Several conflicts here. NFP driver bug fix adding nfp_netdev_is_nfp_repr() check to nfp_fl_output() needed some adjustments because the code block is in an else block now. Parallel additions to net/pkt_cls.h and net/sch_generic.h A bug fix in __tcp_retransmit_skb() conflicted with some of the rbtree changes in net-next. The tc action RCU callback fixes in 'net' had some overlap with some of the recent tcf_block reworking. Signed-off-by: David S. Miller <davem@davemloft.net>
2017-10-29selftests: Introduce a new test case to tc testsuiteChris Mi3-5/+40
In this patchset, we fixed a tc bug. This patch adds the test case that reproduces the bug. To run this test case, user should specify an existing NIC device: # sudo ./tdc.py -d enp4s0f0 This test case belongs to category "flower". If user doesn't specify a NIC device, the test cases belong to "flower" will not be run. In this test case, we create 1M filters and all filters share the same action. When destroying all filters, kernel should not panic. It takes about 18s to run it.

2017-10-15tc-testing: fix the -l argument bug in tdc.pyLucas Bates1-4/+4
This patch fixes a bug in the tdc script, where executing tdc with the -l argument would cause the tests to start running as opposed to listing all the known test cases.

2017-10-15tc-testing: Split test case files into smaller chunksLucas Bates6-1212/+1194
The original submission had the test cases stored in one monolithic file. This can be unwieldy to edit, especially as more test cases are added. This patch removes the original tests.json file in favour of individual ones broken down by category.

2017-10-15tc-testing: Add test cases for flushing actionsLucas Bates1-1/+48
Tests for flushing gact and mirred were missing. This patch adds test cases to explicitly test the flush of any installed gact/mirred actions. Signed-off-by: Lucas Bates <lucasb@mojatatu.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-08-30tc-testing: add test for testing ife typeAlexander Aring1-0/+50
This patch adds a new testcase for the IFE type setting in tc. In case of user specified the type it will check if the ife is correctly configured to react on it. If it's not specified the default IFE type should be used. Signed-off-by: Alexander Aring <aring@mojatatu.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.

2017-06-20selftests: Introduce tc testsuiteLucas Bates10-0/+1863
Add the beginnings of a testsuite for tc functionality in the kernel. These are a series of unit tests that use the tc executable and verify the success of those commands by checking both the exit codes and the output from tc's 'show' operation. To run the tests: # cd tools/testing/selftests/tc-testing # sudo ./tdc.py You can specify the tc executable to use with the -p argument on the command line or editing the 'TC' variable in tdc_config.py. Refer to the README for full details on how to run. The initial complement of test cases are limited mostly to tc actions. Test cases are most welcome; see the creating-testcases subdirectory for help in creating them.
