acl-plugin: avoid crash in multithreaded setup adding/deleting ACLs with traffic (VPP-910/VPP-929)

The commit fixing the VPP-910 and separating the memory operations
into separate heaps has missed setting the MHEAP_FLAG_THREAD_SAFE,
which quite obviously caused the issues in the multithread setup.
Fix that.

Also, add the debug CLIs
"set acl-plugin heap {main|hash} {validate|trace} {1|0}"
to toggle the memory instrumentation, in case we ever need it
in the future.

acl-plugin: rework the optimization 7383, fortify acl-plugin memory behavior (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

acl-plugin: fix acl plugin test failing sporadically (VPP-898)

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.

acl-plugin: VPP-897: applying of large number of ACEs is slow

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.

6 years agodevices: show interface rx-placement displays the wrong information (VPP-894) 72/7372/3
Steven [Fri, 30 Jun 2017 14:15:02 +0000 (07:15 -0700)]
devices: show interface rx-placement displays the wrong information (VPP-894)

show interface rx-placement somtimes displays the wrong interface names.
This happens when there exists subinterfaces in VPP.

The problem is due to the function show_interface_rx_placement_fn is calling
format_vnet_sw_if_index_name with hw_if_index instead of sw_if_index.

VPP has the concept of sw_if_index and hw_if_index. Each serves a different
purpose. When there is no subinterfaces, both hw_if_index and sw_if_index
may happen to have the same value.But don't count on it. When the API calls
for sw_if_index, we must pass the sw_if_index although the hw_if_index has
the same type which the compiler does not catch. Passing hw_if_index for an
API which requires sw_if_index may have an unpredictable result such as
described in the VPP-894 and sometimes it may even crash if the particular
index does not exist.

Andrew Yourtchenko [Wed, 24 May 2017 11:20:47 +0000 (13:20 +0200)]
acl-plugin: bihash-based ACL lookup

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.

memif: jumbo frames support

Current memif interface supports frame size up to 2048. This patch is to
enhance memif to support jumbo frames.

On tx (writing buffers to the ring), keep reading the next buffer in vlib
when the flag VLIB_BUFFER_NEXT_PRESENT and merge it to the same ring entry.
Use descriptor chaining if the buffer is not big enough.

On rx (reading buffers from the ring), if the packet is greater than 2048,
create multiple vlib buffers, chained with the VLIB_BUFFER_NEXT_PRESENT.

Testing:
Because the ping command provided by VPP does not support jumbo frames,
I have to use linux ping. Here is the set up that I use for testing.

VM1 --- vhost ---- VPP1 --- memif --- VPP2 --- vhost --- VM2

Create vhost-user interfaces between VM1 and VPP1 and between VPP2 and VM2

VM configuration:
Set the interface mtu on the VM, e.g 9216 to support jumbo frames.
create static route and static arp on VM1 to VM2 and vice versa.
Use iperf3 or ping -s 8000 from VM1 to VM2 or vice versa.

Sample run
sluong@ubuntu:~$ ping 131.1.1.1 -c1 -s 8000

acl-plugin: store sessions in a single hash table instead of a per-interface

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.
