2022-08-25vlib: introduce DMA infrastructureMarvin Liu6-0/+890
This patch introduces DMA infrastructure into vlib. This is well known that large amount of memory movements will drain core resource. Nowadays more and more hardware accelerators were designed out for freeing core from this burden. Meanwhile some restrictions still remained when utilizing hardware accelerators, e.g. cross numa throughput will have a significant drop compared to same node. Normally the number of hardware accelerator instances will less than cores number, not to mention that applications number will even beyond the number of cores. Some hardware may support share virtual address with cores, while others are not. Here we introduce new DMA infrastructure which can fulfill the requirements of vpp applications like session and memif and in the meantime dealing with hardware limitations. Here is some design backgrounds: Backend is the abstract of resource which allocated from DMA device and can do some basic operations like configuration, DMA copy and result query. Config is the abstract of application DMA requirement. Application need to request an unique config index from DMA infrastructure. This unique config index is associated with backend resource. Two options cpu fallback and barrier before last can be specified in config. DMA transfer will be performed by CPU when backend is busy if cpu fallback option is enabled. DMA transfer callback will be in order if barrier before last option is enabled. We constructs all the stuffs that DMA transfer request needed into DMA batch. It contains the pattern of DMA descriptors and function pointers for submission and callback. One DMA transfer request need multiple times batch update and one time batch submission. DMA backends will assigned to config's workers threads equally. Lock will be used for thread-safety if same backends assigned to multiple threads. Backend node will check all the pending requests in worker thread and do callback with the pointer of DMA batch if transfer completed. Application can utilize cookie in DMA batch for selves usage.

2022-08-18nat: Replace port refcounts with simple bitvectorsJon Loeliger2-17/+80
Previously, each address maintained an array of 32-bit reference counts for each of 65K possible ports for each of 4 NAT protocols. Totalling 1MB per address. Wow. A close read of the code shows that an "is used" check precedes each attempted reference count increment. That means the refcount never actually gets above 1. That in turn means algorithmically, a bit vector is sufficient. And one need not be allocated for more than the highest validated port referenced. These changes introduce a dynamically sized bit vector replacing the reference counts, for a maximum of 32K if all 4 protocols use port 65535. In fact, protocol OTHER is never used, so at most 24K will be used, and none of it will be "statically" allocated per address.

2022-08-17memif: crash on recceiving a bad descriptorSteven Luong1-1/+1
We validate each descriptor via memif_validate_desc_data and set desc_status to non-zero for the corresponding descriptor when the descriptor is bad. However, desc_status is not propagated back to xor_status in memif_validate_desc_data which eventually sets ptd->xor_status. Not setting ptd->xor_status causes us to treat all descriptors as "simple". In that case, when we try to copy also the bad descriptors to the buffers, it results a crash since desc_data is not set to point to the correct memory in the descriptor. The fix is to set xor_status in memif_validate_desc_data such that if there is a bad descriptor in the frame, "is_simple" is set to false and we have to selectively copy only the good descriptors to the buffers.

2022-08-17wireguard: fix fib entry trackingAlexander Chernavin2-53/+35
Type: fix After peers roaming support addition, FIB entry tracking stopped working. For example, it can be observed when an adjacency is stacked on a FIB entry by the plugin and the FIB entry hasn't got ARP resolution yet. Once the FIB entry gets ARP resolution, the adjacency is not re-stacked as it used to. This results in endless ARP requests when a traffic is sent via the adjacency. This is broken because the plugin stopped using "midchain delegate" with peers roaming support addition. The reason is that "midchain delegate" didn't support stacking on a different FIB entry which is needed when peer's endpoint changes. Now it is supported there (added in 36892). With this fix, start using "midchane delegate" again and thus, fix FIB entry tracking. Also, cover this in tests.

2022-08-16nat: fix potential out-of-bound worker array indexJing Peng3-24/+36
In several NAT submodules, the number of available ports (0xffff - 1024) may not be divisible by the number of workers, so port_per_thread is determined by integer division, which is the floor of the quotient. Later when a worker index is needed, dividing the port with port_per_thread may yield an out-of-bound array index into the workers array. As an example, assume 2 workers are configured, then port_per_thread will be (0xffff - 1024) / 2, which is 32255. When we compute a worker index with port 0xffff, we get (0xffff - 1024) / 32255, which is 2, but since we only have 2 workers, only 0 and 1 are valid indices. This patch fixes the problem by adding a modulo at the end of the division. Type: fix Signed-off-by: Jing Peng <pj.hades@gmail.com> Change-Id: Ieae3d5faf716410422610484a68222f1c957f3f8

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.

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
