2019-09-02acl: perform a sanity check of ACL rules before creating ACLAndrew Yourtchenko1-0/+65
Adding acl with incorrect arguments like 1.1.1.1/24 (instead of 1.1.1.0/24) don't cause a disaster, but doesn't match either, as some might expect. Add an explicit sanity check which returns an error. Type: fix Change-Id: Id1601f4b9c9887d3e7e70aac419d1f1de0c0e012 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2019-07-24acl: implement countersAndrew Yourtchenko5-9/+183
implement per-acl-number counters in the stats segment. They are created during the ACL creation, the counters are incremented in the dataplane using the new inline function with the extra parameter being the packet size. Counting in shared segment adds a noticeable overhead, so add also an API to turn the counters on.

2019-07-09acl: perform the ACL-as-a-service user registrations in global heapAndrew Yourtchenko2-10/+14
Some users tend to call registration routine long before they need that service - which triggers an immediate initialization of the ACL heap, which is rather big. This commit defers this process by keeping the registrations in the global heap. Change-Id: I5825871bd836851942b55184b6ee2657c7a9cc33 Type: fix Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2019-07-09vat: unload unused vat pluginsDave Barach1-18/+2
If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.

2019-04-10API: Fix shared memory only action handlers.Ole Troan1-7/+5
Some API action handlers called vl_msg_ai_send_shmem() directly. That breaks Unix domain socket API transport.

-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).

With a test with large number of ACEs these numbers contribute to heap fragmentation noticeably. Minimize the number of allocations by preallocating the known size and then resetting the length accordingly, and then calling vec_add1() Also unify the parsing of the memory-related startup config parameters.

2018-10-04acl-plugin: tuplemerge: avoid batch-resize of the applied entries vector - ↵Andrew Yourtchenko1-2/+6
VPP-1352 If the number of rules within a given partition exceeds the limit, the split_partition() might get called, in which we calculate the relaxed mask, create a new partition with that mask and attempt to reallocate some entries from the overcrowded partition. The non-TM code was pre-expanding the vector with rules by the number of rules in the new ACL being applied - which caused the split_partition() to iterate over the rules filled with zeroes. Most of the time it is benign, but if a newly created relaxed partition is such that these entries can be "relocated", then the code attempts to do so, which does not end well.
