path and are of any interest to the new listener. This is done by iterating over all the routing tables in the given namespace, but from each traversed node only the first route ('leaf') is notified. Multipath routes are notified in a single notification instead of one for each nexthop. Add fib6_rt_dump_tmp() to do that. Later on in the patch set it will be renamed to fib6_rt_dump() instead of the existing one.

In a similar fashion to previous patches, only notify the new multipath route if it is the first route in the node or if it was appended to such route. The type of the notification (replace vs. append) is determined based on the number of routes added ('nhn') and the number of sibling routes. If the two do not match, then an append notification should be sent.

fib6_add_rt2node() takes care of adding a single route ('struct fib6_info') to a FIB node. The route in question should only be notified in case it is added as the first route in the node (lowest metric) or if it is added as a sibling route to the first route in the node. The first criterion can be tested by checking if the route is pointed to by 'fn->leaf'. The second criterion can be tested by checking the new 'notify_sibling_rt' variable that is set when the route is added as a sibling to the first route in the node.
