format from hex representation Even though the trace now prints the hex as well as human readable format for acl plugin, it can be handy to have a separate function which allows to decode the hex.

2017-12-11acl-plugin: unapply/reapply the classifier-based inacls when performing ↵Andrew Yourtchenko1-1/+29
macip_acl_add_replace on an existing MACIP ACL The classifier tables layout might (and most always will) change during the MACIP ACL modification. Furthermore, vnet_set_input_acl_intfc() is quite a picky creature - it quietly does nothing if there is an existing inacl applied, even if the number is different, so a simple "reapply" does not work. So, cleanly remove inacl, then reapply when the new tables are ready. Also, fix the testcase which was supposed to test this exact behavior. Thanks to Jon Loeliger for spotting this issue.

In multithread setup the main thread may send packets, which may pass through the node with permit+reflect action. This creates the connection in lists for thread0, however in multithread there are no interupt handlers there.

interface (VPP-935) The logic in hash ACL bitmask update was using the vector of ACLs applied to the interface to rebuild the hash lookup mask. However, in transient cases (like doing group manipulation with hash ACLs), that will not hold true.

2017-08-08acl-plugin: rework the optimization 7383, fortify acl-plugin memory behavior ↵Andrew Yourtchenko5-150/+289
(VPP-910) The further prolonged testing from testbed that reported VPP-910 has uncovered a couple of deeper issues with optimization from 7384, and the usage of subscripts rather than vec_elt_at_index() allowed to hide a couple of further errors in the code. Also, the current acl-plugin behavior of using the global heap for its dynamic data is problematic - it makes the troubleshooting much harder by potentially spreading the problem around. Based on this experience, this commits makes a few changes to fix the issues seen, also improving the serviceability of the acl-plugin code for the future: - Use separate mheaps for any ACL-related control plane operations and separate for the hash lookup datastructures, to compartmentalize any memory-related issues for the ACL plugin. - Ensure vec_elt_at_index() usage throughout the hash_lookup.c file. - Use vectors rather than raw memory for storing the "ordinary" ACL rules. - Rework the optimization from 7384 to use a separate tail pointer rather than overloading the "prev" field. - Make get_session_ptr() more conservative and adjust is_valid_session_ptr accordingly Change-Id: Ifda85193f361de5ed3782a4acd39622bd33c5830 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> (cherry picked from commit bd9c5ffe39e9ce61db95d74d150e07d738f24da1)

2017-07-20acl-plugin: assertion failed at hash_lookup.c:226 when modifying ACLs ↵Andrew Yourtchenko1-0/+11
applied as part of many (VPP-910) change 7385 has added the code which has the first ACE's "prev" entry within the linked list of shadowed ACEs pointing to the last ACE, in order to avoid the frequent linear list traversal. That change was not complete and did not update this "prev" entry whenever the last ACE was deleted. As a result the changes within the applied ACLs which caused the calls to hash_acl_unapply/hash_acl_apply may result in hitting assert which does the sanity check. The solution is to add the missing update logic.

2017-07-04acl-plugin: VPP-897: applying of large number of ACEs is slowAndrew Yourtchenko2-20/+45
When applying ACEs, in the new hash-based scheme, for each ACE the lookup in the hash table is done, and either that ACE is added to the end of the existing list if there is a match, or a new list is created if there is no match. Usually ACEs do not overlap, so this operation is fast, however, the fragment-permit entries in case of a large number of ACLs create a huge list which needs to be traversed for every other ACE being added, slowing down the process dramatically. The solution is to add an explicit flag to denote the first element of the chain, and use the "prev" index of that element to point to the tail element. The "next" field of the last element is still ~0 and if we touch that one, we do the linear search to find the first one, but that is a relatively infrequent operation.

2017-07-04acl-plugin: fix acl plugin test failing sporadically (VPP-898)Andrew Yourtchenko1-0/+5
The "acl_plugin" tests has one of the tests sporadically fail with the following traceback: r.reply.decode().rstrip('\x00') UnicodeDecodeError: 'ascii' codec can't decode byte 0xd8 in position 20666: ordinal not in range(128) This occurs in the newly added "show acl-plugin table" debug CLI. This CLI has only the numeric outputs, so the conclusion is that it is the incorrect termination (trailing zero) that might be most probably causing it. The other acl-plugins show commands also lack the zero-termination termination, so fix all of them. The particularity of this command vs. the other acl-plugin debug CLIs is that the accumulator is freed and allocated multiple times, this might explain the issue is not seen with them.
