2021-11-04ip: speed up reassembly code compilationKlement Sekera4-50/+36
Refactor code so that code is inlined in one place instead of in multiple to speed up compilation. Type: refactor Change-Id: I41357b89715b66ebdc8c0d5ccd69347a254fc266 Signed-off-by: Klement Sekera <ksekera@cisco.com>
2021-11-04ip: reassembly: avoid reading truncated L4 headersKlement Sekera2-80/+149
Check if L4 headers are truncated and if so, set a flag for (future) consumers instead of reading/writing garbage data. Type: fix Fixes: de34c35fc73226943538149fae9dbc5cfbdc6e75 Change-Id: I0b656ec103a11c356b98a6f36cad98536a78d1dc Signed-off-by: Klement Sekera <ksekera@cisco.com>

2021-04-01ip: extend show cmd of ip reassembly configurationAnton Nikolaev4-0/+16
Type: feature Add output of field maximum reassembly length with others ip reassembly configuration fields. This field can be configured via vpp API, but there was no output of this field in vpp cli. Output added for ipv4/ipv6 and full/shallow virtual nodes. Signed-off-by: Anton Nikolaev <anikolaev@netgate.com> Change-Id: Ibbd61aab26189d4a93d32e047d8f4e589fe9f8a5
2020-12-27ip: Use full reassembly for fragments in ip6-localNeale Ranns1-2/+0
Type: fix shallow was the default, but probably by accident as it depended on module load order. full assembly is the v4 behaviour. using proper types allows gdb to print enum names.

2020-04-27ip: reassembly: fix one possible use-after-freeGao Feng2-10/+11
When use the kv->v.memory_owner_thread_index as the index to get the reass in pool, maybe this element is freed by the owner thread because of timeout, too many fragments, and so on. So we should check if do_handoff with kv->v.memory_owner_thread_index before get the reass from pool.

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.
