2017-09-12acl-plugin: add startup-config section "acl-plugin" and heap/hash parametersAndrew Yourtchenko3-4/+60
This adds the ability to tweak the memory allocation parameters of the ACL plugin from the startup config. It may be useful in the cases involving higher limit of the connections than the default 1M, or the high number of cores.

(complete the fix for VPP-935) The fix for VPP-935 missed the case that hash_acl_add() and hash_acl_delete() may be called during the replacement of the existing applied ACL, as a result the "applied" logic needs to be replicated for the hash acls separately, since it is a lower layer.

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. Ensure we are not spending too much time spinning in a tight cycle by suspending the main cleaner thread until the current iteration of interrupts is processed.

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. Thus, make a local copy of for which ACL indices the hash_acl_apply was called previously, and maintain that one local to the hash_lookup.c file logic.

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.

2017-06-19acl-plugin: bihash-based ACL lookupAndrew Yourtchenko9-10/+1571
Add a bihash-based ACL lookup mechanism and make it a new default. This changes the time required to lookup a 5-tuple match from O(total_N_entries) to O(total_N_mask_types), where "mask type" is an overall mask on the 5-tuple required to represent an ACE. For testing/comparison there is a temporary debug CLI "set acl-plugin use-hash-acl-matching {0|1}", which, when set to 0, makes the plugin use the "old" linear lookup, and when set to 1, makes it use the hash-based lookup. Based on the discussions on vpp-dev mailing list, prevent assigning the ACL index to an interface, when the ACL with that index is not defined, also prevent deleting an ACL if that ACL is applied. Also, for the easier debugging of the state, there are new debug CLI commands to see the ACL plugin state at several layers: "show acl-plugin acl [index N]" - show a high-level ACL representation, used for the linear lookup and as a base for building the hashtable-based lookup. Also shows if a given ACL is applied somewhere. "show acl-plugin interface [sw_if_index N]" - show which interfaces have which ACL(s) applied. "show acl-plugin tables" - a lower-level debug command used to see the state of all of the related data structures at once. There are specifiers possible, which make for a more focused and maybe augmented output: "show acl-plugin tables acl [index N]" show the "bitmask-ready" representations of the ACLs, we well as the mask types and their associated indices. "show acl-plutin tables mask" show the derived mask types and their indices only. "show acl-plugin tables applied [sw_if_index N]" show the table of all of the ACEs applied for a given sw_if_index or all interfaces. "show acl-plugin tables hash [verbose N]" show the 48x8 bihash used for the ACL lookup. Change-Id: I89fff051424cb44bcb189e3cee04c1b8f76efc28 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2017-06-15acl-plugin: store sessions in a single hash table instead of a per-interfaceAndrew Yourtchenko4-22/+39
A bihash-per-interface is convenient, but turns out tricky difficult from the maintenance standpoint with the large number of interfaces. This patch makes the sessions reside in a single hash table for all the interfaces, adding the lower 16 bit of sw_if_index as part of the key into the previously unused space. There is a tradeoff, that a session with an identical 5-tuple and the same sw_if_index modulo 65536 will match on either of the interfaces. The probability of that is deemed sufficiently small to not worry about it. In case it still happens before the heat death of the universe, there is a clib_warning and the colliding packet will be dropped, at which point we will need to bump the hash key size by another u64, but rather not pay the cost of doing that right now.

2017-05-18acl-plugin: reject the too-short variable-length messages from clients (VPP-839)Andrew Yourtchenko1-3/+42
Prior to commit bfd9227e6da567e0e19e026afe94cd4c0b65f725, there was no clean way to check the lower-level message length as supplied by the client, so there was no option but to trust that the client does the right thing and allocates memory correctly. The absence of checks makes it hard for a misbehaving client to spot the problem - because everything "appears" to work correctly for the specific erroneous message exchange. This commit ensures the message received is at least as big as we expect, and complains loudly if it is not.

Since these tests are timing-dependent and take up time, mark them as extended tests. Change-Id: I2c72bad5efda7db8aa9cb05801fe47928dc47927 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2017-04-06acl-plugin: make the IPv4/IPv6 non-first fragment handling in line with ACL ↵Andrew Yourtchenko4-13/+77
(VPP-682) This fixes the previously-implicit "drop all non-first fragments" behavior to be more in line with security rules: a non-first fragment is treated for the purposes of matching the ACL as a packet with the port match succeeding. This allows to change the behavior to permit the fragmented packets for the default "permit specific rules" ruleset, but also gives the flexibility to block the non-initial fragments by inserting into the begining a bogus rule which would deny the L4 traffic. Also, add a knob which allows to potentially turn this behavior off in case of a dire need (and revert to dropping all non-initial fragments), via a debug CLI.
