From f731a710813d354d570494227a2c2eaa7c9caa88 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Mon, 30 Aug 2021 21:43:06 +0200 Subject: ethernet: T3619: rename interfaces migration scripts VyOS 1.4 already had a migrator for interfaces 20 -> 21, but this is a different one compared to the one in VyOS 1.3 - thus we bump every migration scripts version by one to have the same 20-to-21 converter in both VyOS 1.3 and 1.4. This is possible as VyOS 1.4 (sagitta) is still a highly experimental version and expected to break from time to time :(. --- src/migration-scripts/interfaces/20-to-21 | 145 ------------ src/migration-scripts/interfaces/21-to-22 | 143 ++++++++--- src/migration-scripts/interfaces/22-to-23 | 379 +++--------------------------- src/migration-scripts/interfaces/23-to-24 | 369 +++++++++++++++++++++++++++++ 4 files changed, 518 insertions(+), 518 deletions(-) delete mode 100755 src/migration-scripts/interfaces/20-to-21 create mode 100755 src/migration-scripts/interfaces/23-to-24 (limited to 'src/migration-scripts/interfaces') diff --git a/src/migration-scripts/interfaces/20-to-21 b/src/migration-scripts/interfaces/20-to-21 deleted file mode 100755 index 06e07572f..000000000 --- a/src/migration-scripts/interfaces/20-to-21 +++ /dev/null @@ -1,145 +0,0 @@ -#!/usr/bin/env python3 -# -# Copyright (C) 2021 VyOS maintainers and contributors -# -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License version 2 or later as -# published by the Free Software Foundation. -# -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

c1b298e5ec11313156eb3a9f871fe4f3cd4cbd64 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Mon, 30 Aug 2021 21:29:22 +0200 Subject: ethernet: T3619: fix VyOS 1.2 -> 1.3 performance degradation An analysis of the code base from VyOS 1.2 -> 1.3 -> 1.4 revealed the following "root-cause" VyOS 1.2 uses the "old" node.def file format for: * Generic Segmentation Offloading * Generic Receive Offloading So if any of the above settings is available on the configuration CLI, the node.def file will be executed - this is how it works. By default, this CLI option is not enabled in VyOS 1.2 - but the Linux Kernel enables offloading "under the hood" by default for GRO, GSO... which will boost the performance for users magically. With the rewrite in VyOS 1.3 of all the interface related code T1579, and especially T1637 this was moved to a new approach. There is now only one handler script which is called whenever a user changes something under the interfaces ethernet tree. The Full CLI configuration is assembled by get_interface_dict() - a wrapper for get_config_dict() which abstracts and works for all of our interface types - single source design. The problem now comes into play when the gathered configuration is actually written to the hardware, as there is no GSO, GRO or foo-offloading setting defined - we behave as instructed and disable the offloading. So the real bug originates from VyOS 1.2 and the old Vyatta codebase, but the recent XML Python rewrites brought that one up to light. Solution: A configuration migration script will be provided starting with VyOS 1.3 which will read in the CLI configuration of the ethernet interfaces and if not enabled, will query the adapter if offloading is supported at all, and if so, will enable the CLI nodes. One might say that this will "blow" the CLI configuration but it only represents the truth - which was masked in VyOS 1.2.
