2022-04-04vppinfra: make _vec_len() read-onlyDamjan Marion1-2/+3
Use of _vec_len() to set vector length breaks address sanitizer. Users should use vec_set_len(), vec_inc_len(), vec_dec_len () instead. Type: improvement Change-Id: I441ae948771eb21c23a61f3ff9163bdad74a2cb8 Signed-off-by: Damjan Marion <damarion@cisco.com>
2021-12-20ip: SVR fix race conditionKlement Sekera1-1/+7
There could be a race condition where two fragments of one chain end up at the same time on different workers, one overwriting others hash entry. Add a check for that and restart processing on the unlucky worker who ends up being second from hash table POV. This will then result in a proper handover to worker now owning this reassembly.

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 Nikolaev1-0/+4
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

2020-01-15ip: align reass.save_rewrite_lengthv20.05-rc0Klement Sekera1-7/+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.
