2018-03-27acl-plugin: autosize the ACL plugin heap and fix the heap size types and parsingAndrew Yourtchenko1-5/+38
- autosize the ACL plugin heap size based on the number of workers - for manual heap size setting, use the proper types (uword), and proper format/unformat functions (unformat_memory_size) Change-Id: I7c46134e949862a0abc9087d7232402fc5a95ad8 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2018-03-26acl-plugin: defer the ACL plugin user module registration with ACL lookup ↵Andrew Yourtchenko1-3/+5
until it is needed Registering ACL plugin user module within the "ACL as a service" infra during the plugin init causes an unnecesary ACL heap allocation and prevents the changing of the ACL heap size from the startup config. Defer this registration until just before it is needed - i.e. when applying an ACL to an interface.

other plugins This code implements the functionality required for other plugins wishing to perform ACL lookups in the contexts of their choice, rather than only in the context of the interface in/out. The lookups are the stateless ACLs - there is no concept of "direction" within the context, hence no concept of "connection" either.

2018-02-08acl-plugin: add whitelisted ethertype mode (VPP-1163)Andrew Yourtchenko1-5/+198
Currently, ACL plugin largely does not care about the ethertypes other than 0x0800 (IPv4) and 0x86dd (IPv6), the only exception being 0x0806 (ARP), which is dealt with by the MACIP ACLs. The other ethertypes in L2 mode are just let through. This adds a new API message acl_interface_set_etype_whitelist, which allows to flip the mode of a given interface into "ethertype whitelist mode": the caller of this message must supply the two lists (inbound and outbound) of the ethertypes that are to be permitted, the rest of the ethertypes are dropped. The whitelisting for a given interface and direction takes effect only when a policy ACL is also applied. This operates on the same classifier node as the one used for dispatching the policy ACL, thus, if one wishes for most of the reasonable IPv4 deployments to continue to operate within the whitelist mode, they must permit ARP ethertype (0x0806) The empty list for a given direction resets the processing to allow the unknown ethertypes. So, if one wants to just permit the IPv4 and IPv6 and nothing else, one can add their ethertypes to the whitelist. Add the "show acl-plugin interface" corresponding outputs about the whitelists, vat command, and unittests.

2018-02-08acl-plugin: VPP-1088: add support for egress filter in macip ACLsAndrew Yourtchenko1-16/+240
This is the second patch, using the new functionality from the change 10002 in order to implement the egress filtering on the MACIP ACLs. This adds an action "2" which means "add also egress filtering rules for this MACIP ACL. The reason for having the two choices is that the egress filtering really takes care of a fairly corner case scenario, and I am not convinced that always adding the performance cost of the egress lookup check is worth it. Also, of course, not breaking the existing implementations is a nice plus, too. Change-Id: I3d7883ed45b1cdf98d7303771bcc75951dff38f0 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2018-02-08acl-plugin: an elog-based tracing implementation for troubleshooting the ↵Andrew Yourtchenko1-0/+15
conn cleaner threads interactions This replaces some of the early-stage commented-out printf()s with an elog-based debug collector. It is aimed to be "better than nothing" initial implementation to be available in the field. It will be refined/updated based on use. This initial code is focused on the main/worker threads interactions, hence uses just the worker tracks. This code adds a developer debug CLI "set acl-plugin session table event-trace 1", which allows to gather the events pertaining to connection cleaning. The CLI is deliberately not part of the online help, as the express declaration that the semantics/trace levels, etc. are subject to change without notice.

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-1/+1
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.

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.

2017-08-08acl-plugin: rework the optimization 7383, fortify acl-plugin memory behavior ↵Andrew Yourtchenko1-42/+114
(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)

(VPP-912) Fix several threading-related issues uncovered by the CSIT scale/performance test: - make the per-interface add/del counters per-thread - preallocate the per-worker session pools rather than attempting to resize them within the datapath - move the bihash initialization to the moment of ACL being applied rather than later during the connection creation - adjust the connection cleaning logic to not require the signaling from workers to main thread - make the connection lists check in the main thread robust against workers updating the list heads at the same time - add more information to "show acl-plugin sessions" to aid in debugging Change-Id: If82ef715e4993614df11db5e9afa7fa6b522d9bc Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> (cherry picked from commit 8e4222fc7e23a478b021930ade3cb7d20938e398)
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.

2017-06-22acl-plugin: clean up the code enabling/disabling acl-plugin processing on ↵Andrew Yourtchenko1-4/+16
interface Multiple subsequent calls to vnet_feature_enable_disable() to enable the feature cause the feature to be inserted into the processing graph multiple times in a row. This might be argued to be a bug in that function, but enabling already enabled feature is suboptimal anyway, so avoid that. The existing tests already catch this issue whenever the ASSERT() part of this patch was added.
