2020-02-10ip: more detailed show reassembly commandsVladimir Ratnikov4-7/+33
Options like: expire_walk_interval_ms,max_reassemblies,timeout_ms can be configured via API, but it's impossible to check them using vppctl, but this can be a useful feature Type: feature Signed-off-by: Vladimir Ratnikov <vratnikov@netgate.com> Change-Id: Iac8a96201a7a70b82e9852edc89b819c5d451a58
2020-01-15ip: align reass.save_rewrite_lengthv20.05-rc0Klement Sekera2-16/+0
By aligning vnet_buffer_opaque.ip.save_rewrite_length and vnet_buffer_opaque.ip.reass.save_rewrite_length we prevent shallow virtual reassembly code from overwrite save_rewrite_length, allowing other features down the pipe to rely on this value. A static assert is added to guard this alignment.

2020-01-03nat: use SVRKlement Sekera3-48/+262
Remove NAT's implementation of shallow virtual reassembly with corresponding CLIs, APIs & tests. Replace with standalone shallow virtual reassembly provided by ipX-sv-reass* nodes. Type: refactor Change-Id: I7e6c7487a5a500d591f6871474a359e0993e59b6 Signed-off-by: Klement Sekera <ksekera@cisco.com>

This change adds tracing of IP headers when doing a handoff between worker threads. This eases debugging. Type: feature Change-Id: I2195b070a364cba13a658ec1cee5154fc4c3a8b0 Signed-off-by: Klement Sekera <ksekera@cisco.com>
2019-10-09map: use ip6-full-reassembly instead of own codeKlement Sekera4-0/+70
Remove map's implementation of reassembly and use common ip6-full-reassembly functionality. This makes it easier to maintain by removing duplicate code/functionality. Type: refactor Change-Id: I430e888b704e28c100a9ce075d1460cb529e4676 Signed-off-by: Klement Sekera <ksekera@cisco.com>

Reference counts need to be per-interface as opposed to global. This allows configuring the feature on more than one interface correctly. Type: fix Fixes: de34c35fc73226943538149fae9dbc5cfbdc6e75 Change-Id: I05534ac59fa86e67290737ec6c61df2c19acab48 Signed-off-by: Klement Sekera <ksekera@cisco.com>
