The CI occasionaly encounters a failing test run. Example: # PASS: ipsec tunnel mode for ns1/ns2 # re-run with random mtus: -o 10966 -l 19499 -r 31322 # PASS: flow offloaded for ns1/ns2 [..] # FAIL: ipsec tunnel ... counter 1157059 exceeds expected value 878489 This script will re-exec itself, on the second run, random MTUs are chosen for the involved links. This is done so we can cover different combinations (large mtu on client, small on server, link has lowest mtu, etc). Furthermore, file size is random, even for the first run. Rework this script and always use the same file size on initial run so that at least the first round can be expected to have reproducible behavior. Second round will use random mtu/filesize. Raise the failure limit to that of the file size, this should avoid all errneous test errors. Currently, first fin will remove the offload, so if one peer is already closing remaining data is handled by classic path, which result in larger-than-expected counter and a test failure. Given packet path also counts tcp/ip headers, in case offload is completely broken this test will still fail (as expected). The test counter limit could be made more strict again in the future once flowtable can keep a connection in offloaded state until FINs in both directions were seen.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
