selftests: Add test for timing a bind request to a port with a populated bhash entry

2022-05-21T01:16:24Z

This test populates the bhash table for a given port with MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long a bind request on the port takes. When populating the bhash table, we create the sockets and then bind the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT are set). When timing how long a bind on the port takes, we bind on a different address without SO_REUSEPORT set. We do not set SO_REUSEPORT because we are interested in the case where the bind request does not go through the tb->fastreuseport path, which is fragile (eg tb->fastreuseport path does not work if binding with a different uid). To run the test locally, I did: * ulimit -n 65535000 * ip addr add 2001:0db8:0:f101::1 dev eth0 * ./bind_bhash_test 443 Signed-off-by: Joanne Koong Signed-off-by: Jakub Kicinski

selftest/net/xfrm: Add test for ipsec tunnel

2020-09-24T06:53:04Z

It's an exhaustive testing for ipsec: covering all encryption/ authentication/compression algorithms. The tests are run in two network namespaces, connected by veth interfaces. To make exhaustive testing less time-consuming, the tests are run in parallel tasks, specified by parameter to the selftest. As the patches set adds support for xfrm in compatible tasks, there are tests to check structures that differ in size between 64-bit and 32-bit applications. The selftest doesn't use libnl so that it can be easily compiled as compatible application and don't require compatible .so. Here is a diagram of the selftest: --------------- | selftest | | (parent) | --------------- | | | (pipe) | ---------- / | | \ /------------- / \ -------------\ | /----- -----\ | ---------|----------|----------------|----------|--------- | --------- --------- --------- --------- | | | child | | child | NS A | child | | child | | | --------- --------- --------- --------- | -------|------------|----------------|-------------|------ veth0 veth1 veth2 vethN ---------|------------|----------------|-------------|---------- | ------------ ------------ ------------ ------------ | | | gr.child | | gr.child | NS B | gr.child | | gr.child | | | ------------ ------------ ------------ ------------ | ---------------------------------------------------------------- The parent sends the description of a test (xfrm parameters) to the child, the child and grand child setup a tunnel over veth interface and test it by sending udp packets.

Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26Z

Pull SPDX updates from Greg KH: "Here are three SPDX patches for 5.7-rc1. One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All three of these have been in linux-next for a while, with no reported issues other than the merge conflict" * tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: ASoC: MT6660: make spdxcheck.py happy .gitignore: add SPDX License Identifier .gitignore: remove too obvious comments
