2017-05-07Avoid active connection prevent timeout of idle conns after itAndrew Yourtchenko1-9/+10
Fix a logic error related to timing out of the connections following the active one. To avoid this class of issue in the future, create corresponding testcases, as well as some trivial sanity testcases for both IPv4 and IPv6. 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 Yourtchenko1-9/+61
(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.
