2022-07-19linux-cp: API downgrade due to namespace keywordMatthew Smith1-0/+5
Type: fix A user had trouble compiling C++ code to work with the linux-cp APIs because some messages contain a field called namespace, which is a reserved word for C++. We wish to rename those fields so the messages which are affected are being set to in_progress. Change-Id: I3bd1dc898c146a9980161a562b2b453313bb58fd Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2022-07-12perfmon: enable perfmon plugin for ArmZachary Leaf13-37/+659
This patch enables statistics from the Arm PMUv3 through the perfmon plugin. In comparison to using the Linux "perf" tool, it allows obtaining direct, per node level statistics (rather than per thread). By accessing the PMU counter registers directly from userspace, we can avoid the overhead of using a read() system call and get more accurate and fine grained statistics about the running of individual nodes. A demo of perfmon on Arm can be found at: https://asciinema.org/a/egVNN1OF7JEKHYmfl5bpDYxfF *Important Note* Perfmon on Arm is dependent on and works only on Linux kernel versions of v5.17+ as this is when userspace access to Arm perf counters was included. On most Arm systems, a maximum of 7 PMU events can be configured at once - (6x PMU events + 1x CPU_CYCLE counter). If some perf counters are in use elsewhere by other applications, and there are insufficient counters remaining to open the bundle, the perf_event_open call will fail (provided the events are grouped with the group_fd param, which perfmon currently utilises). See arm/events.h for a list of PMUv3 events available, although it is implementation defined whether most events are implemented or not. Only a small set of 7 events is required to be implemented in Armv8.0, with some additional events required in later versions. As such, depending on the implementation, some statistics may not be available. See Arm Architecture Reference Manual for Armv8-A, D7.10.2 "The PMU event number space and common events" for more information. arm/events.c:arm_init() gets information from the sysfs about what events are implemented on a particular CPU at runtime. Arm's implementation of the perfmon source callback .bundle_support uses this information to disable unsupported events in a bundle, or in the case no events are supported, disable the entire bundle. Where a particular event in a bundle is not implemented, the statistic for that event is shown as '-' in the 'show perfmon statistics' cli output, by disabling the column. There is additional code in perfmon.c to only open events which are marked as implemented. Since we're only opening and reading events that are implemented, some extra logic is required in cli.c to re-align either perfmon_node_stats_t or perfmon_reading_t with the column headings configured in each bundle, taking into account disabled columns. Userspace access to perf counters is disabled by default, and needs to be enabled with 'sudo sysctl kernel/perf_user_access=1'. There is a check built into the Arm event source init function (arm/events.c:arm_init) to check that userspace reading of perf counters is enabled in the /proc/sys/kernel/perf_user_access file. If the above file does not exist, it means the kernel version is unsupported. Users without a supported kernel will see a warning message, and no Arm bundles will be registered to use in perfmon. Enabling/using plugin: - include the following in startup.conf: - plugins { plugin perfmon_plugin.so { enable } - 'show perfmon bundle [verbose]' - show available statistics bundles - 'perfmon start bundle <bundle-name>' - enable and start logging - 'perfmon stop' - stop logging - 'show perfmon statistics' - show output For a general guide on using and understanding Arm PMUv3 events, see https://community.arm.com/arm-community-blogs/b/tools-software-ides-blog/posts/arm-neoverse-n1-performance-analysis-methodology Type: feature Signed-off-by: Zachary Leaf <zachary.leaf@arm.com> Tested-by: Jieqiang Wang <jieqiang.wang@arm.com> Change-Id: I0620fe5b1bbe78842dfb1d0b6a060bb99e777651
2022-07-12perfmon: make less arch dependentZachary Leaf8-101/+161
In preparation for enabling perfmon on Arm platforms, move some Intel /arch specific logic into the /intel directory and update the CMake to split the common code from arch specific files. Since the dispatch_wrapper code is very different on Arm/Intel, each arch can provide their own implementation + conduct any additional arch specific config e.g. on Intel, all indexes from the mmap pages are cached. The new method intel_config_dispatch_wrapper conducts this config and returns a pointer to the dispatch wrapper to use. Similarly, is_bundle_supported() looks very different on Arm/Intel, so each implementation is to provide their own arch specific checks. Two new callbacks/function ptrs are added in PERFMON_REGISTER_SOURCE to support this - .bundle_support and .config_dispatch_wrapper.

0 is not NULL (at least not in all cases), passing 0 into a variadic function in a place where the consumer reads it as pointer might leave parts of the pointer uninitilized and hence filled with random data.

This overlap is an issue when using the 'set metadata' action in the ip ACL node which updates both fields Type: fix Change-Id: I5d35bdae97b96c3cae534e859b63950fb500ff50 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2022-06-28ipsec: introduce spd fast path typesPiotr Bronowski1-0/+63
This patch introdcues basic types supporting fast path lookup. Fast path performs policy matching with use of hash lookup (particularly bihash tries has been used for that purpose). Fast path lookup addresses situation where huge number of policies is created (~100k or more). In such scenario adding/removing a policy and policy matching is not efficient and poorly scales (for example adding 500k policies takes a few hours. Also lookup time increases significantly). With fast path adding and matching up to 1M flows scales up linearly (adding 1M of policies takes about 150s on the test machine vs many hours in case of original implementation, also matching time is significantly improved). Fast path will not deal well with a huge number of policies that are spanning large ip/port ranges. Large range will be masked out almost entirely leaving only a few bits for calculating the hash key. Such keys will tend to gather much more policies than other keys and hash will match most of the packets anihilating advantages of hashing. Having said that we also think that it is not the real life scenario. Type: feature Signed-off-by: Piotr Bronowski <piotrx.bronowski@intel.com> Change-Id: I600dae5111a37768ed4b23aa18426e66bbf7b529

2022-06-10vcl: fix iperf3 server crash issue when it runs over vpp host stack.Liangxing Wang2-1/+19
Issue: Let iperf3 server run via ldp and vcl on top of vpp's host stack. If iperf3 client connects this iperf3 server with tcp MSS setting option, iperf3 server will always crash. Root cause: When MSS option is specified by iperf3 client, iperf3 server will recreate the listening socket firstly, then call setsockopt() to set MSS immediately. Iperf3 code can be referred here: https://github.com/esnet/iperf/blob/58332f8154e2140e40a6e0ea060a418138291718/src/iperf_tcp.c#L186. However, in vcl layer vpp_evt_q of this recreated session is not allocated yet. So iperf3 server crashes with vpp_evt_q null pointer access. Fix: Add session vpp_evt_q null pointer check in vcl_session_transport_attr(). Add a vcl test case for this MSS option scenario.
