Next meeting: 03-June, 2021
Attendees:
* Aaron
* Paolo
* Korol
* Gaetan
Agenda:
A Security concerns, raised by NVidia
- tcp_loose mode support
- Kernel supports this via sysctl knob
- Userspace has no such knob or function
- Aconole: will start work on this as a separate series
- Q: Should this be configured via ovs-appctl or ovsdb?
- synproxy support
- Not used in kernel space, not existing in userspace
- Needs more details (what is the use case, etc). Lots of technical
details missing
B Usability:
- Flow HW offloads
* Nvidia POV, wants to enable HWOL but running into issues
- Discrepencies between sw & hw datapaths
* Tcp_loose / tcp_liberal - should these be set via the DB
* Tcp_liberal / no seq checking is already defaulted in kernel, and
cannot be modified at run time
* Aconole: Maybe we can fire an RFC to match this behavior
* Should tcp_liberal be configurable via the OVSDB, or tied to HWOL?
- IP Fragmentation behavior in kernel does not match userspace
* Userspace ct() calls do not lose fragment boundaries, while
kernel space ct() calls can:
