Subject: [dpdk-dev] [PATCH v6 0/6] TAP RSS eBPF cover letter
Date: Sat, 20 Jan 2018 21:11:31 +0000 [thread overview]
Message-ID: <1516482697-8348-1-git-send-email-ophirmu@mellanox.com> (raw)
In-Reply-To: <1516282691-29698-1-git-send-email-ophirmu@mellanox.com>
The patches of TAP RSS eBPF follow the RFC on this issue
https://dpdk.org/dev/patchwork/patch/31781/
v6 changes with respect to v5
=============================
1. Reorder thes following commits (source file commit before byte code commit)
net/tap: add eBPF program file
net/tap: add eBPF bytes code
2. Add acknowledgment to commits
v5 changes with respect to v4
=============================
Update TAP document guide with RSS
v4 changes with respect to v3
=============================
* Code updates based on review comments
* New commits organization (2-->5) based on review comments
1. net/tap: support actions for different classifiers (preparations for BPF.
No BPF code yet)
2. net/tap: add eBPF bytes code (BPF bytes code in a separate file)
3. net/tap: add eBPF program file (Program source code of bytes code)
4. net/tap: add eBPF API (BPF API to be used by TAP)
5. net/tap: implement TAP RSS using eBPF
v3 changes with respect to v2
=============================
* Add support for IPv6 RSS in BPF program
* Bug fixes
* Updated compatibility to kernel versions:
eBPF requires Linux version 4.9 configured with BPF
* New license header (SPDX) for newly added files
v2 changes with respect to v1
=============================
* v2 has new commits organization (3 --> 2)
* BPF program was revised. It is successfully tested on
IPv4 L3 L4 layers (compatible to mlx4 device)
* Licensing: no comments received for using "Dual BSD/GPL"
string during BPF program loading to the kernel.
(v1 and v2 are using the same license strings)
Any comments are welcome.
* Compatibility to kernel versions:
eBPF requires Linux version 4.2 configured with BPF. TAP PMD will
successfully compile on systems with old or non-BPF configured kernels.
During compilation time the required Linux headers are searched for.
If they are not present missing definitions are locally added
(tap_autoconf.h).
If the kernel cannot support a BPF operation - at runtime it will
gracefully reject the netlink message (with BPF) sent to it.
Ophir Munk (6):
net/tap: support actions for different classifiers
net/tap: add eBPF program file
net/tap: add eBPF bytes code
net/tap: add eBPF API
net/tap: implement TAP RSS using eBPF
