Type: feature Currently, if a handshake message is sent and a cookie message is received in reply, the cookie message will be ignored. Thus, further handshake messages will not have valid mac2 and handshake will not be able to be completed.

2022-07-12perfmon: enable perfmon plugin for ArmZachary Leaf11-35/+654
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.

2022-06-05wireguard: fix crash by not sending arp via wg interfaceAlexander Chernavin2-1/+9
Type: fix Currently, neighbor adjacencies on a wg interface are converted into a midchain only if one of the peers has a matching allowed prefix configured. If create a route that goes through a wg interface but the next-hop address does not match any allowed prefixes, an ARP/ND request will try to be sent via the wg interface to resolve the next-hop address when matching traffic occurs. And sending an ARP request will cause VPP to crash while copying hardware address of the wg interface which is NULL. Sending an ND message will not cause VPP to crash but the error logged will be unclear (no source address). With this fix, convert all neighbor adjacencies on a wg interface into a midchain and update tests to cover the case. If there is no matching allowed prefix configured, traffic going such routes will be dropped because of "Peer error". No changes if there is matching allowed prefix configured. Also, fix getting peer by adjacency index. Signed-off-by: Alexander Chernavin <achernavin@netgate.com> Change-Id: I15bc1e1f83de719e97edf3f7210a5359a35bddbd

2022-05-31nat: disable nat44-ei-in2out-output ttl checkAlexander Skorichenko1-3/+3
Type: fix A packet passing through nat44-ei-in2out-output, has its ttl value validated in earlier nodes. "ip4-input" node checks ttl for locally generated packets. "ip4-rewrite" node validates ttl in forwarded packets. Thus for example, the ED counterpart disables ttl checks in its "nat44-ed-in2out-output" node. This patch updates nat44 EI conditions for ttl checks to those currently used in nat44 ED case, meaning no extra ttl validation for in2out when output-feature is enabled.

Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.
