2018-02-06Reflexive ACL support on ICMPSteve Shin1-25/+113
Normally session keys are generated by mirroring the packets sent. ICMP message type should be used and inverted for the stateful ACL. Supported ICMP messages with this patch: - ICMPv4: Echo/Timestamp/Information/Address Mask requests - ICMPv6: Echo request/Node Information Queury The invmap & valid_new tables can be modified to make any other ICMP messages to be reflexive ACL.

Clients cannot know at svm region detach time if the shm backing files have been recreated (e.g., if vpp restarts) and therefore should not try to unlink them. Otherwise, terminating clients attached to previous instantiations of a re-allocated region end up making the new instance un-mappable by removing its backing file.

2018-02-01Out-of-order data chunks handling and moreMarco Varlese4-69/+235
This patch addresses the need to handle out-of-order data chunks received by a peer. To do that effectively, we had to add the handling of data chunks flags (E/B/U bit) to understand whether the stream is fragmenting user-message data and in that case if a fragment is the FIRST/MIDDLE/LAST one of a transmission. The same patch also addresses the security requirement to have a HMAC calculated and incorporated in the INIT_ACK and COOKIE_ECHO chunks. The algorithm used is the HMAC-SHA1.

2018-02-01vxlan: Lookup FIB in either IPv4 or IPv6 families.Jon Loeliger1-4/+5
Prior to this commit, the VXLAN "create" API assumed the vrf_id belonged to only the IPv4 FIB tables space. With this commit, the FIB table is found in either the IPv4 or IPv6 table as determined by the is_ipv6 flag. This follows the same pattern that was already being done in the CLI code for the VXLAN "create" command.

2018-02-01Add flowhash hash table to vppinfraPierre Pfister5-0/+1009
This hash table intends to provide an alternative to the widely used bihash table in places where either: - Hash entry timeout is required - The hash table data does not fit in CPU cache Although the bihash table is very fast, each lookup requires accessing two cache lines in a serialized fashion. It works fine when the hash table is in cache, but hits a wall when it does not. The 'flowhash' table uses a simplified design (at the cost of a less good bucket auto-scaling) where each access only requires a single memory lookup (in the absence of collision). The hash table also uses a reduced number of registers. In practice, a VPP node implementing a stateful feature would typically: - prefetch buffer metadata (in-cache) - prefetch packet header (in-cache) - compute hash & prefetch hash bucket (possibly in RAM) - read/write key and value from bucket Using this hash table, it is possible to pipeline accesses in a way that does not exhaust CPU's line field buffers, even when the requested value is located in RAM (i.e. not in cache). Measurements showed it was possible to scale to tens of millions of flows (with a full 5-tuple matching and 32B value, i.e. 1 cache line per flow) with no performance degradation when the hash table grows to the point it doesn't fit in cache anymore. I have used this table in a couple of non-open-sourced projects, but think it might be useful to lb, nat, and possibly other VPP subsystems. More information in the .h file.

2018-01-31vlib: allocating buffers on thread-x and freeing them on thread-y causesSteven4-25/+17
a crash on debug image (VPP-1151) In debug image, there is extra code to validate the buffer when it is freed. It uses the hash table to lookup the buffer index with spinlock to prevent contention. However, there is one spinlock for each worker thread. So allocating the buffer on thread-x and freeing the same buffer on thread-y causes the validation to fail on thread-y. The fix is to have only one spinlock, stored in vlib_global_main.

It adds the possibility to queue up to 2 SACKs chunks when the connection is not gapping. At the same time, it pushes some variable/field renaming for better readibility.

Add an SELinux profile such that VPP can run under SELinux on RPM based platforms. The SELinux Policy is currently only implemented for RPM packages, specifically, Fedora, CentOS and RHEL. Doxygen User Documentation has been included (selinux_doc.md). Once some discussion on file locations has completed (see vpp-devlist), updates to the Debug CLI documentation will also need to be updated. Additional changes: Patch Set 2: - Rework selinux_doc.md such that each line is only 80 characters instead of each sentence on a line. Made additonal minor chnages to the text. - Update vHost Debug CLI documentation to reflex new socket location. Cleaned up some text from when I originally wrote it, to better reflex proper use. - Update exec Debug CLI documentation to be more inline with suggested helptext, added text regarding recommended script file location. - For Debian builds, create the /var/log/vpp/ directory. I don't use Debian very much, so please pay extra attention to build-data/platforms.mk and build-root/deb/debian/.gitignore. - Per discussion on VPP call, changed the default log location to /var/log/vpp/vpp.log. - Changed the socket location for vHost in AutoConfig to /var/run/vpp/. Patch Set 3: - Update selinux_doc.md based on comments. Change-Id: I400520dc33f1ca51012d09ef8fe5a7b7b96c631e Signed-off-by: Billy McFall <bmcfall@redhat.com>
